otlLib: Routines for working with OpenType Layout
#################################################
.. toctree::
:maxdepth: 2
The ``fontTools.otlLib`` library provides routines to help you create the
subtables and other data structures you need when you are editing a font's
``GSUB`` and ``GPOS`` tables: substitution and positioning rules, anchors,
lookups, coverage tables and so on.

Common OpenType Layout Data Structures
--------------------------------------
.. automodule:: fontTools.otlLib.builder
:members: buildCoverage, buildLookup
------------------------------------
Low-level GSUB Table Lookup Builders
------------------------------------
These functions deal with the "simple" lookup types. See above for classes to
help build more complex lookups (contextual and chaining lookups).
.. automodule:: fontTools.otlLib.builder
:members: buildSingleSubstSubtable, buildMultipleSubstSubtable, buildAlternateSubstSubtable, buildLigatureSubstSubtable
--------------------------
GPOS Shared Table Builders
--------------------------
The functions help build the `GPOS shared tables <https://docs.microsoft.com/en-us/typography/opentype/spec/gpos#shared-tables-value-record-anchor-table-and-mark-array-table>`_
as defined in the OpenType spec: value records, anchors, mark arrays and
mark record tables.

GDEF Table Subtable Builders

These functions build subtables for elements of the ``GDEF`` table.
