=head1 NAME
CPAN - query, download and build perl modules from CPAN sites
use CPAN;
- autobundle, bundle, clean, expand, install, make, recompile, test
+ autobundle, clean, install, make, recompile, test
=head1 DESCRIPTION
-The CPAN module is designed to automate the building and installing of
-perl modules and extensions including the searching and fetching from
-the net.
+The CPAN module is designed to automate the make and install of perl
+modules and extensions. It includes some searching capabilities and
+knows how to use Net::FTP or LWP (or lynx or an external ftp client)
+to fetch the raw data from the net.
Modules are fetched from one or more of the mirrored CPAN
(Comprehensive Perl Archive Network) sites and unpacked in a dedicated
no status retained between sessions. The session manager keeps track
of what has been fetched, built and installed in the current
session. The cache manager keeps track of the disk space occupied by
-the make processes and deletes excess space in a simple FIFO style.
+the make processes and deletes excess space according to a simple FIFO
+mechanism.
+
+All methods provided are accessible in a programmer style and in an
+interactive shell style.
=head2 Interactive Mode
perl -MCPAN -e shell
-which puts you into a readline interface. You will have most fun if
+which puts you into a readline interface. You will have the most fun if
you install Term::ReadKey and Term::ReadLine to enjoy both history and
-completion.
+command completion.
Once you are on the command line, type 'h' and the rest should be
self-explanatory.
+The most common uses of the interactive modes are
+
+=over 2
+
+=item Searching for authors, bundles, distribution files and modules
+
+There are corresponding one-letter commands C<a>, C<b>, C<d>, and C<m>
+for each of the four categories and another, C<i> for any of the
+mentioned four. Each of the four entities is implemented as a class
+with slightly differing methods for displaying an object.
+
+Arguments you pass to these commands are either strings exactly matching
+the identification string of an object or regular expressions that are
+then matched case-insensitively against various attributes of the
+objects. The parser recognizes a regular expression only if you
+enclose it between two slashes.
+
+The principle is that the number of found objects influences how an
+item is displayed. If the search finds one item, the result is displayed
+as object-E<gt>as_string, but if we find more than one, we display
+each as object-E<gt>as_glimpse. E.g.
+
+ cpan> a ANDK
+ Author id = ANDK
+ EMAIL a.koenig@franz.ww.TU-Berlin.DE
+ FULLNAME Andreas König
+
+
+ cpan> a /andk/
+ Author id = ANDK
+ EMAIL a.koenig@franz.ww.TU-Berlin.DE
+ FULLNAME Andreas König
+
+
+ cpan> a /and.*rt/
+ Author ANDYD (Andy Dougherty)
+ Author MERLYN (Randal L. Schwartz)
+
+=item make, test, install, clean modules or distributions
+
+These commands take any number of arguments and investigate what is
+necessary to perform the action. If the argument is a distribution
+file name (recognized by embedded slashes), it is processed. If it is a
+module, CPAN determines the distribution file in which this module is
+included and processes that.
+
+Any C<make> or C<test> are run unconditionally. An
+
+ install <distribution_file>
+
+also is run unconditionally. But for
+
+ install <module>
+
+CPAN checks if an install is actually needed for it and prints
+I<module up to date> in the case that the distribution file containing
+the module doesnE<39>t need to be updated.
+
+CPAN also keeps track of what it has done within the current session
+and doesnE<39>t try to build a package a second time regardless if it
+succeeded or not. The C<force> command takes as a first argument the
+method to invoke (currently: C<make>, C<test>, or C<install>) and executes the
+command from scratch.
+
+Example:
+
+ cpan> install OpenGL
+ OpenGL is up to date.
+ cpan> force install OpenGL
+ Running make
+ OpenGL-0.4/
+ OpenGL-0.4/COPYRIGHT
+ [...]
+
+A C<clean> command results in a
+
+ make clean
+
+being executed within the distribution file's working directory.
+
+=item readme, look module or distribution
+
+These two commands take only one argument, be it a module or a
+distribution file. C<readme> unconditionally runs, displaying the
+README of the associated distribution file. C<Look> gets and
+untars (if not yet done) the distribution file, changes to the
+appropriate directory and opens a subshell process in that directory.
+
+=item Signals
+
+CPAN.pm installs signal handlers for SIGINT and SIGTERM. While you are
+in the cpan-shell it is intended that you can press C<^C> anytime and
+return to the cpan-shell prompt. A SIGTERM will cause the cpan-shell
+to clean up and leave the shell loop. You can emulate the effect of a
+SIGTERM by sending two consecutive SIGINTs, which usually means by
+pressing C<^C> twice.
+
+CPAN.pm ignores a SIGPIPE. If the user sets inactivity_timeout, a
+SIGALRM is used during the run of the C<perl Makefile.PL> subprocess.
+
+=back
+
=head2 CPAN::Shell
The commands that are available in the shell interface are methods in
the package CPAN::Shell. If you enter the shell command, all your
-input is split on whitespace, the first word is being interpreted as
-the method to be called and the rest of the words are treated as
-arguments to this method.
+input is split by the Text::ParseWords::shellwords() routine which
+acts like most shells do. The first word is being interpreted as the
+method to be called and the rest of the words are treated as arguments
+to this method. Continuation lines are supported if a line ends with a
+literal backslash.
+
+=head2 autobundle
+
+C<autobundle> writes a bundle file into the
+C<$CPAN::Config-E<gt>{cpan_home}/Bundle> directory. The file contains
+a list of all modules that are both available from CPAN and currently
+installed within @INC. The name of the bundle file is based on the
+current date and a counter.
+
+=head2 recompile
-If you do not enter the shell, most of the available shell commands
-are both available as methods (C<CPAN::Shell-E<gt>install(...)>) and as
+recompile() is a very special command in that it takes no argument and
+runs the make/test/install cycle with brute force over all installed
+dynamically loadable extensions (aka XS modules) with 'force' in
+effect. The primary purpose of this command is to finish a network
+installation. Imagine, you have a common source tree for two different
+architectures. You decide to do a completely independent fresh
+installation. You start on one architecture with the help of a Bundle
+file produced earlier. CPAN installs the whole Bundle for you, but
+when you try to repeat the job on the second architecture, CPAN
+responds with a C<"Foo up to date"> message for all modules. So you
+invoke CPAN's recompile on the second architecture and youE<39>re done.
+
+Another popular use for C<recompile> is to act as a rescue in case your
+perl breaks binary compatibility. If one of the modules that CPAN uses
+is in turn depending on binary compatibility (so you cannot run CPAN
+commands), then you should try the CPAN::Nox module for recovery.
+
+=head2 The four C<CPAN::*> Classes: Author, Bundle, Module, Distribution
+
+Although it may be considered internal, the class hierarchy does matter
+for both users and programmer. CPAN.pm deals with above mentioned four
+classes, and all those classes share a set of methods. A classical
+single polymorphism is in effect. A metaclass object registers all
+objects of all kinds and indexes them with a string. The strings
+referencing objects have a separated namespace (well, not completely
+separated):
+
+ Namespace Class
+
+ words containing a "/" (slash) Distribution
+ words starting with Bundle:: Bundle
+ everything else Module or Author
+
+Modules know their associated Distribution objects. They always refer
+to the most recent official release. Developers may mark their releases
+as unstable development versions (by inserting an underbar into the
+visible version number), so the really hottest and newest distribution
+file is not always the default. If a module Foo circulates on CPAN in
+both version 1.23 and 1.23_90, CPAN.pm offers a convenient way to
+install version 1.23 by saying
+
+ install Foo
+
+This would install the complete distribution file (say
+BAR/Foo-1.23.tar.gz) with all accompanying material. But if you would
+like to install version 1.23_90, you need to know where the
+distribution file resides on CPAN relative to the authors/id/
+directory. If the author is BAR, this might be BAR/Foo-1.23_90.tar.gz;
+so you would have to say
+
+ install BAR/Foo-1.23_90.tar.gz
+
+The first example will be driven by an object of the class
+CPAN::Module, the second by an object of class CPAN::Distribution.
+
+=head2 ProgrammerE<39>s interface
+
+If you do not enter the shell, the available shell commands are both
+available as methods (C<CPAN::Shell-E<gt>install(...)>) and as
functions in the calling package (C<install(...)>).
+There's currently only one class that has a stable interface -
+CPAN::Shell. All commands that are available in the CPAN shell are
+methods of the class CPAN::Shell. Each of the commands that produce
+listings of modules (C<r>, C<autobundle>, C<u>) returns a list of the
+IDs of all modules within the list.
+
+=over 2
+
+=item expand($type,@things)
+
+The IDs of all objects available within a program are strings that can
+be expanded to the corresponding real objects with the
+C<CPAN::Shell-E<gt>expand("Module",@things)> method. Expand returns a
+list of CPAN::Module objects according to the C<@things> arguments
+given. In scalar context it only returns the first element of the
+list.
+
+=item Programming Examples
+
+This enables the programmer to do operations that combine
+functionalities that are available in the shell.
+
+ # install everything that is outdated on my disk:
+ perl -MCPAN -e 'CPAN::Shell->install(CPAN::Shell->r)'
+
+ # install my favorite programs if necessary:
+ for $mod (qw(Net::FTP MD5 Data::Dumper)){
+ my $obj = CPAN::Shell->expand('Module',$mod);
+ $obj->install;
+ }
+
+ # list all modules on my disk that have no VERSION number
+ for $mod (CPAN::Shell->expand("Module","/./")){
+ next unless $mod->inst_file;
+ # MakeMaker convention for undefined $VERSION:
+ next unless $mod->inst_version eq "undef";
+ print "No VERSION in ", $mod->id, "\n";
+ }

+=head2 Methods in the four
+
=head2 Cache Manager
Currently the cache manager only keeps track of the build directory
($CPAN::Config->{build_dir}). It is a simple FIFO mechanism that
-deletes complete directories below build_dir as soon as the size of
+deletes complete directories below C<build_dir> as soon as the size of
all directories there gets bigger than $CPAN::Config->{build_cache}
(in MB). The contents of this cache may be used for later
re-installations that you intend to do manually, but will never be
-trusted by CPAN itself.
+trusted by CPAN itself. This is due to the fact that the user might
+use these directories for building modules on different architectures.
There is another directory ($CPAN::Config->{keep_source_where}) where
the original distribution files are kept. This directory is not
It starts like a perl module with a package declaration and a $VERSION
variable. After that the pod section looks like any other pod with the
-only difference, that one pod section exists starting with (verbatim):

-(eg. Foo::Bar, ie. I<not> the name of the distribution file). The rest
+(e.g. Foo::Bar, ie. I<not> the name of the distribution file). The rest
of the line is optional. The comment part is delimited by a dash just
as in the man page header.
The distribution of a bundle should follow the same convention as
-other distributions. The bundle() function in the CPAN module simply

+other distributions.
Bundles are treated specially in the CPAN package. If you say 'install
Bundle::Tkkit' (assuming such a bundle exists), CPAN will install all
-the modules in the CONTENTS section of the pod. You can install your
+the modules in the CONTENTS section of the pod. You can install your
own Bundles locally by placing a conformant Bundle file somewhere into
your @INC path. The autobundle() command which is available in the
shell interface does that for you by including all currently installed
modules in a snapshot bundle file.
-=head2 autobundle
+=head2 Prerequisites
-autobundle() writes a bundle file into the directory
-$CPAN::Config->{cpan_home}/Bundle directory. The file contains a list
-of all modules that are both available from CPAN and currently
-installed within @INC. The name of the bundle file is based on the
-current date and a counter.
+If you have a local mirror of CPAN and can access all files with
+"file:" URLs, then you only need a perl better than perl5.003 to run
+this module. Otherwise Net::FTP is strongly recommended. LWP may be
+required for non-UNIX systems or if your nearest CPAN site is
+associated with an URL that is not C<ftp:>.
-=head2 Pragma: force
+If you have neither Net::FTP nor LWP, there is a fallback mechanism
+implemented for an external ftp command or for an external lynx
+command.
-Normally CPAN keeps track of what it has done within the current
-session and doesn't try to build a package a second time regardless if
-it succeeded or not. The force command takes as first argument the
-method to invoke (currently: make, test, or install) and executes the
-command from scratch.
+=head2 Finding packages and VERSION
-Example:
+This module presumes that all packages on CPAN
- cpan> install OpenGL
- OpenGL is up to date.
- cpan> force install OpenGL
- Running make
- OpenGL-0.4/
- OpenGL-0.4/COPYRIGHT

-=head2 recompile

-runs the make/test/install cycle with brute force over all installed
-dynamically loadable extensions (aka XS modules) with 'force' in

+declare their $VERSION variable in an easy to parse manner. This
+prerequisite can hardly be relaxed because it consumes far too much
+memory to load all packages into the running program just to determine
+the $VERSION variable. Currently all programs that are dealing with
+version use something like this
+
+ perl -MExtUtils::MakeMaker -le \
+ 'print MM->parse_version($ARGV[0])' filename
+
+If you are author of a package and wonder if your $VERSION can be

+Makefile.PL (well, we try to handle a bit more, but without much
+enthusiasm).

+
+=head2 Debugging
+
+The debugging of this module is pretty difficult, because we have
+interferences of the software producing the indices on CPAN, of the
+mirroring process on CPAN, of packaging, of configuration, of
+synchronicity, and of bugs within CPAN.pm.
+
+In interactive mode you can try "o debug" which will list options for
+debugging the various parts of the package. The output may not be very
+useful for you as it's just a by-product of my own testing, but if you
+have an idea which part of the package may have a bug, it's sometimes
+worth to give it a try and send me more specific output. You should
+know that "o debug" has built-in completion support.
+
+=head2 Floppy, Zip, and all that Jazz
+
+CPAN.pm works nicely without network too. If you maintain machines
+that are not networked at all, you should consider working with file:
+URLs. Of course, you have to collect your modules somewhere first. So
+you might use CPAN.pm to put together all you need on a networked
+machine. Then copy the $CPAN::Config->{keep_source_where} (but not
+$CPAN::Config->{build_dir}) directory on a floppy. This floppy is kind
+of a personal CPAN. CPAN.pm on the non-networked machines works nicely
+with this floppy.

+=head2 CD-ROM support
+
+The C<urllist> parameter of the configuration table contains a list of
+URLs that are to be used for downloading. If the list contains any
+C<file> URLs, CPAN always tries to get files from there first. This
+feature is disabled for index files. So the recommendation for the
+owner of a CD-ROM with CPAN contents is: include your local, possibly
+outdated CD-ROM as a C<file> URL at the end of urllist, e.g.
+
+ o conf urllist push file://localhost/CDROM/CPAN
+
+CPAN.pm will then fetch the index files from one of the CPAN sites
+that come at the beginning of urllist. It will later check for each
+module if there is a local copy of the most recent version.
+
=head1 SECURITY
There's no strong security layer in CPAN.pm. CPAN.pm helps you to
to a checksum that comes from the net just as the distribution file
itself. If somebody has managed to tamper with the distribution file,
they may have as well tampered with the CHECKSUMS file. Future
