A minimal CLI text editor, built on Ruby, looking for Emacs as it's father and idol.

As developing packages for Emacs with Elisp wasn't always a fun or easy task, Starting a project that leverage ruby ability for fast development will be a good move towards an open, easy to extend editor.

When I started this project I had 2 options, taking the VIM way or emacs way, looking in the current state of the two editors, It's obvious that emacs approach has a better extensibility over VIM, emacs customizability is far superior to VIM, so building this project as a minimal and emacs-like would open the door for vim users to have their own bindings as a package like emacs Evil mode, but doing the other way around won't help emacs users.

Advantages of building an editor in ruby

  • We can use ruby gems as package management
  • we already have bundler to fix dependencies, upgrade, downgrade gems (plugins in this case), you can even add sources for gems or get a gem from github or company inhouse gems.
  • you can reflect on the runtime and autocomplete commands
  • plugins can mutate all parts of the runtime application classes/objects included
  • ruby is easy to learn so it'll be easier to build gems that is specifically for this editor
  • lots of gems already exists and could be loaded into the editor environment
  • you can use it locally or remotly as it's terminal based
  • documentation included, rdoc is already there to be used

Installation

$ gem install amun

Usage

amun install an executable to your path, so executing amun from your command-line should launch amun

Structure

Helpers

Helpers are modules that any class can use to do side tasks, think of it like Ruby on rails helpers.

  • Only modules no classes
  • doesn't depend on each other
  • depends on the project dependencies only like "Curses"

MajorModes

Classes that are responsible the following for a buffer object:

  • event handling
  • manipulating IO
  • Rendering IO into a curses window

Development

After checking out the repo, run bundle install to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
