Roy mode is a tiny major mode for emacs. It can be used for editing roy scripts.
This is the easiest solution, once installed you don't have anything to add to your emacs config, just open a roy file and you are good to go.
It can be more convenient to use Emacs's package manager to handle
installation for you if you use many elisp libraries. If you have
package.el but haven't added Marmalade or MELPA, the community package source,
yet, add this to your .emacs :
Using Marmalade:
(require 'package)
(add-to-list 'package-archives
'("marmalade" . "http://marmalade-repo.org/packages/"))
(package-initialize)Using MELPA:
(require 'package)
(add-to-list 'package-archives
'("melpa" . "https://melpa.org/packages/") t)
(package-initialize)Then do this to load the package listing:
- M-x eval-buffer
- M-x package-refresh-contents
If you use a version of Emacs prior to 24 that doesn't include package.el, you can get it from http://bit.ly/pkg-el23.
If you have an older ELPA package.el installed from tromey.com, you should upgrade in order to support installation from multiple sources. The ELPA archive is deprecated and no longer accepting new packages, so the version there (1.7.1) is very outdated.
From there you can install roy-mode or any other modes by choosing them from a list:
- M-x package-list-packages
Now, to install packages, move your cursor to them and press i. This will mark the packages for installation. When you're done with marking, press x, and ELPA will install the packages for you (under ~/.emacs.d/elpa/).
- or using M-x package-install roy-mode
Roy-mode is based on generic-mode, so it needs to be installed.
To install roy-mode, just add (require 'roy-mode) to your .emacs file.
You can start REPL by executing M-x roy-repl. If you're getting unwanted escape characters in your repl (something like [1Groy> �[0K�[6G instead of roy>), add export NODE_NO_READLINE=1 to your .bashrc config.
- Add a way to compile to javascript or run file from editor
- Support indentation
