val hash : string -> int

Hashing on strings. Should be compatible with generic one.

val is_empty : string -> bool

Test whether a string is empty.

val explode : string -> string list

explode "x1...xn" returns ["x1"; ...; "xn"]

val implode : string list -> string

implode [s1; ...; sn] returns s1 ^ ... ^ sn

val drop_simple_quotes : string -> string

Remove the eventual first surrounding simple quotes of a string.

val string_index_from : string -> int -> string -> int

As index_from, but takes a string instead of a char as pattern argument

val string_contains : where:string -> what:string -> bool

As contains, but takes a string instead of a char as pattern argument

val plural : int -> string -> string

plural n s adds a optional 's' to the s when 2 <= n.

val conjugate_verb_to_be : int -> string

conjugate_verb_to_be returns "is" when n=1 and "are" otherwise

val ordinal : int -> string

Generate the ordinal number in English.

val is_sub : string -> string -> int -> bool

is_sub p s off tests whether s contains p at offset off.

val is_prefix : string -> string -> bool

is_prefix p s tests whether p is a prefix of s.
