This is a tutorial that explains the implementation of the Game of Life in Clojure. It uses interactive Gorilla-REPL to visualise the key parts of the algorithm.

The original algorithm was published here: http://clj-me.cgrand.net/2011/08/19/conways-game-of-life/ This is just slightly polished version to make it more readable for beginners.

To play with interactive REPL, do the following:

• Make sure you have installed Leiningen
• Clone this repo, download dependencies and run the REPL:

git clone https://github.com/kolman/GoL-Clojure
cd GoL-Clojure
lein deps
lein gorilla :port 8999

• Navigate your browser to http://localhost:8999/worksheet.html?filename=src/joyful_game/worksheet.clj
• Press Ctrl+Shift+Enter to evaluate the whole page.

If you want to add new code segment, press Ctrl-G-N. To evaluate one segment, press Shift-Enter. To see more shortcuts and actions, click on the tree-lines-icon in the top right corner of the page.
