CLI Usage

Usage: pip-split-requirements [OPTIONS] REQUIREMENTS_FILE...

  Split a pip requirements file into multiple files according to patterns.

  Comment lines are ignored. Option lines are emitted in all groups.

Arguments:
  REQUIREMENTS_FILE...  [required]

Options:
  -g, --group-spec TEXT           Group specifications in form name:pattern.
  -p, --prefix TEXT               Each requirements group file will be named
                                  {prefix}-{group_name}.txt. The prefix can
                                  contain path separators, to generate files
                                  into a chosen directory.  [default:
                                  requirementsgroup]
  --default-group / --no-default-group
                                  Automatically append a group named 'other',
                                  matching all lines not matched by other
                                  groups.  [default: default-group]
  --help                          Show this message and exit.

Usage as a pre-commit hook

    hooks:
      - id: pip-split-requirements
        files: ^requirements\.txt$
        args:
