vscodeでemacsのC-sでの検索の体験を再現したい

以下のような形で動かしたい

ctrl + s  => find
(findのダイアログが開いた状態で) ctrl + s => find next
(findのダイアログが開いた状態で) ctrl + r => find previous

podhmo

これ入れるだけで解決した (インストールし忘れてた）

そもそもkeyboard shortcutsの設定は

[!TIP]
特徴的なflavorのキーマップを用意する拡張はkey map extensionという名前のよう

ctrl + shift + p で Developer: Toggle Keyboard Shortcuts Troubleshooting を開くとなんか教えてくれそう

設定ファイル

keybindings.jsonっぽい

whenってどんな種類があるんだろう？この辺？

例えばこんな感じ

Context name	True when
Editor contexts
editorFocus	An editor has focus, either the text or a widget.
editorTextFocus	The text in an editor has focus (cursor is blinking).
textInputFocus	Any editor has focus (regular editor, debug REPL, etc.).
inputFocus	Any text input area has focus (editors or text boxes).

context keyの調べ方

おそらく、Developer: Inspect Context Keys で調べられる。

Developper: Toggle Developer Tools をする必要がある

クリックするとなんか手に入る

podhmo

whenで利用できるoperator

Operator	Symbol	Example
Equality	==	['editorLangId == typescript']
Inequality	!=	['resourceExtname != .js']
Or
And	&&	['textInputFocus && !editorReadonly']
Matches	=~	['resourceScheme =~ /^untitled$

podhmo

remove keybindingは-<name> みたいな感じで登録されるみたい。

    {
        "key": "ctrl+h",
        "command": "-emacs-mcx.deleteBackwardChar",
        "when": "editorTextFocus && !editorReadonly"
    },
    {
        "key": "ctrl+h",
        "command": "-deleteLeft",
        "when": "textInputFocus"
    }

💭 個人的にはCtrl+hでの削除を使わないし、いっそのことコマンドパレットの起動をこれにしちゃいたい。

Hidden comment

podhmo

keybindings.json がこの辺で設定されている。コマンドは自作なのかな？

podhmo

package.jsonでcommandが定義されてる

podhmo

このへんでコマンドが登録されてる

podhmo

runCommandはこれ

podhmo

emulatorの持つcommand registryへの登録はこれ

podhmo

コマンドの実装はこれ

podhmo

editor.action.nextMatchFindAction　が使われる？

vscode側のコード

podhmo

これでCtrl + s後のctrl + sで再検索が効くようになるのかな

実際 toggle keyboard shortcuts をtraceしてみると
