[gedit-list] Highlighting assist

[<have@anti.capital>]

Hello friends.

 

I was wondering if someone could assist me to get syntax highlighting working for the file format I have invented, Parallel Square Premusic.

 

I understand there is an entire and complicated XML structure suited for even the most complicated of file formats, but my demands are so tiny that surely I could more quickly get it done by asking those already familiar with it.

 

All I need is for every other pair of characters to be highlighted/colored differently if a line begins with [] (the 'literal square'). This would tremendously facilitate composition and interpretation of my format.

 

Happy Birthday

[]ly  _________-py___-day____________-py___-day____________-py___-day_______...__-py___-day___________
[]ly  __________________to__you!______________to__you!______________dear__________________to__you!____

Here is some example premusic in my format, the familiar "Happy Birthday". The reader is to read not individual characters but pairs; thus it would be enormously useful for them to be colored in an alternating way.
