This package provides a Hatch plugin for configuring "variants" of dependencies according to an environment variable. This can be used e.g. to change the package dependencies for conda-forge vs PyPI builds.

Global dependency

Ensure hatch-deps-selector is defined within the build-system.requires field in your pyproject.toml file.

[build-system]
requires = ["hatchling", "hatch-deps-selector"]
build-backend = "hatchling.build"

Build plugin

The build plugin name is selector.

• pyproject.toml

  [tool.hatch.build.hooks.selector]
  default-variant = "foo"
  env-var = <ENV-VAR-NAME>
  
  [tool.hatch.build.hooks.selector.variants.foo]
  dependencies = ["numpy"]

• hatch.toml

  [build.hooks.selector]
  default-variant = "foo"
  env-var = <ENV-VAR-NAME>
  
  [build.hooks.selector.variants.foo]
  dependencies = ["numpy"]

By default, set HATCH_SELECTOR_VARIANT=<VARIANT> to select the dependencies from <VARIANT> as additional project dependencies. This might be used to only pull in certain dependencies when building for PyPI vs conda-forge.

default-variant	str	None	Name of default variant to use if environment variable is unset.
