NAME#

Text::Sift4 - A Perl 6 Sift4 (Super Fast and Accurate string distance algorithm) implementation

SYNOPSIS#

use Text::Sift4;

say sift4("abc", "ab");  # OUTPUT: «1␤»
say sift4("ab", "abc");  # OUTPUT: «1␤»
say sift4("abc", "xxx"); # OUTPUT: «3␤»

DESCRIPTION#

Text::Sift4 is a Perl 6 Sift4 implementation. Sift4 computes approximate results of Levenshtein Distance.

METHODS#

sift4#

Defined as:

sub sift4(Str $lhs, Str $rhs, Int :$max-offset = 5 --> Int:D) is export

returns approximation of Levenshtein Distance.

• Str $lhs is one side of the strings to compare.

• Str $rhs is one side of the strings to compare.

• Int :$max-offset is the maximum offset value. The value is default to 5.
