344 # announce the availability of a new CPAN module
346 # Now we try to use it for dependency tracking. For that to happen
347 # we need to draw a dependency tree and do the leaves first. This can
348 # easily be reached by running CPAN.pm recursively, but we don't want
349 # to waste memory and run into deep recursion. So what we can do is
352 # CPAN::Queue is the package where the queue is maintained. Dependencies
353 # often have high priority and must be brought to the head of the queue,
354 # possibly by jumping the queue if they are already there. My first code
355 # attempt tried to be extremely correct. Whenever a module needed
356 # immediate treatment, I either unshifted it to the front of the queue,
357 # or, if it was already in the queue, I spliced and let it bypass the
358 # others. This became a too correct model that made it impossible to put
359 # an item more than once into the queue. Why would you need that? Well,
360 # you need temporary duplicates as the manager of the queue is a loop
363 # (1) looks at the first item in the queue without shifting it off
365 # (2) cares for the item
367 # (3) removes the item from the queue, *even if its agenda failed and
368 # even if the item isn't the first in the queue anymore* (that way
369 # protecting against never ending queues)
371 # So if an item has prerequisites, the installation fails now, but we
372 # want to retry later. That's easy if we have it twice in the queue.
374 # I also expect insane dependency situations where an item gets more
375 # than two lives in the queue. Simplest example is triggered by 'install
376 # Foo Foo Foo'. People make this kind of mistakes and I don't want to
377 # get in the way. I wanted the queue manager to be a dumb servant, not
378 # one that knows everything.
380 # Who would I tell in this model that the user wants to be asked before
381 # processing? I can't attach that information to the module object,
382 # because not modules are installed but distributions. So I'd have to
383 # tell the distribution object that it should ask the user before
384 # processing. Where would the question be triggered then? Most probably
385 # in CPAN::Distribution::rematein.

5982 CPAN - query, download and build perl modules from CPAN sites
5988 perl -MCPAN -e shell;
5994 autobundle, clean, install, make, recompile, test
5998 This module will eventually be replaced by CPANPLUS. CPANPLUS is kind
5999 of a modern rewrite from ground up with greater extensibility and more
6000 features but no full compatibility. If you're new to CPAN.pm, you
6001 probably should investigate if CPANPLUS is the better choice for you.
6002 If you're already used to CPAN.pm you're welcome to continue using it,
6003 if you accept that its development is mostly (though not completely)
6008 The CPAN module is designed to automate the make and install of perl
6009 modules and extensions. It includes some primitive searching capabilities and
6010 knows how to use Net::FTP or LWP (or lynx or an external ftp client)
6011 to fetch the raw data from the net.
6013 Modules are fetched from one or more of the mirrored CPAN
6014 (Comprehensive Perl Archive Network) sites and unpacked in a dedicated
6017 The CPAN module also supports the concept of named and versioned
6018 I<bundles> of modules. Bundles simplify the handling of sets of
6019 related modules. See Bundles below.
6021 The package contains a session manager and a cache manager. There is
6022 no status retained between sessions. The session manager keeps track
6023 of what has been fetched, built and installed in the current
6024 session. The cache manager keeps track of the disk space occupied by
6025 the make processes and deletes excess space according to a simple FIFO
6028 For extended searching capabilities there's a plugin for CPAN available,
6029 L<C<CPAN::WAIT>|CPAN::WAIT>. C<CPAN::WAIT> is a full-text search engine
6030 that indexes all documents available in CPAN authors directories. If
6031 C<CPAN::WAIT> is installed on your system, the interactive shell of
6032 CPAN.pm will enable the C<wq>, C<wr>, C<wd>, C<wl>, and C<wh> commands
6033 which send queries to the WAIT server that has been configured for your
6036 All other methods provided are accessible in a programmer style and in an
6037 interactive shell style.
6039 =head2 Interactive Mode
6041 The interactive mode is entered by running
6043 perl -MCPAN -e shell
6045 which puts you into a readline interface. You will have the most fun if
6046 you install Term::ReadKey and Term::ReadLine to enjoy both history and
6049 Once you are on the command line, type 'h' and the rest should be
6052 The function call C<shell> takes two optional arguments, one is the
6053 prompt, the second is the default initial command line (the latter
6054 only works if a real ReadLine interface module is installed).
6056 The most common uses of the interactive modes are
6060 =item Searching for authors, bundles, distribution files and modules
6062 There are corresponding one-letter commands C<a>, C<b>, C<d>, and C<m>
6063 for each of the four categories and another, C<i> for any of the
6064 mentioned four. Each of the four entities is implemented as a class
6065 with slightly differing methods for displaying an object.
6067 Arguments you pass to these commands are either strings exactly matching
6068 the identification string of an object or regular expressions that are
6069 then matched case-insensitively against various attributes of the
6070 objects. The parser recognizes a regular expression only if you
6071 enclose it between two slashes.
6073 The principle is that the number of found objects influences how an
6074 item is displayed. If the search finds one item, the result is
6075 displayed with the rather verbose method C<as_string>, but if we find
6076 more than one, we display each object with the terse method
6079 =item make, test, install, clean modules or distributions
6081 These commands take any number of arguments and investigate what is
6082 necessary to perform the action. If the argument is a distribution
6083 file name (recognized by embedded slashes), it is processed. If it is
6084 a module, CPAN determines the distribution file in which this module
6085 is included and processes that, following any dependencies named in
6086 the module's Makefile.PL (this behavior is controlled by
6087 I<prerequisites_policy>.)
6089 Any C<make> or C<test> are run unconditionally. An
6091 install <distribution_file>
6093 also is run unconditionally. But for
6097 CPAN checks if an install is actually needed for it and prints
6098 I<module up to date> in the case that the distribution file containing
6099 the module doesn't need to be updated.
6101 CPAN also keeps track of what it has done within the current session
6102 and doesn't try to build a package a second time regardless if it
6103 succeeded or not. The C<force> command takes as a first argument the
6104 method to invoke (currently: C<make>, C<test>, or C<install>) and executes the
6105 command from scratch.
6109 cpan> install OpenGL
6110 OpenGL is up to date.
6111 cpan> force install OpenGL
6114 OpenGL-0.4/COPYRIGHT
6117 A C<clean> command results in a
6121 being executed within the distribution file's working directory.
6123 =item get, readme, look module or distribution
6125 C<get> downloads a distribution file without further action. C<readme>
6126 displays the README file of the associated distribution. C<Look> gets
6127 and untars (if not yet done) the distribution file, changes to the
6128 appropriate directory and opens a subshell process in that directory.
6132 C<ls> lists all distribution files in and below an author's CPAN
6133 directory. Only those files that contain modules are listed and if
6134 there is more than one for any given module, only the most recent one
6139 CPAN.pm installs signal handlers for SIGINT and SIGTERM. While you are
6140 in the cpan-shell it is intended that you can press C<^C> anytime and
6141 return to the cpan-shell prompt. A SIGTERM will cause the cpan-shell
6142 to clean up and leave the shell loop. You can emulate the effect of a
6143 SIGTERM by sending two consecutive SIGINTs, which usually means by
6144 pressing C<^C> twice.
6146 CPAN.pm ignores a SIGPIPE. If the user sets inactivity_timeout, a
6147 SIGALRM is used during the run of the C<perl Makefile.PL> subprocess.
6153 The commands that are available in the shell interface are methods in
6154 the package CPAN::Shell. If you enter the shell command, all your
6155 input is split by the Text::ParseWords::shellwords() routine which
6156 acts like most shells do. The first word is being interpreted as the
6157 method to be called and the rest of the words are treated as arguments
6158 to this method. Continuation lines are supported if a line ends with a
6163 C<autobundle> writes a bundle file into the
6164 C<$CPAN::Config-E<gt>{cpan_home}/Bundle> directory. The file contains
6165 a list of all modules that are both available from CPAN and currently
6166 installed within @INC. The name of the bundle file is based on the
6167 current date and a counter.
6171 recompile() is a very special command in that it takes no argument and
6172 runs the make/test/install cycle with brute force over all installed
6173 dynamically loadable extensions (aka XS modules) with 'force' in
6174 effect. The primary purpose of this command is to finish a network
6175 installation. Imagine, you have a common source tree for two different
6176 architectures. You decide to do a completely independent fresh
6177 installation. You start on one architecture with the help of a Bundle
6178 file produced earlier. CPAN installs the whole Bundle for you, but
6179 when you try to repeat the job on the second architecture, CPAN
6180 responds with a C<"Foo up to date"> message for all modules. So you
6181 invoke CPAN's recompile on the second architecture and you're done.
6183 Another popular use for C<recompile> is to act as a rescue in case your
6184 perl breaks binary compatibility. If one of the modules that CPAN uses
6185 is in turn depending on binary compatibility (so you cannot run CPAN
6186 commands), then you should try the CPAN::Nox module for recovery.
6188 =head2 The four C<CPAN::*> Classes: Author, Bundle, Module, Distribution
6190 Although it may be considered internal, the class hierarchy does matter
6191 for both users and programmer. CPAN.pm deals with above mentioned four
6192 classes, and all those classes share a set of methods. A classical
6193 single polymorphism is in effect. A metaclass object registers all
6194 objects of all kinds and indexes them with a string. The strings
6195 referencing objects have a separated namespace (well, not completely
6200 words containing a "/" (slash) Distribution
6201 words starting with Bundle:: Bundle
6202 everything else Module or Author
6204 Modules know their associated Distribution objects. They always refer
6205 to the most recent official release. Developers may mark their releases
6206 as unstable development versions (by inserting an underbar into the
6207 module version number which will also be reflected in the distribution
6208 name when you run 'make dist'), so the really hottest and newest
6209 distribution is not always the default. If a module Foo circulates
6210 on CPAN in both version 1.23 and 1.23_90, CPAN.pm offers a convenient
6211 way to install version 1.23 by saying
6215 This would install the complete distribution file (say
6216 BAR/Foo-1.23.tar.gz) with all accompanying material. But if you would
6217 like to install version 1.23_90, you need to know where the
6218 distribution file resides on CPAN relative to the authors/id/
6219 directory. If the author is BAR, this might be BAR/Foo-1.23_90.tar.gz;
6220 so you would have to say
6222 install BAR/Foo-1.23_90.tar.gz
6224 The first example will be driven by an object of the class
6225 CPAN::Module, the second by an object of class CPAN::Distribution.
6227 =head2 Programmer's interface
6229 If you do not enter the shell, the available shell commands are both
6230 available as methods (C<CPAN::Shell-E<gt>install(...)>) and as
6231 functions in the calling package (C<install(...)>).
6233 There's currently only one class that has a stable interface -
6234 CPAN::Shell. All commands that are available in the CPAN shell are
6235 methods of the class CPAN::Shell. Each of the commands that produce
6236 listings of modules (C<r>, C<autobundle>, C<u>) also return a list of
6237 the IDs of all modules within the list.
6241 =item expand($type,@things)
6243 The IDs of all objects available within a program are strings that can
6244 be expanded to the corresponding real objects with the
6245 C<CPAN::Shell-E<gt>expand("Module",@things)> method. Expand returns a
6246 list of CPAN::Module objects according to the C<@things> arguments
6247 given. In scalar context it only returns the first element of the
6250 =item expandany(@things)
6252 Like expand, but returns objects of the appropriate type, i.e.
6253 CPAN::Bundle objects for bundles, CPAN::Module objects for modules and
6254 CPAN::Distribution objects fro distributions.
6256 =item Programming Examples
6258 This enables the programmer to do operations that combine
6259 functionalities that are available in the shell.
6261 # install everything that is outdated on my disk:
6262 perl -MCPAN -e 'CPAN::Shell->install(CPAN::Shell->r)'
6264 # install my favorite programs if necessary:
6265 for $mod (qw(Net::FTP Digest::MD5 Data::Dumper)){
6266 my $obj = CPAN::Shell->expand('Module',$mod);
6270 # list all modules on my disk that have no VERSION number
6271 for $mod (CPAN::Shell->expand("Module","/./")){
6272 next unless $mod->inst_file;
6273 # MakeMaker convention for undefined $VERSION:
6274 next unless $mod->inst_version eq "undef";
6275 print "No VERSION in ", $mod->id, "\n";
6278 # find out which distribution on CPAN contains a module:
6279 print CPAN::Shell->expand("Module","Apache::Constants")->cpan_file
6281 Or if you want to write a cronjob to watch The CPAN, you could list
6282 all modules that need updating. First a quick and dirty way:
6284 perl -e 'use CPAN; CPAN::Shell->r;'
6286 If you don't want to get any output in the case that all modules are
6287 up to date, you can parse the output of above command for the regular
6288 expression //modules are up to date// and decide to mail the output
6289 only if it doesn't match. Ick?
6291 If you prefer to do it more in a programmer style in one single
6292 process, maybe something like this suits you better:
6294 # list all modules on my disk that have newer versions on CPAN
6295 for $mod (CPAN::Shell->expand("Module","/./")){
6296 next unless $mod->inst_file;
6297 next if $mod->uptodate;
6298 printf "Module %s is installed as %s, could be updated to %s from CPAN\n",
6299 $mod->id, $mod->inst_version, $mod->cpan_version;
6302 If that gives you too much output every day, you maybe only want to
6303 watch for three modules. You can write
6305 for $mod (CPAN::Shell->expand("Module","/Apache|LWP|CGI/")){
6307 as the first line instead. Or you can combine some of the above
6310 # watch only for a new mod_perl module
6311 $mod = CPAN::Shell->expand("Module","mod_perl");
6312 exit if $mod->uptodate;
6313 # new mod_perl arrived, let me know all update recommendations
6318 =head2 Methods in the other Classes
6320 The programming interface for the classes CPAN::Module,
6321 CPAN::Distribution, CPAN::Bundle, and CPAN::Author is still considered
6322 beta and partially even alpha. In the following paragraphs only those
6323 methods are documented that have proven useful over a longer time and
6324 thus are unlikely to change.
6328 =item CPAN::Author::as_glimpse()
6330 Returns a one-line description of the author
6332 =item CPAN::Author::as_string()
6334 Returns a multi-line description of the author
6336 =item CPAN::Author::email()
6338 Returns the author's email address
6340 =item CPAN::Author::fullname()
6342 Returns the author's name

6363 objects may be bundles, modules or distributions.
6365 =item CPAN::Bundle::force($method,@args)
6367 Forces CPAN to perform a task that normally would have failed. Force
6368 takes as arguments a method name to be called and any number of
6369 additional arguments that should be passed to the called method. The
6370 internals of the object get the needed changes so that CPAN.pm does
6371 not refuse to take the action. The C<force> is passed recursively to
6372 all contained objects.
6374 =item CPAN::Bundle::get()
6376 Recursively runs the C<get> method on all items contained in the bundle
6378 =item CPAN::Bundle::inst_file()
6380 Returns the highest installed version of the bundle in either @INC or
6381 C<$CPAN::Config->{cpan_home}>. Note that this is different from
6382 CPAN::Module::inst_file.
6384 =item CPAN::Bundle::inst_version()
6386 Like CPAN::Bundle::inst_file, but returns the $VERSION
6388 =item CPAN::Bundle::uptodate()
6390 Returns 1 if the bundle itself and all its members are uptodate.
6392 =item CPAN::Bundle::install()
6394 Recursively runs the C<install> method on all items contained in the bundle
6396 =item CPAN::Bundle::make()

6412 =item CPAN::Distribution::as_string()
6414 Returns a multi-line description of the distribution
6416 =item CPAN::Distribution::clean()
6418 Changes to the directory where the distribution has been unpacked and
6419 runs C<make clean> there.
6421 =item CPAN::Distribution::containsmods()
6423 Returns a list of IDs of modules contained in a distribution file.
6424 Only works for distributions listed in the 02packages.details.txt.gz
6425 file. This typically means that only the most recent version of a
6426 distribution is covered.
6428 =item CPAN::Distribution::cvs_import()
6430 Changes to the directory where the distribution has been unpacked and
6433 cvs -d $cvs_root import -m $cvs_log $cvs_dir $userid v$version
6437 =item CPAN::Distribution::dir()
6439 Returns the directory into which this distribution has been unpacked.
6441 =item CPAN::Distribution::force($method,@args)
6443 Forces CPAN to perform a task that normally would have failed. Force
6444 takes as arguments a method name to be called and any number of
6445 additional arguments that should be passed to the called method. The
6446 internals of the object get the needed changes so that CPAN.pm does
6447 not refuse to take the action.
6449 =item CPAN::Distribution::get()
6451 Downloads the distribution from CPAN and unpacks it. Does nothing if
6452 the distribution has already been downloaded and unpacked within the
6455 =item CPAN::Distribution::install()
6457 Changes to the directory where the distribution has been unpacked and
6458 runs the external command C<make install> there. If C<make> has not
6459 yet been run, it will be run first. A C<make test> will be issued in
6460 any case and if this fails, the install will be canceled. The
6461 cancellation can be avoided by letting C<force> run the C<install> for
6464 =item CPAN::Distribution::isa_perl()
6466 Returns 1 if this distribution file seems to be a perl distribution.
6467 Normally this is derived from the file name only, but the index from
6468 CPAN can contain a hint to achieve a return value of true for other
6471 =item CPAN::Distribution::look()
6473 Changes to the directory where the distribution has been unpacked and
6474 opens a subshell there. Exiting the subshell returns.
6476 =item CPAN::Distribution::make()
6478 First runs the C<get> method to make sure the distribution is
6479 downloaded and unpacked. Changes to the directory where the
6480 distribution has been unpacked and runs the external commands C<perl
6481 Makefile.PL> and C<make> there.
6483 =item CPAN::Distribution::prereq_pm()
6485 Returns the hash reference that has been announced by a distribution
6486 as the PREREQ_PM hash in the Makefile.PL. Note: works only after an
6487 attempt has been made to C<make> the distribution. Returns undef
6490 =item CPAN::Distribution::readme()
6492 Downloads the README file associated with a distribution and runs it
6493 through the pager specified in C<$CPAN::Config->{pager}>.
6495 =item CPAN::Distribution::test()
6497 Changes to the directory where the distribution has been unpacked and
6498 runs C<make test> there.
6500 =item CPAN::Distribution::uptodate()
6502 Returns 1 if all the modules contained in the distribution are
6503 uptodate. Relies on containsmods.
6505 =item CPAN::Index::force_reload()
6507 Forces a reload of all indices.
6509 =item CPAN::Index::reload()
6511 Reloads all indices if they have been read more than
6512 C<$CPAN::Config->{index_expire}> days.
6514 =item CPAN::InfoObj::dump()
6516 CPAN::Author, CPAN::Bundle, CPAN::Module, and CPAN::Distribution
6517 inherit this method. It prints the data structure associated with an
6518 object. Useful for debugging. Note: the data structure is considered
6519 internal and thus subject to change without notice.
6521 =item CPAN::Module::as_glimpse()
6523 Returns a one-line description of the module
6525 =item CPAN::Module::as_string()
6527 Returns a multi-line description of the module
6529 =item CPAN::Module::clean()
6531 Runs a clean on the distribution associated with this module.
6533 =item CPAN::Module::cpan_file()
6535 Returns the filename on CPAN that is associated with the module.
6537 =item CPAN::Module::cpan_version()
6539 Returns the latest version of this module available on CPAN.
6541 =item CPAN::Module::cvs_import()
6543 Runs a cvs_import on the distribution associated with this module.
6545 =item CPAN::Module::description()
6547 Returns a 44 character description of this module. Only available for
6548 modules listed in The Module List (CPAN/modules/00modlist.long.html
6549 or 00modlist.long.txt.gz)
6551 =item CPAN::Module::force($method,@args)
6553 Forces CPAN to perform a task that normally would have failed. Force
6554 takes as arguments a method name to be called and any number of
6555 additional arguments that should be passed to the called method. The
6556 internals of the object get the needed changes so that CPAN.pm does
6557 not refuse to take the action.
6559 =item CPAN::Module::get()
6561 Runs a get on the distribution associated with this module.
6563 =item CPAN::Module::inst_file()
6565 Returns the filename of the module found in @INC. The first file found
6566 is reported just like perl itself stops searching @INC when it finds a
6569 =item CPAN::Module::inst_version()
6571 Returns the version number of the module in readable format.
6573 =item CPAN::Module::install()
6575 Runs an C<install> on the distribution associated with this module.
6577 =item CPAN::Module::look()
6579 Changes to the directory where the distribution associated with this
6580 module has been unpacked and opens a subshell there. Exiting the
6583 =item CPAN::Module::make()
6585 Runs a C<make> on the distribution associated with this module.
6587 =item CPAN::Module::manpage_headline()
6589 If module is installed, peeks into the module's manpage, reads the
6590 headline and returns it. Moreover, if the module has been downloaded
6591 within this session, does the equivalent on the downloaded module even
6592 if it is not installed.
6594 =item CPAN::Module::readme()
6596 Runs a C<readme> on the distribution associated with this module.
6598 =item CPAN::Module::test()
6600 Runs a C<test> on the distribution associated with this module.
6602 =item CPAN::Module::uptodate()
6604 Returns 1 if the module is installed and up-to-date.
6606 =item CPAN::Module::userid()
6608 Returns the author's ID of the module.
6612 =head2 Cache Manager
6614 Currently the cache manager only keeps track of the build directory
6615 ($CPAN::Config->{build_dir}). It is a simple FIFO mechanism that
6616 deletes complete directories below C<build_dir> as soon as the size of
6617 all directories there gets bigger than $CPAN::Config->{build_cache}
6618 (in MB). The contents of this cache may be used for later
6619 re-installations that you intend to do manually, but will never be
6620 trusted by CPAN itself. This is due to the fact that the user might
6621 use these directories for building modules on different architectures.
6623 There is another directory ($CPAN::Config->{keep_source_where}) where
6624 the original distribution files are kept. This directory is not
6625 covered by the cache manager and must be controlled by the user. If
6626 you choose to have the same directory as build_dir and as
6627 keep_source_where directory, then your sources will be deleted with
6628 the same fifo mechanism.
6632 A bundle is just a perl module in the namespace Bundle:: that does not
6633 define any functions or methods. It usually only contains documentation.
6635 It starts like a perl module with a package declaration and a $VERSION
6636 variable. After that the pod section looks like any other pod with the
6637 only difference being that I<one special pod section> exists starting with
6642 In this pod section each line obeys the format
6644 Module_Name [Version_String] [- optional text]
6646 The only required part is the first field, the name of a module
6647 (e.g. Foo::Bar, ie. I<not> the name of the distribution file). The rest
6648 of the line is optional. The comment part is delimited by a dash just
6649 as in the man page header.
6651 The distribution of a bundle should follow the same convention as
6652 other distributions.
6654 Bundles are treated specially in the CPAN package. If you say 'install
6655 Bundle::Tkkit' (assuming such a bundle exists), CPAN will install all
6656 the modules in the CONTENTS section of the pod. You can install your
6657 own Bundles locally by placing a conformant Bundle file somewhere into
6658 your @INC path. The autobundle() command which is available in the
6659 shell interface does that for you by including all currently installed
6660 modules in a snapshot bundle file.
6662 =head2 Prerequisites
6664 If you have a local mirror of CPAN and can access all files with
6665 "file:" URLs, then you only need a perl better than perl5.003 to run
6666 this module. Otherwise Net::FTP is strongly recommended. LWP may be
6667 required for non-UNIX systems or if your nearest CPAN site is
6668 associated with a URL that is not C<ftp:>.
6670 If you have neither Net::FTP nor LWP, there is a fallback mechanism
6671 implemented for an external ftp command or for an external lynx
6674 =head2 Finding packages and VERSION
6676 This module presumes that all packages on CPAN
6682 declare their $VERSION variable in an easy to parse manner. This
6683 prerequisite can hardly be relaxed because it consumes far too much
6684 memory to load all packages into the running program just to determine
6685 the $VERSION variable. Currently all programs that are dealing with
6686 version use something like this
6688 perl -MExtUtils::MakeMaker -le \
6689 'print MM->parse_version(shift)' filename
6691 If you are author of a package and wonder if your $VERSION can be
6692 parsed, please try the above method.
6696 come as compressed or gzipped tarfiles or as zip files and contain a
6697 Makefile.PL (well, we try to handle a bit more, but without much
6704 The debugging of this module is a bit complex, because we have
6705 interferences of the software producing the indices on CPAN, of the
6706 mirroring process on CPAN, of packaging, of configuration, of
6707 synchronicity, and of bugs within CPAN.pm.
6709 For code debugging in interactive mode you can try "o debug" which
6710 will list options for debugging the various parts of the code. You
6711 should know that "o debug" has built-in completion support.
6713 For data debugging there is the C<dump> command which takes the same
6714 arguments as make/test/install and outputs the object's Data::Dumper
6717 =head2 Floppy, Zip, Offline Mode
6719 CPAN.pm works nicely without network too. If you maintain machines
6720 that are not networked at all, you should consider working with file:
6721 URLs. Of course, you have to collect your modules somewhere first. So
6722 you might use CPAN.pm to put together all you need on a networked
6723 machine. Then copy the $CPAN::Config->{keep_source_where} (but not
6724 $CPAN::Config->{build_dir}) directory on a floppy. This floppy is kind
6725 of a personal CPAN. CPAN.pm on the non-networked machines works nicely
6726 with this floppy. See also below the paragraph about CD-ROM support.
6728 =head1 CONFIGURATION
6730 When the CPAN module is used for the first time, a configuration
6731 dialog tries to determine a couple of site specific options. The
6732 result of the dialog is stored in a hash reference C< $CPAN::Config >
6733 in a file CPAN/Config.pm.
6735 The default values defined in the CPAN/Config.pm file can be
6736 overridden in a user specific file: CPAN/MyConfig.pm. Such a file is
6737 best placed in $HOME/.cpan/CPAN/MyConfig.pm, because $HOME/.cpan is
6738 added to the search path of the CPAN module before the use() or
6739 require() statements.
6741 The configuration dialog can be started any time later again by
6742 issueing the command C< o conf init > in the CPAN shell.
6744 Currently the following keys in the hash reference $CPAN::Config are
6747 build_cache size of cache for directories to build modules
6748 build_dir locally accessible directory to build modules
6749 index_expire after this many days refetch index files
6750 cache_metadata use serializer to cache metadata
6751 cpan_home local directory reserved for this package
6752 dontload_hash anonymous hash: modules in the keys will not be
6753 loaded by the CPAN::has_inst() routine
6754 gzip location of external program gzip
6755 histfile file to maintain history between sessions
6756 histsize maximum number of lines to keep in histfile
6757 inactivity_timeout breaks interactive Makefile.PLs after this
6758 many seconds inactivity. Set to 0 to never break.
6759 inhibit_startup_message
6760 if true, does not print the startup message
6761 keep_source_where directory in which to keep the source (if we do)
6762 make location of external make program
6763 make_arg arguments that should always be passed to 'make'
6764 make_install_arg same as make_arg for 'make install'
6765 makepl_arg arguments passed to 'perl Makefile.PL'
6766 pager location of external program more (or any pager)
6767 prerequisites_policy
6768 what to do if you are missing module prerequisites
6769 ('follow' automatically, 'ask' me, or 'ignore')
6770 proxy_user username for accessing an authenticating proxy
6771 proxy_pass password for accessing an authenticating proxy
6772 scan_cache controls scanning of cache ('atstart' or 'never')
6773 tar location of external program tar
6774 term_is_latin if true internal UTF-8 is translated to ISO-8859-1
6775 (and nonsense for characters outside latin range)
6776 unzip location of external program unzip
6777 urllist arrayref to nearby CPAN sites (or equivalent locations)
6778 wait_list arrayref to a wait server to try (See CPAN::WAIT)
6779 ftp_proxy, } the three usual variables for configuring
6780 http_proxy, } proxy requests. Both as CPAN::Config variables
6781 no_proxy } and as environment variables configurable.
6783 You can set and query each of these options interactively in the cpan
6784 shell with the command set defined within the C<o conf> command:
6788 =item C<o conf E<lt>scalar optionE<gt>>
6790 prints the current value of the I<scalar option>
6792 =item C<o conf E<lt>scalar optionE<gt> E<lt>valueE<gt>>
6794 Sets the value of the I<scalar option> to I<value>
6796 =item C<o conf E<lt>list optionE<gt>>
6798 prints the current value of the I<list option> in MakeMaker's
6801 =item C<o conf E<lt>list optionE<gt> [shift|pop]>
6803 shifts or pops the array in the I<list option> variable
6805 =item C<o conf E<lt>list optionE<gt> [unshift|push|splice] E<lt>listE<gt>>
6807 works like the corresponding perl commands.
6811 =head2 Note on urllist parameter's format
6813 urllist parameters are URLs according to RFC 1738. We do a little
6814 guessing if your URL is not compliant, but if you have problems with
6815 file URLs, please try the correct format. Either:
6817 file://localhost/whatever/ftp/pub/CPAN/
6821 file:///home/ftp/pub/CPAN/
6823 =head2 urllist parameter has CD-ROM support
6825 The C<urllist> parameter of the configuration table contains a list of
6826 URLs that are to be used for downloading. If the list contains any
6827 C<file> URLs, CPAN always tries to get files from there first. This
6828 feature is disabled for index files. So the recommendation for the
6829 owner of a CD-ROM with CPAN contents is: include your local, possibly
6830 outdated CD-ROM as a C<file> URL at the end of urllist, e.g.
6832 o conf urllist push file://localhost/CDROM/CPAN
6834 CPAN.pm will then fetch the index files from one of the CPAN sites
6835 that come at the beginning of urllist. It will later check for each
6836 module if there is a local copy of the most recent version.
6838 Another peculiarity of urllist is that the site that we could
6839 successfully fetch the last file from automatically gets a preference
6840 token and is tried as the first site for the next request. So if you
6841 add a new site at runtime it may happen that the previously preferred
6842 site will be tried another time. This means that if you want to disallow
6843 a site for the next transfer, it must be explicitly removed from
6848 There's no strong security layer in CPAN.pm. CPAN.pm helps you to
6849 install foreign, unmasked, unsigned code on your machine. We compare
6850 to a checksum that comes from the net just as the distribution file
6851 itself. If somebody has managed to tamper with the distribution file,
6852 they may have as well tampered with the CHECKSUMS file. Future
6853 development will go towards strong authentication.
6857 Most functions in package CPAN are exported per default. The reason
6858 for this is that the primary use is intended for the cpan shell or for
6861 =head1 POPULATE AN INSTALLATION WITH LOTS OF MODULES
6863 Populating a freshly installed perl with my favorite modules is pretty
6864 easy if you maintain a private bundle definition file. To get a useful
6865 blueprint of a bundle definition file, the command autobundle can be used
6866 on the CPAN shell command line. This command writes a bundle definition
6867 file for all modules that are installed for the currently running perl
6868 interpreter. It's recommended to run this command only once and from then
6869 on maintain the file manually under a private name, say
6870 Bundle/my_bundle.pm. With a clever bundle file you can then simply say
6872 cpan> install Bundle::my_bundle
6874 then answer a few questions and then go out for a coffee.
6876 Maintaining a bundle definition file means keeping track of two
6877 things: dependencies and interactivity. CPAN.pm sometimes fails on
6878 calculating dependencies because not all modules define all MakeMaker
6879 attributes correctly, so a bundle definition file should specify
6880 prerequisites as early as possible. On the other hand, it's a bit
6881 annoying that many distributions need some interactive configuring. So
6882 what I try to accomplish in my private bundle file is to have the
6883 packages that need to be configured early in the file and the gentle
6884 ones later, so I can go out after a few minutes and leave CPAN.pm
6887 =head1 WORKING WITH CPAN.pm BEHIND FIREWALLS
6889 Thanks to Graham Barr for contributing the following paragraphs about
6890 the interaction between perl, and various firewall configurations. For
6891 further informations on firewalls, it is recommended to consult the
6892 documentation that comes with the ncftp program. If you are unable to
6893 go through the firewall with a simple Perl setup, it is very likely
6894 that you can configure ncftp so that it works for your firewall.
6896 =head2 Three basic types of firewalls
6898 Firewalls can be categorized into three basic types.
6904 This is where the firewall machine runs a web server and to access the
6905 outside world you must do it via the web server. If you set environment
6906 variables like http_proxy or ftp_proxy to a values beginning with http://
6907 or in your web browser you have to set proxy information then you know
6908 you are running an http firewall.
6910 To access servers outside these types of firewalls with perl (even for
6911 ftp) you will need to use LWP.
6915 This where the firewall machine runs an ftp server. This kind of
6916 firewall will only let you access ftp servers outside the firewall.
6917 This is usually done by connecting to the firewall with ftp, then
6918 entering a username like "user@outside.host.com"
6920 To access servers outside these type of firewalls with perl you
6921 will need to use Net::FTP.
6923 =item One way visibility
6925 I say one way visibility as these firewalls try to make themselves look
6926 invisible to the users inside the firewall. An FTP data connection is
6927 normally created by sending the remote server your IP address and then
6928 listening for the connection. But the remote server will not be able to
6929 connect to you because of the firewall. So for these types of firewall
6930 FTP connections need to be done in a passive mode.
6932 There are two that I can think off.
6938 If you are using a SOCKS firewall you will need to compile perl and link
6939 it with the SOCKS library, this is what is normally called a 'socksified'
6940 perl. With this executable you will be able to connect to servers outside
6941 the firewall as if it is not there.
6945 This is the firewall implemented in the Linux kernel, it allows you to
6946 hide a complete network behind one IP address. With this firewall no
6947 special compiling is needed as you can access hosts directly.
6949 For accessing ftp servers behind such firewalls you may need to set
6950 the environment variable C<FTP_PASSIVE> to a true value, e.g.
6952 env FTP_PASSIVE=1 perl -MCPAN -eshell
6956 perl -MCPAN -e '$ENV{FTP_PASSIVE} = 1; shell'
6963 =head2 Configuring lynx or ncftp for going through a firewall
6965 If you can go through your firewall with e.g. lynx, presumably with a
6968 /usr/local/bin/lynx -pscott:tiger
6970 then you would configure CPAN.pm with the command
6972 o conf lynx "/usr/local/bin/lynx -pscott:tiger"
6974 That's all. Similarly for ncftp or ftp, you would configure something
6977 o conf ncftp "/usr/bin/ncftp -f /home/scott/ncftplogin.cfg"
6979 Your mileage may vary...
6987 I installed a new version of module X but CPAN keeps saying,
6988 I have the old version installed
6990 Most probably you B<do> have the old version installed. This can
6991 happen if a module installs itself into a different directory in the
6992 @INC path than it was previously installed. This is not really a
6993 CPAN.pm problem, you would have the same problem when installing the
6994 module manually. The easiest way to prevent this behaviour is to add
6995 the argument C<UNINST=1> to the C<make install> call, and that is why
6996 many people add this argument permanently by configuring
6998 o conf make_install_arg UNINST=1
7002 So why is UNINST=1 not the default?
7004 Because there are people who have their precise expectations about who
7005 may install where in the @INC path and who uses which @INC array. In
7006 fine tuned environments C<UNINST=1> can cause damage.
7010 I want to clean up my mess, and install a new perl along with
7011 all modules I have. How do I go about it?
7013 Run the autobundle command for your old perl and optionally rename the
7014 resulting bundle file (e.g. Bundle/mybundle.pm), install the new perl
7015 with the Configure option prefix, e.g.
7017 ./Configure -Dprefix=/usr/local/perl-5.6.78.9
7019 Install the bundle file you produced in the first step with something like
7021 cpan> install Bundle::mybundle
7027 When I install bundles or multiple modules with one command
7028 there is too much output to keep track of.
7030 You may want to configure something like
7032 o conf make_arg "| tee -ai /root/.cpan/logs/make.out"
7033 o conf make_install_arg "| tee -ai /root/.cpan/logs/make_install.out"
7035 so that STDOUT is captured in a file for later inspection.
7040 I am not root, how can I install a module in a personal directory?
7042 You will most probably like something like this:
7044 o conf makepl_arg "LIB=~/myperl/lib \
7045 INSTALLMAN1DIR=~/myperl/man/man1 \
7046 INSTALLMAN3DIR=~/myperl/man/man3"
7047 install Sybase::Sybperl
7049 You can make this setting permanent like all C<o conf> settings with
7052 You will have to add ~/myperl/man to the MANPATH environment variable
7053 and also tell your perl programs to look into ~/myperl/lib, e.g. by
7056 use lib "$ENV{HOME}/myperl/lib";
7058 or setting the PERL5LIB environment variable.
7060 Another thing you should bear in mind is that the UNINST parameter
7061 should never be set if you are not root.
7065 How to get a package, unwrap it, and make a change before building it?
7067 look Sybase::Sybperl
7071 I installed a Bundle and had a couple of fails. When I
7072 retried, everything resolved nicely. Can this be fixed to work
7075 The reason for this is that CPAN does not know the dependencies of all
7076 modules when it starts out. To decide about the additional items to
7077 install, it just uses data found in the generated Makefile. An
7078 undetected missing piece breaks the process. But it may well be that
7079 your Bundle installs some prerequisite later than some depending item
7080 and thus your second try is able to resolve everything. Please note,
7081 CPAN.pm does not know the dependency tree in advance and cannot sort
7082 the queue of things to install in a topologically correct order. It
7083 resolves perfectly well IFF all modules declare the prerequisites
7084 correctly with the PREREQ_PM attribute to MakeMaker. For bundles which
7085 fail and you need to install often, it is recommended sort the Bundle
7086 definition file manually. It is planned to improve the metadata
7087 situation for dependencies on CPAN in general, but this will still
7092 In our intranet we have many modules for internal use. How
7093 can I integrate these modules with CPAN.pm but without uploading
7094 the modules to CPAN?
7096 Have a look at the CPAN::Site module.
7100 When I run CPAN's shell, I get error msg about line 1 to 4,
7101 setting meta input/output via the /etc/inputrc file.
7103 Some versions of readline are picky about capitalization in the
7104 /etc/inputrc file and specifically RedHat 6.2 comes with a
7105 /etc/inputrc that contains the word C<on> in lowercase. Change the
7106 occurrences of C<on> to C<On> and the bug should disappear.
7110 Some authors have strange characters in their names.
7112 Internally CPAN.pm uses the UTF-8 charset. If your terminal is
7113 expecting ISO-8859-1 charset, a converter can be activated by setting
7114 term_is_latin to a true value in your config file. One way of doing so
7117 cpan> ! $CPAN::Config->{term_is_latin}=1
7119 Extended support for converters will be made available as soon as perl
7120 becomes stable with regard to charset issues.
7126 We should give coverage for B<all> of the CPAN and not just the PAUSE
7127 part, right? In this discussion CPAN and PAUSE have become equal --
7128 but they are not. PAUSE is authors/, modules/ and scripts/. CPAN is
7129 PAUSE plus the clpa/, doc/, misc/, ports/, and src/.
7131 Future development should be directed towards a better integration of
7134 If a Makefile.PL requires special customization of libraries, prompts
7135 the user for special input, etc. then you may find CPAN is not able to
7136 build the distribution. In that case, you should attempt the
7137 traditional method of building a Perl module package from a shell.
