Hi Xuefer, all,
Yeah, the re2c patch did change (or add?) a bit for handling the "#"
character (though I haven't investigated your example...).
However, I wanted to report that I just started playing with some changes to
the scanner (re2c), and am seeing weird (or "wired" re: subject :-P) stuff
too. For example, with comments, I noticed that one-line // comments are
lost when they're on the last line, unless followed by ?> (verified with
tokenizer extension; fine before with flex scanner). And multi-line /*
comments that aren't closed don't match either (and no warning about
"Unterminated comment..." anymore). Verified that these rules are never
matched (in those cases) when they should be:
<ST_ONE_LINE_COMMENT>[^\n\r?%>]*{ANY_CHAR}
<ST_COMMENT,ST_DOC_COMMENT>[^*]+
I couldn't figure anything out... Something with YYCURSOR/YYFILL()?
Something getting "stuck" at the last match if it's not in ST_IN_SCRIPTING
state? I don't get it. Marcus, Scott?
Thanks,
Matt
