These utilities help to solve gurgle puzzles. STRATEGY 1. Figure out what letters you need 2. Guess the word WHAT YOU NEED two files: * solutions.txt * guessable.txt (a basic 5-letter-word list will suffice for both) posix-compatible programs: * sh * grep * wc * cat * tr * test * echo * sort * uniq * awk UTILITIES * has.sh: filter program for the correct letter in an incorrect position. Called by gurg.sh * gurg.sh: creates multiple filters for a guess in Guess Syntax * whatToDo.sh: Gives advice on whether to guess the word, or guess unguessed letters. Has optional threshold parameter. GUESS SYNTAX guess G.esS you guessed the word `guess`, and * the G was in the correct position * the U was not present * the E was in the incorrect position * the fourth s was in the incorrect position * the fifth S was in the correct position. EXAMPLE ```sh cat solutions.txt | ./whatToDo.sh guessable.txt # Outputs the Letter Frequency, # and words that contain the Most Frequent letters. cat solutions.txt | ./gurg.sh guess ..e.S | ./whatToDo.sh guessable.txt # Outputs LF and words that contain MF *unguessed* letters. cat solutions.txt |./gurg.sh guess ..e.S | ./gurg.sh ratio .at.. |./whatToDo.sh guessable.txt # Outputs a list of Possible Solutions cat solutions.txt |./gurg.sh guess ..e.S | ./gurg.sh ratio .at.. |./whatToDo.sh guessable.txt 5 # Outputs LF ``` CAVEATS Currently only supports 5-letter puzzles using ascii characters. Patches welcome.
