Indrajit Raychaudhuri d80e393f78 general: Reformat documentation with better formatting and wording 
General purpose reformating and rewording in (a few places). This should
also make markdown linting happier.

Prefer back-ticks wherever useful and use `console` for code blocks to
be executed on terminal.

Also, update references links wherever possible (including update from
'http://' to 'https://').

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

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)

  • 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)

  • 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.

# %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.
