This plugin provides syntax highlight and snippets for Reason.

All other Reason editor functionalities are independently provided by our language server.

Both installations instructions are below.

• Go to Sublime Text -> Preferences -> Browse Packages
• In the terminal, cd into that folder (if you're on macOS, you can click & drag the folder icon into your terminal window)
• git clone https://github.com/reasonml-editor/sublime-reason

The other 90% of Reason's editor experience (intelligent autocompletion, type hint, formatting, jump-to-definition, etc.) is provided by ocaml-language-server (a code analysis backend shared by all editors).

• Install the global binaries.
• Install ocaml-language-server itself through npm install -g ocaml-language-server.
• Install LSP, the sublime text plugin that communicates with ocaml-language-server.

Restart sublime after installing these.

Nothing. Sublime's LSP above has built-in OCaml/Reason support. But you might want to set up some keyboard shorcuts for common actions. See them here. They're exposed as these functions.

Our recommendations:

• Go to Command Palette (cmd-shift-p) -> Preferences: Key Bindings

• Add the following to your configuration:

  [
    // ...whatevever config you had before
    {
      "keys": ["super+alt+enter"],
      "command": "lsp_symbol_definition",
      "context": [
        {
          "key": "selector",
          "operator": "equal",
          "operand": ["source.reason", "source.ocaml"]
        }
      ]
    },
    {
      "keys": ["super+shift+c"],
      "command": "lsp_format_document",
      "context": [
        {
            "key": "selector",
            "operator": "equal",
            "operand": ["source.reason"]
        }
      ]
    }
  ]

  (super means command on macOS) so you can do e.g. cmd-shift-c to format your Reason files.
