method to fill the background color in document window

[SamC]

Hello，
I want to write a small plugin to change the background color of certain lines of the markdown file for focus view.（like the bookmark，can change the backgroud color of one entire line）
Please give some advise about which api should be used？

BTW, what dose the line in box in the picture below mean？

- plugin Focus Mode exists
- colored line means the https://wiki.freepascal.org/CudaText#Line_states
- API 1: ed.set_prop() with id PROP_MARKED_RANGE: 2-tuple with line indexes of "marked range"; (-1, -1) if range not set.
- API 2: ed.attr()

[main Alexey]

- API 3 (AFAIR, what the Focus Mode plugin uses): ed.dim()

Thanks, ed.set_prop() seems more simple to use，the default color is light blue，may I change it to light yellow？

It is ui-theme color:
editor, marked range BG

Got it, thanks~

Hello,
For the background color，I find in the code block of markdown，the background color will lose in empty row，but when not in the code block，the empty row will also be filled. How to also fill the empty row in code block by PROP_MARKED_RANGE?
Thanks!
what the editor looks like by：ed.set_prop(PROP_MARKED_RANGE,(0,9))

I over written the /data and cuda main program.
The marked range is with no more empty rows. But it seems the original background color in codeblock is disappeared now.
Also, the lexer styles mapping I set seems be reset. Where did it be stored in file？

ops, I made regression in Markdown lexer.
download fixed lexer

and put file to 'data/lexlib'.
