requirements-language-server

Language server for requirements.txt.

Currently python's requirement.txt has 2 types:

• PEP508: supported by:
  • setuptools
• pip: supported by:
  • pip
  • pip-compile

The difference is that PEP508 doesn't support pip's options.

For pyproject.toml:

[tool.setuptools.dynamic.dependencies]
file = "requirements.txt"

[tool.setuptools.dynamic.optional-dependencies.dev]
file = "requirements/dev.txt"

We recognize requirements.txt and requirements/dev.txt as PEP508's requirements.txts and display errors for all pip's options. For other requirements.txts, we recognize them as pip's requirements.txts.
