The rlcompleter Module

(Optional, Unix only) The rlcompleter module provides word completion for the readline module.

To enable word completion, just import this module. By default, the completion function is bound to the Esc key. Press Esc twice to finish the current word. To change the key, you can use something like:

import readline
readline.parse_and_bind("tab: complete")

The script in Example 14-10 shows how to use the completion functions from within a program.

File: rlcompleter-example-1.py

import rlcompleter
import sys

completer = rlcompleter.Completer()

for phrase in "co", "sys.p", "is":
 print phrase, "=>",
 # emulate readline completion handler
 try:
 for index in xrange(sys.maxint):
 term = completer.complete(phrase, index)
 if term is None:
 break
 print term,
 except:
 pass
 print

co => continue compile complex coerce completer
sys.p => sys.path sys.platform sys.prefix
is => is isinstance issubclass
