Custom build hook¶

This is a custom class in a given Python file that inherits from the BuildHookInterface.

Configuration¶

The build hook plugin name is custom.

pyproject.toml hatch.toml

[tool.hatch.build.hooks.custom]
[tool.hatch.build.targets.<TARGET_NAME>.hooks.custom]

[build.hooks.custom]
[build.targets.<TARGET_NAME>.hooks.custom]

Option	Default	Description
`path`	`hatch_build.py`	The path of the Python file

hatch_build.py

from hatchling.builders.hooks.plugin.interface import BuildHookInterface


class CustomBuildHook(BuildHookInterface):
    ...

If multiple subclasses are found, you must define a function named get_build_hook that returns the desired build hook.

Note

Any defined PLUGIN_NAME is ignored and will always be custom.
