- reorganise the navigation tab structure
- place all further index lists into a common "Index" tab
- include a list of concepts
- remove the various "member" sub-tabs, these are not helpful
- the "modules" tab is now called "topics" (since C++ has now Modules!)
- generally re-sync DoxygenLayout.xml with a current pristine template
- comb though the Doxygen Warnings and fix a lot of small problems
* Lumiera source code always was copyrighted by individual contributors
* there is no entity "Lumiera.org" which holds any copyrights
* Lumiera source code is provided under the GPL Version 2+
== Explanations ==
Lumiera as a whole is distributed under Copyleft, GNU General Public License Version 2 or above.
For this to become legally effective, the ''File COPYING in the root directory is sufficient.''
The licensing header in each file is not strictly necessary, yet considered good practice;
attaching a licence notice increases the likeliness that this information is retained
in case someone extracts individual code files. However, it is not by the presence of some
text, that legally binding licensing terms become effective; rather the fact matters that a
given piece of code was provably copyrighted and published under a license. Even reformatting
the code, renaming some variables or deleting parts of the code will not alter this legal
situation, but rather creates a derivative work, which is likewise covered by the GPL!
The most relevant information in the file header is the notice regarding the
time of the first individual copyright claim. By virtue of this initial copyright,
the first author is entitled to choose the terms of licensing. All further
modifications are permitted and covered by the License. The specific wording
or format of the copyright header is not legally relevant, as long as the
intention to publish under the GPL remains clear. The extended wording was
based on a recommendation by the FSF. It can be shortened, because the full terms
of the license are provided alongside the distribution, in the file COPYING.
...for the operation on a PlantingHandle, which allows
to implant a sub type instance into the opaque buffer.
* "create" should be used for a constructor invocation
* "emplace" takes an existing object and move-constructs
After this long break during the "Covid Year 2020",
I pick this clean-up task as a means to fresh up my knowledge about the code base
The point to note is, when looking at all the existing diff bindings,
seemingly there is a lot of redundancy on some technical details,
which do not cary much meaining or relevance at the usage site:
- the most prominent case is binding to a collection of DiffMutables hold by smart-ptr
- all these objects expose an object identity (getID() function), which can be used as »Matcher«
- and all these objects can just delegate to the child's buildMutator() function
for entering a recursive mutation.
basically the solution was a bit too naive and assumed everything is similar to a vector.
It is not, and this leads to some insidious problems with std::map, which hereby
are resolved by introducing ContainerTraits
All of the existing "simple" tests for the »Diff Framework« are way to much low-level;
they might indeed be elementary, but not introductory and simple to grasp.
We need a very simplistic example to show off the idea of mutation by diff,
and this simple example can then be used to build further usage test cases.
My actual goal for #1206 to have such a very basic usage demonstration and then
to attach a listener to this setup, and verify it is actually triggered.
PS: the name "GenNodeBasic_test" is somewhat pathetic, this test covers a lot
of ground and is anything but "basic". GenNode in fact became a widely used
fundamental data structure within Lumiera, and -- admittedly -- the existing
implementation might be somewhat simplistic, while the whole concept as such
is demanding, and we should accept that as the state of affairs
