Abjad 2.17

Improvements:

• Abjad's documentation has seen extensive work, including:
  • a new theme based off of https://github.com/snide/sphinx_rtd_theme
  • crisp SVG Graphviz output for all class lineage graphs
  • expandable image thumbnails
  • a score gallery page showing notation examples from many scores created with Abjad
  • revised installation instructions
  • virtually all code examples in the docs are now interpreted via the abjad-book Sphinx extension, guaranteeing correctness
  • many enhancements to Abjad's Sphinx extension
• A new PackageGitCommitToken class for embedding Python package version information in LilyPond files.
• A new IterationAgent.by_timeline_and_logical_tie() method.
• A provisional collection of new classes in lilypondnametools for object-modeling various LilyPond entities: LilyPondGrob, LilyPondGrobInterface, LilyPondContext and LilyPondEngraver.
• Abjad now supports PyPy.

Changes:

• Abjad's dependencies have been separated into standard, development and ipython. See our installation docs for details.
• Abjad's IPython extension now uses timidity instead of ffmpeg and fluidsynth to embed audio output from calls to play(). OSX users can install timidity via HomeBrew.
• GraphvizEdge.__call__() has been removed in favor of explicit .attach(node_one, node_two) and .detach() methods.
• sievetools functionality has been merged into the classes housed in patterntools.
• All labeltools functionality has been migrated into the agentools.LabelAgent class.
• LilyPondFile properties such as paper_size, includes, etc. are now immutable. Set them during instantiation. See the API example for details.
• TimeSignature can now only be instantiated from a pair, such as (3, 4): TimeSignature((3, 4)).

Bugfixes:

• GraphvizGraph instances can now be copied with edges intact.
• Markup now properly quotes strings containing # symbols.
