概要
最近、formaterをgithub actionsで使うようになりました。先にそっち?って感じですよね。 手元でも動かせるようにしたのでやり方を備ぼる。
環境
・ubuntu 18.04
・vscode 1.58.2
やり方
1.clang-formatをインストール
sudo apt install clang-format-6.0
2.vscodeの拡張のClang-Formatを入れる
3.vscodeのsetting.jsonに保存時にフォーマットしてくれるように設定を追記する
---中略---- "clang-format.executable": "/usr/bin/clang-format-6.0", "editor.formatOnSave": true, "editor.formatOnType": false, "[cpp]": { "editor.defaultFormatter": "xaver.clang-format" }, }
4.ワークスペース下に.clang-formatのファイルを置く
