String (loko.Loko.String)

val ends_with : 
  Stdlib.String.t ->
  ( Stdlib.String.t, Stdlib.String.t, Stdlib.String.t, Stdlib.String.t ) optic

A prism that focuses on the prefix of a string that ends with the given suffix.

val escaped : 
  ( Stdlib.String.t, Stdlib.String.t, Stdlib.String.t, Stdlib.String.t ) optic

An isomorphism that escapes on read and unescapes on write.

let "'\\t' vs ' '" = L.view L.String.escaped "'\t' vs ' '"

val split_on_char : 
  char ->
  ( Stdlib.String.t,
    Stdlib.String.t list,
    Stdlib.String.t list,
    Stdlib.String.t )
    optic

An isomorphism between separated string and list of strings.

let "One:Two:Three" =
  L.over (L.String.split_on_char ':' ^<< L.List.elems)
    String.capitalize_ascii
    "one:two:three"

val starts_with : 
  Stdlib.String.t ->
  ( Stdlib.String.t, Stdlib.String.t, Stdlib.String.t, Stdlib.String.t ) optic

A prism that focuses on the suffix of a string that starts with the given prefix.

val sub : 
  int ->
  int ->
  ( Stdlib.String.t, Stdlib.String.t, Stdlib.String.t, Stdlib.String.t ) optic

sub pos len is a lens that focuses on the substring that starts at specified position and has given length.

let "Loko" = L.set (L.String.sub 1 3) "ok" "Lasso"

val trim : 
  ( Stdlib.String.t, Stdlib.String.t, Stdlib.String.t, Stdlib.String.t ) optic

An isomorphism that trims the string in both directions.

val unescaped : 
  ( Stdlib.String.t, Stdlib.String.t, Stdlib.String.t, Stdlib.String.t ) optic

An isomorphism that unescapes on read and escapes on write.
