Just like migrating from Reddit to Lemmy it’s the same as migrating from Windows to Linux, there’s shortcomings and learning curve and the more I use Lemmy the more I hate about Windows, because unlike reddit Lemmy is open source and open source softwares communities is more popular than proprietary communities and people like to shit on them (and I loved it). (Sorry for horrible English)
I don’t know if you’ve tried Kate, but it does most of this. It can act as an IDE, but it’s first and foremost a text editor, which is similar to Notepad++ (iirc, it’s been a while). The toughest requirement to meet would be
https://docs.kde.org/stable5/en/kate/katepart/highlight.html is the documentation for how you’d do that, and https://invent.kde.org/frameworks/syntax-highlighting/-/tree/master/data/syntax has all of the built-in syntax highlighters.
It also runs on Windows, so you can give it a spin and see what you think. It’s unfortunate that NP++ is tied so directly to Windows APIs, but I wonder how hard it would be to use winelib to make a decent Linux version.
I tried Kate on Linux, and didn’t see that. I’ll look into it again. Thanks for the tip.
I have no clue what it would take to make a Linux version, way over my head haha
