worries when elpa is down :en:emacs:package:elpa:

I use one liner shell command to clone Emacs Lisp Package Archive (ELPA):

mkdir -p ~/elpaclone && cd ~/elpaclone && curl -L https://elpa.gnu.org/packages/archive-contents | perl -pe 's/(^\(1|\n)//g' | perl -pe 's/\]\)/])\n/g' | perl -pe 's/^ *\(([a-z0-9A-Z-]*).*\[\(([0-9 ]*).*(single|tar).*/\1-\2.\3/g' | perl -pe 's/ /./g' | perl -pe 's/single/el/g' | perl -pe 's/\)//g' | xargs -I {} curl -L  -O https://elpa.gnu.org/packages/{} && curl -L -O https://elpa.gnu.org/packages/archive-contents

The https://elpa.gnu.org/packages/archive-contents contains all the information of packages. I re-organize it to make sure each line corresponds to one package. Then I use cURL to download everything.

Usage is simple.

Insert below line at the beginning of ~/.emacs when elpa.gnu.org is down:

(setq package-archives '(("elpaclone" . "~/elpaclone")))

This solution also works for MELPA.
