Headless utilities for graphics programming in Python, meant for use in graphics programming environments like Coldtype, DrawBot, Blender, or hardware drawing machines like AxiDraw.

• Geometric primitives (drafting/geometry) for slicing & dicing rectangles (CGGeometry-inspired)
• Color primitives for easy color manipulation (drafting/color)
• Fluent-programming RecordingPen subclass (drafting/pens) with common pen operations & a DrawBot variant (drafting/pens/drawbotpen)
• Line-oriented text-setting primitives, based on HarfBuzz-via-FontGoggles (drafting/text/reader)
• DrawBot-specific integration shortcuts (drafting/drawbot)
• Symbolic shorthand language for vector-drawing-from-code (APL-inspired) (drafting/sh)

All-in-all, a mess of bizarre features inspired by a mess of bizarre influences, but features that I use regularly via Coldtype, which is currently being refactored to use this library as a directy dependency.

An example? Sure here's an example:

import drafting.drawbot as dr
from drafting.text.richtext import RichText

f1 = dr.Font.Cacheable("~/Type/fonts/fonts/ObviouslyVariable.ttf")
r = dr.page_rect()

rt = (RichText(r,
        "DRAF[high]/TING", {
        "default": dr.Style(f1, 200,
            wght=0.25,
            wdth=0.15,
            slnt=1,
            fill=dr.bw(0.2)),
        "high": dr.Style(f1, 250,
            ro=1,
            wdth=0.25,
            wght=1,
            tu=-50, # tracking-in-units
            fill=dr.hsl(0.9, 0.9, 0.8),
            stroke=dr.hsl(0.55, 0.9, 0.4),
            strokeWidth=5)},
        invisible_boundaries="/")
    .xa() # center each line
    .align(r)
    .chain(dr.dbdraw))

All formerly part of Coldtype, but broken out into an independent library for easier integration in programs like DrawBot and (in the future) Blender.
