Create local Emacs package repository from installed packages so package upgrade never breaks.

• Why

• Package installation is fast. It takes only 15 seconds to install 115 packages

• The package repository could be hosted on USB/Dropbox/GitHub

• Tested with Emacs 27, 28, 29 on OSX/Cygwin/Windows10/Linux

• Install CLI program "tar" is required. It's already installed on Windows10/Linux/macOS.

• Download =elpa-mirror.el= to somewhere (say =~/.emacs.d/site-lisp/elpa-mirror/=)

• Add below code into "~/.emacs",

  +begin_src elisp

  (add-to-list 'load-path "~/.emacs.d/site-lisp/elpa-mirror") (require 'elpa-mirror)

  +end_src

• Usage =M-x elpamr-create-mirror-for-installed= to create local repository.

To update existing local repository, run =M-x elpamr-create-mirror-for-installed= again.

BTW, =elpa-mirror.el= can run as an independent script,

+begin_src sh

mkdir -p ~/myelpa && emacs --batch -l ~/.emacs.d/init.el -l ~/any-directory-you-prefer/elpa-mirror.el --eval='(setq elpamr-default-output-directory "~/myelpa")' --eval='(elpamr-create-mirror-for-installed)'

+end_src

To use the local repository =~/myelpa/=, insert below code into =~/.emacs=,

+begin_src elisp

;; myelpa is the ONLY repository now, dont forget trailing slash in the directory (setq package-archives '(("myelpa" . "~/myelpa/")))

+end_src

** Repository on Dropbox Insert below code into =~/.emacs=:

+begin_src elisp

;; add-to-list will not override default elpa. ;; So now you have two repositories. ;; One is GNU elpa. Another is myelpa (add-to-list 'package-archives '("myelpa" . "https://dl.dropboxusercontent.com/u/858862/myelpa/"))

+end_src

** Repository on GitHub My repository is [[https://github.com/redguardtoo/myelpa]].

Insert below code into =.emacs=:

+begin_src elisp

;; add-to-list will not override default elpa. ;; So now you have two repositories. ;; One is GNU elpa. Another is myelpa (add-to-list 'package-archives '("myelpa" . "https://raw.githubusercontent.com/redguardtoo/myelpa/master/"))

+end_src

• Tips Exclude packages See =elpamr-exclude-packages=. Exclude files/directories in package directory See =elpamr-tar-command-exclude-patterns=.

=elpamr-exclude-patterns-filter-function= lets users define a filter function to exclude files and directories per package. The function returns the result to replace =elpamr-tar-command-exclude-patterns=.

Below setup adds directory "bin/" into package "vagrant-tramp".

+begin_src elisp

(setq elpamr-exclude-patterns-filter-function (lambda (package-dir) (let ((patterns elpamr-tar-command-exclude-patterns)) (when (string-match "vagrant-tramp" package-dir) (setq patterns (remove "*/bin" patterns))) patterns)))

+end_src

** Change output directory,

+begin_src elisp

(setq elpamr-default-output-directory "~/myelpa")

+end_src
