dfa_define_highlight_rule

[Morten Bo Johansen <mojo@xxxxxxxx>]

Hi,

I am trying to construct a dfa color scheme for editing gettext
message catalog files (*.po). Among the syntaxes I'd like to
take a note of are blanks at the beginning and end of lines.
For instance in a line looking like 

   msgid " as audio track, it's a directory "

I'd like to highlight the blanks before and after the '"'.

Likewise I'd like a highlighting when there is only a blank at
either the beginning or at the end of the msgid line.

So I have defined these rules:

   dfa_define_highlight_rule("\"[ \t]+", begblank, name);
   dfa_define_highlight_rule("[ \t]+\"$", endblank, name);
   
This works when the msgid lines look like this
   
   msgid " as audio track, it's a directory "
   msgid " as audio track, it's a directory"  % no blank at end

However in this instance

   msgid "as audio track, it's a directory "  % no blank at beginning

it doesn't work.

If I start a line with a blank and a '"' like this:


 "

it also works.


Could anyone tell me what the regexp should look like in order
to make it work as intended?

 

Regards,


Morten
