vscode语言支持插件开发

安装脚手架

npm install -g yo generator-code

生成插件模板

yo code

配置语言支持

我这里就自定义一种以.da结尾的语言，修改根目录下的package.json文件的contributes处的属性

{
   
  "contributes": {
   
    "languages": [
      {
   
        "id": "da",
        "aliases": [
          "DA"
        ],
        "extensions": [
          ".da"
        ],
        "icon": {
   
          "dark": "logo.png",
          "light": "logo.png"
        },
        "configuration": "language.json"
      }
    ],
    "grammars": [
      {
   
        "language": "da",
        "scopeName": "source.da",
        "path": "grammars.json"
      }
    ],
    "snippets": [
      {
   
        "language": "da",
        "path": "snippets.json"
      }
    ],
  }
}

自动补全括号、注释

在根目录创建language.json文件，填入以下内容，该文件是用来自动补全括号，单行和多行注释用什么符号，我这里注释用-

{
   
    "comments": {
   
        "blockComment": [
            "---",
            "---"
        ],
        "lineComment": "-"
    },
    "brackets": [
        [
            "(",
            ")"
        ],
        [
            "[",
            "]"
        ],
        [
            "{",
            "}"
        ]
    ],
    "autoClosingPairs": [
        [
            "(",
            ")"
        ],
        [
            "[",
            "]"
        ],
        [
            "{",
            "}"
        ]
    ],
    "surroundingPairs": [
        [
            "(",
            ")"
        ],
        [
            "[",
            "]"
        ],
        [
            "{",
            "}"
        ]
    ]
}

语言高亮

在根目录创建grammars.json文件，填入以下内容patterns里面对应repository里面的内容patterns.match就是匹配规则，颜色的话我也没怎么研究明白，交给你们研究了

{
   
  "name": "da",
  "scopeName": "source.da",
  "patterns": [
    {
   
      "include": "#keywords"
    },
    {
   
      "include": "#strings"
    },
    {
   
      "include": "#numbers"
    },
    {
   
      "include": "#comments"
    },
    {
   
      "include": "#variables"
    },
    {
   
      "include": "functions"
    }
  ],
  "repository": {
   
    "keywords": {
   
      "patterns": [
        {
   
          "name": "keyword.control.da",
          "match": "\\b(?:def|print|class|if|for|while|do)\\b"
