| Subject: | Heredocs break syntax highlight if bogus token detected |
This delightful example I ganked from Test::More.
die <<WHOA;
WHOA! I tried to call ->isa on your $whatami and got some weird error.
Here's the error.
$error
WHOA
Notice that the terminating token is embedded in the heredoc text, but it's not treated as the
terminating token because it's not on a line by itself. Syntax::Highlight::Engine::Kate::Perl
breaks on this case because it thinks the first "WHOA" is the terminating token.
A test case is below.
Cheers,
