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

6017 CPAN - query, download and build perl modules from CPAN sites
6023 perl -MCPAN -e shell;
6029 autobundle, clean, install, make, recompile, test
6033 This module will eventually be replaced by CPANPLUS. CPANPLUS is kind
6034 of a modern rewrite from ground up with greater extensibility and more
6035 features but no full compatibility. If you're new to CPAN.pm, you
6036 probably should investigate if CPANPLUS is the better choice for you.
6037 If you're already used to CPAN.pm you're welcome to continue using it,
6038 if you accept that its development is mostly (though not completely)
6043 The CPAN module is designed to automate the make and install of perl
6044 modules and extensions. It includes some primitive searching capabilities and
6045 knows how to use Net::FTP or LWP (or lynx or an external ftp client)
6046 to fetch the raw data from the net.
6048 Modules are fetched from one or more of the mirrored CPAN
6049 (Comprehensive Perl Archive Network) sites and unpacked in a dedicated
6052 The CPAN module also supports the concept of named and versioned
6053 I<bundles> of modules. Bundles simplify the handling of sets of
6054 related modules. See Bundles below.
6056 The package contains a session manager and a cache manager. There is
6057 no status retained between sessions. The session manager keeps track
6058 of what has been fetched, built and installed in the current
6059 session. The cache manager keeps track of the disk space occupied by
6060 the make processes and deletes excess space according to a simple FIFO
6063 For extended searching capabilities there's a plugin for CPAN available,
6064 L<C<CPAN::WAIT>|CPAN::WAIT>. C<CPAN::WAIT> is a full-text search engine
6065 that indexes all documents available in CPAN authors directories. If
6066 C<CPAN::WAIT> is installed on your system, the interactive shell of
6067 CPAN.pm will enable the C<wq>, C<wr>, C<wd>, C<wl>, and C<wh> commands
6068 which send queries to the WAIT server that has been configured for your
6071 All other methods provided are accessible in a programmer style and in an
6072 interactive shell style.
6074 =head2 Interactive Mode
6076 The interactive mode is entered by running
6078 perl -MCPAN -e shell
6080 which puts you into a readline interface. You will have the most fun if
6081 you install Term::ReadKey and Term::ReadLine to enjoy both history and
6084 Once you are on the command line, type 'h' and the rest should be
6087 The function call C<shell> takes two optional arguments, one is the
6088 prompt, the second is the default initial command line (the latter
6089 only works if a real ReadLine interface module is installed).
6091 The most common uses of the interactive modes are
6095 =item Searching for authors, bundles, distribution files and modules
6097 There are corresponding one-letter commands C<a>, C<b>, C<d>, and C<m>
6098 for each of the four categories and another, C<i> for any of the
6099 mentioned four. Each of the four entities is implemented as a class
6100 with slightly differing methods for displaying an object.
6102 Arguments you pass to these commands are either strings exactly matching
6103 the identification string of an object or regular expressions that are
6104 then matched case-insensitively against various attributes of the
6105 objects. The parser recognizes a regular expression only if you
6106 enclose it between two slashes.
6108 The principle is that the number of found objects influences how an
6109 item is displayed. If the search finds one item, the result is
6110 displayed with the rather verbose method C<as_string>, but if we find
6111 more than one, we display each object with the terse method
6114 =item make, test, install, clean modules or distributions
6116 These commands take any number of arguments and investigate what is
6117 necessary to perform the action. If the argument is a distribution
6118 file name (recognized by embedded slashes), it is processed. If it is
6119 a module, CPAN determines the distribution file in which this module
6120 is included and processes that, following any dependencies named in
6121 the module's Makefile.PL (this behavior is controlled by
6122 I<prerequisites_policy>.)
6124 Any C<make> or C<test> are run unconditionally. An
6126 install <distribution_file>
6128 also is run unconditionally. But for
6132 CPAN checks if an install is actually needed for it and prints
6133 I<module up to date> in the case that the distribution file containing
6134 the module doesn't need to be updated.
6136 CPAN also keeps track of what it has done within the current session
6137 and doesn't try to build a package a second time regardless if it
6138 succeeded or not. The C<force> command takes as a first argument the
6139 method to invoke (currently: C<make>, C<test>, or C<install>) and executes the
6140 command from scratch.
6144 cpan> install OpenGL
6145 OpenGL is up to date.
6146 cpan> force install OpenGL
6149 OpenGL-0.4/COPYRIGHT
6152 A C<clean> command results in a
6156 being executed within the distribution file's working directory.
6158 =item get, readme, look module or distribution
6160 C<get> downloads a distribution file without further action. C<readme>
6161 displays the README file of the associated distribution. C<Look> gets
6162 and untars (if not yet done) the distribution file, changes to the
6163 appropriate directory and opens a subshell process in that directory.
6167 C<ls> lists all distribution files in and below an author's CPAN
6168 directory. Only those files that contain modules are listed and if
6169 there is more than one for any given module, only the most recent one
6174 CPAN.pm installs signal handlers for SIGINT and SIGTERM. While you are
6175 in the cpan-shell it is intended that you can press C<^C> anytime and
6176 return to the cpan-shell prompt. A SIGTERM will cause the cpan-shell
6177 to clean up and leave the shell loop. You can emulate the effect of a
6178 SIGTERM by sending two consecutive SIGINTs, which usually means by
6179 pressing C<^C> twice.
6181 CPAN.pm ignores a SIGPIPE. If the user sets inactivity_timeout, a
6182 SIGALRM is used during the run of the C<perl Makefile.PL> subprocess.
6188 The commands that are available in the shell interface are methods in
6189 the package CPAN::Shell. If you enter the shell command, all your
6190 input is split by the Text::ParseWords::shellwords() routine which
6191 acts like most shells do. The first word is being interpreted as the
6192 method to be called and the rest of the words are treated as arguments
6193 to this method. Continuation lines are supported if a line ends with a
6198 C<autobundle> writes a bundle file into the
6199 C<$CPAN::Config-E<gt>{cpan_home}/Bundle> directory. The file contains
6200 a list of all modules that are both available from CPAN and currently
6201 installed within @INC. The name of the bundle file is based on the
6202 current date and a counter.
6206 recompile() is a very special command in that it takes no argument and
6207 runs the make/test/install cycle with brute force over all installed
6208 dynamically loadable extensions (aka XS modules) with 'force' in
6209 effect. The primary purpose of this command is to finish a network
6210 installation. Imagine, you have a common source tree for two different
6211 architectures. You decide to do a completely independent fresh
6212 installation. You start on one architecture with the help of a Bundle
6213 file produced earlier. CPAN installs the whole Bundle for you, but
6214 when you try to repeat the job on the second architecture, CPAN
6215 responds with a C<"Foo up to date"> message for all modules. So you
6216 invoke CPAN's recompile on the second architecture and you're done.
6218 Another popular use for C<recompile> is to act as a rescue in case your
6219 perl breaks binary compatibility. If one of the modules that CPAN uses
6220 is in turn depending on binary compatibility (so you cannot run CPAN
6221 commands), then you should try the CPAN::Nox module for recovery.
6223 =head2 The four C<CPAN::*> Classes: Author, Bundle, Module, Distribution
6225 Although it may be considered internal, the class hierarchy does matter
6226 for both users and programmer. CPAN.pm deals with above mentioned four
6227 classes, and all those classes share a set of methods. A classical
6228 single polymorphism is in effect. A metaclass object registers all
6229 objects of all kinds and indexes them with a string. The strings
6230 referencing objects have a separated namespace (well, not completely
6235 words containing a "/" (slash) Distribution
6236 words starting with Bundle:: Bundle
6237 everything else Module or Author
6239 Modules know their associated Distribution objects. They always refer
6240 to the most recent official release. Developers may mark their releases
6241 as unstable development versions (by inserting an underbar into the
6242 module version number which will also be reflected in the distribution
6243 name when you run 'make dist'), so the really hottest and newest
6244 distribution is not always the default. If a module Foo circulates
6245 on CPAN in both version 1.23 and 1.23_90, CPAN.pm offers a convenient
6246 way to install version 1.23 by saying
6250 This would install the complete distribution file (say
6251 BAR/Foo-1.23.tar.gz) with all accompanying material. But if you would
6252 like to install version 1.23_90, you need to know where the
6253 distribution file resides on CPAN relative to the authors/id/
6254 directory. If the author is BAR, this might be BAR/Foo-1.23_90.tar.gz;
6255 so you would have to say
6257 install BAR/Foo-1.23_90.tar.gz
6259 The first example will be driven by an object of the class
6260 CPAN::Module, the second by an object of class CPAN::Distribution.
6262 =head2 Programmer's interface
6264 If you do not enter the shell, the available shell commands are both
6265 available as methods (C<CPAN::Shell-E<gt>install(...)>) and as
6266 functions in the calling package (C<install(...)>).
6268 There's currently only one class that has a stable interface -
6269 CPAN::Shell. All commands that are available in the CPAN shell are
6270 methods of the class CPAN::Shell. Each of the commands that produce
6271 listings of modules (C<r>, C<autobundle>, C<u>) also return a list of
6272 the IDs of all modules within the list.
6276 =item expand($type,@things)
6278 The IDs of all objects available within a program are strings that can
6279 be expanded to the corresponding real objects with the
6280 C<CPAN::Shell-E<gt>expand("Module",@things)> method. Expand returns a
6281 list of CPAN::Module objects according to the C<@things> arguments
6282 given. In scalar context it only returns the first element of the
6285 =item expandany(@things)
6287 Like expand, but returns objects of the appropriate type, i.e.
6288 CPAN::Bundle objects for bundles, CPAN::Module objects for modules and
6289 CPAN::Distribution objects fro distributions.
6291 =item Programming Examples
6293 This enables the programmer to do operations that combine
6294 functionalities that are available in the shell.
6296 # install everything that is outdated on my disk:
6297 perl -MCPAN -e 'CPAN::Shell->install(CPAN::Shell->r)'
6299 # install my favorite programs if necessary:
6300 for $mod (qw(Net::FTP Digest::MD5 Data::Dumper)){
6301 my $obj = CPAN::Shell->expand('Module',$mod);
6305 # list all modules on my disk that have no VERSION number
6306 for $mod (CPAN::Shell->expand("Module","/./")){
6307 next unless $mod->inst_file;
6308 # MakeMaker convention for undefined $VERSION:
6309 next unless $mod->inst_version eq "undef";
6310 print "No VERSION in ", $mod->id, "\n";
6313 # find out which distribution on CPAN contains a module:
6314 print CPAN::Shell->expand("Module","Apache::Constants")->cpan_file
6316 Or if you want to write a cronjob to watch The CPAN, you could list
6317 all modules that need updating. First a quick and dirty way:
6319 perl -e 'use CPAN; CPAN::Shell->r;'
6321 If you don't want to get any output in the case that all modules are
6322 up to date, you can parse the output of above command for the regular
6323 expression //modules are up to date// and decide to mail the output
6324 only if it doesn't match. Ick?
6326 If you prefer to do it more in a programmer style in one single
6327 process, maybe something like this suits you better:
6329 # list all modules on my disk that have newer versions on CPAN
6330 for $mod (CPAN::Shell->expand("Module","/./")){
6331 next unless $mod->inst_file;
6332 next if $mod->uptodate;
6333 printf "Module %s is installed as %s, could be updated to %s from CPAN\n",
6334 $mod->id, $mod->inst_version, $mod->cpan_version;
6337 If that gives you too much output every day, you maybe only want to
6338 watch for three modules. You can write
6340 for $mod (CPAN::Shell->expand("Module","/Apache|LWP|CGI/")){
6342 as the first line instead. Or you can combine some of the above
6345 # watch only for a new mod_perl module
6346 $mod = CPAN::Shell->expand("Module","mod_perl");
6347 exit if $mod->uptodate;
6348 # new mod_perl arrived, let me know all update recommendations
6353 =head2 Methods in the other Classes
6355 The programming interface for the classes CPAN::Module,
6356 CPAN::Distribution, CPAN::Bundle, and CPAN::Author is still considered
6357 beta and partially even alpha. In the following paragraphs only those
6358 methods are documented that have proven useful over a longer time and
6359 thus are unlikely to change.
6363 =item CPAN::Author::as_glimpse()
6365 Returns a one-line description of the author
6367 =item CPAN::Author::as_string()
6369 Returns a multi-line description of the author
6371 =item CPAN::Author::email()
6373 Returns the author's email address
6375 =item CPAN::Author::fullname()

6398 objects may be bundles, modules or distributions.
6400 =item CPAN::Bundle::force($method,@args)
6402 Forces CPAN to perform a task that normally would have failed. Force
6403 takes as arguments a method name to be called and any number of
6404 additional arguments that should be passed to the called method. The
6405 internals of the object get the needed changes so that CPAN.pm does
6406 not refuse to take the action. The C<force> is passed recursively to
6407 all contained objects.
6409 =item CPAN::Bundle::get()
6411 Recursively runs the C<get> method on all items contained in the bundle
6413 =item CPAN::Bundle::inst_file()
6415 Returns the highest installed version of the bundle in either @INC or
6416 C<$CPAN::Config->{cpan_home}>. Note that this is different from
6417 CPAN::Module::inst_file.
6419 =item CPAN::Bundle::inst_version()
6421 Like CPAN::Bundle::inst_file, but returns the $VERSION
6423 =item CPAN::Bundle::uptodate()
6425 Returns 1 if the bundle itself and all its members are uptodate.
6427 =item CPAN::Bundle::install()
6429 Recursively runs the C<install> method on all items contained in the bundle
6431 =item CPAN::Bundle::make()

6447 =item CPAN::Distribution::as_string()
6449 Returns a multi-line description of the distribution
6451 =item CPAN::Distribution::clean()
6453 Changes to the directory where the distribution has been unpacked and
6454 runs C<make clean> there.
6456 =item CPAN::Distribution::containsmods()
6458 Returns a list of IDs of modules contained in a distribution file.
6459 Only works for distributions listed in the 02packages.details.txt.gz
6460 file. This typically means that only the most recent version of a
6461 distribution is covered.
6463 =item CPAN::Distribution::cvs_import()
6465 Changes to the directory where the distribution has been unpacked and
6468 cvs -d $cvs_root import -m $cvs_log $cvs_dir $userid v$version
6472 =item CPAN::Distribution::dir()
6474 Returns the directory into which this distribution has been unpacked.
6476 =item CPAN::Distribution::force($method,@args)
6478 Forces CPAN to perform a task that normally would have failed. Force
6479 takes as arguments a method name to be called and any number of
6480 additional arguments that should be passed to the called method. The
6481 internals of the object get the needed changes so that CPAN.pm does
6482 not refuse to take the action.
6484 =item CPAN::Distribution::get()
6486 Downloads the distribution from CPAN and unpacks it. Does nothing if
6487 the distribution has already been downloaded and unpacked within the
6490 =item CPAN::Distribution::install()
6492 Changes to the directory where the distribution has been unpacked and
6493 runs the external command C<make install> there. If C<make> has not
6494 yet been run, it will be run first. A C<make test> will be issued in
6495 any case and if this fails, the install will be canceled. The
6496 cancellation can be avoided by letting C<force> run the C<install> for
6499 =item CPAN::Distribution::isa_perl()
6501 Returns 1 if this distribution file seems to be a perl distribution.
6502 Normally this is derived from the file name only, but the index from
6503 CPAN can contain a hint to achieve a return value of true for other
6506 =item CPAN::Distribution::look()
6508 Changes to the directory where the distribution has been unpacked and
6509 opens a subshell there. Exiting the subshell returns.
6511 =item CPAN::Distribution::make()
6513 First runs the C<get> method to make sure the distribution is
6514 downloaded and unpacked. Changes to the directory where the
6515 distribution has been unpacked and runs the external commands C<perl
6516 Makefile.PL> and C<make> there.
6518 =item CPAN::Distribution::prereq_pm()
6520 Returns the hash reference that has been announced by a distribution
6521 as the PREREQ_PM hash in the Makefile.PL. Note: works only after an
6522 attempt has been made to C<make> the distribution. Returns undef
6525 =item CPAN::Distribution::readme()
6527 Downloads the README file associated with a distribution and runs it
6528 through the pager specified in C<$CPAN::Config->{pager}>.
6530 =item CPAN::Distribution::test()
6532 Changes to the directory where the distribution has been unpacked and
6533 runs C<make test> there.
6535 =item CPAN::Distribution::uptodate()
6537 Returns 1 if all the modules contained in the distribution are
6538 uptodate. Relies on containsmods.
6540 =item CPAN::Index::force_reload()
6542 Forces a reload of all indices.
6544 =item CPAN::Index::reload()
6546 Reloads all indices if they have been read more than
6547 C<$CPAN::Config->{index_expire}> days.
6549 =item CPAN::InfoObj::dump()
6551 CPAN::Author, CPAN::Bundle, CPAN::Module, and CPAN::Distribution
6552 inherit this method. It prints the data structure associated with an
6553 object. Useful for debugging. Note: the data structure is considered
6554 internal and thus subject to change without notice.
6556 =item CPAN::Module::as_glimpse()
6558 Returns a one-line description of the module
6560 =item CPAN::Module::as_string()
6562 Returns a multi-line description of the module
6564 =item CPAN::Module::clean()
6566 Runs a clean on the distribution associated with this module.
6568 =item CPAN::Module::cpan_file()
6570 Returns the filename on CPAN that is associated with the module.
6572 =item CPAN::Module::cpan_version()
6574 Returns the latest version of this module available on CPAN.
6576 =item CPAN::Module::cvs_import()
6578 Runs a cvs_import on the distribution associated with this module.
6580 =item CPAN::Module::description()
6582 Returns a 44 character description of this module. Only available for
6583 modules listed in The Module List (CPAN/modules/00modlist.long.html
6584 or 00modlist.long.txt.gz)
6586 =item CPAN::Module::force($method,@args)
6588 Forces CPAN to perform a task that normally would have failed. Force
6589 takes as arguments a method name to be called and any number of
6590 additional arguments that should be passed to the called method. The
6591 internals of the object get the needed changes so that CPAN.pm does
6592 not refuse to take the action.
6594 =item CPAN::Module::get()
6596 Runs a get on the distribution associated with this module.
6598 =item CPAN::Module::inst_file()
6600 Returns the filename of the module found in @INC. The first file found
6601 is reported just like perl itself stops searching @INC when it finds a
6604 =item CPAN::Module::inst_version()
6606 Returns the version number of the module in readable format.
6608 =item CPAN::Module::install()
6610 Runs an C<install> on the distribution associated with this module.
6612 =item CPAN::Module::look()
6614 Changes to the directory where the distribution associated with this
6615 module has been unpacked and opens a subshell there. Exiting the
6618 =item CPAN::Module::make()
6620 Runs a C<make> on the distribution associated with this module.
6622 =item CPAN::Module::manpage_headline()
6624 If module is installed, peeks into the module's manpage, reads the
6625 headline and returns it. Moreover, if the module has been downloaded
6626 within this session, does the equivalent on the downloaded module even
6627 if it is not installed.
6629 =item CPAN::Module::readme()
6631 Runs a C<readme> on the distribution associated with this module.
6633 =item CPAN::Module::test()
6635 Runs a C<test> on the distribution associated with this module.
6637 =item CPAN::Module::uptodate()
6639 Returns 1 if the module is installed and up-to-date.
6641 =item CPAN::Module::userid()
6643 Returns the author's ID of the module.
6647 =head2 Cache Manager
6649 Currently the cache manager only keeps track of the build directory
6650 ($CPAN::Config->{build_dir}). It is a simple FIFO mechanism that
6651 deletes complete directories below C<build_dir> as soon as the size of
6652 all directories there gets bigger than $CPAN::Config->{build_cache}
6653 (in MB). The contents of this cache may be used for later
6654 re-installations that you intend to do manually, but will never be
6655 trusted by CPAN itself. This is due to the fact that the user might
6656 use these directories for building modules on different architectures.
6658 There is another directory ($CPAN::Config->{keep_source_where}) where
6659 the original distribution files are kept. This directory is not
6660 covered by the cache manager and must be controlled by the user. If
6661 you choose to have the same directory as build_dir and as
6662 keep_source_where directory, then your sources will be deleted with
6663 the same fifo mechanism.
6667 A bundle is just a perl module in the namespace Bundle:: that does not
6668 define any functions or methods. It usually only contains documentation.
6670 It starts like a perl module with a package declaration and a $VERSION
6671 variable. After that the pod section looks like any other pod with the
6672 only difference being that I<one special pod section> exists starting with
6677 In this pod section each line obeys the format
6679 Module_Name [Version_String] [- optional text]
6681 The only required part is the first field, the name of a module
6682 (e.g. Foo::Bar, ie. I<not> the name of the distribution file). The rest
6683 of the line is optional. The comment part is delimited by a dash just
6684 as in the man page header.
6686 The distribution of a bundle should follow the same convention as
6687 other distributions.
6689 Bundles are treated specially in the CPAN package. If you say 'install
6690 Bundle::Tkkit' (assuming such a bundle exists), CPAN will install all
6691 the modules in the CONTENTS section of the pod. You can install your
6692 own Bundles locally by placing a conformant Bundle file somewhere into
6693 your @INC path. The autobundle() command which is available in the
6694 shell interface does that for you by including all currently installed
6695 modules in a snapshot bundle file.
6697 =head2 Prerequisites
6699 If you have a local mirror of CPAN and can access all files with
6700 "file:" URLs, then you only need a perl better than perl5.003 to run
6701 this module. Otherwise Net::FTP is strongly recommended. LWP may be
6702 required for non-UNIX systems or if your nearest CPAN site is
6703 associated with a URL that is not C<ftp:>.
6705 If you have neither Net::FTP nor LWP, there is a fallback mechanism
6706 implemented for an external ftp command or for an external lynx
6709 =head2 Finding packages and VERSION
6711 This module presumes that all packages on CPAN
6717 declare their $VERSION variable in an easy to parse manner. This
6718 prerequisite can hardly be relaxed because it consumes far too much
6719 memory to load all packages into the running program just to determine
6720 the $VERSION variable. Currently all programs that are dealing with
6721 version use something like this
6723 perl -MExtUtils::MakeMaker -le \
6724 'print MM->parse_version(shift)' filename
6726 If you are author of a package and wonder if your $VERSION can be
6727 parsed, please try the above method.
6731 come as compressed or gzipped tarfiles or as zip files and contain a
6732 Makefile.PL (well, we try to handle a bit more, but without much
6739 The debugging of this module is a bit complex, because we have
6740 interferences of the software producing the indices on CPAN, of the
6741 mirroring process on CPAN, of packaging, of configuration, of
6742 synchronicity, and of bugs within CPAN.pm.
6744 For code debugging in interactive mode you can try "o debug" which
6745 will list options for debugging the various parts of the code. You
6746 should know that "o debug" has built-in completion support.
6748 For data debugging there is the C<dump> command which takes the same
6749 arguments as make/test/install and outputs the object's Data::Dumper
6752 =head2 Floppy, Zip, Offline Mode
6754 CPAN.pm works nicely without network too. If you maintain machines
6755 that are not networked at all, you should consider working with file:
6756 URLs. Of course, you have to collect your modules somewhere first. So
6757 you might use CPAN.pm to put together all you need on a networked
6758 machine. Then copy the $CPAN::Config->{keep_source_where} (but not
6759 $CPAN::Config->{build_dir}) directory on a floppy. This floppy is kind
6760 of a personal CPAN. CPAN.pm on the non-networked machines works nicely
6761 with this floppy. See also below the paragraph about CD-ROM support.
6763 =head1 CONFIGURATION
6765 When the CPAN module is used for the first time, a configuration
6766 dialog tries to determine a couple of site specific options. The
6767 result of the dialog is stored in a hash reference C< $CPAN::Config >
6768 in a file CPAN/Config.pm.
6770 The default values defined in the CPAN/Config.pm file can be
6771 overridden in a user specific file: CPAN/MyConfig.pm. Such a file is
6772 best placed in $HOME/.cpan/CPAN/MyConfig.pm, because $HOME/.cpan is
6773 added to the search path of the CPAN module before the use() or
6774 require() statements.
6776 The configuration dialog can be started any time later again by
6777 issuing the command C< o conf init > in the CPAN shell.
6779 Currently the following keys in the hash reference $CPAN::Config are
6782 build_cache size of cache for directories to build modules
6783 build_dir locally accessible directory to build modules
6784 index_expire after this many days refetch index files
6785 cache_metadata use serializer to cache metadata
6786 cpan_home local directory reserved for this package
6787 dontload_hash anonymous hash: modules in the keys will not be
6788 loaded by the CPAN::has_inst() routine
6789 gzip location of external program gzip
6790 histfile file to maintain history between sessions
6791 histsize maximum number of lines to keep in histfile
6792 inactivity_timeout breaks interactive Makefile.PLs after this
6793 many seconds inactivity. Set to 0 to never break.
6794 inhibit_startup_message
6795 if true, does not print the startup message
6796 keep_source_where directory in which to keep the source (if we do)
6797 make location of external make program
6798 make_arg arguments that should always be passed to 'make'
6799 make_install_arg same as make_arg for 'make install'
6800 makepl_arg arguments passed to 'perl Makefile.PL'
6801 pager location of external program more (or any pager)
6802 prerequisites_policy
6803 what to do if you are missing module prerequisites
6804 ('follow' automatically, 'ask' me, or 'ignore')
6805 proxy_user username for accessing an authenticating proxy
6806 proxy_pass password for accessing an authenticating proxy
6807 scan_cache controls scanning of cache ('atstart' or 'never')
6808 tar location of external program tar
6809 term_is_latin if true internal UTF-8 is translated to ISO-8859-1
6810 (and nonsense for characters outside latin range)
6811 unzip location of external program unzip
6812 urllist arrayref to nearby CPAN sites (or equivalent locations)
6813 wait_list arrayref to a wait server to try (See CPAN::WAIT)
6814 ftp_proxy, } the three usual variables for configuring
6815 http_proxy, } proxy requests. Both as CPAN::Config variables
6816 no_proxy } and as environment variables configurable.
6818 You can set and query each of these options interactively in the cpan
6819 shell with the command set defined within the C<o conf> command:
6823 =item C<o conf E<lt>scalar optionE<gt>>
6825 prints the current value of the I<scalar option>
6827 =item C<o conf E<lt>scalar optionE<gt> E<lt>valueE<gt>>
6829 Sets the value of the I<scalar option> to I<value>
6831 =item C<o conf E<lt>list optionE<gt>>
6833 prints the current value of the I<list option> in MakeMaker's
6836 =item C<o conf E<lt>list optionE<gt> [shift|pop]>
6838 shifts or pops the array in the I<list option> variable
6840 =item C<o conf E<lt>list optionE<gt> [unshift|push|splice] E<lt>listE<gt>>
6842 works like the corresponding perl commands.
6846 =head2 Note on urllist parameter's format
6848 urllist parameters are URLs according to RFC 1738. We do a little
6849 guessing if your URL is not compliant, but if you have problems with
6850 file URLs, please try the correct format. Either:
6852 file://localhost/whatever/ftp/pub/CPAN/
6856 file:///home/ftp/pub/CPAN/
6858 =head2 urllist parameter has CD-ROM support
6860 The C<urllist> parameter of the configuration table contains a list of
6861 URLs that are to be used for downloading. If the list contains any
6862 C<file> URLs, CPAN always tries to get files from there first. This
6863 feature is disabled for index files. So the recommendation for the
6864 owner of a CD-ROM with CPAN contents is: include your local, possibly
6865 outdated CD-ROM as a C<file> URL at the end of urllist, e.g.
6867 o conf urllist push file://localhost/CDROM/CPAN
6869 CPAN.pm will then fetch the index files from one of the CPAN sites
6870 that come at the beginning of urllist. It will later check for each
6871 module if there is a local copy of the most recent version.
6873 Another peculiarity of urllist is that the site that we could
6874 successfully fetch the last file from automatically gets a preference
6875 token and is tried as the first site for the next request. So if you
6876 add a new site at runtime it may happen that the previously preferred
6877 site will be tried another time. This means that if you want to disallow
6878 a site for the next transfer, it must be explicitly removed from
6883 There's no strong security layer in CPAN.pm. CPAN.pm helps you to
6884 install foreign, unmasked, unsigned code on your machine. We compare
6885 to a checksum that comes from the net just as the distribution file
6886 itself. If somebody has managed to tamper with the distribution file,
6887 they may have as well tampered with the CHECKSUMS file. Future
6888 development will go towards strong authentication.
6892 Most functions in package CPAN are exported per default. The reason
6893 for this is that the primary use is intended for the cpan shell or for
6896 =head1 POPULATE AN INSTALLATION WITH LOTS OF MODULES
6898 Populating a freshly installed perl with my favorite modules is pretty
6899 easy if you maintain a private bundle definition file. To get a useful
6900 blueprint of a bundle definition file, the command autobundle can be used
6901 on the CPAN shell command line. This command writes a bundle definition
6902 file for all modules that are installed for the currently running perl
6903 interpreter. It's recommended to run this command only once and from then
6904 on maintain the file manually under a private name, say
6905 Bundle/my_bundle.pm. With a clever bundle file you can then simply say
6907 cpan> install Bundle::my_bundle
6909 then answer a few questions and then go out for a coffee.
6911 Maintaining a bundle definition file means keeping track of two
6912 things: dependencies and interactivity. CPAN.pm sometimes fails on
6913 calculating dependencies because not all modules define all MakeMaker
6914 attributes correctly, so a bundle definition file should specify
6915 prerequisites as early as possible. On the other hand, it's a bit
6916 annoying that many distributions need some interactive configuring. So
6917 what I try to accomplish in my private bundle file is to have the
6918 packages that need to be configured early in the file and the gentle
6919 ones later, so I can go out after a few minutes and leave CPAN.pm
6922 =head1 WORKING WITH CPAN.pm BEHIND FIREWALLS
6924 Thanks to Graham Barr for contributing the following paragraphs about
6925 the interaction between perl, and various firewall configurations. For
6926 further information on firewalls, it is recommended to consult the
6927 documentation that comes with the ncftp program. If you are unable to
6928 go through the firewall with a simple Perl setup, it is very likely
6929 that you can configure ncftp so that it works for your firewall.
6931 =head2 Three basic types of firewalls
6933 Firewalls can be categorized into three basic types.
6939 This is where the firewall machine runs a web server and to access the
6940 outside world you must do it via the web server. If you set environment
6941 variables like http_proxy or ftp_proxy to a values beginning with http://
6942 or in your web browser you have to set proxy information then you know
6943 you are running an http firewall.
6945 To access servers outside these types of firewalls with perl (even for
6946 ftp) you will need to use LWP.
6950 This where the firewall machine runs an ftp server. This kind of
6951 firewall will only let you access ftp servers outside the firewall.
6952 This is usually done by connecting to the firewall with ftp, then
6953 entering a username like "user@outside.host.com"
6955 To access servers outside these type of firewalls with perl you
6956 will need to use Net::FTP.
6958 =item One way visibility
6960 I say one way visibility as these firewalls try to make themselves look
6961 invisible to the users inside the firewall. An FTP data connection is
6962 normally created by sending the remote server your IP address and then
6963 listening for the connection. But the remote server will not be able to
6964 connect to you because of the firewall. So for these types of firewall
6965 FTP connections need to be done in a passive mode.
6967 There are two that I can think off.
6973 If you are using a SOCKS firewall you will need to compile perl and link
6974 it with the SOCKS library, this is what is normally called a 'socksified'
6975 perl. With this executable you will be able to connect to servers outside
6976 the firewall as if it is not there.
6980 This is the firewall implemented in the Linux kernel, it allows you to
6981 hide a complete network behind one IP address. With this firewall no
6982 special compiling is needed as you can access hosts directly.
6984 For accessing ftp servers behind such firewalls you may need to set
6985 the environment variable C<FTP_PASSIVE> to a true value, e.g.
6987 env FTP_PASSIVE=1 perl -MCPAN -eshell
6991 perl -MCPAN -e '$ENV{FTP_PASSIVE} = 1; shell'
6998 =head2 Configuring lynx or ncftp for going through a firewall
7000 If you can go through your firewall with e.g. lynx, presumably with a
7003 /usr/local/bin/lynx -pscott:tiger
7005 then you would configure CPAN.pm with the command
7007 o conf lynx "/usr/local/bin/lynx -pscott:tiger"
7009 That's all. Similarly for ncftp or ftp, you would configure something
7012 o conf ncftp "/usr/bin/ncftp -f /home/scott/ncftplogin.cfg"
7014 Your mileage may vary...
7022 I installed a new version of module X but CPAN keeps saying,
7023 I have the old version installed
7025 Most probably you B<do> have the old version installed. This can
7026 happen if a module installs itself into a different directory in the
7027 @INC path than it was previously installed. This is not really a
7028 CPAN.pm problem, you would have the same problem when installing the
7029 module manually. The easiest way to prevent this behaviour is to add
7030 the argument C<UNINST=1> to the C<make install> call, and that is why
7031 many people add this argument permanently by configuring
7033 o conf make_install_arg UNINST=1
7037 So why is UNINST=1 not the default?
7039 Because there are people who have their precise expectations about who
7040 may install where in the @INC path and who uses which @INC array. In
7041 fine tuned environments C<UNINST=1> can cause damage.
7045 I want to clean up my mess, and install a new perl along with
7046 all modules I have. How do I go about it?
7048 Run the autobundle command for your old perl and optionally rename the
7049 resulting bundle file (e.g. Bundle/mybundle.pm), install the new perl
7050 with the Configure option prefix, e.g.
7052 ./Configure -Dprefix=/usr/local/perl-5.6.78.9
7054 Install the bundle file you produced in the first step with something like
7056 cpan> install Bundle::mybundle
7062 When I install bundles or multiple modules with one command
7063 there is too much output to keep track of.
7065 You may want to configure something like
7067 o conf make_arg "| tee -ai /root/.cpan/logs/make.out"
7068 o conf make_install_arg "| tee -ai /root/.cpan/logs/make_install.out"
7070 so that STDOUT is captured in a file for later inspection.
7075 I am not root, how can I install a module in a personal directory?
7077 You will most probably like something like this:
7079 o conf makepl_arg "LIB=~/myperl/lib \
7080 INSTALLMAN1DIR=~/myperl/man/man1 \
7081 INSTALLMAN3DIR=~/myperl/man/man3"
7082 install Sybase::Sybperl
7084 You can make this setting permanent like all C<o conf> settings with
7087 You will have to add ~/myperl/man to the MANPATH environment variable
7088 and also tell your perl programs to look into ~/myperl/lib, e.g. by
7091 use lib "$ENV{HOME}/myperl/lib";
7093 or setting the PERL5LIB environment variable.
7095 Another thing you should bear in mind is that the UNINST parameter
7096 should never be set if you are not root.
7100 How to get a package, unwrap it, and make a change before building it?
7102 look Sybase::Sybperl
7106 I installed a Bundle and had a couple of fails. When I
7107 retried, everything resolved nicely. Can this be fixed to work
7110 The reason for this is that CPAN does not know the dependencies of all
7111 modules when it starts out. To decide about the additional items to
7112 install, it just uses data found in the generated Makefile. An
7113 undetected missing piece breaks the process. But it may well be that
7114 your Bundle installs some prerequisite later than some depending item
7115 and thus your second try is able to resolve everything. Please note,
7116 CPAN.pm does not know the dependency tree in advance and cannot sort
7117 the queue of things to install in a topologically correct order. It
7118 resolves perfectly well IFF all modules declare the prerequisites
7119 correctly with the PREREQ_PM attribute to MakeMaker. For bundles which
7120 fail and you need to install often, it is recommended sort the Bundle
7121 definition file manually. It is planned to improve the metadata
7122 situation for dependencies on CPAN in general, but this will still
7127 In our intranet we have many modules for internal use. How
7128 can I integrate these modules with CPAN.pm but without uploading
7129 the modules to CPAN?
7131 Have a look at the CPAN::Site module.
7135 When I run CPAN's shell, I get error msg about line 1 to 4,
7136 setting meta input/output via the /etc/inputrc file.
7138 Some versions of readline are picky about capitalization in the
7139 /etc/inputrc file and specifically RedHat 6.2 comes with a
7140 /etc/inputrc that contains the word C<on> in lowercase. Change the
7141 occurrences of C<on> to C<On> and the bug should disappear.
7145 Some authors have strange characters in their names.
7147 Internally CPAN.pm uses the UTF-8 charset. If your terminal is
7148 expecting ISO-8859-1 charset, a converter can be activated by setting
7149 term_is_latin to a true value in your config file. One way of doing so
7152 cpan> ! $CPAN::Config->{term_is_latin}=1
7154 Extended support for converters will be made available as soon as perl
7155 becomes stable with regard to charset issues.
7161 We should give coverage for B<all> of the CPAN and not just the PAUSE
7162 part, right? In this discussion CPAN and PAUSE have become equal --
7163 but they are not. PAUSE is authors/, modules/ and scripts/. CPAN is
7164 PAUSE plus the clpa/, doc/, misc/, ports/, and src/.
7166 Future development should be directed towards a better integration of
7169 If a Makefile.PL requires special customization of libraries, prompts
7170 the user for special input, etc. then you may find CPAN is not able to
7171 build the distribution. In that case, you should attempt the
7172 traditional method of building a Perl module package from a shell.
