FuckItJS

Javascript错误Steamroller

FuckItJS使用最先进的技术来确保您的JavaScript   无论编译器是否喜欢，代码都会运行。

技术

通过称为Eval-Rinse-Reload-And-Repeat，FuckItJS的过程   反复编译代码，检测错误并切片   脚本中的行。为了生存这样一个暴力的过程，FuckItJS   每次迭代后重新加载自己，允许onerror处理程序   在你编写的代码中捕获每一个错误。

我正在确定lib/my_file.rb中的哪些代码导致Rubinius出现以下错误：

$ ruby lib/my_file.rb 
An exception occurred running lib/my_file.rb
    Error trying to compile /path/to/lib/my_file.rb (Rubinius::CompileError)

目前我正在评论我的部分代码以查看导致错误的原因。是否有可以自动完成此过程的库？
