...no need to enclose empty sections when there are no
attributes or no children. Makes test code way more readable.
TestEventLog_test PASS as far as implemented
...and fix an error (header include order of diagnostics facility)
which prevented the first matcher implementation to work
the after()-match now works as expected
this is the tiny bit of operational functionality needed on top:
whenever we're reconfiguring the predicate, we need to re-trigger
the evaluation (and clear the cached value)
n.b.: I've verified in debugger that the closure is
allocated on the heap and the functors are passed by value
after looking into our various iterator tools,
it seems obvious that our filtering iterator implementation
has almost all of the required behaviour; we only need to
add a hook to rewrite and extend the filtering functor,
which can now nicely done with a lambda closure.
This means all memory management, if necessary, is
pushed into std::function and the automated memory
management for closures provided by the runtime.
...providing the standard implementation of UI-Bus connectivity.
It seems reasonable to place all of the UI-Bus implementation into
a single translation unit
what you see here now is just the tip of the icebearg...
If we follow this route, the Lumiera UI will become way more
elaborate and responsive than average desktop applications
..while we should note at this point that the whole techique
of hijacking std::hash is superfluous now, since the standard libray
does no longer define a static assertion which defeats SFINAE
some tests rely on additional diagnostics code being linked in,
which happens, when lib/format-util.hpp is included prior to
the instantiation of lib::diff::Record rsp. lib::Variant.
The reason why i opended this can of worms was to avoid includion
of this formatting and diagnostics code into such basic headers
as lib/variant.hpp or lib/diff/gen-node.hpp
Now it turns out, that on some platforms the linker will use
a later instantiation of lib::Variant::Buff<GenNode>::operator string
in spite of a complete instantiation of this virtual function
being available already in liblumierasupport.so
But the real reason is that -- with this trickery -- we're violating
the single definition rule, so we get what we deserved.
TODO (Ticket #973): at a later point in development we have to re-assess,
the precise impact of including lib/format-util.hpp into
lib/diff/gen-node.hpp
Right now I expect GenNode to be used pervasively, so I am
reluctant to make that header too heavyweight.
yet another instance of that obnoxious problem that "long"
is just 32bit on i386 platforms. Why the hell does such
a broken type get the preference of convenient notation??
For Lumiera, what we actually need is a GTK-3 compliant libGDL.
Since Mint Rafaela (17.2) has only the rather old version 3.8, we lower
the dependency requirements. Not sure if this causes any problems...
lumiera (0.pre.03-1~rafaela) Lumiera-rafaela; urgency=low
* Rebuild for Mint 17.2 (Rafaela)
* lower requirements on libGDL to 3.8 (a bit outdated, but should do)
* use custom installed gcc-4.9 and libstdc++ 4.9 for building,
since Mint 17.2 has only gcc-4.8 and we need full c++14 compliance
Hint: use add-apt-repository ppa:ubuntu-toolchain-r/test

preliminary workaround for Ticket #972
On Debian/Jessie, we observed the following error
"gtk-lumiera.css:38:19Theming engine 'adwaita' not found"
even though the package gnome-themes-standard *is* installed
This allows at least to bring the UI up, even if loading
our custom theme and stylesheet fails.
this is a bit trickty, since we need to install gcc-4.9 from a PPA.
Mint only provides the libstdc++ 4.8, which is known to break when
compiling in C++14 mode
NOTE: we have the policy to always support current Debian/stable
amd at least one Ubuntu LTS release, unless hard dependency problems prevent that.
Currently, Ubuntu/Trusty is already a bit dated, but the only problematic dependency
could be libboost (1.54 in Trusty, 1.55 in Jessie).
GCC-4.8 can be replaced by GCC-4.9 in Trusty without problems
It is always a bit tricky to find out the precise lower boundary,
so we try to upgrade these requirements as our platform progresses.
For now we have used the level available on Ubuntu/Trusty to set
the lower constraints for most libraries
...this is proposed by debian; lets see how this turns out
We could also add -fstack-protector-strong, but I prefer
to set this in the package definition
This is a development snaphot pre release of Lumiera.
It features codebase maintenance, upgrade to C++14 and GTK-3
and some work towards a Proc-GUI connection (unfinished)
Update README, AUTHORS, LICENSE and similar release docs.
...this will be the third preview release
Lumiera is still in pre-alpha stage, and thus
there are no proper releases, just preview snapshots.
Again this version will be built and packaged
on several supported Linux platforms
This page gives the rationale for the way our diff framework is built.
This reasoning might *reduce* the relevance of any decisions
regarding the implementation data structure and thus lead to
far reaching consequences for the whole architecture.
