...which uncovers further deeply nested problems,
especially when referring to non-copyable types.
Thus need to construct a common type that can be used
both to refer to the source elements and the expanded elements,
and use this common type as result type and also attempt to
produce better diagnostic messages on type mismatch....
...in an attempt to clarify why numerous cross links are not generated.
In the end, this attempt was not very successful, yet I could find some breadcrumbs...
- file comments generally seem to have a problem with auto link generation;
only fully qualified names seem to work reliably
- cross links to entities within a namespace do not work,
if the corresponding namespace is not documented in Doxygen
- documentation for entities within anonymous namespaces
must be explicitly enabled. Of course this makes only sense
for detailed documentation (but we do generate detailed
documentation here, including implementation notes)
- and the notorious problem: each file needs a valid @file comment
- the hierarchy of Markdown headings must be consistent within each
documentation section. This entails also to individual documented
entities. Basically, there must be a level-one heading (prefix "#"),
otherwise all headings will just disappear...
- sometimes the doc/devel/doxygen-warnings.txt gives further clues
- an extension to our custom toString and typeString helpers.
- currently just for shared_ptr and unique_ptr
- might add further overloads for other smart-ptr types
recently, I've introduced this ability in our toString template.
as it turned out, the bool type was not selected by our
boost::format frontend for special treatment, thus showing
just the fallback «bool»
- replace remaining usages of typeid(T).name()
- add another type simplification to handle the STL map allocator
- clean-up usage in lib/format-string
- complete the unit tests
- fix some more bugs
over time, we got quite a jungle with all those
shome-me-the-type-of helper functions.
Reduced and unified all those into
- typeString : a human readable, slightly simplified full type
- typeSymbol : a single word identifier, extracted lexically from the type
note: this changeset causes a lot of tests to break,
since we're using unmangeled type-IDs pretty much everywhere now.
Beore fixing those, I'll have to implement a better simplification
scheme for the "human readable" type names....
use a shortened display, showing only the last 4 bytes for diagnostics
since we're typically only interested in spotting "same" and "different",
while the full memory address is irrelevant
- simple function to pick up the mangled type
- pretty-printing is implemented in format-obj.cpp
- also move the demangleCxx()-Function to that location,
it starts to be used for real, outside the test framework
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
our front-end for boost::format, the class lib::_Fmt
was lacking an reliable specialisation for long and ulong.
This is due to the notorious problem of these types being
of platform dependant size. As a fix, we're speclialising
explicitly for int16_t, int32_t and int64_t and avoid the
common names 'short', 'int' and 'long' alltogether.
And especially for non-64bit-platform (NONPORTABLE)
we add an explicit specialisation for long
some basic types are passed on directly;
for those, we use explicit specialisations
in the implementation file, and a traits template
to mark those cases in the header.
custom types with custom string conversion will
be converted to string; everything else
just becomes a type id
