SMufoLib: Where SMuFL meets UFO
===============================

SMufoLib is a small Python library designed to aid in font development
and scripting specific to the `Standard Music Font Layout
<https://w3c.github.io/smufl/latest/>`_ (SMuFL). As an extension of the
`FontParts <https://fontparts.robotools.dev/en/stable/index.html>`_
API, SMufoLib relies on the platform and application independent
`Unified Font Object <https://unifiedfontobject.org>`_ (UFO) format and
the command line, rather than any particular font editor.

Documentation
-------------

SMufoLib’s documentation is available at `smufolib.readthedocs.io
<https://smufolib.readthedocs.io/en/latest/index.html>`_.

Installation
------------

SMufoLib requires `Python <http://www.python.org/download/>`__ 3.10 or
later. It is listed in the `Python Package Index
<https://pypi.org/project/smufolib>`_ (PyPI) and can be installed with
`pip <https://pip.pypa.io/>`__:

.. code:: bash

   $ python -m pip install smufolib

Scripts
-------

SMufoLib comes bundled with several useful scripts for building SMuFL
metadata files, calculating engraving defaults from glyphs, importing
identification attributes and more.

Scripts may be run either directly from the command line or imported as
regular python modules, passing in any arguments in the familiar manner
to each platform.

As an example, check for missing or superflous SMuFL anchors and mark
discrepant glyphs by running the `checkAnchors` script with
the ``--mark`` flag directly from the command line:

.. code:: zsh

   $ check-anchors path/to/my/font.ufo --mark

Positional arguments and available options can be listed by running the
help command on the script:

.. code:: zsh

   $ check-anchors --help

   usage: check-anchors [-h] [-F FONTDATA] [-m] [-c COLOR COLOR COLOR COLOR] [-v]
                        font

   Find missing or superfluous SMuFL anchors.

   positional arguments:
      font                  path to UFO file

   options:
      -h, --help           show this help message and exit
      -F FONTDATA, --font-data FONTDATA
                           path to font metadata file (default: <Request '/url/path
                           /to/reference/font/metadata.json' ('/file/path/to/refere
                           nce/font/metadata.json') at 4536666000>)
      -m, --mark           apply defined color values to objects (default: False)
      -c COLOR COLOR COLOR COLOR, --color COLOR COLOR COLOR COLOR
                           list of RGBA color values (default: None)
      -v, --verbose        make output verbose (default: False)


Alternatively, scripts can be imported as modules in Python:

.. code:: Py3

   from bin.checkAnchors import checkAnchors

   checkAnchors(mark=True)

This imports and executes the script's program
function `checkAnchors` from the script module of the same
name.
