Learn how to manage Emacs packages well.

How about using use-package

• Write a readable init.el in use-package - Qiita

There are all the elements you need to write .emacs, such as post-load settings, conditional branches, delay loads, and key settings.Plus, the library can be loaded and configured in one S formula, making it more readable.

If package.el requires automatic installation of external packages, add :ensuret to the argument.Without it, AutoInstall will not occur and the configuration will be skipped.

 (use-package magit)
  :ensuret)

How about el-get

If you write a recipe like this (e.g., ~/.emacs.d/el-get-user/recipes/migemo.rcp),

 (:name migemo)
   :description "Japanese incremental search through dynamic pattern expansion."
   —website "http://0xcc.net/migemo/"
   —type github
   : pkgname "emacs-jp/migemo")

.emacs or .emacs.d/init.el can be installed at startup by simply writing:

 (add-to-list'load-path"~/.emacs.d/el-get/el-get")

(unless(require'el-get nil'no error)
  (with-current-buffer
      (url-retrieve-synchronously
       "https://raw.githubusercontent.com/dimitri/el-get/master/el-get-install.el")
    (goto-char (point-max))
    (eval-print-last-seexp))

(add-to-list'el-get-recipe-path"~/.emacs.d/el-get-user/recipes")
(el-get'sync)

(el-get'sync'migemo)

Addition by @uchida

It also supports the elpa package.

If you wrote the above in .emacs.d/init.el, you can create recipes from the elpa package from to/.emacs.d/el-get/el-get/recipe/elpa.

 (require'el-get-elpa)
(unless (file-directory-pel-get-recipe-path-elpa)
  (el-get-elpa-build-local-recipes))

Therefore, in addition to your own recipe, you can install the elpa package as follows:

(defvar my/el-get-packages' (package names here))
(el-get'sync my/el-get-packages)

As for the questioner, I am posting because I have a certain successful approach to this issue.

Define the following with init.el or any .el (where hoge.el)

 (require'package)
(add-to-list 'package-archives' ("melpa". "http://melpa.milkbox.net/packages/"))
(add-to-list 'package-archives' ("marmalade". "http://marmalade-repo.org/packages/"))
(package-initialize)

This section uses packages, adds repositories to use, and initializes packages.Change the repository as needed.

 (defvar my/favorite-packages)
  '(package names here))

Here we define a list and write the name of the package exactly as it is , such as popwin.

 (defun set-pac()
  "my package install command"
  (interactive)
  (package-refresh-contents)
  (dolist (package my/favorite-packages)
    (when (not (package-installed-package))
    (package-install package)))

This command updates the package information and installs packages that are not included.

To install the package, do one of the following:

• Start Emacs and then run M-xset-pac
• emacs--batch-l path/to/hoge.el-f'set-pac'

For path/to/hoge.el, write the init.el or any .el location that defines the variables and functions above. If defined in init.el, it will probably be ~/.emacs.d/init.el.

This method is complete with only configuration files and Emacs, as well as auto-installation on multiple operating systems that Emacs can handle in the package.el of Emacs.

I hope it will be helpful for someone.

Note: "Kosh said ""use-package"" and ""use-package"" was a very good extension." However, use-package is a bootstrap problem, so only package.el will write an Emacs Lisp to automatically install use-package.

Assume the first block of code in this answer (requiring)

(when (not (package-installed-p 'use-package))
  (package-refresh-contents)
  (package-install 'use-package))

(require 'use-package)

If you write something like this before the use-package part of init.el, you can use the use-package as it is without having to install it manually.

I hope this will also be helpful.
