context-free-art: Generate art from context-free grammars
Create art via context free grammar production rules.
Context free grammar primer
Context free grammars consist of a set of terminal symbols, a set of non-terminal symbols, and production rules that map non-terminals to other symbols.
With a context-free grammar, we can generate strings of terminals that conform to the specified language.
Our language will describe graphics.
import Art.ContextFree import Data.List.NonEmpty -- Let's define a Production rule a = Circle 1 -- This will produce an IO Svg from the blaze-svg package -- to turn it into a string we can use one of the `blaze-svg` renderers graphic1 = interpret $ Circle 1 -- let's create a non-terminal, 'a', which renders a terminal, 'Circle 1' -- and has an 85% chance of rendering itself, placed to its right a = NonTerminal $ (100, Circle 1) :| [(85, b)] b = Mod [Move (2, 0)] a
