This changeset fixes a huge pile of problems, as indicated in the
error log of the Doxygen run after merging all the recent Doxygen improvements
unfortunately, auto-linking does still not work at various places.
There is no clear indication what might be the problem.
Possibly the rather unstable Sqlite support in this Doxygen version
is the cause. Anyway, needs to be investigated further.
incidentally, this uncovered yet another unwanted narrowing conversion,
namely from double via gavl_time_t to TimeValue or alternatively
from double via FSecs (= rational<long>) to Duration.
As in all the previos cases, actually the compiler is to blame,
and GCC-5 is known to get that one right, i.e. let the SFINAE fail
instead of passing it with a "narrowing conversion" warning.
Note: the real test for command binding with immutable types
can be found in BusTerm_test
based on the new generic tuple builder, we're now able to
add a new binding function into the command implementation
machinery, alongside the existing one. As it stands, the
latter will be used rather by unit tests, while the new
access path is what will be actually taken within
the application, when receiving argument binding
messages dispatched via the UI-Bus.
since this is a quick-n-dirty workariound, until we're using GCC-5,
I'll err for the simple and safe side and disallow any conversion
from LuidH do some algebraic data type. The problem arises,
sincd LuidH defines a conversion to size_t, which depends
on the platform. So, without checking the actual NumericLimits,
there is no way we can allow a conversion to size_t in a
hard wired way, while disallowing a narrowing conversion
to 32bit unsigned int on 64bit platforms.
And in the end, we don't want conversions from LUID to
numeric values to happen automatically anyway. But of
course we *do* want automatic promotion from a LuidH
to a PlacementRef...
because this element picking mechanism for tuples
looks like an instance of something generic.
At least I've written almost the same just some days ago
for the revised version of function-closure, where the
task was to replace a stretch of type arguments in
a given tuple type with a stretch of placeholder types
and then to build a modified ctor, which just fills
in the remaining arguments, while default constructing
the placeholder types. And if we look into the GNU
implementation of std::bind, they're using a similar
concept (with the difference that they're building
a functor object, where we use a type converter)
This refactoring also integrates some generally useful
bits into our standard metaprogramming helper collection
quite sure I never really meant to do that, just, at that time,
it seemed logical to treat Placement as yet another smart-ptr.
But in the light of what crucial entity Placement became meanwhile,
I can't imagine a single case where anyone wants to wrap away a
placement as if it was some shrink-wrap
...based on all the clean-up and reorganisation done thus far,
we're now able to rebuild the util::str in a more direct and
sane way, and thus to disentangle the header inclusion problem.
Seemingly I've hit a nasty problem here, because PlacementIndex
should return an Placement&, but this is being fetched
after-the fact from within the iterator.
