I am trying to implement an arbitrary autocomplete on windows for a command-line user interface I am writing. Inspired by the first answer to that question, I tried to just run the script written there, before realizing that I was on Windows and needed to use pyreadline instead of readline. After some trials I ended up with the script below, which is basically a copy-paste, but with pyreader initialization:
from pyreadline import Readline
readline = Readline()
class MyCompleter(object): # Custom completer
def __init__(self, options):
self.options = sorted(options)
def complete(self, text, state):
if state == 0: # on first trigger, build possible matches
if text: # cache matches (entries that start with entered text)
self.matches = [s for s in self.options
if s and s.startswith(text)]
else: # no text entered, all matches possible
self.matches = self.options[:]
# return match indexed by state
try:
return self.matches[state]
except IndexError:
return None
completer = MyCompleter(["hello", "hi", "how are you", "goodbye", "great"])
readline.set_completer(completer.complete)
readline.parse_and_bind('tab: complete')
input = raw_input("Input: ")
print "You entered", input
The problem is however when I try to run that script, <TAB> does not lead to autocomplete.
How do I get <TAB> to perform the autocompletion behavior?
Initially I though I messed up the completer setting and binding initialization that would be different for pyreadeline compared to readline, but from module code and examples in pyreadline docs it looks they are identical.
I am trying to execute it on 2.7 Anaconda Python distribution in Windows 10, if this is of any use.
