A shared perlbrew root for multiple users

作者：gugod 發佈於：2010/12/07 https://gugod.org/2010/12/a-shared-perlbrew-root-for-multiple-users/

Perhaps the biggest advantage of using perlbrew 0.15, is the possibility to share one perlbrew root among multiple users, assuming everyone uses bash (or zsh, which is compatible to bash.)

Let's assume the following scenario:

the global perlbrew is located at /opt/perlbrew
a user named perlbrew has write permission, and can install new perls and modules
all other users have read-only access

This distribution is managed using Dist::Zilla. If all you want to do is to install the latest stable distribution of {{dist}}, your best bet is to install it from CPAN using your usual CPAN client:

$ cpanm {{dist}} # cpan or cpanp also work

If you want to install this GitHub version of the distribution you need to have an up-to-date installation of Dist::Zilla. This is more complicated than installing direct from CPAN.

Packages, Modules and Distributions

First, module dependencies are declared using a package, not a distribution. If your application uses LWP::UserAgent, you have to declare:

requires 'LWP::UserAgent' => '5.20'; # Known minimum version of the module

instead of "libwww-perl" "5.20".

	#!/bin/bash

	set -o errexit # exit on error
	set -o pipefail # trap pipe fails
	set -o nounset # trap unset vars

	DEST="/usr/local"
	SOURCE="$HOME/emacs-28.1"
	NATIVE_FULL_AOT='' # 'NATIVE_FULL_AOT=1' # removed in emacs 28.1
	JOBS='-j 3'

	#!/bin/bash

	set -e # exit on error

	GCC_VER=$(gcc -dumpversion)

	sudo apt install \
	autoconf \
	automake \
	build-essential \

	(define-derived-mode run-mode
	special-mode "Run"
	"help!!!"
	:init-value nil)

	(defun run-perl-on-current-buffer-file ()
	(interactive)
	(save-buffer)
	(setq filename (buffer-file-name (current-buffer)))
	(delete-other-windows)

	(setq plistlist '( (:number 1 :name "one")
	(:number 2 :name "two") ))

	(setq result (seq-find (lambda (elt)
	(eq (plist-get elt :number) 2) )
	plistlist) )

	(message "%s" result)
