String::KeyboardDistanceXS - String Comparison Algorithm
use String::KeyboardDistanceXS qw( :all ); my $s1 = 'Apple'; my $s2 = 'Wople'; # compute a match probability my $pr = qwertyKeyboardDistanceMatch($s1,$s2); # find the keyboard distance between two strings my $dst = qwertyKeyboardDistance('IBM','HAL');
This is an XS implementation of the main qwerty functions for computing the distance and match probabilities from the String::KeyboardDistance module. Please see the documentation for String::KeyboardDistance for more about these functions.
Since these functions are implemented as XS, in C, they are significantly faster than the Perl based functions in String::KeyboardDistance. That is the primary reason for this module, performance.
This module only implements 2 of the functions from the Perl based module. We should match the API from the other module as well as possible. Some of the features will not be possible with this module, namely making the keyboard maps easily accessable to Perl code.
None by default. Functions are exported with the :all tag.
