The following updates have been made to the pre-commit template introduced previously.

pre-commit テンプレート の内容を更新。

Main changes

1. Add default_language_version

   By specifying the Python version, you can prevent pre-commit from grabbing an unintended Python version (e.g. 3.13) when building a virtual environment.

   default_language_version:
     python: python3.11
   

2. mypy pre-commit hook support

   Integrating type checking into pre-commit ensures consistent checking locally/CI.

   Also, the commonly used types-* series is specified in additional_dependencies.

   - repo: https://github.com/pre-commit/mirrors-mypy
     rev: 'v1.10.0'
     hooks:
       - id: mypy
         args: [--install-types]

           - types-requests
