after extended analysis, it turned out to be a "placeholder concept"
and introduces an indirection, which can be removed altogether
- simple command invocation happens at gui::model::Tangible
- it is based on the command (definition) ID
- instance management happens automatically and transparently
- the extended case of context-bound commands will be treated later,
and is entirely self-contained
as it turns out, we can always trigger commands right away,
the moment all arguments are known. Thus it is sufficient to
send a single argument binding message, which allows us to
get rid of a lot or ugly complexities (payload visitor).
not quite sure how to get the design straight.
Also a bit concerned because we'll get this much indirections;
the approach to send invocations via the UI-Bus needs to prove its viability
- suppres sending redundant stat mark messages from MockElm
- emit a "reset" state mark when an actual reset happens
- let the PresentationStateManager discard recorded special state
when receiving a "reset" mark for a given element
...and I made the decision *not* to consider any kind of
generic properties for now. YAGNI.
UI coding is notorious spaghetti code.
No point in fighting that, it is just the way it is,
because somewhere you're bound to get concrete, hands-on.
I worked under the erroneous assumption, that Doxygen
will use its internal entity-IDs as the link-IDs when
generating mardown-links. Yes, this seemed logical and
this would be the way I'd implement it....
But seemingly, Doxygen is not so consistent when it
comes to questions of syntax. The same holds true for
markdown, which lacking a coherent definition anyway.
Another problem is that Doxygen's auto-link generation
frequently fails, for reasons not yet clear to me.
Sometimes it seems to be necessary to give it a nudge
by including the \ref command. While I'm not willing
to go into focussed invstigation of Doxygen syntax
right now, at least I've done a search-and-replace
to remove the malformed links I've written the
last days
the initial draft of this concept is in place now, and
the first round of unit tests pass. I've got some understanding
of the purpose of the interactions and involved elements
and I'm confident this design is evolving in a sane way.
Note: extensive documentation is in the TiddlyWiki,
here I've just pasted and reworded some paragraphs from there
and integrated them into the Doxygen docs
