Termdebug for Windows: why a "prompt" buffer instead of a terminal buffer?

[Ubaldo Tiberi]

Hi all,

I have noticed that Termdebug for Windows uses a "prompt" buffer instead of a terminal for the gdb interpreter. 

  - Is there any reason why is that? 

  - Is there any plan to "upgrade" the Termdebug Windows version to use a terminal buffer instead?  

Thanks!

Hi, Tiberi.

You should take a look in the help of 'termdebug-prompt'. There you can find why your Vim version is using prompt instead of terminal.

I hope this message reaches you.

Regards,

I think the reason is, that on Windows using a pty may not always work.
This is briefly mentioned at :h 'termwintype'. If you sure it works for
you (because your Windows is new enough or you have winpty), you could
give it a shot in termdebug with the following patch applied and then
setting the termwintype option:

```patch
diff --git a/runtime/pack/dist/opt/termdebug/plugin/termdebug.vim b/runtime/pack/dist/opt/termdebug/plugin/termdebug.vim
index 50833f0df..8236fc2b0 100644

+ if has('terminal') && (!has('win32') || !empty(&termwintype)) && !use_prompt

I meant, I read ‘termdebug-prompt’ :-)

Ok! Makes sense! Thanks!

But that lead me to the following question: why use gdb mi instead of term_sendkeys, jobs and channel?

That way we would be OS independent and we would also not depend on external tools features (in this case gdb mi) for which we have zero control.

… genuinely asking. :-)

jobs and channels will always be used. Using term_sendkeys sounds
brittle however.


Thanks,

Yeah. In-fact there are apparently no reasons to use term_sendkeys…
