There has been some discussion recently about creating a Sonic Pi extension for Visual Studio Code as an alternative Sonic Pi GUI.
As this has interested various members of the core team, some explorations have begun into this idea. A proof of concept is taking shape at https://github.com/llloret/sonic-pi-vscode-editor.
Some of the earlier discussion has occurred on Github, at the following links: first at https://github.com/samaaron/sonic-pi/issues/1902 and more recently https://github.com/samaaron/sonic-pi/issues/2371. However, in order to avoid spamming the folks in the original issues there, this thread has been created to continue these discussions in a more suitable place.
For those folks also interested in this idea, either in contributing code to or using a VS Code extension as an alternative interface to Sonic Pi, feel free to follow along with the discussion here.
