val rsplit2 : t -> on:char -> (t * t) option
val split : t -> on:char -> t list
val split_lines : t -> t list
val escape_double_quote : t -> t

Escace ONLY double quotes. escape also escapes '\n',... and transforms all chars above '~' into '\xxx' which is not suitable for UTF-8 strings.

val longest : string list -> int

Return the length of the longest string in the list

val longest_map : 'a list -> f:('a -> string) -> int
val longest_prefix : t list -> t
val exists : t -> f:(char -> bool) -> bool
val for_all : t -> f:(char -> bool) -> bool
val maybe_quoted : t -> t

maybe_quoted s is s if s doesn't need escaping according to OCaml lexing conventions and sprintf "%S" s otherwise.

val enumerate_and : string list -> string

Produces: "x, y and z"

val enumerate_or : string list -> string

Produces: "x, y or z"

val enumerate_one_of : t list -> t

Produces: "One of x, y or z"

val findi : string -> f:(char -> bool) -> int option

Find index of first character satisfying f
