A basic implementation of Lindenmayer systems in Golang.
This was used to generate L-System trees in my raytracer project lucis. See main.go for the lua code generation based off the L-System.
// Create a new L-System with axiom "S"
system := lsystem.New("S")
// Add basic production rules
system.AddProduction('S', "QX")
system.AddProduction('X', "B[LX[RX]B][RX[LX]B]X")
// Add two production rules with weight 10
// Weights are used as a probability of selecting that rule
// Since both weights are equal, there is a 50% chance for each rule
system.AddWeightedProduction('B', "BB", 10)
system.AddWeightedProduction('B', "B", 10)
// Iterate the system 8 times and print the result
fmt.Println(system.Iterate(8))
