mlx

An OCaml syntax dialect which adds JSX expressions to the language.

let header ~title () = 
  <header>
    <h1>title</h1>
  </header>

let page =
  <html>
    <body>
      <header title="Hello, world!" />
      <div>
        "Some content goes here"
      </div>
    </body>
  </html>

This code is transformed into the following OCaml code:

let header ~title () =
  header () ~children:[ h1 () ~children:[ title ] [@JSX]; ] [@JSX]

let page =
  html () ~children:[
    body () ~children:[
      header () ~title:"Hello, world!" [@JSX];
      div () ~children:[ "Some content goes here" ] [@JSX];
    ] [@JSX];
  ] [@JSX]

It is expected to use mlx-pp preprocessor with either a runtime lib which provides the implementation of such functions or a ppx which which further transforms [@JSX] attributes into the desired output.

Installation & Usage

Use the following commands to install the necessary packages:

opam install mlx ocamlmerlin-mlx

To make dune consider .mlx files as OCaml files you need to configure an mlx dialect, put this in your dune-project file:

(dialect
 (name mlx)
 (implementation
  (extension mlx)
  (merlin_reader mlx)
  (preprocess
   (run mlx-pp %{input-file}))))

Editor Support

VS Code

Syntax highlighting support for VS Code is still work in progress. As a temporary workaround, you can enable basic OCaml syntax highlighting by adding this to your settings:

{
  "files.associations": {
    "*.mlx": "ocaml"
  }
}
