Implement --bound-options to select one ore more additional pyproject dependencies.

Support optional additional dependencies in pyproject.toml

You may want to make some of your dependencies optional, if they are only needed for a specific feature of your package. In that case, put them in optional-dependencies.

[project.optional-dependencies]
gui = ["PyQt5"]
cli = [
"rich",
"click",
]

Each of the keys defines a “packaging extra”. In the example above, one could use, e.g., pip install your-project-name[gui] to install your project with GUI support, adding the PyQt5 dependency.

this should also work for poetry style groups

// [tool.poetry.group.dev.dependencies]
// pre-commit = ">=2.10"
// setuptools = { version = ">=60", python = "<3.10" }

// [tool.poetry.group.test.dependencies]
// coverage = ">=7.2.0"
// deepdiff = ">=6.3"
// httpretty = ">=1.1"
