val cut : sep:char -> string -> (string * string) option

cut ~sep s cuts s on the left and right of the first char sep starting from the left.

val rev_cut : sep:char -> string -> (string * string) option

rev_cut ~sep s cuts s on the left and right of the first char sep starting from the right.

val rev_cuts : sep:char -> string -> string list
val starts_with : prefix:string -> string -> bool

starts_with ~prefix s is true iff prefix is a prefix of s. Note. Available in 4.13.

val edit_distance : string -> string -> int

edit_distance s0 s1 is the number of single character edits (insertion, deletion, substitution) that are needed to change s0 into s1.

val suggest : ?dist:int -> string list -> string -> string list

suggest ~dist candidates s are the elements of candidates whose edit distance is the smallest to s and at most at a distance of dist of s (defaults to 2). If multiple results are returned the order of candidates is preserved.
