如何使用JavaScript解析一個.RC文件

我想解析從.RC（資源定義文件）到JSON的數據使用js與簡單的fs.readFile函數，但是我得到SyntaxError：無效或意外的標記。目前我找不到解析這種類型文件的其他解決方案，請爲我提供輸入。以下是.RC示例。如何使用JavaScript解析一個.RC文件

#include "shapes.h" 

ShapesCursor CURSOR SHAPES.CUR 
ShapesIcon ICON SHAPES.ICO 

ShapesMenu MENU 
{ 
    POPUP "&Shape" 
    { 
    MENUITEM "&Clear", ID_CLEAR 
    MENUITEM "&Rectangle", ID_RECT 
    } 
}

我發現節點的包叫做「Jison」，這是建立在JavaScript解析器類似於「PegJS」的API，但是我無法找出需要爲我的文件中寫的語法如果它支持文件類型，也鍵入。該分析的結構看上去就像，

{ 
    "directive": [ 
     "include", 
     "shapes.h" 
    ], 
    "data": [ 
     { 
      "name": "ShapesCursor", 
      "values": [ 
       "CURSOR", 
       "SHAPES.CUR" 
      ], 
      "children": [] 
     }, 
     { 
      "name": "ShapesIcon", 
      "values": [ 
       "CURSOR", 
       "SHAPES.ICO" 
      ], 
      "children": [] 
     }, 
     { 
      "name": "POPUP", 
      "values": [ 
       "&Shape" 
      ], 
      "children": [ 
       { 
        "name": "MENUITEM", 
        "values": [ 
         "&Clear", 
         "ID_CLEAR" 
        ], 
        "children": [] 
       }, 
       { 
        "name": "MENUITEM", 
        "values": [ 
         "&Rectangle", 
         "ID_RECT" 
        ], 
        "children": [] 
       } 
      ] 
     } 
    ] 
}

[JSON]（http://www.json.org/）是一個良好定義的格式（檢查[MDN DOC]（https://developer.mozilla.org/en-US/docs/ Web/JavaScript/Reference/Global_Objects/JSON）），我不確定這些文件是否存在JS解析器。你有來自另一種語言的示例實現嗎？請收集更多細節和[編輯]你的問題。 – LEI

我在節點中找到一個名爲'Jison'的包，這是一個用於在JavaScript中創建類似於'PegJS'的解析器的API，但是我找不出需要爲我的文件類型編寫的語法，如果它支持文件類型。 –

如果你想覆蓋一個庫及其邊緣案例，編寫你自己的解析器可能是一個巨大的任務。也許提供一些鏈接到資源文件doc。 – LEI

下面的語法可用於分析資源描述文件到JSON。
