Feature request: end with python data about pyp HOT 4 OPEN

wow, that's pretty cool. would you mind adding it to the main code body and 
test it, and we'll roll it into our next dev release. Would it be possible to 
add something for "p" as well? 

thanks!

Sorry I don't use SVN.

Add these imports:
import copy_reg
try:
    import cPickle as pickle
except ImportError:
    import pickle


Add this before the Pyp class:

copy_reg.pickle(PypStr, lambda self: (str, (str(self),)))
copy_reg.pickle(PowerPipeList, lambda self: (list, (list(self),)))
copy_reg.pickle(PypList, lambda self: (list, (list(self),)))

Add this method to PowerPipeList:

    def pickle(self):
        """Usage with bash redirections:
        $ python -i <(informative_command | pyp "w[0].isdigit() | pp.sort() | pp.pickle()")
        >>> pp
        ['1 a', '2 b', '3 c']

        Usage with files:
        $ informative_command | pyp "w[0].isdigit() | pp.sort() | pp.pickle()" > my_data.py
        $ python -i my_data.py
        >>> pp
        ['1 a', '2 b', '3 c']

        pp.pickle() must be the last command in the chain.
        """
        return "import cPickle; pp = cPickle.loads(%r)" % (pickle.dumps(self),)

What do you want p.pickle() to do? It would pickle each line seperately but 
then there is no way to manipulate that string using pyp nor is there a way to 
load it into python.

Actually would be better if it generated "import pickle" if the cPickle import 
failed, although this is quite rare.

pretty cool. we'll try to add this to the next dev version. You're right, using 
pp is best.
