Wordle Solver

Wanna take all the fun out of the game https://www.powerlanguage.co.uk/wordle/ with a little CLI script?

Run the wordle file in this repo with 2 args per guess: the guess word and guess result

It will output the possible words sorted to include the letters most frequently used in the wordle dictionary.

e.g. one guess:

% ./wordle their xo~~x
Guess word: their
Guess result: xo~~x
7 possible words

chief - 3000
whine - 3063
chime - 3086
chide - 3163
while - 3207
shied - 3355
shine - 3537

7 possible words

e.g. two guesses:

$ ./wordle their xo~~x whine oooxo
Guess word: their
Guess result: xo~~x
7 possible words

Guess word: whine
Guess result: oooxo
1 possible words

while - 3207

If you just wanna know the best first word to try based on letter frequency you can run it without any arguments

% ./wordle
...
irate - 4511
arose - 4534
alter - 4559
alert - 4559
later - 4559

Guess results must be 5 charactes of the form

x = letter miss
o = letter hit in right place
~ = letter hit in wrong place

Need Ruby installed

Note the word list is in the website's javascript, so I've manually extracted that to this repo, but it could get out of date, so uncommenting a single line of code can download a full english dictionary

#five_letter_words = use_full_dictionary

Of course, this is all really a moot point since the answer to every single day is embedded in the javascript code for the website. You can just pull each day's answer out of the browser's localstorage using the browser console

JSON.parse(localStorage.gameState).solution

Or if you wanna see the answer for any given day, you can run a little javascript snippet (de-obfuscated from the original JS)

function solve(solveDate) {
  var anchorDate = new Date(2021,5,19,0,0,0,0),
      dateDiff = solveDate - anchorDate,
      wordIndex = Math.floor(dateDiff / 864e5) % wordList.length;
  return wordList[wordIndex];
}

Just put the word list from this repo into a variable called wordList and run that function, passing in the whatever date you want the solution for
