split string saving screened spaces

[Sergey]

Which module to use to do such thing:

"-a -b -c '1 2 3'" -> ["-a", "-b", "-c", "'1 2 3'"]

(i have string, need to pass it to getopt)

[color=blue][color=green][color=darkred]
>>> import shlex
>>> shlex.split("-a -b -c '1 2 3'")[/color][/color][/color]
['-a', '-b', '-c', '1 2 3']

seems like CSV except that the seperator is space. You may check to see
if the CSV module can take space as delimiter.

Pyparsing has built-in quoted string support.


from pyparsing import OneOrMore,Word, alphanums,quote dString

item = Word('-',alphanums) | quotedString | Word(alphanums)
items = OneOrMore(item)

print items.parseStri ng( "-a -b -c '1 2 3' -d 5 -e zork2000" )

gives:
['-a', '-b', '-c', "'1 2 3'", '-d', '5', '-e', 'zork2000']
