如何在自定义VSCode语言中引用注入语法

Question

下面是前言。说明此问题的演示项目可在以下位置找到：https://github.com/kirksl/so60384141

我可以在原生VSCode语言中引用注入语法

指定此(package.json)

        "grammars": 
        [
            {
                "scopeName": "source.js.mylang",
                "path": "./syntaxes/mylang-js.tmLanguage.json",
                "injectTo": ["source.js"]
            }
        ]

和这个(./syntaxes/mylang-js.tmLanguage.json)

{
  "scopeName": "source.js.mylang",
  "injectionSelector": "L:source",
  "patterns": [
    {
      "include": "#todo-keyword"
    }
  ],
  "repository": {
    "todo-keyword": {
      "match": "TODO",
      "name": "keyword.todo"
    }
  }
}

我看到了这个(.js文件，原生JS)

到目前一切尚好。

然而，我似乎不能在我的自定义语言中引用相同的注入语法，如下所述。带有三重引号的围栏代码块应该利用它。

更新，现在，这个(package.json)

        "languages": [
            {
                "id": "mylang",
                "aliases": ["Mylang", "mylang"],
                "extensions": [".mylang"],
                "configuration": "./language-configuration.json"
            }
        ],
        "grammars": 
        [
            {
                "language": "mylang",
                "scopeName": "source.mylang",
                "path": "./syntaxes/mylang.tmLanguage.json",
                "embeddedLanguages": {
                    "meta.embedded.block.javascript": "javascript"
                }
            },
            {
                "scopeName": "source.js.mylang",
                "path": "./syntaxes/mylang-js.tmLanguage.json",
                "injectTo": ["source.js"]
            }
        ]

并另外指定(./syntaxes/mylang-js.tmLanguage.json)

    "fenced-expression": {
      "begin": "(^|\\G)\\s*[\"]{3}\\s*$",
      "end": "(^|\\G)\\s*[\"]{3}\\s*$",
      "contentName": "meta.embedded.block",
      "beginCaptures": {
        "0": {
          "name": "string.quoted.triple.mylang"
        }
      },
      "endCaptures": {
        "0": {
          "name": "string.quoted.triple.mylang"
        }
      },
      "patterns": [
        {
          "begin": "^(\\s*)(?=[\\S&&[^{<\\[]])",
          "while": "^(?!\\s*[\"]{3}\\s*)",
          "contentName": "meta.embedded.block.javascript",
          "patterns": [
            {
              "include": "source.js"
            }
          ]
        }
      ]
    }

我看到了这个(.mylang文件，JS突出显示，TODO未突出显示)

最后，我只展示了一些管道，以便能够高亮显示我正在寻找的内容

如果我将"include": "source.js"切换到"include": "source.js.mylang"

    "fenced-expression": {
      "begin": "(^|\\G)\\s*[\"]{3}\\s*$",
      "end": "(^|\\G)\\s*[\"]{3}\\s*$",
      "contentName": "meta.embedded.block",
      "beginCaptures": {
        "0": {
          "name": "string.quoted.triple.mylang"
        }
      },
      "endCaptures": {
        "0": {
          "name": "string.quoted.triple.mylang"
        }
      },
      "patterns": [
        {
          "begin": "^(\\s*)(?=[\\S&&[^{<\\[]])",
          "while": "^(?!\\s*[\"]{3}\\s*)",
          "contentName": "meta.embedded.block.javascript",
          "patterns": [
            {
              "include": "source.js.mylang"
            }
          ]
        }
      ]
    }

我看到了这个(.mylang文件，JS没有突出显示，TODO突出显示)

Answer 1

您还需要将mylang-js.tmLanguage.json注入到source.mylang中(injectTo仅适用于顶级作用域名称，请参阅解释here)：

{
    "scopeName": "source.js.mylang",
    "path": "./syntaxes/mylang-js.tmLanguage.json",
    "injectTo": ["source.js", "source.mylang"]
}

然后它看起来就像预期的那样工作：

此外，您还必须调整injectionSelector，以确保TODO突出显示仅应用于嵌入式JS块的注释中：

"injectionSelector": "L:comment.line.double-slash.js"
