Purpose

Make it easier and quicker to iterate on 4clojure problems and track solutions in Git.

Getting setup

1. Fork this repo.
2. rm -rf problems for a clean slate.

Usage

1. Start up a REPL. E.g. lein repl
2. Execute (load-file "update.clj") on the REPL to populate the problems directory.
3. Edit a problem file to append a solution.
4. Execute (load-file "update.clj") on the REPL to test all the solutions to problems.
5. Repeat at will (from step 3).

Example

Here's an incorrect solution to problem 5:

problems/elementary/05_lists_conj.clj:

; When operating on a list, the conj function will return a new list with one or more items "added" to the front.
; http://www.4clojure.com/problem/5

; (= __ (conj '(2 3 4) 1))
; (= __ (conj '(3 4) 2 1))

(conj [2 3 4] 1)

Running update.clj results in each test case being echoed, along with evaluation of the form containing the substition, and if the test passed:

"(= __ (conj '(2 3 4) 1))"
=> [2 3 4 1]
false

"(= __ (conj '(3 4) 2 1))"
=> [2 3 4 1]
false
