an ocaml card game engine

An OCaml card game engine that allows users to build their own custom card game and then play it through the terminal

languages and technologies used

• OCaml
• JSON

background

This was the final project for my functional programming course that I built with 3 other group members. We wanted to design an engine that allowed users to write their own card game rules and then play the game. Using a custom card game language to define the rules, users can encode a card game in our engine and then play it.

Using our card game language we have already built some card game config files to use:

• Blackjack
• Crazy Eights
• 5 Card Draw

my role

front-end

• Built the command-line interface and REPL to render the card game and update state accordingly when a player makes a move

back-end

• Helped design the card game language we used to encode rules as strings in JSON card game rule files
• Built the structure used to encode the game state, and helped write update functions for the state
• Designed the lexer and parser for the custom card game rules (encoded strings as abstract syntax trees to be evaluated)
