- Adds index_if
- Rewrites detail::index_if to use recursive alias stuff
optimized for tuple and basic_tuple
- find_if now uses index_if for Iterables
- at_key now uses index_if for Sequence
- Removes duplicate code and unnecessary special case implementations
- detail::advance_until
- at_key::advance_until
- tuple_tag implementation of find_if
- Uses Foldable instead of Sequence for cases where length is known.
(find_if had a specialization when Iterable and not Sequence)
- Adds test.*.auto.index_if for Sequences
- Adds test support/counter for testing infinite iterables
The headers in this directory provide facilities for automatic unit testing. Basically, each header defines unit tests for an algorithm or a set of related algorithms. To get the tests for these algorithms, simply include the header at global scope. However, before including the header, you must define the following macros:
`MAKE_TUPLE(...)`
Must expand to a sequence holding `__VA_ARGS__`. A valid definition
would be `hana::make_tuple(__VA_ARGS__)`.
`TUPLE_TYPE(...)`
Must expand to the type of a sequence holding objects of type `__VA_ARGS__`.
A valid definition would be `hana::tuple<__VA_ARGS__>`.
`TUPLE_TAG`
Must expand to the tag of the sequence. A valid definition would
be `hana::tuple_tag`.
The following macros may or may not be defined:
`MAKE_TUPLE_NO_CONSTEXPR`
Must be defined if the `MAKE_TUPLE` macro can't be used inside a
constant expression. Otherwise, `MAKE_TUPLE` is assumed to be able
to construct a `constexpr` container.
The following directories contain automatic unit tests, and the following is
sufficient when adding a new automatic unit test (in a file ${FILE}):
DIRECTORIES=(
test/basic_tuple/auto
test/ext/boost/fusion/deque/auto
test/ext/boost/fusion/list/auto

test/ext/std/tuple/auto
test/tuple/auto
)
