importformatter 0.1.3

Groups, lexicographically sorts and formats import statement into the three groups as defined by PEP8 (standard library, third-party packages, current package/application.)

Imports from the same package are collapsed into a single statement, and multiple identifiers from the same packages are grouped using parentheses and separated by a newline.

Usage

Usage: format-imports.py [options]

Groups, sorts, and formats import statements.

Options:
-h, --help            show this help message and exit
-a APPLICATION, --application=APPLICATION
-s STDLIB_FILES, --stdlib-file=STDLIB_FILES
                        File(s) containing additional module names to add to
                        the standard library set.

The script accepts input via stdin, and outputs the formatted code via stdout.

Example

For the given bad.py:

import sys

import foo
import bar as other
from baz import (
    package,
    package3,
)
from module import package3 as package4
from baz import package2, package1

import application
from application.utils import memoize
from application.models import User
from application.models import Place

import os

The output of format-imports.py -a application < bad.py will be:

import os
import sys

import bar as other
import foo
from baz import (
    package,
    package1,
    package2,
    package3,
)
from module import package3 as package4

import application
from application.models import (
    Place,
    User,
)
from application.utils import memoize

Usage with Vim

Select a chunk of text in visual mode, then invoke the format-imports.py script against the chunk with:

:'<,'>!format-imports.py -a <application>
