Starter Kit Package Manager

This is part of the Emacs Starter Kit.

Starter Kit Package Manager

Since emacs version 24, elisp code can be downloaded, installed and loaded almost automatically with package.el. There are still some discussions on how to use it properly (see B. Batsov article for example). In this file, we use the “usual” way through ELPA for most of the packages to be installed. Nevertheless, we also define some el-get command to install some packages a bit oldy and not supported by any ELPA repository.

Checking internet connection

If there is no internet connection then no way to use any of the package managers. This should not work under Windows system since it does not have the network-interface-list function

(defun sk-elpa-online ()
  "Check internet connectivity."
  (if (and (functionp 'network-interface-list)
           (network-interface-list))
      (some (lambda (iface) (unless (equal "lo" (car iface))
                         (member 'up (first (last (network-interface-info
                                                   (car iface)))))))
            (network-interface-list)) t))

ELPA

Defining ELPA sources

(setq package-archives
      '(("gnu"         . "http://elpa.gnu.org/packages/")
        ("melpa"       . "http://melpa.org/packages/")))
(package-initialize)
(unless (file-exists-p "~/.emacs.d/elpa/archives/melpa")
  (package-refresh-contents))

(defun starter-packages-install (packages)
  (dolist (it packages)
    (when (not (package-installed-p it))
      (package-install it)))
  (delete-other-windows))

On-demand installation of packages

(defun require-package (package &optional min-version no-refresh)
  "Install given PACKAGE, optionally requiring MIN-VERSION.
If NO-REFRESH is non-nil, the available package lists will not be
re-downloaded in order to locate PACKAGE."
  (if (package-installed-p package min-version)
      t
    (if (or (assoc package package-archive-contents) no-refresh)
        (package-install package)
      (progn
        (package-refresh-contents)
        (require-package package min-version t)))))

el-get

=el-get= allows you to install and manage elisp code for Emacs. It supports lots of differents types of sources and is able to install them, update them and remove them, but more importantly it will init them for you. The next pieces of code are largely inspired by this article.

Checking el-get

(add-to-list 'load-path "~/.emacs.d/el-get/el-get")
(unless (require 'el-get nil t)
  (with-current-buffer
      (url-retrieve-synchronously
       "https://raw.github.com/dimitri/el-get/master/el-get-install.el")
    (end-of-buffer)
    (eval-print-last-sexp)))

Setup packages

(setq el-get-sources
     '((:name trac-wiki
        :description "Simple but efficient interface to Trac."
        :type github
        :pkgname "tiborsimko/trac-wiki-el")
       (:name emacs-deferred
        :description "Facilities to manage asynchronous tasks."
        :type github
        :pkgname "kiwanami/emacs-deferred")
       (:name inertial-scroll
        :description "Soft mouse scrolling."
        :type github
        :pkgname "kiwanami/emacs-inertial-scroll")
       (:name ox-ioslide
        :description "Export your Org document to Google I/O HTML5 slide."
        :type github
        :pkgname "coldnew/org-ioslide")
       )
     )
