prezto/modules/perl

Perl

Enables local Perl module installation on macOS 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 macOS 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.

plenv

Yet another alternative is plenv. This is inspired from rbenv and enables switching between multiple binary installations.

The subcommands of plenv is similar with rbenv.

Aliases

Aliases are enabled by default. To disable them, add the following to ${ZDOTDIR:-$HOME}/.zpreztorc.

zstyle ':prezto:module:perl:alias' skip 'yes'

Theming

To display the name of the current 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.
