org-babel shell session hangs with gdb
reddit / emacs

I have a shell session in a org file opened, which has started `gdb`
in it.

I am having trouble to execute any gdb commands in shell source blocks
as it would hang, I have to use `C-g` to interrupt the evaluation,
however, in the session buffer file the outputs are all shown once
interrupted.

Is there any work arounds for this?

Thanks in advance!

I would also be interested in writing my own org-babel package for
this, however, as I knew few on this topic, if someone could advise me
on that, it would be also very helpful!

Thanks

I assume that you are using shell code blocks (#+begin_src bash). They
are not tailored to cater interactive commands.

You may need to write a dedicated ob-interactive.el or something. The
starting point is ob-comint.el, which contains common routines to work
with M-x shell

Yes, I am using `#+begin_src shell` actually.

And thanks for the tip of ob-comint, I took the execute functions in
`ob-shell` and rewrote parts of `org-babel-sh-evaluate` as `org-babel-
gdb-evaluate` to make it work!
