TiroTools

Assorted font production scripts, mostly involving either conversion of data between font development source formats, or manipulation of source formats.

All scripts in this repo are licensed under the MIT open source license.

Setup

It is recommended to create and activate a virtual environment in which to run the tools. From the top level, TiroTools folder:

# Create a new virtualenv
python3 -m venv venv
# Activate env
source venv/bin/activate
# Install dependencies
pip3 install -r requirements.txt

For subsequent use (presuming the requirements have not changed), only the second of those steps will be required.

Please see individual folder readme files for installation, usage, or dependency notes.
