Other versions in the supported contributor range can order equivalent platform markers differently; export verification compares files byte-for-byte. Update the CI pins and regenerate exports together when changing the generation version. + +`uv.lock` is authoritative. `just lock` regenerates it, the hash-pinned `requirements/*.txt` exports, and `packaging/flatpak/python3-dependencies.yaml`. The AppImage build installs from `runtime`/`vad` plus `appimage.txt`; `install.sh` consumes the runtime and selected extras with `--require-hashes --no-deps --no-build-isolation`, then installs the project with `--no-deps --no-build-isolation`. **Do not edit `requirements/*.txt` by hand**, nor the url/sha256 pairs in `packaging/flatpak/python3-dependencies.yaml`. Change `pyproject.toml` (or `requirements/whisper.in` for the Whisper engine, `requirements/appimage*.in` for the AppImage), run `just lock`, and commit the lock plus the exports with the manifest change. + +| Constraint | Rule | +|---|---| +| PyGObject | The runtime installer uses distro `python3-gi` via `--system-site-packages`; do not pip-install it into `venv/`. The dev `.venv/` instead builds the locked version with uv when glib 2.80+ and native headers are available. uv-managed interpreters do not see distro `gi` unless the venv is created with `--system-site-packages` | +| `[vosk]` extra | Wheel-only on PyPI (no sdist). Never part of a source-buildable lock. `install.sh --engine=vosk` installs it | +| Whisper CPU torch | `requirements/whisper.txt` is compiled from `requirements/whisper.in`. Pin `torch` to a `+cpu` local version — PyPI CUDA wheels win resolution regardless of index order. OpenAI Whisper does not use `torchaudio`, and the CPU index can lag torch | +| pywhispercpp | Pinned in `install.sh` as `PYWHISPERCPP_VERSION` (keep in sync with `uv.lock`) | +| Installer build tools | `[dependency-groups].installer-build` exports to `requirements/installer-build.txt`. Bootstrap uses hashed wheels on new and reused venvs; source builds use these tools without build isolation. Its setuptools `>=83` floor keeps the pinned installer tools patched; do not add it to `[build-system]` (Arch). Backend rebuilds select pywhispercpp's complete hash block from `runtime.txt` via `scripts/installer_requirements.py`, with `--no-deps` so they cannot replace the runtime | +| Release build tools | `[dependency-groups].release-build` exports to `requirements/release-build.txt`. `scripts/build_reproducible_wheel.py` builds in two fresh source trees/venvs with hashed tools and `--no-isolation`, compares wheel bytes, and stages only canonical distributions in `dist/`. These build-only venvs exclude system site-packages: host setuptools plugins must not influence locked builds, and packaging does not import GTK. Repeat runs clean recognized diagnostics and staged archives matching retained canonical digests; staged copies are deleted first so interrupted cleanup remains retryable. Unrelated/modified files are preserved and block cleanup. Never wipe all of `build/`. PR and release CI use Python 3.11 and pinned uv. Failed build outputs/logs stay under `build/reproducible-wheel/`, excluded from release artifacts | +| AUR source publication | Use the canonical release sdist, not a GitHub tag archive. `scripts/prepare_aur_source.py` (run with the locked `release-build` group) requires its published checksum and provenance from the exact release workflow/tag/commit before preparing a pinned PKGBUILD. Release CI builds/installs that unchanged recipe on current Arch; publication consumes only the gated artifact with `updpkgsums: false`. PR/local fixtures must explicitly use `--local-unattested` and are never publication inputs. `just aur-gate` keeps distributions, diagnostics and tooling in its own temporary directory, leaving shared packaging outputs and dev environments untouched; failures retain that directory and print its path. `vocalinux-bin` publication depends only on release creation and both AppImages, not the source gate or global checksums. Existing AUR provider stubs/pinned import smoke remain limited as documented in `docs/AUR.md` | +| Installer Whisper export | Compiled universally from Python 3.11, constrained by `runtime.txt` and `installer-build.txt` to keep shared pins consistent. Uses a `+cpu` torch pin and best-match index resolution so the CPU index's older copies of shared packages do not downgrade the runtime | +| Remote installer | After cloning, hand off to the tagged `install.sh` with the original arguments and remote venv path. The installer and its exports must come from the same revision, including when the tag predates the pinned installer | +| `[vad]` extra | `onnxruntime` for Silero VAD | +| One export per extra | Every extra in `pyproject.toml` needs a hash-pinned `requirements/.txt` (underscores become dashes), written by a `uv export` line in `just lock`. `install.sh` installs six of them, so an extra with no export is an install path with nothing pinned, which is how `[parakeet]`, `[faster_whisper]` and `[vosk]` reached users. `tests/test_dependency_exports.py` enumerates the extras and the installer's call sites rather than trusting the recipe to stay complete; `docs` is the one exemption and it carries its reason in `EXPORT_EXEMPT` | +| Exports match the lock | `just export-check` re-runs every `uv export` line in `just lock` and fails if a committed export is behind `uv.lock`. It reads those lines out of the recipe, so an export added there is checked without touching `scripts/check_exports.py`, and it runs under `UV_OFFLINE=1`: `uv export` reads the lock and nothing else. The lint job runs it, because an export named in the recipe and never regenerated is a snapshot, not a pin. `uv pip compile` targets are out of scope by design (they resolve against live indexes) | +| AppImage PyGObject | Pinned separately in `requirements/appimage.in`, and below 3.52: the AppImage bundles its own interpreter and builds PyGObject against the base image's girepository-1.0, while uv.lock's 3.56 needs girepository-2.0 (glib 2.80+) | +| AppImage build inputs | Base image, tooling, interpreter, shaderc and the Vulkan headers are pinned in `packaging/appimage/tool_checksums.txt`. Build with `just appimage` (docker) — building on the host ships the host's glibc, which is what kept the AppImage off Debian 12 | +| AppImage boot matrix | `packaging/appimage/boot-test.sh` runs the finished AppImage in distro containers, and the matrix in `unified-pipeline.yml` must keep distros both older and newer than the build image: the old ones prove the glibc floor, the new ones catch a bundle that breaks the host binaries it spawns. A distro added there needs its package recipe in the script — `tests/test_appimage_packaging.py` checks both | +| Native packages (.deb / .rpm) | Thin packages built by nfpm in the pinned Debian 12 image (`packaging/native/tool_checksums.txt` pins the image and the nfpm releases). Python, GTK and PyGObject come from the distro; only `pywhispercpp` and `pynput` are vendored under `/usr/lib/vocalinux/vendor` (unpackaged on Debian/Fedora). `packaging/native/smoke-test.sh` installs the package per-distro and runs `vocalinux --version` plus an import smoke — `tests/test_native_packaging.py` keeps the deps lists, vendored set and CI matrix consistent offline | +| Snap Python inputs | `snap/local/build.py` uses `requirements/installer-build.txt` in an isolated, build-only venv and installs `requirements/runtime.txt` with hashes, no dependency resolution or build isolation. The project installs without dependencies or index access; never strip PyGObject from `pyproject.toml`. GI comes from the GNOME extension. Keep portable CPU flags and force the pinned pywhispercpp sdist without a wheel cache. PR/release CI installs the real artifact via `snap/local/smoke-test.sh` before publication. Native Ubuntu/GNOME/Snapcraft inputs remain channel-controlled, not byte-for-byte reproducible — see `docs/SNAP.md` | +| Flatpak deps | `packaging/flatpak/python3-dependencies.yaml` is generated from `requirements/vad.txt` (runtime dependencies plus the `[vad]` extra) by `scripts/sync_flatpak_deps.py` (`just flatpak-deps`, which `just lock` runs itself). It resolves each artifact by the digest uv already recorded, so the Flatpak downloads the bytes in `uv.lock`; `onnxruntime` is pinned to CPython wheels for each Flatpak architecture and the GNOME 50 Python version. The project installs there with `pip3 install --no-deps`, so nothing inside the build evaluates `pyproject.toml` — `tests/test_flatpak_packaging.py` checks the invariant offline | +| Speech models | Verified against digests pinned in `src/vocalinux/utils/model_checksums.txt` before install, by both `install.sh` and the runtime downloaders. **Fails closed** — an unpinned model is refused. Regenerate with `just model-checksums` (never by hand); `tests/test_model_checksums.py` fails if it falls behind. whisper.cpp URLs use a pinned Hugging Face commit, never `main` | + +Optional extras: `vosk`, `whisper`, `vad`, `dev`. + +## Layout + +``` +src/vocalinux/ +├── main.py, version.py, common_types.py, dbus_service.py, post_processor.py +├── audio/ +│ ├── capture.py # PortAudio capture sources and device handling +│ ├── pipewire.py # PipeWire system-audio capture +│ └── playback_ducker.py # lower default sink while dictating +├── single_instance.py # $XDG_DATA_HOME/vocalinux/instance.lock +├── auto_pause_monitor.py # unload model while configured apps run +├── model_keepalive.py # idle unload +├── suspend_handler.py # logind PrepareForSleep +├── custom_dictionary.py # terms bias + transcript correction file contracts +├── gateway_embed/ # optional local VocaGateway lifecycle +├── speech_recognition/ +│ ├── recognition_manager.py # VAD, segmentation, and engine dispatch +│ ├── engines/ # engine implementations and availability +│ ├── command_processor.py # voice commands +│ ├── command_phrases.py # voice command phrases and localized forms +│ ├── diarization.py # TinyDiarize per-speaker file transcription (--transcribe-file / tray) +│ ├── silero_vad.py +│ └── data/ # bundled silero_vad.onnx +├── text_injection/ +│ ├── text_injector.py # DesktopEnvironment backend selection +│ ├── focused_window.py # focused application detection +│ ├── remote_desktop_portal.py # Wayland Remote Desktop Portal support +│ └── ibus_engine.py # Wayland IBus injection +├── ui/ +│ ├── tray_indicator.py, settings_dialog.py, settings_about.py +│ ├── settings_engines.py, first_run_dialog.py, dictation_overlay.py +│ ├── dictation_pad.py +│ ├── transcript_dialog.py # speaker-tagged transcript viewer/export +│ ├── config_manager.py, action_handler.py, audio_feedback.py +│ ├── autostart_manager.py, keyboard_shortcuts.py, notifications.py +│ ├── logging_dialog.py, logging_manager.py, transcription_history.py +│ └── keyboard_backends/ # pynput (X11), evdev (Wayland) +├── utils/ +│ ├── paths.py, resource_manager.py, host_process.py +│ ├── update_checker.py, update_monitor.py, gtk_color_scheme.py +│ ├── pywhispercpp_loader.py # bundled-lib preloader for source-built installs +│ └── whispercpp_model_info.py, vosk_model_info.py +└── resources/ # SVG icons + WAV cues (also repo resources/) +``` + +Also: `tests/`, `docs/`, `packaging/` (AppImage, AUR, Flatpak, native .deb/.rpm), `scripts/`, +`install.sh` (bootstrap and orchestration), `install.d/` (sourced installer modules), +`uninstall.sh`, `web/`. `scripts/distro-package-map.yaml` owns installer package +names; `install.d/package_map.sh` is generated by `just distro-packages`. + +| Task | Start here | +|---|---| +| Voice command | `speech_recognition/command_processor.py` | +| Engine / models | `speech_recognition/recognition_manager.py` | +| Text injection | `text_injection/text_injector.py`, `focused_window.py`, `remote_desktop_portal.py`, `ibus_engine.py` | +| Settings | `ui/config_manager.py`, `ui/settings_dialog.py` | +| Hotkeys | `ui/keyboard_shortcuts.py`, `ui/keyboard_backends/` | + +## Style + +- Type hints on all function signatures. `Protocol` interfaces live in `common_types.py` +- Imports: stdlib → third-party → local (`isort` black profile) +- Names: `PascalCase` classes, `snake_case` functions, `UPPER_SNAKE_CASE` constants, `_private` methods +- `logger = logging.getLogger(__name__)` per module +- Triple-quoted docstrings on modules, classes, and public functions +- Specific exceptions; log errors with context +- `subprocess` calls that run a **host** binary pass `env=host_env()` (`utils/host_process.py`): a host binary inheriting the AppImage's library paths dies on the wrong GLib.

By contrast, +our General Public Licenses are intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + Developers that use our General Public Licenses protect your rights +with two steps: (1) assert copyright on the software, and (2) offer +you this License which gives you legal permission to copy, distribute +and/or modify the software. + + A secondary benefit of defending all users' freedom is that +improvements made in alternate versions of the program, if they +receive widespread use, become available for other developers to +incorporate. Many developers of free software are heartened and +encouraged by the resulting cooperation. However, in the case of +software used on network servers, this result may fail to come about. +The GNU General Public License permits making a modified version and +letting the public access it on a server without ever releasing its +source code to the public. + + The GNU Affero General Public License is designed specifically to +ensure that, in such cases, the modified source code becomes available +to the community. It requires the operator of a network server to +provide the source code of the modified version running there to the +users of that server. Therefore, public use of a modified version, on +a publicly accessible server, gives the public access to the source +code of the modified version. + + An older license, called the Affero General Public License and +published by Affero, was designed to accomplish similar goals. This is +a different license, not a version of the Affero GPL, but Affero has +released a new version of the Affero GPL which permits relicensing under +this license. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU Affero General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Remote Network Interaction; Use with the GNU General Public License. + + Notwithstanding any other provision of this License, if you modify the +Program, your modified version must prominently offer all users +interacting with it remotely through a computer network (if your version +supports such interaction) an opportunity to receive the Corresponding +Source of your version by providing access to the Corresponding Source +from a network server at no charge, through some standard or customary +means of facilitating copying of software. This Corresponding Source +shall include the Corresponding Source for any work covered by version 3 +of the GNU General Public License that is incorporated pursuant to the +following paragraph. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the work with which it is combined will remain governed by version +3 of the GNU General Public License. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU Affero General Public License from time to time. Such new versions +will be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + + Each version is given a distinguishing version number. If the +Program specifies that a certain numbered version of the GNU Affero General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU Affero General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU Affero General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF +ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF +SUCH DAMAGES. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU Affero General Public License as published + by the Free Software Foundation, either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU Affero General Public License for more details. + + You should have received a copy of the GNU Affero General Public License + along with this program. If not, see . + +Also add information on how to contact you by electronic and paper mail. + + If your software can interact with users remotely through a computer +network, you should also make sure that it provides a way for users to +get its source. For example, if your program is a web application, its +interface could display a "Source" link that leads users to an archive +of the code. There are many ways you could offer source, and different +solutions will be better for different programs; see section 13 for the +specific requirements. + + You should also get your employer (if you work as a programmer) or school, +if any, to sign a "copyright disclaimer" for the program, if necessary. +For more information on this, and how to apply and follow the GNU AGPL, see +. diff --git a/MANIFEST.in b/MANIFEST.in new file mode 100644 index 0000000..88fc4f3 --- /dev/null +++ b/MANIFEST.in @@ -0,0 +1,4 @@ +include vocalinux.desktop +include resources/icons/scalable/*.svg +include resources/sounds/*.wav +recursive-include src/vocalinux/resources * diff --git a/README.md b/README.md index a3f50c0..acc93f6 100644 --- a/README.md +++ b/README.md @@ -1,16 +1,463 @@ -# ci-template +

+ +Vocalinux turns speech into typed text in whatever app has focus. It is a free, AGPL-3.0-licensed desktop app for X11 and Wayland. After you download a model, local engines (whisper.cpp by default, plus OpenAI Whisper, Faster Whisper, VOSK, and Parakeet) run speech-to-text on your machine. An optional remote HTTP API is off unless you configure it. + +No Voca account is required. Models download once. After that, speech-to-text stays on your machine. + +**Current release:** [v0.18.5](https://github.com/VocaHQ/vocalinux/releases/tag/v0.18.5). Patch: a stop that races a recording start can no longer leave the mic recording forever, keyboards stay alive through suspend and the GNOME lock screen, Ctrl+mouse-wheel zoom works again, Dictation Pad and Settings stop travelling workspaces together, paste-injection copies are marked sensitive for clipboard history on wl-clipboard 2.2+, and `install.sh` gains an upgrade mode that keeps your existing configuration.

Typical install time with whisper.cpp is about 1-2 minutes. + +| Engine | When to use | +|--------|-------------| +| **whisper.cpp** (default) | Best default; Vulkan GPU on AMD, Intel, and NVIDIA | +| **Whisper** (OpenAI) | PyTorch path; NVIDIA/CUDA | +| **Faster Whisper** | CPU-friendly Whisper via CTranslate2 / INT8 | +| **VOSK** | Low RAM / minimal footprint | +| **Parakeet** | CPU; NVIDIA NeMo ASR via sherpa-onnx; 25 European languages | +| **Remote API** | Offload to a server you configure | + +Non-interactive options: + +```bash +bash /tmp/vl.sh --auto # whisper.cpp defaults +bash /tmp/vl.sh --auto --engine=whisper # OpenAI Whisper +bash /tmp/vl.sh --auto --engine=faster_whisper # Faster Whisper (CPU) +bash /tmp/vl.sh --auto --engine=vosk # VOSK only +bash /tmp/vl.sh --auto --engine=parakeet # Parakeet (CPU) +``` + +For a specific release tag, see [GitHub Releases](https://github.com/VocaHQ/vocalinux/releases) or `./install.sh --tag=v0.18.5`. + +### Arch Linux (AUR) + +```bash +yay -S vocalinux +``` + +See [docs/AUR.md](docs/AUR.md). + +### AppImage + +Download the `x86_64` or `aarch64` AppImage from [Releases](https://github.com/VocaHQ/vocalinux/releases), mark it executable, and run it. Built against glibc 2.35 (Debian 12+, Ubuntu 22.04+, Fedora 36+, Arch, Tumbleweed). Host text-injection tools (`xdotool` on X11; `wtype` / `ydotool` / clipboard tools on Wayland) are still required. Current AppImages rebuild whisper.cpp with Vulkan and use the host GPU driver. Prefer the installer when you want system deps, a CUDA build, and models set up automatically. + +### Distro packages (.deb / .rpm) + +Download the `.deb` (Debian 12+, Ubuntu 24.04+) or `.rpm` (Fedora) matching your CPU from [Releases](https://github.com/VocaHQ/vocalinux/releases) and install with `sudo apt install ./vocalinux_*.deb` or `sudo dnf install ./vocalinux-*.rpm`. Thin packages: Python and GTK come from the distro. No auto-update; CPU whisper.cpp. Details in [docs/INSTALL.md](docs/INSTALL.md). + +### Flatpak (any distro) + +Install and auto-update via the self-hosted VocaHQ remote (`flatpak update` picks up each release): + +```bash +flatpak install https://vocahq.github.io/vocalinux-flatpak/com.vocalinux.Vocalinux.flatpakref +``` + +The `.flatpakref` adds the `vocahq` remote and resolves the GNOME runtime through Flathub.

The recipe ships **no `uinput` plug** and no ydotool; the Store denied the super-privileged grant, which held the 0.17.0+ revisions and left **v0.16.2 (rev 7)** on edge. On KDE Plasma, KWin's portal can mistype letter case ([KDE bug 489021](https://bugs.kde.org/show_bug.cgi?id=489021)); set Virtual Keyboard to "IBus Wayland" so dictation types correctly. + +GitHub `.snap` files through v0.18.2 declare `uinput`, so KDE users who want ydotool can sideload that build and connect the plug manually: + +```bash +sudo snap install --dangerous ./vocalinux_0.18.2_amd64.snap +sudo snap connect vocalinux:uinput # only in the v0.18.x sideload; the recipe no longer ships it +``` + +### Nix / NixOS (flake) + +```bash +nix run github:VocaHQ/vocalinux # try it +nix profile install github:VocaHQ/vocalinux +``` + +The flake also ships `nixosModules.vocalinux` and `homeManagerModules.vocalinux` for declarative installs (`programs.vocalinux.enable = true`). The bundled pywhispercpp builds with Vulkan GPU inference. Details: [packaging/nix/README.md](packaging/nix/README.md). + +### From source + +```bash +git clone https://github.com/VocaHQ/vocalinux.git +cd vocalinux +./install.sh +# or pick the engine up front +./install.sh --engine=whisper_cpp +./install.sh --engine=vosk +./install.sh --engine=parakeet --auto +``` + +### After installation + +```bash +vocalinux # if ~/.local/bin is on PATH +# or +~/.local/share/vocalinux/venv/bin/vocalinux +``` + +You can also launch Vocalinux from your application menu. + +### Nightly builds + +Daily builds from `main` appear on [Releases](https://github.com/VocaHQ/vocalinux/releases).

It uses Silero VAD when +available and amplitude thresholds otherwise, then places finalized segments +on a bounded queue. A recognition worker consumes the queue, dispatches each +segment to the selected engine, applies dictionary corrections and voice +command parsing, and invokes callbacks. + +The text callback submits work to one ordered post-processing worker. That +worker runs the configured post-processing script, then injects text or places +it in the in-app dictation pad. `TextInjector` selects a backend from the +detected `DesktopEnvironment`: X11 uses xdotool, Wayland can use wtype or +ydotool, and the IBus and Remote Desktop Portal paths support their respective +sessions. + +## Threads and state ownership + +- The GTK main thread owns widgets, dialog state, tray state, and the GLib main + loop.

Existing `dist/`, `build/reproducible-wheel/` and +the developer environment are untouched, so other packaging commands can run +before or after it. Successful runs clean the temporary directory; failed runs +retain it and print its path for diagnosis. + +### Release gate + +After the release checksum/provenance job succeeds, `aur-source-test` downloads +the **published** sdist and manifest, verifies them, and prepares the PKGBUILD. +The same Arch gate makes `makepkg` download the actual source URL afresh +(`AUR_FETCH_SOURCE=1`) and verify its checksum, runs `namcap` on the recipe and +package, installs the package, checks the installed distribution version, and +runs the import smoke. It does not rewrite the source URL or disable source +checksum checks. The tested recipe and downloaded archive must match the +prepared PKGBUILD and provenance-verified sdist byte-for-byte. + +Only after this succeeds is `aur-source-pkgbuild` uploaded for `publish-aur`. +Publication downloads that exact file; there is no version rewrite or +`updpkgsums` afterwards. The gate runs even without AUR credentials; only the +final push is secret-gated. This intentionally makes source publication wait +for the release's checksums and attestations. `vocalinux-bin` uses a separate +AppImage publication path independent of this source gate and the global +checksum job; its PR smoke still uses a stub AppImage. + +Both gates deliberately use rolling `archlinux:latest`: #757 was Arch's +setuptools moving underneath us. `python-pywhispercpp` (virtual, provided by the +AUR backends) and `python-pynput` (AUR) cannot come from the repos, so the gate +satisfies them with a stub for dependency resolution and pip-installs their +pinned versions from `requirements/runtime.txt` for the import smoke.

Inputs are normalized to NFC +for matching, so composed/decomposed accents are handled consistently. + +| Engine | Custom terms | Corrections | +| --- | --- | --- | +| OpenAI Whisper | `initial_prompt` | Yes | +| whisper.cpp | Advanced initial prompt followed by custom terms; explicit empty prompt clears reused native state | Yes | +| Faster Whisper | `initial_prompt` | Yes | +| VOSK | No prompt-bias API | Yes | +| Parakeet | No prompt-bias API | Yes | +| Remote API | No prompt is added to current request formats | Yes | + +`--dictionary-file PATH` preserves the #767 session-only behavior: `PATH` is +used as the custom terms file, it enables terms for that session, and Settings +does not modify the saved terms file or enablement. Corrections remain loaded +from the standard JSON file. The previous experimental #768 +`text_injection.custom_dictionary` config list is read only as a fallback until +the JSON corrections file exists; it is never silently deleted or migrated. + +The #767 persisted configuration keys are retained unchanged: +`dictionary.enabled`, `dictionary.file_path` (default +`~/.config/vocalinux/dictionary.txt`), and `dictionary.max_words`. Existing +Peony settings therefore continue to select the scanner's `dictionary.txt` +file. New configured paths are accepted only when they can be expanded and are +either absent (so the UI can create them) or readable regular files; a failed +save leaves the prior setting in place. Invalid configured and `--dictionary-file` +paths are safely ignored and shown as unavailable rather than raising. + +## Alternatives rejected + +- **One mixed line file:** cannot express arbitrary phrases and replacements + without reserving/escaping delimiters, which weakens the scanner contract. +- **Corrections in `config.json`:** makes a scanner compete with application + settings writes and offers no durable external-file schema. +- **Post-command correction:** allows command-like transcription errors to be + acted on before they can be fixed. +- **Automatically adding correction replacements to prompts:** rejected because + replacements are not automatically included in the recognition prompt; + corrections work post-transcription on every engine. + +## Human test checklist + +1. Add `VocaLinux`, `PyGObject`, and a non-ASCII term in **Custom terms**; + confirm `dictionary.txt` is UTF-8, one line per term, and an external + edit changes the next Whisper, whisper.cpp, and Faster Whisper dictation segment. +2. Add `super base` → `Supabase`; test lowercase, uppercase, punctuation, an + overlapping short correction, `C++`, and non-ASCII text. Confirm replacement + casing is exact and embedded text (for example `supersize`) is not replaced. +3. With voice commands enabled, add a correction that changes a command-like + misrecognition into ordinary text. Confirm it is injected rather than acted + on. Also verify an intentionally command-like replacement is avoided. +4. Edit each file externally while VocaLinux is running. Test an invalid JSON + correction file and invalid UTF-8 terms file; confirm dictation continues and + the Settings status/save feedback is clear. +5. Test the UI with keyboard only: Add buttons via Enter, empty validation, + update/remove feedback, narrow window, long entries, and high-contrast theme. +6. Test all engines: Whisper, whisper.cpp, and Faster Whisper should use terms and + corrections; VOSK, Parakeet, and remote API should use corrections only, with + the VOSK terms warning. +7. Start with `--dictionary-file /path/to/terms.txt`; confirm the session uses + that file, Settings disables terms editing, saved settings remain unchanged, + and corrections still apply. +8. Start with an unresolved path such as `--dictionary-file ~missing-user/terms.txt` + and configure an unreadable path through the file chooser. Confirm Settings + reports the path safely, dictation continues without terms, and the prior + saved `dictionary.file_path` remains intact. diff --git a/docs/DISTRO_COMPATIBILITY.md b/docs/DISTRO_COMPATIBILITY.md new file mode 100644 index 0000000..1d25ce6 --- /dev/null +++ b/docs/DISTRO_COMPATIBILITY.md @@ -0,0 +1,563 @@ +# Linux distribution compatibility + +How Vocalinux behaves across distributions, what is tested, and what to install manually when needed. + +For install steps, prefer [INSTALL.md](INSTALL.md).

The fine-grained PAT scoped to just that + repo is the recommended minimum; a broader classic PAT works too. +5. **Variables (optional)** — same settings page, Variables tab: + - `FLATPAK_REMOTE_REPO` — publish target (default + `VocaHQ/vocalinux-flatpak`) + - `FLATPAK_REMOTE_URL` — remote URL baked into the `.flatpakrepo` + (default `https://vocahq.github.io/vocalinux-flatpak/repo`; set + e.g. `https://flatpak.vocalinux.com/repo` for a custom domain) + - `FLATPAKREPO_URL` — where users fetch `vocahq.flatpakrepo` (default + `https://vocahq.github.io/vocalinux-flatpak/vocahq.flatpakrepo`) + - `FLATPAKREF_URL` — where users fetch the app `.flatpakref` (default + `https://vocahq.github.io/vocalinux-flatpak/com.vocalinux.Vocalinux.flatpakref`) +6. **Trigger** — push a stable `v*` tag (alpha/beta/rc tags do not publish to + the remote), or re-run `publish-flatpak-remote` on an existing release run + after configuring the secrets. + +Without the secrets the job skips itself (same pattern as `publish-aur`), so +an unconfigured remote never fails a release. + +## How a publish works + +`release.yml → publish-flatpak-remote` runs on stable tags only, after the +GitHub Release exists and the two arch builds finish: + +1. Downloads `Vocalinux--{x86_64,aarch64}.flatpak` from the build + jobs. +2. Probes the remote repo for an existing `gh-pages` branch; only a confirmed + first publish may skip the history checkout — a transient failure aborts + instead of seeding an empty repo over the live remote. It then checks out + `gh-pages` and copies `repo/` over, so existing objects and deltas + survive — clients pull an incremental delta each release, not the whole + app. +3. `flatpak build-import-bundle --gpg-sign` imports each bundle under the + signing key. +4. `flatpak build-update-repo --generate-static-deltas --gpg-sign + --gpg-import` rebuilds the summary, signs it, and generates static deltas. +5. Regenerates `vocahq.flatpakrepo` (URL + base64 public key), + `com.vocalinux.Vocalinux.flatpakref` (the one-command app ref carrying the + `RuntimeRepo=` pointer to Flathub), `vocahq.gpg` (the bare public key, for + the key-rotation path below), and the index page from + `packaging/flatpak/index.html`. +6. Publishes the directory back to `gh-pages` via + `peaceiris/actions-gh-pages`. + +## Verifying a publish + +```bash +flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo +flatpak remote-add --if-not-exists vocahq https://vocahq.github.io/vocalinux-flatpak/vocahq.flatpakrepo +flatpak remote-info vocahq com.vocalinux.Vocalinux # signed commit, both arches +flatpak install vocahq com.vocalinux.Vocalinux +flatpak run com.vocalinux.Vocalinux +# after the next tag: flatpak update pulls the delta +``` + +## Key rotation and loss + +Generate a fresh key, replace `FLATPAK_GPG_PRIVATE_KEY` (and +`FLATPAK_GPG_PASSPHRASE` if used), then re-run `publish-flatpak-remote`.

That path uses the same Remote API settings described below, with endpoint `/v1/audio/transcriptions`. It is **not** on-device recognition: audio goes to the gateway container on your machine. Details: [GATEWAY_EMBED.md](GATEWAY_EMBED.md). + +## How it works + +When the **Remote API** engine is active, Vocalinux: + +1. Captures microphone audio locally (16 kHz, mono, 16-bit PCM). +2. On end-of-utterance, packages the buffer as a WAV file in memory. +3. Uploads it using the configured HTTP format. +4. Reads the transcribed text from the JSON response and types it into the focused window. + +No audio is written to disk. VAD and segmentation stay local; only the heavy ASR step is remote. + +## Server-side setup + +You need a server that accepts audio uploads and returns text. Three common setups: + +### Option A: whisper.cpp server + +Build and run the bundled HTTP server from the [whisper.cpp](https://github.com/ggerganov/whisper.cpp) repo: + +```bash +git clone https://github.com/ggerganov/whisper.cpp +cd whisper.cpp +make server +./models/download-ggml-model.sh medium.en +./build/bin/whisper-server \ + --model models/ggml-medium.en.bin \ + --host 0.0.0.0 \ + --port 8080 +``` + +The server now listens on `http://:8080`.

Example with [Speaches](https://github.com/speaches-ai/speaches): + +```bash +docker run --rm -p 8000:8000 ghcr.io/speaches-ai/speaches:latest +``` + +The endpoint is `/v1/audio/transcriptions`. + +### Option C: FunASR/SenseVoice local server + +[FunASR](https://github.com/modelscope/FunASR) can run a local +OpenAI-compatible transcription service, which keeps audio on your own machine +or LAN while letting Vocalinux use SenseVoice or Paraformer-family models: + +```bash +pip install 'torch>=2.13.0' torchaudio +pip install funasr vllm fastapi uvicorn python-multipart +funasr-server --device cuda +``` + +The server listens on `http://localhost:8000` by default and exposes +`POST /v1/audio/transcriptions`.

A +remote GPU host works too: bind the server to the LAN interface, open the port, +and point Vocalinux at that host. + +### Network checklist + +- The server must be reachable from the client over HTTP or HTTPS. +- If you bind to `0.0.0.0`, open the port in your firewall (`ufw allow 8080/tcp`, etc.). +- For anything outside a trusted LAN, terminate TLS in front of the server (Caddy, nginx, Traefik) and require an API key. The audio you upload is private speech. +- If you also use the server from a mobile dictation app, terminate TLS even on a LAN. Most Android and iOS apps refuse cleartext HTTP. + +## Client-side setup (Vocalinux) + +### Via the Settings dialog + +The remote engine is a power-user option in the **Speech Engine** settings. + +1. Launch Vocalinux and open **Settings → Speech Engine → Remote Server**. +2. Toggle **Use remote server** on. This overrides whatever local engine is selected above it. +3. Fill in the fields: + - **Server URL**: base URL of the server, e.g. `http://192.168.1.100:8080` (no trailing slash needed; one is stripped automatically). + - **API Key** (optional): sent as `Authorization: Bearer `. Leave blank if your server doesn't require auth. + - **API Endpoint**: pick **Whisper.cpp (`/inference`)** or **OpenAI/FunASR (`/v1/audio/transcriptions`)** to match your server. + - **Model**: model identifier sent to OpenAI-compatible servers. Use `whisper-1` for classic Whisper servers, or `sensevoice` for FunASR/SenseVoice. +4. Click **Test Connection**. Success means the URL is reachable and credentials (if any) are accepted. A failure here is only a warning; Vocalinux will try again on the first transcription. + +Settings auto-save and re-initialise the engine immediately, so you can start dictating as soon as the test passes.

Older bases (RHEL 9, Debian 11, Ubuntu 20.04) are below that AppImage floor. The installer and PyPI package still require a distro that ships Python 3.11+, so they are not a workaround for Debian 11 or Ubuntu 20.04. + +Still needs host text-injection tools (`xdotool` on X11; `wtype` / `ydotool` / clipboard tools on Wayland). Current AppImages rebuild whisper.cpp with Vulkan and use the host GPU driver (`vulkaninfo --summary`). Prefer the installer when you want system deps, a CUDA build, and models set up automatically. + +## Distro packages (.deb / .rpm) + +From [GitHub Releases](https://github.com/VocaHQ/vocalinux/releases), pick the file matching your distro and CPU: + +```bash +# Debian / Ubuntu (amd64; arm64 files are attached too) +sudo apt install ./vocalinux_*_amd64.deb + +# Fedora (x86_64; aarch64 files are attached too) +sudo dnf install ./vocalinux-*.x86_64.rpm +``` + +These are thin packages: Python, GTK, PyGObject and the AppIndicator typelib come from the distribution, and `apt`/`dnf` resolves them. `xdotool`, `wtype`, `ydotool`, the clipboard tools and IBus are `Recommends`, matching the optional feature set of the other paths. Only `pywhispercpp` and `pynput` are vendored inside the package — `pywhispercpp` is packaged by neither distro and `pynput` is missing on Fedora. They land under `/usr/lib/vocalinux/vendor`, on `sys.path` via the `vocalinux` launcher. + +The `.deb` needs a distro that ships Python 3.11+: Debian 12+ and Ubuntu 24.04+ (Ubuntu 22.04 ships 3.10). whisper.cpp runs on CPU in these packages — the PyPI wheel, not the Vulkan build the AppImage carries. There is no auto-update: a new release is a new package install. A PPA and a COPR are not published yet. + +On Wayland, the default Right Alt shortcut reads keyboard devices through evdev, so your user needs `input` group membership or the hotkey is silently disabled: + +```bash +sudo usermod -aG input $USER # then log out and back in +``` + +Joining `input` grants read access to every keyboard and pointer device — X11 needs none of this.

It is **not on Flathub** (submission [flathub#9368](https://github.com/flathub/flathub/pull/9368) closed 2026-07-23 on policy grounds). Details: [packaging/flatpak/README.md](../packaging/flatpak/README.md). + +On native X11, hotkeys work without device access (GNOME X11 is the exception: +its X server hides physical keys from the X11 listener, so it also needs +`/dev/input`). On Wayland, the built-in hotkey needs `/dev/input` (`--device=input` on Flatpak 1.15.6 or newer, or +`--device=all` on older versions); otherwise enable External Activation and +bind a desktop shortcut to the D-Bus `Toggle` command in +[Running without device access](../packaging/flatpak/README.md#running-without-device-access). +Desktop shortcuts only toggle dictation, so they cannot support push-to-talk. + +## Snap (Ubuntu Snap Store) + +Listing: [snapcraft.io/vocalinux](https://snapcraft.io/vocalinux) (issue [#48](https://github.com/VocaHQ/vocalinux/issues/48)). Recipe: `snap/snapcraft.yaml`. Tagged `v*` releases attach `vocalinux__amd64.snap` to the GitHub Release and try Snap Store `edge` and `candidate` when credentials are set. `stable` is promoted from `candidate` after QA. + +Build inputs, the PR/release artifact gate, and its verification limits are +documented in [SNAP.md](SNAP.md). + +Store install, once Canonical lists the revision: + +```bash +sudo snap install vocalinux --edge +sudo snap connect vocalinux:audio-record # if mic is not auto-connected +sudo snap connect vocalinux:raw-input # global keyboard shortcuts (evdev) +sudo snap connect vocalinux:hardware-observe # list keyboards (/proc/bus/input/devices) +``` + +Native Wayland typing uses the RemoteDesktop portal: the compositor asks once on first dictation, nothing to connect. The recipe ships **no `uinput` plug** and no ydotool; the Store denied the super-privileged grant ([the request thread](https://forum.snapcraft.io/t/53528)), which held the 0.17.0+ revisions and left **v0.16.2 (rev 7)** on edge. On KDE Plasma, KWin's portal can mistype letter case ([KDE bug 489021](https://bugs.kde.org/show_bug.cgi?id=489021)); set Virtual Keyboard to "IBus Wayland" so dictation types correctly. + +Under strict confinement the snap reaches audio through the PulseAudio/PipeWire server, not the sound card, so Settings → Audio lists the server's microphones (via `pactl`) and records from the one you pick. whisper.cpp in the snap is built without a GPU backend and runs on the CPU, and host tools such as `nvidia-smi` and `vulkaninfo` are not visible inside it. For Vulkan acceleration use the [AppImage](#appimage) or the [installer](#recommended-installer) instead. + +GitHub `.snap` files through v0.18.2 declare `uinput`, so KDE users who want ydotool can sideload that build and connect the plug manually: + +```bash +sudo snap install --dangerous ./vocalinux_0.18.2_amd64.snap +sudo snap connect vocalinux:audio-record +sudo snap connect vocalinux:raw-input +sudo snap connect vocalinux:hardware-observe +sudo snap connect vocalinux:uinput # only in the v0.18.x sideload; the recipe no longer ships it +``` + +`--dangerous` is required because this file is not a Store revision and will not refresh from the Store; once the Store carries a newer revision, `sudo snap install vocalinux --edge` (or `snap refresh`) replaces it. + +## Nix / NixOS + +The repo is a flake: GTK, PyGObject and the AppIndicator typelib come from nixpkgs, and `pywhispercpp` (absent from nixpkgs, same gap as Debian and Fedora) is built from its vendored PyPI sdist. The wrapped binary carries every injector and clipboard tool on PATH. + +```bash +nix run github:VocaHQ/vocalinux # try it +nix profile install github:VocaHQ/vocalinux +``` + +On NixOS, `vocalinux.nixosModules.vocalinux` provides `programs.vocalinux.enable`, which installs the package and enables `hardware.uinput`. Add each dictating user to `input` and `uinput` for Wayland shortcuts and ydotool typing. Home Manager users get `vocalinux.homeManagerModules.vocalinux` with the same `programs.vocalinux` options — device permissions stay on the system side.

The one +exception is `snap-backfill.yml`: that workflow attaches the snap, rewrites +`SHA256SUMS`, and then runs `scripts/verify_release.py` itself. + +### Pre-publication wheel reproducibility + +PR CI and the release workflow run `scripts/build_reproducible_wheel.py` before +publication. It checks lock/export drift, installs the hash-pinned `release-build` +toolchain into two fresh virtualenvs without system site-packages, and independently +builds an sdist and its wheel in each source tree with `--no-isolation`. +`SOURCE_DATE_EPOCH` comes from +the checked-out commit. Both builds use the same Python 3.11 interpreter and +platform; this checks repeatability under controlled inputs, not cross-platform +or cross-Python-version reproducibility. Only wheels are compared byte-for-byte. + +Build-only environments deliberately exclude host packages and setuptools plugins. +Unlike runtime/development virtualenvs, they do not need distro PyGObject: the +backend reads version metadata without importing GTK. + +The script runs `twine check --strict` with the locked tools and stages only the +canonical wheel and sdist in `dist/` after comparison succeeds. All release +consumers reuse those distributions. Snap Store publication also waits for this +gate. Verification builds never enter the release checksum manifest. + +Locally, `PYTHON=python3.11 just reproducible-wheel` includes tracked working-tree +edits and non-ignored new files, but excludes ignored build/egg-info/venv state. +Repeat runs automatically clean the gate's previous logs and build archives. +Staged files in `dist/` are removed only if their names and digests match the +retained canonical archives. Unrelated or modified files, unexpected diagnostic +files, and symlinks cause cleanup to stop before deleting anything; move those +files aside first. The rest of `build/` is never cleaned. Logs, hashes and both +builds are retained in `build/reproducible-wheel/`; CI uploads that directory on failure. +Refresh the toolchain through `just lock`, not by editing its export by hand. +Cleanup removes staged copies before their canonical originals, so an interrupted +cleanup can safely be retried. +The gate holds a checkout lock from before cleanup through final staging; a second +active run fails without changing the first run's outputs. Archives are copied to +an ignored temporary sibling of `dist/` and then atomically renamed into place, +so interrupted staging leaves only complete archives in `dist/` and can be retried. + +### AUR source publication gate + +After `publish-checksums`, `aur-source-test` downloads the published canonical +sdist and `SHA256SUMS`. `scripts/prepare_aur_source.py` checks the digest and +cryptographically verifies provenance against this repository's release workflow, +tag ref and source commit before preparing the checksum-pinned PKGBUILD. +The exact prepared recipe is built, checked with namcap, installed and smoked on +current Arch. `publish-aur` downloads only that verified PKGBUILD artifact and +pushes it without further version/checksum rewrites (`updpkgsums: false`). + +This gate runs even without AUR publication credentials. Failure prevents the +AUR push, but does not unpublish GitHub/PyPI artifacts already released. It is +separate from PR/local `--local-unattested` fixtures, which exercise the same +preparation/build path but are never used for publication. See [AUR.md](AUR.md) +for the trust model and the existing AUR-provider smoke-test limitations. +`vocalinux-bin` publication waits only for release creation and both AppImages; +source-gate failures or unrelated checksum producers do not block it. + +## Detailed Release Steps + +### Step 1: Determine Version Number + +Follow semantic versioning: + +``` +Given version MAJOR.MINOR.PATCH-PHASE: + +MAJOR - Breaking changes (for 1.0.0: public API stable) +MINOR - New features, backwards compatible +PATCH - Bug fixes, backwards compatible +PHASE - alpha, beta, rc1, rc2, etc. (omit for stable releases) +``` + +**Examples:** +- Alpha → Beta: `0.4.1-alpha` → `0.5.0-beta` (new features, phase change) +- Beta → RC: `0.5.0-beta` → `0.5.0-rc1` (same features, testing phase) +- RC → Stable: `0.5.0-rc1` → `1.0.0` (first stable release) +- Stable patch: `1.0.0` → `1.0.1` (bug fixes only) +- Stable minor: `1.0.0` → `1.1.0` (new features) + +### Step 2: Update Core Version Files + +#### 2.1 Update `src/vocalinux/version.py` + +```python +__version__ = "0.5.0-beta" +__version_info__ = (0, 5, 0, "beta") +``` + +#### 2.2 Update `pyproject.toml` + +Change the Development Status classifier: + +```toml +# For Alpha: +"Development Status :: 3 - Alpha", + +# For Beta: +"Development Status :: 4 - Beta", + +# For Stable: +"Development Status :: 5 - Production/Stable", +``` + +### Patch releases within a minor line (e.g. 0.14.x) + +When shipping bug fixes only (PATCH bump, same MINOR): + +- **README / `docs/UPDATE.md` "What's New"** keeps the **minor-series feature list** (everything introduced in that 0.Y line) and adds a short **Bug fixes in this patch** subsection for the delta only. Do not make the marketing highlight table look featureless because this tag only contains fixes. +- **Website changelog** (`web/src/app/changelog/page.tsx`) may list only the delta for the new entry; older entries stay historical. +- **AppStream** (`packaging/flatpak/com.vocalinux.Vocalinux.metainfo.xml`): add a short `` note for the patch delta only; leave the long product feature `
    ` as series/product-level. +- **SECURITY.md** supported versions table usually stays on the minor line (`0.14.x`) without a row per patch. +- **AUR source PKGBUILD**: the release gate prepares `pkgver`, `_tag`, the normalized `_version`, and the canonical sdist digest, then tests that exact file. Do not introduce `SKIP` or rehash it during publication. The separate `vocalinux-bin` path still pins both AppImage digests before its own publication. +- **Dates**: patch release dates must not predate the previous release in changelog / AppStream / version history. + +### GitHub Release Notes Writing Rules + +Use these rules for every GitHub Release body (and for the draft pasted into the release-prep PR).

Dictation gains per-language shortcuts, a tray history menu, a floating overlay, and audio ducking.

Install first: [INSTALL.md](INSTALL.md). + +## Getting started + +1. Launch Vocalinux (`vocalinux` or the application menu) +2. Find the microphone icon in the system tray +3. Start dictation with the tray menu or your keyboard shortcut +4. Speak into the focused application; text is injected when an utterance completes +5. Stop by releasing the key (push-to-talk, default on new installs) or with the same shortcut (toggle) + +### Start on login + +Enable **Start on Login** from the first-run dialog, tray menu, or Settings. Vocalinux writes an XDG autostart entry (`~/.config/autostart/vocalinux.desktop`) and starts as a normal user app (`--start-minimized`). It does not create a systemd service. + +Works on common desktop environments (GNOME, KDE, Xfce, Cinnamon, MATE, LXQt). Minimal window-manager sessions may need their own autostart helper. + +### Status icons + +| Icon state | Meaning | +|------------|---------| +| Gray (off) | Inactive | +| Blue (on) | Listening | +| Orange | Processing speech | + +### Dictation formatting + +Vocalinux capitalizes the start of dictation and letters after `.`, `!`, or `?`. Each completed utterance leaves a trailing space so the next session does not glue onto the previous sentence. + +### Dictating into terminals + +When Vocalinux injects through the clipboard (the usual Wayland / ydotool path), it sends **Ctrl+V** in ordinary text fields and **Ctrl+Shift+V** in terminal emulator windows. Auto-detect works on X11 and on Hyprland, Sway, and niri. On GNOME or KDE Wayland, set **Settings → Dictation → Clipboard Paste Shortcut** to **Ctrl+Shift+V**. + +On non-US layouts such as German Neo, that chord uses the key that types **v** on the active layout (not physical KEY_V). Nested terminal panels inside an IDE are often invisible to window-class detection. If paste lands as a literal `^V` or does nothing, open **Settings → Dictation → Clipboard Paste Shortcut** and choose **Ctrl+Shift+V**. + +On X11, **Paste long dictations** opts in to clipboard-pasting dictations of 30 or more characters instead of typing them key by key. It is off by default. Vocalinux restores the previous clipboard contents after pasting unless **Copy to Clipboard** is enabled. If the clipboard contains an image or other non-text content, Vocalinux types the dictation and leaves that content alone. + +The clipboard copy behind these pastes is temporary: your previous clipboard comes back right after. When the copy goes through `wl-copy` 2.2 or newer, it is also marked sensitive (`wl-copy --sensitive`), and clipboard managers that honor that hint, such as Klipper or cliphist, keep it out of their history. Older `wl-copy` builds and X11 or XWayland pastes (`xclip`/`xsel`) have no such hint, so there the dictated text can still show up in history. With **Settings → Dictation → Copy to Clipboard** on, the dictated text is an ordinary copy and stays in history. + +**Other audio.** Settings → Audio → Other audio can lower speakers and headphones while the microphone is open, then put that volume back. It stays off until you turn it on. Level while dictating is a percent of the current volume (0 is silent). Quitting mid-dictation puts the volume back; if the app crashes first, the next launch does. + +## Audio input + +Open **Settings → Audio → Input Device** to select a specific microphone or choose +**System Default**. A valid explicit microphone selection uses that device and +bypasses the System Default preference below. + +With **System Default**, Vocalinux leaves valid default or virtual inputs under +the audio system's control rather than pinning a hardware device. + +On ALSA only, if PortAudio substitutes arbitrary hardware for the default input, +Vocalinux prefers an input-capable `pulse` PCM on the same host API to follow the +microphone selected in desktop sound settings. If no suitable `pulse` PCM exists, +it keeps PortAudio's fallback device and logs a warning. + +## Shortcuts + +Configure under **Settings → Shortcuts**: + +| Mode | Behavior | +|------|----------| +| **Push-to-talk** (default on new installs) | Hold Right Alt (Option on Mac-layout keyboards) while speaking; release to stop | +| **Toggle** | Double-tap the configured shortcut key to start/stop | + +Existing configs keep their saved shortcut. Left/right modifier keys and custom modifier+key combos (for example `Alt+R`) are supported. + +Enable **Pass Shortcut Keys to Applications** under **Settings → Dictation → Keyboard Shortcuts** to keep modifier actions such as Ctrl+mouse-wheel zoom working. Dictation still detects the configured shortcut, but the shortcut keys will also reach the foreground app, which may respond to them. This is off by default. + +## Voice commands + +Optional spoken commands for punctuation and editing (can be disabled in Settings). +English phrases always work. With a non-English recognition language, matching +punctuation and line-break phrases in that language are also recognized +(Italian *virgola* / *punto*, French *virgule* / *point*, and similar). + +| Command | Action | +|---------|--------| +| "new line" / "new paragraph" | Line break | +| "period" / "full stop" / "dot" | `.` | +| "comma" | `,` | +| "question mark" | `?` | +| "exclamation point" / "exclamation mark" | `!` | +| "semicolon" | `;` | +| "colon" | `:` | +| "delete that" / "scratch that" | Delete last sentence | +| "capitalize" / "uppercase" | Capitalize next word | +| "all caps" | Next word in ALL CAPS | + +Editing and formatting action phrases (`delete that`, `undo`, `capitalize`, and similar) +are currently English-only. + +## Engines and models + +Open **Settings → Speech Model**.

The default bundle is **v3-european** (25 European languages). **v2-english** is English-only. Parakeet ignores the catalog language picker (language is treated as auto). + +### Language + +Pick the language you dictate in from **Language**, or leave it on auto-detect. + +If you work in more than one language and switch keyboard layouts to do it, turn +on **Follow keyboard layout** instead. Vocalinux then reads your active layout at +the start of every dictation and uses the matching language, so switching layout +switches dictation language with it. The Language picker greys out while this is +on and shows what your current layout resolves to; turning it off pins that +language. + +Available for whisper.cpp, Whisper, Faster Whisper, and Remote API. VOSK loads a +separate model per language, so following a layout would mean a model reload on +the hotkey; Parakeet does not use the language picker at all. Active-layout +detection uses GNOME's input-source settings; on other desktops it falls back to +the configured primary layout. + +### Activation via a KDE Plasma global shortcut + +Instead of the built-in hotkey listener, you can let your desktop's global +shortcut system trigger Vocalinux. On Wayland the built-in listener reads +`/dev/input` (requiring membership in the `input` group and effectively acting +as a system-wide key reader). Delegating activation to the compositor avoids +this entirely: no `/dev/input` access and no `input` group needed just to +start/stop dictation. Text injection is unaffected. + +Enable it in Vocalinux: + +1. Open **Settings → Shortcuts** (the Keyboard Shortcuts group on the Dictation page) +2. Turn on **External Activation (Desktop Shortcut)** + +The change applies immediately; you do not need to restart. The built-in key +listener stops, and a running instance exposes a D-Bus service on the session +bus (`com.vocalinux.Vocalinux`). The CLI can forward commands to it: + +```bash +vocalinux --toggle # start if idle, stop if active +vocalinux --start # start voice typing +vocalinux --stop # stop voice typing +``` + +Then bind a compositor shortcut to `vocalinux --toggle` on a native install. +For Flatpak, bind the `gdbus` command in +[Running without device access](../packaging/flatpak/README.md#running-without-device-access) +instead, because `vocalinux --toggle` is not on the host PATH. A desktop +shortcut only sends the key press, so it can toggle dictation but cannot +support push-to-talk because it never sees the release. On KDE Plasma: + +1. Open **System Settings -> Keyboard -> Shortcuts -> Add New -> Command or Script** + (older Plasma: **System Settings -> Shortcuts -> Custom Shortcuts -> Edit -> + New -> Global Shortcut -> Command/URL**). + +2. Bind a key combination of your choice to the command `vocalinux --toggle` + for a native install. For Flatpak, use the D-Bus command linked above. + +Now your chosen key combination toggles dictation, handled by the compositor +rather than by Vocalinux reading the keyboard directly. This works the same way +on other compositors that support binding a key to a command (e.g. GNOME custom +shortcuts, Sway/Hyprland `bindsym`/`bind`). + +As an advanced alternative, you can set the same option in +`~/.config/vocalinux/config.json` under `shortcuts`: + +```json +"shortcuts": { + "disable_internal_hotkey": true +} +``` + +Quit Vocalinux before editing that file so the running app cannot overwrite +the edit from its cached config. Start Vocalinux again after saving. + +### Model size (whisper.cpp / Whisper) + +| Size | Approx. size | Tradeoff | +|------|--------------|----------| +| tiny | ~74MB | Fastest; real-time friendly | +| base | ~141MB | Balance of speed and accuracy | +| small | ~465MB | Better accuracy | +| medium | ~1.5GB | High accuracy | +| large | ~3.0GB | Best accuracy; heavier | + +For whisper.cpp, also pick a **Specialization**: standard multilingual, English-only, quantized (lower memory), Turbo, or legacy large. English-only specializations limit the language selector to English. Exact IDs (for example `medium.en-q5_0`, `large-v3-turbo`) work with `--model`. + +### Removing unused models + +If leftover files are on disk that are not the model currently selected, **Unused downloads** appears under the model info card. Expand it to delete leftovers one at a time. Confirming removes those files from `~/.local/share/vocalinux`. Packaged system-wide VOSK models are left alone. + +### GPU + +whisper.cpp prefers Vulkan when the bundled pywhispercpp libraries include it, then CUDA, then CPU. Host tools such as `vulkaninfo` only describe the machine. The engine follows the libraries actually loaded. On multi-GPU machines a discrete Vulkan device is preferred; override under **Settings → Performance → Vulkan GPU**. Check logs with `vocalinux --debug`. + +Pip wheels of pywhispercpp are often CUDA builds. In that case Vocalinux uses CUDA device 0. `install.sh` rebuilds pywhispercpp with Vulkan or CUDA when it can. + +### Auto-pause and keep-alive + +Under Settings: + +- **Auto-pause apps**: unload the model while listed apps run +- **Model keep-alive**: unload after idle timeout to free GPU/CPU + +In **Settings → Performance → Unload When Idle**, enable **Record while model +reloads** to speak as soon as you press the dictation shortcut. Audio stays in +memory while the model loads, then joins the rest of the recording for +transcription. Releasing the shortcut before loading finishes still submits the +recorded speech. Wait for that transcription to finish before starting another +recording. This option is off by default. + +## Tips for better recognition + +1.

Blank lines and `#` comments are allowed, so the same + file remains friendly to an accessibility scanner. Use the add/remove editor + or choose a different readable terms file with the file picker. +- **Transcript corrections** replace a known misheard word or phrase after + transcription, for example `super base` with `Supabase`. Corrections are + stored separately in `~/.config/vocalinux/custom-dictionary-corrections.json`. + +VocaLinux re-reads both files before each completed dictation segment, so an +external edit applies to the next segment without restarting the app. Vocabulary +bias works with Whisper, whisper.cpp, and Faster Whisper. Corrections work with +every engine, including VOSK, Parakeet, and the configured remote API. + +Corrections run before voice-command interpretation. This can prevent a +command-like misrecognition from acting, but avoid replacements that create a +voice command unless that is intentional. Correction replacements are not +automatically added to recognition bias. + +For a one-session terms override, start Vocalinux with: + +```bash +vocalinux --dictionary-file /path/to/dictionary.txt +``` + +This temporarily enables terms from that file without changing saved settings; +the Custom terms controls are disabled for the session. It does not disable +transcript corrections. + +`--transcribe-file` uses the TinyDiarize model (`small.en-tdrz`) and needs it downloaded first — the tray "Transcribe Audio File…" entry fetches it on demand. + +### Post-Processing + +Vocalinux can pipe each transcription result through a user-defined script before injecting it into your application.

Help channels: [SUPPORT.md](../SUPPORT.md). + +### Text injection backend + +Vocalinux types your dictated text using one of several backends. It picks one +automatically, and on most desktops the automatic choice is correct. + +Autodetection can be wrong, though, and it fails in a way that is easy to +misread: on a compositor that does not relay IBus commits to native Wayland +applications, IBus reports the text as delivered while nothing appears. If +dictation works in some windows (typically XWayland ones, like a browser) but +silently does nothing in others, that is the symptom. + +Pin the backend explicitly in `~/.config/vocalinux/config.json`: + +```json +{ + "text_injection": { + "backend": "wtype" + } +} +``` + +| Value | Backend | +|---|---| +| `auto` | Autodetect (default; autodetection may select IBus) | +| `ibus` | IBus input method; on Wayland, bypasses compositor checks and may silently do nothing in native Wayland apps | +| `portal` | RemoteDesktop portal (Wayland; the sandboxed path, asks for permission once, works under Flatpak and Snap) | +| `wtype` | wtype virtual keyboard (Wayland) | +| `ydotool` | ydotool uinput (Wayland; needs `ydotoold`) | +| `xdotool` | xdotool (X11). On Wayland it only turns IBus off -- the Wayland tool is still picked automatically | + +The setting takes effect on the next start. `auto` leaves normal autodetection +in place and may select IBus. An explicit non-IBus pin (`portal`, `wtype`, +`ydotool`, or `xdotool`) skips IBus selection. + +On Wayland, when IBus is not selected, autodetection tries the RemoteDesktop +portal first -- it is the only injection path Wayland officially supports and +it needs no uinput device or helper daemon -- then `ydotool`, `wtype`, and +finally `xdotool` under XWayland. + +On X11 the injection tool is `xdotool` regardless of which non-`ibus` value you +pin, so `xdotool` is the name to use there when IBus is unreliable in a +particular application. Pinning `ibus` keeps the IBus path; pinning anything +else turns it off. + +To try a backend for a single run without changing the saved setting, set +`VOCALINUX_FORCE_BACKEND`, which overrides the config value. Set it to `auto` +to ignore a saved pin for that run: + +```bash +VOCALINUX_FORCE_BACKEND=wtype vocalinux --debug +``` + +The setting and environment override are read at startup, so restart Vocalinux +after editing `config.json`. The startup log first records a backend pin request; +it does not prove the backend was available or that text reached the focused +application. Later logs identify a fallback when a pin was not applied. + +If a pinned tool is unavailable, Vocalinux warns and continues with its normal +fallback selection. `portal` needs a desktop implementing the +`org.freedesktop.portal.RemoteDesktop` interface (GNOME and KDE Plasma do; +most wlroots compositors do not). `ydotool` also needs a usable `/dev/uinput` +and a working `ydotoold` setup. `xdotool` types into X11/XWayland windows, +not native Wayland windows. A live test in the target application is still the +final confirmation that text is delivered. diff --git a/docs/agents/domain.md b/docs/agents/domain.md new file mode 100644 index 0000000..4032de0 --- /dev/null +++ b/docs/agents/domain.md @@ -0,0 +1,51 @@ +# Domain Docs + +How the engineering skills should consume this repo's domain documentation when exploring the codebase. + +## Before exploring, read these + +- **`GLOSSARY.md`** at the repo root, or +- **`GLOSSARY-MAP.md`** at the repo root if it exists: it points at one `GLOSSARY.md` per context.

By contrast, +our General Public Licenses are intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + Developers that use our General Public Licenses protect your rights +with two steps: (1) assert copyright on the software, and (2) offer +you this License which gives you legal permission to copy, distribute +and/or modify the software. + + A secondary benefit of defending all users' freedom is that +improvements made in alternate versions of the program, if they +receive widespread use, become available for other developers to +incorporate. Many developers of free software are heartened and +encouraged by the resulting cooperation. However, in the case of +software used on network servers, this result may fail to come about. +The GNU General Public License permits making a modified version and +letting the public access it on a server without ever releasing its +source code to the public. + + The GNU Affero General Public License is designed specifically to +ensure that, in such cases, the modified source code becomes available +to the community. It requires the operator of a network server to +provide the source code of the modified version running there to the +users of that server. Therefore, public use of a modified version, on +a publicly accessible server, gives the public access to the source +code of the modified version. + + An older license, called the Affero General Public License and +published by Affero, was designed to accomplish similar goals. This is +a different license, not a version of the Affero GPL, but Affero has +released a new version of the Affero GPL which permits relicensing under +this license. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU Affero General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Remote Network Interaction; Use with the GNU General Public License. + + Notwithstanding any other provision of this License, if you modify the +Program, your modified version must prominently offer all users +interacting with it remotely through a computer network (if your version +supports such interaction) an opportunity to receive the Corresponding +Source of your version by providing access to the Corresponding Source +from a network server at no charge, through some standard or customary +means of facilitating copying of software. This Corresponding Source +shall include the Corresponding Source for any work covered by version 3 +of the GNU General Public License that is incorporated pursuant to the +following paragraph. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the work with which it is combined will remain governed by version +3 of the GNU General Public License. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU Affero General Public License from time to time. Such new versions +will be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + + Each version is given a distinguishing version number. If the +Program specifies that a certain numbered version of the GNU Affero General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU Affero General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU Affero General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF +ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF +SUCH DAMAGES. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU Affero General Public License as published + by the Free Software Foundation, either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU Affero General Public License for more details. + + You should have received a copy of the GNU Affero General Public License + along with this program. If not, see . + +Also add information on how to contact you by electronic and paper mail. + + If your software can interact with users remotely through a computer +network, you should also make sure that it provides a way for users to +get its source. For example, if your program is a web application, its +interface could display a "Source" link that leads users to an archive +of the code. There are many ways you could offer source, and different +solutions will be better for different programs; see section 13 for the +specific requirements. + + You should also get your employer (if you work as a programmer) or school, +if any, to sign a "copyright disclaimer" for the program, if necessary. +For more information on this, and how to apply and follow the GNU AGPL, see +. diff --git a/packaging/aur/vocalinux-bin/PKGBUILD b/packaging/aur/vocalinux-bin/PKGBUILD new file mode 100644 index 0000000..1316cdd --- /dev/null +++ b/packaging/aur/vocalinux-bin/PKGBUILD @@ -0,0 +1,61 @@ +# Maintainer: Jatin K Malik +# Updated by .github/workflows/release.yml on v* tags.

Local `flatpak-builder` remains for +contributors (below). + +## Current Scope + +The manifest ships the default `whisper_cpp` engine and Silero VAD +(`onnxruntime`). VOSK is omitted because the PyPI package is wheel-only (no +sdist), so a Flathub-ready VOSK build would need to compile VOSK and its native +deps from source. + +Global keyboard shortcuts use **evdev** (`/dev/input`) on Wayland and +XWayland. On native X11, they use the X11 **pynput** listener through +`--socket=x11`. GNOME X11 prefers evdev and falls back to pynput when +`/dev/input` cannot be read. +Text injection prefers the **RemoteDesktop portal** +(`org.freedesktop.portal.RemoteDesktop` `NotifyKeyboardKeysym` sends keysyms, +so non-US layouts work) and falls back to **wl-copy** + **ydotool Ctrl+V** +(instant paste into native Wayland apps) when the portal is unavailable. +Character-by-character `ydotool type` is only a fallback. `xdotool` remains +for pure X11/XWayland clients. + +Permissions: `--socket=wayland` (clipboard), `--socket=x11` (xdotool fallback), +`--device=all` (evdev hotkeys + uinput for the ydotool fallback; Flatpak has +no narrower uinput flag). + +## Running without device access + +To disable device access while keeping GPU support for Vulkan whisper.cpp, run: + +```bash +flatpak override --user --nodevice=all --device=dri com.vocalinux.Vocalinux +``` + +On native X11, hotkeys still work through the X11 listener, except on GNOME X11, +where mutter never passes physical keys to that listener (#954), so it needs +`/dev/input` like Wayland. On Wayland, the built-in hotkey needs `/dev/input`: grant `--device=input` on Flatpak 1.15.6 or +newer, or `--device=all` on older versions. If `/dev/input` is unavailable, +enable **Settings → Shortcuts → External Activation (Desktop Shortcut)** and +bind a desktop shortcut to: + +```bash +gdbus call --session --dest com.vocalinux.Vocalinux --object-path /com/vocalinux/Vocalinux --method com.vocalinux.Vocalinux.Toggle +``` + +Use toggle mode for this shortcut. A desktop shortcut only sends a key press, +so it cannot support push-to-talk. Running +`flatpak run com.vocalinux.Vocalinux --toggle` also works, but starts a sandbox +on each press. The host `gdbus` command is immediate and does not start another +sandbox. + +Without `/dev/uinput`, the ydotool injection fallback is unavailable.

Refresh it whenever the dependency +set changes: + +```bash +just flatpak-deps # rewrite the manifest (needs PyPI) +just flatpak-deps-check # report drift, change nothing +``` + +`just lock` runs the first of those itself, so a normal dependency change needs +no extra step. + +The script resolves each package's URL by looking up the digest uv already +recorded, so the bytes this build downloads are the bytes in `uv.lock`, not +merely the same version number. It takes a universal wheel where one exists and +the sdist otherwise. `onnxruntime` has no sdist, so its CPython-ABI wheel is +pinned to GNOME 50's Python version and selected separately for each Flatpak +architecture. + +This replaced a `flatpak-pip-generator` invocation whose package list was typed +out on the command line. Nothing regenerated it and no test compared it to +anything, so it drifted: by 2026-09-10 ten of its fifteen shared packages were +behind the lock, `pydub` and `lxml` were still built four months after #705 +deleted them for having no imports, and pywhispercpp sat at 1.4.1 under the +project's own `>=1.5.0`. The project is installed here with +`pip3 install --no-deps`, so nothing inside the build could notice. +`tests/test_flatpak_packaging.py` is what notices now, and it runs offline. + +Two things in that file are hand-written and the script preserves them, because +no generator produces them: pywhispercpp's Vulkan build, which injects a version +into `setup.py` (the sdist ships no `version.txt`, `setup()` takes no `version=` +argument, and setuptools-scm has no git tree to read in the sandbox), and the +symlinking of whisper.cpp's shared libraries onto the loader path. + +`python3-build-dependencies.yaml` is a small hand-maintained helper so +`--no-build-isolation` builds can import `mesonpy` before NumPy is built. + +## Channel: VocaHQ remote + GitHub Releases, not Flathub + +Flathub is **not pursued**.

    Patch: a stop that races a recording start can no longer leave the microphone recording forever, capture reads happen outside the buffer lock so a stalled microphone can no longer hang Stop, keyboards stay alive through suspend and the GNOME lock screen, Dictation Pad and Settings no longer bind to other windows on Wayland, Ctrl+mouse-wheel zoom works again, the installer gains an upgrade mode that keeps your existing configuration, and paste-injection copies are marked sensitive for clipboard history on wl-clipboard 2.2+. This Flatpak still ships whisper.cpp only.

    +     +     + + +

    Patch: long push-to-talk dictations are transcribed in segments instead of being cut off, model downloads only start after you confirm them and Cancel cancels the whole change, Test Dictation keeps its own result while the Dictation Pad is open, the GPU picker follows ggml's device list and CPU runs use most of your cores, the recording hotkey can cancel a transcription in progress, this Flatpak bundles onnxruntime for Silero VAD and uses the X11 hotkey listener on X11 sessions, RemoteDesktop portal requests no longer collide on GNOME, update checks can be turned off, and Slovenian is supported. This Flatpak still ships whisper.cpp only.

    +     +     + + +

    Patch: "new line" and "new paragraph" voice commands insert real line breaks standalone and mid-utterance, hotkeys work again on GNOME Shell X11 and quitting no longer collapses multi-layout keyboard maps, the bundled pywhispercpp builds at the portable x86-64 baseline so older CPUs stop crashing, and the Snap recipe drops the `uinput` plug the Store denied so revisions publish again. This Flatpak still ships whisper.cpp only.

    +     +     + + +

    Patch: the dictation overlay orb pulses and ripples with live microphone level, Nix gets a flake package with NixOS and Home Manager modules plus Vulkan GPU inference, keyboards with a held key or queued key events are left ungrabbed at startup so typing during launch cannot strand a key, bundled pywhispercpp drops -march=native so AppImage and Flatpak stop crashing on older CPUs, and the piped installer prompts via /dev/tty. This Flatpak still ships whisper.cpp only.

    +     +     + + +

    Patch: Settings Proxy page for model downloads and update checks behind SOCKS5/HTTP proxies, opt-in JSONL transcript persistence so a failed injection no longer loses the text, .deb and .rpm release packages for Debian and Fedora, and a slimmer tray menu with Start on Login and About living in Settings. Dictation pad windows no longer ghost away under Wayland compositors, keyboard discovery stops grabbing mice, touchpads, and power buttons, KDE Plasma 6 Wayland letter case is fixed, and the Speech Model picker stages changes until Download is confirmed instead of starting a fetch per click. This Flatpak still ships whisper.cpp only.

    +     +     + + +

    Minor: in-app Dictation Pad for Wayland-safe dictation, per-language dictation shortcuts, tray dictation history, file transcription with speaker labels, opt-in D-Bus activation for compositor global shortcuts, custom dictionary with corrections, postprocessing script hook, floating dictation overlay, audio ducking while dictating, and the dictation hotkey grabbed so it stops leaking into the focused app. PipeWire/system-audio capture and the RemoteDesktop portal injection backend are native-install paths; this Flatpak still ships whisper.cpp only.

    +     +     + + +

    Minor: Faster Whisper and Parakeet local engines, Speech Model simple setup, first-run system language, searchable open language picker, localized punctuation commands, bare function-key push-to-talk, Snap packaging with ydotool/uinput, Flatpak bundles attached by the release workflow, and XWayland/layout paste plus settings/audio fixes (HDA analog mics at native layout, native GTK OS dark/light, English-only models no longer trap other languages). This Flatpak still ships whisper.cpp only.

    +     +     + + +

    Stability patch: skip leftover IBus on KDE so dictation types into real apps, Wayland/IBus shortcuts via wtype and ydotool, real BackSpace for "delete that", Fedora/Arch installer glslc (not glslang), nightly version stamp before build, release integrity checksums and pinned builders, AUR PKGBUILD CI gate, distro CI plus docs drift fixes, and VocaGateway Beta on the site.

    +     +     + + +

    Stability patch: per-engine model size at startup, save the model only after it loaded, leftover-download list shows every row, one ConfigManager so Settings writes stick, tray stays idle after leftover transcription and can download the recommended model from the missing-model notification, Ctrl+Shift+V paste in terminals, GNOME XWayland layout after scoped IBus inject, Python 3.11 installer floor with verified model downloads, AppImage glibc that boots on Debian 12, AUR build against Arch extra setuptools 84, skip context_params on AUR pywhispercpp 1.4, and Settings/About layout polish.

    +     +     + + +

    In-app update checker with tray notifications, hold Right Alt push-to-talk default for new installs, searchable language list, delete unused downloaded speech models, family dictation tone picker (default Voca, family preview WAVs), Settings About page for this app, VocaHQ, and talk to us, AGPL-3.0 relicensing, shared Voca family mic for app/tray/site icons, hardened installer with Justfile and uv lockfiles (distro python3-gi required), Test Dictation missing-model message, and desktop reliability fixes for IBus, audio capture, clipboard restore, GPU/Vulkan selection, and AppImage GI typelibs.

    +     +     + + +

    Searchable sidebar settings with dictation controls in the sidebar footer, AppImage packages for x86_64 and aarch64, expanded speech-language catalog (including Hungarian), sentence capitalization and trailing spaces for continuous dictation, auto-pause and idle model unload, Vulkan discrete-GPU selection, ibus-wayland support on previously unbridged compositors, Bluetooth mic capture crash fix, custom-shortcut Record/Set restore, and desktop reliability fixes.

    +     +     + + +

    IBus stability (engine process launch after XDG path import; first-dictation FocusIn gate on GNOME Wayland) and settings dialog tabs that scroll so the window fits the monitor.

    +     +     + + +

    First Flathub-oriented packaging release: Flatpak with whisper.cpp + Vulkan, wl-copy/ydotool Wayland paste, evdev global hotkeys, AUR package, layout-aware shortcuts, and installer fixes.

    +     +     + + +

    Vocalinux 0.14.0-beta as Flatpak: whisper.cpp with Vulkan, XDG config/models/logs, XWayland text injection, and system tray integration.

    +     +     + + +

    First Flatpak release: whisper.cpp engine with Vulkan GPU support, XDG-compliant data paths, and XWayland text injection.

    +     +     + + +

    Guided whisper.cpp model variants, hotplug keyboard rescanning, and IBus setup refinements.

    +     +     + + +

    Non-ASCII text injection, IBus Wayland detection fixes, Pop!_OS dependency support, and code quality improvements.

+# Distribution Testing Checklist
+
+Use this checklist when testing Vocalinux on a new Linux distribution.
+
+## Pre-Installation
+
+### System Information
+- [ ] Record distribution name and version
+  ```bash
+  cat /etc/os-release
+  ```
+
+- [ ] Record desktop environment
+  ```bash
+  echo $XDG_CURRENT_DESKTOP
+  ```
+
+- [ ] Record display server
+  ```bash
+  echo $XDG_SESSION_TYPE
+  echo $WAYLAND_DISPLAY  # For Wayland
+  echo $DISPLAY          # For X11
+  ```
+
+- [ ] Record architecture
+  ```bash
+  uname -m
+  ```
+
+- [ ] Run the dependency checker
+  ```bash
+  bash scripts/check-system-deps.sh
+  ```
+
+- [ ] Note missing packages
+- [ ] Note any special requirements (musl libc, specific library versions, etc.)
+
+## Installation
+
+### Standard Installation
+- [ ] Download installer
+  ```bash
+  curl -fsSL https://raw.githubusercontent.com/VocaHQ/vocalinux/main/install.sh -o /tmp/vl.sh
+  ```
+
+- [ ] Run installer
+  ```bash
+  bash /tmp/vl.sh
+  ```
+
+- [ ] Check for errors during installation
+- [ ] Verify virtual environment was created
+  ```bash
+  ls -la ~/.local/share/vocalinux/venv/
+  ```
+
+- [ ] Check wrapper scripts exist
+  ```bash
+  ls -la ~/.local/bin/vocalinux*
+  ```
+
+- [ ] Check desktop entry was created
+  ```bash
+  ls -la ~/.local/share/applications/vocalinux.desktop
+  ```
+
+- [ ] Check icons were installed
+  ```bash
+  ls -la ~/.local/share/icons/hicolor/scalable/apps/vocalinux*
+  ```
+
+## Post-Installation
+
+### Launch from Terminal
+- [ ] Launch from terminal
+  ```bash
+  ~/.local/bin/vocalinux-gui
+  ```
+
+- [ ] Check for startup errors
+- [ ] Verify the application starts
+- [ ] Check that tray icon appears
+- [ ] Verify keyboard shortcut works (Hold Right Alt by default)
+
+### Launch from Application Menu
+- [ ] Launch from desktop environment's application menu
+- [ ] Verify the application starts
+- [ ] Check that tray icon appears
+
+### Core Functionality Tests
+
+#### Tray Icon and Menu
+- [ ] Left-click tray icon opens menu
+- [ ] Right-click tray icon opens settings menu
+- [ ] "Start Recording" menu item works
+- [ ] "Stop Recording" menu item works
+- [ ] "Settings" menu item opens settings dialog
+- [ ] "Quit" menu item exits the application
+
+#### Keyboard Shortcuts
+- [ ] Default shortcut (Hold Right Alt) starts push-to-talk recording
+- [ ] Custom shortcuts can be configured in Settings
+- [ ] Shortcut works in different applications (terminal, text editor, browser)
+
+#### Audio Recording
+- [ ] Recording starts without errors
+- [ ] Default audio device is detected
+  ```bash
+  # Check audio devices
+  pactl list sources short  # PulseAudio
+  # or
+  arecord -l                 # ALSA
+  ```
+
+- [ ] Audio levels are adequate
+- [ ] Start sound plays (ascending tone)
+- [ ] Stop sound plays (descending tone)
+
+#### Speech Recognition
+- [ ] Speech is transcribed accurately
+- [ ] Transcription appears in target application
+- [ ] Punctuation works
+- [ ] Capitalization works
+- [ ] No backslash escapes in output (no \\', \\", etc.)
+
+#### Text Injection
+
+##### X11 (if applicable)
+- [ ] Text injection works with xdotool
+- [ ] Works in different applications:
+  - [ ] Terminal (gnome-terminal, konsole, etc.)
+  - [ ] Text editor (gedit, kate, mousepad, etc.)
+  - [ ] Browser (Firefox, Chromium, etc.)
+  - [ ] LibreOffice Writer
+  - [ ] Chat applications (Discord, Telegram, etc.)
+
+##### Wayland (if applicable)
+- [ ] Text injection works with wtype
+- [ ] Works in Wayland-native applications
+- [ ] XWayland fallback works if needed
+- [ ] Works in same applications as X11 test list
+
+##### Universal (ydotool if available)
+- [ ] Text injection works with ydotool
+- [ ] Works across both X11 and Wayland
+
+### Settings Dialog
+- [ ] Settings dialog opens from tray menu
+- [ ] Can configure audio input device
+- [ ] Can configure keyboard shortcuts
+- [ ] Can enable/disable sounds
+- [ ] Can configure recognition engine (VOSK/Whisper)
+- [ ] Can configure language
+- [ ] Settings persist after restart
+- [ ] Config file is created correctly
+  ```bash
+  cat ~/.config/vocalinux/config.json
+  ```
+
+### Model Download (if using Whisper)
+- [ ] Model download works
+- [ ] Download progress is shown
+- [ ] Model is saved to correct location
+  ```bash
+  ls -la ~/.local/share/vocalinux/models/
+  ```
+
+### Error Handling
+- [ ] Graceful handling when no microphone is available
+- [ ] Graceful handling when text injection fails
+- [ ] Error messages are helpful
+- [ ] Application doesn't crash on errors
+
+## Performance
+
+- [ ] Application starts within reasonable time (< 5 seconds)
+- [ ] Recording starts/stops responsively
+- [ ] Transcription appears without significant lag
+- [ ] Memory usage is reasonable
+  ```bash
+  # Check memory usage
+  ps aux | grep vocalinux
+  ```
+
+- [ ] CPU usage is reasonable during idle
+- [ ] CPU usage is reasonable during recording
+
+## Cleanup and Uninstallation
+
+- [ ] Application can be quit cleanly
+- [ ] No processes left running
+  ```bash
+  ps aux | grep vocalinux
+  ```
+
+- [ ] Uninstallation works
+  ```bash
+  bash ~/.local/share/vocalinux/uninstall.sh  # if exists
+  # or manual cleanup
+  rm -rf ~/.local/share/vocalinux
+  rm -rf ~/.config/vocalinux
+  rm ~/.local/share/applications/vocalinux.desktop
+  rm ~/.local/bin/vocalinux*
+  ```

+## Submitting Results
+
+After completing the checklist:
+
+1. **Create a GitHub issue** with the title:
+   `Distro Test Results: [Distribution Name] [Version]`
+
+2. **Include the checklist** (either filled out or as a summary)
+
+3. **Attach logs** if there were errors:
+   - Installer output
+   - Application output from terminal
+   - Journal logs: `journalctl --user -u vocalinux -b`
+
+4. **Mention any workarounds** you found
+
+5. **Suggest improvements** to the documentation or installer
+
+## Testing Tips
+
+1. **Test early, test often** - Don't wait until everything is installed to test
+2. **Keep notes** - Document everything, even things that seem minor
+3. **Be thorough** - Test with multiple applications if possible
+4. **Be patient** - Some distributions may require workarounds
+5. **Share your findings** - Even negative results are valuable

+"""Tie the Flatpak's dependency set back to the lock that everything else uses.
+
+`packaging/flatpak/python3-dependencies.yaml` was generated once from a package
+list typed on a command line, then hand-edited, then never compared to anything.
+By 2026-09-10 ten of its fifteen shared packages were behind
+`requirements/runtime.txt` and two more (pydub, lxml) were still built after
+#705 deleted them for having no imports in `src/`.
+
+The one that mattered was pywhispercpp 1.4.1, under the project's own
+`>=1.5.0`. Nothing could catch it: the Flatpak installs the project with
+`pip3 install --no-deps`, so the constraint in `pyproject.toml` is never
+evaluated, and `recognition_manager.py` degrades GPU `context_params` below
+1.5.0, so Flatpak users lost that quietly rather than loudly.
+
+`packaging/appimage/build.sh` has done this check for the AppImage since #743.
+These are the Flatpak's, and they run offline: `scripts/sync_flatpak_deps.py`
+needs PyPI to look a URL up, but everything asserted here is already in the
+repo.

+"""Regression tests for issue #478.
+
+On Wayland, IBus only delivers commit_text() to applications through a *real*
+IM engine. A bare ``xkb:*`` engine (or none) is a layout passthrough, so
+selecting the IBus backend there is a silent no-op. is_ibus_active_input_method()
+must require a real engine on Wayland regardless of how IBus was detected, while
+leaving X11/XWayland (XIM) behavior unchanged.
+
+Note: we patch via ``patch.object`` on a held module reference (and call the
+function through that same reference) rather than by dotted string, so the
+patched ``get_current_engine`` / ``is_ibus_daemon_running`` and the function
+under test always share one module object even when other test files re-import
+``ibus_engine`` during a full-suite run.

+``restore_xkb_layout`` must not call ``setxkbmap`` on Wayland. That tool only
+reaches the XWayland X11 server, so re-applying a captured (or default us)
+layout leaves XWayland apps on the wrong map while native Wayland apps and
+``localectl`` stay correct.
+
+After scoped IBus restore, ``sync_xwayland_layout_from_gnome`` may call
+``setxkbmap`` to restore GNOME's complete XKB configuration on XWayland —
+every xkb input source plus all xkb-options. Writing only the current
+source's layout strands XWayland on a single-group keymap, which kills both
+XKB group toggles (Alt+Shift) and Mutter's group-index switching
+(Super+Space) for X11 clients until relogin (#848). That path must not go
+through ``restore_xkb_layout``.

+closed the pipe mid-download (curl error 23) and made bash read the rest of

+"""Behavioral tests for the installer's existing-install upgrade path.
+
+Re-running install.sh used to replay first-time setup with no way to keep the
+existing configuration (issue #1009): the mode menu offered only interactive or
+automatic, automatic mode forced whisper.cpp regardless of the configured
+engine, and nothing said config.json would be kept. The upgrade path detects a
+venv + config.json pair, offers "Upgrade (keep current settings)" as the
+default, installs dependencies for the configured engine, and never rewrites
+the file.

+"""A nightly artifact's filename and its own metadata have to agree.

+`nightly.yml` used to build the wheel and then rename the file to carry the

+claimed 0.16.1.dev+. pip installed that without complaint for as long

+Integration-style tests for the Silero VAD path in _record_audio.
+
+Drives the recording loop with a mocked PyAudio stream and a Mock SileroVAD
+returning scripted speech probabilities. Verifies:
+
+- silence-only input -> no transcription segment is enqueued
+- speech followed by silence -> _enqueue_audio_segment is called after silence_timeout
+- speech -> silence_counter resets, no premature flush
+- vad_sensitivity threshold mapping kicks in (sens=1 vs sens=5 give different decisions)
+- Silero state is reset at the start of every recording session

+"""Guard what a published release promises about itself.
+
+v0.16.1 shipped four assets — two AppImages of ~100 MB, a wheel and an sdist —
+with no checksum, no signature and no provenance, in a project that pins the
+digest of all 67 models it downloads. It also built the same version three times
+on three runners (`build-and-release`, `build-appimage-arm64`, `publish-pypi`),
+so the wheel on PyPI was never the wheel on the GitHub release, and a checksum
+for one would not have described the other.
+
+These tests pin the shape of the fix: verify independent builds, publish only
+the canonical distributions, and cover every artifact with one manifest.
+Parsed as text rather than YAML on purpose — the
+sibling workflow guards do the same, and the only YAML parser on hand reaches
+the venv transitively through pre-commit.

+Tests for the SettingsDialog.
+
+Since SettingsDialog inherits from Gtk.Dialog which is mocked during tests,
+we can't easily test the actual class methods. Instead, we test the core
+logic that the settings dialog is supposed to execute.
+
+UX Design Notes tested:
+- Instant-apply pattern: settings apply immediately when changed
+- No action buttons - uses title bar close (GNOME HIG)

+"""Tests for OpenAI Whisper checkpoint file naming.

+Regression cover for the review finding on #713: the file name was derived as

+only ships the versioned checkpoint, so `openai-whisper` stores `large-v3.pt`.
+The consequences were a 2.9GB model downloaded and stored twice, and a settings
+dialog that reported "large" as missing no matter how often it was fetched.

+Regression tests for #984: standalone windows must not carry the DIALOG
+type hint.
+
+On GTK's Wayland backend, a toplevel with the DIALOG hint and no transient
+parent becomes an "orphan dialog": the next toplevel in the app to receive
+keyboard focus silently becomes its xdg_toplevel parent. GNOME then treats
+the pair as one window for minimize/restore, raising, and workspace moves.
+
+The dictation pad is a plain Gtk.Window (NORMAL hint) that is focused
+constantly, so any standalone Gtk.Dialog left parentless gets bound to it.
+Settings, the transcript viewer, and the log viewer are standalone windows
+and must opt out with the NORMAL hint.

+# AGENTS.md — vocalinux.com (`web/`)
+
+Guidelines for agents working on the marketing site only. For the Python desktop app, git worktrees, and PR rules, see the repo root [`AGENTS.md`](../AGENTS.md). Do not create branches, commits, or pull requests in the primary checkout.
+
+## What this package is
+
+Next.js (App Router) static marketing + SEO guides for Vocalinux. Source lives here; production deploys from `web/` (static export to `out/`).
+
+## Product and design authority
+
+Read these before changing marketing UI or copy:
+
+| File | Holds |
+|---|---|
+| [`PRODUCT.md`](./PRODUCT.md) | Who the site is for, product truth, claims we can make |
+| [`DESIGN.md`](./DESIGN.md) | Visual system: color, type, layout, components, don'ts |
+
+Do not invent features, benchmarks, user counts, or privacy claims that contradict `PRODUCT.md`. Prefer screenshots and install commands over abstract feature theater.
+
+## Commands
+
+```bash
+cd web
+npm install
+npm run dev          # local (prefer -H 0.0.0.0 -p 3456 when sharing)
+npm run build        # static export
+npm run lint
+npm test
+npm run typecheck
+```
+
+Viewport layout checks (needs a running server for the browser leg):
+
+```bash
+# with http://127.0.0.1:3456 up
+BASE_URL=http://127.0.0.1:3456 npm test -- --testPathPatterns=viewport-layout
+# or
+npm run test:viewport
+```
+
+## Layout map
+
+- Home: `src/app/page.tsx`
+- Shared SEO shell: `src/components/seo-subpage-shell.tsx`
+- Tokens / utilities: `src/styles/globals.css`, `tailwind.config.ts`
+- Fonts: system display + body stacks in `src/styles/globals.css` (no remote webfonts)
+
+## Maintaining this file
+
+Update when website build, structure, or design authority paths change. Keep product claims and visual tokens in `PRODUCT.md` / `DESIGN.md`, not duplicated here.

+# Design system: vocalinux.com
+
+## Overview
+
+**Creative north star: the Linux desk in the Voca family**
+
+Vocalinux.com is a Voca product site. It should feel related to VocaHQ, VocaMac, VocaPhone, and VocaGateway before anyone reads the logo: warm paper, deep green ink, one teal accent, editorial type, flat surfaces, and real product proof.
+
+The Linux-specific job is to show local desktop dictation with distribution and display-server truth. Pair a GTK-style window (not macOS traffic lights) with a terminal. Explain the user outcome before the install command.
+
+Child pages share the same shell, tokens, and paper canvas. Paper is the only
+marketing theme. There is no site-wide dark mode. The screenshots gallery is
+the exception: a page-local Light/Dark flip shows the captured GTK shots in
+both appearances, defaulting to `prefers-color-scheme` until the visitor
+overrides it for that tab.
+
+## Colors
+
+Warm paper with one product teal. No second chromatic brand color.
+
+### Surfaces
+- **Paper** `#f4f1e8`: page canvas
+- **Deep paper** `#ebe5d8`: recessed bands (install, engines)
+- **Bright paper** `#fffdf7`: windows and cards
+- **Dark ink** `#0b1a15`: panel bar, terminal, optional dark band
+
+### Ink
+- **Ink** `#14231c`: headings and strong borders
+- **Muted copy** `#58625c`: body
+- **Faint** `#5f6861`: metadata
+- **Line** `#c9c8bd`: quiet borders
+- **Line dark** `#9ea59f`: window outlines
+
+### Accent
+- **Brand teal** `#0f6b57`: primary buttons, links, live marks
+- **Dark teal** `#0b493d`: hover / pressed
+- **Mint** `#cfe9dc` / **mint soft** `#e5f2eb`: tags and chips
+
+### Annotations only
+- **Sun** `#e9b949`: focus rings
+- **Red** `#de6a57`: recording dot, never as a brand fill
+
+### Named rules
+**The family paper rule.** Backgrounds stay warm paper, with dark ink only for the tray bar, terminal, and ribbon. Not zinc white, not a second site-wide dark theme, not purple mesh.
+
+**The one signal rule.** Teal is the only chromatic accent on marketing pages. Yellow and red are physical details (focus, recording), not competing brands.
+
+**The no-gradient rule.** Solid fills only. No linear, radial, or conic gradients.
+
+## Typography
+
+System-first, same stacks as VocaHQ / VocaMac.
+
+- **Display:** Avenir Next / Helvetica Neue / Segoe UI / Arial
+- **Body:** system UI sans
+- **Mono:** system UI monospace for commands, tags, and metadata
+
+No remote webfonts. No Geist, Inter, or Bricolage as the page face.
+
+### Hierarchy
+- **Hero display:** clamp ~3.7–7.4rem, weight ~780, tracking -0.075em, line-height ~0.92
+- **Section title:** clamp ~2.2–4.7rem, tracking -0.065em
+- **Body:** 16–18px, line-height ~1.65. Reflow with the shell; do not pretty-wrap or cap titles at 20ch
+- **Mono tags:** ~0.7rem, used sparingly
+
+Accent words in a headline use the same family, `font-style: normal`, brand color. Do not mix a second family into a heading.
+
+## Layout
+
+- Shell: `min(1180px, calc(100% - 2rem))`
+- Sticky paper header, ~70px, one line of nav on desktop
+- Home first viewport: split offer + Linux workbench when wide; stacked on small screens
+- Section padding ~5.5–9rem desktop, ~4–6rem mobile
+- Alternate paper / deep paper for rhythm
+- Child pages: breadcrumbs + content in the same shell
+
+## Elevation and shapes
+
+Flat fills, 1px borders, paper-window shadows. Small rotations only on decorative notes, never on long copy or controls.
+
+- Controls: 0.45rem radius
+- Windows: ~10–14px radius
+- Pills only for tiny tags (engine badge, section tag)
+
+## Components
+
+### Buttons
+- Primary: brand teal, paper-bright text, 44px min height
+- Homepage / closing CTA: "Install Vocalinux", jumps to `#install`
+- Secondary: transparent with a 3:1 control outline
+- Hover: 2px lift, no bounce scale as the only affordance
+- Focus: 3px sun outline, 3px offset
+
+### Linux window
+- GTK-style headerbar: title, then window controls on the **right**
+- Grey control circles, not red/yellow/green traffic lights
+- Bright paper body, dark ink panel bar above (tray analogue)
+
+### Terminal
+- Dark ink surface, mint command text, copy in the chrome
+- GTK headerbar: copy on the left, title centered, grey window controls on the **right**
+- Prompt is `user@linux:~$` with colored user, host, and path, not a Mac `$`
+- Long URLs wrap (`break-all` / `overflow-wrap`) so mobile never overflows
+
+### Navigation
+- Sticky paper bar, mark + name, 3–5 text links, GitHub stars on desktop
+- Mobile menu keeps Install Vocalinux as the conversion action
+- Real mobile disclosure with `aria-expanded`
+- Resource-rich footer, not a second mega-menu in the header
+
+### Screenshot gallery
+- Paper chrome stays paper; do not put `html.dark` on this page
+- Light/Dark is a sliding switch over stacked light and dark PNG pairs
+- Default from the browser color scheme; `sessionStorage` holds a tab override
+
+## Do's and don'ts
+
+### Do
+- Lead with the dictation outcome, then the install command
+- Use real screenshots and a faithful Linux window, not a fake SaaS dashboard
+- Keep product claims accurate (offline local engines; remote only when configured)
+- Honor `prefers-reduced-motion`
+
+### Don't
+- CSS gradients, gradient text, mesh/orbs, or glass panels
+- macOS traffic-light chrome on Linux surfaces
+- Tracked uppercase eyebrows on every section
+- Invent metrics, testimonials, or "AI-powered" claims
+- Recolor the Vocalinux mark

+# Product (vocalinux.com)
+
+## Platform
+
+web (Next.js marketing site under `web/`)
+
+## Users
+
+Linux desktop users who want voice dictation that stays on their machine: developers, writers, and people reducing keyboard strain. They already live in terminals, browsers, IDEs, and GTK/Qt apps.
+
+## Product purpose
+
+Vocalinux is free, open-source offline voice dictation for Linux. It turns speech into typed text in whatever app has focus, using local engines (whisper.cpp default, Faster Whisper, Whisper, VOSK, Parakeet) or an optional user-configured remote API. Success is: install once, dictate in any app, without cloud transcription or telemetry.
+
+## Positioning
+
+Offline-first Linux voice typing with real desktop integration (system tray, X11 and Wayland text injection, toggle and push-to-talk, Silero VAD, suspend recovery). A cloud SaaS voice product cannot truthfully claim local-only models plus no usage telemetry from the installed app.
+
+## Operating context
+
+- Install via a one-line shell installer, AppImage from GitHub Releases, AUR, Snap (`--edge`), or Flatpak release bundle; then run from PATH, app menu, or the AppImage binary
+- System tray indicator and settings GUI (GTK) with searchable sidebar navigation and an always-visible sidebar footer for dictation status / Test Dictation / Close
+- Dictation into terminals, browsers, IDEs, office apps
+- Engines and models chosen for hardware (CPU, optional Vulkan GPU with discrete-device preference)
+- Guides and comparison pages on vocalinux.com; source on GitHub
+
+## Capabilities and constraints
+
+- Engines: whisper.cpp (default), Faster Whisper, OpenAI Whisper, VOSK, Parakeet, optional Remote API
+- Speech languages: large selectable catalog (~33 + Auto-detect) shared by Settings/CLI; VOSK only lists languages with official Alphacephei models; remaining Whisper languages available via Auto-detect
+- Display servers: X11 and Wayland
+- Shortcut modes: push-to-talk default (hold Right Alt / Option); toggle available; left/right modifier distinction; configurable modifier+key combos
+- Searchable language combobox; delete unused downloaded speech models from Settings
+- Optional voice commands with localized punctuation phrases for common languages; Silero neural VAD with amplitude fallback
+- Dictation Pad: in-app window that receives dictation for manual copy-out; the Wayland-safe path that skips text injection entirely
+- Per-language dictation shortcuts, optional follow of the active keyboard layout, and a tray history menu with recent dictations
+- Floating dictation overlay, optional lowering of other audio while dictating, and custom dictionary terms bias plus transcript corrections
+- Audio capture via PipeWire (microphone and system-audio sources) or PortAudio; Wayland text injection via IBus, wtype, ydotool, or the RemoteDesktop portal
+- Opt-in D-Bus activation so compositor global shortcuts and scripts can start dictation
+- File transcription with per-speaker labels (`--transcribe-file` / tray), powered by TinyDiarize
+- Continuous dictation polish: capitalize after sentence punctuation; trailing space after each completed utterance
+- Optional auto-pause while configured apps run; optional idle model keep-alive unload
+- Optional JSONL persistence of transcription history to disk (off by default)
+- Settings Proxy page: outbound SOCKS5 or HTTP CONNECT proxy (optional auth) for model downloads and update checks
+- Speech Model Advanced pickers stage engine/size/variant/language changes until Download is confirmed
+- In-app update checker (stable/nightly) with tray notification when a newer GitHub release is available
+- Settings About page groups this app, VocaHQ family sites, and talk-to-us links (GitHub, Discord, X, email)
+- Optional disable of the missing-tray warning dialog
+- Settings → Audio family tone picker (Lift, Flick, Ember, Step, Voca, Soft, Chirp, Scale, Drop, Glass, Off) with Preview; new installs default to Voca; catalog files are the family preview WAVs
+- Vulkan discrete GPU auto-select with manual device override in Advanced settings
+- Native GTK installs follow the OS dark/light preference unless `GTK_THEME` is already set
+- Wayland: IBus when `ibus-wayland` is running, including on compositors previously treated as unbridged
+- Packaging: install.sh (distro python3-gi required; no pip sdist of PyGObject), .deb/.rpm (x86_64/aarch64), AppImage (x86_64/aarch64), AUR, Flatpak (local/Flathub status as documented); uv.lock pins Python deps; Justfile replaces Makefile
+- No usage telemetry in the installed app
+- AGPL-3.0; marketing version string is tracked in site package/version surfaces
+- Website is Next.js marketing + SEO guides (static export); languages page documents per-engine support honestly
+
+## Brand commitments
+
+- Name: Vocalinux (part of [VocaHQ](https://vocahq.com) with VocaMac / VocaWin)
+- Mark: shared Voca family mic for the app icon, tray states, and site favicons (`public/`)
+- Warm paper surfaces and Voca teal, matching the family web standard
+- Voice: practical, specific, Linux-native; not hype-first SaaS copy
+
+## Evidence on hand
+
+- Real app screenshots in `public/screenshots/`
+- Install/uninstall commands pointing at GitHub raw install scripts
+- JSON-LD on the home page (software application, FAQ, how-to)
+- Do not invent user counts, testimonials, or benchmarks
+
+## Product principles
+
+1. Privacy is default: local engines process audio on-device; remote only when the user opts in.
+2. Ship the install path and real desktop proof, not abstract feature theater.
+3. Stay honest about engines, hardware, and what runs offline vs remote.
+4. Prefer Linux craft and clarity over generic AI-startup marketing patterns.
+
+## Accessibility
+
+- Respect `prefers-reduced-motion`
+- Body text contrast at least 4.5:1; large text at least 3:1
+- Keyboard-reachable install copy controls and navigation

+# Vocalinux website
+
+Marketing site for [vocalinux.com](https://vocalinux.com), built with Next.js and deployed as a static export (GitHub Pages).
+
+Product claims and design constraints: [PRODUCT.md](PRODUCT.md), [DESIGN.md](DESIGN.md). Agent notes: [AGENTS.md](AGENTS.md).
+
+## Development
+
+```bash
+npm install
+npm run dev
+```
+
+## Production build
+
+```bash
+npm install
+npm run build
+```
+
+Static output is written to `out/`.
+
+### Local preview of the build
+
+```bash
+cd out
+python3 -m http.server 3000
+```
+
+Open `http://localhost:3000`.
+
+## Scripts
+
+| Script | Purpose |
+|--------|---------|
+| `npm run dev` | Dev server |
+| `npm run build` | Production static export |
+| `npm run deploy` | Build and prepare GitHub Pages (`.nojekyll`, `CNAME`) |
+| `npm run lint` | ESLint |
+| `npm run typecheck` | TypeScript |
+
+## Deployment
+
+Push to `main` triggers the site workflow. Production host: **vocalinux.com**.
+
+Manual path:
+
+```bash
+cd web
+npm install
+npm run deploy
+```
+
+That produces `out/` with `.nojekyll` and a `CNAME` for vocalinux.com.
+
+## Layout
+
+```
+web/
+├── src/
+│   ├── app/            # Next.js app routes
+│   ├── components/
+│   │   ├── site-chrome.tsx
+│   │   └── ui/         # Reusable UI components
+│   ├── hooks/
+│   └── lib/
+├── public/             # Static assets and screenshots
+├── out/                # Build output (generated)
+└── package.json
+```
+
+## Configuration notes
+
+- Custom domain: `deploy` script writes `out/CNAME`
+- Subdirectory deploy: set `basePath` in `next.config.js` if needed
+- Family workbench UI: warm paper, system type, same language as VocaHQ ([DESIGN.md](DESIGN.md))
+
+## Troubleshooting
+
+| Symptom | Check |
+|---------|--------|
+| Module not found | `npm install` |
+| Type errors | `npm run typecheck` |
+| Lint errors | `npm run lint` |
+| 404 on GitHub Pages | Ensure `out/.nojekyll` exists |
+| Assets 404 | Confirm `basePath` matches deploy path |
+
+## License
+
+Same as the main Vocalinux project ([AGPL-3.0](../LICENSE)).

+# Tux
+
+Linux mascot used on the Open Graph card.
+
+`tux.svg` is a flat derivative of Larry Ewing's Tux: the original

+No gradients, blurs, or glares. `tux-classic.svg` is the unaltered
+Wikimedia vector.
+
+Original drawing by Larry Ewing with The GIMP.
+Vector by Larry Ewing, Simon Budig, and Garrett LeSage.
