Taking many tips from our `default.nix` (thanks @nt!) this seems to be
the minimal overlay required for a flake to get up and running with
`piker chart` B)
Notes,
- for now, we're pinning to a major `cpython` version (3.13)
- ensure we (can) build with `nixpkgs.qt6.qtwayland`
- add the minimal Qt ld-lib-path linkings including those for plugin
use (required for wayland mode).
- for now, hardcode "wayland" platform-mode and the linux standard
"xdg-shell" integration.
- leave some TODOs to better parameterize around py versions.
Particularly using their recommended "impure template",
- https://pyproject-nix.github.io/pyproject.nix/templates.html#impure
- code: https://github.com/pyproject-nix/pyproject.nix/blob/master/templates/impure/flake.nix
Note the `shellHook` now contains various `uv`-specific osenv settings
and cmds to get a dev-env setup the way i would do it by default, that
includes all dev and extra (group) deps. For now i've hard coded the
"virt-env subdir" used by `uv` to match the cpython version. We can
obviously parameterize this much better in the future.
For those who want to spawn a diff shell then bash see the commented
line, for ex. i personally use `nix develop -c uv run xonsh`.
Makes it easier to pass the overrides to multiple p2n functions (like
hopefully `.mkPoetryEnv`). Also, add some commented attempts at using
`mkPoetryEnv` and todo list for "why", remove the `poetry` CLI main
point from the pyproject.toml, bump the poetry lock file.
NB: for now this is linking to a presumed local clone of the
`poetry2nix` repo since part of fixing what was adjusted here needs to
be patched upstream, which means hackin on the p2n repo in tandem B)
Since there's some dependency build issues we need
to tweak the following to get baseline `nix develop` working:
- drop `python-levenshtein` (required by `fuzzywuzzy[speedup]`) for now
since the overlay and/or wheel install needs to be properly figured
out.
- build `pyqt5` from src for the moment (since `preferWheel` doesn't
seem to be workin?) despite it taking forever XD
- add in the `flake.lock` file.
As per the hot tip from the edgecases.md,
https://github.com/nix-community/poetry2nix/blob/master/docs/edgecases.md#modulenotfounderror-no-module-named-packagename
Factor all the (mostly `setuptools`) overrides into
a `pypkgs-build-requirements` set and `.extend()` in any `preferWheel`
additions (`polars`, `pyqt`, etc.) before passing to to
`mkPoetryApplication(overrides=<it>)`.
Add a buncha todos for improving the poetry2nix pkging including:
- adding the override requirements to the json file for all our deps
in the `pypkgs-build-requirement` set.
- maybe propose docs for the edgecases.md to show how to do the auto-gen
set (via func) AND extend with further overrides like `preferWheel`?
- task to support `polars` build from src (by copying `cryptography`
stuff) instead of only from a wheel?
- get pyqt5 building from wheel since it seems to be taking forever from
src..
- get pyqt6 working in general - going to require taking stuff from
nixpkgs and applying it in the overrides of p2n.
