What is this?
~~~~~~~~~~~~~
| fontTools is a library for manipulating fonts, written in Python. The
project includes the TTX tool, that can convert TrueType and OpenType
fonts to and from an XML text format, which is also called TTX. It
supports TrueType, OpenType, AFM and to an extent Type 1 and some
Mac-specific formats. The project has an `MIT open-source
license `__.
| Among other things this means you can use it free of charge.
[User documentation] and
[developer documentation]
are available at [Read the Docs].
Installation
~~~~~~~~~~~~
FontTools requires [Python] 3.9
or later. We try to follow the same schedule of minimum Python version
support as
NumPy (see [NEP 29]).
The package is listed in the Python Package Index (PyPI), so you can
install it with [pip]:

requirement (#3831).
- [feaLib] Improve single substitution promotion to multiple/ligature
substitutions, fixing a few bugs as well (#3849).
- [loggingTools] Make ``Timer._time`` a static method that doesn't take
self, makes it easier to override (#3836).

offset in the compiled table (#3850).
- [feaLib] Raise an error on conflicting ligature substitution rules
instead of silently taking the last one (#3835).
- Add typing annotations to T2CharStringPen (#3837).
- [feaLib] Add single substitutions that were promoted to multiple or
ligature substitutions to aalt feature (#3847).
- [featureVars] Create a default LangSys in a ScriptRecord if missing when

- [varLib] Ensure that instances only reuse name ID 2 or 17 if they are at
the default location across all axes (#3831).
- [varLib] Create a dflt LangSys in a ScriptRecord when adding variations
later, to fix an avoidable crash in an edge case (#3838).
