The category tag was rarely used and thus not very useful. This adds
categorization to most modules (the rest will follow) and uses the
\DeclareCategory tag we use in layouts rather than the extra syntax
we used in modules. Categories are now added to the po files and
translated.
Note that this is work in progress: the current categories are still
subject to change.
The ultimate goal of this is to sort the modules in the GUI by category
as we do with layouts, examples and templates (and add a filter to search
for specific modules)
As it is now (with the many modules we accumulated), the module selector
is not really usable anymore. If you don't happen to know how exactly a
module is named, selecting a module is really a PITA.
This uses the InsetArgument interface to provide access to a document
part hitherto inaccessible by LyX: the part between \begin and the first
\item in a list (where lengths and counters can be redefined, for
instance).
Fixes: #11098
File format change, layout format change
Now layout files and modules can extend the cite engines or completely
overwrite them, and modify the cite formats.
Any CiteEngine definition in a layout/module will completely overwrite
those by cite engine files.
AddToCiteEngine will extend them (add if they do not exist yet).
Any CiteFormat definition in a layout will be preferred to those in cite
engines. CiteFormat definitions that are not touched by the former are
still active, though (so, as opposed to CiteEngine, a CiteFormat does
not completely overwrite those by the engine files).
Layout format change.
The current spelling is not strictly wrong, but flagged as unusual or
historical by some authorities. It is also found fault with many
spell checkers. Thus we decided to move to the more standard "-ible"
form once and for all.
See #10678 for discussion
This last part updates the layout format and changes collapsable color.
This will all also all be backported to 2.3.x, for the sake of backwards
compatibility (cherry-picking).
Remove the trimming operation on LabelString, LabelStringAppendix,
EndLabelString and LabelCounter. This trimming meant that quotes
strings were not preserved, which is wrong.
To preserve layouts, the Layout format has been updated to 64, so that
layout2layout can remove extra spaces on existing strings, which
ensures that behavior is unchanged for old layouts (courtesy of rgheck).
It is now possible to re-add spaces in label strings where it makes
sense.
Fixes bug #10723.
