I'm working through Jamis Buck's Mazes for Programmers.
I'm a Clojure newb, so this is not likely to be fantastic code.
Fire up your REPL:
$ lein repl
To print a 3-by-3 grid with no links between any cells:
mazes.core=> (require '[mazes.repr.ascii :refer [print-grid]])
mazes.core=> (require '[mazes.grids.rectangular :refer [make-grid]])
mazes.core=> (print-grid (make-grid 3 3))
That'll give you something like this:
+---+---+---+
| | | |
+---+---+---+
| | | |
+---+---+---+
| | | |
+---+---+---+
To generate a maze using the Recursive Backtracker algorithm on a 5-by-10 grid:
mazes.core=> (require '[mazes.alg.recursive-backtracker :as rec-back])
mazes.core=> (print-grid (rec-back/on (make-grid 5 10)))
That'll give you something slightly (but only slightly) more impressive:
+---+---+---+---+---+---+---+---+---+---+
| | | | |
+ + + + + +---+---+ +---+ +
| | | | | | | | |
+ + + + +---+ + +---+ + +
| | | | | | |
+ + +---+---+ +---+---+ + +---+
| | | | | |
+ +---+ +---+---+ +---+---+---+ +
| | |
+---+---+---+---+---+---+---+---+---+---+
If you want bigger, better-looking mazes with pretty colors, load up the Web frontend:
$ lein ring server 4000
(Or, to hack on it, boot up figwheel.)
$ rlwrap lein figwheel
