I’m trying to run rdebug from within emacs using gud (Grand Unified Debugger, or something like that). I see there is a rdebug.el package for this. And using it gives me the ability to set breakpoints by visiting the source file pressing the approppriate key bindings, which is nice. But using GUD in other languages (particularly C) gives more. In particular, it will display a window containing the file being debugged and indicate the current line executing. Currently the rdebug.el package is not doing the dynamic source code display for me. Is my setup wrong? Is rdebug.el not setup to support that? Am I missing something? Thanks. – Jim W. ---

Original Version: “\([^:\n]_\):\([0-9]+\):._\n” Fixed Version: “^Z^Z\([^:\n]_\):\([0-9]+\)._\n” (yes, the first two character of the regexp are control-Z) That fixed it for me. I added the control z’s and removing the second colon and now everything is working fine. This leads me to suspect that the ruby-debug gem and the rdebug.el emacs file are out of sync. My ruby-debug gem is version 0.9.3. There are no version markings in the rdebug.el file. – Jim W. ---

One other thing I forgot to mention. It was not clear to me which rdebug was getting referred to. Probably not the one I have been using (since it works just fine). The other rdebug.el which is distributed in the misc directory of Ruby 1.8.6 is by Martin Nordholts \ I’ve added an SVN $Id$ line in the rdebug.el in ruby-debug’s SVN, so hopefully this will reduce confusion in the future.

My apologies for not seeing this sooner. It has come to my attention that there is a rdebug.el distributed with Ruby 1.8.6. Independently I had been writing/revising my own rdebug.el. and it’s now in ruby-debug’s SVN in the emacs directory. Had I known there was another rdebug.el around, I think I would have tried to avoid that confusion. The rdebug.el in SVN a bit more filled out. It probably can be used with 0.9.3 (since I started writing it in that release). But it really should be used with the ruby-debug that is in SVN since rdebug now supports gdb-style annotations. Also the rdebug.el in SVN probably should be used with Emacs 23. (It might however work in Emacs 22). I’ll write to the author of the other rdebug.el to see what we can do. Perhaps this can be used to support older Emacs versions. As for getting this cleared up so in Ruby 1.8.7, I’m kind of new to this and would appreciate suggestions. At a minimum I will post a tracker ticket. My apologies for the confusion.
