NAME

pip - Console application for running Perl 5 Installer (P5I) files

DESCRIPTION

The pip ("Perl Installation Program") console application is used to install Perl distributions in a wide variety of formats, both from CPAN and from external third-party locations, while supporting module dependencies that go across the boundary from third-party to CPAN.

Using pip you can install CPAN modules, arbitrary tarballs from both the local file-system or across the internet from arbitrary URIs.

You can use pip to ensure that specific versions of CPAN modules are installed instead of the most current version.

And beyond just single installations, you script script a series of these installations by creating a "P5I" (Perl 5 Installation) file.

A Perl 5 Installation (P5I) file is a small script-like file that describes a set of distributions to install, and integrates the installation of these distributions with the CPAN installer.

The primary use of P5I files are for installing proprietary or non-CPAN software that may still require the installation of a number of CPAN dependencies in order to function.

P5I files are also extensible, with the first line of the file specifying the name of the Perl class that implements the plan.

For the moment, the class described at the top of the P5I file must be installed.

The simple Module::Plan::Lite plan class is bundled with the main distribution, and additional types can be installed if needed.

Future Additions

Also on the development schedule for pip is the creation and installation of distributions via "P5Z" files, which are tarballs containing a P5I file, as well as all the distribution tarballs referenced by the P5I file.

It is also anticipated that pip will gain support for PAR binary packages and potentially also for ActivePerl PPM files.

USAGE

The primary use of pip is to install from a P5I script, with the canonical use case as follows:

pip directory/myplan.p5i

This command will load the plan file directory/myplan.p5i, create the plan, and then execute it.

If only a directory name is given, pip will look for a default.p5i plan in the directory. Thus, all of the following are equivalent

pip directory
pip directory/
pip directory/default.p5i

If no target is provided at all, then the current directory will be used. Thus, the following are equivalent

pip
pip .
pip default.p5i
pip ./default.p5i

Syntax of a plan file

Initially, the only plan is available is the Module::Plan::Lite (MPL) plan.

A typical MPL plan will look like the following

# myplan.p5i
Module::Plan::Lite

Process-0.17.tar.gz
YAML-Tiny-0.10.tar.gz

Direct installation of a single tarball

With the functionality available in pip, you can find that sometimes you don't even want to make a file at all, you just want to install a single tarball.

The -i option lets you pass the name of a single file and it will treat it as an installer for that single file. Further, if the extention of the tarball is .tar.gz, the -i option is implied.

For example, the following are equivalent.

# Installing with the -i|--install option
> pip Process-0.17.tar.gz
> pip -i Process-0.17.tar.gz
> pip --install Process-0.17.tar.gz

# Installing from the file as normal
> pip ./default.p5i

# myplan.p5i
Module::Plan::Lite

Process-0.17.tar.gz

The -i option can be used with any single value supported by Module::Plan::Lite (see above).

This means you can also use pip to install a distribution from any arbitrary URI, including installing direct from a subversion repository.

SUPPORT

This module is stored in an Open Repository at the following address.

http://svn.ali.as/cpan/trunk/pip

Write access to the repository is made available automatically to any published CPAN author, and to most other volunteers on request.

If you are able to submit your bug report in the form of new (failing) unit tests, or can apply your fix directly instead of submitting a patch, you are strongly encouraged to do so. The author currently maintains over 100 modules and it may take some time to deal with non-Critical bug reports or patches.

This will guarentee that your issue will be addressed in the next release of the module.

If you cannot provide a direct test or fix, or don't have time to do so, then regular bug reports are still accepted and appreciated via the CPAN bug tracker.

http://rt.cpan.org/NoAuth/ReportBug.html?Queue=pip

For other issues, for commercial enhancement and support, or to have your write access enabled for the repository, contact the author at the email address above.
