Perl developer modules on CPAN

I was just talking about using cpanm to install from github. The latest cpanm also makes it easy to install a developer release. Coincidentally, Ben Bullock just mentioned the developer release of Text::Fuzzy. Let's try it!

$ cpanm --dev Text::Fuzzy
--> Working on Text::Fuzzy
Fetching http://www.cpan.org/authors/id/B/BK/BKB/Text-Fuzzy-0.10_01.tar.gz ... OK
Configuring Text-Fuzzy-0.10_01 ... OK
Building and testing Text-Fuzzy-0.10_01 ... OK
Successfully installed Text-Fuzzy-0.10_01
1 distribution installed

Nice!

Also coincidentally, we were discussing Levenshtein versus Damerau-Levenshtein edit distances just the other day. In particular, it was noted that altitude and latitude were just one transposition away.

#!/usr/bin/env perl

use v5.16;
use warnings;
use Text::Fuzzy;

my $tf = Text::Fuzzy->new("latitude");

say "Levenshtein edit distance is ", $tf->distance("altitude");

$tf->transpositions_ok(1);

say "Damerau-Levenshtein edit distance is ", $tf->distance("altitude");

Lo and behold, the new Text::Fuzzy tells us that!

$ ./fuzzy.pl
Levenshtein edit distance is 2
Damerau-Levenshtein edit distance is 1
