This directory contains the source code for an Emacs mode that supports working with Coalton code.

Requirements

This mode requires Emacs version > 29.1 because it relies on tree-sitter. You can check that your copy of Emacs was built with support for tree sitter by evaluating:

(treesit-available-p)

Installation

In your emacs init file (probably ~/.emacs.d/init.el or ~/.emacs), add this directory to your load-path, and require the mode:

;; Coalton

(add-to-list 'load-path "~/git/coalton-mode")
(require 'coalton-mode)

Usage

There is an example file, types.coal in the test/ directory.

The first time you open a .coal file, Emacs will ask you to approve the installation of a parser component:

tree-sitter-coalton is not installed. Clone, build and install it?

(Answer 'yes')
