    Installation and use of Atom block comment plug-in multi-comment
    点击之后的界面如下图:
    Installation and use of Atom block comment plug-in multi-comment

1. 默认的块注释 快捷键 修改为:Ctrl + Shift + /

  • 打开项目中的 keymaps\multiline-js-comment.json 文件
    • 修改快捷键为:“ctrl-shift-/”,如下代码:
{
  "atom-workspace": {
    "ctrl-shift-/": "multi-comment:toggle"
  }}
Copy after login
  • 保存代码
    • 快捷键 Ctrl+S保存。

2. 修改默认 注释符 开始标记 /* 后 和 结束标记 */ 前 分别多加了1个空格。

  • 打开项目中的 lib\multi-comment-langs.js 文件
    • 修改如下代码中的openToken (设置 块注释开始标记)和 closeToken(设置 块注释结束标记),并保存:
const languages = [
  {
    name: 'coffeescript',
    test: /^source\.coffee\.?/,
    openToken: '###',
    closeToken: '###',
    /* when used at line start line-scoprDescriptor will override
    so we cheat with leading \t */
    option: { tab: '\\t' }
  },
  {
    name: 'javascript',
    test: /^source\.js\.?/,
    openToken: '/*',
    closeToken: '*/'
  },
  {
    name: 'java',
    test: /^source\.java\.?/,
    openToken: '/*',
    closeToken: '*/'
  },
  {
    name: 'css',
    test: /^source\.css\.?/,
    openToken: '/*',
    closeToken: '*/',
    option: { scanInside: true }
  },
  {
    name: 'php',
    test: /html\.php/,
    openToken: '/* ',
    closeToken: ' */'
  },
  {
    name: 'ruby',
    test: /^source\.ruby\.?/,
    openToken: '=begin',
    closeToken: '=end',
    option: { newline: '\\n' }
  },
  {
    name: 'c',
    test: /^source\.c\.?/,
    openToken: '/*',
    closeToken: '*/'
  }];
Copy after login
  • 本例中:
    • 修改的是PHP语言的。

3. 修改 使用快捷键注释后的光标效果

  • multi-comment插件 注释 选中的内容,发现注释后光标进行了移动(自然的,注释内容选中也就取消了),于是:
    • 在项目中 找到 lib\multi-comment.js 文件在 发现如下代码中 // set cursor position 即最后两行代码 进行了光标移动的操作。
  addComment() {
    const range = this.editor.getSelectedBufferRange();
    const text = this.editor.getTextInBufferRange(range);
    const [open, close] =
    (this.lang.commentTokens.option && this.lang.commentTokens.option.newline) ?
      [`\n${this.lang.commentTokens.open}\n`, `\n${this.lang.commentTokens.close}\n`] :
    (this.lang.commentTokens.option && this.lang.commentTokens.option.tab) ?
      [`\t${this.lang.commentTokens.open}`, `\t${this.lang.commentTokens.close}`] :
      [this.lang.commentTokens.open, this.lang.commentTokens.close];

    this.editor.setTextInBufferRange(range, `${open}${text}${close}`);
    // set cursor position
    const landPosition = pointMove(this.editor.getCursorBufferPosition(), - (close.length - 1), this.editor);
    this.editor.setCursorBufferPosition(landPosition);
  }
Copy after login
  • 将其以上两行代码注释后,发现另外一个问题:在空白行 即没有选中内容的情况下,直接生成注释后,光标没有跳转到 注释开始标记 与 结束标记的中间,解决办法:
    • 将最后两行代码进行如下改造,并保存:

将代码:

	// set cursor position
    const landPosition = pointMove(this.editor.getCursorBufferPosition(), - (close.length - 1), this.editor);
    this.editor.setCursorBufferPosition(landPosition);
Copy after login

修改为:

    if (text === '') {
      // set cursor position
      const landPosition = pointMove(this.editor.getCursorBufferPosition(), - (close.length - 1), this.editor);
      this.editor.setCursorBufferPosition(landPosition);
    }
Copy after login

加粗样式完成以上修改工作后,想要的插件的效果还没有在Atom中立刻生效,因此需要 先关闭Atom,并重新打开。
此时想要的插件的效果就实现了。
