Hello and welcome to coldtype, an odd little library for programmatic typography, written for use on Goodhertz projects and text animations.

For installation and tutorials, check out coldtype.goodhertz.com

Here’s a quick example:

from coldtype import *

@renderable((1580, 350))
def render(r):
    return P(
        P(r.inset(10)).outline(10).f(hsl(0.65)),
        StSt("COLDTYPE", Font.ColdtypeObviously()
            , fontSize=250
            , wdth=1
            , tu=-250
            , r=1
            , rotate=15)
            .align(r)
            .fssw(hsl(0.65), 1, 5, 1)
            .translate(0, 5))

Saving that code in a file named test.py and running coldtype test.py (or uv run ct test.py if you’re using uv) results in this image popping up on your screen in a dedicated window:

Check out coldtype.goodhertz.com for instructions on installing and getting started with coldtype.

The best way to get familiar with Coldtype is to look at and try modifying some example code, like the animating gif below. To try out this example and many more, check out the examples/animation directory in this repo.

To get a development environment for Coldtype:

git clone https://github.com/coldtype/coldtype.git
uv sync --extra viewer
uv run ct examples/animations/808.py

To run tests, etc.

uv sync --extra dev

Big thing: match your the Python version in your uv installation (or venv generally-speaking) to the Python version embedded

• Find the desired Blender version:
  • uvx b3denv python --version
• Create a project with that version:
  • uv init --python 3.XX
• Add Coldtype:
  • uv add "coldtype[viewer]"
• Verify Coldtype installation:
  • uv run coldtype demoblender
• Try a Blender-enabled Coldtype file:
  • uv run coldtype demoblender -p b3dlo
