(minor) Maybe we should rename this var if we're going to use it for
other
purposes, this doesn't really save any typing. Also if we do want the
define maybe we should upper case it so it's more obvious?
Yeah, I tried to think of other ways to do it, but just left it trying
to look like another variable (not to save typing). Well, it can easily
be changed later if a "cleaner" way is decided...
Yeah I would just prefer if it was more obvious that it is *not* a variable ;-)

In the example above, which we have a couple examples of here, we don't
obey the YYFILL macro to detect if we have exceeded our EOF. This
*might* be a problem, but only really depends on if we intend to use the
YYFILL as a solution for exceeding our mmap bounds.
I don't understand what the problem might be? The YYCURSOR < YYLIMIT
check is what the YYFILL has been doing. If you mean after changes
later, as long as the the whole thing is mmap()'d (which I'm assuming
would be the case?), it just "looks" like a standard string, with
terminating '\0', right? And there's no reading past YYLIMIT.
Sorry yeah this wouldn't be a problem currently, but only if we try to fix the
mmap issue by using YYFILL to realloc more space into the buffer. Then that
macro would change to something more complicated. (per my previous replies with
Arnaud)
Have you considered using the lexer STATES and regex's instead of the manual C
code for scanning the rest. It seems like if we have a one-char regex match
for what the C code is doing we could handle this in the lexer without a lot of
manual intervention (need to look at it more, just a thought I had earlier, the
expressions are clearer now with your patch applied) ;-)
