Hey all!
I wrote a real basic theme to colorize Osiris scripts (.txt files) if you're opening them in VSCode like I am. See the link above or search "Isis" (yes really) on the VSCode extension market.
https://marketplace.visualstudio.com/items?itemName=phalewhale.isis#overviewMakes reading the larger ones quite a bit easier and more parseable. No code completion or navigation tools yet. May work on those later if I have some free time. Feel free to contribute to or fork the repo
here. Hope this helps some of you!
