syl20bnr 74fdbb6795 Refactor and simplify company backends declaration
Enabling a company backend for a specific mode was a tedious tasks with code
scattered at different locations, one for local variable definitions, one for
company hook function definitions and another where the backends were pushed to
the local variables (which was problematic, since we ended up pushing the same
backends over and over again with `SPC f e R`, pushes have been replaced by
add-to-list calls in the new macro).

All these steps are now put together at one place with the new macro
spacemacs|add-company-backends, check its docstring for more info on its
arguments.

This macro also allows to define arbitrary buffer local variables to tune
company for specific modes (similar to layer variables via a keyword :variables)

The code related to company backends management has been moved to the
auto-completion layer in the funcs.el file. A nice side effect of this move is
that it enforces correct encapsulation of company backends related code. We can
now easily detect if there is some configuration leakage when the
auto-completion layer is not used. But we loose macro expansion at file loading
time (not sue it is a big concern though).

The function spacemacs|enable-auto-complete was never used so it has been
deleted which led to the deletion of the now empty file core-auto-completion.el.

The example in LAYERS.org regarding auto-completion is now out of date and has
been deleted. An example to setup auto-completion is provided in the README.org
file of the auto-completion layer.

RCIRC layer

/TakeV/spacemacs/media/commit/74fdbb6795018a93a665fa2c417589cd4cbd51fc/layers/+chat/rcirc/img/irc.png

Description

This layer provide support for rcirc with optional support for authinfo and ZNC.

Features

  • Store channel logs into ~/.emacs.d/.cache/rcirc-logs/<channel>
  • Support for credentials stored in ~/.authinfo.gpg (need to have gnutls)
  • Support ZNC support (with optional ~/.authinfo.gpg)
  • Colored nicknames
  • WIP: Real time change when people use /s/foo/bar in the chats
  • Completion of Emojis using company-emoji (still needs a way of showing, either using the emoji layer or having a proper font) 👏

Install

Layer

To use this configuration layer, add it to your ~/.spacemacs. You will need to add rcirc to the existing dotspacemacs-configuration-layers list in this file.

Configuration

There are several ways to configure rcirc supported by the layer:

  • By storing your credentials in rcirc-server-alist in your dotfile (not secured)
  • By storing your credentials in rcirc-server-alist in your Dropbox (better but still not secured)
  • By storing your credentials in authinfo (secured)
  • By using a ZNC bouncer and storing your credentials (secured)

Storing the credentials in your dotfile

You can store your servers configuration along with your credentials in the dotspacemacs/user-config of your dotfile.

Important: This method is the less secured and it is not recommended since your dotfile is often stored in a public repository and is not crypted. This is convenient but not recommended.

Example:
(setq rcirc-server-alist
  '(("irc.freenode.net"
      :user "spacemacs_user"
      :port "1337"
      :password "le_passwd"
      :channels ("#emacs"))))

Storing the credentials in your Dropbox

You can store your servers configuration along with your credentials in your dropbox in the file ~/Dropbox/emacs/pinit-rcirc.el.

Important: This method is more secured since your file is stored in a private location but it is still not crypted on your drive. Moreover since Dropbox automatically sync your files you may have a lot of copies of the file containing your credentials. This is convenient but not recommended.

Example:
(setq rcirc-server-alist
  '(("irc.freenode.net"
      :user "spacemacs_user"
      :port "1337"
      :password "le_passwd"
      :channels ("#emacs"))))

Storing the credentials in authinfo

This method is considered secured and is the recommended way to configure rcirc.

  1. If you want to use authinfo.gpg you have to enable the support for it by setting rcirc-enable-authinfo-support to t in your dotfile:

    (setq-default dotspacemacs-configuration-layers '(
     (rcirc :variables rcirc-enable-authinfo-support t)))
  2. In your ~/.authinfo.gpg file store your credentials like this:

    machine irc.freenode.net port nickserv user <user> password <passwd>
    
  3. At last you need to provide your servers configuration in the dotspacemacs/user-config function of your dotfile:

    (setq rcirc-server-alist
    '(("irc.freenode.net"
        :user "spacemacs_user"
        :port "1337"
        :channels ("#emacs"))))

Connecting behind a ZNC bouncer and storing the credentials in authinfo

This methods is also secured since it uses authinfo but you must secure your ZNC server configuration as well!

ZNC is a popular bouncer which is easy to setup. A bouncer is a proxy that connects to your IRC channels on your behalf, instead of connecting to the IRC server you connect to your ZNC server. The ZNC server can store the discussions in a buffer while you are not connected.

Disclaimer

This assumes that you are familiar with ZNC and you have a ZNC server properly setup. If it is not the case then it is recommended to read about ZNC here. There is also an installation guide for Ubuntu here.

Note

For now authinfo is mandatory to use the ZNC configuration.

  1. To enable ZNC support set the variable rcirc-enable-znc-support to t in your dotfile:

      (setq-default dotspacemacs-configuration-layers '(
        (rcirc :variables rcirc-enable-znc-support t)))
  2. In your ~/.authinfo.gpg file store your credentials like this:

    machine freenode.spacemacsserver.me port irc user spacemacs_user/freenode password ZNC_PASSWORD
    machine geekshed.spacemacsserver.me port irc user spacemacs_user/geekshed password ZNC_PASSWORD
    

    Important port must be set to irc. This is a convention of the layer to retrieve the credentials for the ZNC configuration.

  3. Then setup your servers configuration using subdomains in the dotspacemacs/user-config function of your dotfile. The :auth keyword arguments will be replaced by the credentials stored in your ~/.authinfo.gpg.

      (setq rcirc-server-alist
       ;; This will replace :auth with the correct thing, see the doc for that function
       '(("freenode"
           :host "freenode.spacemacsserver.me"
           :port "1337"
           :auth "spacemacs_user/freenode"
           :channels ("#emacs"))
       ("geekshed"
           :host "geekshed.spacemacsserver.me"
           :port "1337"
           :auth "spacemacs_user/geekshed"
           :channels ("#jupiterbroadcasting"))))

Spacemacs Layout Support

RCIRC buffers are added automatically to the default layout for RCIRC controlled by the variable rcirc-spacemacs-layout-name (defaults to "@RCIRC") and the default binding ("i") is controlled by rcirc-spacemacs-layout-binding
