fuzzyd 1.1.1-beta

fuzzyd

A D language fuzzy search library.

The algorithm used is a modified version of Smith–Waterman algorithm. The worst-case performance is O(m*n) for each entry provided in the input. (m and n are the respective length of the tested strings).

About

fuzzyd was primarily created to search matches in a list of files and commands.

Criteria

Score extra points when:

• pattern is found at the beggining of the string.
• pattern is at word boundary position.
• case sensitive matches.

Penalty for:

• isolated matches worth half of the points.

Note: The algorithm examines all the occurrences of the provided pattern, making it slower but more accurate.

Usage

import fuzzyd.core;

string[] source = ["cd Documents"
                  ,"curl localhost/foo"
                  ,"rm -rf Downloads"
                  ,"vi ~/Documents"];

auto fzy = fuzzy(source);

fzy("docts");
/* =>
[FuzzyResult("cd Documents", 1, RedBlackTree([0, 1, 3, 4, 5, 10, 11])),
 FuzzyResult("vi ~/Documents", 0.533052, RedBlackTree([5, 6, 7, 12, 13])),
 FuzzyResult("rm -rf Downloads", 0.33474, RedBlackTree([7, 8, 12, 14, 15])),
 FuzzyResult("curl localhost/foo", 0.292546, RedBlackTree([0, 6, 7, 11, 12, 13, 16, 17]))]
