According to Corinna Vinschen on 12/12/2008 9:13 AM:
"@" for the named value, and "%.val" for the unnamed default?
Backward compatibility would ask for sticking to @ for the default
value. Actually there could be a key and a value called @ so you
have three @ items. :-P
If there is no key or value @, then use @ for the default for
compatibility. If there is either a key or a value named @, then use:
@ - named key
@%val - named value
%val - default value
Something like that, I guess, though it I get headaches imagining that
the default value is not the default value anymore if by chance a @ key
or value exists. It's a pity that we didn't have Christian's patch
right from the start. I'm just glad that this is a seldom border case.
Why not encode "@" as a reserved name like it is already done for "."
and ".." (which appear as "%2E" and "%2E.")? This would provide backward
compatibility and consistency with current conversions:
@ - default value
%40 - named key or value
%40%val - named value if key exists
I will post a patch.
Christian
