Hi, GCC list!
Apologies if this isn't the right place to ask, but it seems like a good
place to find experts on C++ and Java syntax. If there's a better place
to ask, would somebody give me a pointer, please.
I'm the maintainer of Emacs's CC Mode, which includes modes for C, C++,
Java, etc.
Currently, C++ templates are not handled 100% accurately by C++ mode -
neither are generics in Java mode, for that matter. I want to fix this.
My knowledge of C++ is moderate rather than comprehensive.
So, the question: is it possible to identify with 100% certainty, PURELY
SYNTACTICALLY (i.e. without access to the compiler's symbol table),
when "< ... >" is a pair of template (C++) or generic (Java) brackets?
I'm thinking of things like
foo (a < b, c > d);
I think this is unambiguously a function call with 2 parameters, the
expressions "a < b" and "c > d". It cannot be be one with 1 parameter
beginning with the template invocation "a < b , c >". Or can it?
I believe that a pair of template brackets cannot enclose a semicolon,
for example.
Another related question: although there is no maximum bound on how far
apart template/generic brackets can be, I believe that in practice, they
are never that far apart (a few hundred bytes max, perhaps). Is this, in
fact, the case?
A cc: to [EMAIL PROTECTED] would be most appreciated.
Thanks in advance for any and all help!
