Context Key Manager

ContextKeyManager lets you register, edit, toggle, and delete custom VS Code context keys (usable in when clauses) directly from commands—no need to write a separate extension each time.

Features

Register: Context Keys: Register creates/overwrites a key & value.
Edit: Context Keys: Edit Value changes stored value/type.
Delete: Context Keys: Delete clears and removes a key.
Toggle: Context Keys: Toggle Boolean flips a boolean key (or auto-converts a non-boolean when invoked with an argument).
Auto re-hydration: previously stored keys restored on activation.

Supported Value Types

boolean (true / false)
string (raw text)
number (parsed with Number())
json (parsed using JSON.parse; falls back to string on parse failure)

Usage

Command Palette (Ctrl+Shift+P) → run Context Keys: Register.
Provide a name (recommend a prefix like user.) and value.
Use the key in keybindings.json, menus, views: "when": "user.myMode == true".
Toggle quickly:

{
  "key": "ctrl+alt+m",
  "command": "contextKeysManager.toggle",
  "args": "user.myMode"
}

Edit or delete via the dedicated commands.

Example Keybinding

{
  "key": "ctrl+alt+k",
  "command": "workbench.action.findInFiles",
  "when": "user.myMode == true"
}

Programmatic Toggle

vscode.commands.executeCommand('contextKeysManager.toggle', 'user.myMode');

Development

cd extension
npm install
npm run compile

Launch with F5 to open an Extension Development Host.

Packaging

npm run package

Install the generated .vsix via: Command Palette → Extensions: Install from VSIX....

Persistence Notes

Keys stored in globalState; clearing VS Code state or using a different profile resets them.
Deleting a key sets its context value to undefined then removes it from storage.
