alignment

>>> from pyaliner import align, COMPACT

>>> align('Example invalid invalid sentence'.split(), 'Example sentence'.split())
(('Example', 'invalid', 'invalid', 'sentence'), ('Example', '⎵', '⎵', 'sentence'))

>>> align('Example invalid invalid sentence'.split(), 'Example sentence'.split(), kind=COMPACT)
(('Example', 'invalid∙invalid', 'sentence'), ('Example', '⎵', 'sentence'))

Limitations

• Three-way alignment uses a slow heuristic.
• Wide characters, e.g., East Asian scripts, are not properly aligned with narrow ones
