If you love GNU/Emacs, If you love to program in an editor instead of big slow IDE but still enjoy to have a handy code editor then FG42 is the right choice for you.

If you need help, or even want to just say hello, try our IRC channel on freenode: #5hit.

Dependencies

In order to run FG42 you need GNU Emacs >= 25. FG42 uses several extensions internally which each of the has different external dependencies. To gain more information about external dependencies ( If we failed to tell you inside the FG42 ) just run the describe-extension command.

Installation

In order to install FG42, issue the following commands:

# clonse the FG42 repository in ~/.fg42 directory
$ git clone git://github.com/FG42/FG42.git ~/.fg42/
# You can clone it where ever your want
$ cd ~/.fg42/
$ make install

Since the installer script uses sudo, during the installation process, you’ll have to enter your password. Make sure that you’re user account has a sudo access.

If you suffer from poor internet connection (like people in my homeland), you can also download the tarball from release section and extract the tarball in your $HOME directory. So you’re going to end up with .fg42 directory in your $HOME and all you have to do is to install it using make install command.

NOTE: Please note that the tarball releases are still experimental and might have some issues since they contain the elisp packages as well. In case of any problem please report the issue.

Enjoy using FG42 ;)

Configuration

After installation there would be a file at ~/.fg42.el which is the user specific configuration of FG42. You can configure your copy of FG42 using this file. Also you can generally use this file to configure Emacs as well.

Terms & Concepts

FG42 introduced some new features to the Vanilla Gnu/Emacs. So you migh encounter several of these features during your journey. It’s a good idea to at least know what you’re dealing with.

Extensions

FG42 created around the idea of extensions. Each extension extends the FG42 functionality for a certain language or use case. For example clojure extension adds support for a integrated development environment for clojure language. All the configuration related to this environment leave inside that extension. By default, all the extensions which ships with FG42 are enabled. In order to disable any extension which you might not need, just comment them out in your user configuration file in ~/.fg42.el. For example here is my own list:

(activate-extensions 'editor
                     'development
                     'web
                     'editor-theme
                     'javascript
                     ;;'ruby
                     'clojure
                     ;;'php
                     'python)
                     ;;'arduino

In order to learn more about each extension you can use M-x describe-extension.

Abilities

Abilities are the smallest piece of configuration which add support for a certain functionality to FG42. Each extension contains several abilities. Using abilities you can choose the set of abilities you like and disable those which you don’t like. For example helm and ido are two different library which conflicts with each other by we have an ability for each of them in the system, so you can choose which one to use and disable the other one.

In order to disable any ability, just add them to your configuration file in ~/.fg42.el. For example my current disabled abilities are:

(disable 'rbenv-global 'helm 'spell 'linum  'ivy 'smart-mode-line 'desktop-mode)

In the above list I disabled helm because I want to use ido. At the moment there is no way to find out about all the enabled abilities at runtime. Or discover what abilities present in any extension (You can take a look at extension docs using describe-extension command) at runtime. But I’ll add something later :P.

Documentation

If you’re familiar with GNU/Emacs you’re not going to have a problem with getting help. But just to clrearify here is a list of keybindings that may guide you during your experience:

Key bindings command Description
C-? cheatsheet-show Quick cheatsheet
  describe-extension It’s going to ask you an extension name and show you the documentation of that extension
C-h m describe-mode All the information and keybindings of your current modes. e.g open of a ruby file and use the this keybinding to take a look at all the keybinding of ruby extension

what’s with the name?

I’m a huge fan of Steins Gate anime and I follow its naming convensions on Future Gadgets 42.

Why we moved from Github ?

We’re not happy with Microsoft buying Github and we don’t trust a company like Microsoft because of their history and their strategies (For more information take a look at (Halloween documents). So we decided to move to Gitlab as an alternative and we are happy here so far.
