boggler's Introduction

Boggler

A solver for the popular word game Boggle.

Install

pip install boggler

Setup

To use the script to solve a Boggle board, you'll need to do a few things first.

  1. Create .csv of the board state like so:

    Here is an example board.csv. Note the orientation of the board does not matter.

    $ cat board.csv
y,e,o,s
r,e,o,v
d,f,e,y
n,m,e,qu

  2. Find or create a dictionary wordlist file

    The dictionary wordlist should have each word on a single line like so

    $ cat wordlists/wordlist.txt
a
aa
aaa
aah
aahed
aahing
aahs
aal
...
zwiebacks
zwieselite
zwinglian
zwinglianism
zwinglianist
zwitter
zwitterion
zwitterionic

  3. Split the dictionary wordlist into separate files based on the first letter of each word.

    To split an English wordlist, use the split_wordlist_alpha.sh script like so:

    $ split_wordlist_alpha.sh my_wordlist.txt .

    This will generate a series of sub-dictionaries for each letter in the alphabet in the current directory.

    $ ls
my_wordlist.txt  words_d.txt  words_h.txt  words_l.txt  words_p.txt  words_t.txt  words_x.txt
words_a.txt      words_e.txt  words_i.txt  words_m.txt  words_q.txt  words_u.txt  words_y.txt
words_b.txt      words_f.txt  words_j.txt  words_n.txt  words_r.txt  words_v.txt  words_z.txt
words_c.txt      words_g.txt  words_k.txt  words_o.txt  words_s.txt  words_w.txt

Usage

CLI usage

 
$ poetry run boggler --help
usage: boggler [-h] [-f FORMAT] [-p] [-s] [-d] board wordlists [max_word_length]

Boggle board game solver


positional arguments:
board                 Path to board CSV file
wordlists             Path to directory of wordlist files. The directory must contain text files of the form words_X.txt where "X" is a character of the
alphabet
max_word_length       Maximum length of words searched for on provided board


options:
-h, --help            show this help message and exit
-f FORMAT, --format FORMAT
Specify alternative output format including [txt, json]
-p, --include-path    Include full paths for each word in output
-s, --sort            Sort output alphabetically. By default the results are sorted by the starting block position on the board from top-to-bottom, left-
to-right as given in the board file.
-d, --dedup           Remove duplicates from word-only output. Note that de-duplication does not preserve the original order of the output, so it is
recommended to also use the sort option when de-duplicating.

Example board solve

 
$ poetry run boggler ./boggler/boards/b1.csv boggler/wordlists/scrabble_2019/
