Usage

godice.compareString(a, b str) float64

Compare string a to string b and return the score.

godice.CompareString("gopher", "golang") 

The above would return 0.2.

Strings are converted to lowercase

godice.compareStrings(a str, b []str) Matches

Compare string a to a slice of strings. Strings are sorted by their score.

godice.CompareStrings("golang", []string{"gopher", "gerbil", "grison"})

The above would return:

Matches{
  BestMatch:{ Text: "gopher", Score: 0.2 },
  Candidates:[
    { Text: "gopher", Score: 0.2 },
    { Text: "gerbil", Score: 0.0 },
    { Text: "grison", Score: 0.0 },
  ],
