Brilliant! I have been imagining for some time how I can contribute to the development of this wonderful community given my limited abilities, so I love knowing that in some way this can be of some use :))
For what it’s worth, I’ve also noticed the following behavior:
- Start supercollider (without booting the server)
- Run “conflicting code” (valid code that produces unjustified errors)
- Observe that the code has been interpreted happily (although, obviously, the audio is not heard)
- Start the server
- Run the “conflicting code” again
- The error now occurs

By the way, I have uninstalled my antivirus client, disabled Windows Defender and manually added exceptions in the Windows firewall for sclang.exe, scsynth.exe, scide.exe and supernova.exe, but this does not solve the problem either
@prko opened a new issue on GitHub to track the problem.
avdrd found a fix for this issue here, but it still persists.
Sorry for the double post.
The file TextLexerBrutal.sc states that
// whether or not to include ^ in any alphabets. Can’t do it right now,
// because ^ will cause unwanted early termination when interpreted.
I think that the issues mentioned earlier are likely due to such an ‘early termination’.
In my user folder, I found a file, editor.js, that could be related to the problem.
“Early termination” refers to:
+ Collection {
myMethod { |sentinel, func|
this.do { |item|
if(func.value(item, sentinel)) {
^item // here is early termination of the loop
}
};
^nil
}
}
That is, ^ behaves this way in a SC class definition. This meaning of ^ is specific to sclang code and should not be assumed to be the same for computer languages in general.
In a string, ^ is just a character, nothing special about it.
The problem in this thread is all taking place in C++, which uses the keyword return to early-exit a function. In C++, there’s no early termination associated with ^.
Interesting that it’s booting the server that messes up the IPC. Those should be independent: IPC is IDE ↔ sclang, booting the server is sclang ↔ server. When the server is running, the IDE does send its own /status requests directly to the server, but that’s through a network socket, which also shouldn’t affect IPC.
