Welcome crepe6,

Please always include the output from uname -a wrapped in CODE tags so we know which OS and version you are using.

Please confirm the context of this issue, i.e. is it homework/course assignment so we know how to answer.


If you are looking for 3 or more of the same character in succession (given that double-letters are valid in many words) would you be okay with some Perl?

An expression something like /(.)\1\1/ might help I think, i.e. match any character followed by the same twice. You might want to refine that to letters only to avoid matching on white-space or numbers if they are in your file too.


Of course, this doesn't match kraark, tattarrattat, wibblewobblesnoozydunno or even Hh_ee_ll_ll_oo_WW_oo_rr_ll_dd if they are in (or added to) the list, so should they be in or out?

Is there a dictionary list you can match against if you want real words only?


You need to be clearer to your criteria, after answering if this is homework or if not giving the context so we can most suitably be able to progress this.



Kind regards,
Robin

BOGGLE(6)							 BSD Games Manual							 BOGGLE(6)

NAME

     boggle -- word search game

SYNOPSIS

     boggle [-bd] [-s seed] [-t time] [-w length] [+ [+]] [boardspec]

DESCRIPTION

     The object of boggle is to find as many words as possible on the Boggle board within the three minute time limit.	A Boggle board is a four
     by four arrangement of Boggle cubes, each side of each cube displaying a letter of the alphabet or `qu'.  Words are formed by finding a
     sequence of cubes (letters) that are in the game's dictionary.  The (N+1)th cube in the word must be horizontally, vertically, or diagonally
     adjacent to the Nth cube.	Cubes cannot be reused.  Words consist solely of lower case letters and must be at least 3 letters long.

     Command line flags can be given to change the rules of the game.

     -b 	Run boggle in batch mode.  A boardspec must also be given.  The dictionary is read from stdin and a list of words appearing in
		boardspec is printed to stdout.

     -d 	Enable debugging output.

     -s seed	Specify a seed seed other than the time of day.

     -t time	Set the time limit for each game from the default 3 minutes to time seconds.

     -w length	Change the minimum word length from 3 letters to length.

     +		This flag allows a cube to be used multiple times, but not in succession.

     ++ 	This flag allows the same cubes to be considered adjacent to itself.

     boardspec	A starting board position can be specified on the command line by listing the board left to right and top to bottom.

     Help is available during play by typing '?'.  More detailed information on the game is given there.

BUGS

     If there are a great many words in the cube the final display of the words may scroll off of the screen.  (On a 25 line screen about 130
     words can be displayed.)

     No word can contain a 'q' that is not immediately followed by a 'u'.

     When using the + or ++ options the display of words found in the board doesn't indicate reused cubes.
