Games::Word - utility functions for writing word games
use Games::Word; print "permutation!\n" if is_permutation 'word', 'orwd'; my $mm_solution = random_string_from "abcdefgh"; my $mm_guess = <>; chomp $mm_guess; my $mm_correct_letters = shared_letters $mm_solution, $mm_guess; my $mm_correct_positions = shared_letters_by_position $mm_solution, $mm_guess;
Games::Word provides several utility functions for writing word games, such as manipulating permutations of strings, testing for similarity of strings, and finding strings from a given source of characters.
- random_permutation STRING
Returns a string which is a random permutation of the letters in STRING.
- is_permutation STRING1, STRING2
Returns true of STRING1 is a permutation of STRING2, and false otherwise.
- all_permutations STRING
Returns a list containing all permutations of the characters in STRING.
Returns a list of the characters that STRING1 and STRING2 have in common, ignoring their position in the string.
In list context, returns a list that is the length of the larger of STRING1 and STRING2, which contains the character at that position in both strings if they are the same, and undef otherwise.
In scalar context, returns the number of characters that are the same in both value and position between STRING1 and STRING2.
- random_string_from STRING LENGTH
Uses STRING as an alphabet to generate a random string of length LENGTH. Characters in STRING may be repeated.
- is_substring SUBSTRING STRING
Returns true if SUBSTRING consists of only characters from STRING, in order. For example, 'word' is a substring of 'awobbrcd', but not of 'dcrbbowa' or 'awbbrcd'.
- all_substrings STRING
Returns a list of all substrings (see is_substring) of STRING.
- is_subpermutation SUBSTRING STRING
Returns true if SUBSTRING is a subpermutation (like is_substring, but without caring about order) of STRING, and false otherwise.
- all_subpermutations STRING
