Hello, Im probably just missing something simple, but i have a set of keywords defined, and they are being highlighted properly.  However if  a word ends with a keyword its also being highlighted example:


keyword  "OR"   <-- being highlighted

Vendor  <-- the or at the end is being highlighted.

Order  <-- the or is NOT being highlighted.

Hi James,

You are probably missing an Identifier sort of pattern group in your lexer.  You should make an Identifier pattern group that includes anything with a letter/number (standard identifier syntax) and have it low priority in your lexical state.  That will cause things like Vendor to be consumed as an Identifier token.

Not only will that fix your problem (since all the Vendor letters will be consumed), it will also make your lexer faster.  Right now I suspect each character in "Vendor" is lexing as its own token.
