How do I highlight words with $?

Alv_ · Aug 10, 2005#12005-08-10T04:48+00:00

Variables in PHP are represented by a dollar sign ($). How do I get the full word to be highlighted?

Presently I could just only get the dollar sign to be highlighted. The word remains black.

E.g.
$var=1;
$result == 'true';

Thanks in advance.

This is described in the Keywords beginning with a Sub String section of the help for syntax highlighting. Add a color group for variables and use ** to colorize all words beginning with a $. e.g.

Code: Select all

/C5"Variables"
** $

You'll also need to ensure that $ is not listed as a delimiter.

Is there a way to highlight only the first 'n' number of characters using the '**' syntax? For example, I might have data=test or data=prog1 and I only want the 'data=' to be highlighted.

Add = to the delimiter characters /Delimiters = and the = additionally to the color group with the substring definition. Then only "data" will be highlighted by the substring specification and = will have the same color. Highlighting only n characters of a substring is not possible.
