VS Code 扩展

VS Code 扩展是一种可帮助您自定义和扩展 VS Code 的软件。您可以使用扩展来添加新功能、更改现有功能或只是改善您的整体开发体验。

实现中英文空格扩展

创建一个 VS Code 扩展来实现中英文间自动加空格的过程相对简单。您需要做的就是：

创建一个新的 VS Code 扩展项目。
在您的扩展的 package.json 文件中添加以下代码：

{
  "name": "add-space-between-chinese-and-english",
  "version": "1.0.0",
  "description": "Adds a space between Chinese and English characters in the editor.",
  "main": "./extension.js",
  "activationEvents": [
    "onLanguage:javascript",
    "onLanguage:typescript",
    "onLanguage:python"
  ]
}

在您的扩展的 extension.js 文件中添加以下代码：

// The main function of the extension.
function activate(context) {
  // Register a command that will be called when the user presses the shortcut.
  context.subscriptions.push(vscode.commands.registerCommand('add-space-between-chinese-and-english', () => {
    // Get the active text editor.
    const editor = vscode.window.activeTextEditor;

    // If there is no active text editor, do nothing.
    if (!editor) {
      return;
    }

    // Get the current selection.
    const selection = editor.selection;

    // Get the text of the current selection.
    const text = editor.document.getText(selection);

    // Add a space between each Chinese and English character.
    const newText = text.replace(/([a-zA-Z])([0-9a-zA-Z\u4e00-\u9fa5]+)/g, '$1 $2');

    // Replace the current selection with the new text.
    editor.edit(editBuilder => {
      editBuilder.replace(selection, newText);
    });
  }));
}

// This function is called when the extension is deactivated.
function deactivate() {
}

// Export the activate and deactivate functions.
module.exports = {
  activate,
  deactivate
};
