- remove unnecessary includes
- expunge all remaining usages of boost::format
- able to leave out the expliti string(elm) in output
- drop various operator<<, since we're now picking up
custom string conversions automatically
- delete diagnostics headers, which are now largely superfluous
- use newer helper functions occasionally
I didn't blindly change any usage of <iostream> though;
sometimes, just using the output streams right away
seems adequate.
...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
Note: not fixing all relevant warnings.
Especially, the "-Woverloaded-virtual" of Clang defeats the whole purpose
of generated generic interfaces. For example, our Variant type is instantiated
with a list of types the variant can hold. Through metaprogramming, this
instantiation generates also an embedded Visitor interface, which has
virtual 'handle(TY)' functions for all the types in question
The client now may implement, or even partially implement this Visitor,
to retrieve specific data out of given Variant instance with unknown conent.
To complain that some other virtual overload is now shaddowed is besides the point,
so we might consider to disable this warning altogether
previously this operation was named 'attach', which an be confused
with attching an object to this location. Indeed, the session interface
even offers such an attach function. By renaming the focus moving
operation into QueryFocus::shift(Scope), this ambiguity is resolved
In Clang, static object fields are initialised from top to bottom,
but before any other variables in anoymous namespaces. To the contrary,
GCC evaluates *any* initialisation expression in the translation
unit together from top to bottom. Thus, in the clang generated
code, in two cases the static initialisation could use a not yet
constructed local lib::_Fmt formatter object.
c++11 uses another hashtable implementation.
This uncovered some poorly written tests, which relied on
objects being returned in a specific order. As far as poissible,
we're using generic query functions now to get our test objects.
But these tests still rely on a specifically crafted test index content,
which as such is acceptable IMHO. The only remaining problem is
that we check the order of generated output in some tests, and this
order is still implementation dependent.
to make them stand out more prominently, some entity comments
where started with a line of starts. Unfortunately, doxygen
(and javadoc) only recogise comments which are started exactly
with /**
This caused quite some comments to be ignored by doxygen.
Credits to Hendrik Boom for spotting this problem!
A workaround is to end the line of stars with *//**
lib::Depend<TY> works as drop-in replacement for lib::Singleton<TY>
This changeset removes the convoluted special cases like
SingletonSub and MockInjector.
the buildsystem will now pick up and link
all test cases according to the layer, e.g.
backend tests will automatically be linked
against the backend + library solely.
