Hello!
As a Linux user, I haven't found any GUI for GDB or Clang that I could say I liked. So, as expected by the name of this network, I made my own:
GitHub link
It is an Emacs frontend, similar to the one that comes with it, but that I have tailored to my needs. I've also made it parse the GDB output in a C dynamic module, instead of in Elisp, because I noticed the builtin package was a bit slow when it was fed a lot of output.
I wanted to share it because you may find it useful if you are an Emacs user (or an adventurous person!) and don't have a debugger of choice. :)
