Re: Status of GNUstep

[Doug Simons]

Hmm, a thought occurred to me: Would there be an easy way to determine the 
GNUstep methods (and possibly functions) that are called by an application? The 
idea would be to create a list of methods that are known to be used by one or 
more applications within the community. Even if a method has been implemented 
in GNUstep, it may not actually be in use by anyone in which case it's a bit of 
an unknown whether it actually works correctly. 

Even for the methods that are being used by an app, there's no absolute 
guarantee that they will work correctly in all situations, but we could at 
least be reasonably confident that they are implemented and generally 
functional. We occasionally wonder what the state of development is for a class 
or set of classes that we don't currently use but are considering for use in 
our future development, so having a composite list of usage within other apps 
might come in handy.

Of course, if there's no easy way to extract that information from an app, then 
this is a non-starter, but I would think the linker might be able to generate 
such a list? If so, I'd be happy to generate the list of calls used by eggPlant 
and share that information.

Regards,

Doug
