• 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.

1. git clone 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):

$ git clone --depth 1 https://github.com/d12frosted/elpa-mirror.git  

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

(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))

• You now have unlimited access to all of melpa, elpa and 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.

• You have to rely on @d12frosted to manually update the whole mirror. But he does a very good job at it.

1. generate your thin-mirror out of your ~/.emacs.d/elpa folder using @redguartoo’s elpa-mirror elpamr-create-mirror-for-installed command.
2. move this thin generated mirror to ~/.emacs.d/thin-elpa-mirror/

(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))

• The advantage is that you don’t have to wait for @d12frosted to update his mirror.

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