No completion returned when source is passed as an unicode object about jedi HOT 11 CLOSED

This works for me (both with current beta as well as with the dev branch).

>>> jedi.Script(u'import json\njson.l', 2, len('json.l'), '').complete()
[<Completion: loads>, <Completion: load>]

I'm on Arch Linux with Python 2.7.3. Can you post your system configuration?

Python 2.7.2+ on Ubuntu 11.10

Ah, and tested against both dev branch and 0.5b3

from jedi.

I can reproduce this also in Python 2.6.7

from jedi.

I think this is because of some fix between Python 2.7.2 and 2.7.3, as test of Emacs Jedi with Python 2.7.3 is passing in Travis CI but the same test with Python 2.7.2 fails in my desktop. Also the same test with Python 2.6 in Travis CI fails.

You're right, I can reproduce this with Python 2.6.8...

I tried to debug this, but don't understand Jedi enough yet to find the bug. All I found was that under Python 2.6, scopes is an empty list while under Python 2.7.3 it contains <Module: /usr/lib/python2.7/json/__init__.py@1-None>.

Could you try the same thing with a str cast?
I'm already doing some strange things with strings, where I'm not entirely sure what's happening:
https://github.com/davidhalter/jedi/blob/master/jedi/_compatibility.py#L81

Could be this change:

• Issue #1548891: The cStringIO.StringIO() constructor now encodes unicode
  arguments with the system default encoding just like the write() method
  does, instead of converting it to a raw buffer. This also fixes handling of
  unicode input in the shlex module (#6988, #1170).

Found in: http://hg.python.org/cpython/file/d46c1973d3c4/Misc/NEWS

Your code in https://github.com/davidhalter/jedi/blob/master/jedi/_compatibility.py#L81

# BytesIO (Python 2.5 has no io module)
try:
    from cStringIO import StringIO as BytesIO
except ImportError:
    from io import BytesIO

Shouldn't this be other way around, like this?:

try:
    from io import BytesIO
except ImportError:
    from cStringIO import StringIO as BytesIO

The current code imports BytesIO.io only in Python3 where cStringIO does not exist.

So, in Python 2.6/2.7:

% python -c 'import jedi; print jedi._compatibility.BytesIO'
<built-in function StringIO>

Python 3.2

% cd jedi
% python3 -c 'import _compatibility; print(_compatibility.BytesIO)'
<class '_io.BytesIO'>

from jedi.

Casting it to str works. I am doing source.encode() before passing it to Jedi.source for Python 2.x

BTW: I'm still struggling with that:

Thanks for the fix! I can confirm that completion works with str and unicode in Python 2.6 and 2.7.
