* qorg's Emacs config

  This is my Emacs configuration. Hope you like it.

** Installation

   Just copy this repository to your .emacs.d. Nothing else is needed.

** Why?
   * I can
   * I don't like doom emacs
   * I don't like spacemacs
   * I don't want to learn doom emacs
   * I don't want to learn spacemacs
   * I don't like Vim
** About me
   Here I set variables about personal information i'll use later in
   this config.
   #+BEGIN_SRC emacs-lisp
   (setq name "qorg11")
   (setq email "qorg@vxempire.xyz")
   (setq website "qorg11.net")
   #+END_SRC
** Dependencies
   The only no emacs related dependence in this configuration is the
   IBM Plex Mono font. Install it from your distribution packages.
   You can change it before opening Emacs with this configuration for
   the first time.

   For irony-mode (C autocompletion) irony-sever must be
   installed. You can install it with M-x irony-install-server or via
   distribution's packages, in Debian case, apt install irony-server.
   Using M-x irony-install-server requires cmake and a lot of
   dependences I'm to lazy to install.

* melpa crap, and basic packages installation
  melpa, where you get the packages. This also installs use-package,
  and other packages I use.
  #+BEGIN_SRC emacs-lisp

    (let* ((no-ssl (and (memq system-type '(windows-nt ms-dos))

** Generic packages
   Here I install some packages that don't need configuration.
   Remember to run M-x all-the-icons-install-fonts after the first
   init to install the fonts.
