Version build hook

This writes the project's version to a file.

Configuration

The build hook plugin name is version.

=== ":octicons-file-code-16: pyproject.toml"

```toml
[tool.hatch.build.hooks.version]
[tool.hatch.build.targets.<TARGET_NAME>.hooks.version]
```

=== ":octicons-file-code-16: hatch.toml"

```toml
[build.hooks.version]
[build.targets.<TARGET_NAME>.hooks.version]
```

Option	Description
`path` (required)	A relative path to the desired file
`template`	A string representing the entire contents of `path` that will be formatted with a `version` variable
`pattern`	Rather than updating the entire file, a regular expression may be used that has a named group called `version` that represents the version. If set to `true`, a pattern will be used that looks for a variable named `__version__` or `VERSION` that is set to a string containing the version, optionally prefixed with the lowercase letter `v`.
