Hmmm. Up to now, we had two structures (three for shapes) :
ObjectType and SheetObject. The former describes the object type ; the
second describes some decoration and that user_data field only two object
use, in integer form.
Now, we would have to have three structures (four) : ObjectType,
SheetObject, and the <object> (or <sheetobj>, whatever) node.
Hmmm. What I've begun coding is to have a ${pkgdatadir}/sheets (with
perhaps a way to specify the order of sheets in diarc), and sheet files a
bit more featureful :
<?xml version="1.0"?> <!-- -*- xml-mode -*- -->
<sheet xmlns="http://www.crans.ens-cachan.fr/~chepelov/dia-sheet-ns">
<name>Test</name>
<description xml:lang="fr">Une feuille de test</description>
<description>A test sheet</description>
<contents>
<object name="UML - Class" intdata="1">
<description>a template uml class</description>
<icon>foo.xpm</icon>
</object>
<object name="Network - Antenna">
<description>Antenna</description>
</object>
<shape name="Circuit - NPN Transistor" />
</contents>
</sheet>
The object and shape objects are to be identically processed, save the
optional intdata and chardata properties (for objects).
Each object or shape node is converted into a SheetObj structure and
registered in the relevant sheet.
The description and icon elements override whatever could have previously
be given (in ObjectType or in ShapeInfo).
index.sheet files are deprecated ; All shapes available are loaded, their
ObjectType registered ; I'll just need a routine to retrieve information
from the name_to_info hash (not really an issue, is it ?).
I have something working right now, but limited to binary objects. I think
I'll have shapes as well later this evening.
