Example for MutatorMath in Drawbot. It shows how to make math objects for a color and a shape and how to process them with MutatorMath.

Assuming you have
a UFO open in RoboFont
a current glyph selected

Deprecated list of glyph constructions.

# Glyphname: BaseGlyph Accent.RelativePosition* Accent.RelativePosition*
# *RelativePosition can be top, bottom, left, right

# NOTE: this is not a comprehensive, or even accurate, glyph list.

RoboFont: switch edit windows: edit window for the current glyph, but the from the next master.
"""
If you're editing masters or whatever
and you want to switch to the same glyph in the other master
and you spend a lot of time moving glyph windows around
Add this script to RF and wire it to a key command

LettError / spaceFolder.py
Created November 10, 2017 09:41
Example of how to use a mutatorMath designspace to transform n-dimensional Location objects from one point in space to another. AFAICT this is how the XVAR transformations would work.
from mutatorMath.objects.mutator import buildMutator, Location
# "That is, travel to any part of the Universe without moving."
# This is a demo of how to warp locations in a n-dimensional space.
# The mutatorMath Location object is a more or less a basoc python dictionary.
# But it can also behave as a math object, and that makes it possible
# to calculate xvar like transformations. In this example Location objects
# are both used to place an object in a designspace, as well as the objects themselves.
