Manage `ignore_missing_imports = true` sections configs automatically

Feature

When I'm adding typing to an existing project, I encounter many libraries that don't have type hints. The easy solution to suppressing these errors is setting ignore_missing_imports = true, but this is not great. The recommended solution, assuming you don't want to write your own stubs, is to create separate sections for each such library. This can be cumbersome to create and manage.

I wrote myself a small tool that generates such configs: https://github.com/indigoviolet/mypy-missing-imports . I think it would be nice for mypy to include something like it, to make the "recommended" path easier to follow.

Pitch

I'm imagining something like

mypy --generate-missing-import-configs <optionally, /path/to/mypy.ini>

which would print out sections for each library identified as a [import] error like

[mypy-foo.*]
ignore_missing_imports = true

If passed a configuration file, it would update the corresponding sections in that file.

I'd be happy to try and add this to mypy if it is useful.

mypy のコマンドライン処理と設定処理から始め、提案されているコマンド mypy --generate-missing-import-configs と、任意の入力 mypy.ini をエントリーポイントとして使用します。意図された動作を確認するため、参照されているツール mypy-missing-imports を確認してください。完了の条件は、ignore_missing_imports = true を含む [mypy-foo.*] のようなライブラリごとのセクションを生成または更新することです。
