=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 STATUS
This module will eventually be replaced by CPANPLUS. CPANPLUS is kind
of a modern rewrite from ground up with greater extensibility and more
features but no full compatibility. If you're new to CPAN.pm, you
probably should investigate if CPANPLUS is the better choice for you.
If you're already used to CPAN.pm you're welcome to continue using it,
if you accept that its development is mostly (though not completely)
stalled.
=head1 DESCRIPTION
The CPAN module is designed to automate the make and install of perl
modules and extensions. It includes some primitive 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
I<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.
For extended searching capabilities there's a plugin for CPAN available,
L<C<CPAN::WAIT>|CPAN::WAIT>. C<CPAN::WAIT> is a full-text search engine
that indexes all documents available in CPAN authors directories. If
C<CPAN::WAIT> is installed on your system, the interactive shell of
CPAN.pm will enable the C<wq>, C<wr>, C<wd>, C<wl>, and C<wh> commands
which send queries to the WAIT server that has been configured for your
installation.
All other 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 function call C<shell> takes two optional arguments, one is the
prompt, the second is the default initial command line (the latter
only works if a real ReadLine interface module is installed).
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 with the rather verbose method C<as_string>, but if we find
more than one, we display each object with the terse method
<as_glimpse>.
=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, following any dependencies named in
the module's Makefile.PL (this behavior is controlled by
I<prerequisites_policy>.)
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 doesn't need to be updated.
CPAN also 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 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 get, readme, look module or distribution
C<get> downloads a distribution file without further action. C<readme>
displays the README file of the associated distribution. 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 ls author
C<ls> lists all distribution files in and below an author's CPAN
directory. Only those files that contain modules are listed and if
there is more than one for any given module, only the most recent one
is listed.
=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 you'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
module version number which will also be reflected in the distribution
name when you run 'make dist'), so the really hottest and newest
distribution 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 Programmer'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>) also return 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 expandany(@things)
Like expand, but returns objects of the appropriate type, i.e.
CPAN::Bundle objects for bundles, CPAN::Module objects for modules and
CPAN::Distribution objects fro distributions.
=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 Digest::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";
}
# find out which distribution on CPAN contains a module:
print CPAN::Shell->expand("Module","Apache::Constants")->cpan_file
Or if you want to write a cronjob to watch The CPAN, you could list
all modules that need updating. First a quick and dirty way:
perl -e 'use CPAN; CPAN::Shell->r;'
If you don't want to get any output in the case that all modules are
up to date, you can parse the output of above command for the regular
expression //modules are up to date// and decide to mail the output
only if it doesn't match. Ick?
If you prefer to do it more in a programmer style in one single
process, maybe something like this suits you better:
# list all modules on my disk that have newer versions on CPAN
for $mod (CPAN::Shell->expand("Module","/./")){
next unless $mod->inst_file;
next if $mod->uptodate;
printf "Module %s is installed as %s, could be updated to %s from CPAN\n",
$mod->id, $mod->inst_version, $mod->cpan_version;
}
If that gives you too much output every day, you maybe only want to
watch for three modules. You can write
for $mod (CPAN::Shell->expand("Module","/Apache|LWP|CGI/")){
as the first line instead. Or you can combine some of the above
tricks:
# watch only for a new mod_perl module
$mod = CPAN::Shell->expand("Module","mod_perl");
exit if $mod->uptodate;
# new mod_perl arrived, let me know all update recommendations
CPAN::Shell->r;

=head2 Methods in the other Classes
The programming interface for the classes CPAN::Module,
CPAN::Distribution, CPAN::Bundle, and CPAN::Author is still considered
beta and partially even alpha. In the following paragraphs only those
methods are documented that have proven useful over a longer time and
thus are unlikely to change.
=over 4
=item CPAN::Author::as_glimpse()
Returns a one-line description of the author
=item CPAN::Author::as_string()
Returns a multi-line description of the author
=item CPAN::Author::email()
Returns the author's email address
=item CPAN::Author::fullname()
Returns the author's name
=item CPAN::Author::name()
An alias for fullname
=item CPAN::Bundle::as_glimpse()

=item CPAN::Bundle::as_string()
Returns a multi-line description of the bundle
=item CPAN::Bundle::clean()
Recursively runs the C<clean> method on all items contained in the bundle.
=item CPAN::Bundle::contains()
Returns a list of objects' IDs contained in a bundle. The associated
objects may be bundles, modules or distributions.
=item CPAN::Bundle::force($method,@args)
Forces CPAN to perform a task that normally would have failed. Force
takes as arguments a method name to be called and any number of
additional arguments that should be passed to the called method. The
internals of the object get the needed changes so that CPAN.pm does
not refuse to take the action. The C<force> is passed recursively to
all contained objects.
=item CPAN::Bundle::get()
Recursively runs the C<get> method on all items contained in the bundle
=item CPAN::Bundle::inst_file()
Returns the highest installed version of the bundle in either @INC or
C<$CPAN::Config->{cpan_home}>. Note that this is different from
CPAN::Module::inst_file.
=item CPAN::Bundle::inst_version()
Like CPAN::Bundle::inst_file, but returns the $VERSION
=item CPAN::Bundle::uptodate()
Returns 1 if the bundle itself and all its members are uptodate.
=item CPAN::Bundle::install()
Recursively runs the C<install> method on all items contained in the bundle
=item CPAN::Bundle::make()

=item CPAN::Distribution::as_string()
Returns a multi-line description of the distribution
=item CPAN::Distribution::clean()
Changes to the directory where the distribution has been unpacked and
runs C<make clean> there.
=item CPAN::Distribution::containsmods()
Returns a list of IDs of modules contained in a distribution file.
Only works for distributions listed in the 02packages.details.txt.gz
file. This typically means that only the most recent version of a
distribution is covered.
=item CPAN::Distribution::cvs_import()
Changes to the directory where the distribution has been unpacked and
runs something like
cvs -d $cvs_root import -m $cvs_log $cvs_dir $userid v$version
there.
=item CPAN::Distribution::dir()
Returns the directory into which this distribution has been unpacked.
=item CPAN::Distribution::force($method,@args)
Forces CPAN to perform a task that normally would have failed. Force
takes as arguments a method name to be called and any number of
additional arguments that should be passed to the called method. The
internals of the object get the needed changes so that CPAN.pm does
not refuse to take the action.
=item CPAN::Distribution::get()
Downloads the distribution from CPAN and unpacks it. Does nothing if
the distribution has already been downloaded and unpacked within the
current session.
=item CPAN::Distribution::install()
Changes to the directory where the distribution has been unpacked and
runs the external command C<make install> there. If C<make> has not
yet been run, it will be run first. A C<make test> will be issued in
any case and if this fails, the install will be canceled. The
cancellation can be avoided by letting C<force> run the C<install> for
you.
=item CPAN::Distribution::isa_perl()
Returns 1 if this distribution file seems to be a perl distribution.
Normally this is derived from the file name only, but the index from
CPAN can contain a hint to achieve a return value of true for other
filenames too.
=item CPAN::Distribution::look()
Changes to the directory where the distribution has been unpacked and
opens a subshell there. Exiting the subshell returns.
=item CPAN::Distribution::make()
First runs the C<get> method to make sure the distribution is
downloaded and unpacked. Changes to the directory where the
distribution has been unpacked and runs the external commands C<perl
Makefile.PL> and C<make> there.
=item CPAN::Distribution::prereq_pm()
Returns the hash reference that has been announced by a distribution
as the PREREQ_PM hash in the Makefile.PL. Note: works only after an
attempt has been made to C<make> the distribution. Returns undef
otherwise.
=item CPAN::Distribution::readme()
Downloads the README file associated with a distribution and runs it
through the pager specified in C<$CPAN::Config->{pager}>.
=item CPAN::Distribution::test()
Changes to the directory where the distribution has been unpacked and
runs C<make test> there.
=item CPAN::Distribution::uptodate()
Returns 1 if all the modules contained in the distribution are
uptodate. Relies on containsmods.
=item CPAN::Index::force_reload()
Forces a reload of all indices.
=item CPAN::Index::reload()
Reloads all indices if they have been read more than
C<$CPAN::Config->{index_expire}> days.
=item CPAN::InfoObj::dump()
CPAN::Author, CPAN::Bundle, CPAN::Module, and CPAN::Distribution
inherit this method. It prints the data structure associated with an
object. Useful for debugging. Note: the data structure is considered
internal and thus subject to change without notice.
=item CPAN::Module::as_glimpse()
Returns a one-line description of the module
=item CPAN::Module::as_string()
Returns a multi-line description of the module
=item CPAN::Module::clean()
Runs a clean on the distribution associated with this module.
=item CPAN::Module::cpan_file()
Returns the filename on CPAN that is associated with the module.
=item CPAN::Module::cpan_version()

Returns a 44 character description of this module. Only available for
modules listed in The Module List (CPAN/modules/00modlist.long.html
or 00modlist.long.txt.gz)
=item CPAN::Module::force($method,@args)
Forces CPAN to perform a task that normally would have failed. Force
takes as arguments a method name to be called and any number of
additional arguments that should be passed to the called method. The
internals of the object get the needed changes so that CPAN.pm does
not refuse to take the action.
=item CPAN::Module::get()
Runs a get on the distribution associated with this module.
=item CPAN::Module::inst_file()
Returns the filename of the module found in @INC. The first file found
is reported just like perl itself stops searching @INC when it finds a
module.
=item CPAN::Module::inst_version()
Returns the version number of the module in readable format.
=item CPAN::Module::install()
Runs an C<install> on the distribution associated with this module.
=item CPAN::Module::look()
Changes to the directory where the distribution associated with this
module has been unpacked and opens a subshell there. Exiting the
subshell returns.
=item CPAN::Module::make()
Runs a C<make> on the distribution associated with this module.
=item CPAN::Module::manpage_headline()
If module is installed, peeks into the module's manpage, reads the
headline and returns it. Moreover, if the module has been downloaded
within this session, does the equivalent on the downloaded module even
if it is not installed.
=item CPAN::Module::readme()
Runs a C<readme> on the distribution associated with this module.
=item CPAN::Module::test()

=item CPAN::Module::userid()
Returns the author's ID of the module.
=back
=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 a 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(shift)' 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 a bit complex, 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.
For code debugging in interactive mode you can try "o debug" which
will list options for debugging the various parts of the code. You
should know that "o debug" has built-in completion support.
For data debugging there is the C<dump> command which takes the same
arguments as make/test/install and outputs the object's Data::Dumper
dump.
=head2 Floppy, Zip, Offline Mode
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. See also below the paragraph about CD-ROM support.
=head1 CONFIGURATION
When the CPAN module is used for the first time, a configuration
dialog tries to determine a couple of site specific options. The
result of the dialog is stored in a hash reference C< $CPAN::Config >
in a file CPAN/Config.pm.
The default values defined in the CPAN/Config.pm file can be
overridden in a user specific file: CPAN/MyConfig.pm. Such a file is
best placed in $HOME/.cpan/CPAN/MyConfig.pm, because $HOME/.cpan is
added to the search path of the CPAN module before the use() or
require() statements.
The configuration dialog can be started any time later again by
issueing the command C< o conf init > in the CPAN shell.
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
cache_metadata use serializer to cache metadata
cpan_home local directory reserved for this package
dontload_hash anonymous hash: modules in the keys will not be
loaded by the CPAN::has_inst() routine
gzip location of external program gzip
histfile file to maintain history between sessions
histsize maximum number of lines to keep in histfile
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_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)
prerequisites_policy
what to do if you are missing module prerequisites
('follow' automatically, 'ask' me, or 'ignore')
proxy_user username for accessing an authenticating proxy
proxy_pass password for accessing an authenticating proxy
scan_cache controls scanning of cache ('atstart' or 'never')
tar location of external program tar
term_is_latin if true internal UTF-8 is translated to ISO-8859-1
(and nonsense for characters outside latin range)
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)
ftp_proxy, } the three usual variables for configuring
http_proxy, } proxy requests. Both as CPAN::Config variables
no_proxy } and as environment variables configurable.
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 C<o conf E<lt>scalar optionE<gt>>
prints the current value of the I<scalar option>
=item C<o conf E<lt>scalar optionE<gt> E<lt>valueE<gt>>
Sets the value of the I<scalar option> to I<value>
=item C<o conf E<lt>list optionE<gt>>
prints the current value of the I<list option> in MakeMaker's
neatvalue format.
=item C<o conf E<lt>list optionE<gt> [shift|pop]>
shifts or pops the array in the I<list option> variable
=item C<o conf E<lt>list optionE<gt> [unshift|push|splice] E<lt>listE<gt>>
works like the corresponding perl commands.
=back
=head2 Note on urllist parameter's format
urllist parameters are URLs according to RFC 1738. We do a little
guessing if your URL is not compliant, but if you have problems with
file URLs, please try the correct format. Either:
file://localhost/whatever/ftp/pub/CPAN/
or
file:///home/ftp/pub/CPAN/
=head2 urllist parameter has 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.
Another peculiarity of urllist is that the site that we could
successfully fetch the last file from automatically gets a preference
token and is tried as the first site for the next request. So if you
add a new site at runtime it may happen that the previously preferred
site will be tried another time. This means that if you want to disallow
a site for the next transfer, it must be explicitly removed from
urllist.
=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 authentication.
=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
one-liners.
=head1 POPULATE AN INSTALLATION WITH LOTS OF MODULES
Populating a freshly installed perl with my favorite modules is pretty
easy if you maintain a private bundle definition file. To get a useful
blueprint of a bundle definition file, the command autobundle can be used
on the CPAN shell command line. This command writes a bundle definition
file for all modules that are installed for the currently running perl
interpreter. It's recommended to run this command only once and from then
on maintain the file manually under a private name, say
Bundle/my_bundle.pm. With a clever bundle file you can then simply say
cpan> install Bundle::my_bundle
then answer a few questions and then go out for a coffee.
Maintaining a bundle definition file means keeping track of two
things: dependencies and interactivity. CPAN.pm sometimes fails on
calculating dependencies because not all modules define all MakeMaker
attributes correctly, so a bundle definition file should specify
prerequisites as early as possible. On the other hand, it's a bit
annoying that many distributions need some interactive configuring. So
what I try to accomplish in my private bundle file is to have the
packages that need to be configured early in the file and the gentle
ones later, so I can go out after a few minutes and leave CPAN.pm
untended.
=head1 WORKING WITH CPAN.pm BEHIND FIREWALLS
Thanks to Graham Barr for contributing the following paragraphs about
the interaction between perl, and various firewall configurations. For
further informations on firewalls, it is recommended to consult the
documentation that comes with the ncftp program. If you are unable to
go through the firewall with a simple Perl setup, it is very likely
that you can configure ncftp so that it works for your firewall.
=head2 Three basic types of firewalls
Firewalls can be categorized into three basic types.
=over 4
=item http firewall
This is where the firewall machine runs a web server and to access the
outside world you must do it via the web server. If you set environment
variables like http_proxy or ftp_proxy to a values beginning with http://
or in your web browser you have to set proxy information then you know
you are running an http firewall.
To access servers outside these types of firewalls with perl (even for
ftp) you will need to use LWP.
=item ftp firewall
This where the firewall machine runs an ftp server. This kind of
firewall will only let you access ftp servers outside the firewall.
This is usually done by connecting to the firewall with ftp, then
entering a username like "user@outside.host.com"
To access servers outside these type of firewalls with perl you
will need to use Net::FTP.
=item One way visibility
I say one way visibility as these firewalls try to make themselves look
invisible to the users inside the firewall. An FTP data connection is
normally created by sending the remote server your IP address and then
listening for the connection. But the remote server will not be able to
connect to you because of the firewall. So for these types of firewall
FTP connections need to be done in a passive mode.
There are two that I can think off.
=over 4
=item SOCKS
If you are using a SOCKS firewall you will need to compile perl and link
it with the SOCKS library, this is what is normally called a 'socksified'
perl. With this executable you will be able to connect to servers outside
the firewall as if it is not there.
=item IP Masquerade
This is the firewall implemented in the Linux kernel, it allows you to
hide a complete network behind one IP address. With this firewall no
special compiling is needed as you can access hosts directly.
For accessing ftp servers behind such firewalls you may need to set
the environment variable C<FTP_PASSIVE> to a true value, e.g.
env FTP_PASSIVE=1 perl -MCPAN -eshell
or
perl -MCPAN -e '$ENV{FTP_PASSIVE} = 1; shell'
=back
=back
=head2 Configuring lynx or ncftp for going through a firewall
If you can go through your firewall with e.g. lynx, presumably with a
command such as
/usr/local/bin/lynx -pscott:tiger
then you would configure CPAN.pm with the command
o conf lynx "/usr/local/bin/lynx -pscott:tiger"
That's all. Similarly for ncftp or ftp, you would configure something
like
o conf ncftp "/usr/bin/ncftp -f /home/scott/ncftplogin.cfg"
Your mileage may vary...
=head1 FAQ
=over 4
=item 1)
I installed a new version of module X but CPAN keeps saying,
I have the old version installed
Most probably you B<do> have the old version installed. This can
happen if a module installs itself into a different directory in the
@INC path than it was previously installed. This is not really a
CPAN.pm problem, you would have the same problem when installing the
module manually. The easiest way to prevent this behaviour is to add
the argument C<UNINST=1> to the C<make install> call, and that is why
many people add this argument permanently by configuring
o conf make_install_arg UNINST=1
=item 2)
So why is UNINST=1 not the default?
Because there are people who have their precise expectations about who
may install where in the @INC path and who uses which @INC array. In
fine tuned environments C<UNINST=1> can cause damage.
=item 3)
I want to clean up my mess, and install a new perl along with
all modules I have. How do I go about it?
Run the autobundle command for your old perl and optionally rename the
resulting bundle file (e.g. Bundle/mybundle.pm), install the new perl
with the Configure option prefix, e.g.
./Configure -Dprefix=/usr/local/perl-5.6.78.9
Install the bundle file you produced in the first step with something like
cpan> install Bundle::mybundle
and you're done.
=item 4)
When I install bundles or multiple modules with one command
there is too much output to keep track of.
You may want to configure something like
o conf make_arg "| tee -ai /root/.cpan/logs/make.out"
o conf make_install_arg "| tee -ai /root/.cpan/logs/make_install.out"
so that STDOUT is captured in a file for later inspection.
=item 5)
I am not root, how can I install a module in a personal directory?
You will most probably like something like this:
o conf makepl_arg "LIB=~/myperl/lib \
INSTALLMAN1DIR=~/myperl/man/man1 \
INSTALLMAN3DIR=~/myperl/man/man3"
install Sybase::Sybperl
You can make this setting permanent like all C<o conf> settings with
C<o conf commit>.
You will have to add ~/myperl/man to the MANPATH environment variable
and also tell your perl programs to look into ~/myperl/lib, e.g. by
including
use lib "$ENV{HOME}/myperl/lib";
or setting the PERL5LIB environment variable.
Another thing you should bear in mind is that the UNINST parameter
should never be set if you are not root.
=item 6)
How to get a package, unwrap it, and make a change before building it?
look Sybase::Sybperl
=item 7)
I installed a Bundle and had a couple of fails. When I
retried, everything resolved nicely. Can this be fixed to work
on first try?
The reason for this is that CPAN does not know the dependencies of all
modules when it starts out. To decide about the additional items to
install, it just uses data found in the generated Makefile. An
undetected missing piece breaks the process. But it may well be that
your Bundle installs some prerequisite later than some depending item
and thus your second try is able to resolve everything. Please note,
CPAN.pm does not know the dependency tree in advance and cannot sort
the queue of things to install in a topologically correct order. It
resolves perfectly well IFF all modules declare the prerequisites
correctly with the PREREQ_PM attribute to MakeMaker. For bundles which
fail and you need to install often, it is recommended sort the Bundle
definition file manually. It is planned to improve the metadata
situation for dependencies on CPAN in general, but this will still
take some time.
=item 8)
In our intranet we have many modules for internal use. How
can I integrate these modules with CPAN.pm but without uploading
the modules to CPAN?
Have a look at the CPAN::Site module.
=item 9)
When I run CPAN's shell, I get error msg about line 1 to 4,
setting meta input/output via the /etc/inputrc file.
Some versions of readline are picky about capitalization in the
/etc/inputrc file and specifically RedHat 6.2 comes with a
/etc/inputrc that contains the word C<on> in lowercase. Change the
occurrences of C<on> to C<On> and the bug should disappear.

Some authors have strange characters in their names.
Internally CPAN.pm uses the UTF-8 charset. If your terminal is
expecting ISO-8859-1 charset, a converter can be activated by setting
term_is_latin to a true value in your config file. One way of doing so
would be
cpan> ! $CPAN::Config->{term_is_latin}=1
Extended support for converters will be made available as soon as perl
becomes stable with regard to charset issues.

=head1 BUGS
We should give coverage for B<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/, modules/ and scripts/. CPAN is
PAUSE plus the clpa/, doc/, misc/, ports/, and src/.
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.
