Trying to create syntax definition file for this:
I created 2 states: SectionState and CommentState.
Since SectionState has no closing keyword, it needs to look ahead to the next SECTION keyword to terminate current scope:
PatternValue="\n" LookAhead="[ \n]*SECTION"
There's still a problem: the "!comment" line consumes "\n", so "SECTION s2" is not recognized. To fix this, I changed the EndScope pattern of CommentState from "\n" to "$", so the "\n" is left over to end the SECTION scope.
(Complete syntax definition is attached at the end).
This solution appears OK, but I encountered a NullReferenceException when I do this:
position cursor at the end of "!comment" line, press backspace key 3 times to delete character "t", "n", "e", then re-type "e","n","t".
Would you please take a look? Thanks a lot.
