obviously, we get a trivial case, when the path is explicit,
and we need a tricky full blown resolution with backtracking
when forced to interpolate wildcards to cover a given UICoord
spec against the actual UI topology.
Do we need it?
* actually not right now
* but already a complete implementation of the ViewSpec concept
requires such a resolution
...to limit them to the UI-Coordinates themselves,
while declining the possibility to mutate the target environment
through the PathResolver. Better handle changes within the
target environment by dedicated API calls on the target elements,
instead of creating some kind of "universal structure"
..this collection of ideas, terms and conclusions has been shaped
since some time within the TiddlyWiki. Since I've now started even
some supporting implementation regarding these concepts, its time
to publish them in the design documentation section of the Website
After completing the self-contained UICoord data elements,
the next thing to consider might be how to resolve UI coordinates
against an actual window topology. We need to define a suitable
command-and-query interface in order to build and verify this
intricate resolution process separated from the actual UI code.
exploring the idea of a configuration DSL.
As a first step, this could be a simple internal DSL,
implemented as a bunch of static functor objects, which are internally bound
and thus implemented by the ViewLocator within InteractionDirector
...we have to face the problem that we need some generic strategy
for access to component views, which possibly will become customisable.
And the allowed patterns of access are quite different for the various
kind of view we know....
responsible for access and allocation of component views.
Internally wired to the PanelLocator within the global WindowLocator
This setup settles those nasty qeustions of crosswise top-level access
this starts work on a new UI global topic (#1004)
- coin a new term: "view component"
- distinction between veiw component and Panel
- consider how to locate view components
- WindowList becomes WindowLocator
actually I do not know much regarding the actual situation when,
within the Builder run, we're able to detect a change and generate
a diff description. However, as a first step, I'll pick IterSrouce
as a base interface and use a "generation context", which is to be
passed by shared-ptr
the (trivial) implementation turned out to be correct as written,
but it was (again) damn challenging to get the mulithreaded chaotic
test fixture and especially the lambda captures to work correct.
