dewordle

Shell script for assisting in solving the Wordle quiz [1].

It was created out of curiosity how such tool may look like. No guarantees. It may either help or reduce satisfaction. Use at your own risk ;-)

Usage

Usage: ./dewordle.sh POSITIONS [ALPHABET [LETTERS]]

POSITIONS -- pattern of letters with positions we are sure
ALPHABET -- set of possible letters to check; default is: a-z
LETTERS -- confirmed letters, with unknown positions; default empty

NOTE: For POSITION, a regular expression is expected with dots (.)
      representing any character; for first run just try: .....

NOTE: For ALPHABET, a negative set can be given, e.g. ^abc means
      that none of letters a, b or c should be part of the string.

Example

Find a word that has o as second letter and l as fourth letter, containing letters a and g at some positions, but for sure no p, q and r anywhere.

./dewordle.sh .o.l. ^pqr ag

Using own dictionary

By default, the script looks for ~/.dewordle-words file in system.

If this file is not present, it downloads the example file from [2].

Alternatively, one may use their own dictionary file. The expected format should match standard Unix words file [3], i.e. one word in each line.

Having the wordlist or words package installed, the following symbolic link should work:

ln -s /usr/share/dict/words ~/.dewordle-words
