Configuration

The build hook plugin name is mypyc.

• pyproject.toml

  [tool.hatch.build.targets.wheel.hooks.mypyc]
  dependencies = ["hatch-mypyc"]

• hatch.toml

  [build.targets.wheel.hooks.mypyc]
  dependencies = ["hatch-mypyc"]

File selection

By default, all files included using the standard file selection options with a .py extension will be targeted. You can narrow what files to compile to an even smaller subset with the include/exclude options, which represent Git-style glob patterns.

[build.targets.wheel.hooks.mypyc]
include = ["/src/pkg/server"]
exclude = ["__main__.py"]

Mypy arguments

You can specify extra Mypy arguments with the mypy-args option.

[build.targets.wheel.hooks.mypyc]
mypy-args = [
  "--disallow-untyped-defs",
]

Options

You can specify options that affect the behavior of mypycify.

[build.targets.wheel.hooks.mypyc.options]
opt_level = "3"

Note:

• the target_dir option is used internally and therefore has no effect

Missing types

If you need more packages at build time in order to successfully type check, you can use the following options where you configured the plugin:

• dependencies - add more dependencies alongside hatch-mypyc
• require-runtime-dependencies - set to true to include dependencies defined in the project.dependencies array
• require-runtime-features - set to an array of named dependency groups that are defined in project.optional-dependencies
