- Synopsis
- Generate art from context-free grammars
- Description
Create art via context free grammar production rules. Includes an SVG backend.
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.
Example
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, at every layer, -- this will have an 85% chance of rendering another circle circles = NonTerminal $ (85, [Move (2, 0)], Circle 1 :| [circles]) :| []- Author
