Hello,
I've been fooling around a little with trying to create a language grammar for guitar tablature, and I ran into a problem with matching something like this:
E 0-------|--------|--------| B --0-----|0-------|--------| G ----0---|--0-----|0-------| D ------0-|----0---|--0-----| A --------|------0-|----0---| E --------|--------|------0-|
I should probably know my TERMINOLOGY better in order to do this, but I'm calling this thing a "block" for now. Every document will have 1 or more of these. I attempted to write a rule that would match one these things:
{ name = 'block.tablature'; match = '([A-G].+\n){6}'; }
This doesn't seem to match a section like this, but if I use the find command with that regexp, the "block" is found and selected. What am I missing?

Hello Michael,
From the manual :
Note that the regular expressions are matched against only a single line of the document at a time. That means it is not possible to use a pattern that matches multiple lines. The reason for this is technical: being able to restart the parser at an arbitrary line and having to re-parse only the minimal number of lines affected by an edit. In most situations it is possible to use the begin/end model to overcome this limitation.

I guess this is the limitation you are encountering.
