I'm playing with conceal in help files to highlight / colour specific text strings. This was working fine until I added the :print: example below.
conceal example
Using this concealed all the : as expected so I tried to escape the : around the word print:
:%s/[^[:print:]]//g :
The original conceal statement was:
syntax match myIgnoreHc /[:#]|[#:]/ contained conceal -Oopswrong original
syn match myhelpCommentHc "[:#]\s.\{-}\s[:#]\s" contains=myIgnoreHc
I changed the match to:
syntax match myIgnoreHc /[:#]\s\S\|\S\s[#:]/ contained conceal
which worked if I wrote the :print: as : :print :
However I'd prefer to escape or tell the parser to ignore the match in certain situations e.g. :: or ## as the :print : isn't what I was after :).
What I'm trying to achieve
I am using the following to hide the opening and closing elements of the match, see image
syntax match myIgnoreHc /[:#]\s\S\|\S\s[#:]/ contained conceal
syn match myhelpCommentHc "[:#]\s.\{-}\s[:#]\s" contains=myIgnoreHc
The : /if line.. example in image does what I want
However if I have a string like
: %s/[[:print:]]//g :
ie second image , then all : are hidden, as expected.
I'm looking for a way to escape the second and third : so they aren't hidden without having to write : %s/[:print:]//g : in the help file like .
: %s/[: :print: :]//g :
in order to achieve the second example
As a workaround I've changed the match command to be
syntax match myIgnoreHc /\^\*\s\|\s\^\*\s/ contained conceal
syn match myhelpCommentHc "\^\*\s.*\s\^\*\s" contains=myIgnoreHc
which works until I write help with a second ^* string
Any suggestions?
