Thanks for the tips, KnoP.
Maybe I will try it again. Just for the note, I've tried EMACS also
So, few years ago I've made syntax highlighting files and snippets to use with Gedit (so I would have sort of a cross platfor tool).
But Gedit becomes too sluggish when You enable some plugins, so I gave up.*
I bought a license for UEx (UltraEdut for Linux) when it was released, but the first releases were buggy, so I also gave up. I've installed a demo recently, and the things are naturally better, so maybe in a closer future I will try it again.
I will take a look at this Sublime config file.
*EDIT: other reason to abandon Gedit is, to create a new syntax definition, you need to edit a gtk sourcefile, and point that new syntax file, and sometimes it broke when I updated my computers.
