I have made a start on a syntax-highlighter for atom, to make editing urscript a bit easier on the eyes.
it can be found as urscript-formatter in atom, and i’ll be looking to improve it when I have the time
We use VSCode for our script development and use this plugin for VSCode which is pretty good, not totally complete but most of the way there.
Also, I know in Atom you can extend an existing language linter to accept URScript, I have done this with a Python linter before so that URSCript would get syntax highlighting but there are some language differences between then two and it would throw some errors that you could just ignore
