CL-format is a Python implementation of the format function in Common Lisp.

The function itself just depends on builtins, the str module and the itertools module.

As the format in Common Lisp used a complex rules (a powerful DSL, acctually) to format a sting, it's not that easy to reimplement a Python fork elegantly for me, so any help will be greatly appreciated.

NOTICE: Only tested in CPython 3.4.1, I'm sorry but clformar cannot works in PyPy3 now. I'll fix this after the function finally works.

from clformat import clformat

or

from clformat import *

and try it:

clformat(None, '~{~A~}!', ['Hello', ' ', 'world'])
