[wingide-users] Autocomplete python more liberally

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

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

# Example of using arginfo to provide word list driven autocompletion

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

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

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

   arginfo = {
     'word': commandmgr.CArgInfo(
       "Word", datatype.CType(''),
       "Word:", 'internal'
   return arginfo

word_list_completion.arginfo = _ArgInfo_word_list_completion
