r989: Completion fails in python script buffer

[Richard Stanton]

With r989 under Windows, if I open a python script file (with ipython set as my default python shell), type some text, e.g., "ex", then press ESC-TAB to complete, Emacs waits for several seconds, then the cursor moves to the next tab position, I get the message "Completion function py-completion-at-point uses a deprecated calling convention" in the Minibuffer, and no completion activity occurs (not even a message telling me there are no completions).

This may well be related to #1004329.

[Richard Stanton (a-stanton)]

With r991, the cursor stays where it is, but now after typing "ex", ESC-TAB, I get the message

Can't find completion for "ex"

In a regular ipython shell (not running under Emacs), I am offered four choices of completion:

In [1]: ex
except exec execfile exit

thats the result from test here also - ie a buffer *Python Completions* is opened displaying it

what tells

C-h v completion-at-point-functions RET

?

Thanks

[Richard Stanton (a-stanton)]

completion-at-point-functions is a variable defined in `minibuffer.el'.
Its value is (ipython-complete t)
Local in buffer run.py; global value is nil

does it still happen after re-compile and reload?

Does shebang not tell other than ipython?

thanks,

Andreas

[Richard Stanton (a-stanton)]

I shut down Emacs and restarted - same result.

There's no shebang line in my script file. Instead, init.el contains the line

(setq py-shell-name "c:/python27/Scripts/ipython.bat")

okay, seeing some bug if no shebang is given, thanks.

bug seems done

[Richard Stanton (a-stanton)]

With r1012 under Windows, when I press ESC-TAB to complete "ex", I just get a message telling me (erroneously)

Can't find completion for "ex"

[Richard Stanton (a-stanton)]

Two more pieces of information:

1) It fails on my Mac too.

2) When I press ESC-TAB, event though it reports not finding any completions, the *IPython-Complete* buffer has the following contents:

-----------

In [2]:
In [3]:
In [4]: except;exec;execfile;exit

In [5]:
-----------

ah, thanks, that's good

as you see, it offers you choices to complete, it can't now what to select. I.e. completion is only performed, if
singular.

Switching into the *IPython-Complete* buffer and pointing to it, should insert the completion.
If not, it's a bug

[Richard Stanton (a-stanton)]

Oddly, it now works on my Mac! I get a *Python Completions* buffer popping
up with four choices, and I can click on whichever one I want. This is the
behavior I want, but it's not what happens on my Windows machine. There,
the first time I press ESC-TAB, I get a message telling me it's unable to
complete "ex". If I then press ESC-TAB again, I get the same (correct)
behavior as on my Mac.
