snowFall Program

By Meagan Olsen, Kevin Deming, and Alex Bailey

Implement semantics of MiniMiniLogo Language that generates a drawn picture.

Instructions

1. Install haskell platform
   
2. Open terminal
   
3. cd <your directory>
   
4. ghci
   
5. :l (name of file(no extensions))

Dicussion

We used a Haskell implementation of MiniMiniLogo, a derviative of the the Logo language and Haskell to create this app.

Requirements

prog 	::= 	ε   |   cmd ; prog 	sequence of commands
mode 	::= 	down   |   up 	pen status
cmd 	::= 	pen mode 	change pen mode
	| 	move ( int , int ) 	move pen to a new position

• implements a change in the state of the pen
• implements a list of lines to draw
• implement ```cmd```, the semantic function for MiniMiniLogo commands (Cmd)
• Implement prog, the semantic function for MiniMiniLogo programs (Prog).
