CPANPLUS - API & CLI access to the CPAN mirrors
### standard invocation from the command line
$ cpanp
$ cpanp -i Some::Module
$ perl -MCPANPLUS -eshell
$ perl -MCPANPLUS -e'fetch Some::Module'
The CPANPLUS library is an API to the CPAN mirrors and a collection of interactive shells, commandline programs, etc, that use this API.
This is the document you are currently reading. It describes basic usage and background information. Its main purpose is to assist the user who wants to learn how to invoke CPANPLUS and install modules from the commandline and to point you to more indepth reading if required.
The CPANPLUS API is meant to let you programmatically interact with the CPAN mirrors. The documentation in CPANPLUS::Backend shows you how to create an object capable of interacting with those mirrors, letting you create & retrieve module objects. CPANPLUS::Module shows you how you can use these module objects to perform actions like installing and testing.
The default shell, documented in CPANPLUS::Shell::Default is also scriptable. You can use its API to dispatch calls from your script to the CPANPLUS Shell.
You can start an interactive shell by running either of the two following commands:
$ cpanp
$ perl -MCPANPLUS -eshell
All commans available are listed in the interactive shells help menu. See cpanp -h or CPANPLUS::Shell::Default for instructions on using the default shell.
By running cpanp without arguments, you will start up the shell specified in your config, which defaults to CPANPLUS::Shell::Default. There are more shells available. CPANPLUS itself ships with an emulation shell called CPANPLUS::Shell::Classic that looks and feels just like the old CPAN.pm shell.
You can start this shell by typing:
$ perl -MCPANPLUS -e'shell Classic'
Even more shells may be available from CPAN.
Note that if you have changed your default shell in your configuration, that shell will be used instead. If for some reason there was an error with your specified shell, you will be given the default shell.
cpan2dist is a commandline tool to convert any distribution from CPAN into a package in the format of your choice, like for example .deb or FreeBSD ports.
See cpan2dist -h for details.
For quick access to common commands, you may use this module, CPANPLUS rather than the full programmatic API situated in CPANPLUS::Backend. This module offers the following functions:
This function requires the full name of the module, which is case sensitive. The module name can also be provided as a fully qualified file name, beginning with a /, relative to the /authors/id directory on a CPAN mirror.
It will download, extract and install the module.
