How do I make vim syntax highlight a whole line?

I'd like to have vim highlight entire lines that match certain patterns. I can get all the text in a line to highlight (by doing syn match MyMatch "^.*text-to-match.*$"), but it always stops at the end of the text. I'd like to to continue to the end of the term, like highlighting CursorLine.

I've tried replacing $ with a \n^, hoping that would wrap it around. No change. (I didn't actually expect this would work, but there's no harm in trying.) I also tried adjusting the syn-pattern-offset (which I read about here: http://vimdoc.sourceforge.net/htmldoc/syntax.html#:syn-pattern). Long story short, adding he=he-5 will highlight 5 fewer characters, but he=he+5 doesn't show any extra characters because there aren't characters to highlight.

This is my first attempt at making a vim syntax and I'm relatively new to vim. Please be gentle and include explanations.

Thanks!

(edit: Forgot to include开发者_Go百科, this is a multiline highlight. That probably increases the complexity a bit.)

It's not very adaptive as the filename (buffer) and line to full row highlight needs to be explicitly identified, but apparently the sign command can be used:

It is possible to highlight an entire line using the :sign mechanism.
An example can be found at :help sign-commands
In a nutshell:

:sign define wholeline linehl=ErrorMsg
:sign place 1 name=wholeline line=123 file=thisfile.txt

Obviously, you should pick a higlight group that changes the color of the background for the linehl argument.

From the documentation on syn-pattern:

The highlighted area will never be outside of the matched text.

I'd count myself surprised if you got this to work, but then again, Vim is always full of surprises.

could also try :set cursorline :set cursorcolumn change colors like this: :hi cursorline :hi cursorcolumn using the usual term=, ctermfg=, ctermbg= etc see this answer VIM Highlight the whole current line
