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

5998 CPAN - query, download and build perl modules from CPAN sites
6004 perl -MCPAN -e shell;
6010 autobundle, clean, install, make, recompile, test
6014 This module will eventually be replaced by CPANPLUS. CPANPLUS is kind
6015 of a modern rewrite from ground up with greater extensibility and more
6016 features but no full compatibility. If you're new to CPAN.pm, you
6017 probably should investigate if CPANPLUS is the better choice for you.
6018 If you're already used to CPAN.pm you're welcome to continue using it,
6019 if you accept that its development is mostly (though not completely)
6024 The CPAN module is designed to automate the make and install of perl
6025 modules and extensions. It includes some primitive searching capabilities and
6026 knows how to use Net::FTP or LWP (or lynx or an external ftp client)
6027 to fetch the raw data from the net.
6029 Modules are fetched from one or more of the mirrored CPAN
6030 (Comprehensive Perl Archive Network) sites and unpacked in a dedicated
6033 The CPAN module also supports the concept of named and versioned
6034 I<bundles> of modules. Bundles simplify the handling of sets of
6035 related modules. See Bundles below.
6037 The package contains a session manager and a cache manager. There is
6038 no status retained between sessions. The session manager keeps track
6039 of what has been fetched, built and installed in the current
6040 session. The cache manager keeps track of the disk space occupied by
6041 the make processes and deletes excess space according to a simple FIFO
6044 For extended searching capabilities there's a plugin for CPAN available,
6045 L<C<CPAN::WAIT>|CPAN::WAIT>. C<CPAN::WAIT> is a full-text search engine
6046 that indexes all documents available in CPAN authors directories. If
6047 C<CPAN::WAIT> is installed on your system, the interactive shell of
6048 CPAN.pm will enable the C<wq>, C<wr>, C<wd>, C<wl>, and C<wh> commands
6049 which send queries to the WAIT server that has been configured for your
6052 All other methods provided are accessible in a programmer style and in an
6053 interactive shell style.
6055 =head2 Interactive Mode
6057 The interactive mode is entered by running
6059 perl -MCPAN -e shell
6061 which puts you into a readline interface. You will have the most fun if
6062 you install Term::ReadKey and Term::ReadLine to enjoy both history and
6065 Once you are on the command line, type 'h' and the rest should be
6068 The function call C<shell> takes two optional arguments, one is the
6069 prompt, the second is the default initial command line (the latter
6070 only works if a real ReadLine interface module is installed).
6072 The most common uses of the interactive modes are
6076 =item Searching for authors, bundles, distribution files and modules
6078 There are corresponding one-letter commands C<a>, C<b>, C<d>, and C<m>
6079 for each of the four categories and another, C<i> for any of the
6080 mentioned four. Each of the four entities is implemented as a class
6081 with slightly differing methods for displaying an object.
6083 Arguments you pass to these commands are either strings exactly matching
6084 the identification string of an object or regular expressions that are
6085 then matched case-insensitively against various attributes of the
6086 objects. The parser recognizes a regular expression only if you
6087 enclose it between two slashes.
6089 The principle is that the number of found objects influences how an
6090 item is displayed. If the search finds one item, the result is
6091 displayed with the rather verbose method C<as_string>, but if we find
6092 more than one, we display each object with the terse method
6095 =item make, test, install, clean modules or distributions
6097 These commands take any number of arguments and investigate what is
6098 necessary to perform the action. If the argument is a distribution
6099 file name (recognized by embedded slashes), it is processed. If it is
6100 a module, CPAN determines the distribution file in which this module
6101 is included and processes that, following any dependencies named in
6102 the module's Makefile.PL (this behavior is controlled by
6103 I<prerequisites_policy>.)
6105 Any C<make> or C<test> are run unconditionally. An
6107 install <distribution_file>
6109 also is run unconditionally. But for
6113 CPAN checks if an install is actually needed for it and prints
6114 I<module up to date> in the case that the distribution file containing
6115 the module doesn't need to be updated.
6117 CPAN also keeps track of what it has done within the current session
6118 and doesn't try to build a package a second time regardless if it
6119 succeeded or not. The C<force> command takes as a first argument the
6120 method to invoke (currently: C<make>, C<test>, or C<install>) and executes the
6121 command from scratch.
6125 cpan> install OpenGL
6126 OpenGL is up to date.
6127 cpan> force install OpenGL
6130 OpenGL-0.4/COPYRIGHT
6133 A C<clean> command results in a
6137 being executed within the distribution file's working directory.
6139 =item get, readme, look module or distribution
6141 C<get> downloads a distribution file without further action. C<readme>
6142 displays the README file of the associated distribution. C<Look> gets
6143 and untars (if not yet done) the distribution file, changes to the
6144 appropriate directory and opens a subshell process in that directory.
6148 C<ls> lists all distribution files in and below an author's CPAN
6149 directory. Only those files that contain modules are listed and if
6150 there is more than one for any given module, only the most recent one
6155 CPAN.pm installs signal handlers for SIGINT and SIGTERM. While you are
6156 in the cpan-shell it is intended that you can press C<^C> anytime and
6157 return to the cpan-shell prompt. A SIGTERM will cause the cpan-shell
6158 to clean up and leave the shell loop. You can emulate the effect of a
6159 SIGTERM by sending two consecutive SIGINTs, which usually means by
6160 pressing C<^C> twice.
6162 CPAN.pm ignores a SIGPIPE. If the user sets inactivity_timeout, a
6163 SIGALRM is used during the run of the C<perl Makefile.PL> subprocess.
6169 The commands that are available in the shell interface are methods in
6170 the package CPAN::Shell. If you enter the shell command, all your
6171 input is split by the Text::ParseWords::shellwords() routine which
6172 acts like most shells do. The first word is being interpreted as the
6173 method to be called and the rest of the words are treated as arguments
6174 to this method. Continuation lines are supported if a line ends with a
6179 C<autobundle> writes a bundle file into the
6180 C<$CPAN::Config-E<gt>{cpan_home}/Bundle> directory. The file contains
6181 a list of all modules that are both available from CPAN and currently
6182 installed within @INC. The name of the bundle file is based on the
6183 current date and a counter.
6187 recompile() is a very special command in that it takes no argument and
6188 runs the make/test/install cycle with brute force over all installed
6189 dynamically loadable extensions (aka XS modules) with 'force' in
6190 effect. The primary purpose of this command is to finish a network
6191 installation. Imagine, you have a common source tree for two different
6192 architectures. You decide to do a completely independent fresh
6193 installation. You start on one architecture with the help of a Bundle
6194 file produced earlier. CPAN installs the whole Bundle for you, but
6195 when you try to repeat the job on the second architecture, CPAN
6196 responds with a C<"Foo up to date"> message for all modules. So you
6197 invoke CPAN's recompile on the second architecture and you're done.
6199 Another popular use for C<recompile> is to act as a rescue in case your
6200 perl breaks binary compatibility. If one of the modules that CPAN uses
6201 is in turn depending on binary compatibility (so you cannot run CPAN
6202 commands), then you should try the CPAN::Nox module for recovery.
6204 =head2 The four C<CPAN::*> Classes: Author, Bundle, Module, Distribution
6206 Although it may be considered internal, the class hierarchy does matter
6207 for both users and programmer. CPAN.pm deals with above mentioned four
6208 classes, and all those classes share a set of methods. A classical
6209 single polymorphism is in effect. A metaclass object registers all
6210 objects of all kinds and indexes them with a string. The strings
6211 referencing objects have a separated namespace (well, not completely
6216 words containing a "/" (slash) Distribution
6217 words starting with Bundle:: Bundle
6218 everything else Module or Author
6220 Modules know their associated Distribution objects. They always refer
6221 to the most recent official release. Developers may mark their releases
6222 as unstable development versions (by inserting an underbar into the
6223 module version number which will also be reflected in the distribution
6224 name when you run 'make dist'), so the really hottest and newest
6225 distribution is not always the default. If a module Foo circulates
6226 on CPAN in both version 1.23 and 1.23_90, CPAN.pm offers a convenient
6227 way to install version 1.23 by saying
6231 This would install the complete distribution file (say
6232 BAR/Foo-1.23.tar.gz) with all accompanying material. But if you would
6233 like to install version 1.23_90, you need to know where the
6234 distribution file resides on CPAN relative to the authors/id/
6235 directory. If the author is BAR, this might be BAR/Foo-1.23_90.tar.gz;
6236 so you would have to say
6238 install BAR/Foo-1.23_90.tar.gz
6240 The first example will be driven by an object of the class
6241 CPAN::Module, the second by an object of class CPAN::Distribution.
6243 =head2 Programmer's interface
6245 If you do not enter the shell, the available shell commands are both
6246 available as methods (C<CPAN::Shell-E<gt>install(...)>) and as
6247 functions in the calling package (C<install(...)>).
6249 There's currently only one class that has a stable interface -
6250 CPAN::Shell. All commands that are available in the CPAN shell are
6251 methods of the class CPAN::Shell. Each of the commands that produce
6252 listings of modules (C<r>, C<autobundle>, C<u>) also return a list of
6253 the IDs of all modules within the list.
6257 =item expand($type,@things)
6259 The IDs of all objects available within a program are strings that can
6260 be expanded to the corresponding real objects with the
6261 C<CPAN::Shell-E<gt>expand("Module",@things)> method. Expand returns a
6262 list of CPAN::Module objects according to the C<@things> arguments
6263 given. In scalar context it only returns the first element of the
6266 =item expandany(@things)
6268 Like expand, but returns objects of the appropriate type, i.e.
6269 CPAN::Bundle objects for bundles, CPAN::Module objects for modules and
6270 CPAN::Distribution objects fro distributions.
6272 =item Programming Examples
6274 This enables the programmer to do operations that combine
6275 functionalities that are available in the shell.
6277 # install everything that is outdated on my disk:
6278 perl -MCPAN -e 'CPAN::Shell->install(CPAN::Shell->r)'
6280 # install my favorite programs if necessary:
6281 for $mod (qw(Net::FTP Digest::MD5 Data::Dumper)){
6282 my $obj = CPAN::Shell->expand('Module',$mod);
6286 # list all modules on my disk that have no VERSION number
6287 for $mod (CPAN::Shell->expand("Module","/./")){
6288 next unless $mod->inst_file;
6289 # MakeMaker convention for undefined $VERSION:
6290 next unless $mod->inst_version eq "undef";
6291 print "No VERSION in ", $mod->id, "\n";
6294 # find out which distribution on CPAN contains a module:
6295 print CPAN::Shell->expand("Module","Apache::Constants")->cpan_file
6297 Or if you want to write a cronjob to watch The CPAN, you could list
6298 all modules that need updating. First a quick and dirty way:
6300 perl -e 'use CPAN; CPAN::Shell->r;'
6302 If you don't want to get any output in the case that all modules are
6303 up to date, you can parse the output of above command for the regular
6304 expression //modules are up to date// and decide to mail the output
6305 only if it doesn't match. Ick?
6307 If you prefer to do it more in a programmer style in one single
6308 process, maybe something like this suits you better:
6310 # list all modules on my disk that have newer versions on CPAN
6311 for $mod (CPAN::Shell->expand("Module","/./")){
6312 next unless $mod->inst_file;
6313 next if $mod->uptodate;
6314 printf "Module %s is installed as %s, could be updated to %s from CPAN\n",
6315 $mod->id, $mod->inst_version, $mod->cpan_version;
6318 If that gives you too much output every day, you maybe only want to
6319 watch for three modules. You can write
6321 for $mod (CPAN::Shell->expand("Module","/Apache|LWP|CGI/")){
6323 as the first line instead. Or you can combine some of the above
6326 # watch only for a new mod_perl module
6327 $mod = CPAN::Shell->expand("Module","mod_perl");
6328 exit if $mod->uptodate;
6329 # new mod_perl arrived, let me know all update recommendations
6334 =head2 Methods in the other Classes
6336 The programming interface for the classes CPAN::Module,
6337 CPAN::Distribution, CPAN::Bundle, and CPAN::Author is still considered
6338 beta and partially even alpha. In the following paragraphs only those
6339 methods are documented that have proven useful over a longer time and
6340 thus are unlikely to change.
6344 =item CPAN::Author::as_glimpse()
6346 Returns a one-line description of the author
6348 =item CPAN::Author::as_string()
6350 Returns a multi-line description of the author
6352 =item CPAN::Author::email()
6354 Returns the author's email address
6356 =item CPAN::Author::fullname()
6358 Returns the author's name

6379 objects may be bundles, modules or distributions.
6381 =item CPAN::Bundle::force($method,@args)
6383 Forces CPAN to perform a task that normally would have failed. Force
6384 takes as arguments a method name to be called and any number of
6385 additional arguments that should be passed to the called method. The
6386 internals of the object get the needed changes so that CPAN.pm does
6387 not refuse to take the action. The C<force> is passed recursively to
6388 all contained objects.
6390 =item CPAN::Bundle::get()
6392 Recursively runs the C<get> method on all items contained in the bundle
6394 =item CPAN::Bundle::inst_file()
6396 Returns the highest installed version of the bundle in either @INC or
6397 C<$CPAN::Config->{cpan_home}>. Note that this is different from
6398 CPAN::Module::inst_file.
6400 =item CPAN::Bundle::inst_version()
6402 Like CPAN::Bundle::inst_file, but returns the $VERSION
6404 =item CPAN::Bundle::uptodate()
6406 Returns 1 if the bundle itself and all its members are uptodate.
6408 =item CPAN::Bundle::install()
6410 Recursively runs the C<install> method on all items contained in the bundle
6412 =item CPAN::Bundle::make()

6428 =item CPAN::Distribution::as_string()
6430 Returns a multi-line description of the distribution
6432 =item CPAN::Distribution::clean()
6434 Changes to the directory where the distribution has been unpacked and
6435 runs C<make clean> there.
6437 =item CPAN::Distribution::containsmods()
6439 Returns a list of IDs of modules contained in a distribution file.
6440 Only works for distributions listed in the 02packages.details.txt.gz
6441 file. This typically means that only the most recent version of a
6442 distribution is covered.
6444 =item CPAN::Distribution::cvs_import()
6446 Changes to the directory where the distribution has been unpacked and
6449 cvs -d $cvs_root import -m $cvs_log $cvs_dir $userid v$version
6453 =item CPAN::Distribution::dir()
6455 Returns the directory into which this distribution has been unpacked.
6457 =item CPAN::Distribution::force($method,@args)
6459 Forces CPAN to perform a task that normally would have failed. Force
6460 takes as arguments a method name to be called and any number of
6461 additional arguments that should be passed to the called method. The
6462 internals of the object get the needed changes so that CPAN.pm does
6463 not refuse to take the action.
6465 =item CPAN::Distribution::get()
6467 Downloads the distribution from CPAN and unpacks it. Does nothing if
6468 the distribution has already been downloaded and unpacked within the
6471 =item CPAN::Distribution::install()
6473 Changes to the directory where the distribution has been unpacked and
6474 runs the external command C<make install> there. If C<make> has not
6475 yet been run, it will be run first. A C<make test> will be issued in
6476 any case and if this fails, the install will be canceled. The
6477 cancellation can be avoided by letting C<force> run the C<install> for
6480 =item CPAN::Distribution::isa_perl()
6482 Returns 1 if this distribution file seems to be a perl distribution.
6483 Normally this is derived from the file name only, but the index from
6484 CPAN can contain a hint to achieve a return value of true for other
6487 =item CPAN::Distribution::look()
6489 Changes to the directory where the distribution has been unpacked and
6490 opens a subshell there. Exiting the subshell returns.
6492 =item CPAN::Distribution::make()
6494 First runs the C<get> method to make sure the distribution is
6495 downloaded and unpacked. Changes to the directory where the
6496 distribution has been unpacked and runs the external commands C<perl
6497 Makefile.PL> and C<make> there.
6499 =item CPAN::Distribution::prereq_pm()
6501 Returns the hash reference that has been announced by a distribution
6502 as the PREREQ_PM hash in the Makefile.PL. Note: works only after an
6503 attempt has been made to C<make> the distribution. Returns undef
6506 =item CPAN::Distribution::readme()
6508 Downloads the README file associated with a distribution and runs it
6509 through the pager specified in C<$CPAN::Config->{pager}>.
6511 =item CPAN::Distribution::test()
6513 Changes to the directory where the distribution has been unpacked and
6514 runs C<make test> there.
6516 =item CPAN::Distribution::uptodate()
6518 Returns 1 if all the modules contained in the distribution are
6519 uptodate. Relies on containsmods.
6521 =item CPAN::Index::force_reload()
6523 Forces a reload of all indices.
6525 =item CPAN::Index::reload()
6527 Reloads all indices if they have been read more than
6528 C<$CPAN::Config->{index_expire}> days.
6530 =item CPAN::InfoObj::dump()
6532 CPAN::Author, CPAN::Bundle, CPAN::Module, and CPAN::Distribution
6533 inherit this method. It prints the data structure associated with an
6534 object. Useful for debugging. Note: the data structure is considered
6535 internal and thus subject to change without notice.
6537 =item CPAN::Module::as_glimpse()
6539 Returns a one-line description of the module
6541 =item CPAN::Module::as_string()
6543 Returns a multi-line description of the module
6545 =item CPAN::Module::clean()
6547 Runs a clean on the distribution associated with this module.
6549 =item CPAN::Module::cpan_file()
6551 Returns the filename on CPAN that is associated with the module.
6553 =item CPAN::Module::cpan_version()
6555 Returns the latest version of this module available on CPAN.
6557 =item CPAN::Module::cvs_import()
6559 Runs a cvs_import on the distribution associated with this module.
6561 =item CPAN::Module::description()
6563 Returns a 44 character description of this module. Only available for
6564 modules listed in The Module List (CPAN/modules/00modlist.long.html
6565 or 00modlist.long.txt.gz)
6567 =item CPAN::Module::force($method,@args)
6569 Forces CPAN to perform a task that normally would have failed. Force
6570 takes as arguments a method name to be called and any number of
6571 additional arguments that should be passed to the called method. The
6572 internals of the object get the needed changes so that CPAN.pm does
6573 not refuse to take the action.
6575 =item CPAN::Module::get()
6577 Runs a get on the distribution associated with this module.
6579 =item CPAN::Module::inst_file()
6581 Returns the filename of the module found in @INC. The first file found
6582 is reported just like perl itself stops searching @INC when it finds a
6585 =item CPAN::Module::inst_version()
6587 Returns the version number of the module in readable format.
6589 =item CPAN::Module::install()
6591 Runs an C<install> on the distribution associated with this module.
6593 =item CPAN::Module::look()
6595 Changes to the directory where the distribution associated with this
6596 module has been unpacked and opens a subshell there. Exiting the
6599 =item CPAN::Module::make()
6601 Runs a C<make> on the distribution associated with this module.
6603 =item CPAN::Module::manpage_headline()
6605 If module is installed, peeks into the module's manpage, reads the
6606 headline and returns it. Moreover, if the module has been downloaded
6607 within this session, does the equivalent on the downloaded module even
6608 if it is not installed.
6610 =item CPAN::Module::readme()
6612 Runs a C<readme> on the distribution associated with this module.
6614 =item CPAN::Module::test()
6616 Runs a C<test> on the distribution associated with this module.
6618 =item CPAN::Module::uptodate()
6620 Returns 1 if the module is installed and up-to-date.
6622 =item CPAN::Module::userid()
6624 Returns the author's ID of the module.
6628 =head2 Cache Manager
6630 Currently the cache manager only keeps track of the build directory
6631 ($CPAN::Config->{build_dir}). It is a simple FIFO mechanism that
6632 deletes complete directories below C<build_dir> as soon as the size of
6633 all directories there gets bigger than $CPAN::Config->{build_cache}
6634 (in MB). The contents of this cache may be used for later
6635 re-installations that you intend to do manually, but will never be
6636 trusted by CPAN itself. This is due to the fact that the user might
6637 use these directories for building modules on different architectures.
6639 There is another directory ($CPAN::Config->{keep_source_where}) where
6640 the original distribution files are kept. This directory is not
6641 covered by the cache manager and must be controlled by the user. If
6642 you choose to have the same directory as build_dir and as
6643 keep_source_where directory, then your sources will be deleted with
6644 the same fifo mechanism.
6648 A bundle is just a perl module in the namespace Bundle:: that does not
6649 define any functions or methods. It usually only contains documentation.
6651 It starts like a perl module with a package declaration and a $VERSION
6652 variable. After that the pod section looks like any other pod with the
6653 only difference being that I<one special pod section> exists starting with
6658 In this pod section each line obeys the format
6660 Module_Name [Version_String] [- optional text]
6662 The only required part is the first field, the name of a module
6663 (e.g. Foo::Bar, ie. I<not> the name of the distribution file). The rest
6664 of the line is optional. The comment part is delimited by a dash just
6665 as in the man page header.
6667 The distribution of a bundle should follow the same convention as
6668 other distributions.
6670 Bundles are treated specially in the CPAN package. If you say 'install
6671 Bundle::Tkkit' (assuming such a bundle exists), CPAN will install all
6672 the modules in the CONTENTS section of the pod. You can install your
6673 own Bundles locally by placing a conformant Bundle file somewhere into
6674 your @INC path. The autobundle() command which is available in the
6675 shell interface does that for you by including all currently installed
6676 modules in a snapshot bundle file.
6678 =head2 Prerequisites
6680 If you have a local mirror of CPAN and can access all files with
6681 "file:" URLs, then you only need a perl better than perl5.003 to run
6682 this module. Otherwise Net::FTP is strongly recommended. LWP may be
6683 required for non-UNIX systems or if your nearest CPAN site is
6684 associated with a URL that is not C<ftp:>.
6686 If you have neither Net::FTP nor LWP, there is a fallback mechanism
6687 implemented for an external ftp command or for an external lynx
6690 =head2 Finding packages and VERSION
6692 This module presumes that all packages on CPAN
6698 declare their $VERSION variable in an easy to parse manner. This
6699 prerequisite can hardly be relaxed because it consumes far too much
6700 memory to load all packages into the running program just to determine
6701 the $VERSION variable. Currently all programs that are dealing with
6702 version use something like this
6704 perl -MExtUtils::MakeMaker -le \
6705 'print MM->parse_version(shift)' filename
6707 If you are author of a package and wonder if your $VERSION can be
6708 parsed, please try the above method.
6712 come as compressed or gzipped tarfiles or as zip files and contain a
6713 Makefile.PL (well, we try to handle a bit more, but without much
6720 The debugging of this module is a bit complex, because we have
6721 interferences of the software producing the indices on CPAN, of the
6722 mirroring process on CPAN, of packaging, of configuration, of
6723 synchronicity, and of bugs within CPAN.pm.
6725 For code debugging in interactive mode you can try "o debug" which
6726 will list options for debugging the various parts of the code. You
6727 should know that "o debug" has built-in completion support.
6729 For data debugging there is the C<dump> command which takes the same
6730 arguments as make/test/install and outputs the object's Data::Dumper
6733 =head2 Floppy, Zip, Offline Mode
6735 CPAN.pm works nicely without network too. If you maintain machines
6736 that are not networked at all, you should consider working with file:
6737 URLs. Of course, you have to collect your modules somewhere first. So
6738 you might use CPAN.pm to put together all you need on a networked
6739 machine. Then copy the $CPAN::Config->{keep_source_where} (but not
6740 $CPAN::Config->{build_dir}) directory on a floppy. This floppy is kind
6741 of a personal CPAN. CPAN.pm on the non-networked machines works nicely
6742 with this floppy. See also below the paragraph about CD-ROM support.
6744 =head1 CONFIGURATION
6746 When the CPAN module is used for the first time, a configuration
6747 dialog tries to determine a couple of site specific options. The
6748 result of the dialog is stored in a hash reference C< $CPAN::Config >
6749 in a file CPAN/Config.pm.
6751 The default values defined in the CPAN/Config.pm file can be
6752 overridden in a user specific file: CPAN/MyConfig.pm. Such a file is
6753 best placed in $HOME/.cpan/CPAN/MyConfig.pm, because $HOME/.cpan is
6754 added to the search path of the CPAN module before the use() or
6755 require() statements.
6757 The configuration dialog can be started any time later again by
6758 issueing the command C< o conf init > in the CPAN shell.
6760 Currently the following keys in the hash reference $CPAN::Config are
6763 build_cache size of cache for directories to build modules
6764 build_dir locally accessible directory to build modules
6765 index_expire after this many days refetch index files
6766 cache_metadata use serializer to cache metadata
6767 cpan_home local directory reserved for this package
6768 dontload_hash anonymous hash: modules in the keys will not be
6769 loaded by the CPAN::has_inst() routine
6770 gzip location of external program gzip
6771 histfile file to maintain history between sessions
6772 histsize maximum number of lines to keep in histfile
6773 inactivity_timeout breaks interactive Makefile.PLs after this
6774 many seconds inactivity. Set to 0 to never break.
6775 inhibit_startup_message
6776 if true, does not print the startup message
6777 keep_source_where directory in which to keep the source (if we do)
6778 make location of external make program
6779 make_arg arguments that should always be passed to 'make'
6780 make_install_arg same as make_arg for 'make install'
6781 makepl_arg arguments passed to 'perl Makefile.PL'
6782 pager location of external program more (or any pager)
6783 prerequisites_policy
6784 what to do if you are missing module prerequisites
6785 ('follow' automatically, 'ask' me, or 'ignore')
6786 proxy_user username for accessing an authenticating proxy
6787 proxy_pass password for accessing an authenticating proxy
6788 scan_cache controls scanning of cache ('atstart' or 'never')
6789 tar location of external program tar
6790 term_is_latin if true internal UTF-8 is translated to ISO-8859-1
6791 (and nonsense for characters outside latin range)
6792 unzip location of external program unzip
6793 urllist arrayref to nearby CPAN sites (or equivalent locations)
6794 wait_list arrayref to a wait server to try (See CPAN::WAIT)
6795 ftp_proxy, } the three usual variables for configuring
6796 http_proxy, } proxy requests. Both as CPAN::Config variables
6797 no_proxy } and as environment variables configurable.
6799 You can set and query each of these options interactively in the cpan
6800 shell with the command set defined within the C<o conf> command:
6804 =item C<o conf E<lt>scalar optionE<gt>>
6806 prints the current value of the I<scalar option>
6808 =item C<o conf E<lt>scalar optionE<gt> E<lt>valueE<gt>>
6810 Sets the value of the I<scalar option> to I<value>
6812 =item C<o conf E<lt>list optionE<gt>>
6814 prints the current value of the I<list option> in MakeMaker's
6817 =item C<o conf E<lt>list optionE<gt> [shift|pop]>
6819 shifts or pops the array in the I<list option> variable
6821 =item C<o conf E<lt>list optionE<gt> [unshift|push|splice] E<lt>listE<gt>>
6823 works like the corresponding perl commands.
6827 =head2 Note on urllist parameter's format
6829 urllist parameters are URLs according to RFC 1738. We do a little
6830 guessing if your URL is not compliant, but if you have problems with
6831 file URLs, please try the correct format. Either:
6833 file://localhost/whatever/ftp/pub/CPAN/
6837 file:///home/ftp/pub/CPAN/
6839 =head2 urllist parameter has CD-ROM support
6841 The C<urllist> parameter of the configuration table contains a list of
6842 URLs that are to be used for downloading. If the list contains any
6843 C<file> URLs, CPAN always tries to get files from there first. This
6844 feature is disabled for index files. So the recommendation for the
6845 owner of a CD-ROM with CPAN contents is: include your local, possibly
6846 outdated CD-ROM as a C<file> URL at the end of urllist, e.g.
6848 o conf urllist push file://localhost/CDROM/CPAN
6850 CPAN.pm will then fetch the index files from one of the CPAN sites
6851 that come at the beginning of urllist. It will later check for each
6852 module if there is a local copy of the most recent version.
6854 Another peculiarity of urllist is that the site that we could
6855 successfully fetch the last file from automatically gets a preference
6856 token and is tried as the first site for the next request. So if you
6857 add a new site at runtime it may happen that the previously preferred
6858 site will be tried another time. This means that if you want to disallow
6859 a site for the next transfer, it must be explicitly removed from
6864 There's no strong security layer in CPAN.pm. CPAN.pm helps you to
6865 install foreign, unmasked, unsigned code on your machine. We compare
6866 to a checksum that comes from the net just as the distribution file
6867 itself. If somebody has managed to tamper with the distribution file,
6868 they may have as well tampered with the CHECKSUMS file. Future
6869 development will go towards strong authentication.
6873 Most functions in package CPAN are exported per default. The reason
6874 for this is that the primary use is intended for the cpan shell or for
6877 =head1 POPULATE AN INSTALLATION WITH LOTS OF MODULES
6879 Populating a freshly installed perl with my favorite modules is pretty
6880 easy if you maintain a private bundle definition file. To get a useful
6881 blueprint of a bundle definition file, the command autobundle can be used
6882 on the CPAN shell command line. This command writes a bundle definition
6883 file for all modules that are installed for the currently running perl
6884 interpreter. It's recommended to run this command only once and from then
6885 on maintain the file manually under a private name, say
6886 Bundle/my_bundle.pm. With a clever bundle file you can then simply say
6888 cpan> install Bundle::my_bundle
6890 then answer a few questions and then go out for a coffee.
6892 Maintaining a bundle definition file means keeping track of two
6893 things: dependencies and interactivity. CPAN.pm sometimes fails on
6894 calculating dependencies because not all modules define all MakeMaker
6895 attributes correctly, so a bundle definition file should specify
6896 prerequisites as early as possible. On the other hand, it's a bit
6897 annoying that many distributions need some interactive configuring. So
6898 what I try to accomplish in my private bundle file is to have the
6899 packages that need to be configured early in the file and the gentle
6900 ones later, so I can go out after a few minutes and leave CPAN.pm
6903 =head1 WORKING WITH CPAN.pm BEHIND FIREWALLS
6905 Thanks to Graham Barr for contributing the following paragraphs about
6906 the interaction between perl, and various firewall configurations. For
6907 further informations on firewalls, it is recommended to consult the
6908 documentation that comes with the ncftp program. If you are unable to
6909 go through the firewall with a simple Perl setup, it is very likely
6910 that you can configure ncftp so that it works for your firewall.
6912 =head2 Three basic types of firewalls
6914 Firewalls can be categorized into three basic types.
6920 This is where the firewall machine runs a web server and to access the
6921 outside world you must do it via the web server. If you set environment
6922 variables like http_proxy or ftp_proxy to a values beginning with http://
6923 or in your web browser you have to set proxy information then you know
6924 you are running an http firewall.
6926 To access servers outside these types of firewalls with perl (even for
6927 ftp) you will need to use LWP.
6931 This where the firewall machine runs an ftp server. This kind of
6932 firewall will only let you access ftp servers outside the firewall.
6933 This is usually done by connecting to the firewall with ftp, then
6934 entering a username like "user@outside.host.com"
6936 To access servers outside these type of firewalls with perl you
6937 will need to use Net::FTP.
6939 =item One way visibility
6941 I say one way visibility as these firewalls try to make themselves look
6942 invisible to the users inside the firewall. An FTP data connection is
6943 normally created by sending the remote server your IP address and then
6944 listening for the connection. But the remote server will not be able to
6945 connect to you because of the firewall. So for these types of firewall
6946 FTP connections need to be done in a passive mode.
6948 There are two that I can think off.
6954 If you are using a SOCKS firewall you will need to compile perl and link
6955 it with the SOCKS library, this is what is normally called a 'socksified'
6956 perl. With this executable you will be able to connect to servers outside
6957 the firewall as if it is not there.
6961 This is the firewall implemented in the Linux kernel, it allows you to
6962 hide a complete network behind one IP address. With this firewall no
6963 special compiling is needed as you can access hosts directly.
6965 For accessing ftp servers behind such firewalls you may need to set
6966 the environment variable C<FTP_PASSIVE> to a true value, e.g.
6968 env FTP_PASSIVE=1 perl -MCPAN -eshell
6972 perl -MCPAN -e '$ENV{FTP_PASSIVE} = 1; shell'
6979 =head2 Configuring lynx or ncftp for going through a firewall
6981 If you can go through your firewall with e.g. lynx, presumably with a
6984 /usr/local/bin/lynx -pscott:tiger
6986 then you would configure CPAN.pm with the command
6988 o conf lynx "/usr/local/bin/lynx -pscott:tiger"
6990 That's all. Similarly for ncftp or ftp, you would configure something
6993 o conf ncftp "/usr/bin/ncftp -f /home/scott/ncftplogin.cfg"
6995 Your mileage may vary...
7003 I installed a new version of module X but CPAN keeps saying,
7004 I have the old version installed
7006 Most probably you B<do> have the old version installed. This can
7007 happen if a module installs itself into a different directory in the
7008 @INC path than it was previously installed. This is not really a
7009 CPAN.pm problem, you would have the same problem when installing the
7010 module manually. The easiest way to prevent this behaviour is to add
7011 the argument C<UNINST=1> to the C<make install> call, and that is why
7012 many people add this argument permanently by configuring
7014 o conf make_install_arg UNINST=1
7018 So why is UNINST=1 not the default?
7020 Because there are people who have their precise expectations about who
7021 may install where in the @INC path and who uses which @INC array. In
7022 fine tuned environments C<UNINST=1> can cause damage.
7026 I want to clean up my mess, and install a new perl along with
7027 all modules I have. How do I go about it?
7029 Run the autobundle command for your old perl and optionally rename the
7030 resulting bundle file (e.g. Bundle/mybundle.pm), install the new perl
7031 with the Configure option prefix, e.g.
7033 ./Configure -Dprefix=/usr/local/perl-5.6.78.9
7035 Install the bundle file you produced in the first step with something like
7037 cpan> install Bundle::mybundle
7043 When I install bundles or multiple modules with one command
7044 there is too much output to keep track of.
7046 You may want to configure something like
7048 o conf make_arg "| tee -ai /root/.cpan/logs/make.out"
7049 o conf make_install_arg "| tee -ai /root/.cpan/logs/make_install.out"
7051 so that STDOUT is captured in a file for later inspection.
7056 I am not root, how can I install a module in a personal directory?
7058 You will most probably like something like this:
7060 o conf makepl_arg "LIB=~/myperl/lib \
7061 INSTALLMAN1DIR=~/myperl/man/man1 \
7062 INSTALLMAN3DIR=~/myperl/man/man3"
7063 install Sybase::Sybperl
7065 You can make this setting permanent like all C<o conf> settings with
7068 You will have to add ~/myperl/man to the MANPATH environment variable
7069 and also tell your perl programs to look into ~/myperl/lib, e.g. by
7072 use lib "$ENV{HOME}/myperl/lib";
7074 or setting the PERL5LIB environment variable.
7076 Another thing you should bear in mind is that the UNINST parameter
7077 should never be set if you are not root.
7081 How to get a package, unwrap it, and make a change before building it?
7083 look Sybase::Sybperl
7087 I installed a Bundle and had a couple of fails. When I
7088 retried, everything resolved nicely. Can this be fixed to work
7091 The reason for this is that CPAN does not know the dependencies of all
7092 modules when it starts out. To decide about the additional items to
7093 install, it just uses data found in the generated Makefile. An
7094 undetected missing piece breaks the process. But it may well be that
7095 your Bundle installs some prerequisite later than some depending item
7096 and thus your second try is able to resolve everything. Please note,
7097 CPAN.pm does not know the dependency tree in advance and cannot sort
7098 the queue of things to install in a topologically correct order. It
7099 resolves perfectly well IFF all modules declare the prerequisites
7100 correctly with the PREREQ_PM attribute to MakeMaker. For bundles which
7101 fail and you need to install often, it is recommended sort the Bundle
7102 definition file manually. It is planned to improve the metadata
7103 situation for dependencies on CPAN in general, but this will still
7108 In our intranet we have many modules for internal use. How
7109 can I integrate these modules with CPAN.pm but without uploading
7110 the modules to CPAN?
7112 Have a look at the CPAN::Site module.
7116 When I run CPAN's shell, I get error msg about line 1 to 4,
7117 setting meta input/output via the /etc/inputrc file.
7119 Some versions of readline are picky about capitalization in the
7120 /etc/inputrc file and specifically RedHat 6.2 comes with a
7121 /etc/inputrc that contains the word C<on> in lowercase. Change the
7122 occurrences of C<on> to C<On> and the bug should disappear.
7126 Some authors have strange characters in their names.
7128 Internally CPAN.pm uses the UTF-8 charset. If your terminal is
7129 expecting ISO-8859-1 charset, a converter can be activated by setting
7130 term_is_latin to a true value in your config file. One way of doing so
7133 cpan> ! $CPAN::Config->{term_is_latin}=1
7135 Extended support for converters will be made available as soon as perl
7136 becomes stable with regard to charset issues.
7142 We should give coverage for B<all> of the CPAN and not just the PAUSE
7143 part, right? In this discussion CPAN and PAUSE have become equal --
7144 but they are not. PAUSE is authors/, modules/ and scripts/. CPAN is
7145 PAUSE plus the clpa/, doc/, misc/, ports/, and src/.
7147 Future development should be directed towards a better integration of
7150 If a Makefile.PL requires special customization of libraries, prompts
7151 the user for special input, etc. then you may find CPAN is not able to
7152 build the distribution. In that case, you should attempt the
7153 traditional method of building a Perl module package from a shell.
