[mod_python] Feature Request: Additions to mod_python.util

Yo Sean,
I just wrote the encode/decode functions recently and
posted them on by blog:
http://2centspoorer.blogspot.com/2006/01/urlencoderdecoder-for-python.html

regards,
Courtney


anyway here it is...


_keys = [
  "$", "&", "+", ",", "/", ":", ";", "=", "?", "@", "
", '"',
  "<", ">", "#", "%", "{", "}", "|", "\\", "^", "~",
"[", "]", "`"]

_vals = [
  '%24', '%26', '%2B', '%2C', '%2F', '%3A', '%3B',
'%3D', '%3F',
  '%40', '%20', '%22', '%3C', '%3E', '%23', '%25',
'%7B', '%7D',
  '%7C', '%5C', '%5E', '%7E', '%5B', '%5D', '%60']

def encode(str=""): 
  """ URL Encodes a string with out side effects
  """
  return "".join([_swap(x) for x in str])

def decode(str=""):
  """ Takes a URL encoded string and decodes it with
out side effects
  """
  if not str: return None
  for v in _vals:
    if v in str: str = str.replace(v,
_keys[_vals.index(v)])
  return str 

def _swap(x):
  """ Helper function for encode. 
  """
  if x in _keys: return _vals[_keys.index(x)]
  return x

### units ###
if __name__ == "__main__":
  assert("".join(_keys) ==
decode(encode("".join(_keys))))
  assert("".join(_vals) ==
encode(decode("".join(_vals))))
  print "passed all unit tests."
