I'm still looking for a Linux replacement with syntax highlighting like Notepad++. Kate is good, even better performance, but no UI for highlighting. The coding for syntax is way over my head from what I saw.
Kate does have syntax highlighting. You have to configure it once in a JSON and that's it.
I have no clue where to start with that.
Looks like it's actually available by default. The json thing is for the language server which does linting and autocomplete.
To activate syntax highlighting just select the language of your choice by pressing the language name on the very bottom right corner of the window and choose the correct language.
