Looping through font binaries in DrawBot

A quick exploration of looping through all glyphs in a font binary (TTF or OTF). Probably a WIP.

Useful in cases such as:

• Exporting an icon font to SVGs or PNGs, etc
• Making a PDF to proofing every glyph in a font

Usage

Set up the environment

To build, set up the virtual environment

virtualenv -p python3 venv

Then activate it:

source venv/bin/activate

Then install requirements:

pip install -U -r requirements.txt

Run the scripts

Run the desired DrawBot script in a terminal:

python source/export-ttf-to-svg.py

python source/export-ttf-chars-to-svg.py # warning: this one can take a while for a large font!

To alter the font, replace source/RecursiveMonoCslSt-Med.ttf with any ttf or otf font, then update the drawbot scripts to point to that new file path.
