aspy.refactor_imports

Utilities for refactoring imports in python-like syntax.

Installation

pip install aspy.refactor_imports

Examples

aspy.refactor_imports.import_obj

Constructing an import object

>>> from aspy.refactor_imports.import_obj import FromImport
>>> from aspy.refactor_imports.import_obj import ImportImport
>>> FromImport.from_str('from foo import bar').to_text()
'from foo import bar\n'
>>> ImportImport.from_str('import bar as baz').to_text()
'import bar as baz\n'

Splitting an import object

>>> from aspy.refactor_imports.import_obj import ImportImport
>>> obj = ImportImport.from_str('import foo, bar, baz')
>>> [i.to_text() for i in obj.split_imports()]
['import foo\n', 'import bar\n', 'import baz\n']

Sorting import objects

>>> import pprint
>>> from aspy.refactor_imports.import_obj import FromImport
>>> objs = sorted([
    FromImport.from_str('from a import foo'),
    FromImport.from_str('from a.b import baz'),
    FromImport.from_str('from a import bar'),
    FromImport.from_str('from a import bar as buz'),
    FromImport.from_str('from a import bar as baz'),
])
>>> pprint.pprint([i.to_text() for i in objs])
['from a import bar\n',
 'from a import bar as baz\n',
 'from a import bar as buz\n',
 'from a import foo\n',
 'from a.b import baz\n']

# Or to partition into blocks (even with mixed imports)
>>> import buck.pprint as pprint
>>> from aspy.refactor_imports.import_obj import FromImport
>>> from aspy.refactor_imports.import_obj import ImportImport
>>> from aspy.refactor_imports.sort import sort
>>> partitioned = sort(
    [
        FromImport.from_str('from aspy import refactor_imports'),
        ImportImport.from_str('import sys'),
        FromImport.from_str('from pyramid.view import view_config'),
        ImportImport.from_str('import cached_property'),
    ],
    separate=True,
    import_before_from=True,
))
>>> pprint.pprint(partitioned)
(
    (ImportImport.from_str('import sys\n'),),
    (
        ImportImport.from_str('import cached_property\n'),
        FromImport.from_str('from pyramid.view import view_config\n'),
    ),
    (FromImport.from_str('from aspy import refactor_imports\n'),),
)

aspy.refactor_imports.classify

Classify a module

>>> from aspy.refactor_imports.classify import classify_import
>>> classify_import('__future__')
'FUTURE'
>>> classify_import('aspy')
'APPLICATION'
>>> classify_import('pyramid')
'THIRD_PARTY'
>>> classify_import('os')
'BUILTIN'
>>> classify_import('os.path')
'BUILTIN'

Also as convenient constants

## From aspy.refactor_imports.classify


class ImportType(object):
    __slots__ = ()

    FUTURE = 'FUTURE'
    BUILTIN = 'BUILTIN'
    THIRD_PARTY = 'THIRD_PARTY'
    APPLICATION = 'APPLICATION'

    __all__ = (FUTURE, BUILTIN, THIRD_PARTY, APPLICATION)
