Sorry for assuming without trying them all.
My recent successes are installing LSP/vscode on MacOS, Linux and Windows, and installing the sc kernel for Jupyter Lab on MacOS, Linux and Windows. Both do not support Windows.
More than 13 years ago, when I was a beginner, I tried using scel and scvim, but returned to the official binary release because they are not as convenient as SuperCollider.app. I have tried to install them from time to time over the last few years, but SC-IDE is still my main tool. As for scnvim, I have not even been able to install it successfully on MacOS. The installation instructions are a bit difficult to follow. So I have not tried to install it on other OSes. (I am not much of a beginner. I can build SuperCollider from source on MacOS and Ubuntu).
To replace text across files in SC project files, including my writing in schelp file format, I had used Atom, Brackets, BBEdit, TextWrangler, Dreamweaver, Sublime Text and Textmate, but now only use VSCode.
I am really happy with LSP/vscode and sc kernel for Jupyter Lab.
Especially for large projects I would like to switch to LSP/vscode completely, but I think in LSP/vscode and sc kernel for Jupyter Lab something should be reworked to completely replace SC-IDE.
(I am not judging other editors. Emacs with i3 seems really great to me, but I have not tried it.)
Until then, I think it is not bad to post in this thread, because
- a survey in 2019 showed that many users are using SC-IDE at that time: Which IDE do you use?
- I think there are still many users who rely on SC-IDE.
- I also see that there are new PRs for SC-IDE on GitHub. I would like to see these PRs accepted.
