How to resolve the problem when SC-IDE does not show Help Document contents

Questions
1

Hello,

On macOS, after using sclang via

SC-IDE’s help browser sometimes does not display its contents and only shows the following message at the top of the SC help browser:

sending request ......

The only way I found is to reboot the OS.

Is there any way to solve this problem?

I have tried the following two commands in a terminal, but they do not work:

  1. typing

    sudo lsof -i :57120

    It returns for example:

    COMMAND   PID USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
say     25473 prko   21u  IPv4 0x1493e9ac86873831      0t0  UDP *:57120

  2. typing

    sudo killAll say

Did you try SCDoc.renderAll in the IDE?

Sometimes VSCode gets like this and restarting the OS fixes it. I also think logging out the user and logging back in works. What would these processes be doing that would make things work again?

@Sam_Pluta
Um… I am not sure if I did it.
If I encounter this problem again next time, I will test it and report the result here.

Thank you very much!

I cannot evaluate SCDoc.renderAll because sclang seems to be looping. The colour of SCDoc is not blue:

@prko say is a accessibility text-to-speech program shipped with macOS. Maybe disable it?
