The problems I've run into in comprehending the Theme layer: o The "library" files are too big and contain too many ideas. A single river of templates makes it hard for me to grasp their relationships. I'd like to see them broken down into a larger set of smaller, more focused files, much as the Java code is.
Not necessarily, however, by the type of page produced. That would
entail a lot of duplication of the implementations of cross-cutting
concerns and common requirements.
o Documentation, documentation, documentation. I'd like to go
through the templates and work over the comments on each one, but I
don't yet feel that I understand them well enough to do that.
o No data dictionary. There is a rich set of "hints" that the Aspect
chain can use to tell the Theme engine what its intent is
w.r.t. some element, but I haven't found any comprehensive list of
them. To know how to proceed, the method seems to be "read the
entire library and every Theme you use, until you find something
that seems to fit."
o Too much copying. Some of the templates might be further broken
down into "subroutines", so there is less copying of a large template
just to make a small change. This will require compiling and
analyzing a lot of input from the community about what UI features
they usually want to change, and how. (This might also allow us to
group many of the callouts for those "hot spots" into a single file
without a lot of distractions, if the common customizations are
conceptually closely enough related.)
