So I have some custom vi coloring in a syntax file.
This works perfectly (giving a blue background to lines 20-30)
syntax region mytest start="\%20l" end="\%30l"
hi mytest ctermbg=Blue
This does not work at all (attempting to give a blue background to a range that starts with x and ends with y):
syntax region mytest2 start="x" end="y" fold transparent
hi mytest2 ctermbg=Blue
I'm trying to figure out how to give formatting between a start/end point. Any help is appreciated.
