Re: [Pyme-help] contants -> constant names? for info

[Igor B. <be...@us...>]

Bernhard,

That's an interesting idea, but I can't think of a python friendly way 
to implement it.

Constants are basically 'integers' which could have conflicting values 
from different components. So, whatever
mechanism is chosen to convert from an integer to a string should be 
component specific.

Another approach would be to make constants into 'objects' and then 
convert them to integers when they
are passed to gpgme and have __str__() method which prints their name 
instead of their value but I think
it's overkill for just an easier 'verbose' capability.

Let me know what implementation exactly you have in mind.

Thanks,
Igor
