9735 The CPAN module automates or at least simplifies the make and install
9736 of perl modules and extensions. It includes some primitive searching
9737 capabilities and knows how to use Net::FTP or LWP or some external
9738 download clients to fetch the distributions from the net.
9740 These are fetched from one or more of the mirrored CPAN (Comprehensive
9741 Perl Archive Network) sites and unpacked in a dedicated directory.
9743 The CPAN module also supports the concept of named and versioned
9744 I<bundles> of modules. Bundles simplify the handling of sets of
9745 related modules. See Bundles below.
9747 The package contains a session manager and a cache manager. The
9748 session manager keeps track of what has been fetched, built and
9749 installed in the current session. The cache manager keeps track of the
9750 disk space occupied by the make processes and deletes excess space
9751 according to a simple FIFO mechanism.
9753 All methods provided are accessible in a programmer style and in an
9754 interactive shell style.
9756 =head2 CPAN::shell([$prompt, $command]) Starting Interactive Mode
9758 The interactive mode is entered by running
9760 perl -MCPAN -e shell
9766 which puts you into a readline interface. If C<Term::ReadKey> and
9767 either C<Term::ReadLine::Perl> or C<Term::ReadLine::Gnu> are installed
9768 it supports both history and command completion.
9770 Once you are on the command line, type C<h> to get a one page help
9771 screen and the rest should be self-explanatory.
9773 The function call C<shell> takes two optional arguments, one is the
9774 prompt, the second is the default initial command line (the latter
9775 only works if a real ReadLine interface module is installed).
9777 The most common uses of the interactive modes are
9781 =item Searching for authors, bundles, distribution files and modules
9783 There are corresponding one-letter commands C<a>, C<b>, C<d>, and C<m>
9784 for each of the four categories and another, C<i> for any of the
9785 mentioned four. Each of the four entities is implemented as a class
9786 with slightly differing methods for displaying an object.
9788 Arguments you pass to these commands are either strings exactly matching
9789 the identification string of an object or regular expressions that are
9790 then matched case-insensitively against various attributes of the
9791 objects. The parser recognizes a regular expression only if you
9792 enclose it between two slashes.
9794 The principle is that the number of found objects influences how an
9795 item is displayed. If the search finds one item, the result is
9796 displayed with the rather verbose method C<as_string>, but if we find
9797 more than one, we display each object with the terse method
9800 =item C<get>, C<make>, C<test>, C<install>, C<clean> modules or distributions
9802 These commands take any number of arguments and investigate what is
9803 necessary to perform the action. If the argument is a distribution
9804 file name (recognized by embedded slashes), it is processed. If it is
9805 a module, CPAN determines the distribution file in which this module
9806 is included and processes that, following any dependencies named in
9807 the module's META.yml or Makefile.PL (this behavior is controlled by
9808 the configuration parameter C<prerequisites_policy>.)
9810 C<get> downloads a distribution file and untars or unzips it, C<make>
9811 builds it, C<test> runs the test suite, and C<install> installs it.
9813 Any C<make> or C<test> are run unconditionally. An
9815 install <distribution_file>
9817 also is run unconditionally. But for
9821 CPAN checks if an install is actually needed for it and prints
9822 I<module up to date> in the case that the distribution file containing
9823 the module doesn't need to be updated.
9825 CPAN also keeps track of what it has done within the current session
9826 and doesn't try to build a package a second time regardless if it
9827 succeeded or not. It does not repeat a test run if the test
9828 has been run successfully before. Same for install runs.
9830 The C<force> pragma may precede another command (currently: C<get>,
9831 C<make>, C<test>, or C<install>) and executes the command from scratch
9832 and tries to continue in case of some errors. See the section below on
9833 the C<force> and the C<fforce> pragma.
9835 The C<notest> pragma may be used to skip the test part in the build
9840 cpan> notest install Tk
9842 A C<clean> command results in a
9846 being executed within the distribution file's working directory.
9848 =item C<readme>, C<perldoc>, C<look> module or distribution
9850 C<readme> displays the README file of the associated distribution.
9851 C<Look> gets and untars (if not yet done) the distribution file,
9852 changes to the appropriate directory and opens a subshell process in
9853 that directory. C<perldoc> displays the pod documentation of the
9854 module in html or plain text format.
9858 =item C<ls> globbing_expression
9860 The first form lists all distribution files in and below an author's
9861 CPAN directory as they are stored in the CHECKUMS files distributed on
9862 CPAN. The listing goes recursive into all subdirectories.
9864 The second form allows to limit or expand the output with shell
9865 globbing as in the following examples:
9871 The last example is very slow and outputs extra progress indicators
9872 that break the alignment of the result.
9874 Note that globbing only lists directories explicitly asked for, for
9875 example FOO/* will not list FOO/bar/Acme-Sthg-n.nn.tar.gz. This may be
9876 regarded as a bug and may be changed in future versions.
9880 The C<failed> command reports all distributions that failed on one of
9881 C<make>, C<test> or C<install> for some reason in the currently
9882 running shell session.
9884 =item Persistence between sessions
9886 If the C<YAML> or the c<YAML::Syck> module is installed a record of
9887 the internal state of all modules is written to disk after each step.
9888 The files contain a signature of the currently running perl version
9891 If the configurations variable C<build_dir_reuse> is set to a true
9892 value, then CPAN.pm reads the collected YAML files. If the stored
9893 signature matches the currently running perl the stored state is
9894 loaded into memory such that effectively persistence between sessions
9897 =item The C<force> and the C<fforce> pragma
9899 To speed things up in complex installation scenarios, CPAN.pm keeps
9900 track of what it has already done and refuses to do some things a
9901 second time. A C<get>, a C<make>, and an C<install> are not repeated.
9902 A C<test> is only repeated if the previous test was unsuccessful. The
9903 diagnostic message when CPAN.pm refuses to do something a second time
9904 is one of I<Has already been >C<unwrapped|made|tested successfully> or
9905 something similar. Another situation where CPAN refuses to act is an
9906 C<install> if the according C<test> was not successful.
9908 In all these cases, the user can override the goatish behaviour by
9909 prepending the command with the word force, for example:
9912 cpan> force make AUTHOR/Bar-3.14.tar.gz
9913 cpan> force test Baz
9914 cpan> force install Acme::Meta
9916 Each I<forced> command is executed with the according part of its
9919 The C<fforce> pragma is a variant that emulates a C<force get> which
9920 erases the entire memory followed by the action specified, effectively
9921 restarting the whole get/make/test/install procedure from scratch.
9925 Interactive sessions maintain a lockfile, per default C<~/.cpan/.lock>.
9926 Batch jobs can run without a lockfile and do not disturb each other.
9928 The shell offers to run in I<degraded mode> when another process is
9929 holding the lockfile. This is an experimental feature that is not yet
9930 tested very well. This second shell then does not write the history
9931 file, does not use the metadata file and has a different prompt.
9935 CPAN.pm installs signal handlers for SIGINT and SIGTERM. While you are
9936 in the cpan-shell it is intended that you can press C<^C> anytime and
9937 return to the cpan-shell prompt. A SIGTERM will cause the cpan-shell
9938 to clean up and leave the shell loop. You can emulate the effect of a
9939 SIGTERM by sending two consecutive SIGINTs, which usually means by
9940 pressing C<^C> twice.
9942 CPAN.pm ignores a SIGPIPE. If the user sets inactivity_timeout, a
9943 SIGALRM is used during the run of the C<perl Makefile.PL> or C<perl
9944 Build.PL> subprocess.
9950 The commands that are available in the shell interface are methods in
9951 the package CPAN::Shell. If you enter the shell command, all your
9952 input is split by the Text::ParseWords::shellwords() routine which
9953 acts like most shells do. The first word is being interpreted as the
9954 method to be called and the rest of the words are treated as arguments
9955 to this method. Continuation lines are supported if a line ends with a
9960 C<autobundle> writes a bundle file into the
9961 C<$CPAN::Config-E<gt>{cpan_home}/Bundle> directory. The file contains
9962 a list of all modules that are both available from CPAN and currently
9963 installed within @INC. The name of the bundle file is based on the
9964 current date and a counter.
9968 Note: this feature is still in alpha state and may change in future
9971 This commands provides a statistical overview over recent download
9972 activities. The data for this is collected in the YAML file
9973 C<FTPstats.yml> in your C<cpan_home> directory. If no YAML module is
9974 configured or YAML not installed, then no stats are provided.
9978 mkmyconfig() writes your own CPAN::MyConfig file into your ~/.cpan/
9979 directory so that you can save your own preferences instead of the
9984 recompile() is a very special command in that it takes no argument and
9985 runs the make/test/install cycle with brute force over all installed
9986 dynamically loadable extensions (aka XS modules) with 'force' in
9987 effect. The primary purpose of this command is to finish a network
9988 installation. Imagine, you have a common source tree for two different
9989 architectures. You decide to do a completely independent fresh
9990 installation. You start on one architecture with the help of a Bundle
9991 file produced earlier. CPAN installs the whole Bundle for you, but
9992 when you try to repeat the job on the second architecture, CPAN
9993 responds with a C<"Foo up to date"> message for all modules. So you
9994 invoke CPAN's recompile on the second architecture and you're done.
9996 Another popular use for C<recompile> is to act as a rescue in case your
9997 perl breaks binary compatibility. If one of the modules that CPAN uses
9998 is in turn depending on binary compatibility (so you cannot run CPAN
9999 commands), then you should try the CPAN::Nox module for recovery.
10001 =head2 report Bundle|Distribution|Module
10003 The C<report> command temporarily turns on the C<test_report> config
10004 variable, then runs the C<force test> command with the given
10005 arguments. The C<force> pragma is used to re-run the tests and repeat
10006 every step that might have failed before.
10008 =head2 upgrade [Module|/Regex/]...
10010 The C<upgrade> command first runs an C<r> command with the given
10011 arguments and then installs the newest versions of all modules that
10012 were listed by that.
10014 =head2 The four C<CPAN::*> Classes: Author, Bundle, Module, Distribution
10016 Although it may be considered internal, the class hierarchy does matter
10017 for both users and programmer. CPAN.pm deals with above mentioned four
10018 classes, and all those classes share a set of methods. A classical
10019 single polymorphism is in effect. A metaclass object registers all
10020 objects of all kinds and indexes them with a string. The strings
10021 referencing objects have a separated namespace (well, not completely
10026 words containing a "/" (slash) Distribution
10027 words starting with Bundle:: Bundle
10028 everything else Module or Author
10030 Modules know their associated Distribution objects. They always refer
10031 to the most recent official release. Developers may mark their releases
10032 as unstable development versions (by inserting an underbar into the
10033 module version number which will also be reflected in the distribution
10034 name when you run 'make dist'), so the really hottest and newest
10035 distribution is not always the default. If a module Foo circulates
10036 on CPAN in both version 1.23 and 1.23_90, CPAN.pm offers a convenient
10037 way to install version 1.23 by saying
10041 This would install the complete distribution file (say
10042 BAR/Foo-1.23.tar.gz) with all accompanying material. But if you would
10043 like to install version 1.23_90, you need to know where the
10044 distribution file resides on CPAN relative to the authors/id/
10045 directory. If the author is BAR, this might be BAR/Foo-1.23_90.tar.gz;
10046 so you would have to say
10048 install BAR/Foo-1.23_90.tar.gz
10050 The first example will be driven by an object of the class
10051 CPAN::Module, the second by an object of class CPAN::Distribution.
10053 =head2 Integrating local directories
10055 Note: this feature is still in alpha state and may change in future
10056 versions of CPAN.pm
10058 Distribution objects are normally distributions from the CPAN, but
10059 there is a slightly degenerate case for Distribution objects, too, of
10060 projects held on the local disk. These distribution objects have the
10061 same name as the local directory and end with a dot. A dot by itself
10062 is also allowed for the current directory at the time CPAN.pm was
10063 used. All actions such as C<make>, C<test>, and C<install> are applied
10064 directly to that directory. This gives the command C<cpan .> an
10065 interesting touch: while the normal mantra of installing a CPAN module
10066 without CPAN.pm is one of
10068 perl Makefile.PL perl Build.PL
10069 ( go and get prerequisites )
10071 make test ./Build test
10072 make install ./Build install
10074 the command C<cpan .> does all of this at once. It figures out which
10075 of the two mantras is appropriate, fetches and installs all
10076 prerequisites, cares for them recursively and finally finishes the
10077 installation of the module in the current directory, be it a CPAN
10080 The typical usage case is for private modules or working copies of
10081 projects from remote repositories on the local disk.
10083 =head1 CONFIGURATION
10085 When the CPAN module is used for the first time, a configuration
10086 dialog tries to determine a couple of site specific options. The
10087 result of the dialog is stored in a hash reference C< $CPAN::Config >
10088 in a file CPAN/Config.pm.
10090 The default values defined in the CPAN/Config.pm file can be
10091 overridden in a user specific file: CPAN/MyConfig.pm. Such a file is
10092 best placed in $HOME/.cpan/CPAN/MyConfig.pm, because $HOME/.cpan is
10093 added to the search path of the CPAN module before the use() or
10094 require() statements. The mkmyconfig command writes this file for you.
10096 The C<o conf> command has various bells and whistles:
10100 =item completion support
10102 If you have a ReadLine module installed, you can hit TAB at any point
10103 of the commandline and C<o conf> will offer you completion for the
10104 built-in subcommands and/or config variable names.
10106 =item displaying some help: o conf help
10108 Displays a short help
10110 =item displaying current values: o conf [KEY]
10112 Displays the current value(s) for this config variable. Without KEY
10113 displays all subcommands and config variables.
10119 =item changing of scalar values: o conf KEY VALUE
10121 Sets the config variable KEY to VALUE. The empty string can be
10122 specified as usual in shells, with C<''> or C<"">
10126 o conf wget /usr/bin/wget
10128 =item changing of list values: o conf KEY SHIFT|UNSHIFT|PUSH|POP|SPLICE|LIST
10130 If a config variable name ends with C<list>, it is a list. C<o conf
10131 KEY shift> removes the first element of the list, C<o conf KEY pop>
10132 removes the last element of the list. C<o conf KEYS unshift LIST>
10133 prepends a list of values to the list, C<o conf KEYS push LIST>
10134 appends a list of valued to the list.
10136 Likewise, C<o conf KEY splice LIST> passes the LIST to the according
10139 Finally, any other list of arguments is taken as a new list value for
10140 the KEY variable discarding the previous value.
10144 o conf urllist unshift http://cpan.dev.local/CPAN
10145 o conf urllist splice 3 1
10146 o conf urllist http://cpan1.local http://cpan2.local ftp://ftp.perl.org
10148 =item reverting to saved: o conf defaults
10150 Reverts all config variables to the state in the saved config file.
10152 =item saving the config: o conf commit
10154 Saves all config variables to the current config file (CPAN/Config.pm
10155 or CPAN/MyConfig.pm that was loaded at start).
10159 The configuration dialog can be started any time later again by
10160 issuing the command C< o conf init > in the CPAN shell. A subset of
10161 the configuration dialog can be run by issuing C<o conf init WORD>
10162 where WORD is any valid config variable or a regular expression.
10164 =head2 Config Variables
10166 Currently the following keys in the hash reference $CPAN::Config are

10264 =item C<o conf E<lt>scalar optionE<gt>>
10266 prints the current value of the I<scalar option>
10268 =item C<o conf E<lt>scalar optionE<gt> E<lt>valueE<gt>>

10285 =item interactive editing: o conf init [MATCH|LIST]
10287 Runs an interactive configuration dialog for matching variables.
10288 Without argument runs the dialog over all supported config variables.
10289 To specify a MATCH the argument must be enclosed by slashes.
10293 o conf init ftp_passive ftp_proxy
10294 o conf init /color/
10296 Note: this method of setting config variables often provides more
10297 explanation about the functioning of a variable than the manpage.
10301 =head2 CPAN::anycwd($path): Note on config variable getcwd
10303 CPAN.pm changes the current working directory often and needs to
10304 determine its own current working directory. Per default it uses
10305 Cwd::cwd but if this doesn't work on your system for some reason,
10306 alternatives can be configured according to the following table:
10324 Calls the external command cwd.
10328 =head2 Note on the format of the urllist parameter
10330 urllist parameters are URLs according to RFC 1738. We do a little
10331 guessing if your URL is not compliant, but if you have problems with
10332 C<file> URLs, please try the correct format. Either:
10334 file://localhost/whatever/ftp/pub/CPAN/
10338 file:///home/ftp/pub/CPAN/
10340 =head2 The urllist parameter has CD-ROM support
10342 The C<urllist> parameter of the configuration table contains a list of
10343 URLs that are to be used for downloading. If the list contains any
10344 C<file> URLs, CPAN always tries to get files from there first. This
10345 feature is disabled for index files. So the recommendation for the
10346 owner of a CD-ROM with CPAN contents is: include your local, possibly
10347 outdated CD-ROM as a C<file> URL at the end of urllist, e.g.
10349 o conf urllist push file://localhost/CDROM/CPAN
10351 CPAN.pm will then fetch the index files from one of the CPAN sites
10352 that come at the beginning of urllist. It will later check for each
10353 module if there is a local copy of the most recent version.
10355 Another peculiarity of urllist is that the site that we could
10356 successfully fetch the last file from automatically gets a preference
10357 token and is tried as the first site for the next request. So if you
10358 add a new site at runtime it may happen that the previously preferred
10359 site will be tried another time. This means that if you want to disallow
10360 a site for the next transfer, it must be explicitly removed from
10363 =head2 Maintaining the urllist parameter
10365 If you have YAML.pm (or some other YAML module configured in
10366 C<yaml_module>) installed, CPAN.pm collects a few statistical data
10367 about recent downloads. You can view the statistics with the C<hosts>
10368 command or inspect them directly by looking into the C<FTPstats.yml>
10369 file in your C<cpan_home> directory.
10371 To get some interesting statistics it is recommended to set the
10372 C<randomize_urllist> parameter that introduces some amount of
10373 randomness into the URL selection.
10375 =head2 The C<requires> and C<build_requires> dependency declarations
10377 Since CPAN.pm version 1.88_51 modules declared as C<build_requires> by
10378 a distribution are treated differently depending on the config
10379 variable C<build_requires_install_policy>. By setting
10380 C<build_requires_install_policy> to C<no> such a module is not being
10381 installed. It is only built and tested and then kept in the list of
10382 tested but uninstalled modules. As such it is available during the
10383 build of the dependent module by integrating the path to the
10384 C<blib/arch> and C<blib/lib> directories in the environment variable
10385 PERL5LIB. If C<build_requires_install_policy> is set ti C<yes>, then
10386 both modules declared as C<requires> and those declared as
10387 C<build_requires> are treated alike. By setting to C<ask/yes> or
10388 C<ask/no>, CPAN.pm asks the user and sets the default accordingly.
10390 =head2 Configuration for individual distributions (I<Distroprefs>)
10392 (B<Note:> This feature has been introduced in CPAN.pm 1.8854 and is
10393 still considered beta quality)
10395 Distributions on the CPAN usually behave according to what we call the
10396 CPAN mantra. Or since the event of Module::Build we should talk about
10399 perl Makefile.PL perl Build.PL
10401 make test ./Build test
10402 make install ./Build install
10404 But some modules cannot be built with this mantra. They try to get
10405 some extra data from the user via the environment, extra arguments or
10406 interactively thus disturbing the installation of large bundles like
10407 Phalanx100 or modules with many dependencies like Plagger.
10409 The distroprefs system of C<CPAN.pm> addresses this problem by
10410 allowing the user to specify extra informations and recipes in YAML
10417 pass additional arguments to one of the four commands,
10421 set environment variables
10425 instantiate an Expect object that reads from the console, waits for
10426 some regular expressions and enters some answers
10430 temporarily override assorted C<CPAN.pm> configuration variables
10434 disable the installation of an object altogether
10438 See the YAML and Data::Dumper files that come with the C<CPAN.pm>
10439 distribution in the C<distroprefs/> directory for examples.
10443 The YAML files themselves must have the C<.yml> extension, all other
10444 files are ignored (for two exceptions see I<Fallback Data::Dumper and
10445 Storable> below). The containing directory can be specified in
10446 C<CPAN.pm> in the C<prefs_dir> config variable. Try C<o conf init
10447 prefs_dir> in the CPAN shell to set and activate the distroprefs
10450 Every YAML file may contain arbitrary documents according to the YAML
10451 specification and every single document is treated as an entity that
10452 can specify the treatment of a single distribution.
10454 The names of the files can be picked freely, C<CPAN.pm> always reads
10455 all files (in alphabetical order) and takes the key C<match> (see
10456 below in I<Language Specs>) as a hashref containing match criteria
10457 that determine if the current distribution matches the YAML document
10460 =head2 Fallback Data::Dumper and Storable
10462 If neither your configured C<yaml_module> nor YAML.pm is installed
10463 CPAN.pm falls back to using Data::Dumper and Storable and looks for
10464 files with the extensions C<.dd> or C<.st> in the C<prefs_dir>
10465 directory. These files are expected to contain one or more hashrefs.
10466 For Data::Dumper generated files, this is expected to be done with by
10467 defining C<$VAR1>, C<$VAR2>, etc. The YAML shell would produce these
10470 ysh < somefile.yml > somefile.dd
10472 For Storable files the rule is that they must be constructed such that
10473 C<Storable::retrieve(file)> returns an array reference and the array
10474 elements represent one distropref object each. The conversion from
10475 YAML would look like so:
10477 perl -MYAML=LoadFile -MStorable=nstore -e '
10478 @y=LoadFile(shift);
10479 nstore(\@y, shift)' somefile.yml somefile.st
10481 In bootstrapping situations it is usually sufficient to translate only
10482 a few YAML files to Data::Dumper for the crucial modules like
10483 C<YAML::Syck>, C<YAML.pm> and C<Expect.pm>. If you prefer Storable
10484 over Data::Dumper, remember to pull out a Storable version that writes
10485 an older format than all the other Storable versions that will need to
10490 The following example contains all supported keywords and structures

10591 C<perl>, and C<perlconfig> that specify if a document is targeted at a
10592 specific CPAN distribution or installation.
10594 The corresponding values are interpreted as regular expressions. The
10595 C<distribution> related one will be matched against the canonical
10596 distribution name, e.g. "AUTHOR/Foo-Bar-3.14.tar.gz".
10598 The C<module> related one will be matched against I<all> modules
10599 contained in the distribution until one module matches.
10601 The C<perl> related one will be matched against C<$^X>.
10603 The value associated with C<perlconfig> is itself a hashref that is
10604 matched against corresponding values in the C<%Config::Config> hash
10605 living in the C< Config.pm > module.
10607 If more than one restriction of C<module>, C<distribution>, and
10608 C<perl> is specified, the results of the separately computed match
10609 values must all match. If this is the case then the hashref
10610 represented by the YAML document is returned as the preference
10611 structure for the current distribution.
10613 =item patches [array]
10615 An array of patches on CPAN or on the local disk to be applied in
10616 order via the external patch program. If the value for the C<-p>
10617 parameter is C<0> or C<1> is determined by reading the patch
10620 Note: if the C<applypatch> program is installed and C<CPAN::Config>
10621 knows about it B<and> a patch is written by the C<makepatch> program,
10622 then C<CPAN.pm> lets C<applypatch> apply the patch. Both C<makepatch>
10623 and C<applypatch> are available from CPAN in the C<JV/makepatch-*>
10628 Processing instructions for the C<perl Makefile.PL> or C<perl
10629 Build.PL> phase of the CPAN mantra. See below under I<Processiong
10634 Processing instructions for the C<make test> or C<./Build test> phase
10635 of the CPAN mantra. See below under I<Processiong Instructions>.
10639 =head2 Processing Instructions
10645 Arguments to be added to the command line
10649 A full commandline that will be executed as it stands by a system
10650 call. During the execution the environment variable PERL will is set
10651 to $^X. If C<commandline> is specified, the content of C<args> is not
10654 =item eexpect [hash]
10656 Extended C<expect>. This is a hash reference with three allowed keys,
10657 C<mode>, C<timeout>, and C<talk>.
10659 C<mode> may have the values C<deterministic> for the case where all
10660 questions come in the order written down and C<anyorder> for the case
10661 where the questions may come in any order. The default mode is
10664 C<timeout> denotes a timeout in seconds. Floating point timeouts are
10665 OK. In the case of a C<mode=deterministic> the timeout denotes the
10666 timeout per question, in the case of C<mode=anyorder> it denotes the
10667 timeout per byte received from the stream or questions.
10669 C<talk> is a reference to an array that contains alternating questions
10670 and answers. Questions are regular expressions and answers are literal
10671 strings. The Expect module will then watch the stream coming from the
10672 execution of the external program (C<perl Makefile.PL>, C<perl
10673 Build.PL>, C<make>, etc.).
10675 In the case of C<mode=deterministic> the CPAN.pm will inject the
10676 according answer as soon as the stream matches the regular expression.
10677 In the case of C<mode=anyorder> the CPAN.pm will answer a question as
10678 soon as the timeout is reached for the next byte in the input stream.
10679 In the latter case it removes the according question/answer pair from
10680 the array, so if you want to answer the question C<Do you really want
10681 to do that> several times, then it must be included in the array at
10682 least as often as you want this answer to be given.
10686 Environment variables to be set during the command
10688 =item expect [array]
10690 C<< expect: <array> >> is a short notation for
10693 mode: deterministic
10699 =head2 Schema verification with C<Kwalify>
10701 If you have the C<Kwalify> module installed (which is part of the
10702 Bundle::CPANxxl), then all your distroprefs files are checked for
10703 syntactical correctness.
10705 =head2 Example Distroprefs Files
10707 C<CPAN.pm> comes with a collection of example YAML files. Note that these
10708 are really just examples and should not be used without care because
10709 they cannot fit everybody's purpose. After all the authors of the
10710 packages that ask questions had a need to ask, so you should watch
10711 their questions and adjust the examples to your environment and your
10712 needs. You have beend warned:-)
10714 =head1 PROGRAMMER'S INTERFACE
10716 If you do not enter the shell, the available shell commands are both
10717 available as methods (C<CPAN::Shell-E<gt>install(...)>) and as
10718 functions in the calling package (C<install(...)>). Before calling low-level
10719 commands it makes sense to initialize components of CPAN you need, e.g.:
10721 CPAN::HandleConfig->load;
10722 CPAN::Shell::setup_output;
10723 CPAN::Index->reload;
10725 High-level commands do such initializations automatically.
10727 There's currently only one class that has a stable interface -
10728 CPAN::Shell. All commands that are available in the CPAN shell are
10729 methods of the class CPAN::Shell. Each of the commands that produce
10730 listings of modules (C<r>, C<autobundle>, C<u>) also return a list of
10731 the IDs of all modules within the list.
10735 =item expand($type,@things)
10737 The IDs of all objects available within a program are strings that can
10738 be expanded to the corresponding real objects with the
10739 C<CPAN::Shell-E<gt>expand("Module",@things)> method. Expand returns a
10740 list of CPAN::Module objects according to the C<@things> arguments
10741 given. In scalar context it only returns the first element of the
10744 =item expandany(@things)
10746 Like expand, but returns objects of the appropriate type, i.e.
10747 CPAN::Bundle objects for bundles, CPAN::Module objects for modules and
10748 CPAN::Distribution objects for distributions. Note: it does not expand
10749 to CPAN::Author objects.
10751 =item Programming Examples
10753 This enables the programmer to do operations that combine
10754 functionalities that are available in the shell.
10756 # install everything that is outdated on my disk:
10757 perl -MCPAN -e 'CPAN::Shell->install(CPAN::Shell->r)'
10759 # install my favorite programs if necessary:
10760 for $mod (qw(Net::FTP Digest::SHA Data::Dumper)){
10761 CPAN::Shell->install($mod);
10764 # list all modules on my disk that have no VERSION number
10765 for $mod (CPAN::Shell->expand("Module","/./")){
10766 next unless $mod->inst_file;
10767 # MakeMaker convention for undefined $VERSION:
10768 next unless $mod->inst_version eq "undef";
10769 print "No VERSION in ", $mod->id, "\n";
10772 # find out which distribution on CPAN contains a module:
10773 print CPAN::Shell->expand("Module","Apache::Constants")->cpan_file
10775 Or if you want to write a cronjob to watch The CPAN, you could list
10776 all modules that need updating. First a quick and dirty way:
10778 perl -e 'use CPAN; CPAN::Shell->r;'
10780 If you don't want to get any output in the case that all modules are
10781 up to date, you can parse the output of above command for the regular
10782 expression //modules are up to date// and decide to mail the output
10783 only if it doesn't match. Ick?
10785 If you prefer to do it more in a programmer style in one single
10786 process, maybe something like this suits you better:
10788 # list all modules on my disk that have newer versions on CPAN
10789 for $mod (CPAN::Shell->expand("Module","/./")){
10790 next unless $mod->inst_file;
10791 next if $mod->uptodate;
10792 printf "Module %s is installed as %s, could be updated to %s from CPAN\n",
10793 $mod->id, $mod->inst_version, $mod->cpan_version;
10796 If that gives you too much output every day, you maybe only want to
10797 watch for three modules. You can write
10799 for $mod (CPAN::Shell->expand("Module","/Apache|LWP|CGI/")){
10801 as the first line instead. Or you can combine some of the above
10804 # watch only for a new mod_perl module
10805 $mod = CPAN::Shell->expand("Module","mod_perl");
10806 exit if $mod->uptodate;
10807 # new mod_perl arrived, let me know all update recommendations

10856 do. Force takes as arguments a method name to be called and any number
10857 of additional arguments that should be passed to the called method.
10858 The internals of the object get the needed changes so that CPAN.pm
10859 does not refuse to take the action. The C<force> is passed recursively
10860 to all contained objects. See also the section above on the C<force>
10861 and the C<fforce> pragma.
10863 =item CPAN::Bundle::get()
10865 Recursively runs the C<get> method on all items contained in the bundle
10867 =item CPAN::Bundle::inst_file()
10869 Returns the highest installed version of the bundle in either @INC or

10871 CPAN::Module::inst_file.
10873 =item CPAN::Bundle::inst_version()
10875 Like CPAN::Bundle::inst_file, but returns the $VERSION
10877 =item CPAN::Bundle::uptodate()

10910 =item CPAN::Distribution::clean()
10912 Changes to the directory where the distribution has been unpacked and
10913 runs C<make clean> there.
10915 =item CPAN::Distribution::containsmods()
10917 Returns a list of IDs of modules contained in a distribution file.
10918 Only works for distributions listed in the 02packages.details.txt.gz
10919 file. This typically means that only the most recent version of a
10920 distribution is covered.
10922 =item CPAN::Distribution::cvs_import()
10924 Changes to the directory where the distribution has been unpacked and
10925 runs something like
10927 cvs -d $cvs_root import -m $cvs_log $cvs_dir $userid v$version
10931 =item CPAN::Distribution::dir()
10933 Returns the directory into which this distribution has been unpacked.
10935 =item CPAN::Distribution::force($method,@args)
10937 Forces CPAN to perform a task that it normally would have refused to
10938 do. Force takes as arguments a method name to be called and any number
10939 of additional arguments that should be passed to the called method.
10940 The internals of the object get the needed changes so that CPAN.pm
10941 does not refuse to take the action. See also the section above on the
10942 C<force> and the C<fforce> pragma.
10944 =item CPAN::Distribution::get()
10946 Downloads the distribution from CPAN and unpacks it. Does nothing if
10947 the distribution has already been downloaded and unpacked within the
10950 =item CPAN::Distribution::install()
10952 Changes to the directory where the distribution has been unpacked and
10953 runs the external command C<make install> there. If C<make> has not
10954 yet been run, it will be run first. A C<make test> will be issued in
10955 any case and if this fails, the install will be canceled. The
10956 cancellation can be avoided by letting C<force> run the C<install> for
10959 This install method has only the power to install the distribution if
10960 there are no dependencies in the way. To install an object and all of
10961 its dependencies, use CPAN::Shell->install.
10963 Note that install() gives no meaningful return value. See uptodate().
10965 =item CPAN::Distribution::install_tested()
10967 Install all the distributions that have been tested sucessfully but
10968 not yet installed. See also C<is_tested>.
10970 =item CPAN::Distribution::isa_perl()
10972 Returns 1 if this distribution file seems to be a perl distribution.
10973 Normally this is derived from the file name only, but the index from
10974 CPAN can contain a hint to achieve a return value of true for other
10977 =item CPAN::Distribution::is_tested()
10979 List all the distributions that have been tested sucessfully but not
10980 yet installed. See also C<install_tested>.
10982 =item CPAN::Distribution::look()
10984 Changes to the directory where the distribution has been unpacked and
10985 opens a subshell there. Exiting the subshell returns.
10987 =item CPAN::Distribution::make()
10989 First runs the C<get> method to make sure the distribution is
10990 downloaded and unpacked. Changes to the directory where the
10991 distribution has been unpacked and runs the external commands C<perl
10992 Makefile.PL> or C<perl Build.PL> and C<make> there.
10994 =item CPAN::Distribution::perldoc()
10996 Downloads the pod documentation of the file associated with a
10997 distribution (in html format) and runs it through the external
10998 command lynx specified in C<$CPAN::Config->{lynx}>. If lynx
10999 isn't available, it converts it to plain text with external
11000 command html2text and runs it through the pager specified
11001 in C<$CPAN::Config->{pager}>
11003 =item CPAN::Distribution::prefs()
11005 Returns the hash reference from the first matching YAML file that the
11006 user has deposited in the C<prefs_dir/> directory. The first
11007 succeeding match wins. The files in the C<prefs_dir/> are processed
11008 alphabetically and the canonical distroname (e.g.
11009 AUTHOR/Foo-Bar-3.14.tar.gz) is matched against the regular expressions
11010 stored in the $root->{match}{distribution} attribute value.
11011 Additionally all module names contained in a distribution are matched
11012 agains the regular expressions in the $root->{match}{module} attribute
11013 value. The two match values are ANDed together. Each of the two
11014 attributes are optional.
11016 =item CPAN::Distribution::prereq_pm()
11018 Returns the hash reference that has been announced by a distribution
11019 as the the C<requires> and C<build_requires> elements. These can be
11020 declared either by the C<META.yml> (if authoritative) or can be
11021 deposited after the run of C<Build.PL> in the file C<./_build/prereqs>
11022 or after the run of C<Makfile.PL> written as the C<PREREQ_PM> hash in
11023 a comment in the produced C<Makefile>. I<Note>: this method only works
11024 after an attempt has been made to C<make> the distribution. Returns
11027 =item CPAN::Distribution::readme()
11029 Downloads the README file associated with a distribution and runs it
11030 through the pager specified in C<$CPAN::Config->{pager}>.
11032 =item CPAN::Distribution::reports()
11034 Downloads report data for this distribution from cpantesters.perl.org
11035 and displays a subset of them.
11037 =item CPAN::Distribution::read_yaml()
11039 Returns the content of the META.yml of this distro as a hashref. Note:
11040 works only after an attempt has been made to C<make> the distribution.
11041 Returns undef otherwise. Also returns undef if the content of META.yml
11042 is not authoritative. (The rules about what exactly makes the content
11043 authoritative are still in flux.)
11045 =item CPAN::Distribution::test()
11047 Changes to the directory where the distribution has been unpacked and
11048 runs C<make test> there.
11050 =item CPAN::Distribution::uptodate()
11052 Returns 1 if all the modules contained in the distribution are
11053 uptodate. Relies on containsmods.
11055 =item CPAN::Index::force_reload()
11057 Forces a reload of all indices.
11059 =item CPAN::Index::reload()
11061 Reloads all indices if they have not been read for more than
11062 C<$CPAN::Config->{index_expire}> days.
11064 =item CPAN::InfoObj::dump()
11066 CPAN::Author, CPAN::Bundle, CPAN::Module, and CPAN::Distribution
11067 inherit this method. It prints the data structure associated with an
11068 object. Useful for debugging. Note: the data structure is considered
11069 internal and thus subject to change without notice.
11071 =item CPAN::Module::as_glimpse()
11073 Returns a one-line description of the module in four columns: The
11074 first column contains the word C<Module>, the second column consists
11075 of one character: an equals sign if this module is already installed
11076 and uptodate, a less-than sign if this module is installed but can be
11077 upgraded, and a space if the module is not installed. The third column
11078 is the name of the module and the fourth column gives maintainer or
11079 distribution information.
11081 =item CPAN::Module::as_string()
11083 Returns a multi-line description of the module
11085 =item CPAN::Module::clean()
11087 Runs a clean on the distribution associated with this module.
11089 =item CPAN::Module::cpan_file()

11095 Returns the latest version of this module available on CPAN.
11097 =item CPAN::Module::cvs_import()
11099 Runs a cvs_import on the distribution associated with this module.
11101 =item CPAN::Module::description()
11103 Returns a 44 character description of this module. Only available for
11104 modules listed in The Module List (CPAN/modules/00modlist.long.html
11105 or 00modlist.long.txt.gz)
11107 =item CPAN::Module::distribution()
11109 Returns the CPAN::Distribution object that contains the current
11110 version of this module.
11112 =item CPAN::Module::dslip_status()
11114 Returns a hash reference. The keys of the hash are the letters C<D>,
11115 C<S>, C<L>, C<I>, and <P>, for development status, support level,
11116 language, interface and public licence respectively. The data for the
11117 DSLIP status are collected by pause.perl.org when authors register
11118 their namespaces. The values of the 5 hash elements are one-character
11119 words whose meaning is described in the table below. There are also 5
11120 hash elements C<DV>, C<SV>, C<LV>, C<IV>, and <PV> that carry a more
11121 verbose value of the 5 status variables.
11123 Where the 'DSLIP' characters have the following meanings:

11166 =item CPAN::Module::force($method,@args)
11168 Forces CPAN to perform a task that it normally would have refused to
11169 do. Force takes as arguments a method name to be called and any number
11170 of additional arguments that should be passed to the called method.
11171 The internals of the object get the needed changes so that CPAN.pm
11172 does not refuse to take the action. See also the section above on the
11173 C<force> and the C<fforce> pragma.
11175 =item CPAN::Module::get()
11177 Runs a get on the distribution associated with this module.
11179 =item CPAN::Module::inst_file()
11181 Returns the filename of the module found in @INC. The first file found
11182 is reported just like perl itself stops searching @INC when it finds a
11185 =item CPAN::Module::available_file()
11187 Returns the filename of the module found in PERL5LIB or @INC. The
11188 first file found is reported. The advantage of this method over
11189 C<inst_file> is that modules that have been tested but not yet
11190 installed are included because PERL5LIB keeps track of tested modules.
11192 =item CPAN::Module::inst_version()
11194 Returns the version number of the installed module in readable format.
11196 =item CPAN::Module::available_version()
11198 Returns the version number of the available module in readable format.
11200 =item CPAN::Module::install()
11202 Runs an C<install> on the distribution associated with this module.
11204 =item CPAN::Module::look()
11206 Changes to the directory where the distribution associated with this
11207 module has been unpacked and opens a subshell there. Exiting the
11210 =item CPAN::Module::make()
11212 Runs a C<make> on the distribution associated with this module.
11214 =item CPAN::Module::manpage_headline()
11216 If module is installed, peeks into the module's manpage, reads the
11217 headline and returns it. Moreover, if the module has been downloaded
11218 within this session, does the equivalent on the downloaded module even
11219 if it is not installed.
11221 =item CPAN::Module::perldoc()
11223 Runs a C<perldoc> on this module.
11225 =item CPAN::Module::readme()
11227 Runs a C<readme> on the distribution associated with this module.
11229 =item CPAN::Module::reports()
11231 Calls the reports() method on the associated distribution object.
11233 =item CPAN::Module::test()
11235 Runs a C<test> on the distribution associated with this module.
11237 =item CPAN::Module::uptodate()
11239 Returns 1 if the module is installed and up-to-date.
11241 =item CPAN::Module::userid()
11243 Returns the author's ID of the module.
11247 =head2 Cache Manager
11249 Currently the cache manager only keeps track of the build directory
11250 ($CPAN::Config->{build_dir}). It is a simple FIFO mechanism that
11251 deletes complete directories below C<build_dir> as soon as the size of
11252 all directories there gets bigger than $CPAN::Config->{build_cache}
11253 (in MB). The contents of this cache may be used for later
11254 re-installations that you intend to do manually, but will never be
11255 trusted by CPAN itself. This is due to the fact that the user might
11256 use these directories for building modules on different architectures.
11258 There is another directory ($CPAN::Config->{keep_source_where}) where
11259 the original distribution files are kept. This directory is not
11260 covered by the cache manager and must be controlled by the user. If
11261 you choose to have the same directory as build_dir and as
11262 keep_source_where directory, then your sources will be deleted with
11263 the same fifo mechanism.
11267 A bundle is just a perl module in the namespace Bundle:: that does not
11268 define any functions or methods. It usually only contains documentation.
11270 It starts like a perl module with a package declaration and a $VERSION
11271 variable. After that the pod section looks like any other pod with the
11272 only difference being that I<one special pod section> exists starting with
11277 In this pod section each line obeys the format
11279 Module_Name [Version_String] [- optional text]
11281 The only required part is the first field, the name of a module
11282 (e.g. Foo::Bar, ie. I<not> the name of the distribution file). The rest
11283 of the line is optional. The comment part is delimited by a dash just
11284 as in the man page header.
11286 The distribution of a bundle should follow the same convention as
11287 other distributions.
11289 Bundles are treated specially in the CPAN package. If you say 'install
11290 Bundle::Tkkit' (assuming such a bundle exists), CPAN will install all
11291 the modules in the CONTENTS section of the pod. You can install your
11292 own Bundles locally by placing a conformant Bundle file somewhere into
11293 your @INC path. The autobundle() command which is available in the
11294 shell interface does that for you by including all currently installed
11295 modules in a snapshot bundle file.
11297 =head1 PREREQUISITES
11299 If you have a local mirror of CPAN and can access all files with
11300 "file:" URLs, then you only need a perl better than perl5.003 to run
11301 this module. Otherwise Net::FTP is strongly recommended. LWP may be
11302 required for non-UNIX systems or if your nearest CPAN site is
11303 associated with a URL that is not C<ftp:>.
11305 If you have neither Net::FTP nor LWP, there is a fallback mechanism
11306 implemented for an external ftp command or for an external lynx
11311 =head2 Finding packages and VERSION
11313 This module presumes that all packages on CPAN
11319 declare their $VERSION variable in an easy to parse manner. This
11320 prerequisite can hardly be relaxed because it consumes far too much
11321 memory to load all packages into the running program just to determine
11322 the $VERSION variable. Currently all programs that are dealing with
11323 version use something like this
11325 perl -MExtUtils::MakeMaker -le \
11326 'print MM->parse_version(shift)' filename
11328 If you are author of a package and wonder if your $VERSION can be
11329 parsed, please try the above method.
11333 come as compressed or gzipped tarfiles or as zip files and contain a
11334 C<Makefile.PL> or C<Build.PL> (well, we try to handle a bit more, but
11335 without much enthusiasm).
11341 The debugging of this module is a bit complex, because we have
11342 interferences of the software producing the indices on CPAN, of the
11343 mirroring process on CPAN, of packaging, of configuration, of
11344 synchronicity, and of bugs within CPAN.pm.
11346 For debugging the code of CPAN.pm itself in interactive mode some more
11347 or less useful debugging aid can be turned on for most packages within
11348 CPAN.pm with one of
11352 =item o debug package...
11354 sets debug mode for packages.
11356 =item o debug -package...
11358 unsets debug mode for packages.
11362 turns debugging on for all packages.
11364 =item o debug number
11368 which sets the debugging packages directly. Note that C<o debug 0>
11369 turns debugging off.
11371 What seems quite a successful strategy is the combination of C<reload
11372 cpan> and the debugging switches. Add a new debug statement while
11373 running in the shell and then issue a C<reload cpan> and see the new
11374 debugging messages immediately without losing the current context.
11376 C<o debug> without an argument lists the valid package names and the
11377 current set of packages in debugging mode. C<o debug> has built-in
11378 completion support.
11380 For debugging of CPAN data there is the C<dump> command which takes
11381 the same arguments as make/test/install and outputs each object's
11382 Data::Dumper dump. If an argument looks like a perl variable and
11383 contains one of C<$>, C<@> or C<%>, it is eval()ed and fed to
11384 Data::Dumper directly.
11386 =head2 Floppy, Zip, Offline Mode
11388 CPAN.pm works nicely without network too. If you maintain machines
11389 that are not networked at all, you should consider working with file:
11390 URLs. Of course, you have to collect your modules somewhere first. So
11391 you might use CPAN.pm to put together all you need on a networked
11392 machine. Then copy the $CPAN::Config->{keep_source_where} (but not
11393 $CPAN::Config->{build_dir}) directory on a floppy. This floppy is kind
11394 of a personal CPAN. CPAN.pm on the non-networked machines works nicely
11395 with this floppy. See also below the paragraph about CD-ROM support.
11397 =head2 Basic Utilities for Programmers
11401 =item has_inst($module)
11403 Returns true if the module is installed. Used to load all modules into
11404 the running CPAN.pm which are considered optional. The config variable
11405 C<dontload_list> can be used to intercept the C<has_inst()> call such
11406 that an optional module is not loaded despite being available. For
11407 example the following command will prevent that C<YAML.pm> is being
11410 cpan> o conf dontload_list push YAML
11412 See the source for details.
11414 =item has_usable($module)
11416 Returns true if the module is installed and is in a usable state. Only
11417 useful for a handful of modules that are used internally. See the
11418 source for details.
11420 =item instance($module)
11422 The constructor for all the singletons used to represent modules,
11423 distributions, authors and bundles. If the object already exists, this
11424 method returns the object, otherwise it calls the constructor.
11430 There's no strong security layer in CPAN.pm. CPAN.pm helps you to
11431 install foreign, unmasked, unsigned code on your machine. We compare
11432 to a checksum that comes from the net just as the distribution file
11433 itself. But we try to make it easy to add security on demand:
11435 =head2 Cryptographically signed modules
11437 Since release 1.77 CPAN.pm has been able to verify cryptographically
11438 signed module distributions using Module::Signature. The CPAN modules
11439 can be signed by their authors, thus giving more security. The simple
11440 unsigned MD5 checksums that were used before by CPAN protect mainly
11441 against accidental file corruption.
11443 You will need to have Module::Signature installed, which in turn
11444 requires that you have at least one of Crypt::OpenPGP module or the
11445 command-line F<gpg> tool installed.
11447 You will also need to be able to connect over the Internet to the public
11448 keyservers, like pgp.mit.edu, and their port 11731 (the HKP protocol).
11450 The configuration parameter check_sigs is there to turn signature
11451 checking on or off.
11455 Most functions in package CPAN are exported per default. The reason
11456 for this is that the primary use is intended for the cpan shell or for
11461 When the CPAN shell enters a subshell via the look command, it sets
11462 the environment CPAN_SHELL_LEVEL to 1 or increments it if it is
11465 When CPAN runs, it sets the environment variable PERL5_CPAN_IS_RUNNING.
11467 When the config variable ftp_passive is set, all downloads will be run
11468 with the environment variable FTP_PASSIVE set to this value. This is
11469 in general a good idea as it influences both Net::FTP and LWP based
11470 connections. The same effect can be achieved by starting the cpan
11471 shell with this environment variable set. For Net::FTP alone, one can
11472 also always set passive mode by running libnetcfg.
11474 =head1 POPULATE AN INSTALLATION WITH LOTS OF MODULES
11476 Populating a freshly installed perl with my favorite modules is pretty
11477 easy if you maintain a private bundle definition file. To get a useful
11478 blueprint of a bundle definition file, the command autobundle can be used
11479 on the CPAN shell command line. This command writes a bundle definition
11480 file for all modules that are installed for the currently running perl
11481 interpreter. It's recommended to run this command only once and from then
11482 on maintain the file manually under a private name, say
11483 Bundle/my_bundle.pm. With a clever bundle file you can then simply say
11485 cpan> install Bundle::my_bundle
11487 then answer a few questions and then go out for a coffee.
11489 Maintaining a bundle definition file means keeping track of two
11490 things: dependencies and interactivity. CPAN.pm sometimes fails on
11491 calculating dependencies because not all modules define all MakeMaker
11492 attributes correctly, so a bundle definition file should specify
11493 prerequisites as early as possible. On the other hand, it's a bit
11494 annoying that many distributions need some interactive configuring. So
11495 what I try to accomplish in my private bundle file is to have the
11496 packages that need to be configured early in the file and the gentle
11497 ones later, so I can go out after a few minutes and leave CPAN.pm
11500 =head1 WORKING WITH CPAN.pm BEHIND FIREWALLS
11502 Thanks to Graham Barr for contributing the following paragraphs about
11503 the interaction between perl, and various firewall configurations. For
11504 further information on firewalls, it is recommended to consult the
11505 documentation that comes with the ncftp program. If you are unable to
11506 go through the firewall with a simple Perl setup, it is very likely
11507 that you can configure ncftp so that it works for your firewall.
11509 =head2 Three basic types of firewalls
11511 Firewalls can be categorized into three basic types.
11515 =item http firewall
11517 This is where the firewall machine runs a web server and to access the
11518 outside world you must do it via the web server. If you set environment
11519 variables like http_proxy or ftp_proxy to a values beginning with http://
11520 or in your web browser you have to set proxy information then you know
11521 you are running an http firewall.
11523 To access servers outside these types of firewalls with perl (even for
11524 ftp) you will need to use LWP.
11528 This where the firewall machine runs an ftp server. This kind of
11529 firewall will only let you access ftp servers outside the firewall.
11530 This is usually done by connecting to the firewall with ftp, then
11531 entering a username like "user@outside.host.com"
11533 To access servers outside these type of firewalls with perl you
11534 will need to use Net::FTP.
11536 =item One way visibility
11538 I say one way visibility as these firewalls try to make themselves look
11539 invisible to the users inside the firewall. An FTP data connection is
11540 normally created by sending the remote server your IP address and then
11541 listening for the connection. But the remote server will not be able to
11542 connect to you because of the firewall. So for these types of firewall
11543 FTP connections need to be done in a passive mode.
11545 There are two that I can think off.
11551 If you are using a SOCKS firewall you will need to compile perl and link
11552 it with the SOCKS library, this is what is normally called a 'socksified'
11553 perl. With this executable you will be able to connect to servers outside
11554 the firewall as if it is not there.
11556 =item IP Masquerade
11558 This is the firewall implemented in the Linux kernel, it allows you to
11559 hide a complete network behind one IP address. With this firewall no
11560 special compiling is needed as you can access hosts directly.
11562 For accessing ftp servers behind such firewalls you usually need to
11563 set the environment variable C<FTP_PASSIVE> or the config variable
11564 ftp_passive to a true value.
11570 =head2 Configuring lynx or ncftp for going through a firewall
11572 If you can go through your firewall with e.g. lynx, presumably with a
11575 /usr/local/bin/lynx -pscott:tiger
11577 then you would configure CPAN.pm with the command
11579 o conf lynx "/usr/local/bin/lynx -pscott:tiger"
11581 That's all. Similarly for ncftp or ftp, you would configure something
11584 o conf ncftp "/usr/bin/ncftp -f /home/scott/ncftplogin.cfg"
11586 Your mileage may vary...
11594 I installed a new version of module X but CPAN keeps saying,
11595 I have the old version installed
11597 Most probably you B<do> have the old version installed. This can
11598 happen if a module installs itself into a different directory in the
11599 @INC path than it was previously installed. This is not really a
11600 CPAN.pm problem, you would have the same problem when installing the
11601 module manually. The easiest way to prevent this behaviour is to add
11602 the argument C<UNINST=1> to the C<make install> call, and that is why
11603 many people add this argument permanently by configuring
11605 o conf make_install_arg UNINST=1
11609 So why is UNINST=1 not the default?
11611 Because there are people who have their precise expectations about who
11612 may install where in the @INC path and who uses which @INC array. In
11613 fine tuned environments C<UNINST=1> can cause damage.
11617 I want to clean up my mess, and install a new perl along with
11618 all modules I have. How do I go about it?
11620 Run the autobundle command for your old perl and optionally rename the
11621 resulting bundle file (e.g. Bundle/mybundle.pm), install the new perl
11622 with the Configure option prefix, e.g.
11624 ./Configure -Dprefix=/usr/local/perl-5.6.78.9
11626 Install the bundle file you produced in the first step with something like
11628 cpan> install Bundle::mybundle
11634 When I install bundles or multiple modules with one command
11635 there is too much output to keep track of.
11637 You may want to configure something like
11639 o conf make_arg "| tee -ai /root/.cpan/logs/make.out"
11640 o conf make_install_arg "| tee -ai /root/.cpan/logs/make_install.out"
11642 so that STDOUT is captured in a file for later inspection.
11647 I am not root, how can I install a module in a personal directory?
11649 First of all, you will want to use your own configuration, not the one
11650 that your root user installed. If you do not have permission to write
11651 in the cpan directory that root has configured, you will be asked if
11652 you want to create your own config. Answering "yes" will bring you into
11653 CPAN's configuration stage, using the system config for all defaults except
11654 things that have to do with CPAN's work directory, saving your choices to
11655 your MyConfig.pm file.
11657 You can also manually initiate this process with the following command:
11659 % perl -MCPAN -e 'mkmyconfig'
11665 from the CPAN shell.
11667 You will most probably also want to configure something like this:
11669 o conf makepl_arg "LIB=~/myperl/lib \
11670 INSTALLMAN1DIR=~/myperl/man/man1 \
11671 INSTALLMAN3DIR=~/myperl/man/man3 \
11672 INSTALLSCRIPT=~/myperl/bin \
11673 INSTALLBIN=~/myperl/bin"
11675 and then (oh joy) the equivalent command for Module::Build.
11677 You can make this setting permanent like all C<o conf> settings with
11678 C<o conf commit> or by setting C<auto_commit> beforehand.
11680 You will have to add ~/myperl/man to the MANPATH environment variable
11681 and also tell your perl programs to look into ~/myperl/lib, e.g. by
11684 use lib "$ENV{HOME}/myperl/lib";
11686 or setting the PERL5LIB environment variable.
11688 While we're speaking about $ENV{HOME}, it might be worth mentioning,
11689 that for Windows we use the File::HomeDir module that provides an
11690 equivalent to the concept of the home directory on Unix.
11692 Another thing you should bear in mind is that the UNINST parameter can
11693 be dnagerous when you are installing into a private area because you
11694 might accidentally remove modules that other people depend on that are
11695 not using the private area.
11699 How to get a package, unwrap it, and make a change before building it?
11701 Have a look at the C<look> (!) command.
11705 I installed a Bundle and had a couple of fails. When I
11706 retried, everything resolved nicely. Can this be fixed to work
11709 The reason for this is that CPAN does not know the dependencies of all
11710 modules when it starts out. To decide about the additional items to
11711 install, it just uses data found in the META.yml file or the generated
11712 Makefile. An undetected missing piece breaks the process. But it may
11713 well be that your Bundle installs some prerequisite later than some
11714 depending item and thus your second try is able to resolve everything.
11715 Please note, CPAN.pm does not know the dependency tree in advance and
11716 cannot sort the queue of things to install in a topologically correct
11717 order. It resolves perfectly well IF all modules declare the
11718 prerequisites correctly with the PREREQ_PM attribute to MakeMaker or
11719 the C<requires> stanza of Module::Build. For bundles which fail and
11720 you need to install often, it is recommended to sort the Bundle
11721 definition file manually.
11725 In our intranet we have many modules for internal use. How
11726 can I integrate these modules with CPAN.pm but without uploading
11727 the modules to CPAN?
11729 Have a look at the CPAN::Site module.
11733 When I run CPAN's shell, I get an error message about things in my
11734 /etc/inputrc (or ~/.inputrc) file.
11736 These are readline issues and can only be fixed by studying readline
11737 configuration on your architecture and adjusting the referenced file
11738 accordingly. Please make a backup of the /etc/inputrc or ~/.inputrc
11739 and edit them. Quite often harmless changes like uppercasing or
11740 lowercasing some arguments solves the problem.
11744 Some authors have strange characters in their names.
11746 Internally CPAN.pm uses the UTF-8 charset. If your terminal is
11747 expecting ISO-8859-1 charset, a converter can be activated by setting
11748 term_is_latin to a true value in your config file. One way of doing so
11751 cpan> o conf term_is_latin 1
11753 If other charset support is needed, please file a bugreport against
11754 CPAN.pm at rt.cpan.org and describe your needs. Maybe we can extend
11755 the support or maybe UTF-8 terminals become widely available.
11759 When an install fails for some reason and then I correct the error
11760 condition and retry, CPAN.pm refuses to install the module, saying
11761 C<Already tried without success>.
11763 Use the force pragma like so
11765 force install Foo::Bar
11771 and then 'make install' directly in the subshell.
11775 How do I install a "DEVELOPER RELEASE" of a module?
11777 By default, CPAN will install the latest non-developer release of a
11778 module. If you want to install a dev release, you have to specify the
11779 partial path starting with the author id to the tarball you wish to
11782 cpan> install KWILLIAMS/Module-Build-0.27_07.tar.gz
11784 Note that you can use the C<ls> command to get this path listed.
11788 How do I install a module and all its dependencies from the commandline,
11789 without being prompted for anything, despite my CPAN configuration
11792 CPAN uses ExtUtils::MakeMaker's prompt() function to ask its questions, so
11793 if you set the PERL_MM_USE_DEFAULT environment variable, you shouldn't be
11794 asked any questions at all (assuming the modules you are installing are
11795 nice about obeying that variable as well):
11797 % PERL_MM_USE_DEFAULT=1 perl -MCPAN -e 'install My::Module'
11801 How do I create a Module::Build based Build.PL derived from an
11802 ExtUtils::MakeMaker focused Makefile.PL?
11804 http://search.cpan.org/search?query=Module::Build::Convert
11806 http://www.refcnt.org/papers/module-build-convert
11810 What's the best CPAN site for me?
11812 The urllist config parameter is yours. You can add and remove sites at
11813 will. You should find out which sites have the best uptodateness,
11814 bandwidth, reliability, etc. and are topologically close to you. Some
11815 people prefer fast downloads, others uptodateness, others reliability.
11816 You decide which to try in which order.
11818 Henk P. Penning maintains a site that collects data about CPAN sites:
11820 http://www.cs.uu.nl/people/henkp/mirmon/cpan.html
11824 =head1 COMPATIBILITY
11826 =head2 OLD PERL VERSIONS
11828 CPAN.pm is regularly tested to run under 5.004, 5.005, and assorted
11829 newer versions. It is getting more and more difficult to get the
11830 minimal prerequisites working on older perls. It is close to
11831 impossible to get the whole Bundle::CPAN working there. If you're in
11832 the position to have only these old versions, be advised that CPAN is
11833 designed to work fine without the Bundle::CPAN installed.
11835 To get things going, note that GBARR/Scalar-List-Utils-1.18.tar.gz is
11836 compatible with ancient perls and that File::Temp is listed as a
11837 prerequisite but CPAN has reasonable workarounds if it is missing.
11841 This module and its competitor, the CPANPLUS module, are both much
11842 cooler than the other. CPAN.pm is older. CPANPLUS was designed to be
11843 more modular but it was never tried to make it compatible with CPAN.pm.
