wordleist

A Clojure library designed to generate and solve wordle-style puzzles.

Status

This works reasonably well. It doesn't have a client interface to the real Wordle server; that coulf be done but it wasn't my objective.

It solves 94% of wordles in random tests in 6 or fewer attempts; the distribution of attempts in testing is:

wordleist.core=> (frequencies (map :attempts s))
{1 1, 
2 37, 
3 30, 
nil 6, ;; these are the failures
4 18, 
5 6, 
6 2}

Usage

Core functions

• (wordle target guess): given this target as the word sought, return the wordle pattern for this guess.
• (wordle-gen): return a new wordle function, whose target is a word chosen at random from the word list.
• (consistent? pattern target): Where pattern is a pattern as returned by wordle, and target is a string representing a five letter word, return true it target is consistent with pattern, else false.
• (solve game): Solves a wordle game, and returns the solution.

Example:

wordleist.core=> (pprint (solve (wordle-gen)))
{:word "young",
 :attempts 5,
 :patterns
 (([:not-present \s]
   [:not-present \e]
   [:not-present \a]
   [:present \o]
   [:not-present \r])
  ([:not-present \w]
   [:found \o]
   [:found \u]
   [:not-present \l]
   [:not-present \d])
  ([:not-present \c]
   [:found \o]
   [:found \u]
   [:not-present \l]
   [:not-present \d])
  ([:not-present \f]
   [:found \o]
   [:found \u]
   [:found \n]
   [:not-present \d])
  ([:found \y] [:found \o] [:found \u] [:found \n] [:found \g]))}
