2367 | =head1 NAME |
2368 | |
2369 | CPAN - query, download and build perl modules from CPAN sites |
2370 | |
2371 | =head1 SYNOPSIS |
2372 | |
2373 | Interactive mode: |
2374 | |
2375 | perl -MCPAN -e shell; |
2376 | |
2377 | Batch mode: |
2378 | |
2379 | use CPAN; |
2380 | |
10b2abe6 |
2381 | autobundle, clean, install, make, recompile, test |
5f05dabc |
2382 | |
2383 | =head1 DESCRIPTION |
2384 | |
10b2abe6 |
2385 | The CPAN module is designed to automate the make and install of perl |
42d3b621 |
2386 | modules and extensions. It includes some searching capabilities and |
2387 | knows how to use Net::FTP or LWP (or lynx or an external ftp client) |
2388 | to fetch the raw data from the net. |
5f05dabc |
2389 | |
2390 | Modules are fetched from one or more of the mirrored CPAN |
2391 | (Comprehensive Perl Archive Network) sites and unpacked in a dedicated |
2392 | directory. |
2393 | |
2394 | The CPAN module also supports the concept of named and versioned |
2395 | 'bundles' of modules. Bundles simplify the handling of sets of |
2396 | related modules. See BUNDLES below. |
2397 | |
2398 | The package contains a session manager and a cache manager. There is |
2399 | no status retained between sessions. The session manager keeps track |
2400 | of what has been fetched, built and installed in the current |
2401 | session. The cache manager keeps track of the disk space occupied by |
42d3b621 |
2402 | the make processes and deletes excess space according to a simple FIFO |
2403 | mechanism. |
5f05dabc |
2404 | |
10b2abe6 |
2405 | All methods provided are accessible in a programmer style and in an |
2406 | interactive shell style. |
2407 | |
5f05dabc |
2408 | =head2 Interactive Mode |
2409 | |
2410 | The interactive mode is entered by running |
2411 | |
2412 | perl -MCPAN -e shell |
2413 | |
2414 | which puts you into a readline interface. You will have most fun if |
2415 | you install Term::ReadKey and Term::ReadLine to enjoy both history and |
2416 | completion. |
2417 | |
2418 | Once you are on the command line, type 'h' and the rest should be |
2419 | self-explanatory. |
2420 | |
10b2abe6 |
2421 | The most common uses of the interactive modes are |
2422 | |
2423 | =over 2 |
2424 | |
2425 | =item Searching for authors, bundles, distribution files and modules |
2426 | |
2427 | There are corresponding one-letter commands C<a>, C<b>, C<d>, and C<m> |
42d3b621 |
2428 | for each of the four categories and another, C<i> for any of the |
2429 | mentioned four. Each of the four entities is implemented as a class |
2430 | with slightly differing methods for displaying an object. |
10b2abe6 |
2431 | |
2432 | Arguments you pass to these commands are either strings matching exact |
2433 | the identification string of an object or regular expressions that are |
2434 | then matched case-insensitively against various attributes of the |
2435 | objects. The parser recognizes a regualar expression only if you |
2436 | enclose it between two slashes. |
2437 | |
2438 | The principle is that the number of found objects influences how an |
2439 | item is displayed. If the search finds one item, we display the result |
2440 | of object-E<gt>as_string, but if we find more than one, we display |
2441 | each as object-E<gt>as_glimpse. E.g. |

2458 | |
2459 | =item make, test, install, clean modules or distributions |
2460 | |
2461 | The four commands do indeed exist just as written above. Each of them |
2462 | takes as many arguments as provided and investigates for each what it |
2463 | might be. Is it a distribution file (recognized by embedded slashes), |
2464 | this file is being processed. Is it a module, CPAN determines the |
2465 | distribution file where this module is included and processes that. |
2466 | |
42d3b621 |
2467 | Any C<make> and C<test> are run unconditionally. A |
2468 | |
2469 | C<install E<lt>distribution_fileE<gt>> |
2470 | |
2471 | also is run unconditionally. But for |
2472 | |
2473 | C<install E<lt>moduleE<gt>> |
2474 | |
2475 | CPAN checks if an install is actually needed for it and prints |
2476 | I<Foo up to date> in case the module doesnE<39>t need to be updated. |
10b2abe6 |
2477 | |
2478 | CPAN also keeps track of what it has done within the current session |
2479 | and doesnE<39>t try to build a package a second time regardless if it |
2480 | succeeded or not. The C<force > command takes as first argument the |
2481 | method to invoke (currently: make, test, or install) and executes the |
2482 | command from scratch. |
2483 | |
2484 | Example: |
2485 | |
2486 | cpan> install OpenGL |
2487 | OpenGL is up to date. |
2488 | cpan> force install OpenGL |
2489 | Running make |
2490 | OpenGL-0.4/ |
2491 | OpenGL-0.4/COPYRIGHT |

2496 | =head2 CPAN::Shell |
2497 | |
2498 | The commands that are available in the shell interface are methods in |
2499 | the package CPAN::Shell. If you enter the shell command, all your |
10b2abe6 |
2500 | input is split by the Text::ParseWords::shellwords() routine which |
2501 | acts like most shells do. The first word is being interpreted as the |
2502 | method to be called and the rest of the words are treated as arguments |
2503 | to this method. |
2504 | |
2505 | =head2 ProgrammerE<39>s interface |
5f05dabc |
2506 | |
10b2abe6 |
2507 | If you do not enter the shell, the available shell commands are both |
2508 | available as methods (C<CPAN::Shell-E<gt>install(...)>) and as |
2509 | functions in the calling package (C<install(...)>). The |
2510 | programmerE<39>s interface has beta status. Do not heavily rely on it, |
42d3b621 |
2511 | changes may still be necessary. |
5f05dabc |
2512 | |
2513 | =head2 Cache Manager |
2514 | |
2515 | Currently the cache manager only keeps track of the build directory |
2516 | ($CPAN::Config->{build_dir}). It is a simple FIFO mechanism that |
42d3b621 |
2517 | deletes complete directories below C<build_dir> as soon as the size of |
5f05dabc |
2518 | all directories there gets bigger than $CPAN::Config->{build_cache} |
2519 | (in MB). The contents of this cache may be used for later |
2520 | re-installations that you intend to do manually, but will never be |
10b2abe6 |
2521 | trusted by CPAN itself. This is due to the fact that the user might |
2522 | use these directories for building modules on different architectures. |
5f05dabc |
2523 | |
2524 | There is another directory ($CPAN::Config->{keep_source_where}) where |
2525 | the original distribution files are kept. This directory is not |
2526 | covered by the cache manager and must be controlled by the user. If |
2527 | you choose to have the same directory as build_dir and as |
2528 | keep_source_where directory, then your sources will be deleted with |
2529 | the same fifo mechanism. |
2530 | |
2531 | =head2 Bundles |
2532 | |
2533 | A bundle is just a perl module in the namespace Bundle:: that does not |
2534 | define any functions or methods. It usually only contains documentation. |
2535 | |
2536 | It starts like a perl module with a package declaration and a $VERSION |
2537 | variable. After that the pod section looks like any other pod with the |
10b2abe6 |
2538 | only difference, that I<one special pod section> exists starting with |
2539 | (verbatim): |
5f05dabc |
2540 | |
2541 | =head1 CONTENTS |
2542 | |
2543 | In this pod section each line obeys the format |
2544 | |
2545 | Module_Name [Version_String] [- optional text] |
2546 | |
2547 | The only required part is the first field, the name of a module |
2548 | (eg. Foo::Bar, ie. I<not> the name of the distribution file). The rest |
2549 | of the line is optional. The comment part is delimited by a dash just |
2550 | as in the man page header. |
2551 | |
2552 | The distribution of a bundle should follow the same convention as |
42d3b621 |
2553 | other distributions. |
5f05dabc |
2554 | |
2555 | Bundles are treated specially in the CPAN package. If you say 'install |
2556 | Bundle::Tkkit' (assuming such a bundle exists), CPAN will install all |
2557 | the modules in the CONTENTS section of the pod. You can install your |
2558 | own Bundles locally by placing a conformant Bundle file somewhere into |
2559 | your @INC path. The autobundle() command which is available in the |
2560 | shell interface does that for you by including all currently installed |
2561 | modules in a snapshot bundle file. |
2562 | |
10b2abe6 |
2563 | There is a meaningless Bundle::Demo available on CPAN. Try to install |
2564 | it, it usually does no harm, just demonstrates what the Bundle |
2565 | interface looks like. |
2566 | |
5f05dabc |
2567 | =head2 autobundle |
2568 | |
42d3b621 |
2569 | C<autobundle> writes a bundle file into the |
2570 | C<$CPAN::Config-E<gt>{cpan_home}/Bundle> directory. The file contains |
2571 | a list of all modules that are both available from CPAN and currently |
5f05dabc |
2572 | installed within @INC. The name of the bundle file is based on the |
2573 | current date and a counter. |
2574 | |
5f05dabc |
2575 | =head2 recompile |
2576 | |
2577 | recompile() is a very special command in that it takes no argument and |
2578 | runs the make/test/install cycle with brute force over all installed |
2579 | dynamically loadable extensions (aka XS modules) with 'force' in |
2580 | effect. Primary purpose of this command is to act as a rescue in case |
2581 | your perl breaks binary compatibility. If one of the modules that CPAN |
2582 | uses is in turn depending on binary compatibility (so you cannot run |
2583 | CPAN commands), then you should try the CPAN::Nox module for recovery. |
2584 | |
42d3b621 |
2585 | Another popular use for recompile is to finish a network |
10b2abe6 |
2586 | installation. Imagine, you have a common source tree for two different |
2587 | architectures. You decide to do a completely independent fresh |
2588 | installation. You start on one architecture with the help of a Bundle |
2589 | file produced earlier. CPAN installs the whole Bundle for you, but |
2590 | when you try to repeat the job on the second architecture, CPAN |
2591 | responds with a C<"Foo up to date"> message for all modules. So you |
2592 | will be glad to run recompile in the second architecture and |
2593 | youE<39>re done. |
2594 | |
5f05dabc |
2595 | =head1 CONFIGURATION |
2596 | |
2597 | When the CPAN module is installed a site wide configuration file is |
2598 | created as CPAN/Config.pm. The default values defined there can be |
2599 | overridden in another configuration file: CPAN/MyConfig.pm. You can |
2600 | store this file in $HOME/.cpan/CPAN/MyConfig.pm if you want, because |
2601 | $HOME/.cpan is added to the search path of the CPAN module before the |
2602 | use() or require() statements. |
2603 | |
2604 | Currently the following keys in the hash reference $CPAN::Config are |
2605 | defined: |
2606 | |
42d3b621 |
2607 | build_cache size of cache for directories to build modules |
2608 | build_dir locally accessible directory to build modules |
2609 | index_expire after how many days refetch index files |
2610 | cpan_home local directory reserved for this package |
2611 | gzip location of external program gzip |
2612 | inactivity_timeout breaks interactive Makefile.PLs after that |
2613 | many seconds inactivity. Set to 0 to never break. |
5f05dabc |
2614 | inhibit_startup_message |
42d3b621 |
2615 | if true, does not print the startup message |
2616 | keep_source keep the source in a local directory? |
2617 | keep_source_where where keep the source (if we do) |
2618 | make location of external program make |
2619 | make_arg arguments that should always be passed to 'make' |
2620 | make_install_arg same as make_arg for 'make install' |
2621 | makepl_arg arguments passed to 'perl Makefile.PL' |
2622 | pager location of external program more (or any pager) |
2623 | tar location of external program tar |
2624 | unzip location of external program unzip |
2625 | urllist arrayref to nearby CPAN sites (or equivalent locations) |
5f05dabc |
2626 | |
2627 | You can set and query each of these options interactively in the cpan |
2628 | shell with the command set defined within the C<o conf> command: |
2629 | |
2630 | =over 2 |
2631 | |
2632 | =item o conf E<lt>scalar optionE<gt> |
2633 | |
2634 | prints the current value of the I<scalar option> |
2635 | |
2636 | =item o conf E<lt>scalar optionE<gt> E<lt>valueE<gt> |
2637 | |
2638 | Sets the value of the I<scalar option> to I<value> |
2639 | |
2640 | =item o conf E<lt>list optionE<gt> |
2641 | |
2642 | prints the current value of the I<list option> in MakeMaker's |
2643 | neatvalue format. |
2644 | |
2645 | =item o conf E<lt>list optionE<gt> [shift|pop] |
2646 | |
2647 | shifts or pops the array in the I<list option> variable |
2648 | |
2649 | =item o conf E<lt>list optionE<gt> [unshift|push|splice] E<lt>listE<gt> |
2650 | |
42d3b621 |
2651 | works like the corresponding perl commands. |

2655 | =head1 SECURITY |
2656 | |
2657 | There's no strong security layer in CPAN.pm. CPAN.pm helps you to |
2658 | install foreign, unmasked, unsigned code on your machine. We compare |
2659 | to a checksum that comes from the net just as the distribution file |
2660 | itself. If somebody has managed to tamper with the distribution file, |
2661 | they may have as well tampered with the CHECKSUMS file. Future |
42d3b621 |
2662 | development will go towards strong authentification. |
5f05dabc |
2663 | |
2664 | =head1 EXPORT |
2665 | |
2666 | Most functions in package CPAN are exported per default. The reason |
2667 | for this is that the primary use is intended for the cpan shell or for |
2668 | oneliners. |
2669 | |
2670 | =head1 Debugging |
2671 | |
2672 | The debugging of this module is pretty difficult, because we have |
2673 | interferences of the software producing the indices on CPAN, of the |
2674 | mirroring process on CPAN, of packaging, of configuration, of |
2675 | synchronicity, and of bugs within CPAN.pm. |
2676 | |
2677 | In interactive mode you can try "o debug" which will list options for |
2678 | debugging the various parts of the package. The output may not be very |
2679 | useful for you as it's just a byproduct of my own testing, but if you |
2680 | have an idea which part of the package may have a bug, it's sometimes |
2681 | worth to give it a try and send me more specific output. You should |
2682 | know that "o debug" has built-in completion support. |
2683 | |
2684 | =head2 Prerequisites |
2685 | |
2686 | If you have a local mirror of CPAN and can access all files with |
2687 | "file:" URLs, then you only need perl5.003 to run this |
42d3b621 |
2688 | module. Otherwise Net::FTP is recommended. LWP may be required for |
5f05dabc |
2689 | non-UNIX systems or if your nearest CPAN site is associated with an |
2690 | URL that is not C<ftp:>. |
2691 | |
42d3b621 |
2692 | If you have neither Net::FTP nor LWP, there is a fallback mechanism |
2693 | implemented for an external ftp command or for an external lynx |
2694 | command. |
2695 | |
5f05dabc |
2696 | This module presumes that all packages on CPAN |
2697 | |
2698 | =over 2 |
2699 | |
2700 | =item * |
2701 | |
2702 | declare their $VERSION variable in an easy to parse manner. This |
2703 | prerequisite can hardly be relaxed because it consumes by far too much |
2704 | memory to load all packages into the running program just to determine |
2705 | the $VERSION variable . Currently all programs that are dealing with |
42d3b621 |
2706 | version use something like this |
5f05dabc |
2707 | |
2708 | perl -MExtUtils::MakeMaker -le \ |
2709 | 'print MM->parse_version($ARGV[0])' filename |
2710 | |
42d3b621 |
2711 | If you are author of a package and wonder if your $VERSION can be |
5f05dabc |
2712 | parsed, please try the above method. |
2713 | |
2714 | =item * |
2715 | |
2716 | come as compressed or gzipped tarfiles or as zip files and contain a |
2717 | Makefile.PL (well we try to handle a bit more, but without much |
2718 | enthusiasm). |
