gnu readline – python

This is the very start of our cryptanal program frontend

#!/usr/bin/env python

import readline

"""The shell class is the front end for cryptanal"""

class shell:
  def __init__(self, filename=None):
WWW         WW eEeEeEeE LL        CCCCC    OOOO    MMMM    MMMM  eEeEeEeE
 WW         W  EE       LL       Cc      OOO  OOO  MM MM  M  MM  EE
  WW       WW  EeEeE    LL      CC       OO    OO  MM  MMM   MM  EeEeE
  WWw WW  WW   EE       LL       Cc      OOO  OOO  MM        MM  EE
   WWW  WWW    eEeEeEeE LlLlLlL   CCCCC    OOOO    MM        MM  eEeEeEeE

                             TO CRYPTO-SHELL
  (Useful for deciphering what little Susie is writing to little Billy)

    self.filename = filename
    self.crypto = None
    #if self.filename != None:
      #self.crypto = freqcount.subCryptAnal(self.filename)

    #setup the tab completion information here
    self.commands = ["help", "printfreq"]
    readline.parse_and_bind("tab: complete")

  #completer funtion for tab complete
  def completer(self, word, index):
    matches =
      return matches[index] + " "
    except IndexError:

  #this is the main event loop
  def mainloop(self):
    while 1:
      command=raw_input('> ').lstrip()
      if command.lower().startswith('help'):[4:].lstrip())
        print "Error: command not recognized"

  def help(self, args):
    print "HELP"

if __name__ == '__main__':
