NAME
App::perlbrew - Manage perl installations in your $HOME
SYNOPSIS
# Initialize
perlbrew init
# Install some Perls
perlbrew install perl-5.12.1
perlbrew install perl-5.8.1
perlbrew install perl-5.11.5
# See what were installed
perlbrew installed
# Switch perl in the $PATH
perlbrew switch perl-5.12.1
perl -v
# Switch to another version
perlbrew switch perl-5.8.1
perl -v
# Switch to a certain perl executable not managed by perlbrew.
perlbrew switch /usr/bin/perl
# Or turn it off completely. Useful when you messed up too deep.
perlbrew off
# Use 'switch' command to turn it back on.
perlbrew switch perl-5.12.1
DESCRIPTION
perlbrew is a program to automate the building and installation of perl
in the users HOME. At the moment, 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's almost like an isolated perl environments.
INSTALLATION
The recommended way to install perlbrew is to run these statements in
your shell:
curl -LO http://xrl.us/perlbrew
chmod +x perlbrew
./perlbrew install
After that, "perlbrew" installs itself to "~/perl5/perlbrew/bin", and
you should follow the instruction on screen to setup your ".bashrc" or
".cshrc" to put it in your PATH.
The directory "~/perl5/perlbrew" will contain all install perl
executables, libraries, documentations, lib, site_libs. If you need to
install "perlbrew", and the perls it brews, into somewhere else because,
say, your HOME has limited quota, you can do that by setting a
"PERLBREW_ROOT" environment variable before you run "./perlbrew
install".
export PERLBREW_ROOT=/mnt/perlbrew
./perlbrew install
The downloaded perlbrew is a self-contained standalone program that
embed all non-core modules it uses. It should be runnable with perl 5.8
or high versions of perls.
You may also install perlbrew from CPAN with cpan / cpanp / cpanm:
cpan App::perlbrew
This installs 'perlbrew' into your current PATH and it is always
executed with your current perl.
NOTICE. When you install or upgrade perlbrew with cpan / cpanp / cpanm,
make sure you are not using one of the perls brewed with perlbrew. If
so, the `perlbrew` executable you just installed will not be available
after you swith to other perls. You might not be able to invoke further
"perlbrew" commands after so because the executable "perlbrew" is not in
your "PATH" anymore. Installing it again with cpan can temporarily
solved this problem.
It should be relatively safe to install "App::perlbrew" with system cpan
(like "/usr/bin/cpan") because then it will be installed under a system
PATH like "/usr/bin", which is not effected by "perlbrew switch"
command.
Again, it is recommended to let "perlbrew" install itself. It's easier,
and it works better.
USAGE
Please read the program usage by running
perlbrew
(No arguments.) To read a more detail one:
perlbrew -h
Alternatively, this should also do:
perldoc perlbrew
If you messed up to much or get confused by having to many perls
installed, you can do:
perlbrew switch /usr/bin/perl
It will make sure that your current perl in the PATH is pointing to
"/usr/bin/perl".
As a matter of fact the "switch" command checks whether the given
argument is an executale or not, and create a symlink named 'perl' to it
if it is. If you really want to you are able to do:
perlbrew switch /usr/bin/perl6
But maybe not. After running this you might not be able to run perlbrew
anymore. So be careful not making mistakes there.
