JILT provides a set of utility functions for assisting with the solution of various word based puzzles and problems.
Unless you want to directly work with the code it is recommended that you download the latest release from here.
JILT can perform a variety of functions like solving simple substitution ciphers, finding anagrams, palindromes, tautonyms, and other word curios.
The vampire module can be used to solve a variety of simple
substitution cipher problems, including short examples which are
difficult to solve by hand. Various options are available to show
progress and control how much effort is expended on finding a good
solution. The default model is suitable for English language ciphers.
Example:
> cat cryptogram.txt

CGIASFBDA. FXADA JE SU ASG FU FXA CGIASFBDAE FXCF RA NCS XCIA JL USPK

Often cryptograms will be presented with spaces removed. In that situation it is better to use a corresponding model:
> cat cryptogram.txt
RAPJI AJSCR USGAD LBPRU DPGFX CFJEL BPPUL ZACBF K,NXC DTCSG CGIAS
FBDAF XADAJ ESUAS GFUFX ACGIA SFBDA EFXCF RANCS XCIAJ LUSPK RAEAA

> jilt vampire -q -r 1 --ignore-spaces -m models/nospace.model -i ~/cryptogram.txt
21.098 weliveinawonderfulworldthatisfullofjeautycharmandadventurethereisnoendtotheadventuresthatwecanhaveifonlyweseekthemwithoureyesogenbawaharlalnehru
Note we have used the --ignore-spaces option here because the spaces
in the cryptogram file are not properly a part of the message. Note
also that in this case, the correct solution is not the "best"
solution found.
Similar modules are available for solving Playfair and Vigenere ciphers.
To find anagrams of a word:
> jilt anagram cat
act
cat
There are options available to find multiple word anagrams, override the word list, support unknown letters in the anagram, and so on.
The filter module provides a great many options for selecting words with various properties. In general, a word must pass all the selected filters to be output.
Here we find all the palindromes of length 7 in JILT's standard dictionary:
> jilt dict | jilt filter --palindrome --length 7
deified
hadedah
halalah
reifier
repaper
reviver
rotator
seities
sememes
Currently the support for this kind of problem is not as complete as it could be. In these problems it is assumed that each letter denotes a single digit and each digit is represented by only a particular letter.
All solutions will be printed.
In the following example, there are two equations which much be satisfied.
> jilt equation "EAST + WEST + SOUTH + NORTH = EARTH" "W^N=WHEN"
A = 7, R = 8, S = 2, T = 5, E = 9, U = 3, W = 4, H = 0, N = 6, O = 1.
Note the use of quotes to ensure each equation is seen as a separate parameter.
A word chain problem asks for the shortest sequence of words that can transform one word into another. Options are available to select the exact set of allowed operations.
> jilt chain horse truck
[horse, hoise, poise, prise, price, trice, truce, truck]
The similar ladder module can be used to solve related problems where
the words get shorter or longer by one letter at each step.
The wordsmith module applies a collection of tests in an attempt to
discover an explanation for a sequence of words.
> jilt wordsmith Vienna Brussels Prague Copenhagen Tallinn Helsinki Athens Budapest
All words are cities
All words are capital cities
Associated words are in alphabetical order:
[Austria, Belgium, Czech Republic, Denmark, Estonia, Finland, Greece, Hungary]
> jilt wordsmith NIGHT, PAINTING, INIQUITY, THRIVE, VAPOURS, VERIFY, REVISIT
Increasing Roman numerals:
[I, II, III, IV, V, VI, VII]
Wordle is a popular word game developed in 2022 by Josh Wardle, see here
The player has to guess a five letter word and the responses give clues
as to correct letters and wrong letters. The JILT module wordle can
be used to get suggestions as to what should be played as the next
guesses given the state of any previous guesses.
At the start we have made no guesses, so:
> jilt wordle
Remaining words: 12478
Best: TARES -4.30
The above says in the absence of any information and using the default
dictionary, the best word to guess is TARES. If you have access to the
actual Wordle dictionary, you can specify that instead with -D.
In this example, when we play TARES we get told that A and R are
correct letters but in the wrong positions and that the other letters
do not occur. We use 1 to indicate a correct letter and 0 for a wrong
letter:
> jilt wordle TARES 01100
Remaining words: 240
Best: GRAIL -3.17
We are down to 240 remaining possible words. In our, example we learn
that A is now in correct position, but R is still in the wrong
position, and none of the other new letters occur. So, using 2 to
indicate a correctly placed letter:
> jilt wordle TARES 01100 GRAIL 01200
Remaining words: 24
Best: HOARD -2.28
We play HOARD and discover that ARD is correct and that H also
occurs in the word (which actually means H must be the second letter).
We continue:
> jilt wordle TARES 01100 GRAIL 01200 HOARD 10222
There is a single remaining word CHARD, which is indeed correct.
The wordle module supports other variants of the game where multiple
words are simultaneously solved for (dordle, qordle, etc.) or where
the word length is something other than 5.
There are other modules for finding words in a grid (wordsearch), generating permutations of letters, transforming words in various ways and so on.
Find all words for which after reversing the letters remain a word:
> jilt dict | jilt transform --reverse | jilt filter --in-dict
