I've uploaded yet another revision of multivalues.zip. I decided
to go with "some" for n_m/subrange/subset/i_j/a_z/x_y/etc.
New features:
- some_values/some_of:
if (some_of(3, 5, r) > 3) ... // at least 3 and less than 6 > 3
(I selected the argument order shown because "some" precedes
"of" and "values" and so it rather suggests that the minimum
and maximum should precede the range.
- implementing n_of/n_values and one_of/one_value in terms of
some* which should reduce template instantiations
- some_of/some_values (formerly n_m_of/n_m_values) and
n_of/n_values are now implemented using data members for the
minimum and maximum count to reduce template instantiations
and to support between and exactly
- adds between
if (between(3, 5).items_of(r) > 3) ...
- adds exactly
if (exactly(3).items_of(r) > 3) ...
- all of the above work with pairs of iterators, too (no need to
use boost::make_iterator_range())
- separated code into distinct headers plus one multivalues.hpp
to suck in everything
- added detail subdirectory
This one runs 2016 tests and compiles in just over nine minutes
on my system (still GCC 3.2.3).
There are still some things missing:
- tests for some_of, between, and exactly.
- support for user-defined predicates that only know how to
compare to values and not multivalues
- documentation
If there is reasonable consensus for what we have thus far, among
those interested in this library, I think we should start to work
on some documentation so more people will take a look at the
library.
