The concept of Wordle can be found on many websites. Here is an not exhaustive list:

• www.PowerLanguage.co.uk/wordle/ is the official website of Wordle and it alows a play per day.
• www.DailyWordle.com with same interface as PowerLanguage and a word to guess each day.
• HelloWordl.net allow many length words…
• WordleGame.org allow many length words and other languages (english, french, german, spanish) with no limitation on plays.
• wheelsrpgs.itch.io/wheeldle is said to be an infinite Wordle by WheelsRPGs
• sutom.nocle.fr is for french Motus (unaccentued french word of seven letters that starts with the given one and to found within less than six tries.) One play per day.
• motus.absolu-puzzle.com is french Motus too (word of eigh unaccentued letters and seven tries.) No play limitation.
• www.cokogames.com/lingo/play/ five or six letters without limitation
• speellingo.nl Netherland version, three levels with five to seven letters and four time limited rounds.
• www.spel.nl/spel/lingo same interface as SpeelLingo plus age validation.

Tips and history about the game can be found here and there etc. Wordle isn't so new… Motus in France and Lingo in United Kingdom and many other countries predate it. Those games are also available for your desktop operating system or your smartphone. If you enjoy such game, there are some others you may appreciate too except that this script won't be helpful for them.

Either clone the repository:

or just download the script and make it executable:

In both case, ensure the script is in your path (i.e. ~/bin here.)

The script uses three arguments:

1. Well placed letters, e.g BA... after the second try
2. Misplaced letters, e.g ..L.. or A.... after the second or first try
3. The list of letters that don't exist in the word, e.g CRES at first try

When launched without one of the arguments, it swithes to interactively inputing them.

Before starting, prepare your restricted words list, then put it's path into the environment variable WORDLE_LIST prior. Example:

Note that:

• Your words list should be all lowercase… otherwise use -i to make the searches case insentive.
• If this environment variable is empty or unset, the script will go with system global dictionary which also contains names with title-case. That leads to some strange results that cannot be easely fixed.
• You may use -d to display some internal informations before the results.
• Results are often shuffled. Use -s to sort them alphabetically.

By the same way, you can change the number of propositions displayed with the environment variable WORDLE_SHOW. To play some other variant, set the length into the environment variable WORDLE_SIZE and that's all.

Here, with myguess having 8497 entries (but without: bailo, bauld and baulk), the arguments 'ba...' '..l..' 'cresmy' found out:

Have fun.
