gray

Less uncompromising Python code formatter.

Gray stands on the shoulders of giants:

• isort - imports sorting and more
• pyupgrade - automatically upgrades syntax for newer versions of Python
• add-trailing-comma
• unify - unify quotes style

Usage

usage:
        gray myapp.py
        gray myproj/ tests/
        gray --log-level debug --formatters isort,unify ~/app


Less uncompromising Python code formatter. Args that start with '--' (eg.
--log-level) can also be set in a config file (/Users/dizballanze/.gray or
/etc/gray.conf or ./gray.conf). Config file syntax allows: key=value,
flag=true, stuff=[a,b,c] (for details, see syntax at https://goo.gl/R74nmi).
If an arg is specified in more than one place, then commandline values
override config file values which override defaults.

positional arguments:
  paths                 Paths to format (default: (PosixPath('.'),))

optional arguments:
  -h, --help            show this help message and exit

Logging options:
  --log-level {debug,info,warning,error,fatal}
  --log-format {stream,color,json,syslog}

Formatters options:
  -f FORMATTERS, --formatters FORMATTERS

                        trailing-comma,isort,pyupgrade,unify)

isort options:
  --isort-line-length ISORT_LINE_LENGTH
                        isort section (default: 80)
  --isort-virtual-env ISORT_VIRTUAL_ENV
                        virtual env path (default:
                        /Users/dizballanze/apps/gray/env)
  --isort-include-trailing-comma ISORT_INCLUDE_TRAILING_COMMA
                        include a trailing comma on multi line imports
                        (default: 1)
  --isort-lines-after-imports ISORT_LINES_AFTER_IMPORTS

Git Hook

You can setup gray formatting before each commit with pre-commit git hook. Add following file to .git/hooks/pre-commit and make it executable with chmod +x .git/hooks/pre-commit.

#!/usr/bin/env python
from gray.hooks import git_pre_commit

exit(git_pre_commit(stop_on_modify=True))

If stop_on_modify argument is True, hook will prevent commit if there are any unstaged changes in files you about to commit.

Otherwise, any unstaged changes in this files will be added to the index by the hook.
