如何使用键盘闯入运行Rails应用程序的ruby-debug？ [英] How do I use the keyboard to break into ruby-debug running a rails app?

问题描述

我正在Rails 2.3上使用 bundle exec rdebug脚本/服务器运行ruby-debug。当我按 Ctrl-C 时，它将退出整个程序和调试器。我希望它停止程序的执行并使我进入调试器会话。

I'm running ruby-debug with bundle exec rdebug script/server on Rails 2.3. When I press Ctrl-C, it exits the entire program and the debugger. I want it to stop execution of the program and bring me into a debugger session.

我尝试了 catch中断，但是它没有用。当我使用 Ctrl-C 停止rails时是否会发生调用异常的情况？还是有另一种方法？

I tried catch Interrupt but it didn't work. Is there an exception that gets called when I stop rails with Ctrl-C that would be good to use for this purpose? Or is there another way?

我想要的是等同于按Visual Studio中的Break（暂停）按钮（我尚未使用Rails IDE做到这一点） ）。

What I want is the equivalent of pressing the Break (pause) button in Visual Studio (I haven't yet done this with a Rails IDE).

推荐答案

我建议撬。安装gem，然后将其粘贴到要调试的代码中即可。

I recommend pry over ruby-debug. Install the gem and then you can just stick this into your code where you want to debug:

binding.pry
