Tablecloth

A portable standard library enhancement for Reason and OCaml.

Tablecloth provides an easy-to-use, comprehensive and safe standard library that has the same API for the OCaml and Bucklescript compilers.

open Tablecloth;
String.toList("Tablecloth")
|> List.filterMap(~f=character => 
  Char.toCode(character)
  |> Int.add(1)
  |> Char.fromCode
)
|> String.fromList
/* "Ubcmfdmpui" */

Easy to learn

Excellent documentation, comprehensive examples and consistent behaviour make Tablecloth efficient to get started with

Safe

Banish runtime errors and work effectively with Options and Results
reason
let name = Some("Kubo");
let species = Some("dog");
let favoriteGame = None;
let bio = Option.({
  let (name, species) = Option.both(name, species);
  name ++ " the " ++ "'s favorite game is" ++ (favoriteGame |? "fetch");
})

Portable

Works with either the Reason or OCaml syntax, targeting the Bucklescript, Native or js_of_ocaml compilers

Advanced

Index operators for Arrays, Maps, Sets and Strings plus binding operators for Options & Results mean your code is concise and expressive
ocaml
let nameToSpecies = Map.String.fromList [
  ("Amy", "Ant");
  ("Barry", "Badger");
]
(* Get a value from a Map by its key *)                     
nameToSpecies.Map.?{"Carolyn"} = None
  
(* Extract a Char from a String safely *)
"Tablecloth".String.?[1] = Some('a')
(* Index into an Array without fear *)
[|2;3;5;7|].Array.?(3) = Some(7)
