.. py:class:: magnum.text.FontManager
:summary: Manager for :ref:`AbstractFont` plugin instances
Each plugin returned by :ref:`instantiate()` or :ref:`load_and_instantiate()`
references its owning :ref:`FontManager` through
:ref:`AbstractFont.manager`, ensuring the manager is not deleted before the
plugin instances are.
.. TODO couldn't the plugin_interface etc. docs be parsed from pybind's docs?
repeating them for every plugin is annoying
.. py:class:: magnum.text.AbstractFont
:data plugin_interface: Plugin interface string
:data plugin_search_paths: Plugin search paths
:data plugin_suffix: Plugin suffix
:data plugin_metadata_suffix: Plugin metadata suffix
Similarly to C++, font plugins are loaded through :ref:`FontManager`:
..
>>> from magnum import text
.. code:: py
>>> manager = text.FontManager()
>>> font = manager.load_and_instantiate('StbTrueTypeFont')
Unlike C++, errors in both API usage and file parsing are reported by
raising an exception. See particular function documentation for detailed
behavior.
.. py:function:: magnum.text.AbstractFont.open_data
:raise RuntimeError: If file opening fails
.. py:function:: magnum.text.AbstractFont.open_file
:raise RuntimeError: If file opening fails
For compatibility with :ref:`os.path`, on Windows this function converts
all backslashes in :p:`filename` to forward slashes before passing it to
:dox:`Text::AbstractFont::openFile()`, which expects forward slashes as
directory separators on all platforms.

.. py:enum:: magnum.text.Feature
The equivalent to C++ :dox:`Text::feature()` is passing the four-character
code to the constructor:
..
>>> from magnum import text
.. code:: pycon
>>> feature = text.Feature('kern')
>>> feature.name
'KERNING'
.. py:enum:: magnum.text.Script
The equivalent to C++ :dox:`Text::script()` is passing the four-character
code to the constructor:
..
>>> from magnum import text
.. code:: pycon
>>> script = text.Script('Latn')
>>> script.name
'LATIN'
