jedi's Issues

Follow imports?

Currently completion object for json.JSONEncoder has "Import" as scope, not "Class".

In [7]:
comp
Out [7]:
<Completion: JSONEncoder>

In [8]:
parent = comp.name.parent()
parent
Out [8]:
<Import: from .encoder import JSONEncoder @109>

It would be nice if jedi "follows" imports so that I can get docstring for imported objects such as JSONEncoder.

Request: add jedi installation document.

As the title(subject) said.

Add Django project root to PYTHONPATH

...so that imports relative to the project root work.

You can detect a Django root folder by looking for the manage.py module.

docstrings in vim completion

Is this not implemented yet or does it have to be an issue with my setup? values returned by functions.complete() always have empty help attributes.

Completion for `threading.` fails in dev head

Completing

import threading
threading.

fails with AttributeError("'Flow' object has no attribute 'name'",).

Completing

import threading
threading.T

works fine.

Request: Use Sphinx docstring to infer type of function arguments

Sphinx info filed (http://sphinx.pocoo.org/domains.html#info-field-lists) has well defined syntax and it is used in many modules. It would be nice if Jedi can pull information out from it. Jedi user can quickly improve completions in their functions by improving their documentation.

Show builtin exceptions after raise

raise <tab>

This should show builtin exception classes.

Jedi does not care what is in sys.path

It looks like jedi does not care what is in sys.path when completing code.

Let's say I have a virtualenv ~/.virtualenvs/tmp which has numpy installed and numpy is not installed in system site-packages. If I start jedi using ~/.virtualenvs/tmp/bin/python jedi can complete numpy, but it cannot do it when I start jedi using /usr/bin/python and add numpy to sys.path.

This is how to reproduce. Save the following code in test.py:

import os
import sys
import jedi


def add_virtualenv_path():
    """Add virtualenv's site-packages to `sys.path`."""
    venv = os.path.abspath(os.getenv('VIRTUAL_ENV'))
    if not venv:
        return
    path = os.path.join(
        venv, 'lib', 'python%d.%d' % sys.version_info[:2], 'site-packages')
    sys.path.insert(0, path)


add_virtualenv_path()
import numpy  # this does not fail

source = """\
import numpy
numpy."""
script = jedi.Script(source, 2, len('numpy.'), '')

print script.complete()

Run test.py using /usr/bin/python, like this:

source ~/.virtualenvs/tmp/bin/activate
echo $VIRTUAL_ENV
/usr/bin/python test.py

This will output:

/home/takafumi/.virtualenvs/tmp
[]

If I run this script by python test.py, I get a long list of completions.

pydoc failure on windows

exception occurs on
jedi\parsing.py line 301
when os is windows and os.path.sep = ''

changing line 300 in the same file to
sep = (re.escape(os.path.sep),) * 2
can fix this issue.

goto() import following

I have been using get_definitions() to implement what is now the goto() function. This worked great until now. I tried using goto(), but there are these two issues.
When goto() is invoked on a name in an import statement that absolutely imports from within the current package, nothing is found. In my case it looks like this:
from myproject.mod import SomeClass
with the cursor on SomeClass. This used to work with get_definitions() and accessing scope.parent.
myproject is in sys.path.

Second, I would like to jump to the definition directly, without stopover at the import statement.

Are you planning to enhance goto() like this or do I need to implement this myself?

Anyway, great work!

slow in large files

When I install the plugin and open a file in python + - 400 lines, when it gets slow when I start typing. And when I type the point, it takes about 2 seconds to appear oa listing.

Remembering that this was a project in Django.

also in: davidhalter/jedi-vim#20

from @gilsondev (in another issue)

Switch between completing everything and only names in all in from imports

When completing here
from pkg.mod import <tab>
make it possible to only display names present in the module's __all__ list.
Realize this as a mapping, maybe only present when the popupmenu is open (toggle).

Request: Make the argument source_path for api.Script optional

Can source_path be optional for small source? How about source_path=None meaning "do not cache". For example it will be useful when using with IPython Notebook (https://github.com/tkf/emacs-ipython-notebook), as there is no actual Python file when writing code in the notebook.

Clarify how Jedi autocompletes

Hi.

To me, the most important thing when selecting whether to use autocomplete, and which one to use, is knowing what if anything is evaluated and what is done statically.

If possible, it would be extremely helpful to have specific documentation on what execution of code is being done when autocompleting. I haven't had a chance to dig through the source yet, but from just a quick peek it does seem like at least some is being done, so having clear lines for how far that goes would be lovely.

Thanks for your work!

imports + getattr completion

import django

class Foo(object):
    global django
    asdf = django

def asdfy():
    return Foo 

xorz = getattr(asdfy()(), 'asdf')
print xorz.<tab>

...doesn't work. Jedi sucks so much.

psycopg2

Completion does not work in these examples:

import psycopg2

conn = psycopg2.connect('dbname=test')
conn.<TAB>

import psycopg2

conn = psycopg2.connect('dbname=test')
cur = conn.cursor()
cur.<TAB>

Default description is too long

Sometimes Jedi returns very long description. It would be nice if it returns shorter one by default. I know it is on your TODO list as the source says so, but let me file this issue so that people can follow the status.

Note: This is how I am using it in Emacs Jedi:
https://github.com/tkf/emacs-jedi/blob/9ed6990f4f69f51a03c78218c9ec3d4b0654d9f1/jediepcserver.py#L64

Example:

Originally posted at tkf/emacs-jedi#4 by @syohex

Complete requests

import requests

r = requests.post('http://google.com', {'foo': 'bar'})
r.st<tab>

This should return r.status_code.

iterators + strings + getattr completion

class FooBar(object):
    raboof = 'fourtytwo'

target = u'' 
for char in reversed(['f', 'o', 'o', 'b', 'a', 'r']):
    target += char

answer = getattr(FooBar, target)
answer.<tab>

...doesn't work. Jedi sucks so much.

solved, please close this issue.

Strange 10s delay on getitem

See this file: http://tmp.dbrgn.ch/builder.py.txt

Go to line 124 in vim, move the cursor to the last character and press "a". A 10-15 seconds delay occurs.

At first it even gave me segfaults, after a recompilation of vim that doesn't happen anymore, but the long delay still persists.

Shifted CallDef.index for keyword argument

When in code like function(alpha='one', beta='two'), it seems that index=0 when the cursor is at alpha but index=1 when at 'one'. I think it should be index=0 for both cases.

In [2]:
import jedi

In [3]:
source = """\
def function(alpha, beta):
    pass
function(alpha='one', beta='two')"""
script = jedi.Script(source, 3, len("function(a"), '')
script.get_in_function_call().index
Out [3]:
0

In [4]:
source = """\
def function(alpha, beta):
    pass
function(alpha='one', beta='two')"""
script = jedi.Script(source, 3, len("function(alpha='on"), '')
script.get_in_function_call().index
Out [4]:
1

Request: explain why Script.goto/get_definition returns a list in docstring

If you don't know about Jedi internals it feels like returning a Definition object is the right thing to do. Why you are returning list? Which element I should use if I just want to show the docstring or goto the line of def function(...)?

Request: docstrings and Sphinx documentation?

It would be nice to have more docstrings and Sphinx documentation. For example, I need a couple of experiments to see the difference between Completion.word and Completion.complete.

Jedi with PyPy

Running Jedi on PyPy is no problem. (Almost) all tests pass.

But PyPy has a bug in current releases (itertools.tee):
https://bugs.pypy.org/issue1249
It got fixed a few hours ago.

If this fix of PyPy is in the major packaging systems, I will start supporting it (probably PyPy 2.0).

"AttributeError: 'Flow' object has no attribute 'name'" at dev head

Convert README to .rst

REStructuredText makes more sense because the README could be turned into a full Sphinx based documentation later on.

I'll probably do this tonight or tomorrow.

Name mangling of private variables

Currently jedi includes l.__iterable as completion of the code below. I think jedi should not return private variables such as this by default. And if it is to return such variables, name mangling rule [1] should be applied.

l = list('abc')
l.__

[1] http://docs.python.org/2/tutorial/classes.html#private-variables-and-class-local-references

meta classes + if + array indexing + setattr completion

Oh, you thought reverse iterators were too easy?

class _TrackingMetaclass(type):
    def __init__(cls, name, bases, attrs):
        if hasattr(cls, '_bazinga'):
            IncredibleClass._registry.append(cls)

class IncredibleClass(object):
    __metaclass__ = _TrackingMetaclass
    _registry = []

class Eggs(IncredibleClass):
    _bazinga = True

class Bacon(IncredibleClass):
    pass

class Spam(IncredibleClass):
    _bazinga = None
    number = '01189998819991197253'

yoda = Bacon()
setattr(yoda, '_omgwtf', Eggs._registry)
yoda._omgwtf[1].number.<tab>

...doesn't work. There you go, Jedi sucks so much!

☀️ Cheers! ☀️

Licensing

I think I will license Jedi with the GNU LGPL, what do you think?

Is anyone fond of GPL or BSD?

Request: Definition.fullname

It would be nice if I can get "full name" or "absolute path" of the function or class. For example, if I have

import json
l = json.load
l# <- cursor

then corresponding Definition.fullname should return "json.load". This is mainly for document lookup. For example, you can directly search this "full name" using online Sphinx document. In Emacs, you can directly go to the document using pydoc-info [1] or pylookup [2] if you have the "full name". Also, I think you can use objects.inv (intersphinx) [3] to get the direct link to online documents generated by sphinx (not only stdlib!). I guess even having objects.inv handing as a jedi feature makes sense.

The problem is that many functions and classes have real location different from what is written in the document. For example, os.path.join in Linux is actually posixpath.join and io.Bytes is _io.Bytes. Can jedi workaround this problem?

Features

As written in the README, these features might be supported in the future:

function annotations (py3k feature)
class decorators (py3k feature)
getattr() / getattr / getattribute
sys.path modifications
manipulations of instances outside the instance variables, without using functions
mro
relative imports
operation support -> __mul__, __add__, etc.
assert / isinstance

Which features are important for you? Vote for the ones you're interested in.
Are there any other features, you like to have in Jedi?

If you don't like Jedi, I also want to know why!

Cheers!

python3 import failure

Jedi does not work properly in Python 3.1.3, because local package
imports like

import parsing

don't work anymore. Changing these lines to

from . import parsing

, as 2to3 suggests, gets us in trouble with circular dependencies
between various modules.

As a workaround it's possible to add the jedi installation path to
sys.path at runtime.

-ap

Request: "Full name" for completion.

Is it possible to get full symbol name from api.Completion object? For example, when I am completing json.l, I can get "load" from Completion.word and "oad" from Completion.complete. But how can I get "json.load"?

BTW, I started Emacs binding: https://github.com/tkf/emacs-jedi

No definition found for `from pygments.formatters import TerminalFormatter`

In [2]:
source = """\
from pygments.formatters import TerminalFormatter
TerminalFormatter"""
lines = source.splitlines()
script = jedi.Script(source, len(lines), len(lines[-1]), None)
definition = script.get_definition()
definition
Out [2]:
[]

It's the same for the other classes in this module.

The beginning of pygments/formatters/__init__.py is something like this:

from pygments.formatters._mapping import FORMATTERS

ns = globals()
for fcls in FORMATTERS:
    ns[fcls.__name__] = fcls
del fcls

__all__ = ['get_formatter_by_name', 'get_formatter_for_filename',
           'get_all_formatters'] + [cls.__name__ for cls in FORMATTERS]

Probably it's too evil for Jedi to handle?

Why re.compile() is interpreted as str?

In [3]:
source = """\
import re
any_re = re.compile('.*')"""
lines = source.splitlines()
script = jedi.Script(source, len(lines), 1, None)
definition = script.get_definition()
[(d, d.full_name) for d in definition]
Out [3]:
[(<Definition class str>, '__builtin__.str'),
 (<Definition class SRE_Pattern>, '_sre.SRE_Pattern')]

Jedi says any_re can be __builtin__.str. How come?

I will write a patch for mapping _sre.SRE_Pattern later (but don't wait for me if you want to do it).

Complete `self` in `for` loop

    def __init__(self):                                                                                
        self.foo = 'bar'

        for root, dirs, files in os.walk(self.

self.<tab> is not completed inside the os.walk( function call. Apparently it has to do with the for loop.

Renaming bug

 149     response = HttpResponse(mimetype='application/pdf')

 151     response.write(pdf)

Renaming response on line 153 leads to:

 149     foobear = HttpResponse(mimetype='application/pdf')

 151     foobear.write(pdf)

Use CLASS information after `if isinstance(object, CLASS)` block

Currently,

source = """\
import datetime
if isinstance(obj, datetime.datetime):
    obj."""
script = jedi.Script(source, 3, 8, '')
script.complete()

works, but

source = """\
import datetime
if isinstance(obj, datetime.datetime):
    pass
obj."""
script = jedi.Script(source, 4, 4, '')
script.complete()

does not work.

I think having false-positive candidates in auto-completion is OK (better than nothing).

how to change mapping from <c-space>

Hi,

How can I change the mapping from to something else? I can't figure out where to do that in your code.

Thanks!

Nested list comprehensions cause parsing error

This expression causes an error:

[[int(v) for v in line.strip().split() if v] for line in ["123", "123", "123"] if line]

When called like this:

jedi.Script("[[int(v) for v in line.strip().split() if v] for line in [\"123\", \"123\", \"123\"] if line]", 0, 10, "test.py")

Jedi for Sublime Text (a start)

I just started a port of Jedi for Sublime Text (https://github.com/svaiter/SublimeJEDI).

I never wrote a plugin for Sublime, so I might be slow to have a reliable plugin, but if anyone is interested to contribute, please join the effort :)

(Thanks for this awesome piece of code David)
