autoscripts

WIP

It basically hasn't been tested, the interface will probably change and the extension hasn't been published. Please file an issue if you would like me to publish this extension and/or if you have feature requests.

Autoscripts is a VS Code extension that takes a list of globs, e.g.

// (that's the default value)
"autoscripts.scripts": [
  "${command:autoscripts.getUserDirectory}/**/*.js",
]

And it executes those scripts when the configuration changes, or when their contents change.

These scripts have access to a special context that can be used to, for instance, output files.

In my case, I have a settings.js file in the Code/User directory which sets some configuration based on the environment and outputs some keybindings.

// Import the `path` module -- since the script is evaluated as a function, a
// regular `import from` statement does not work.
const path = await import("path");

// Update the global configuration based on some env variables.
await vscode.workspace
  .getConfiguration("terminal.external")
  .update("windowsExec", path.join(process.env.SCOOP, "shims/pwsh.exe"),
          vscode.ConfigurationTarget.Global);

// Define the keybindings.
await output("keybindings.json", [
  {
    key: "w",
    command: "dance.run",
    args: {
      code: getFunctionCode(async () => {
        const editor = vscode.window.activeTextEditor,
              prev = editor.selections;

        try {
          await dance.execute('.objects.performSelection', { object: 'word', action: 'select' });
        } catch (e) {
          if ((e?.message ?? '') !== 'no selections remaining') throw e;
        }

        if (editor.selections.every((x, i) => x.isEqual(prev[i]))) {
          await dance.execute(
            ['.search', { input: '\\w' }],
            ['.objects.performSelection', { object: 'word', action: 'select' }]);
        }
      }).trim().split("\n"),
    },
    when: "editorTextFocus && dance.mode == 'normal'",
  },
]);
