Checks

val starts_with : prefix:string -> string -> bool
val ends_with : suffix:string -> string -> bool
val contains_char : string -> char -> bool
val contains : sub:string -> string -> bool
val exact_match : Re.re -> string -> bool

Manipulation

val map : (char -> char) -> string -> string
val strip : string -> string
val strip_right : string -> string
val sub_at : int -> string -> string
val remove_prefix : prefix:string -> string -> string
val remove_suffix : suffix:string -> string -> string

Transformations

val cut_at : string -> char -> (string * string) option: Cut a string at the first occurence of the given char

val rcut_at : string -> char -> (string * string) option: Same as cut_at, but starts from the right

val split : string -> char -> string list: Split a string at occurences of a given characters. Empty strings are skipped.

val split_delim : string -> char -> string list: The same as split, but keep empty strings (leading, trailing or between contiguous delimiters)

val fold_left : ('a -> char -> 'a) -> 'a -> string -> 'a
