- =head1 NAME
-
- CPAN - query, download and build perl modules from CPAN sites
-
- =head1 SYNOPSIS
-
- Interactive mode:
-
- perl -MCPAN -e shell;
-
- Batch mode:
-
- use CPAN;
-
- autobundle, clean, install, make, recompile, test
-
- =head1 DESCRIPTION
-
- 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
- directory.
-
- The CPAN module also supports the concept of named and versioned
- 'bundles' of modules. Bundles simplify the handling of sets of
- related modules. See BUNDLES below.
-
- The package contains a session manager and a cache manager. There is
- 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 according to a simple FIFO
- mechanism.
-
- All methods provided are accessible in a programmer style and in an
- interactive shell style.
-
- =head2 Interactive Mode
-
- The interactive mode is entered by running
-
- perl -MCPAN -e shell
-
- 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
- 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 K÷nig
-
-
- cpan> a /andk/
- Author id = ANDK
- EMAIL a.koenig@franz.ww.TU-Berlin.DE
- FULLNAME Andreas K÷nig
-
-
- 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 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
-
- 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 ", $mod->id, "\n";
- }
-
- =back
-
- =head2 Methods in the four
-
- =head2 Cache Manager
-
- Currently the cache manager only keeps track of the build directory
- ($CPAN::Config->{build_dir}). It is a simple FIFO mechanism that
- deletes complete directories below C<build_dir> as soon as the size of
- all directories there gets bigger than $CPAN::Config->{build_cache}
- (in MB). The contents of this cache may be used for later
- re-installations that you intend to do manually, but will never be
- trusted by CPAN itself. This is due to the fact that the user might
- use these directories for building modules on different architectures.
-
- There is another directory ($CPAN::Config->{keep_source_where}) where
- the original distribution files are kept. This directory is not
- covered by the cache manager and must be controlled by the user. If
- you choose to have the same directory as build_dir and as
- keep_source_where directory, then your sources will be deleted with
- the same fifo mechanism.
-
- =head2 Bundles
-
- A bundle is just a perl module in the namespace Bundle:: that does not
- define any functions or methods. It usually only contains documentation.
-
- 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 being that I<one special pod section> exists starting with
- (verbatim):
-
- =head1 CONTENTS
-
- In this pod section each line obeys the format
-
- Module_Name [Version_String] [- optional text]
-
- The only required part is the first field, the name of a module
- (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.
-
- 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
- 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 Prerequisites
-
- 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:>.
-
- 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.
-
- =head2 Finding packages and VERSION
-
- This module presumes that all packages on CPAN
-
- =over 2
-
- =item *
-
- 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
- parsed, please try the above method.
-
- =item *
-
- come as compressed or gzipped tarfiles or as zip files and contain a
- Makefile.PL (well, we try to handle a bit more, but without much
- enthusiasm).
-
- =back
-
- =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.
-
- =head1 CONFIGURATION
-
- When the CPAN module is installed, a site wide configuration file is
- created as CPAN/Config.pm. The default values defined there can be
- overridden in another configuration file: CPAN/MyConfig.pm. You can
- store this file in $HOME/.cpan/CPAN/MyConfig.pm if you want, because
- $HOME/.cpan is added to the search path of the CPAN module before the
- use() or require() statements.
-
- Currently the following keys in the hash reference $CPAN::Config are
- defined:
-
- build_cache size of cache for directories to build modules
- build_dir locally accessible directory to build modules
- index_expire after this many days refetch index files
- cpan_home local directory reserved for this package
- gzip location of external program gzip
- inactivity_timeout breaks interactive Makefile.PLs after this
- many seconds inactivity. Set to 0 to never break.
- inhibit_startup_message
- if true, does not print the startup message
- keep_source keep the source in a local directory?
- keep_source_where directory in which to keep the source (if we do)
- make location of external make program
- make_arg arguments that should always be passed to 'make'
- make_install_arg same as make_arg for 'make install'
- makepl_arg arguments passed to 'perl Makefile.PL'
- pager location of external program more (or any pager)
- tar location of external program tar
- unzip location of external program unzip
- urllist arrayref to nearby CPAN sites (or equivalent locations)
- wait_list arrayref to a wait server to try (See CPAN::WAIT)
-
- You can set and query each of these options interactively in the cpan
- shell with the command set defined within the C<o conf> command:
-
- =over 2
-
- =item o conf E<lt>scalar optionE<gt>
-
- prints the current value of the I<scalar option>
-
- =item o conf E<lt>scalar optionE<gt> E<lt>valueE<gt>
-
- Sets the value of the I<scalar option> to I<value>
-
- =item o conf E<lt>list optionE<gt>
-
- prints the current value of the I<list option> in MakeMaker's
- neatvalue format.
-
- =item o conf E<lt>list optionE<gt> [shift|pop]
-
- shifts or pops the array in the I<list option> variable
-
- =item o conf E<lt>list optionE<gt> [unshift|push|splice] E<lt>listE<gt>
-
- works like the corresponding perl commands.

- =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
- install foreign, unmasked, unsigned code on your machine. We compare
- 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
- development will go towards strong authentification.
-
- =head1 EXPORT
-
- Most functions in package CPAN are exported per default. The reason
- for this is that the primary use is intended for the cpan shell or for
- oneliners.
-
- =head1 BUGS
-
- We should give coverage for _all_ of the CPAN and not just the PAUSE
- part, right? In this discussion CPAN and PAUSE have become equal --
- but they are not. PAUSE is authors/ and modules/. CPAN is PAUSE plus
- the clpa/, doc/, misc/, ports/, src/, scripts/.
-
- Future development should be directed towards a better integration of
- the other parts.
-
- If a Makefile.PL requires special customization of libraries, prompts
- the user for special input, etc. then you may find CPAN is not able to
- build the distribution. In that case, you should attempt the
- traditional method of building a Perl module package from a shell.
