...and learned a lot about the new type_traits on the way.
As it seems, it is not possible to get a clean error message
when passing an "object" with no custom string conversion;
instead, some overload for an rvalue-ostream kicks in.
probably I'll go for shoing a type string in these cases
now we use boost::format through our own front-end util::_Fmt
solely, which both helps to reduce compilation time and code size,
and gives us a direct string conversion, which automatically
uses any custom operator string() available on arguments.
While desirable as such, I did this conversion now, since
it allows us to get rid of boost::str, which in turn helps
to drill down any remaning uses of our own util::str
this was introduced into namespace mobject and spread from there.
Since the habit is to use more specific typedefs like PClip,
it is preferrable to spell out the full namespace
Ouch!
Why does C++ lack the most basic everyday stuff?
It needn't be performant. It needn't support some fancy
higher order container. Just join the f***ing strings.
use Bosst?? -- OMG!! pulls in half the metra programming library
and tries to work on any concievable range like object. Just
somehow our Lumiera Forward Iterators aren't "range-like" enough
for boost's taste.
Thus let's code up that fucking for-loop ourselves, once and forever.
Clang doesn't allow to declare a private nested class as friend.
This is unfortunate, but likely correct to the letter of the standard.
As a workaround, now we're creating the instances within a static
function of DependencyFactory -- in the end this improves readability
A second issue fixed with this changeset is the scope of the
marker function. Clang is right, this isn't ADL, thus an inline
friend definition is simply not visible outside the class.
lib::Depend<TY> works as drop-in replacement for lib::Singleton<TY>
This changeset removes the convoluted special cases like
SingletonSub and MockInjector.
these simple utils (length of typelist, maximum size
containment test) are mostly not used in conjunction
with the more elaborate typelist manipulatino utils.
Moreover, we lacked a dedicated unit test
