Re: syntax region match with braces

[Peter Hodge]

Hello,

I have the same problem with large PHP files, Vim gets confused in the midst of
all the curly braces ... :-S  Unfortunately I'm not yet familiar with the 'syn
sync' commands, partly because they're so hard to test.

You can use a command like ':syn on' to refresh the syntax, and that should
make everything match up properly again.  Also, make sure you don't have the
'display' option added to the wrong syntax items, that can also mess up
matching of { and }.

regards,
Peter
