inputs:
  files:
    description: >-
      Specify the location of the dependencies files to parse. (defaults to 'pyproject.toml')
      Separate a list of multiple source files by spaces (e.g. 'pyproject.toml[test] requirements.txt').
    required: true
    default: pyproject.toml
  output:
    description: >-
      Specify the location and name of the conda environment file to generate. (defaults to 'environment.yml')
    required: true
    default: environment.yml
  channels:
    description: >-
      List the conda channels to include in the environment file. (defaults to 'conda-forge')
      Separate a list of multiple channels by spaces (e.g. 'conda-forge defaults').
    required: true
    default: conda-forge
  extras:
    description: >-
      Specify one or more optional [extras_require] sections to add to all source files (s.a.).
      (e.g. 'test' to include package that you would normally install with 'pip install pkg[test]').
      Note that for individual sources in 'files', the '[extra]' syntax is also possible.
    required: false
  build_system:
    description: >-
      if set to 'include' the dependencies listed under [build-system] (for 'pyproject.toml') or [options]:setup_requires (for 'setup.cfg') will be added to the environment
      (default is 'omit' so no build system dependencies will be installed)
    required: false
    default: omit
  pip:
    description: >-
      List of packages to install via pip instead of conda.
      The dependencies will be listet under the pip section in the environment file.
      If a dependency is listed with its URN, it will always be installed via pip (e.g. 'pydeps2env @ git+https://github.com/CagtayFabry/pydeps2env')
    required: false
