Perl
====
Enables local [Perl][1] 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*.
```console
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=$HOME/Library/Perl/5.12
make && make test && make install
```
Install *cpanminus*:
```console
curl -L http://cpanmin.us | perl - --self-upgrade
```
Perlbrew
--------
An alternative to the above is to use [Perlbrew][2], which allows for the
management of multiple, isolated Perl installations in the home directory.
plenv
-----
Yet another alternative is [plenv][3]. This is inspired from rbenv and enables
switching between multiple binary installations.
The subcommands of plenv is similar with rbenv.
Aliases
-------
### General
- `pl` is short for `perl`.
- `pld` looks up Perl documentation (`perldoc`).
- `ple` executes a one line program in a loop (`perl -wlne`).
### Perlbrew
- `plb` manages Perl environments.
- `plba` lists available Perl versions.
- `plbi` installs a Perl version.
- `plbl` lists installed Perl versions.
- `plbo` temporarily turns off Perlbrew.
- `plbO` turns off Perlbrew.
- `plbs` switches to a Perl version.
- `plbu` uninstalls a Perl version.
- `plbx` temporarily sets the Perl version to use.
### plenv
- `plv` manages Perl environments.
- `plvc` List all available plenv commands.
- `plvl` Set or show the local application-specific Perl version.
- `plvg` Set or show the global Perl version.
- `plvs` Set or show the shell-specific Perl version.
- `plvi` Install a Perl version using the perl-build plugin.
- `plvu` Uninstall a specific Perl version.
- `plvr` Rehash plenv shims (run this after installing executables).
- `plvv` Show the current Perl version and its origin.
- `plvV` List all Perl versions available to plenv.
- `plvw` Display the full path to an executable.
- `plvW` List all Perl versions that contain the given executable.
- `plvm` List cpan modules in current perl.
- `plvM` Migrate cpan modules from other version.
- `plvI` Install cpanm.
Functions
---------
- `perl-info` exposes information about the Perl environment via the
`$perl_info` associative array.
Theming
-------
To display the name of the current Perl version in a prompt, define the
following style in the `prompt_name_setup` function.
```sh
# %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.
