DESCRIPTION ^

perlbrew is a program to automate the building and installation of perl in an easy way. It installs everything to ~/perl5/perlbrew, and requires you to tweak your PATH by including a bashrc/cshrc file it provides. You then can benefit from not having to run 'sudo' commands to install cpan modules because those are installed inside your HOME too. It provides multiple isolated perl environments, and a mechanism for you to switch between them.

For the documentation of perlbrew usage see perlbrew command on CPAN, or by running perlbrew help. The following documentation features the API of App::perlbrew module, and may not be remotely close to what your want to read.

INSTALLATION ^

It is the simplest to use the perlbrew installer, just paste this statement to your terminal:

    curl -kL http://install.perlbrew.pl | bash

Or this one, if you have fetch (default on FreeBSD):

    fetch -o- http://install.perlbrew.pl | sh

After that, perlbrew installs itself to ~/perl5/perlbrew/bin, and you should follow the instruction on screen to modify your shell rc file to put it in your PATH.

The installed perlbrew command is a standalone executable that can be run with system perl. The minimum system perl version requirement is 5.8.0, which should be good enough for most of the OSes these days.

A packed version of patchperl to ~/perl5/perlbrew/bin, which is required to build old perls.

The directory ~/perl5/perlbrew will contain all install perl executables, libraries, documentations, lib, site_libs. In the documentation, that directory is referred as "perlbrew root". If you need to set it to somewhere else because, say, your HOME has limited quota, you can do that by setting PERLBREW_ROOT environment variable before running the installer:

    export PERLBREW_ROOT=/opt/perl5
    curl -kL http://install.perlbrew.pl | bash

You may also install perlbrew from CPAN:

    cpan App::perlbrew

In this case, the perlbrew command is installed as /usr/bin/perlbrew or /usr/local/bin/perlbrew or others, depending on the location of your system perl installation.

Please make sure not to run this with one of the perls brewed with perlbrew. It's the best to turn perlbrew off before you run that, if you're upgrading.

    perlbrew off
    cpan App::perlbrew

You should always use system cpan (like /usr/bin/cpan) to install App::perlbrew because it will be installed under a system PATH like /usr/bin, which is not affected by perlbrew switch or use command.

The self-upgrade command will not upgrade the perlbrew installed by cpan command, but it is also easy to upgrade perlbrew by running `cpan App::perlbrew` again.

METHODS ^

(Str) current_perl

Return the "current perl" object attribute string, or, if absent, the value of PERLBREW_PERL environment variable.

(Str) current_perl (Str)

Set the "current_perl" object attribute to the given value.
