[wingide-users] Autocomplete python more liberally

[Jonathan Mozes]

What about implementing ipython's ipy_greedycompleter?

This is less 'relaxed' than a word list driven completer, but is more
powerful than the current (code, not shell) completer.

A primitive word list driven completer is possible using the scripting
API but it's not possible to integrate that well with the regular
auto-completer.

I've appended below a sample script that uses the argument entry
facility at bottom of the editor window to provide simple word-list
driven completion based on the current file contents.

If you put this into the 'scripts' folder in your user settings
directory (which varies in location and is listed 5th in Wing's
About box) and do Reload All Scripts from the Edit menu, then
you can bind a key binding to the command word-list-completion.
It shows a completer once you start typing.

This is just a toy, really, but I thought it may be useful and/or
interesting.

# Example of using arginfo to provide word list driven autocompletion
# via a script

import string
import wingapi

def word_list_completion(word):
   ed = wingapi.gApplication.GetActiveEditor()
   start, end = ed.GetSelection()
   doc = wingapi.gApplication.GetActiveDocument()
   doc.DeleteChars(start, end-1)
   doc.InsertChars(start, word)
   ed.SetSelection(start + len(word), start + len(word))

def _ArgInfo_word_list_completion():
   from wingutils import datatype
   from guiutils import formbuilder
   from command import commandmgr

   doc = wingapi.gApplication.GetActiveDocument()
   txt = doc.GetText()

   class CWordMap:
     def __init__(self, chars):
       self.chars = set(chars)
     def __getitem__(self, char):
       if unichr(char) in self.chars:
         return char
       else:
         return u' '

   trans = CWordMap(unicode(string.letters + string.digits + '_'))
   txt = txt.translate(trans)

   words = txt.split()
   choices = set()
   for word in words:
     choices.add(word)

   arginfo = {
     'word': commandmgr.CArgInfo(
       "Word", datatype.CType(''),
       formbuilder.CSmallTextGui(choices=list(choices)),
       "Word:", 'internal'
     )
   }
   return arginfo

word_list_completion.arginfo = _ArgInfo_word_list_completion
