Feature request: support realgud

[jluttine]

Would it be possible/reasonable to add support for realgud?

I guess it's a better debugging front-end for interacting with external debuggers than built-in(?) GUD.

[jluttine]

Realgud would probably add support for ipdb (see #5907) among other things.

I haven't tried realgud, but it sounds really cool 👍

[nixmaniack]

It's really nice, I have had it before Spacemacs, seems I lost it in migration to Spacemacs!

[jluttine]

I'm trying to write a layer for realgud (my first layer ever). I'll write about my progress here so others can help/comment.

I wrote a simple (private) layer which uses realgud package. After activating the layer and restarting spacemacs, I got a loooong list of compiling errors: realgud/realgud#77

Is this something I should be worried about and should it be fixed or is it something normal?

[jluttine]

I'm trying to load the library as told in the realgud instructions (M-x load-library realgud), but I get error: Cannot open load file: no such file or directory. So, I suppose the installation didn't work. Now I'm stuck.

[robbyoconnor]

Why not make a pull request ;)

[bmag]

@jluttine can you upload the layer to github so we can see and comment? As @robbyoconnor suggested, you can make a pull request and mark it as WIP

[jluttine]

Thanks for the suggestion. I made a pull request here: #5915

I realize the PR is stuck but just expressing my interest in this layer.

[AndreaOrru]

+1 for this.

[pedrovanzella]

This would be great too.

realgud is now part of the c-c++ layer.

[bkudria]

@syl20bnr Why that layer? realgud has support for many different debuggers: https://github.com/realgud/realgud/wiki/Debuggers-Supported

[robbyoconnor]

yeah this has power beyond just c/c++...

[yubrshen]

If realgud is part of c-c++, but I need to use it with python, how can I start realgud? Without starting C++ mode, in Python mode, realgud is not available? To use, should I start C++ mode first?

[yubrshen]

Even with starting C++ mode, I still could not find realgud (by M-x realgud)

[simpsonw]

@yubrshen I couldn't find it either. I looked in packages.el for the c-c++ layer. @syl20bnr did realgud go missing at some point or am I just looking in the wrong spot?

[simpsonw]

@yubrshen I think you may have to check out the develop branch of Spacemacs to get realgud in the c-c++ layer.

[sbseltzer]

It does seem the develop's c-c++ layer is missing realgud. Though I agree it doesn't really belong there since the point is to support multiple debuggers. Still, c-c++ is a start.

+1, real gud supports much more debugger that default gud.
Please add the support.

Please keep real-gud alive because it is going to support lldb. And LLDB is the default debugger on Mac now. It's tricky (and steps are constantly changing) to make GDB working on Mac.

(Emacs default gud can never support lldb, because the boss of GNU does not allow Emacs officially supports LLDB since he thinks LLDB is a "systematic attack" to Emacs/GNU. If you "emacs lldb" online, you will find more.)

On the develop branch RealGUD support has been relocated to the debug layer. You will need to add this layer to your .spacemacs in order to be able to use RealGUD in the c-c++ mode.

realgud-lldb is in MELPA now.
