Perl

Enables local Perl module installation on Mac OS X and defines aliases.

Local Module Installation

Perl versions older than 5.14 do not support the local installation of Perl modules natively. This module allows for local installation of Perl modules on Mac OS X in ~/Library/Perl/5.12 by altering the environment.

Usage

For Perl versions older than 5.14, install local::lib.

curl -L -C - -O http://search.cpan.org/CPAN/authors/id/A/AP/APEIRON/local-lib-1.008004.tar.gz
tar xvf local-lib-1.008004.tar.gz
cd local-lib-1.008004
perl Makefile.PL --bootstrap=$HOME/Library/Perl/5.12
make && make test && make install

Install cpanminus:

curl -L http://cpanmin.us | perl - --self-upgrade

Perlbrew

An alternative to the above is to use Perlbrew, which allows for the management of multiple, isolated Perl installations in the home directory.

Aliases

General

• pl is short for perl.
• pld looks up Perl documentation (perldoc).
• ple executes a one line program in a loop (perl -wlne).

Perlbrew

• plb manages Perl environments.
• plba lists available Perl versions.
• plbi installs a Perl version.
• plbl lists installed Perl versions.
• plbo temporarily turns off Perlbrew.
• plbO turns off Perlbrew.
• plbs switches to a Perl version.
• plbu uninstalls a Perl version.
• plbx temporarily sets the Perl version to use.

Functions

• perl-info exposes information about the Perl environment via the $perl_info associative array.

Theming

To display the name of the currach Perl version in a prompt, define the following style in the prompt_name_setup function.

# %v - perl version.
zstyle ':prezto:module:perl:info:version' format 'version:%v'

Then add $perl_info[version] to $PROMPT or $RPROMPT and call perl-info in the prompt_name_precmd hook function.
