debug 我都是直接上调试器的，用的很爽

不是啊，字符位置什么的，参考sourcemap的实例

字符位置啥意思？行号什么的都有好好保留的

/- -/不仅仅行号啊，例如说
(stacktrace from Node.js REPL)
> global.resfjdorgjdiojdjrgnklsdjghuisdhdofer() TypeError: global.resfjdorgjdiojdjrgnklsdjghuisdhdofer is not a function at repl:1:8 /- HERE !-/ at ContextifyScript.Script.runInThisContext (vm.js:44:33)

哦，我刚刚在吃火锅的时候在廖雪峰的博客里面看了下source map是啥。这个可能得做一会去了，我最近写代码的时间比较少。
可以考虑 @thautwarm

字符位置也需要确定？token那步可能直接丢弃一些字符的。
我个人觉得metainfo就足够了。toJS是指toJSON吗？if so, 并不困难，Parser那步就能完成，比如我这边这个
Stmt[Expr[BinOp[Factor[Atom[Literal[Name [' f ']]
LP [' ( '] Expr[BinOp[Factor[Atom[Literal[Name [' a ']]
LP [' ( '] Expr[BinOp[Factor[Atom[Literal[Name [' b ']]
]
]
]
]
RP [' ) ']]
]
]
]
RP [' ) ']]
]
]
]
]转JSON就是
{"stmt":{"expr":
"<以下省略...字>"
}
}然后debug我也是直接用这个，加上parser步骤的一些过程信息，例如解析上述代码的部分过程信息：
Name <= Name [' a ']
RET
RET
Literal <= Literal[Name [' a ']]
RET
RET
(Closure | Literal) <= (Closure | Literal)[Literal[Name [' a ']]
]
(Closure | Literal) <= (Closure | Literal)[Literal[Name [' a ']]
]

@ice1000 马上就有C#版本了。只要一个语言有列表就好了（逃

/- -/都是大大啊
是咋样丢弃的- -总之出现错误时对了就好

在tokenize那一步就把字符位置存下来就是了，tan$π/2
