Hi,
I promised more details about a new option type "enum" in the
configuration scheme. Basically it is jut a special case of an integer
that _requires_ a "valid" attribute in the driver's XML document in
order to guarantee enumerability. Furthermore individual values _can_
(but don't need to) be described inside the description elements. This
means:
- the description element is no longer empty it can contain enum elements
- enum value descriptions are internationalized
- enum value descriptions are only documentation
- in the configuration files integer values are stored for enum options
A realistic example:
In a driver's XML document:
...
<option name="vsync" type="enum" valid="0:3" default="3">
<description lang="en" text="Synchronization with vertical blanks">
<enum value="0" text="Never, FPS rulez ;-)"/>
<enum value="1" text="Application preference, default off"/>
<enum value="2" text="Application preference, default on"/>
<enum value="3" text="Application preference, always at least 1"/>
</description>
<description lang="de" text="Synchronisation mit vertikalen
Kathodenstrahlrückläufen">
<enum value="0" text="Niemals; immer die maximale Framerate"/>
...
</description>
</option>
...
In a configuration file:
...
<option name="vsync" value="2"/>
...
I believe this solution is very flexible and keeps the implementation
complexity small as the drivers don't need to parse symbolic values from
configuration files. Comments?
Regards,
Felix
