Add render-lock-spec subcommand for exporting lock specification to pixi.toml

[maresb]

Description

Leverage conda-lock's source parser to generate pixi.toml

The command

conda-lock render-lock-spec --kind=pixi.toml --stdout ...

is a stand-in replacement for

conda-lock lock ...

It takes the same CLI arguments and outputs a pixi.toml file.

For example, based on the command

conda-lock --file=environments/dev-environment.yaml --file=pyproject.toml

this translates to

conda-lock render-lock-spec --kind=pixi.toml --stdout --file=environments/dev-environment.yaml --file=pyproject.toml --pixi-project-name=conda-lock --editable conda-lock=. > pixi.toml

which produces the included pixi.toml with the warnings:

~/repos/conda-lock/conda_lock/src_parser/markers.py:73: UserWarning: Marker 'python_version < "3.11"' contains environment markers: {'python_version'}. Only {'os_name', 'sys_platform', 'platform_system'} are supported.
  warnings.warn(

  warnings.warn(

  warnings.warn(f"Extras not supported in Conda dep {dep}")

TODO:

• commit the pixi.toml
• add the option for an editable dependency
• write dict values as toml instead of json (uses = instead of : as a key-value separator)

Ugh, tomlkit is butchering tables and I don't understand why. Things were simpler when generated as pure text. 😞
