Haxe/Nodejs调试 - 源映射

Question

如何在nodejs上启用源映射？我希望堆栈跟踪映射到.hx文件而不是生成的.js文件.

Main.hx:

package;

class Main
{
    public static function main()
        throw "test";
}

build.hxml:

-lib hxnodejs
-cp src
-js bin/index.js
-main Main

输出:( cd bin && node index.js)

/Users/kevin/Codes/testnodejs/bin/index.js:10
    throw new js__$Boot_HaxeError("test");
    ^
Error: test

Answer 1

1. 从npm安装"source-map-support"

   npm install source-map-support
   

2. -debug在hxml中启用(以便Haxe生成源映射文件)

3. install()在程序的最开始部分运行:

   js.Lib.require('source-map-support').install();
   

4. 将wrapCallSite函数分配给haxe.CallStack

   haxe.CallStack.wrapCallSite = js.Lib.require('source-map-support').wrapCallSite;
