本文介绍的是 VSCode Snippet 插件,一种代码片段配置插件,可以节省你写样板代码的时间。

Let's talk about the use of Snippet plug-in in VSCode (to improve programming efficiency)

你可能之前学习过 VSCode Snippet 插件,知道它的作用也学习了配置的语法,但是你想不到落地使用的场景。本文也将解决你的这个疑惑~

本文将介绍 VSCode Snippet 的使用介绍、配置语法、引入方式和使用场景。【推荐学习:vscode教程编程教学

VSCode Snippet 插件使用简介

Lets talk about the use of Snippet plug-in in VSCode (to improve programming efficiency)

(图片来自于 VSCode 官网)

如 gif 图所示,当你想编写一段 ajax 代码时,只需要在编辑器里输入 ajax,再点击下 Tab 键,就会为你自动生成 ajax 代码的模板。

Snippet 支持我们配置自己想要的任意代码片段,因此我们可以把项目中常见的代码片段抽出来,提高编程效率。同时可以共享给所在的团队,提高整个团队的编程效率。

Snippet 配置语法

我们拿 antd 组件库举例,比如我们想配置 antd 的 Snippet 代码片段:

Antd Selet 组件代码如下:

<Select
  defaultValue="lucy"
  style={{ width: 100 }}
  onChange={handleChange}
  options={[
    {
      value: &#39;jack&#39;,
      label: &#39;Jack&#39;,
    },
    {
      value: &#39;lucy&#39;,
      label: &#39;Lucy&#39;,
    }
  ]}
/>
Copy after login

对应的 Snippet 配置代码如下:

{
    "antd/Select": {
        "prefix": ["Select"],
        "body": [
            "<Select",
            "    defaultValue={$1}",
            "    style={{ width: ${2|100,200,300,400|} }}",
            "    onChange={${3:handleChange}}",
            "    options={[",
            "        {",
            "            value: $4,",
            "            label: $5,",
            "        }",
            "    ]}",
            "/>"
        ],
        "description": "Antd Select UI 组件"
    }
}
Copy after login

字段含义:

  • prefix 是触发 snippets 的前缀,可以通过数组指定多个

  • body 是填入到编辑器的内容

  • description 是 snippets 的描述

body 部分可以通过 ${} 的方式指定光标位置、顺序、占位字符串、可用的值等

${} 语法简介:

  • 光标跳转:112:

  • 占位符:${1: placeholder}

  • 可选值:${1|text1,text2,text3|}

  • 变量:$变量名

    在模版可编辑位置填入内容的时候,有的时候需要用到选中的值、剪贴板的值、文件名、日期等,这些信息通过 snippets 中支持的变量来取。

    比如:*   TM_FILENAME: 文件名*   TM_CURRENT_LINE: 当前行的内容*   CLIPBOARD: 剪贴板内容*   WORKSPACE_NAME:workspace 的名字*   WORKSPACE_PATH:workspace 的路径*   CURRENT_YEAR:当前年*   CURRENT_MONTH:当前月*   CURRENT_DATE:当前日*   RANDOM: 随机数*   RANDOM_HEX: 6 位随机 16 进制数*   UUID: 唯一 id

    可以取这些变量的值来填入到光标位置,方式就是使用 TM_FILENAMETM\_FILENAME、CURRENT_YEAR 的方式。

Snippets 引入方式:

  • 方式一:直接在项目中生成 .vscode/xxx.code-snippets 文件,格式为本文描述的 JSON 格式,语法如上述介绍。操作方式:

  • 方式二:发布 VS Code 插件:

Sinppets plug-in usage scenarios:

  • #Use some open source component libraries to find out whether the Snippet plug-in already exists, such as antd's snippet plug-in :github.com/bang88/antd…

  • If your project uses an open source framework/component library, this open source project does not have a matching Snippets plug-in , then you who have learned to encapsulate the Snippets plug-in, quickly start using your hard-working little hands, it is time to make some contributions to your team or community~

  • If your project is based on UI component libraries such as antd also encapsulate some public components of their own business, so you can encapsulate a Snippets plug-in for these business-related public components to improve the efficiency of your team

  • In addition to JSX Class components, some commonly used tool functions can also abstract Snippets plug-in code snippets
