Fixes completions err with jedi

[Congee]

a = (x for x in range(10))
Then, as you type a(, jedi complains as following:

In [1]: a=(x for x in range(10)) In [2]: a(Exception in thread Thread-4: Traceback (most recent call last): File "/usr/local/lib/python3.4/site-packages/jedi/cache.py", line 137, in wrap return getattr(self, name) AttributeError: 'LazyName' object has no attribute '_parent' ~ During handling of the above exception, another exception occurred:r] Execute > Traceback (most recent call last): File "/usr/local/lib/python3.4/site-packages/jedi/evaluate/compiled/__init__.p return evaluator.compiled_cache[key][0] KeyError: (4511290496, 4510349128, 4510349128) During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/local/Cellar/python3/3.4.2_1/Frameworks/Python.framework/Versions/3 self.run() File "/usr/local/lib/python3.4/site-packages/prompt_toolkit/eventloop/base.py" callback() File "/usr/local/lib/python3.4/site-packages/prompt_toolkit/__init__.py", line completions = list(line.completer.get_completions(document)) File "/usr/local/lib/python3.4/site-packages/prompt_toolkit/contrib/python_inp completions = script.completions() File "/usr/local/lib/python3.4/site-packages/jedi/api/__init__.py", line 161, for call_sig in self.call_signatures(): File "/usr/local/lib/python3.4/site-packages/jedi/api/__init__.py", line 574, self._pos, user_stmt) File "/usr/local/lib/python3.4/site-packages/jedi/cache.py", line 90, in wrapp value = optional_callable() File "/usr/local/lib/python3.4/site-packages/jedi/api/__init__.py", line 572, _callable = lambda: self._evaluator.eval_call(stmt_el) File "/usr/local/lib/python3.4/site-packages/jedi/evaluate/__init__.py", line return self.eval_call_path(path, par, s.start_pos) File "/usr/local/lib/python3.4/site-packages/jedi/evaluate/__init__.py", line search_global=True) File "/usr/local/lib/python3.4/site-packages/jedi/evaluate/__init__.py", line return f.find(scopes, resolve_decorator, search_global) File "/usr/local/lib/python3.4/site-packages/jedi/debug.py", line 51, in wrapp result = func(*args, **kwargs) File "/usr/local/lib/python3.4/site-packages/jedi/evaluate/finder.py", line 46 names = self.filter_name(scopes) File "/usr/local/lib/python3.4/site-packages/jedi/evaluate/finder.py", line 89 scope = name.parent.parent File "/usr/local/lib/python3.4/site-packages/jedi/cache.py", line 139, in wrap result = func(self) File "/usr/local/lib/python3.4/site-packages/jedi/api/interpreter.py", line 97 return compiled.create(self._evaluator, self._value, module, module) File "/usr/local/lib/python3.4/site-packages/jedi/evaluate/compiled/__init__.p result = func(evaluator, obj, parent, module) File "/usr/local/lib/python3.4/site-packages/jedi/evaluate/compiled/__init__.p faked = fake.get_faked(module and module.obj, obj) File "/usr/local/lib/python3.4/site-packages/jedi/evaluate/compiled/fake.py", result = _faked(module, obj, name) File "/usr/local/lib/python3.4/site-packages/jedi/evaluate/compiled/fake.py", cls = search_scope(faked_mod, obj.__objclass__.__name__) AttributeError: 'generator' object has no attribute '__objclass__' 

There should be one way to handle various syntax errors which jedi complains at.

Somehow, I agree that we should catch all errors, but on the other hand, I prefer to keep track of all the bugs in Jedi, in order to report them and get to fix it. (Jedi is the best autocompletion library for Python available but it still contains a lot of bugs -- and we should get them fixed.)

What I will probably do is add a catch-all for unknown exceptions, but print the traceback to the terminal without crashing. Then, if reported and when a Jedi issue has been created I'll silently catch that exception.

[Congee]

I think so. :)

Opening this again, that I don't forget about this.

Closing this. We have a new version of Jedi as well.
