Filters a list based on a fuzzy string search.

Fuzzily is a library that filters a list based on a fuzzy string search. Uses TextualMonoid to be able to run on different types of strings.

Fuzzily

Fuzzy string search library in Haskell. Uses TextualMonoid from monoid-subclasses to be able to run on different types of strings.

This is a fork of Joomy Korkut's fuzzy, which itselft was a port of the JavaScript library mattyork/fuzzy.

It's main difference is more readable code and a cleaner API:

• Descriptive variable names
• ADTs instead of booleans
• …

It was initially forked to be used in TaskLite's find sub-command.

Usage

> import Text.Fuzzily

> match HandleCase ("", "") id "fnt" "infinite"
Just (Fuzzy
        { original = "infinite"
        , rendered = "infinite"
        , score = 3
        })

> match IgnoreCase ("<", ">") fst "hsk" ("Haskell", 1995)
Just (Fuzzy
        { original = ("Haskell", 1995)
        , rendered = "<H>a<s><k>ell"
        , score = 5
        })

> langs = [("Standard ML", 1990), ("OCaml", 1996), ("Scala", 2003)]
> filter IgnoreCase ("<", ">") fst "ML" langs
[ Fuzzy
    { original = ("Standard ML", 1990)
    , rendered = "Standard <M><L>"
    , score = 4
    }
, Fuzzy
    { original = ("OCaml", 1996)
    , rendered = "OCa<m><l>"
    , score = 4
    }
]

> simpleFilter "vm" ["vim", "emacs", "virtual machine"]
["vim", "virtual machine"]
