I have used multiple run-time language support in an embedded system before.
That system used an id to lookup a string in a language file, basically the
same principle as Daniel is proposing.
I see no issues using this system for RockBox. The only thing is that the
id needs to be very descriptive - preferably implement some naming
convention for the id constants. I think this has been discussed before.
ie. LANG_ID_NNN where NNN is as close to the actual string as possible, eg.
LANG_ID_HELLO_WORLD. The embedded system I had the pleasure of working with
before just used magic numbers which was a complete and utter nightmare.
I beleive we should use an id to lookup the string, rather than string
matching - we just don't have that much processing time to waste. As long
as an id convention is policed :-), then this is a far better solution for
Question: How will this system handle printf format strings? - eg. we can't
put %d in the id macro name.
