I would need some RFC on new tags that I introduced for XKB, from the
point of view of code generators of different languages.
Now I will describe these tags here briefly:
- enumref - it's a reference to already declared enum item e.g.
- if - conditional inclusion of fields, based on expression, it always
is the last field of struct, e.g.
<!-- expression -->
<!-- fields for inclusion -->
<list > ...
- bitcount - counts number of bits set or cleared, e.g.
<bitcount value="1"> <fieldref>namesPresent</fieldref> </bitcount>
- switch - conditional inclusion of fields, in 2 variants:
- case - include exactly one set of fields that matches ( equaltity
comparison ) e.g.:
in this example only y field will be included. This variant is a
bit redundant - it can be replaced by if tag, so I didn't use it ...
- bitcase - include all that matches, in the example above, when
'case' is renamed to 'bitcase', x and y fields would be included in
struct. I used this a lot.
switch is always the last field of struct ( if it is present )
- neg - bit negation, e.g.
- sumof - sumation of elements of list, e.g.
<sumof ref="nLevelsPerType" type="CARD16" />
- replyof - makes copy of reply of given request a field of other
<replyof request="GetMap" name="map" />
I hope that these are all new tags.
