kern-convertor 0.1.1

Python script to convert font kerning data from Adobe fea format to UFO plist format and vice-versa

kern-convertor

kern-convertor is a Python utility for converting kerning data in AFDKO features.fea format into UFO-compatible groups.plist and kerning.plist files.

Features

• Converts AFDKO-style kerning features into UFO-format kerning and group files for direct use in font editors or build processes.​

• Command-line interface for batch processing kerning data from feature files.​

• The fea2kern.py script provides the ability to convert UFO-format groups.plist and kerning.plist files back into Adobe FEA (features) syntax.

Installation

Install via pip from PyPI:

pip install kern-convertor

Usage

After installation, kern-convertor provides command-line scripts to generate kerning and group files from Adobe Feature File and vice-versa :

Convert Adobe Feature file to UFO plist format

To convert a features file to groups.plist:

kern-groups features.fea groups.plist

To convert kerning pairs to kerning.plist:

kern-convertor features.fea kerning.plist

Replace features.fea with the path to your AFDKO features file. Output .plist files can be copied into the appropriate UFO font directory.​

Example

To convert your kerning feature file and save the outputs in the current directory:

kern-groups path/to/features.fea groups.plist
kern-convertor path/to/features.fea kerning.plist

Convert kerning data in ufo plist format to Adobe Fea format

fea2kern script converts existing UFO groups.plist and kerning.plist files to a FEA features format file.

Command

fea2kern path/to/groups.plist path/to/kerning.plist output.fea

The first argument is the path to groups.plist

The second argument is the path to kerning.plist

The third argument is the output .fea filename

Example

To generate an Adobe FEA kerning feature from UFO data:

fea2kern groups.plist kerning.plist features.fea

This command writes an AFDKO FEA kerning feature, reconstructed from the groups.plist and kerning.plist files, to features.fea.

Requirements

This tool requires Python 3.7 or later. Any additional dependencies will be installed automatically via pip.​
