TR Core TR GUI GitHub last commit


TypeRig is a Python library aimed at simplifying the current FontLab API while offering some additional functionality that is heavily biased towards a simultaneous multi-layered workflow. As TypeRig (TR) is under rapid development in the last couple of years, please do update frequently.

Important note

If you are experiencing any trouble running your scripts after April 2021 please refer to our latest Py2.7 release. It is a snapshot before switching the TR core to Py3+ and refactoring most scripts to be both Py2.7 and Py3+ compatible.


Please refer to the following work in progress document.

Point the app towards ./Scripts/Delta Machine and ./Scripts/GUI.
