Ported test for std::string non-members operators (+, ==, != , <=, >=,
<, >) are here:
http://people.apache.org/~antonp/stdcxx05252006b/
Also there are required differences to strings.h/.cpp.
I noticed two problems with non-members:
1) _rw_sigcat forms incorrect formatted strings for non-members. The
cause is in additional shift in the for cycle:
for (size_t argno = 0; argmap >>= Ids::arg_bits; ++argno) {
I guess it was done to process "self" flag bits for members.
I implemented workaround using NON_MEMBER_(N) (f, void, arg1, arg2, ...)
instead of NON_MEMBER_(N - 1) (f, arg1, arg2, ...) , i.e. definnig the
following:
#define NON_MEMBER_2(f, a, b) \
FID_2 (f, a, b) = SIG_3 (f, void, a, b)
But maybe there is another way to solve this problem...
2) The "=" symbol in _rw_func_names array brokes the command line
arguments parsing. I tried "operator==", "operator!=", etc and this
didn't work and
I used synonyms: "operator_equal", "operator_not_equal", etc instead. Is
there any way to allow the "=" using in operator's names?
Change Log:
2006-05-25 Anton Pevtsov <[EMAIL PROTECTED]>
* 21.strings.h (FuncId): Added new elements for non-members
(NON_MEMBER_N): Changed to use SIG_N + 1 (f, void, a, ...) to
workaround problem with additional shift in _rw_sigcat.
(OverloadId): Added new elements for non-members operators.
* 21.strings.cpp (_rw_func_names): Added new elements for
non-members operators - synonyms to avoid problems with
command line arguments parsing
(_rw_setvars): Updated to use full template arguments lis for
UserAlloc,
method "header" format updated for non-members, added new cases
for new OverloadId elements.
Also I suggest to extend the FuncId to 6 bits: there are at least 6
methods left (from the capacity test, begin(), end(), etc).
What do you think about this?
Thanks,
Anton Pevtsov
