highlight breakpoints with pdb

Question

I use pdb with gud to debug python scripts. I am just wondering if there is way to highlight the lines with breakpoints? For example, in some screenshots of gud-gdb, some people seem to have red circles to the left of lines with breakpoints. How to achieve that with pdb? And is there a way to list all breakpoints (like the breakpoints buffer of gud-gdb)?

I actually tried realgud once, and it did have this feature. However, realgud is lacking documentation, and I find it extremely confusing to use. I have very limited knowledge of elisp, so I cannot figure out what is going on without a more detailed guide.

By the way, why gud with pdb does not have the function gud-until?

Thanks.

Answer 1

However, realgud is lacking documentation,

Although I largely agree, there is a wiki How-to-Use which anyone can contribute to. And I suppose you can open an issue to get help.

By the way, why gud with pdb does not have the function gud-until?

pdb does have an until command. Although when I tried it outside of a function it seemed to not work, I suppose there's no reason not it couldn't be included in gud. A guess is that it's not there because until was a more recent addition to gdb and thus gud.

So https://gist.github.com/rocky/7d773de32be146eb7292 has a simple patch that you might be able to apply to gud.el . If you haven't already reported the emacs bug, you can attach this as a suggested remedy. (And if you have reported it I suppose you can still attach it if this hasn't been already addressed.)
