No prompt found or ‘comint-prompt-regexp’ not set properly

[vale981]

Hi,
When i run run-jedhy, i get the following error message:

hy-shell--redirect-check-prompt-regexp: No prompt found or ‘comint-prompt-regexp’ not set properly

A little digging around showed, that somehow the hy-shell--redirect-output-buffer is not created.

I am on Emacs 26.3.

What version of Hy are you using?

After running it, is *Hy* buffer created/can you see the Hy process in list-processes? Also try manually sending text eg like (hy-shell--redirect-send "(setv x 1)") then running hy.

Hi, thanks for replying.

I am using hy 0.17.0.

after running run-jedhy, list-processes shows:

Hy              4444    run     *Hy*            /dev/pts/3   hy --spy
Hy Internal     4408    run     *Hy Internal*   /dev/pts/2   hy
server          --      listen  --              --           (network server on /tmp/emacs1000/server)

(hy-shell--redirect-send "(setv x 1)") results in the same error as the above reported:

hy-shell--redirect-check-prompt-regexp: No prompt found or ‘comint-prompt-regexp’ not set properly

me too. problem...

[ekaschalk]

I'm not sure when I will be able to get to this, my job has taken my open source time away.

PRs are welcome.

[vale981]

I understand... My studies have taken mine as well.
I'll look into it, when I find time.

Is anyone aware if this is actually still happening? From #93 it's not clear if this is still a thing.

[alexeiz]

I have to remove the code line that produces this error to make hy-mode work for me. I believe the comint-prompt-regexp test is useless.

[swapneils]

Just want to note I ran into the same issue. I haven't tried implementing #103 or alexeiz's fix, though, so either may be valid solutions.

[Inc0n]

Is there any update for this, for those of us would prefer avoiding manually installing these patch?

[allison-casey]

with alpha 4 out the door now, i'll see what i can do to get hy-mode back up to date

[gehrman]

I just ran into this, and manually applying #103 didn't appear to fix this. I'll try to get a PR up to fix this once I get a bit of time to try and dig in on what's happening.
