• Setting up emacs with a local MELPA

• =important note:= do check upfront if these procedures are ok within your company's security policies.
• This is very useful when you are behind a corporate firewall or a slow proxy or even in a situation where you have no internet connection and want to hack in emacs and want to tweak your configuration.

** option 1) @d12frosted elpa mirror *** setup

1. git clone [[https://github.com/d12frosted/elpa-mirror][d12frosted' elpa mirror]] or just put the repo inside an usb stick and place the repo in the =~/.emacs.d/mirror-elpa= folder (use the --depth 1 option to grab just the last commit):

#+BEGIN_SRC sh $ git clone --depth 1 https://github.com/d12frosted/elpa-mirror.git
#+END_SRC

2. place the provided =init.el= file in =~/.emacs.d=.
3. use the timeless and infinitely powerful editor at will.

*** init.el #+BEGIN_SRC emacs-lisp (require 'package)

  (setq package-enable-at-startup nil)
  (setq package-archives '(("melpa" . "~/.emacs.d/mirror-elpa/melpa/")
                           ("org"   . "~/.emacs.d/mirror-elpa/org/")
                           ("gnu"   . "~/.emacs.d/mirror-elpa/gnu/")))
  (package-initialize)

  (unless (package-installed-p 'use-package) ; Bootstrap John Wigley's `use-package'
    (package-refresh-contents)
    (package-install 'use-package))

  (use-package evil ; this will install evil mode even without an internet connection.
    :ensure t
    :config
    (evil-mode))
#+END_SRC

*** advantages

- You now have unlimited access to all of [[http://melpa.org][melpa]], [[http://elpa.gnu.org][elpa]] and [[http://orgmode.org/][orgmode]] without having to send/receive a single network packet.
- this also means that instead of taking minutes do download your 100+ packages, it now takes nanoseconds.

*** disadvantages

- You have to rely on @[[http://github.com/d12frosted][d12frosted]] to manually update the whole mirror. But he does a very good job at it.

** option 2) Redguardtoo's elpa-mirror *** setup 1. generate your thin-mirror out of your ~/.emacs.d/elpa folder using [[https://github.com/redguardtoo/][@redguartoo's]] [[https://github.com/redguardtoo/elpa-mirror][elpa-mirror]] =elpamr-create-mirror-for-installed= command. 2. move this thin generated mirror to =~/.emacs.d/thin-elpa-mirror/= *** init.el

#+BEGIN_SRC emacs-lisp
  (require 'package)
  (setq package-enable-at-startup nil)
  (setq package-archives '(("melpa" . "~/.emacs.d/thin-elpa-mirror/")))
  (package-initialize)

  (unless (package-installed-p 'use-package) ; Bootstrap John Wigley's `use-package'
    (package-refresh-contents)
    (package-install 'use-package))

  (use-package evil ; this will install evil mode even without an internet connection.
    :ensure t
    :config
    (evil-mode))
#+END_SRC

*** advantages

• The advantage is that you don't have to wait for @[[http://github.com/d12frosted][d12frosted]] to update his mirror.

*** disadvantage

• The disadvantage is that you are confined to the packages that you use, e.g., you can't try out new packages.
