Fontra is an in-development browser-based font editor. It consists of two main parts:

• Fontra client — runs in the browser, written in JavaScript
• Fontra server — runs locally or on a remote machine, written in Python

• Check out the repo, cd into the root of the repo

• Ensure you have Python >= 3.10 installed, preferably from python.org

• Create a Python venv in the root of the repo:

  python3 -m venv venv --prompt=fontra

• Activate venv:

  source venv/bin/activate

• Install dependencies:

  pip install --upgrade pip

  pip install -r requirements.txt

  pip install -e .

• Start the fontra server with a path to a folder containing fonts (.designspace, .ufo, .ttf or .otf), using the filesystem subcommand:

  fontra --launch filesystem /path/to/a/folder

• The default browser will then navigate to:

  http://localhost:8000/

• To use Fontra with .rcjk data on disk, or to connect to a remote rcjk server, install the fontra-rcjk plugin package. Then you can start it with a robocjk server hostname, using the rcjk subcommand provided by the fontra-rcjk plugin:

  fontra --launch rcjk some-robocjk-server.some-domain.com
