isort your python imports for you so you don't have to.
|
|
|
|
isort is a Python utility / library to sort imports alphabetically, and automatically separated into sections.
|
|
It provides a command line utility, Python library and `plugins for various editors <https://github.com/timothycrosley/isort/wiki/isort-Plugins>`_ to quickly sort all your imports.
|
|
It currently cleanly supports Python 2.6 - 3.5 without any dependencies.

|
|
:alt: Example Usage
|
|
|
|
Before isort:
|
|
|
|
.. code-block:: python
|
|
|
|
from my_lib import Object
|
|
|
|
print("Hey")
|
|
|
|
import os
|
|
|
|
from my_lib import Object3
|
|
|
|
from my_lib import Object2
|
|
|
|
import sys
|
|
|
|
from third_party import lib15, lib1, lib2, lib3, lib4, lib5, lib6, lib7, lib8, lib9, lib10, lib11, lib12, lib13, lib14
|
|
|
|
import sys
|
|
|
|
from __future__ import absolute_import
|
|
|
|
from third_party import lib3
|
|
|
|
print("yo")
|
|
|
|
After isort:
|
|
|
|
.. code-block:: python
|
|
|
|
from __future__ import absolute_import
|
|
|
|
import os
|
|
import sys
|
|
|
|
from third_party import (lib1, lib2, lib3, lib4, lib5, lib6, lib7, lib8,
|
|
lib9, lib10, lib11, lib12, lib13, lib14, lib15)
|
|
|
|
from my_lib import Object, Object2, Object3
|
|
|
|
print("Hey")
|
|
print("yo")
|
|
|
|
Installing isort
|
|
================
|
|
|
|
Installing isort is as simple as:
|
|
|
|
.. code-block:: bash
|
|
|
|
pip install isort
|
|
|
|
or if you prefer
|
|
|
|
.. code-block:: bash
|
|
|
|
easy_install isort
|
|
|
|
Using isort
|
|
===========
|
|
|
|
**From the command line**:
|
|
|
|
.. code-block:: bash
|
|
|
|
isort mypythonfile.py mypythonfile2.py
|
|
|
|
or recursively:
|
|
|
|
.. code-block:: bash
|
|
|
|
isort -rc .
|
|
|
|
*which is equivalent to:*
|
|
|
|
.. code-block:: bash
|
|
|
|
isort **/*.py
|
|
|
|
or to see the proposed changes without applying them:
|
|
|
|
.. code-block:: bash
|
|
|
|
isort mypythonfile.py --diff
|
|
|
|
Finally, to atomically run isort against a project, only applying changes if they don't introduce syntax errors do:
|
|
|
|
.. code-block:: bash
|
|
|
|
isort -rc --atomic .
|
|
|
|
(Note: this is disabled by default as it keeps isort from being able to run against code written using a different version of Python)
|
|
|
|
**From within Python**:
|
|
|
|
.. code-block:: bash
|
|
|
|
from isort import SortImports
|
|
|
|
SortImports("pythonfile.py")
|
|
|
|
or:
|
|
|
|
.. code-block:: bash
|
|
|
|
from isort import SortImports
|
|
|
|
new_contents = SortImports(file_contents=old_contents).output
|
|
|
|
**From within Kate:**
|
|
|
|
.. code-block:: bash
|
|
|
|
ctrl+[
|
|
|
|
or:
|
|
|
|
.. code-block:: bash
|
|
|
|
menu > Python > Sort Imports
|
|
|
|
Installing isort's Kate plugin
|
|
==============================
|
|
|
|
For KDE 4.13+ / Pate 2.0+:
|
|
|
|
.. code-block:: bash
|
|
|
|
wget https://raw.github.com/timothycrosley/isort/master/kate_plugin/isort_plugin.py --output-document ~/.kde/share/apps/kate/pate/isort_plugin.py
|
|
wget https://raw.github.com/timothycrosley/isort/master/kate_plugin/isort_plugin_ui.rc --output-document ~/.kde/share/apps/kate/pate/isort_plugin_ui.rc
|
|
wget https://raw.github.com/timothycrosley/isort/master/kate_plugin/katepart_isort.desktop --output-document ~/.kde/share/kde4/services/katepart_isort.desktop
|
|
|
|
For all older versions:
|
|
|
|
.. code-block:: bash
|
|
|
|
wget https://raw.github.com/timothycrosley/isort/master/kate_plugin/isort_plugin_old.py --output-document ~/.kde/share/apps/kate/pate/isort_plugin.py
|
|
|
|
You will then need to restart kate and enable Python Plugins as well as the isort plugin itself.
|
|
|
|
Installing isort's for your preferred text editor
|
|
=================================================
|
|
|
|
Several plugins have been written that enable to use isort from within a variety of text-editors.
|
|
You can find a full list of them `on the isort wiki <https://github.com/timothycrosley/isort/wiki/isort-Plugins>`_.
|
|
Additionally, I will enthusiastically accept pull requests that include plugins for other text editors
|
|
and add documentation for them as I am notified.
|
|
|
|
How does isort work?
|
|
====================
|
|
|
|
isort parses specified files for global level import lines (imports outside of try / except blocks, functions, etc..)
|
|
and puts them all at the top of the file grouped together by the type of import:
|
|
|
|
- Future
|
|
- Python Standard Library
|
|
- Third Party
|
|
- Current Python Project
|
|
- Explicitly Local (. before import, as in: ``from . import x``)
|
|
- Custom Separate Sections (Defined by forced_separate list in configuration file)
|
|
- Custom Sections (Defined by sections list in configuration file)
|
|
|
|
Inside of each section the imports are sorted alphabetically. isort automatically removes duplicate python imports,
|
|
and wraps long from imports to the specified line length (defaults to 80).
|
|
|
|
When will isort not work?
|
|
=========================
|
|
|
|
If you ever have the situation where you need to have a try / except block in the middle of top-level imports or if
|
|
your import order is directly linked to precedence.
|
|
|
|
For example: a common practice in Django settings files is importing * from various settings files to form
|
|
a new settings file. In this case if any of the imports change order you are changing the settings definition itself.
|
|
|
|
However, you can configure isort to skip over just these files - or even to force certain imports to the top.
|
|
|
|
Configuring isort
|
|
=================
|
|
|
|
If you find the default isort settings do not work well for your project, isort provides several ways to adjust
|
|
the behavior.
|
|
|
|
To configure isort for a single user create a ``~/.isort.cfg`` file:
|
|
|
|
.. code-block:: ini
|
|
|
|
[settings]
|
|
line_length=120
|
|
force_to_top=file1.py,file2.py
|
|
skip=file3.py,file4.py
|
|
known_future_library=future,pies
|
|
known_standard_library=std,std2
|
|
known_third_party=randomthirdparty
|
|
known_first_party=mylib1,mylib2
|
|
indent=' '
|
|
multi_line_output=3
|
|
length_sort=1
|
|
forced_separate=django.contrib,django.utils
|
|
default_section=FIRSTPARTY
|
|
|
|
Additionally, you can specify project level configuration simply by placing a ``.isort.cfg`` file at the root of your
|
|
project. isort will look up to 25 directories up, from the file it is ran against, to find a project specific configuration.
|
|
|
|
Or, if you prefer, you can add an isort section to your project's ``setup.cfg`` or ``tox.ini`` file with any desired settings.
|
|
|
|
You can then override any of these settings by using command line arguments, or by passing in override values to the
|
|
SortImports class.
|
|
|
|
Finally, as of version 3.0 isort supports editorconfig files using the standard syntax defined here:
|
|
http://editorconfig.org/
|
|
|
|
Meaning you place any standard isort configuration parameters within a .editorconfig file under the ``*.py`` section
|
|
and they will be honored.
|
|
|
|
For a full list of isort settings and their meanings `take a look at the isort wiki <https://github.com/timothycrosley/isort/wiki/isort-Settings>`_.
|
|
|
|
Multi line output modes
|
|
=======================
|
|
|
|
You will notice above the "multi_line_output" setting. This setting defines how from imports wrap when they extend
|
|
past the line_length limit and has 6 possible settings:
|
|
|
|
**0 - Grid**
|
|
|
|
.. code-block:: python
|
|
|
|
from third_party import (lib1, lib2, lib3,
|
|
lib4, lib5, ...)
|
|
|
|
**1 - Vertical**
|
|
|
|
.. code-block:: python
|
|
|
|
from third_party import (lib1,
|
|
lib2,
|
|
lib3
|
|
lib4,
|
|
lib5,
|
|
...)
|
|
|
|
**2 - Hanging Indent**
|
|
|
|
.. code-block:: python
|
|
|
|
from third_party import \
|
|
lib1, lib2, lib3, \
|
|
lib4, lib5, lib6
|
|
|
|
**3 - Vertical Hanging Indent**
|
|
|
|
.. code-block:: python
|
|
|
|
from third_party import (
|
|
lib1,
|
|
lib2,
|
|
lib3,
|
|
lib4,
|
|
)
|
|
|
|
**4 - Hanging Grid**
|
|
|
|
.. code-block:: python
|
|
|
|
from third_party import (
|
|
lib1, lib2, lib3, lib4,
|
|
lib5, ...)
|
|
|
|
**5 - Hanging Grid Grouped**
|
|
|
|
.. code-block:: python
|
|
|
|
from third_party import (
|
|
lib1, lib2, lib3, lib4,
|
|
lib5, ...
|
|
)
|
|
|
|
**6 - NOQA**
|
|
|
|
.. code-block:: python
|
|
|
|
from third_party import lib1, lib2, lib3, ... # NOQA
|
|
|
|
Alternatively, you can set ``force_single_line`` to ``True`` (``-sl`` on the command line) and every import will appear on its
|
|
own line:
|
|
|
|
.. code-block:: python
|
|
|
|
from third_party import lib1
|
|
from third_party import lib2
|
|
from third_party import lib3
|
|
...
|
|
|
|
Note: to change the how constant indents appear - simply change the indent property with the following accepted formats:
|
|
* Number of spaces you would like. For example: 4 would cause standard 4 space indentation.
|
|
* Tab
|
|
* A verbatim string with quotes around it.
|
|
|
|
For example:
|
|
|
|
.. code-block:: python
|
|
|
|
" "
|
|
|
|
is equivalent to 4.
|
|
|
|
For the import styles that use parentheses, you can control whether or not to
|
|
include a trailing comma after the last import with the ``include_trailing_comma``
|
|
option (defaults to ``False``).
|
|
|
|
Intelligently Balanced Multi-line Imports
|
|
=========================================
|
|
|
|
As of isort 3.1.0 support for balanced multi-line imports has been added.
|
|
With this enabled isort will dynamically change the import length to the one that produces the most balanced grid,
|
|
while staying below the maximum import length defined.
|
|
|
|
Example:
|
|
|
|
.. code-block:: python
|
|
|
|
from __future__ import (absolute_import, division,
|
|
print_function, unicode_literals)
|
|
|
|
Will be produced instead of:
|
|
|
|
.. code-block:: python
|
|
|
|
from __future__ import (absolute_import, division, print_function,
|
|
unicode_literals)
|
|
|
|
To enable this set ``balanced_wrapping`` to ``True`` in your config or pass the ``-e`` option into the command line utility.
|
|
|
|
Custom Sections and Ordering
|
|
============================
|
|
|
|
You can change the section order with ``sections`` option from the default of:
|
|
|
|
.. code-block:: ini
|
|
|
|
FUTURE,STDLIB,THIRDPARTY,FIRSTPARTY,LOCALFOLDER
|
|
|
|
to your preference:
|
|
|
|
.. code-block:: ini
|
|
|
|
sections=FUTURE,STDLIB,FIRSTPARTY,THIRDPARTY,LOCALFOLDER
|
|
|
|
You also can define your own sections and their order.
|
|
|
|
Example:
|
|
|
|
.. code-block:: ini
|
|
|
|
known_django=django
|
|
known_pandas=pandas,numpy
|
|
sections=FUTURE,STDLIB,DJANGO,THIRDPARTY,PANDAS,FIRSTPARTY,LOCALFOLDER
|
|
|
|
would create two new sections with the specified known modules.
|
|
|
|
Auto-comment import sections
|
|
============================
|
|
|
|
Some projects prefer to have import sections uniquely titled to aid in identifying the sections quickly
|
|
when visually scanning. isort can automate this as well. To do this simply set the ``import_heading_{section_name}``
|
|
setting for each section you wish to have auto commented - to the desired comment.
|
|
|
|
For Example:
|
|
|
|
.. code-block:: ini
|
|
|
|
import_heading_stdlib=Standard Library
|
|
import_heading_firstparty=My Stuff
|
|
|
|
Would lead to output looking like the following:
|
|
|
|
.. code-block:: python
|
|
|
|
# Standard Library
|
|
import os
|
|
import sys
|
|
|
|
import django.settings
|
|
|
|
# My Stuff
|
|
import myproject.test
|
|
|
|
Ordering by import length
|
|
=========================
|
|
|
|
isort also makes it easy to sort your imports by length, simply by setting the ``length_sort`` option to ``True``.
|
|
This will result in the following output style:
|
|
|
|
.. code-block:: python
|
|
|
|
from evn.util import (
|
|
Pool,
|
|
Dict,
|
|
Options,
|
|
Constant,
|
|
DecayDict,
|
|
UnexpectedCodePath,
|
|
)
|
|
|
|
Skip processing of imports (outside of configuration)
|
|
=====================================================
|
|
|
|
To make isort ignore a single import simply add a comment at the end of the import line containing the text ``isort:skip``:
|
|
|
|
.. code-block:: python
|
|
|
|
import module # isort:skip
|
|
|
|
or:
|
|
|
|
.. code-block:: python
|
|
|
|
from xyz import (abc, # isort:skip
|
|
yo,
|
|
hey)
|
|
|
|
To make isort skip an entire file simply add ``isort:skip_file`` to the module's doc string:
|
|
|
|
.. code-block:: python
|
|
|
|
""" my_module.py
|
|
Best module ever
|
|
|
|
isort:skip_file
|
|
"""
|
|
|
|
import b
|
|
import a
|
|
|
|
Adding an import to multiple files
|
|
==================================
|
|
|
|
isort makes it easy to add an import statement across multiple files, while being assured it's correctly placed.
|
|
|
|
>From the command line:
|
|
|
|
.. code-block:: bash
|
|
|
|
isort -a "from __future__ import print_function" *.py
|
|
|
|
from within Kate:
|
|
|
|
.. code-block::
|
|
|
|
ctrl+]
|
|
|
|
or:
|
|
|
|
.. code-block::
|
|
|
|
menu > Python > Add Import
|
|
|
|
Removing an import from multiple files
|
|
======================================
|
|
|
|
isort also makes it easy to remove an import from multiple files, without having to be concerned with how it was originally
|
|
formatted.
|
|
|
|
>From the command line:
|
|
|
|
.. code-block:: bash
|
|
|
|
isort -r "os.system" *.py
|
|
|
|
from within Kate:
|
|
|
|
.. code-block::
|
|
|
|
ctrl+shift+]
|
|
|
|
or:
|
|
|
|
.. code-block::
|
|
|
|
menu > Python > Remove Import
|
|
|
|
Using isort to verify code
|
|
==========================
|
|
|
|
The ``--check-only`` option
|
|
---------------------------
|
|
|
|
isort can also be used to used to verify that code is correctly formatted by running it with ``-c``.
|
|
Any files that contain incorrectly sorted and/or formatted imports will be outputted to ``stderr``.
|
|
|
|
.. code-block:: bash
|
|
|
|
isort **/*.py -c -vb
|
|
|
|
SUCCESS: /home/timothy/Projects/Open_Source/isort/isort_kate_plugin.py Everything Looks Good!
|
|
ERROR: /home/timothy/Projects/Open_Source/isort/isort/isort.py Imports are incorrectly sorted.
|
|
|
|
One great place this can be used is with a pre-commit git hook, such as this one by @acdha:
|
|
|
|
https://gist.github.com/acdha/8717683
|
|
|
|
This can help to ensure a certain level of code quality throughout a project.
|
|
|
|
|
|
Git hook
|
|
--------
|
|
|
|
isort provides a hook function that can be integrated into your Git pre-commit script to check
|
|
Python code before committing.
|
|
|
|
To cause the commit to fail if there are isort errors (strict mode), include the following in
|
|
``.git/hooks/pre-commit``:
|
|
|
|
.. code-block:: python
|
|
|
|
#!/usr/bin/env python
|
|
import sys
|
|
from isort.hooks import git_hook
|
|
|
|
sys.exit(git_hook(strict=True))
|
|
|
|
If you just want to display warnings, but allow the commit to happen anyway, call ``git_hook`` without
|
|
the `strict` parameter.
|
|
|
|
Setuptools integration
|
|
----------------------
|
|
|
|
Upon installation, isort enables a ``setuptools`` command that checks Python files
|
|
declared by your project.
|
|
|
|
Running ``python setup.py isort`` on the command line will check the files
|
|
listed in your ``py_modules`` and ``packages``. If any warning is found,
|

the command will exit with an error code:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ python setup.py isort
|
|
|
|
Also, to allow users to be able to use the command without having to install
|
|
isort themselves, add isort to the setup_requires of your ``setup()`` like so:
|
|
|
|
.. code-block:: python
|
|
|
|
setup(
|
|
name="project",
|
|
packages=["project"],
|
|
|
|
setup_requires=[
|
|
"isort"
|
|
]
|
|
)
|
|
|
|
|
|
Why isort?
|
|
==========
|
|
|
|
isort simply stands for import sort. It was originally called "sortImports" however I got tired of typing the extra
|
|
characters and came to the realization camelCase is not pythonic.
|
|
|
|
I wrote isort because in an organization I used to work in the manager came in one day and decided all code must
|
|
have alphabetically sorted imports. The code base was huge - and he meant for us to do it by hand. However, being a
|
|
programmer - I'm too lazy to spend 8 hours mindlessly performing a function, but not too lazy to spend 16
|
|
hours automating it. I was given permission to open source sortImports and here we are :)

Thanks and I hope you find isort useful!
