# Voculinux justfile
# Convenient commands for development
# Run `just` to list all recipes. Python tooling runs through `uv run` against
# .venv/ — run `just deps` after cloning (requires uv).
#
# Two environments, deliberately separate:
#   .venv/  dev tooling, built by uv from .python-version (3.13). `just deps`
#           builds PyGObject from the lock and needs libgirepository-2.0-dev
#           (Ubuntu 24.04+) or glib2-devel (Fedora 40+), plus cairo-gobject
#           headers on Fedora. Debian 12 cannot build 3.56; use `just install-dev`.
#   venv/   what `just install` creates, always from the system Python so the
#           distro PyGObject package is importable.
#           install.sh ignores an activated .venv and rebuilds
#           venv/ if another interpreter created it, so `just install` is safe to
#           run from any shell. Override with SYSTEM_PYTHON=/usr/bin/python3.12.

# Extras and groups installed by `just deps`. `uv sync` prunes whatever the flags
# do not name — omitting `--group lint` really does uninstall the linters.
# Recipes that run tools use `uv run --no-sync` so they do not undo `just deps-all`
# (whisper/vosk/docs). They depend on `_tooling` for the same reason: with nothing
# left to create .venv/, `uv run --no-sync` on a fresh clone leaves an empty one
# behind and fails with `Failed to spawn: pytest`. CI lints with `--only-group lint`
# instead: that skips the project, whose pyaudio/PyGObject need system headers a
# lint runner has no reason to install.

# Fail before `uv sync` when the headers pyaudio, pycairo and PyGObject need are
# absent. Without this, the first error is a C compiler traceback from inside a
# dependency build, which reads as a uv problem rather than a distro package.
# PyGObject/pycairo checks apply only on Linux, matching the dependency marker.
# An existing .venv/ with the platform's native packages skips the header check.

# Create .venv/ and keep it matching the lock. --inexact is what makes this safe

# string out of version.py and needs a bare interpreter, not a sync.
