absolufy-imports 0.3.0

A tool to automatically replace relative imports with absolute ones.

absolufy-imports

A tool and pre-commit hook to automatically convert relative imports to absolute.

Installation

$ pip install absolufy-imports

Usage as a pre-commit hook (recommended)

See pre-commit for instructions

Sample .pre-commit-config.yaml:

-   repo: https://github.com/MarcoGorelli/absolufy-imports
    rev: v0.3.0
    hooks:
    -   id: absolufy-imports

Command-line example

$ cat mypackage/myfile.py
from . import __version__
$ absolufy-imports mypackage/myfile.py
$ cat mypackage/myfile.py
from mypackage import __version__

Configuration

Application directories

If your package follows the popular ./src layout, you can pass your application directories via --application-directories, e.g.

$ cat src/mypackage/myfile.py
from . import __version__
$ absolufy-imports src/mypackage/myfile.py --application-directories src
$ cat src/mypackage/myfile.py
from mypackage import __version__

Multiple application directories should be comma-separated, e.g. --application-directories .:src. This is the same as in reorder-python-imports.

Only use relative imports

Use the --never flag, e.g.

$ cat mypackage/myfile.py
from mypackage import __version__
$ absolufy-imports mypackage/myfile.py --never
$ cat mypackage/myfile.py
from . import __version__

Keep submodules relative

Use the --keep-submodules-relative flag. By default, submodules are considered to be the first level of the directory. E.g. if you have

├── mypackage
│   ├── library1
│   │   ├── foo.py
│   │   └── subdirectory
│   │       ├── bar.py
│   │       └── baz.py
│   └── library2
│       └── qux.py

and

$ cat mypackage/library1/subdirectory/bar.py
from mypackage.library1.subdirectory import baz
from mypackage.library1 import foo
from mypackage.library2 import qux

then you will get

$ absolufy-imports mypackage/library1/subdirectory/bar.py --keep-submodules-relative
$ cat mypackage/library1/subdirectory/bar.py
from . import baz
from .. import foo
from mypackage.library2 import qux

To specify a custom list of submodules, you can use the --submodules flag, e.g.

$ absolufy-imports mypackage/library1/subdirectory/bar.py \
  --keep-submodules-relative \
  --submodules '{".": ["mypackage.library1", "mypackage.library2"]}'

Note that they need to be in json format, and the keys should be the application directories.
