在VS Code中将JavaScript的保留关键字斜体化

jab*_*tta 8 javascript textmate visual-studio-code vscode-settings

我试图通过TextMate语言语法使用Visual Studio Code的主题设置创建自定义语法样式。

具体来说,我想将所有JavaScript的保留关键字都斜体化。通过以下设置,我已经设法达到了98%的性能(剩余的注释包括在内)。

不幸的是,我找不到一些规则:

  1. storage包括脂肪箭头符号,这一点我希望包括。我想更具体的,如下面的设置可见,但无法找到更具体的设置constructorconst。另外,这"storage.type.function"是我能找到的最明确的功能设置(需要function关键字,但其中包含粗箭头)。
  2. keyword包括字符,如逻辑运算符等,同样,我希望有。keyword.operator是必要的文本运营商(例如ininstanceof),但是包括字符运算符。
  3. 我找不到eval(严格禁止的)或package(未使用的将来关键字)的规则。

有任何想法吗?

const settings = {
  "editor.tokenColorCustomizations": {
    "textMateRules": [
      {
        "scope": [
          // TODO: missing keywords: package, eval

      // all comment types
      "comment",

      // true, false, null
      "constant.language",

      // import, from, export, default, return, if, for, break, continue, try, catch, finally,
      // throw, default, yield, await
      "keyword.control",

      // TODO: remove operator symbols
      // in, void, delete, instanceof
      "keyword.operator",

      // debugger
      "keyword.other",

      // new
      "keyword.operator.new",

      // enum
      "storage.type.enum",

      // super, this, arguments
      "variable.language",

      // attributes in html, jsx, etc.
      "entity.other.attribute-name",

      // TODO: remove storage.type after finding explicit for constructor, const, let, var
      "storage.type",

      // static, extends, async, private, public, implements
      "storage.modifier",

      // TODO: exclude fat arrow
      // function
      "storage.type.function",

      // class
      "storage.type.class",

      // interface
      "storage.type.interface",
    ],
    "settings": {
      "fontStyle": "italic"
    }
  },
]
  },
};

事实证明,在VS Code中,您可以轻松找到所需的范围。

ctrl/cmd+ shift+ 打开命令搜索p并搜索Developer: Inspect TM scopes。然后,您可以单击想要查找范围的任何符号/单词左侧。


要回答我自己的问题:

  1. 迄今为止,还没有一个明确的范围为constletvarfunction由本身关键字(storage.type.function包括保留字和箭头)。但是,功能箭头存在明确的范围:storage.type.function.arrow。这使我们可以包括整个storage范围,然后明确排除箭头。
  2. keyword.operator.expression 是仅以单词表示的运算符所需的范围。
  3. 对于具体的范围evalpackage尚未公布。您可以指定evalsupport.functionpackagevariable.other.readwrite,但这些范围很广泛,将包括许多其他的结果。

话虽如此,以下列出了斜体显示VS Code中所有JavaScript保留关键字所必需的规则(还包括注释和jsx/ html属性):

"editor.tokenColorCustomizations": {
"textMateRules": [
  {
    "scope": [
      // all comment types
      "comment",

      // true, false, null
      "constant.language",

      // import, from, export, default, return, if, for, break, continue, try, catch, finally,
      // throw, default, yield, await
      "keyword.control",

      // in, void, delete, instanceof
      "keyword.operator.expression",

      // debugger
      "keyword.other",

      // new
      "keyword.operator.new",

      // super, this, arguments
      "variable.language",

      // attributes in html, jsx, etc.
      "entity.other.attribute-name",

      // static, extends, async, private, public, implements
      // constructor, const, let, var, enum, class, function, interface
      // no explicit scopes for constructor, const, let, var
      // also no explicit scope for function without the arrow
      // therefore we enable all storage and explictly exclude the arrow in another scope
      "storage",

      // // no explicit scope for the eval keyword yet
      // // can be targeted with the scope below, but scope is too broad
      // "support.function",

      // // no explicit scope for the package keyword yet
      // // can be targeted with the scope below, but scope is too broad
      // "variable.other.readwrite",
    ],
    "settings": {
      "fontStyle": "italic"
    }
  },
  {
    "scope": [
      // function keyword does not have an explicit scope without the arrow
      // therefore we explictly exclude the function arrow from being italicized
      "storage.type.function.arrow",
    ],
    "settings": {
      "fontStyle": ""
    }
  }
]
