Description
Sending a buffer or a region to octave makes emacs unresponsive until
the evaluation is complete. When the commands are executed manually in
the inferior process buffer, everything works fine.
I tried this on two workstations. I have opened an issue for
spacemacs and was told to report upstream:
https://github.com/syl20bnr/spacemacs/issues/7150
Reproduction guide :beetle:
Start Emacs
write folling in octave mode: for i=1:10 i, pause(1); end
send the buffer to octave with
octave-send-buffer
or mark everything and do
octave-send-region
Observed behavior:
Emacs is unresponsive for 10 seconds. Then a second buffer window opens
with the input lines visible but without output:

Doing ether
octave-send-buffer or octave-send-region again will also trigger emacs
being unresponsive for 10 seconds but this time after 10 seconds the
full output is
displayed at once:
>> for i=1:10
> i,
> pause(1)
> end
i = 1
i = 2
i = 3
i = 4
i = 5
i = 6
i = 7
i = 8
i = 9
i = 10
Expected behavior:
Second buffer opens and i is counting up.
>> for i=1:10
> i,
> pause(1)
> end
i = 1
i = 2
i = 3
i = 4
i = 5
...
This can already be achieved by copying and yanking the commands
manually to the inferior octave process.
