Hi ,

I am rite now creating an IDE that executes and gets results from ruby  
process. That contains all of the features of normal IDE.

I am struck to make MY ide to look for the currently executing line  
in ruby intepretter. My task here is to show the currently executing  
line of ruby in my IDE.

Please help me out…

There is a C side equivalent of set\_trace\_func, see rcov, ruby-prof or  
RubyMemoryValidator.  
So you set a callback in a ruby extension, and then you have to
