Lessons learned from field prototypes and WW doc analysis
Needed:
a) Field need be considered for line break.
b) Fields need traversable.
c) Fields need to be nestable
Optional:
d) Fields must be able to cross paragraph boundaries.
when we do something with our fields we should not stop half-way.
Fields should be able to include everything that a document body can
contain. They should be able to start inside of paragraphs and end
inside of paragraph. How else should we be able to implement fields that
resolve file links or expand AutoText blocks?
Additionally this would prevent <field-start/> and <field-end/> marks in ODF
:-) However I way result in slightly different layouts.
The way these new fields will be specified in the file format does not
influence the implementation. Although I like the field-start/field-end
approach. ODF already uses a similar approach for bookmarks. Why
shouldn't that work for fields?
At the end I would prefer to reuse the existing field mechanism and simply
enhance the layout code such that a) fields considered for line break and c)
field texts can also contains field wildcards. This again has to be considered
by the layout code.
There's no need for the layout to change. Field content is nothing else
than normal content.
Regarding b) I would like to introduce a special field edit mode”, similar to
the XForm edit mode.
The idea:
We add an additional SwNode array to a SwDoc or reuse one of the existing
areas. We introduce a new special “field wildcards” which references an SwNode.
Sorry, that sounds like an ugly hack to me.
We enhance the layout such that these new field codes are recognized and that
the text is loaded from the SwNode.
By having the text of the fields stored in SwNodes we can place a cursor to it
:-)
Having fields as start/end marks in the document allows cursor
travelling without implementing one additional line of code in the
layout or in cursor travelling.
Regards,
Oliver
