Anchoring in a regex
syn match tclV "ttk\(\(::\)\?\([[:alnum:]_.]*::\)*\)\a[a-zA-Z0-9_.]*" I only want this to work "ttk" at the start. I know that ^ means the start but I am not sure how to add that (I did try just adding it) to make the regex start with "ttk". Robert

Just put it at the beginning: "^ttk..." just as you would use the dollar-sign at the end to anchor something to the end of the line: "regexp$" -tim

See ":help pattern.txt" for more info on Vim regular expressions (and dont forget the .txt extension, or you'll be brought to a formal syntax definition instead of to the table of contents of the helpfile). Note that $^ in the middle of a pattern usually matches dollar followed by caret, not a linebreak. ( \n matches a linebreak IIUC; but in substitute you must use :s/\n/\r/ to replace a linebreak by itself.) Best regards, Tony.

Thanks Tony and welcome back. : )
I figured out that ttk:: can occur after a left "[" as in "[ttk::" and I
am looking at the others as well.
Is there a way to do an "or" so that I can put ttk in {} [] "" and it be
colored or is there a better way like a region?
