From ae97ca0e66ebf42663eb050764ab979e3ae95815 Mon Sep 17 00:00:00 2001 From: "Flavio S. Glock" Date: Sat, 14 Mar 2026 10:44:25 +0100 Subject: [PATCH 01/17] CPAN Phase 6: Add Safe.pm stub and import CPAN.pm (WIP) Phase 6a: Safe.pm stub - Created Safe.pm stub that uses regular eval instead of sandboxing - Sufficient for CPAN.pm which uses Safe to eval trusted metadata Phase 6c: Import CPAN.pm and dependencies - Added CPAN.pm and all CPAN/* modules via sync.pl - Added CPAN::Meta, CPAN::Meta::YAML, CPAN::Meta::Requirements - Added Parse::CPAN::Meta Other changes: - Import original Cwd.pm from perl5 (has pure Perl fallbacks) - Created stub Cwd.java for XSLoader compatibility - Fixed parser bug: -f ($x = $path) now parses correctly (file test operators with assignment inside parentheses) Still needed: - POSIX :sys_wait_h export tag - Module::Build stub - Try::Tiny compatibility shim - Testing and documentation Generated with [Devin](https://cli.devin.ai/docs) Co-Authored-By: Devin --- dev/import-perl5/config.yaml | 37 +

# same thing + +=head1 DESCRIPTION + +The CPAN module automates or at least simplifies the make and install +of perl modules and extensions. It includes some primitive searching +capabilities and knows how to use LWP, HTTP::Tiny, Net::FTP and certain +external download clients to fetch distributions from the net. + +These are fetched from one or more mirrored CPAN (Comprehensive +Perl Archive Network) sites and unpacked in a dedicated directory. + +The CPAN module also supports named and versioned +I of modules. Bundles simplify handling of sets of +related modules. See Bundles below. + +The package contains a session manager and a cache manager. The +session manager keeps track of what has been fetched, built, and +installed in the current session. The cache manager keeps track of the +disk space occupied by the make processes and deletes excess space +using a simple FIFO mechanism. + +All methods provided are accessible in a programmer style and in an +interactive shell style. + +=head2 CPAN::shell([$prompt, $command]) Starting Interactive Mode + +Enter interactive mode by running + + perl -MCPAN -e shell + +or + + cpan + +which puts you into a readline interface. If C and +either of C or C are installed, +history and command completion are supported. + +Once at the command line, type C for one-page help +screen; the rest should be self-explanatory. + +The function call C takes two optional arguments: one the +prompt, the second the default initial command line (the latter +only works if a real ReadLine interface module is installed). + +The most common uses of the interactive modes are + +=over 2 + +=item Searching for authors, bundles, distribution files and modules + +There are corresponding one-letter commands C, C, C, and C +for each of the four categories and another, C for any of the +mentioned four. Each of the four entities is implemented as a class +with slightly differing methods for displaying an object. + +Arguments to these commands are either strings exactly matching +the identification string of an object, or regular expressions +matched case-insensitively against various attributes of the +objects. The parser only recognizes a regular expression when you +enclose it with slashes. + +The principle is that the number of objects found influences how an +item is displayed. If the search finds one item, the result is +displayed with the rather verbose method C, but if +more than one is found, each object is displayed with the terse method +C. + +Examples: + + cpan> m Acme::MetaSyntactic + Module id = Acme::MetaSyntactic + CPAN_USERID BOOK (Philippe Bruhat (BooK) <[...]>) + CPAN_VERSION 0.99 + CPAN_FILE B/BO/BOOK/Acme-MetaSyntactic-0.99.tar.gz + UPLOAD_DATE 2006-11-06 + MANPAGE Acme::MetaSyntactic - Themed metasyntactic variables names + INST_FILE /usr/local/lib/perl/5.10.0/Acme/MetaSyntactic.pm + INST_VERSION 0.99 + cpan> a BOOK + Author id = BOOK + EMAIL [...] + FULLNAME Philippe Bruhat (BooK) + cpan> d BOOK/Acme-MetaSyntactic-0.99.tar.gz + Distribution id = B/BO/BOOK/Acme-MetaSyntactic-0.99.tar.gz + CPAN_USERID BOOK (Philippe Bruhat (BooK) <[...]>) + CONTAINSMODS Acme::MetaSyntactic Acme::MetaSyntactic::Alias [...] + UPLOAD_DATE 2006-11-06 + cpan> m /lorem/ + Module = Acme::MetaSyntactic::loremipsum (BOOK/Acme-MetaSyntactic-0.99.tar.gz) + Module Text::Lorem (ADEOLA/Text-Lorem-0.3.tar.gz) + Module Text::Lorem::More (RKRIMEN/Text-Lorem-More-0.12.tar.gz) + Module Text::Lorem::More::Source (RKRIMEN/Text-Lorem-More-0.12.tar.gz) + cpan> i /berlin/ + Distribution BEATNIK/Filter-NumberLines-0.02.tar.gz + Module = DateTime::TimeZone::Europe::Berlin (DROLSKY/DateTime-TimeZone-0.7904.tar.gz) + Module Filter::NumberLines (BEATNIK/Filter-NumberLines-0.02.tar.gz) + Author [...] + +The examples illustrate several aspects: the first three queries +target modules, authors, or distros directly and yield exactly one +result. The last two use regular expressions and yield several +results. The last one targets all of bundles, modules, authors, and +distros simultaneously. When more than one result is available, they +are printed in one-line format. + +=item C, C, C, C, C modules or distributions + +These commands take any number of arguments and investigate what is +necessary to perform the action. Argument processing is as follows: + + known module name in format Foo/Bar.pm module + other embedded slash distribution + - with trailing slash dot directory + enclosing slashes regexp + known module name in format Foo::Bar module + +If the argument is a distribution file name (recognized by embedded +slashes), it is processed. If it is a module, CPAN determines the +distribution file in which this module is included and processes that, +following any dependencies named in the module's META.yml or +Makefile.PL (this behavior is controlled by the configuration +parameter C). If an argument is enclosed in +slashes it is treated as a regular expression: it is expanded and if +the result is a single object (distribution, bundle or module), this +object is processed. + +Example: + + install Dummy::Perl # installs the module + install AUXXX/Dummy-Perl-3.14.tar.gz # installs that distribution + install /Dummy-Perl-3.14/ # same if the regexp is unambiguous + +C downloads a distribution file and untars or unzips it, C +builds it, C runs the test suite, and C installs it. + +Any C or C is run unconditionally. An + + install + +is also run unconditionally. But for + + install + +CPAN checks whether an install is needed and prints +I if the distribution file containing +the module doesn't need updating. + +CPAN also keeps track of what it has done within the current session +and doesn't try to build a package a second time regardless of whether it +succeeded or not. It does not repeat a test run if the test +has been run successfully before. Same for install runs. + +The C pragma may precede another command (currently: C, +C, C, or C) to execute the command from scratch +and attempt to continue past certain errors. See the section below on +the C and the C pragma. + +The C pragma skips the test part in the build +process. + +Example: + + cpan> notest install Tk + +A C command results in a + + make clean + +being executed within the distribution file's working directory. + +=item C, C, C module or distribution + +C displays the README file of the associated distribution. +C gets and untars (if not yet done) the distribution file, +changes to the appropriate directory and opens a subshell process in +that directory. C displays the module's pod documentation +in html or plain text format. + +=item C author + +=item C globbing_expression + +The first form lists all distribution files in and below an author's +CPAN directory as stored in the CHECKSUMS files distributed on +CPAN. The listing recurses into subdirectories. + +The second form limits or expands the output with shell +globbing as in the following examples: + + ls JV/make* + ls GSAR/*make* + ls */*make* + +The last example is very slow and outputs extra progress indicators +that break the alignment of the result. + +Note that globbing only lists directories explicitly asked for, for +example FOO/* will not list FOO/bar/Acme-Sthg-n.nn.tar.gz. This may be +regarded as a bug that may be changed in some future version. + +=item C + +The C command reports all distributions that failed on one of +C, C or C for some reason in the currently +running shell session. + +=item Persistence between sessions + +If the C or the C module is installed a record of +the internal state of all modules is written to disk after each step. +The files contain a signature of the currently running perl version +for later perusal. + +If the configurations variable C is set to a true +value, then CPAN.pm reads the collected YAML files. If the stored +signature matches the currently running perl, the stored state is +loaded into memory such that persistence between sessions +is effectively established. + +=item The C and the C pragma + +To speed things up in complex installation scenarios, CPAN.pm keeps +track of what it has already done and refuses to do some things a +second time. A C, a C, and an C are not repeated. +A C is repeated only if the previous test was unsuccessful. The +diagnostic message when CPAN.pm refuses to do something a second time +is one of IC or +something similar. Another situation where CPAN refuses to act is an +C if the corresponding C was not successful. + +In all these cases, the user can override this stubborn behaviour by +prepending the command with the word force, for example: + + cpan> force get Foo + cpan> force make AUTHOR/Bar-3.14.tar.gz + cpan> force test Baz + cpan> force install Acme::Meta + +Each I command is executed with the corresponding part of its +memory erased. + +The C pragma is a variant that emulates a C which +erases the entire memory followed by the action specified, effectively +restarting the whole get/make/test/install procedure from scratch. + +=item Lockfile + +Interactive sessions maintain a lockfile, by default C<~/.cpan/.lock>. +Batch jobs can run without a lockfile and not disturb each other. + +The shell offers to run in I when another process is +holding the lockfile. This is an experimental feature that is not yet +tested very well. This second shell then does not write the history +file, does not use the metadata file, and has a different prompt. + +=item Signals + +CPAN.pm installs signal handlers for SIGINT and SIGTERM. While you are +in the cpan-shell, it is intended that you can press C<^C> anytime and +return to the cpan-shell prompt. A SIGTERM will cause the cpan-shell +to clean up and leave the shell loop. You can emulate the effect of a +SIGTERM by sending two consecutive SIGINTs, which usually means by +pressing C<^C> twice. + +CPAN.pm ignores SIGPIPE. If the user sets C, a +SIGALRM is used during the run of the C or C subprocess. A SIGALRM is also used during module version +parsing, and is controlled by C. + +=back + +=head2 CPAN::Shell + +The commands available in the shell interface are methods in +the package CPAN::Shell. If you enter the shell command, your +input is split by the Text::ParseWords::shellwords() routine, which +acts like most shells do.

You decide to do a completely independent fresh +installation. You start on one architecture with the help of a Bundle +file produced earlier. CPAN installs the whole Bundle for you, but +when you try to repeat the job on the second architecture, CPAN +responds with a C<"Foo up to date"> message for all modules. So you +invoke CPAN's recompile on the second architecture and you're done. + +Another popular use for C is to act as a rescue in case your +perl breaks binary compatibility. If one of the modules that CPAN uses +is in turn depending on binary compatibility (so you cannot run CPAN +commands), then you should try the CPAN::Nox module for recovery. + +=head2 report Bundle|Distribution|Module + +The C command temporarily turns on the C config +variable, then runs the C command with the given +arguments.

While the +command is running $SIG{INT} is defined to mean that the current item +shall be skipped. + +B: This whole command currently is just a hack and will +probably change in future versions of CPAN.pm, but the general +approach will likely remain. + +B: See also L + +=head2 upgrade [Module|/Regexp/]... + +The C command first runs an C command with the given +arguments and then installs the newest versions of all modules that +were listed by that. + +=head2 The four C Classes: Author, Bundle, Module, Distribution + +Although it may be considered internal, the class hierarchy does matter +for both users and programmer. CPAN.pm deals with the four +classes mentioned above, and those classes all share a set of methods. Classical +single polymorphism is in effect. A metaclass object registers all +objects of all kinds and indexes them with a string. The strings +referencing objects have a separated namespace (well, not completely +separated): + + Namespace Class + + words containing a "/" (slash) Distribution + words starting with Bundle:: Bundle + everything else Module or Author + +Modules know their associated Distribution objects. They always refer +to the most recent official release. Developers may mark their releases +as unstable development versions (by inserting an underscore into the +module version number which will also be reflected in the distribution +name when you run 'make dist'), so the really hottest and newest +distribution is not always the default. If a module Foo circulates +on CPAN in both version 1.23 and 1.23_90, CPAN.pm offers a convenient +way to install version 1.23 by saying + + install Foo + +This would install the complete distribution file (say +BAR/Foo-1.23.tar.gz) with all accompanying material. But if you would +like to install version 1.23_90, you need to know where the +distribution file resides on CPAN relative to the authors/id/ +directory. If the author is BAR, this might be BAR/Foo-1.23_90.tar.gz; +so you would have to say + + install BAR/Foo-1.23_90.tar.gz + +The first example will be driven by an object of the class +CPAN::Module, the second by an object of class CPAN::Distribution. + +=head2 Integrating local directories + +Note: this feature is still in alpha state and may change in future +versions of CPAN.pm + +Distribution objects are normally distributions from the CPAN, but +there is a slightly degenerate case for Distribution objects, too, of +projects held on the local disk. These distribution objects have the +same name as the local directory and end with a dot. A dot by itself +is also allowed for the current directory at the time CPAN.pm was +used. All actions such as C, C, and C are applied +directly to that directory. This gives the command C an +interesting touch: while the normal mantra of installing a CPAN module +without CPAN.pm is one of + + perl Makefile.PL perl Build.PL + ( go and get prerequisites ) + make ./Build + make test ./Build test + make install ./Build install + +the command C does all of this at once. It figures out which +of the two mantras is appropriate, fetches and installs all +prerequisites, takes care of them recursively, and finally finishes the +installation of the module in the current directory, be it a CPAN +module or not. + +The typical usage case is for private modules or working copies of +projects from remote repositories on the local disk. + +=head2 Redirection + +The usual shell redirection symbols C< | > and C<< > >> are recognized +by the cpan shell B. So piping to +pager or redirecting output into a file works somewhat as in a normal +shell, with the stipulation that you must type extra spaces. + +=head2 Plugin support ***EXPERIMENTAL*** + +Plugins are objects that implement any of currently eight methods: + + pre_get + post_get + pre_make + post_make + pre_test + post_test + pre_install + post_install + +The C configuration parameter holds a list of strings of +the form + + Modulename=arg0,arg1,arg2,arg3,... + +eg: + + CPAN::Plugin::Flurb=dir,/opt/pkgs/flurb/raw,verbose,1 + +At run time, each listed plugin is instantiated as a singleton object +by running the equivalent of this pseudo code: + + my $plugin = ; + ; + my $p = $instance{$plugin} ||= Modulename->new($arg0,$arg1,...); + +The generated singletons are kept around from instantiation until the +end of the shell session. can be reconfigured at any +time at run time. While the cpan shell is running, it checks all +activated plugins at each of the 8 reference points listed above and +runs the respective method if it is implemented for that object. The +method is called with the active CPAN::Distribution object passed in +as an argument. + +=head1 CONFIGURATION + +When the CPAN module is used for the first time, a configuration +dialogue tries to determine a couple of site specific options. The +result of the dialog is stored in a hash reference C< $CPAN::Config > +in a file CPAN/Config.pm. + +Default values defined in the CPAN/Config.pm file can be +overridden in a user specific file: CPAN/MyConfig.pm. Such a file is +best placed in C<$HOME/.cpan/CPAN/MyConfig.pm>, because C<$HOME/.cpan> is +added to the search path of the CPAN module before the use() or +require() statements. The mkmyconfig command writes this file for you. + +If you want to keep your own CPAN/MyConfig.pm somewhere else, you +should load it before loading CPAN.pm, e.g.: + + perl -I/tmp/somewhere -MCPAN::MyConfig -MCPAN -eshell + + --or-- + + perl -I/tmp/somewhere -MCPAN::MyConfig -S cpan + +Once you are in the shell you can change your configuration as follows. + +The C command has various bells and whistles: + +=over + +=item completion support + +If you have a ReadLine module installed, you can hit TAB at any point +of the commandline and C will offer you completion for the +built-in subcommands and/or config variable names. + +=item displaying some help: o conf help + +Displays a short help + +=item displaying current values: o conf [KEY] + +Displays the current value(s) for this config variable.

Either: + + file://localhost/whatever/ftp/pub/CPAN/ + +or + + file:///home/ftp/pub/CPAN/ + +=head2 The urllist parameter has CD-ROM support + +The C parameter of the configuration table contains a list of +URLs used for downloading. If the list contains any +C URLs, CPAN always tries there first. This +feature is disabled for index files. So the recommendation for the +owner of a CD-ROM with CPAN contents is: include your local, possibly +outdated CD-ROM as a C URL at the end of urllist, e.g. + + o conf urllist push file://localhost/CDROM/CPAN + +CPAN.pm will then fetch the index files from one of the CPAN sites +that come at the beginning of urllist. It will later check for each +module to see whether there is a local copy of the most recent version. + +Another peculiarity of urllist is that the site that we could +successfully fetch the last file from automatically gets a preference +token and is tried as the first site for the next request. So if you +add a new site at runtime it may happen that the previously preferred +site will be tried another time. This means that if you want to disallow +a site for the next transfer, it must be explicitly removed from +urllist. + +=head2 Maintaining the urllist parameter + +If you have YAML.pm (or some other YAML module configured in +C) installed, CPAN.pm collects a few statistical data +about recent downloads. You can view the statistics with the C +command or inspect them directly by looking into the C +file in your C directory. + +To get some interesting statistics, it is recommended that +C be set; this introduces some amount of +randomness into the URL selection. + +=head2 The C and C dependency declarations + +Since CPAN.pm version 1.88_51 modules declared as C by +a distribution are treated differently depending on the config +variable C. By setting +C to C, such a module is not +installed. It is only built and tested, and then kept in the list of +tested but uninstalled modules. As such, it is available during the +build of the dependent module by integrating the path to the +C and C directories in the environment variable +PERL5LIB. If C is set to C, then +both modules declared as C and those declared as +C are treated alike. By setting to C or +C, CPAN.pm asks the user and sets the default accordingly. + +=head2 Configuration of the allow_installing_* parameters + +The C parameters are evaluated during +the C phase. If set to C, they allow the testing and the installation of +the current distro and otherwise have no effect. If set to C, they +may abort the build (preventing testing and installing), depending on the contents of the +C directory. The C directory is the directory that holds +all the files that would usually be installed in the C phase. + +C compares the C directory with the CPAN index. +If it finds something there that belongs, according to the index, to a different +dist, it aborts the current build. + +C compares the C directory +with already installed modules, actually their version numbers, as +determined by ExtUtils::MakeMaker or equivalent. If a to-be-installed +module would downgrade an already installed module, the current build +is aborted. + +An interesting twist occurs when a distroprefs document demands the +installation of an outdated dist via goto while +C forbids it. Without additional +provisions, this would let the C +win and the distroprefs lose. So the proper arrangement in such a case +is to write a second distroprefs document for the distro that C +points to and overrule the C there. E.g.: + + --- + match: + distribution: "^MAUKE/Keyword-Simple-0.04.tar.gz" + goto: "MAUKE/Keyword-Simple-0.03.tar.gz" + --- + match: + distribution: "^MAUKE/Keyword-Simple-0.03.tar.gz" + cpanconfig: + allow_installing_outdated_dists: yes + +=head2 Configuration for individual distributions (I) + +(B This feature has been introduced in CPAN.pm 1.8854) + +Distributions on CPAN usually behave according to what we call the +CPAN mantra. Or since the advent of Module::Build we should talk about +two mantras: + + perl Makefile.PL perl Build.PL + make ./Build + make test ./Build test + make install ./Build install + +But some modules cannot be built with this mantra. They try to get +some extra data from the user via the environment, extra arguments, or +interactively--thus disturbing the installation of large bundles like +Phalanx100 or modules with many dependencies like Plagger. + +The distroprefs system of C addresses this problem by +allowing the user to specify extra informations and recipes in YAML +files to either + +=over + +=item + +pass additional arguments to one of the four commands, + +=item + +set environment variables + +=item + +instantiate an Expect object that reads from the console, waits for +some regular expressions and enters some answers + +=item + +temporarily override assorted C configuration variables + +=item + +specify dependencies the original maintainer forgot + +=item + +disable the installation of an object altogether + +=back + +See the YAML and Data::Dumper files that come with the C +distribution in the C directory for examples. + +=head2 Filenames + +The YAML files themselves must have the C<.yml> extension; all other +files are ignored (for two exceptions see I below). The containing directory can be specified in +C in the C config variable. Try C in the CPAN shell to set and activate the distroprefs +system. + +Every YAML file may contain arbitrary documents according to the YAML +specification, and every document is treated as an entity that +can specify the treatment of a single distribution. + +Filenames can be picked arbitrarily; C always reads +all files (in alphabetical order) and takes the key C (see +below in I) as a hashref containing match criteria +that determine if the current distribution matches the YAML document +or not. + +=head2 Fallback Data::Dumper and Storable + +If neither your configured C nor YAML.pm is installed, +CPAN.pm falls back to using Data::Dumper and Storable and looks for +files with the extensions C<.dd> or C<.st> in the C +directory. These files are expected to contain one or more hashrefs. +For Data::Dumper generated files, this is expected to be done with by +defining C<$VAR1>, C<$VAR2>, etc. The YAML shell would produce these +with the command + + ysh < somefile.yml > somefile.dd + +For Storable files the rule is that they must be constructed such that +C returns an array reference and the array +elements represent one distropref object each. The conversion from +YAML would look like so: + + perl -MYAML=LoadFile -MStorable=nstore -e ' + @y=LoadFile(shift); + nstore(\@y, shift)' somefile.yml somefile.st + +In bootstrapping situations it is usually sufficient to translate only +a few YAML files to Data::Dumper for crucial modules like +C, C and C. If you prefer Storable +over Data::Dumper, remember to pull out a Storable version that writes +an older format than all the other Storable versions that will need to +read them. + +=head2 Blueprint + +The following example contains all supported keywords and structures +with the exception of C which can be used instead of +C. + + --- + comment: "Demo" + match: + module: "Dancing::Queen" + distribution: "^CHACHACHA/Dancing-" + not_distribution: "\.zip$" + perl: "/usr/local/cariba-perl/bin/perl" + perlconfig: + archname: "freebsd" + not_cc: "gcc" + env: + DANCING_FLOOR: "Shubiduh" + disabled: 1 + cpanconfig: + make: gmake + pl: + args: + - "--somearg=specialcase" + + env: {} + + expect: + - "Which is your favorite fruit" + - "apple\n" + + make: + args: + - all + - extra-all + + env: {} + + expect: [] + + commandline: "echo SKIPPING make" + + test: + args: [] + + env: {} + + expect: [] + + install: + args: [] + + env: + WANT_TO_INSTALL: YES + + expect: + - "Do you really want to install" + - "y\n" + + patches: + - "ABCDE/Fedcba-3.14-ABCDE-01.patch" + + depends: + configure_requires: + LWP: 5.8 + build_requires: + Test::Exception: 0.25 + requires: + Spiffy: 0.30 + + +=head2 Language Specs + +Every YAML document represents a single hash reference.

With C, the timeout denotes the +timeout per question; with C it denotes the +timeout per byte received from the stream or questions. + +C is a reference to an array that contains alternating questions +and answers.

You have been warned:-) + +=head1 PROGRAMMER'S INTERFACE + +If you do not enter the shell, shell commands are +available both as methods (Cinstall(...)>) and as +functions in the calling package (C). Before calling low-level +commands, it makes sense to initialize components of CPAN you need, e.g.: + + CPAN::HandleConfig->load; + CPAN::Shell::setup_output; + CPAN::Index->reload; + +High-level commands do such initializations automatically. + +There's currently only one class that has a stable interface - +CPAN::Shell. All commands that are available in the CPAN shell are +methods of the class CPAN::Shell. The arguments on the commandline are +passed as arguments to the method. + +So if you take for example the shell command + + notest install A B C + +the actually executed command is + + CPAN::Shell->notest("install","A","B","C"); + +Each of the commands that produce listings of modules (C, +C, C) also return a list of the IDs of all modules +within the list. + +=over 2 + +=item expand($type,@things) + +The IDs of all objects available within a program are strings that can +be expanded to the corresponding real objects with the +Cexpand("Module",@things)> method. Expand returns a +list of CPAN::Module objects according to the C<@things> arguments +given. In scalar context, it returns only the first element of the +list. + +=item expandany(@things) + +Like expand, but returns objects of the appropriate type, i.e. +CPAN::Bundle objects for bundles, CPAN::Module objects for modules, and +CPAN::Distribution objects for distributions. Note: it does not expand +to CPAN::Author objects. + +=item Programming Examples + +This enables the programmer to do operations that combine +functionalities that are available in the shell. + + # install everything that is outdated on my disk: + perl -MCPAN -e 'CPAN::Shell->install(CPAN::Shell->r)' + + # install my favorite programs if necessary: + for $mod (qw(Net::FTP Digest::SHA Data::Dumper)) { + CPAN::Shell->install($mod); + } + + # list all modules on my disk that have no VERSION number + for $mod (CPAN::Shell->expand("Module","/./")) { + next unless $mod->inst_file; + # MakeMaker convention for undefined $VERSION: + next unless $mod->inst_version eq "undef"; + print "No VERSION in ", $mod->id, "\n"; + } + + # find out which distribution on CPAN contains a module: + print CPAN::Shell->expand("Module","Apache::Constants")->cpan_file + +Or if you want to schedule a I job to watch CPAN, you could list +all modules that need updating. First a quick and dirty way: + + perl -e 'use CPAN; CPAN::Shell->r;' + +If you don't want any output should all modules be +up to date, parse the output of above command for the regular +expression C and decide to mail the output +only if it doesn't match. + +If you prefer to do it more in a programmerish style in one single +process, something like this may better suit you: + + # list all modules on my disk that have newer versions on CPAN + for $mod (CPAN::Shell->expand("Module","/./")) { + next unless $mod->inst_file; + next if $mod->uptodate; + printf "Module %s is installed as %s, could be updated to %s from CPAN\n", + $mod->id, $mod->inst_version, $mod->cpan_version; + } + +If that gives too much output every day, you may want to +watch only for three modules. You can write + + for $mod (CPAN::Shell->expand("Module","/Apache|LWP|CGI/")) { + +as the first line instead. Or you can combine some of the above +tricks: + + # watch only for a new mod_perl module + $mod = CPAN::Shell->expand("Module","mod_perl"); + exit if $mod->uptodate; + # new mod_perl arrived, let me know all update recommendations + CPAN::Shell->r; + +=back + +=head2 Methods in the other Classes + +=over 4 + +=item CPAN::Author::as_glimpse() + +Returns a one-line description of the author + +=item CPAN::Author::as_string() + +Returns a multi-line description of the author + +=item CPAN::Author::email() + +Returns the author's email address + +=item CPAN::Author::fullname() + +Returns the author's name + +=item CPAN::Author::name() + +An alias for fullname + +=item CPAN::Bundle::as_glimpse() + +Returns a one-line description of the bundle + +=item CPAN::Bundle::as_string() + +Returns a multi-line description of the bundle + +=item CPAN::Bundle::clean() + +Recursively runs the C method on all items contained in the bundle. + +=item CPAN::Bundle::contains() + +Returns a list of objects' IDs contained in a bundle.

It is a simple FIFO mechanism that +deletes complete directories below C as soon as the size of +all directories there gets bigger than $CPAN::Config->{build_cache} +(in MB). The contents of this cache may be used for later +re-installations that you intend to do manually, but will never be +trusted by CPAN itself. This is due to the fact that the user might +use these directories for building modules on different architectures. + +There is another directory ($CPAN::Config->{keep_source_where}) where +the original distribution files are kept. This directory is not +covered by the cache manager and must be controlled by the user. If +you choose to have the same directory as build_dir and as +keep_source_where directory, then your sources will be deleted with +the same fifo mechanism. + +=head2 Bundles + +A bundle is just a perl module in the namespace Bundle:: that does not +define any functions or methods. It usually only contains documentation. + +It starts like a perl module with a package declaration and a $VERSION +variable. After that the pod section looks like any other pod with the +only difference being that I exists starting with +(verbatim): + + =head1 CONTENTS + +In this pod section each line obeys the format + + Module_Name [Version_String] [- optional text] + +The only required part is the first field, the name of a module +(e.g. Foo::Bar, i.e. I the name of the distribution file). The rest +of the line is optional. The comment part is delimited by a dash just +as in the man page header. + +The distribution of a bundle should follow the same convention as +other distributions. + +Bundles are treated specially in the CPAN package. If you say 'install +Bundle::Tkkit' (assuming such a bundle exists), CPAN will install all +the modules in the CONTENTS section of the pod. You can install your +own Bundles locally by placing a conformant Bundle file somewhere into +your @INC path. The autobundle() command which is available in the +shell interface does that for you by including all currently installed +modules in a snapshot bundle file. + +=head1 PREREQUISITES + +The CPAN program is trying to depend on as little as possible so the +user can use it in hostile environment. It works better the more goodies +the environment provides. For example if you try in the CPAN shell + + install Bundle::CPAN + +or + + install Bundle::CPANxxl + +you will find the shell more convenient than the bare shell before. + +If you have a local mirror of CPAN and can access all files with +"file:" URLs, then you only need a perl later than perl5.003 to run +this module. Otherwise Net::FTP is strongly recommended. LWP may be +required for non-UNIX systems, or if your nearest CPAN site is +associated with a URL that is not C. + +If you have neither Net::FTP nor LWP, there is a fallback mechanism +implemented for an external ftp command or for an external lynx +command. + +=head1 UTILITIES + +=head2 Finding packages and VERSION + +This module presumes that all packages on CPAN + +=over 2 + +=item * + +declare their $VERSION variable in an easy to parse manner. This +prerequisite can hardly be relaxed because it consumes far too much +memory to load all packages into the running program just to determine +the $VERSION variable. Currently all programs that are dealing with +version use something like this + + perl -MExtUtils::MakeMaker -le \ + 'print MM->parse_version(shift)' filename + +If you are author of a package and wonder if your $VERSION can be +parsed, please try the above method. + +=item * + +come as compressed or gzipped tarfiles or as zip files and contain a +C or C (well, we try to handle a bit more, but +with little enthusiasm). + +=back + +=head2 Debugging + +Debugging this module is more than a bit complex due to interference from +the software producing the indices on CPAN, the mirroring process on CPAN, +packaging, configuration, synchronicity, and even (gasp!) due to bugs +within the CPAN.pm module itself. + +For debugging the code of CPAN.pm itself in interactive mode, some +debugging aid can be turned on for most packages within +CPAN.pm with one of + +=over 2 + +=item o debug package... + +sets debug mode for packages. + +=item o debug -package... + +unsets debug mode for packages. + +=item o debug all + +turns debugging on for all packages. + +=item o debug number + +=back + +which sets the debugging packages directly. Note that C +turns debugging off. + +What seems a successful strategy is the combination of C and the debugging switches. Add a new debug statement while +running in the shell and then issue a C and see the new +debugging messages immediately without losing the current context. + +C without an argument lists the valid package names and the +current set of packages in debugging mode. C has built-in +completion support. + +For debugging of CPAN data there is the C command which takes +the same arguments as make/test/install and outputs each object's +Data::Dumper dump. If an argument looks like a perl variable and +contains one of C<$>, C<@> or C<%>, it is eval()ed and fed to +Data::Dumper directly. + +=head2 Floppy, Zip, Offline Mode + +CPAN.pm works nicely without network access, too. If you maintain machines +that are not networked at all, you should consider working with C +URLs. You'll have to collect your modules somewhere first. So +you might use CPAN.pm to put together all you need on a networked +machine. Then copy the $CPAN::Config->{keep_source_where} (but not +$CPAN::Config->{build_dir}) directory on a floppy. This floppy is kind +of a personal CPAN. CPAN.pm on the non-networked machines works nicely +with this floppy. See also below the paragraph about CD-ROM support. + +=head2 Basic Utilities for Programmers + +=over 2 + +=item has_inst($module) + +Returns true if the module is installed. Used to load all modules into +the running CPAN.pm that are considered optional. The config variable +C intercepts the C call such +that an optional module is not loaded despite being available. For +example, the following command will prevent C from being +loaded: + + cpan> o conf dontload_list push YAML + +See the source for details. + +=item use_inst($module) + +Similary to L tries to load optional library but also dies if +library is not available + +=item has_usable($module) + +Returns true if the module is installed and in a usable state. Only +useful for a handful of modules that are used internally. See the +source for details. + +=item instance($module) + +The constructor for all the singletons used to represent modules, +distributions, authors, and bundles. If the object already exists, this +method returns the object; otherwise, it calls the constructor. + +=item frontend() + +=item frontend($new_frontend) + +Getter/setter for frontend object. Method just allows to subclass CPAN.pm. + +=back + +=head1 SECURITY + +There's no strong security layer in CPAN.pm. CPAN.pm helps you to +install foreign, unmasked, unsigned code on your machine. We compare +to a checksum that comes from the net just as the distribution file +itself. But we try to make it easy to add security on demand: + +=head2 Cryptographically signed modules + +Since release 1.77, CPAN.pm has been able to verify cryptographically +signed module distributions using Module::Signature. The CPAN modules +can be signed by their authors, thus giving more security. The simple +unsigned MD5 checksums that were used before by CPAN protect mainly +against accidental file corruption. + +You will need to have Module::Signature installed, which in turn +requires that you have at least one of Crypt::OpenPGP module or the +command-line F tool installed. + +You will also need to be able to connect over the Internet to the public +key servers, like pgp.mit.edu, and their port 11731 (the HKP protocol). + +The configuration parameter check_sigs is there to turn signature +checking on or off. + +=head1 EXPORT + +Most functions in package CPAN are exported by default. The reason +for this is that the primary use is intended for the cpan shell or for +one-liners. + +=head1 ENVIRONMENT + +When the CPAN shell enters a subshell via the look command, it sets +the environment CPAN_SHELL_LEVEL to 1, or increments that variable if it is +already set. + +When CPAN runs, it sets the environment variable PERL5_CPAN_IS_RUNNING +to the ID of the running process. It also sets +PERL5_CPANPLUS_IS_RUNNING to prevent runaway processes which could +happen with older versions of Module::Install. + +When running C, the environment variable +C is set to the full path of the +C that is being executed. This prevents runaway processes +with newer versions of Module::Install. + +When the config variable ftp_passive is set, all downloads will be run +with the environment variable FTP_PASSIVE set to this value. This is +in general a good idea as it influences both Net::FTP and LWP based +connections. The same effect can be achieved by starting the cpan +shell with this environment variable set. For Net::FTP alone, one can +also always set passive mode by running libnetcfg. + +=head1 POPULATE AN INSTALLATION WITH LOTS OF MODULES + +Populating a freshly installed perl with one's favorite modules is pretty +easy if you maintain a private bundle definition file. To get a useful +blueprint of a bundle definition file, the command autobundle can be used +on the CPAN shell command line. This command writes a bundle definition +file for all modules installed for the current perl +interpreter. It's recommended to run this command once only, and from then +on maintain the file manually under a private name, say +Bundle/my_bundle.pm. With a clever bundle file you can then simply say + + cpan> install Bundle::my_bundle + +then answer a few questions and go out for coffee (possibly +even in a different city). + +Maintaining a bundle definition file means keeping track of two +things: dependencies and interactivity. CPAN.pm sometimes fails on +calculating dependencies because not all modules define all MakeMaker +attributes correctly, so a bundle definition file should specify +prerequisites as early as possible. On the other hand, it's +annoying that so many distributions need some interactive configuring. So +what you can try to accomplish in your private bundle file is to have the +packages that need to be configured early in the file and the gentle +ones later, so you can go out for coffee after a few minutes and leave CPAN.pm +to churn away unattended. + +=head1 WORKING WITH CPAN.pm BEHIND FIREWALLS + +Thanks to Graham Barr for contributing the following paragraphs about +the interaction between perl, and various firewall configurations. For +further information on firewalls, it is recommended to consult the +documentation that comes with the I program. If you are unable to +go through the firewall with a simple Perl setup, it is likely +that you can configure I so that it works through your firewall. + +=head2 Three basic types of firewalls + +Firewalls can be categorized into three basic types. + +=over 4 + +=item http firewall + +This is when the firewall machine runs a web server, and to access the +outside world, you must do so via that web server. If you set environment +variables like http_proxy or ftp_proxy to values beginning with http://, +or in your web browser you've proxy information set, then you know +you are running behind an http firewall. + +To access servers outside these types of firewalls with perl (even for +ftp), you need LWP or HTTP::Tiny. + +=item ftp firewall + +This where the firewall machine runs an ftp server. This kind of +firewall will only let you access ftp servers outside the firewall. +This is usually done by connecting to the firewall with ftp, then +entering a username like "user@outside.host.com". + +To access servers outside these type of firewalls with perl, you +need Net::FTP. + +=item One-way visibility + +One-way visibility means these firewalls try to make themselves +invisible to users inside the firewall. An FTP data connection is +normally created by sending your IP address to the remote server and then +listening for the return connection. But the remote server will not be able to +connect to you because of the firewall. For these types of firewall, +FTP connections need to be done in a passive mode. + +There are two that I can think off. + +=over 4 + +=item SOCKS + +If you are using a SOCKS firewall, you will need to compile perl and link +it with the SOCKS library. This is what is normally called a 'socksified' +perl. With this executable you will be able to connect to servers outside +the firewall as if it were not there. + +=item IP Masquerade + +This is when the firewall implemented in the kernel (via NAT, or networking +address translation), it allows you to hide a complete network behind one +IP address. With this firewall no special compiling is needed as you can +access hosts directly. + +For accessing ftp servers behind such firewalls you usually need to +set the environment variable C or the config variable +ftp_passive to a true value. + +=back + +=back + +=head2 Configuring lynx or ncftp for going through a firewall + +If you can go through your firewall with e.g. lynx, presumably with a +command such as + + /usr/local/bin/lynx -pscott:tiger + +then you would configure CPAN.pm with the command + + o conf lynx "/usr/local/bin/lynx -pscott:tiger" + +That's all. Similarly for ncftp or ftp, you would configure something +like + + o conf ncftp "/usr/bin/ncftp -f /home/scott/ncftplogin.cfg" + +Your mileage may vary... + +=head1 FAQ + +=over 4 + +=item 1) + +I installed a new version of module X but CPAN keeps saying, +I have the old version installed + +Probably you B have the old version installed. This can +happen if a module installs itself into a different directory in the +@INC path than it was previously installed. This is not really a +CPAN.pm problem, you would have the same problem when installing the +module manually. The easiest way to prevent this behaviour is to add +the argument C to the C call, and that is why +many people add this argument permanently by configuring + + o conf make_install_arg UNINST=1 + +=item 2) + +So why is UNINST=1 not the default? + +Because there are people who have their precise expectations about who +may install where in the @INC path and who uses which @INC array. In +fine tuned environments C can cause damage. + +=item 3) + +I want to clean up my mess, and install a new perl along with +all modules I have. How do I go about it? + +Run the autobundle command for your old perl and optionally rename the +resulting bundle file (e.g. Bundle/mybundle.pm), install the new perl +with the Configure option prefix, e.g. + + ./Configure -Dprefix=/usr/local/perl-5.6.78.9 + +Install the bundle file you produced in the first step with something like + + cpan> install Bundle::mybundle + +and you're done. + +=item 4) + +When I install bundles or multiple modules with one command +there is too much output to keep track of. + +You may want to configure something like + + o conf make_arg "| tee -ai /root/.cpan/logs/make.out" + o conf make_install_arg "| tee -ai /root/.cpan/logs/make_install.out" + +so that STDOUT is captured in a file for later inspection. + + +=item 5) + +I am not root, how can I install a module in a personal directory? + +As of CPAN 1.9463, if you do not have permission to write the default perl +library directories, CPAN's configuration process will ask you whether +you want to bootstrap , which makes keeping a personal +perl library directory easy. + +Another thing you should bear in mind is that the UNINST parameter can +be dangerous when you are installing into a private area because you +might accidentally remove modules that other people depend on that are +not using the private area. + +=item 6) + +How to get a package, unwrap it, and make a change before building it? + +Have a look at the C (!) command. + +=item 7) + +I installed a Bundle and had a couple of fails. When I +retried, everything resolved nicely. Can this be fixed to work +on first try? + +The reason for this is that CPAN does not know the dependencies of all +modules when it starts out. To decide about the additional items to +install, it just uses data found in the META.yml file or the generated +Makefile. An undetected missing piece breaks the process. But it may +well be that your Bundle installs some prerequisite later than some +depending item and thus your second try is able to resolve everything. +Please note, CPAN.pm does not know the dependency tree in advance and +cannot sort the queue of things to install in a topologically correct +order. It resolves perfectly well B all modules declare the +prerequisites correctly with the PREREQ_PM attribute to MakeMaker or +the C stanza of Module::Build. For bundles which fail and +you need to install often, it is recommended to sort the Bundle +definition file manually. + +=item 8) + +In our intranet, we have many modules for internal use. How +can I integrate these modules with CPAN.pm but without uploading +the modules to CPAN? + +Have a look at the CPAN::Site module. + +=item 9) + +When I run CPAN's shell, I get an error message about things in my +C (or C<~/.inputrc>) file. + +These are readline issues and can only be fixed by studying readline +configuration on your architecture and adjusting the referenced file +accordingly. Please make a backup of the C or C<~/.inputrc> +and edit them. Quite often harmless changes like uppercasing or +lowercasing some arguments solves the problem. + +=item 10) + +Some authors have strange characters in their names. + +Internally CPAN.pm uses the UTF-8 charset. If your terminal is +expecting ISO-8859-1 charset, a converter can be activated by setting +term_is_latin to a true value in your config file. One way of doing so +would be + + cpan> o conf term_is_latin 1 + +If other charset support is needed, please file a bug report against +CPAN.pm at rt.cpan.org and describe your needs. Maybe we can extend +the support or maybe UTF-8 terminals become widely available. + +Note: this config variable is deprecated and will be removed in a +future version of CPAN.pm. It will be replaced with the conventions +around the family of $LANG and $LC_* environment variables. + +=item 11) + +When an install fails for some reason and then I correct the error +condition and retry, CPAN.pm refuses to install the module, saying +C. + +You could use the force pragma like so + + force install Foo::Bar + +Or, to avoid a force install (which would install even if the tests +fail), you can force only the test and then install: + + force test Foo::Bar + install Foo::Bar + +Or you can use + + look Foo::Bar + +and then C directly in the subshell. + +=item 12) + +How do I install a "DEVELOPER RELEASE" of a module? + +By default, CPAN will install the latest non-developer release of a +module. If you want to install a dev release, you have to specify the +partial path starting with the author id to the tarball you wish to +install, like so: + + cpan> install KWILLIAMS/Module-Build-0.27_07.tar.gz + +Note that you can use the C command to get this path listed. + +=item 13) + +How do I install a module and all its dependencies from the commandline, +without being prompted for anything, despite my CPAN configuration +(or lack thereof)? + +CPAN uses ExtUtils::MakeMaker's prompt() function to ask its questions, so +if you set the PERL_MM_USE_DEFAULT environment variable, you shouldn't be +asked any questions at all (assuming the modules you are installing are +nice about obeying that variable as well): + + % PERL_MM_USE_DEFAULT=1 perl -MCPAN -e 'install My::Module' + +=item 14) + +How do I create a Module::Build based Build.PL derived from an +ExtUtils::MakeMaker focused Makefile.PL? + +http://search.cpan.org/dist/Module-Build-Convert/ + +=item 15) + +I'm frequently irritated with the CPAN shell's inability to help me +select a good mirror. + +CPAN can now help you select a "good" mirror, based on which ones have the +lowest 'ping' round-trip times. From the shell, use the command 'o conf init +urllist' and allow CPAN to automatically select mirrors for you. + +Beyond that help, the urllist config parameter is yours. You can add and remove +sites at will. You should find out which sites have the best up-to-dateness, +bandwidth, reliability, etc. and are topologically close to you. Some people +prefer fast downloads, others up-to-dateness, others reliability. You decide +which to try in which order. + +Henk P. Penning maintains a site that collects data about CPAN sites: + + http://mirrors.cpan.org/ + +Also, feel free to play with experimental features. Run + + o conf init randomize_urllist ftpstats_period ftpstats_size + +and choose your favorite parameters. After a few downloads running the +C command will probably assist you in choosing the best mirror +sites. + +=item 16) + +Why do I get asked the same questions every time I start the shell? + +You can make your configuration changes permanent by calling the +command C. Alternatively set the C +variable to true by running C and answering +the following question with yes. + +=item 17) + +Older versions of CPAN.pm had the original root directory of all +tarballs in the build directory. Now there are always random +characters appended to these directory names. Why was this done? + +The random characters are provided by File::Temp and ensure that each +module's individual build directory is unique. This makes running +CPAN.pm in concurrent processes simultaneously safe. + +=item 18) + +Speaking of the build directory. Do I have to clean it up myself? + +You have the choice to set the config variable C to +C. Then you must clean it up yourself. The other possible +values, C and C clean up the build directory when you +start (or more precisely, after the first extraction into the build +directory) or exit the CPAN shell, respectively. If you never start up +the CPAN shell, you probably also have to clean up the build directory +yourself. + +=item 19) + +How can I switch to sudo instead of local::lib? + +The following 5 environment veriables need to be reset to the previous +values: PATH, PERL5LIB, PERL_LOCAL_LIB_ROOT, PERL_MB_OPT, PERL_MM_OPT; +and these two CPAN.pm config variables must be reconfigured: +make_install_make_command and mbuild_install_build_command. The five +env variables have probably been overwritten in your $HOME/.bashrc or +some equivalent. You either find them there and delete their traces +and logout/login or you override them temporarily, depending on your +exact desire. The two cpanpm config variables can be set with: + + o conf init /install_.*_command/ + +probably followed by + + o conf commit + +=item 20) + +How do recommends_policy and suggests_policy work, exactly? + +The terms C and C have been standardized in +https://metacpan.org/pod/CPAN::Meta::Spec + +In CPAN.pm, if you set C to a true value, that +means: if you then install a distribution C that I a +module C, both C and C will be tested and potentially +installed. + +Similarly, if you set C to a true value, it means: if +you install a distribution C that I a module C, +both C and C will be tested and potentially installed. + +In either case, when C passes its tests and C does not pass +its tests, C will be installed nontheless. But if C does not +pass its tests, neither will be installed. + +This also works recursively for all recommends and suggests of the +module C. + +This has also been illustrated by a cpan tester, who wrote: + +I just tested Starlink-AST-3.03 which recommends Tk::Zinc; +Tk-Zinc-3.306 fails with +http://www.cpantesters.org/cpan/report/a2de7c38-810d-11ee-9ad4-e2167316189a +; nonetheless Starlink-AST-3.03 succeeds with +http://www.cpantesters.org/cpan/report/9352e754-810d-11ee-90e9-46117316189a + +=back + +=head1 COMPATIBILITY + +=head2 OLD PERL VERSIONS + +CPAN.pm is regularly tested to run under 5.005 and assorted +newer versions. It is getting more and more difficult to get the +minimal prerequisites working on older perls. It is close to +impossible to get the whole Bundle::CPAN working there. If you're in +the position to have only these old versions, be advised that CPAN is +designed to work fine without the Bundle::CPAN installed. + +To get things going, note that GBARR/Scalar-List-Utils-1.18.tar.gz is +compatible with ancient perls and that File::Temp is listed as a +prerequisite but CPAN has reasonable workarounds if it is missing. + +=head2 CPANPLUS + +This module and its competitor, the CPANPLUS module, are both much +cooler than the other. CPAN.pm is older. CPANPLUS was designed to be +more modular, but it was never intended to be compatible with CPAN.pm. + +=head2 CPANMINUS + +In the year 2010 App::cpanminus was launched as a new approach to a +cpan shell with a considerably smaller footprint.

+ +=over 2 + +=item allow_installing_module_downgrades + +The CPAN shell can watch the C<blib/> directories that are built up +before running C<make test> to determine whether the current +distribution will end up with modules being overwritten with decreasing module version numbers. It +can then let the build of this distro fail when it discovers a +downgrade. + +Do you want to allow installing distros with decreasing module +versions compared to what you have installed (yes, no, ask/yes, +ask/no)? + +=item allow_installing_outdated_dists + +The CPAN shell can watch the C<blib/> directories that are built up +before running C<make test> to determine whether the current +distribution contains modules that are indexed with a distro with a +higher distro-version number than the current one. It can +then let the build of this distro fail when it would not represent the +most up-to-date version of the distro. + +Note: choosing anything but 'yes' for this option will need +CPAN::DistnameInfo being installed for taking effect. + +Do you want to allow installing distros that are not indexed as the +highest distro-version for all contained modules (yes, no, ask/yes, +ask/no)? + +=item auto_commit + +Normally CPAN.pm keeps config variables in memory and changes need to +be saved in a separate 'o conf commit' command to make them permanent +between sessions. If you set the 'auto_commit' option to true, changes +to a config variable are always automatically committed to disk. + +Always commit changes to config variables to disk? + +=item build_cache + +CPAN.pm can limit the size of the disk area for keeping the build +directories with all the intermediate files. + +Cache size for build directory (in MB)? + +=item build_dir + +Directory where the build process takes place? + +=item build_dir_reuse + +Until version 1.88 CPAN.pm never trusted the contents of the build_dir +directory between sessions. Since 1.88_58 CPAN.pm has a YAML-based +mechanism that makes it possible to share the contents of the +build_dir/ directory between different sessions with the same version +of perl. People who prefer to test things several days before +installing will like this feature because it saves a lot of time. + +If you say yes to the following question, CPAN will try to store +enough information about the build process so that it can pick up in +future sessions at the same state of affairs as it left a previous +session. + +Store and re-use state information about distributions between +CPAN.pm sessions? + +=item build_requires_install_policy + +When a module declares another one as a 'build_requires' prerequisite +this means that the other module is only needed for building or +testing the module but need not be installed permanently. In this case +you may wish to install that other module nonetheless or just keep it +in the 'build_dir' directory to have it available only temporarily. +Installing saves time on future installations but makes the perl +installation bigger. + +You can choose if you want to always install (yes), never install (no) +or be always asked. In the latter case you can set the default answer +for the question to yes (ask/yes) or no (ask/no). + +Policy on installing 'build_requires' modules (yes, no, ask/yes, +ask/no)? + +=item cache_metadata + +To considerably speed up the initial CPAN shell startup, it is +possible to use Storable to create a cache of metadata. If Storable is +not available, the normal index mechanism will be used. + +Note: this mechanism is not used when use_sqlite is on and SQLite is +running. + +Cache metadata (yes/no)? + +=item check_sigs + +CPAN packages can be digitally signed by authors and thus verified +with the security provided by strong cryptography. The exact mechanism +is defined in the Module::Signature module. While this is generally +considered a good thing, it is not always convenient to the end user +to install modules that are signed incorrectly or where the key of the +author is not available or where some prerequisite for +Module::Signature has a bug and so on. + +With the check_sigs parameter you can turn signature checking on and +off. The default is off for now because the whole tool chain for the +functionality is not yet considered mature by some. The author of +CPAN.pm would recommend setting it to true most of the time and +turning it off only if it turns out to be annoying. + +Note that if you do not have Module::Signature installed, no signature +checks will be performed at all. + +Always try to check and verify signatures if a SIGNATURE file is in +the package and Module::Signature is installed (yes/no)? + +=item cleanup_after_install + +Users who install modules and do not intend to look back, can free +occupied disk space quickly by letting CPAN.pm cleanup each build +directory immediately after a successful install. + +Remove build directory after a successful install? (yes/no)? + +=item colorize_output + +When you have Term::ANSIColor installed, you can turn on colorized +output to have some visual differences between normal CPAN.pm output, +warnings, debugging output, and the output of the modules being +installed. Set your favorite colors after some experimenting with the +Term::ANSIColor module. + +Please note that on Windows platforms colorized output also requires +the Win32::Console::ANSI module. + +Do you want to turn on colored output? + +=item colorize_print + +Color for normal output? + +=item colorize_warn + +Color for warnings? + +=item colorize_debug + +Color for debugging messages? + +=item commandnumber_in_prompt + +The prompt of the cpan shell can contain the current command number +for easier tracking of the session or be a plain string. + +Do you want the command number in the prompt (yes/no)? + +=item connect_to_internet_ok + +If you have never defined your own C<urllist> in your configuration +then C<CPAN.pm> will be hesitant to use the built in default sites for +downloading. It will ask you once per session if a connection to the +internet is OK and only if you say yes, it will try to connect. But to +avoid this question, you can choose your favorite download sites once +and get away with it. Or, if you have no favorite download sites +answer yes to the following question. + +If no urllist has been chosen yet, would you prefer CPAN.pm to connect +to the built-in default sites without asking? (yes/no)? + +=item ftp_passive + +Shall we always set the FTP_PASSIVE environment variable when dealing +with ftp download (yes/no)? + +=item ftpstats_period + +Statistics about downloads are truncated by size and period +simultaneously. + +How many days shall we keep statistics about downloads? + +=item ftpstats_size + +Statistics about downloads are truncated by size and period +simultaneously. Setting this to zero or negative disables download +statistics. + +How many items shall we keep in the statistics about downloads? + +=item getcwd + +CPAN.pm changes the current working directory often and needs to +determine its own current working directory. Per default it uses +Cwd::cwd but if this doesn't work on your system for some reason, +alternatives can be configured according to the following table: + + cwd Cwd::cwd + getcwd Cwd::getcwd + fastcwd Cwd::fastcwd + getdcwd Cwd::getdcwd + backtickcwd external command cwd + +Preferred method for determining the current working directory? + +=item halt_on_failure + +Normally, CPAN.pm continues processing the full list of targets and +dependencies, even if one of them fails. However, you can specify +that CPAN should halt after the first failure. (Note that optional +recommended or suggested modules that fail will not cause a halt.) + +Do you want to halt on failure (yes/no)? + +=item histfile + +If you have one of the readline packages (Term::ReadLine::Perl, +Term::ReadLine::Gnu, possibly others) installed, the interactive CPAN +shell will have history support. The next two questions deal with the +filename of the history file and with its size. If you do not want to +set this variable, please hit SPACE ENTER to the following question. + +File to save your history? + +=item histsize + +Number of lines to save? + +=item inactivity_timeout + +Sometimes you may wish to leave the processes run by CPAN alone +without caring about them. Because the Makefile.PL or the Build.PL +sometimes contains question you're expected to answer, you can set a +timer that will kill a 'perl Makefile.PL' process after the specified +time in seconds. + +If you set this value to 0, these processes will wait forever. This is +the default and recommended setting. + +Timeout for inactivity during {Makefile,Build}.PL? + +=item index_expire + +The CPAN indexes are usually rebuilt once or twice per hour, but the +typical CPAN mirror mirrors only once or twice per day. Depending on +the quality of your mirror and your desire to be on the bleeding edge, +you may want to set the following value to more or less than one day +(which is the default). It determines after how many days CPAN.pm +downloads new indexes. + +Let the index expire after how many days? + +=item inhibit_startup_message + +When the CPAN shell is started it normally displays a greeting message +that contains the running version and the status of readline support. + +Do you want to turn this message off? + +=item keep_source_where + +Unless you are accessing the CPAN on your filesystem via a file: URL, +CPAN.pm needs to keep the source files it downloads somewhere. Please +supply a directory where the downloaded files are to be kept. + +Download target directory? + +=item load_module_verbosity + +When CPAN.pm loads a module it needs for some optional feature, it +usually reports about module name and version. Choose 'v' to get this +message, 'none' to suppress it. + +Verbosity level for loading modules (none or v)? + +=item makepl_arg + +Every Makefile.PL is run by perl in a separate process. Likewise we +run 'make' and 'make install' in separate processes. If you have +any parameters (e.g. PREFIX, UNINST or the like) you want to +pass to the calls, please specify them here. + +If you don't understand this question, just press ENTER. + +Typical frequently used settings: + + PREFIX=~/perl # non-root users (please see manual for more hints) + +Parameters for the 'perl Makefile.PL' command? + +=item make_arg + +Parameters for the 'make' command? Typical frequently used setting: + + -j3 # dual processor system (on GNU make) + +Your choice: + +=item make_install_arg + +Parameters for the 'make install' command? +Typical frequently used setting: + + UNINST=1 # to always uninstall potentially conflicting files + # (but do NOT use with local::lib or INSTALL_BASE) + +Your choice: + +=item make_install_make_command + +Do you want to use a different make command for 'make install'? +Cautious people will probably prefer: + + su root -c make + or + sudo make + or + /path1/to/sudo -u admin_account /path2/to/make + +or some such. Your choice: + +=item mbuildpl_arg + +A Build.PL is run by perl in a separate process. Likewise we run +'./Build' and './Build install' in separate processes. If you have any +parameters you want to pass to the calls, please specify them here. + +Typical frequently used settings: + + --install_base /home/xxx # different installation directory + +Parameters for the 'perl Build.PL' command? + +=item mbuild_arg + +Parameters for the './Build' command? Setting might be: + + --extra_linker_flags -L/usr/foo/lib # non-standard library location + +Your choice: + +=item mbuild_install_arg + +Parameters for the './Build install' command? Typical frequently used +setting: + + --uninst 1 # uninstall conflicting files + # (but do NOT use with local::lib or INSTALL_BASE) + +Your choice: + +=item mbuild_install_build_command + +Do you want to use a different command for './Build install'? Sudo +users will probably prefer: + + su root -c ./Build + or + sudo ./Build + or + /path1/to/sudo -u admin_account ./Build + +or some such. Your choice: + +=item pager + +What is your favorite pager program? + +=item prefer_installer + +When you have Module::Build installed and a module comes with both a +Makefile.PL and a Build.PL, which shall have precedence? + +The main two standard installer modules are the old and well +established ExtUtils::MakeMaker (for short: EUMM) which uses the +Makefile.PL. And the next generation installer Module::Build (MB) +which works with the Build.PL (and often comes with a Makefile.PL +too). If a module comes only with one of the two we will use that one +but if both are supplied then a decision must be made between EUMM and +MB. See also http://rt.cpan.org/Ticket/Display.html?id=29235 for a +discussion about the right default. + +Or, as a third option you can choose RAND which will make a random +decision (something regular CPAN testers will enjoy). + +In case you can choose between running a Makefile.PL or a Build.PL, +which installer would you prefer (EUMM or MB or RAND)? + +=item prefs_dir + +CPAN.pm can store customized build environments based on regular +expressions for distribution names. These are YAML files where the +default options for CPAN.pm and the environment can be overridden and +dialog sequences can be stored that can later be executed by an +Expect.pm object. The CPAN.pm distribution comes with some prefab YAML +files that cover sample distributions that can be used as blueprints +to store your own prefs. Please check out the distroprefs/ directory of +the CPAN.pm distribution to get a quick start into the prefs system. + +Directory where to store default options/environment/dialogs for +building modules that need some customization? + +=item prerequisites_policy + +The CPAN module can detect when a module which you are trying to build +depends on prerequisites. If this happens, it can build the +prerequisites for you automatically ('follow'), ask you for +confirmation ('ask'), or just ignore them ('ignore'). Choosing +'follow' also sets PERL_AUTOINSTALL and PERL_EXTUTILS_AUTOINSTALL for +"--defaultdeps" if not already set. + +Please set your policy to one of the three values. + +Policy on building prerequisites (follow, ask or ignore)? + +=item pushy_https + +Boolean. Defaults to true. If this option is true, the cpan shell will +use https://cpan.org/ to download stuff from the CPAN. It will fall +back to http://cpan.org/ if it can't handle https for some reason +(missing modules, missing programs). Whenever it falls back to the +http protocol, it will issue a warning. + +If this option is true, the option C<urllist> will be ignored. +Consequently, if you want to work with local mirrors via your own +configured list of URLs, you will have to choose no below. + +Do you want to turn the pushy_https behaviour on? + +=item randomize_urllist + +CPAN.pm can introduce some randomness when using hosts for download +that are configured in the urllist parameter. Enter a numeric value +between 0 and 1 to indicate how often you want to let CPAN.pm try a +random host from the urllist. A value of one specifies to always use a +random host as the first try. A value of zero means no randomness at +all. Anything in between specifies how often, on average, a random +host should be tried first. + +Randomize parameter + +=item recommends_policy + +(Experimental feature!) Some CPAN modules recommend additional, optional dependencies. These should +generally be installed except in resource constrained environments. When this +policy is true, recommended modules will be included with required modules. + +Include recommended modules? + +=item scan_cache + +By default, each time the CPAN module is started, cache scanning is +performed to keep the cache size in sync ('atstart'). Alternatively, +scanning and cleanup can happen when CPAN exits ('atexit'). To prevent +any cache cleanup, answer 'never'. + +Perform cache scanning ('atstart', 'atexit' or 'never')? + +=item shell + +What is your favorite shell? + +=item show_unparsable_versions + +During the 'r' command CPAN.pm finds modules without version number. +When the command finishes, it prints a report about this. If you +want this report to be very verbose, say yes to the following +variable. + +Show all individual modules that have no $VERSION? + +=item show_upload_date + +The 'd' and the 'm' command normally only show you information they +have in their in-memory database and thus will never connect to the +internet. If you set the 'show_upload_date' variable to true, 'm' and +'d' will additionally show you the upload date of the module or +distribution. Per default this feature is off because it may require a +net connection to get at the upload date. + +Always try to show upload date with 'd' and 'm' command (yes/no)? + +=item show_zero_versions + +During the 'r' command CPAN.pm finds modules with a version number of +zero. When the command finishes, it prints a report about this. If you +want this report to be very verbose, say yes to the following +variable. + +Show all individual modules that have a $VERSION of zero? + +=item suggests_policy + +(Experimental feature!) Some CPAN modules suggest additional, optional dependencies. These 'suggest' +dependencies provide enhanced operation. When this policy is true, suggested +modules will be included with required modules. + +Include suggested modules? + +=item tar_verbosity + +When CPAN.pm uses the tar command, which switch for the verbosity +shall be used? Choose 'none' for quiet operation, 'v' for file +name listing, 'vv' for full listing. + +Tar command verbosity level (none or v or vv)? + +=item term_is_latin + +The next option deals with the charset (a.k.a. character set) your +terminal supports. In general, CPAN is English speaking territory, so +the charset does not matter much but some CPAN have names that are +outside the ASCII range. If your terminal supports UTF-8, you should +say no to the next question. If it expects ISO-8859-1 (also known as +LATIN1) then you should say yes. If it supports neither, your answer +does not matter because you will not be able to read the names of some +authors anyway. If you answer no, names will be output in UTF-8. + +Your terminal expects ISO-8859-1 (yes/no)? + +=item term_ornaments + +When using Term::ReadLine, you can turn ornaments on so that your +input stands out against the output from CPAN.pm. + +Do you want to turn ornaments on? + +=item test_report + +The goal of the CPAN Testers project (http://testers.cpan.org/) is to +test as many CPAN packages as possible on as many platforms as +possible. This provides valuable feedback to module authors and +potential users to identify bugs or platform compatibility issues and +improves the overall quality and value of CPAN. + +One way you can contribute is to send test results for each module +that you install. If you install the CPAN::Reporter module, you have +the option to automatically generate and deliver test reports to CPAN +Testers whenever you run tests on a CPAN package. + +See the CPAN::Reporter documentation for additional details and +configuration settings. If your firewall blocks outgoing traffic, +you may need to configure CPAN::Reporter before sending reports. + +Generate test reports if CPAN::Reporter is installed (yes/no)? + +=item perl5lib_verbosity + +When CPAN.pm extends @INC via PERL5LIB, it prints a list of +directories added (or a summary of how many directories are +added). Choose 'v' to get this message, 'none' to suppress it. + +Verbosity level for PERL5LIB changes (none or v)? + +=item prefer_external_tar + +Per default all untar operations are done with the perl module +Archive::Tar; by setting this variable to true the external tar +command is used if available; on Unix this is usually preferred +because they have a reliable and fast gnutar implementation. + +Use the external tar program instead of Archive::Tar? + +=item trust_test_report_history + +When a distribution has already been tested by CPAN::Reporter on +this machine, CPAN can skip the test phase and just rely on the +test report history instead. + +Note that this will not apply to distributions that failed tests +because of missing dependencies. Also, tests can be run +regardless of the history using "force". + +Do you want to rely on the test report history (yes/no)? + +=item urllist_ping_external + +When automatic selection of the nearest cpan mirrors is performed, +turn on the use of the external ping via Net::Ping::External. This is +recommended in the case the local network has a transparent proxy. + +Do you want to use the external ping command when autoselecting +mirrors? + +=item urllist_ping_verbose + +When automatic selection of the nearest cpan mirrors is performed, +this option can be used to turn on verbosity during the selection +process. + +Do you want to see verbosity turned on when autoselecting mirrors? + +=item use_prompt_default + +When this is true, CPAN will set PERL_MM_USE_DEFAULT to a true +value. This causes ExtUtils::MakeMaker (and compatible) prompts +to use default values instead of stopping to prompt you to answer +questions. It also sets NONINTERACTIVE_TESTING to a true value to +signal more generally that distributions should not try to +interact with you. + +Do you want to use prompt defaults (yes/no)? + +=item use_sqlite + +CPAN::SQLite is a layer between the index files that are downloaded +from the CPAN and CPAN.pm that speeds up metadata queries and reduces +memory consumption of CPAN.pm considerably. + +Use CPAN::SQLite if available? (yes/no)? + +=item version_timeout + +This timeout prevents CPAN from hanging when trying to parse a +pathologically coded $VERSION from a module. + +The default is 15 seconds. If you set this value to 0, no timeout +will occur, but this is not recommended. + +Timeout for parsing module versions? + +=item yaml_load_code + +Both YAML.pm and YAML::Syck are capable of deserialising code. As this +requires a string eval, which might be a security risk, you can use +this option to enable or disable the deserialisation of code via +CPAN::DeferredCode. (Note: This does not work under perl 5.6) + +Do you want to enable code deserialisation (yes/no)? + +=item yaml_module + +At the time of this writing (2009-03) there are three YAML +implementations working: YAML, YAML::Syck, and YAML::XS. The latter +two are faster but need a C compiler installed on your system. There +may be more alternative YAML conforming modules. When I tried two +other players, YAML::Tiny and YAML::Perl, they seemed not powerful +enough to work with CPAN.pm. This may have changed in the meantime. + +Which YAML implementation would you prefer? + +=back + +=head1 LICENSE + +This program is free software; you can redistribute it and/or +modify it under the same terms as Perl itself. + +=cut + +use vars qw( %prompts ); + +{ + + my @prompts = ( + +auto_config => qq{ +CPAN.pm requires configuration, but most of it can be done automatically. +If you answer 'no' below, you will enter an interactive dialog for each +configuration option instead. + +Would you like to configure as much as possible automatically?}, + +auto_pick => qq{ +Would you like me to automatically choose some CPAN mirror +sites for you?

If no meta-spec version is provided, version 1.0 will +be assumed. + +Optionally, you can provide a C<default_version> argument after C<$struct>: + + my $cmc = CPAN::Meta::Converter->new( $struct, default_version => "1.4" ); + +This is only needed when converting a metadata fragment that does not include a +C<meta-spec> field. + +=head2 convert + + my $new_struct = $cmc->convert( version => "2" ); + +Returns a new hash reference with the metadata converted to a different form. +C<convert> will die if any conversion/standardization still results in an +invalid structure. + +Valid parameters include: + +=over + +=item * + +C<version> -- Indicates the desired specification version (e.g. "1.0", "1.1" ... "1.4", "2"). +Defaults to the latest version of the CPAN Meta Spec. + +=back + +Conversion proceeds through each version in turn. For example, a version 1.2 +structure might be converted to 1.3 then 1.4 then finally to version 2. The +conversion process attempts to clean-up simple errors and standardize data. +For example, if C<author> is given as a scalar, it will converted to an array +reference containing the item. (Converting a structure to its own version will +also clean-up and standardize.) + +When data are cleaned and standardized, missing or invalid fields will be +replaced with sensible defaults when possible. This may be lossy or imprecise. +For example, some badly structured META.yml files on CPAN have prerequisite +modules listed as both keys and values: + + requires => { 'Foo::Bar' => 'Bam::Baz' } + +These would be split and each converted to a prerequisite with a minimum +version of zero. + +When some mandatory fields are missing or invalid, the conversion will attempt +to provide a sensible default or will fill them with a value of 'unknown'. For +example a missing or unrecognized C<license> field will result in a C<license> +field of 'unknown'.

In the context of this document it usually refers to a +collection of modules, scripts, and/or documents that are distributed +for other developers to use. + +=item module + +This refers to a reusable library of code typically contained in a +single file. Currently, we primarily talk of perl modules, but this +specification should be open enough to apply to other languages as +well (ex. python, ruby). + +=back + +=head1 VERSION SPECIFICATIONS + +Some fields require a version specification (ex. L</requires>, +L</recommends>, L</build_requires>, etc.). This section details the +version specifications that are currently supported. + +If a single version is listed, then that version is considered to be +the minimum version supported. + +If 0 is given as the version number, then any version is supported. + +Additionally, for more complicated requirements, the specification +supports a list of versions, each of which may be optionally preceded +by a relational operator. + +Supported operators include E<lt> (less than), E<lt>= (less than or +equal), E<gt> (greater than), E<gt>= (greater than or equal), == (equal), and != +(not equal). + +If a list is given then it is evaluated from left to right so that any +specifications in the list that conflict with a previous specification +are overridden by the later. + +Examples: + + >= 1.2, != 1.5, < 2.0 + +Any version from version 1.2 onward, except version 1.5, that also +precedes version 2.0. + +=head1 HEADER + +The first line of a F<META.yml> file should be a valid YAML document +header like C<"--- #YAML:1.0">. + +=head1 FIELDS + +The rest of the F<META.yml> file is one big YAML mapping whose keys +are described here. + +=head2 meta-spec + +Example: + + meta-spec: + version: 1.2 + url: http://module-build.sourceforge.net/META-spec-v1.2.html + +(Spec 1.1) [required] {URL} This field indicates the location of the +version of the META.yml specification used. + +=head2 name + +Example: + + name: Module-Build + +(Spec 1.0) [required] {string} The name of the distribution which is often +created by taking the "main module" in the distribution and changing +"::" to "-".

This information can be (and, in some +cases, is) used by distribution and automation mechanisms like PAUSE, +CPAN, and search.cpan.org to build indexes saying in which +distribution various packages can be found. + +When using tools like L<Module::Build> that can generate the +C<provides> mapping for your distribution automatically, make sure you +examine what it generates to make sure it makes sense - indexers will +usually trust the C<provides> field if it's present, rather than +scanning through the distribution files themselves to figure out +packages and versions.

In the context of this document it usually refers to a +collection of modules, scripts, and/or documents that are distributed +together for other developers to use. Examples of distributions are +C<Class-Container>, C<libwww-perl>, or C<DBI>. + +=item module + +This refers to a reusable library of code typically contained in a +single file. Currently, we primarily talk of perl modules, but this +specification should be open enough to apply to other languages as +well (ex. python, ruby).

It takes one mandatory named +argument, C<version>, declaring the version of the meta-spec that must be +used for the merge. It can optionally take an C<extra_mappings> argument +that allows one to add additional merging functions for specific elements. + +The C<extra_mappings> arguments takes a hash ref with the same type of +structure as described in L<CPAN::Meta::Spec>, except with its values as +one of the L<defined merge strategies|/"MERGE STRATEGIES"> or a code ref +to a merging function. + + my $merger = CPAN::Meta::Merge->new( + default_version => '2', + extra_mappings => { + 'optional_features' => \&custom_merge_function, + 'x_custom' => 'set_addition', + 'x_meta_meta' => { + name => 'identical', + tags => 'set_addition', + } + } + ); + +=head2 merge(@fragments) + +Merge all C<@fragments> together. It will accept both CPAN::Meta objects and +(possibly incomplete) hashrefs of metadata. + +=head1 MERGE STRATEGIES + +C<merge> uses various strategies to combine different elements of the CPAN::Meta objects.

For example, one might refer to C<File::Spec> instead of +F<File/Spec.pm> + +=item package + +This refers to a namespace declared with the Perl C<package> statement. +In Perl, packages often have a version number property given by the +C<$VERSION> variable in the namespace. + +=item consumer + +This refers to code that reads a metadata file, deserializes it into a +data structure in memory, or interprets a data structure of metadata +elements. + +=item producer + +This refers to code that constructs a metadata data structure, +serializes into a bytestream and/or writes it to disk. + +=item must, should, may, etc. + +These terms are interpreted as described in IETF RFC 2119. + +=back + +=head1 DATA TYPES + +Fields in the L</STRUCTURE> section describe data elements, each of +which has an associated data type as described herein. There are four +primitive types: Boolean, String, List and Map. Other types are +subtypes of primitives and define compound data structures or define +constraints on the values of a data element. + +=head2 Boolean + +A I<Boolean> is used to provide a true or false value. It B<must> be +represented as a defined value that is either "1" or "0" or stringifies +to those values. + +=head2 String + +A I<String> is data element containing a non-zero length sequence of +Unicode characters, such as an ordinary Perl scalar that is not a +reference. + +=head2 List + +A I<List> is an ordered collection of zero or more data elements. +Elements of a List may be of mixed types. + +Producers B<must> represent List elements using a data structure which +unambiguously indicates that multiple values are possible, such as a +reference to a Perl array (an "arrayref"). + +Consumers expecting a List B<must> consider a String as equivalent to a +List of length 1. + +=head2 Map + +A I<Map> is an unordered collection of zero or more data elements +("values"), indexed by associated String elements ("keys"). The Map's +value elements may be of mixed types. + +=head2 License String + +A I<License String> is a subtype of String with a restricted set of +values. Valid values are described in detail in the description of +the L</license> field. + +=head2 URL + +I<URL> is a subtype of String containing a Uniform Resource Locator or +Identifier. [ This type is called URL and not URI for historical reasons. ] + +=head2 Version + +A I<Version> is a subtype of String containing a value that describes +the version number of packages or distributions. Restrictions on format +are described in detail in the L</Version Formats> section. + +=head2 Version Range + +The I<Version Range> type is a subtype of String. It describes a range +of Versions that may be present or installed to fulfill prerequisites. +It is specified in detail in the L</Version Ranges> section. + +=head1 STRUCTURE + +The metadata structure is a data element of type Map. This section +describes valid keys within the Map. + +Any keys not described in this specification document (whether top-level +or within compound data structures described herein) are considered +I<custom keys> and B<must> begin with an "x" or "X" and be followed by an +underscore; i.e. they must match the pattern: C<< qr{\Ax_}i >>. If a +custom key refers to a compound data structure, subkeys within it do not +need an "x_" or "X_" prefix. + +Consumers of metadata may ignore any or all custom keys. All other keys +not described herein are invalid and should be ignored by consumers. +Producers must not generate or output invalid keys. + +For each key, an example is provided followed by a description. The +description begins with the version of spec in which the key was added +or in which the definition was modified, whether the key is I<required> +or I<optional> and the data type of the corresponding data element. +These items are in parentheses, brackets and braces, respectively. + +If a data type is a Map or Map subtype, valid subkeys will be described +as well. + +Some fields are marked I<Deprecated>. These are shown for historical +context and must not be produced in or consumed from any metadata structure +of version 2 or higher. + +=head2 REQUIRED FIELDS + +=head3 abstract + +Example: + + abstract => 'Build and install Perl modules' + +(Spec 1.2) [required] {String} + +This is a short description of the purpose of the distribution. + +=head3 author + +Example: + + author => [ 'Ken Williams <kwilliams@cpan.org>' ] + +(Spec 1.2) [required] {List of one or more Strings} + +This List indicates the person(s) to contact concerning the +distribution.

This field should be set to a false +value to indicate that prerequisites included in metadata may be +considered final and valid for static analysis. + +Note: when this field is true, post-configuration prerequisites are not +guaranteed to bear any relation whatsoever to those stated in the metadata, +and relying on them doing so is an error. See also +L</Prerequisites for dynamically configured distributions> in the implementors' +notes. + +This field explicitly B<does not> indicate whether installation may be +safely performed without using a Makefile or Build file, as there may be +special files to install or custom installation targets (e.g. for +dual-life modules that exist on CPAN as well as in the Perl core).

If the +C<version> field contains an underscore character, then +C<release_status> B<must not> be "stable." + +The C<release_status> field B<must> have one of the following values: + +=over + +=item stable + +This indicates an ordinary, "final" release that should be indexed by PAUSE +or other indexers. + +=item testing + +This indicates a "beta" release that is substantially complete, but has an +elevated risk of bugs and requires additional testing.

This release status may also be used +for "release candidate" versions of a distribution. + +=item unstable + +This indicates an "alpha" release that is under active development, but has +been released for early feedback or testing and may be missing features or +may have serious bugs. The distribution should not be installed over a +stable release without an explicit request or other confirmation from a +user. + +=back + +Consumers B<may> use this field to determine how to index the +distribution for CPAN or other repositories in addition to or in +replacement of heuristics based on version number or file name. + +=head3 version + +Example: + + version => '0.36' + +(Spec 1.0) [required] {Version} + +This field gives the version of the distribution to which the metadata +structure refers. + +=head2 OPTIONAL FIELDS + +=head3 description + +Example: + + description => "Module::Build is a system for " + .

See L</Merging and Resolving Prerequisites> for details on +merging prerequisites. + +I<Suggestion for disuse:> Because there is currently no way for a +distribution to specify a dependency on an optional feature of another +dependency, the use of C<optional_feature> is discouraged.

For +example, C<1.200> B<must not> be serialized as C<1.2>. Version +comparison should be delegated to the Perl L<version> module, version +0.80 or newer. + +Unless otherwise specified, version numbers B<must> appear in one of two +formats: + +=over + +=item Decimal versions + +Decimal versions are regular "decimal numbers", with some limitations. +They B<must> be non-negative and B<must> begin and end with a digit. A +single underscore B<may> be included, but B<must> be between two digits. +They B<must not> use exponential notation ("1.23e-2"). + + version => '1.234' # OK + version => '1.23_04' # OK + + version => '1.23_04_05' # Illegal + version => '1.' # Illegal + version => '.1' # Illegal + +=item Dotted-integer versions + +Dotted-integer (also known as dotted-decimal) versions consist of +positive integers separated by full stop characters (i.e. "dots", +"periods" or "decimal points"). This are equivalent in format to Perl +"v-strings", with some additional restrictions on form. They must be +given in "normal" form, which has a leading "v" character and at least +three integer components. To retain a one-to-one mapping with decimal +versions, all components after the first B<should> be restricted to the +range 0 to 999. The final component B<may> be separated by an +underscore character instead of a period. + + version => 'v1.2.3' # OK + version => 'v1.2_3' # OK + version => 'v1.2.3.4' # OK + version => 'v1.2.3_4' # OK + version => 'v2009.10.31' # OK + + version => 'v1.2' # Illegal + version => '1.2.3' # Illegal + version => 'v1.2_3_4' # Illegal + version => 'v1.2009.10.31' # Not recommended + +=back + +=head2 Version Ranges + +Some fields (prereq, optional_features) indicate the particular +version(s) of some other module that may be required as a prerequisite. +This section details the Version Range type used to provide this +information. + +The simplest format for a Version Range is just the version +number itself, e.g. C<2.4>. This means that B<at least> version 2.4 +must be present. To indicate that B<any> version of a prerequisite is +okay, even if the prerequisite doesn't define a version at all, use +the version C<0>. + +Alternatively, a version range B<may> use the operators E<lt> (less than), +E<lt>= (less than or equal), E<gt> (greater than), E<gt>= (greater than +or equal), == (equal), and != (not equal). For example, the +specification C<E<lt> 2.0> means that any version of the prerequisite +less than 2.0 is suitable. + +For more complicated situations, version specifications B<may> be AND-ed +together using commas. The specification C<E<gt>= 1.2, != 1.5, E<lt> +2.0> indicates a version that must be B<at least> 1.2, B<less than> 2.0, +and B<not equal to> 1.5. + +=head1 PREREQUISITES + +=head2 Prereq Spec + +The C<prereqs> key in the top-level metadata and within +C<optional_features> define the relationship between a distribution and +other packages. The prereq spec structure is a hierarchical data +structure which divides prerequisites into I<Phases> of activity in the +installation process and I<Relationships> that indicate how +prerequisites should be resolved. + +For example, to specify that C<Data::Dumper> is C<required> during the +C<test> phase, this entry would appear in the distribution metadata: + + prereqs => { + test => { + requires => { + 'Data::Dumper' => '2.00' + } + } + } + +=head3 Phases + +Requirements for regular use must be listed in the C<runtime> phase. +Other requirements should be listed in the earliest stage in which they +are required and consumers must accumulate and satisfy requirements +across phases before executing the activity. For example, C<build> +requirements must also be available during the C<test> phase. + + before action requirements that must be met + ---------------- -------------------------------- + perl Build.PL configure + perl Makefile.PL + + make configure, runtime, build + Build + + make test configure, runtime, build, test + Build test + +Consumers that install the distribution must ensure that +I<runtime> requirements are also installed and may install +dependencies from other phases. + + after action requirements that must be met + ---------------- -------------------------------- + make install runtime + Build install + +=over + +=item configure + +The configure phase occurs before any dynamic configuration has been +attempted. Libraries required by the configure phase B<must> be +available for use before the distribution building tool has been +executed. + +=item build + +The build phase is when the distribution's source code is compiled (if +necessary) and otherwise made ready for installation. + +=item test + +The test phase is when the distribution's automated test suite is run. +Any library that is needed only for testing and not for subsequent use +should be listed here. + +=item runtime + +The runtime phase refers not only to when the distribution's contents +are installed, but also to its continued use. Any library that is a +prerequisite for regular use of this distribution should be indicated +here. + +=item develop + +The develop phase's prereqs are libraries needed to work on the +distribution's source code as its author does. These tools might be +needed to build a release tarball, to run author-only tests, or to +perform other tasks related to developing new versions of the +distribution. + +=back + +=head3 Relationships + +=over + +=item requires + +These dependencies B<must> be installed for proper completion of the +phase. + +=item recommends + +Recommended dependencies are I<strongly> encouraged and should be +satisfied except in resource constrained environments. + +=item suggests + +These dependencies are optional, but are suggested for enhanced operation +of the described distribution. + +=item conflicts + +These libraries cannot be installed when the phase is in operation. +This is a very rare situation, and the C<conflicts> relationship should +be used with great caution, or not at all. + +=back + +=head2 Merging and Resolving Prerequisites + +Whenever metadata consumers merge prerequisites, either from different +phases or from C<optional_features>, they should merged in a way which +preserves the intended semantics of the prerequisite structure. Generally, +this means concatenating the version specifications using commas, as +described in the L<Version Ranges> section. + +Another subtle error that can occur in resolving prerequisites comes from +the way that modules in prerequisites are indexed to distribution files on +CPAN. When a module is deleted from a distribution, prerequisites calling +for that module could indicate an older distribution should be installed, +potentially overwriting files from a newer distribution. + +For example, as of Oct 31, 2009, the CPAN index file contained these +module-distribution mappings: + + Class::MOP 0.94 D/DR/DROLSKY/Class-MOP-0.94.tar.gz + Class::MOP::Class 0.94 D/DR/DROLSKY/Class-MOP-0.94.tar.gz + Class::MOP::Class::Immutable 0.04 S/ST/STEVAN/Class-MOP-0.36.tar.gz + +Consider the case where "Class::MOP" 0.94 is installed. If a +distribution specified "Class::MOP::Class::Immutable" as a prerequisite, +it could result in Class-MOP-0.36.tar.gz being installed, overwriting +any files from Class-MOP-0.94.tar.gz. + +Consumers of metadata B<should> test whether prerequisites would result +in installed module files being "downgraded" to an older version and +B<may> warn users or ignore the prerequisite that would cause such a +result. + +=head1 SERIALIZATION + +Distribution metadata should be serialized (as a hashref) as +JSON-encoded data and packaged with distributions as the file +F<META.json>. + +In the past, the distribution metadata structure had been packed with +distributions as F<META.yml>, a file in the YAML Tiny format (for which, +see L<YAML::Tiny>). Tools that consume distribution metadata from disk +should be capable of loading F<META.yml>, but should prefer F<META.json> +if both are found. + +=head1 NOTES FOR IMPLEMENTORS + +=head2 Extracting Version Numbers from Perl Modules + +To get the version number from a Perl module, consumers should use the +C<< MM->parse_version($file) >> method provided by +L<ExtUtils::MakeMaker> or L<Module::Metadata>. For example, for the +module given by C<$mod>, the version may be retrieved in one of the +following ways: + + # via ExtUtils::MakeMaker + my $file = MM->_installed_file_for_module($mod); + my $version = MM->parse_version($file) + +The private C<_installed_file_for_module> method may be replaced with +other methods for locating a module in C<@INC>. + + # via Module::Metadata + my $info = Module::Metadata->new_from_module($mod); + my $version = $info->version; + +If only a filename is available, the following approach may be used: + + # via Module::Build + my $info = Module::Metadata->new_from_file($file); + my $version = $info->version; + +=head2 Comparing Version Numbers + +The L<version> module provides the most reliable way to compare version +numbers in all the various ways they might be provided or might exist +within modules. Given two strings containing version numbers, C<$v1> and +C<$v2>, they should be converted to C<version> objects before using +ordinary comparison operators. For example: + + use version; + if ( version->new($v1) <=> version->new($v2) ) { + print "Versions are not equal\n"; + } + +If the only comparison needed is whether an installed module is of a +sufficiently high version, a direct test may be done using the string +form of C<eval> and the C<use> function. For example, for module C<$mod> +and version prerequisite C<$prereq>: + + if ( eval "use $mod $prereq (); 1" ) { + print "Module $mod version is OK.\n"; + } + +If the values of C<$mod> and C<$prereq> have not been scrubbed, however, +this presents security implications. + +=head2 Prerequisites for dynamically configured distributions + +When C<dynamic_config> is true, it is an error to presume that the +prerequisites given in distribution metadata will have any relationship +whatsoever to the actual prerequisites of the distribution. + +In practice, however, one can generally expect such prerequisites to be +one of two things: + +=over 4 + +=item * + +The minimum prerequisites for the distribution, to which dynamic configuration will only add items + +=item * + +Whatever the distribution configured with on the releaser's machine at release time + +=back + +The second case often turns out to have identical results to the first case, +albeit only by accident. + +As such, consumers may use this data for informational analysis, but +presenting it to the user as canonical or relying on it as such is +invariably the height of folly. + +=head2 Indexing distributions a la PAUSE + +While no_index tells you what must be ignored when indexing, this spec holds +no opinion on how you should get your initial candidate list of things to +possibly index. For "normal" distributions you might consider simply indexing +the contents of lib/, but there are many fascinating oddities on CPAN and +many dists from the days when it was normal to put the main .pm file in the +root of the distribution archive - so PAUSE currently indexes all .pm and .PL +files that are not either (a) specifically excluded by no_index (b) in +C<inc>, C<xt>, or C<t> directories, or common 'mistake' directories such as +C<perl5>. + +Or: If you're trying to be PAUSE-like, make sure you skip C<inc>, C<xt> and +C<t> as well as anything marked as no_index. + +Also remember: If the META file contains a provides field, you shouldn't be +indexing anything in the first place - just use that. + +=head1 SEE ALSO + +=over 4 + +=item * + +CPAN, L<http://www.cpan.org/> + +=item * + +JSON, L<http://json.org/> + +=item * + +YAML, L<http://www.yaml.org/> + +=item * + +L<CPAN> + +=item * + +L<CPANPLUS> + +=item * + +L<ExtUtils::MakeMaker> + +=item * + +L<Module::Build> + +=item * + +L<Module::Install> + +=item * + +L<CPAN::Meta::History::Meta_1_4> + +=back + +=head1 HISTORY + +Ken Williams wrote the original CPAN Meta Spec (also known as the +"META.yml spec") in 2003 and maintained it through several revisions +with input from various members of the community.

It is recommended that getcwd (or another +*cwd() function) be used in I<all> code to ensure portability. + +By default, it exports the functions cwd(), getcwd(), fastcwd(), and +fastgetcwd() (and, on Win32, getdcwd()) into the caller's namespace. + + +=head2 getcwd and friends + +Each of these functions are called without arguments and return the +absolute path of the current working directory. + +=over 4 + +=item getcwd + + my $cwd = getcwd(); + +Returns the current working directory. On error returns C<undef>, +with C<$!> set to indicate the error. + +Exposes the POSIX function getcwd(3) or re-implements it if it's not +available. + +=item cwd + + my $cwd = cwd(); + +The cwd() is the most natural form for the current architecture. For +most systems it is identical to `pwd` (but without the trailing line +terminator). + +=item fastcwd + + my $cwd = fastcwd(); + +A more dangerous version of getcwd(), but potentially faster. + +It might conceivably chdir() you out of a directory that it can't +chdir() you back into. If fastcwd encounters a problem it will return +undef but will probably leave you in a different directory. For a +measure of extra security, if everything appears to have worked, the +fastcwd() function will check that it leaves you in the same directory +that it started in. If it has changed it will C<die> with the message +"Unstable directory path, current directory changed +unexpectedly". That should never happen. + +=item fastgetcwd + + my $cwd = fastgetcwd(); + +The fastgetcwd() function is provided as a synonym for cwd(). + +=item getdcwd + + my $cwd = getdcwd(); + my $cwd = getdcwd('C:'); + +The getdcwd() function is also provided on Win32 to get the current working +directory on the specified drive, since Windows maintains a separate current +working directory for each drive. If no drive is specified then the current +drive is assumed. + +This function simply calls the Microsoft C library _getdcwd() function. + +=back + + +=head2 abs_path and friends + +These functions are exported only on request. They each take a single +argument and return the absolute pathname for it. If no argument is +given they'll use the current working directory. + +=over 4 + +=item abs_path + + my $abs_path = abs_path($file); + +Uses the same algorithm as getcwd(). Symbolic links and relative-path +components ("." and "..") are resolved to return the canonical +pathname, just like realpath(3).

These will read and deserialize CPAN metafiles, and +are described below in detail. + +B<Parse::CPAN::Meta> provides a legacy API of only two functions, +based on the YAML functions of the same name. Wherever possible, +identical calling semantics are used. These may only be used with YAML sources. + +All error reporting is done with exceptions (die'ing). + +Note that META files are expected to be in UTF-8 encoding, only.

If C<CPAN_META_JSON_BACKEND> +is set, this will be whatever that's set to. If not, this will either +be L<JSON::PP> or L<JSON>.

If the +C<CPAN_META_JSON_DECODER> environment variable exists, this is expected to +be the name of a loadable module that provides a C<decode_json> subroutine, +which will then be used for deserialization. Relying only on the existence +of said subroutine allows for maximum compatibility, since this API is +provided by all of L<JSON::PP>, L<JSON::XS>, L<Cpanel::JSON::XS>, +L<JSON::MaybeXS>, L<JSON::Tiny>, and L<Mojo::JSON>. + +=head2 CPAN_META_JSON_BACKEND + +By default, L<JSON::PP> will be used for deserializing JSON data. If the +C<CPAN_META_JSON_BACKEND> environment variable exists, this is expected to +be the name of a loadable module that provides the L<JSON> API, since +downstream code expects to be able to call C<new> on this class. As such, +while L<JSON::PP>, L<JSON::XS>, L<Cpanel::JSON::XS> and L<JSON::MaybeXS> will +work for this, to use L<Mojo::JSON> or L<JSON::Tiny> for decoding requires +setting L</CPAN_META_JSON_DECODER>. + +=head2 PERL_JSON_BACKEND + +If the C<CPAN_META_JSON_BACKEND> environment variable does not exist, and if +C<PERL_JSON_BACKEND> environment variable exists, is true and is not +"JSON::PP", then the L<JSON> module (version 2.5 or greater) will be loaded and +used to interpret C<PERL_JSON_BACKEND>.

Glock" <flavio.glock@booking.com> Date: Sat, 14 Mar 2026 10:59:41 +0100 Subject: [PATCH 03/17] Fix parser bugs for CPAN.pm compatibility 1. Fix file test operators with function call operands (-f func()) - Store operand in local variable before pushing operator string - Avoids ASM stack frame computation errors at merge points 2. Fix block argument parsing for undefined functions (func { } @args) - When function is not yet defined and followed by {, use &@ prototype - Matches Perl5 behavior: { } after function call is treated as block 3. Fix file test with qualified package names (-f CPAN::find_perl) - Do not treat identifier as bareword filehandle if followed by :: - Allows parsing of qualified subroutine calls in file test operands These fixes enable loading CPAN.pm which uses all three patterns.

Glock" <flavio.glock@booking.com> Date: Sat, 14 Mar 2026 14:18:56 +0100 Subject: [PATCH 15/17] Fix regex POSIX class followed by hyphen in character class Pattern like [[:digit:]-[:alpha:]] should match digits, literal hyphen, and alpha chars. The previous fix for [A-Z-0-9] incorrectly treated the hyphen before a POSIX class as a range operator. Two fixes: 1. When processing '-', check if next char is start of POSIX class ([ followed by :) and treat the hyphen as literal if so 2. After processing a POSIX class, set lastChar = -1 since POSIX classes can't be range endpoints This restores re/regexp.t test 937 which tests [[:digit:]-[:alpha:]].
