visual-studio-code - 如何在 VSCode 语法高亮的 textmate 语言定义中定义模板字符串？

Question

我有一个包含以下组件的脚本：

• 条款：/[a-z][a-z0-9]*(?:-[a-z0-9]+)*/
• 字符串：<.+>
• 数字：\d+

但是，字符串也可以是“模板字符串”，并且在内部具有嵌套的术语/字符串/数字。它们由{...}大括号分隔，如下所示：

term <string {term(another-term, 123)}>

如何让 VSCode 正确突出显示模板字符串内大括号内的内容？我用它来生成一个项目，它给了我这个<mystring>.tmLanguage.json：

{
  "$schema": "https://raw.githubusercontent.com/martinring/tmlanguage/master/tmlanguage.json",
  "name": "myscript",
  "patterns": [
    {
      "include": "#terms"
    },
    {
      "include": "#strings"
    },
    {
      "include": "#numbers"
    }
  ],
  "repository": {
    "terms": {
      "patterns": [
        {
          "name": "term.control.myscript",
          "match": "\\b([a-z][a-z0-9]*(?:-[a-z0-9]+)*)\\b"
        },
        {
          "name": "term.context.myscript",
          "match": "\\b(\\{[^\\}]+\\})\\b"
        }
      ]
    },
    "numbers": {
      "patterns": [
        {
          "name": "constant.numeric.integer.myscript",
          "match": "\\b(\\d+)\\b"
        },
        {
          "name": "constant.numeric.decimal.myscript",
          "match": "\\b(\\d+\\.\\d+)\\b"
        }
      ]
    },
    "strings": {
      "name": "string.quoted.double.myscript",
      "begin": "<",
      "end": ">",
      "patterns": [
        {
          "name": "constant.character.escape.myscript",
          "match": "\\\\."
        }
      ]
    }
  },
  "scopeName": "source.myscript"
}

但是，我得到了这个：

我以前从未为编辑器做过语法高亮，所以不确定在哪里真正调试。

我通过使用 textmate 语言语法中的特殊范围来完成这项工作：

      "include": "#strings"
    },
    {
      "include": "#numbers"
    }
  ],
  "repository": {
