Well, at least one kind of separator character is required (for big
plugins). If it can't be ":", then I don't know what, but there needs
to be something. Maybe "."? If you want to keep it as a valid C
identifier I guess we're pretty much screwed, aside from defining __ to
be interpreted as a sort of heirarchialish separator.
master_amp:vol
master_amp.vol
master_amp__vol
"." is definitely prettiest... is there anything other than "__" we
can
use that's as safe?
I guess
you mean unique in plugin scope? It would also have to have some
restriction on what values it could take, eg. [a-zA-Z][a-zA-Z0-9_]+ some
kind of lowest common denominator between symbols for various languages
would make sense.
Yeah, just unique to the plugin. (Though I guess that would imply the
port could have a URI like pluginuri/porturi but whatever). I think the regexp you mentioned there is fine,
though I think we should
add one separator character other than underscore for various reasons.
":" maybe?
I'd rather not, I'm not sure its legal in Pd (they get bitten by the port
name thing too), and its not in C. Pure selfinterest, but My LADSPA code
is about 50% generated from XML, and I use short names internally for C
symbols. As a side
effect of this, what is now "label" should become
"description" and implicitly be Nice Human Readable Text, not
ugly_c_looking_identifiers (and units definitely need to be seperated).
"Description" is metadata though, so I guess it doesn't belong in the C
file.
The C now only contains the function pointers, a vector of float pointers
and a URI char *. All this stuff belongs outside.
