Description

Installs perlbrew and provides resource/provider types for managing perls with perlbrew.

To date, this cookbook has only been designed and tested on the Ubuntu and Debian platforms.

Requirements

Perlbrew components are downloaded from the web and requires a system-installed perl to run. Perlbrew managed perls are built from source and require a standard compiler toolchain. The following packages are required (and will be installed if missing)

  • curl
  • perl
  • build-essential

Attributes

  • node['perlbrew']['perlbrew_root'] = "/opt/perlbrew" - Sets the PERLBREW_ROOT environment variable
  • node['perlbrew']['perls'] = [] - An array of perls to install, e.g. ["perl-5.14.2", "perl-5.12.3"]
  • node['perlbrew']['install_options'] = '' - A string of command line options for perlbrew install, e.g. -D usethreads for building all perls with threads

Recipes

perlbrew

Installs/updates perlbrew along with patchperl and cpanm. This is required for use of the LWRP. Optionally installs perls specified in the node['perlbrew']['perls'] attribute list.

Resources/Providers

perlbrew_perl

This LWRP installs perls into node['perlbrew']['perlbrew_root'] using perlbrew.

# option 1
perlbrew_perl perl-VERSION do
  action :install
end

# option 2
perlbrew_perl NICKNAME do
  version perl-VERSION
  action :install
end

Example:

perlbrew_perl '5.14.2' do
  version 'perl-5.14.2'
  action :install
end

This is equivalent to perlbrew install perl-5.14.2 --as 5.14.2.

Actions:

  • :install - install the specified perl (default action)
  • :remove - uninstall the specified perl

Attributes:

  • :version - the version of perl to install, in the "perl-X.Y.Z" format that perlbrew expects This is based on the perlbrew_perl name if not provided.
  • :install_options - overrides the default install options on the node. (Not recommended.)

perlbrew_lib

This LWRP creates a perlbrew-based local::lib library for a particular perlbrew perl.

Example:

perlbrew_lib 'perl-5.14.2@mylib' do
  action :create
end

This is equivalent to perlbrew lib create perl-5.14.2@mylib

Action:

  • :create - creates the local::lib (default action)
  • :delete - removes the local::lib

Attributes:

  • :perlbrew - the perlbrew perl to attach the library to (e.g. 'perl-5.14.2'). It will be derived from the perlbrew_lib name if not provided. The perlbrew perl will be installed using the perlbrew_perl LRWP if it has not already been installed.

perlbrew_cpanm

This LWRP installs CPAN modules to a given perlbrew perl or local::lib using cpanm (App::cpanminus).

Example:

perlbrew_cpanm 'Modern Perl modules' do
  perlbrew 'perl-5.14.2@mylib'
  modules ['Modern::Perl', 'Task::Kensho']
end

This is equivalent to

$ perlbrew use perl-5.14.2@mylib
$ cpanm Modern::Perl Task::Kensho

Note that the resource name "Modern Perl modules" will be associated with a set of modules only once. The name should be unique for any particular chef run.

Action:

  • :install - install the list of modules (default action)

Attributes:

  • :perlbrew - the perlbrew perl (and optional library) to use for installing modules (REQUIRED)
  • :modules - an array of module names to pass to cpanm. Any legal input to cpanm is allowed.

perlbrew_run

This LWRP runs a bash command in the context of a given perlbrew perl or local::lib.

Example 1:

perlbrew_run 'Perl hello world' do
  perlbrew 'perl-5.14.2@mylib'
  command "perl -wE 'say q{Hello World}'"
end

This is equivalent to

$ perlbrew use perl-5.14.2@mylib
$ perl -wE 'say q{Hello World}'

Example 2:

perlbrew_run 'hello-world.pl' do
  perlbrew 'perl-5.14.2@mylib'
end

This is equivalent to

$ perlbrew use perl-5.14.2@mylib
$ hello-world.pl

Note that the resource name will only be executed once for a given chef run.

Action:

  • :run - runs the command (default action)

Attributes:

  • :perlbrew - the perlbrew perl (and optional library) to be enabled prior to running the command (REQUIRED)
  • :command - the bash command to run; taken from the resource name if not provided
  • :cwd - directory to enter prior to running the command, just like the bash resource attribute
  • :environment - hash of environment variables to set prior to running the command, just like the bash resource attribute

Usage

If you wish to use the LWRP, be sure to include the perlbrew recipe, which ensures that perlbrew is ready for use.
