Matalb command shell becomes slow when there are too many lines. Is it possible to clear the buffer to speed up? I don't want to kill the buffer because it will lose the command history. Thanks Jiaen |

Hi Jiaen, Matlab-shell is derived from comint-mode, so you can use "C-c M-o" to clear the buffer. This runs `comint-clear'. You do not lose your history. However comint should not be slowing down in the first place. It stays snappy for me unless I accidentally dump several dozen megabytes of text into buffer by forgetting a semicolon at the end of the command.

Hi Karthik Thanks a lot! It's really helpful to know this function.

Hi Could it be due to very long lines (not the number of lines)? Do you have an example, maybe a MATLAB script I could run to take a look at the issue?

What Karthik describes about dumping too much text in the shell happened to me. Maybe it better describes the issue. I'm not sure if a very long line can cause the slowdown. Unfortunately I don't have a concrete example to test this. Thanks, John.

I have also experienced slowdown with extremely long shell buffers (hundreds of thousands of lines), which I managed to address by disabling undo. I added the following to my init file to do so automatically: (add-hook 'matlab-shell-mode-hook 'buffer-disable-undo) This does not affect command history.

Thanks Roman. Have you experienced slow down after clearing the command buffer? I haven’t tested this since I learned the clearing trick.
