cellular automata generator (in Go)

More documentation about Automata and their implementation on eliseduverdier.github.io/cellular-automata-go/.

Generates elementary cellular automata images, with 2 to 9 states, or 1st and 2nd order, with customizable size, colors, and points distribution, using Go

• As PNG images (rule 73)

  

• Or as text (rule 110)

Use locally

PORT=8888 go run main.go

Then go to http://localhost:8888/text or http://localhost:8888/image and use GET parameters (listed below)

Exemple of nice automatas

parameters

option	role
s	number of states (>2)
o	order (1 or 2)
r	rule number
w	width in pixels
h	height in pixels
p	size of one cell in pixels (1 < p < 20)
start	first line strategy ("random", "centered", "left", "right", see below)
line	a sequence of numbers representing the first line like "0000010..."

Run tests

# run tests
make test
# generate code coverage
make coverage
# lint (needs https://golangci-lint.run/)
make lint

Etc

Todo

• add docker
• add option to get dots bigger than 1px
• add option to choose custom colors
• Cache when rule isn't random
