# 2.0.0
|
||
|
|
## Features:
|
||
|
|
- **Python Wheels**: Wheels are supported for linux including manylinux1, manylinux2010, manylinux2014
|
||
|
|
- **Nixpkgs python packages**: Nixpkgs is now treated as a separate provider. That means packages can be taken directly from there, independent on their availability from pypi.
|
||
|
|
- **Configurable Providers**: The user can now freely decide where packages should be taken from either via a default or on a per package basis. Currently available provider are `nixpkgs`, `sdist`, `wheel`.
|
||
|
|
- **Core architecture - Python Overrides**: The core of mach nix now produces python overrides instead of nixpkgs overlays which makes it much more composible and allows for a less strange API.
|
||
|
|
- **Overlay support**: `mkPython` and lower level interfaces now accept new parameter `pkgs` and `python` which indirectly enables you to use any nixpkgs overlays (But don't use this for modifying python packages. Better do this with **Python Overrides**)
|
||
|
|
- **Python Overrides support**: `mkPython` now accepts new parameter `overrides_pre` and `overrides_post` each allowing to inject a list of python overrides to apply before and after the mach-nix internal overrides. This allows you to fixup packages or add your own modifications to them.
|
||
|
|
- **Extras support**: All providers now fully support python [extras](https://www.python.org/dev/peps/pep-0508/#extras). That means requirements like for example '`requests[security]`' will be correctly resolved.
|
||
|
|
|
||
|
|
## Nix Interface changes:
|
||
|
|
- Removed:
|
||
|
|
- **mkPythonExpr**: removed in favor of `machNixFile` and `machNix`
|
||
|
|
- Added:
|
||
|
|
- **machNixFile** which generates a nex expresison
|
||
|
|
- **machNix** which evaluates the generated nix expression to get `overrides` and `select_pkgs`
|
||
|
|
- Changed:
|
||
|
|
- **mkPython**:
|
||
|
|
- Removed arguments:
|
||
|
|
- `python_attr` in favor if `python`
|
||
|
|
- `prefer_nixpkgs` in favor of `providers`
|
||
|
|
- `nixpkgs_commit` in favor of `pkgs`
|
||
|
|
- `nixpkgs_tarball_sha256` in favor of `pkgs`
|
||
|
|
- Added arguments:
|
||
|
|
- `overrides_pre`: list of python overrides to apply before the machnix overrides
|
||
|
|
- `overrides_post`: list of python overrides to apply after the machnix overrides
|
||
|
|
- `pkgs`: pass custom nixpkgs. Only used for manylinux wheel dependencies.
|
