Text::...au::PP(3pm)

💖 NAME 💖

Text::Levenshtein::Damerau::PP — bestie, it's the Pure Perl Damerau Levenshtein edit distance. That's it, that's the whole vibe. 👑

---

✨ SYNOPSIS ✨

use Text::Levenshtein::Damerau::PP qw/pp_edistance/;

print pp_edistance('Neil','Niel');
# prints 1

okay so lowkey iconic that 'Neil' and 'Niel' are one whole transposition apart and this module knows. 💅

---

🌸 DESCRIPTION 🌸

It returns the true Damerau Levenshtein edit distance of strings, adjacent transpositions included. It's the Pure Perl implementation, and it works correctly with utf8. No cap. 🦋

use Text::Levenshtein::Damerau::PP qw/pp_edistance/;
use utf8;

pp_edistance('ⓕⓞⓤⓡ','ⓕⓤⓞⓡ'),
# prints 1

she handles the pretty circled unicode letters too, we love that for her 💜

🎀 METHODS 🎀

🍓 pp_edistance

The way this one is the whole function. Arguments: a source string and a target string. 🫶

• OPTIONAL 3rd argument int (max distance; only return results with $int distance or less). 0 = unlimited. Default = 0.

Returns: an int that represents the edit distance between the two argument. It stops calculations and returns -1 if max distance is set and reached. 💀

Function to take the edit distance between a source and target string. Contains the actual algorithm implementation. main character energy fr fr. ✨

use Text::Levenshtein::Damerau::PP qw/pp_edistance/;
print pp_edistance('Neil','Niel');
# prints 1

print pp_edistance('Neil','Nielx',1);
# prints -1

see how that second one bails out with -1? that's the max-distance cap doing its thing, not a bug, bestie 😌
