trait StringEditDistance extends DiffShortener

The EditDistance trait provides methods to compute and display the shortest distance between 2 strings.

Usage:

showDistance("kitten", "sitting") // returns ("(k)itt(e)n", "(s)itt(i)n(g)")

// with different separators
showDistance("kitten", "sitting", "[]") // returns ("[k]itt[e]n", "[s]itt[i]n[g]")

    sep

    separators used to hightlight differences. If sep is empty, then no separator is used. If sep contains one character, it is taken as the unique separator. If sep contains 2 or more characters, the first half of the characters are taken as opening separator and the second half as closing separator.

    returns

    a (String, String) displaying the differences between each input strings. The used separators are specified by the caller. The string is shortened before and after differences if necessary.
