Hi,
I am more or less new to TW and I may not have a good overview or a good
understanding, but there is something I have been wondering about and
maybe your answers will help me to deepen my understanding of TW.
From what I can tell widgets are a way to enhance WikiText with the
goal of displaying content that it would not normally be able to display
by default. A good example would be the list widget. Many of these
widgets also provide a little bit of functionality that would otherwise
not exist. Examples here are the widgets that provide the typical
HTML-Form elements like a button, a checkbox/radiobox, textareas, etc..
But I notice that an increasing number of widgets just exist to do a
purely functional task which mostly does not involve rendering things or
doing something with the child elements of that widget. And most of
these are not designed to play exceptionally well together.
For example the checkbox widget works on tags, the edit widget on
fields. To use them for something else, you usually have to do something
extra, like transcluding the field or checking for tags.
Also widgets make use of different concepts, the $mangletags widget from
Matabele follows his stacking mechanism where high-level functionality
is archieved by wrapping AROUND a source element, which propagates the
target UP the stack. Other widgets like the core set widgets propagate
variables DOWN the stack and are used to provide the necessary
parameters for the high-level functionality INSIDE the stack. Some use
messages as parameters, others solely rely on their attributes as input.
Now my question: Is there a guideline or a core concept which is meant
to ensure that widgets work well together ? Are widgets even supposed to
work together ? (How will they do this in the future ?) And finally:
what was the idea/purpose behind widgets when TW was created ?
I would love a short explanation of the more or less theoretical
background and concepts of this part of TW.
Thanks
/Andreas
