2812 | CPAN - query, download and build perl modules from CPAN sites |

2815 | |
2816 | Interactive mode: |
2817 | |
2818 | perl -MCPAN -e shell; |
2819 | |
2820 | Batch mode: |

5f05dabc |
2825 | |
2826 | =head1 DESCRIPTION |
2827 | |
10b2abe6 |
2828 | The CPAN module is designed to automate the make and install of perl |
42d3b621 |
2829 | modules and extensions. It includes some searching capabilities and |
2830 | knows how to use Net::FTP or LWP (or lynx or an external ftp client) |
2831 | to fetch the raw data from the net. |
5f05dabc |
2832 | |
2833 | Modules are fetched from one or more of the mirrored CPAN |
2834 | (Comprehensive Perl Archive Network) sites and unpacked in a dedicated |
2835 | directory. |
2836 | |
2837 | The CPAN module also supports the concept of named and versioned |
2838 | 'bundles' of modules. Bundles simplify the handling of sets of |
2839 | related modules. See BUNDLES below. |
2840 | |
2841 | The package contains a session manager and a cache manager. There is |
2842 | no status retained between sessions. The session manager keeps track |
2843 | of what has been fetched, built and installed in the current |
2844 | session. The cache manager keeps track of the disk space occupied by |
42d3b621 |
2845 | the make processes and deletes excess space according to a simple FIFO |
2846 | mechanism. |
5f05dabc |
2847 | |
10b2abe6 |
2848 | All methods provided are accessible in a programmer style and in an |
2849 | interactive shell style. |
2850 | |
5f05dabc |
2851 | =head2 Interactive Mode |
2852 | |
2853 | The interactive mode is entered by running |
2854 | |
2855 | perl -MCPAN -e shell |
2856 | |
2857 | which puts you into a readline interface. You will have most fun if |
2858 | you install Term::ReadKey and Term::ReadLine to enjoy both history and |
2859 | completion. |
2860 | |
2861 | Once you are on the command line, type 'h' and the rest should be |
2862 | self-explanatory. |
2863 | |
10b2abe6 |
2864 | The most common uses of the interactive modes are |
2865 | |
2866 | =over 2 |
2867 | |
2868 | =item Searching for authors, bundles, distribution files and modules |
2869 | |
2870 | There are corresponding one-letter commands C<a>, C<b>, C<d>, and C<m> |
42d3b621 |
2871 | for each of the four categories and another, C<i> for any of the |
2872 | mentioned four. Each of the four entities is implemented as a class |
2873 | with slightly differing methods for displaying an object. |
10b2abe6 |
2874 | |
2875 | Arguments you pass to these commands are either strings matching exact |
2876 | the identification string of an object or regular expressions that are |
2877 | then matched case-insensitively against various attributes of the |
2878 | objects. The parser recognizes a regualar expression only if you |
2879 | enclose it between two slashes. |
2880 | |
2881 | The principle is that the number of found objects influences how an |
2882 | item is displayed. If the search finds one item, we display the result |
2883 | of object-E<gt>as_string, but if we find more than one, we display |
2884 | each as object-E<gt>as_glimpse. E.g. |

2902 | =item make, test, install, clean modules or distributions |
10b2abe6 |
2903 | |
da199366 |
2904 | These commands do indeed exist just as written above. Each of them |
2905 | takes any number of arguments and investigates for each what it might |
2906 | be. Is it a distribution file (recognized by embedded slashes), this |
2907 | file is being processed. Is it a module, CPAN determines the |
10b2abe6 |
2908 | distribution file where this module is included and processes that. |
2909 | |
da199366 |
2910 | Any C<make>, C<test>, and C<readme> are run unconditionally. A |
42d3b621 |
2911 | |
05454584 |
2912 | install <distribution_file> |
42d3b621 |
2913 | |
2914 | also is run unconditionally. But for |
2915 | |
05454584 |
2916 | install <module> |
42d3b621 |
2917 | |
2918 | CPAN checks if an install is actually needed for it and prints |
2919 | I<Foo up to date> in case the module doesnE<39>t need to be updated. |
10b2abe6 |
2920 | |
2921 | CPAN also keeps track of what it has done within the current session |
2922 | and doesnE<39>t try to build a package a second time regardless if it |
2923 | succeeded or not. The C<force > command takes as first argument the |
2924 | method to invoke (currently: make, test, or install) and executes the |
2925 | command from scratch. |
2926 | |
2927 | Example: |
2928 | |
2929 | cpan> install OpenGL |
2930 | OpenGL is up to date. |
2931 | cpan> force install OpenGL |
2932 | Running make |
2933 | OpenGL-0.4/ |
2934 | OpenGL-0.4/COPYRIGHT |
2935 | [...] |
2936 | |
da199366 |
2937 | =item readme, look module or distribution |
2938 | |
2939 | These two commands take only one argument, be it a module or a |
2940 | distribution file. C<readme> displays the README of the associated |
2941 | distribution file. C<Look> gets and untars (if not yet done) the |
2942 | distribution file, changes to the appropriate directory and opens a |
2943 | subshell process in that directory. |

2947 | =head2 CPAN::Shell |
2948 | |
2949 | The commands that are available in the shell interface are methods in |
2950 | the package CPAN::Shell. If you enter the shell command, all your |
10b2abe6 |
2951 | input is split by the Text::ParseWords::shellwords() routine which |
2952 | acts like most shells do. The first word is being interpreted as the |
2953 | method to be called and the rest of the words are treated as arguments |
2954 | to this method. |
2955 | |
da199366 |
2956 | =head2 autobundle |
2957 | |
2958 | C<autobundle> writes a bundle file into the |
2959 | C<$CPAN::Config-E<gt>{cpan_home}/Bundle> directory. The file contains |
2960 | a list of all modules that are both available from CPAN and currently |
2961 | installed within @INC. The name of the bundle file is based on the |
2962 | current date and a counter. |
2963 | |
2964 | =head2 recompile |
2965 | |
2966 | recompile() is a very special command in that it takes no argument and |
2967 | runs the make/test/install cycle with brute force over all installed |
2968 | dynamically loadable extensions (aka XS modules) with 'force' in |
2969 | effect. Primary purpose of this command is to finish a network |
2970 | installation. Imagine, you have a common source tree for two different |
2971 | architectures. You decide to do a completely independent fresh |
2972 | installation. You start on one architecture with the help of a Bundle |
2973 | file produced earlier. CPAN installs the whole Bundle for you, but |
2974 | when you try to repeat the job on the second architecture, CPAN |
2975 | responds with a C<"Foo up to date"> message for all modules. So you |
2976 | will be glad to run recompile in the second architecture and |
2977 | youE<39>re done. |
2978 | |
2979 | Another popular use for C<recompile> is to act as a rescue in case your |
2980 | perl breaks binary compatibility. If one of the modules that CPAN uses |
2981 | is in turn depending on binary compatibility (so you cannot run CPAN |
2982 | commands), then you should try the CPAN::Nox module for recovery. |
2983 | |
10b2abe6 |
2984 | =head2 ProgrammerE<39>s interface |
5f05dabc |
2985 | |
10b2abe6 |
2986 | If you do not enter the shell, the available shell commands are both |
2987 | available as methods (C<CPAN::Shell-E<gt>install(...)>) and as |
2988 | functions in the calling package (C<install(...)>). The |
2989 | programmerE<39>s interface has beta status. Do not heavily rely on it, |
42d3b621 |
2990 | changes may still be necessary. |
5f05dabc |
2991 | |
2992 | =head2 Cache Manager |
2993 | |
2994 | Currently the cache manager only keeps track of the build directory |
2995 | ($CPAN::Config->{build_dir}). It is a simple FIFO mechanism that |
42d3b621 |
2996 | deletes complete directories below C<build_dir> as soon as the size of |
5f05dabc |
2997 | all directories there gets bigger than $CPAN::Config->{build_cache} |
2998 | (in MB). The contents of this cache may be used for later |
2999 | re-installations that you intend to do manually, but will never be |
10b2abe6 |
3000 | trusted by CPAN itself. This is due to the fact that the user might |
3001 | use these directories for building modules on different architectures. |
5f05dabc |
3002 | |
3003 | There is another directory ($CPAN::Config->{keep_source_where}) where |
3004 | the original distribution files are kept. This directory is not |
3005 | covered by the cache manager and must be controlled by the user. If |
3006 | you choose to have the same directory as build_dir and as |
3007 | keep_source_where directory, then your sources will be deleted with |
3008 | the same fifo mechanism. |

3010 | =head2 Bundles |
3011 | |
3012 | A bundle is just a perl module in the namespace Bundle:: that does not |
3013 | define any functions or methods. It usually only contains documentation. |
3014 | |
3015 | It starts like a perl module with a package declaration and a $VERSION |
3016 | variable. After that the pod section looks like any other pod with the |
10b2abe6 |
3017 | only difference, that I<one special pod section> exists starting with |
3018 | (verbatim): |
5f05dabc |
3019 | |
3020 | =head1 CONTENTS |
3021 | |
3022 | In this pod section each line obeys the format |
3023 | |
3024 | Module_Name [Version_String] [- optional text] |
3025 | |
3026 | The only required part is the first field, the name of a module |
3027 | (eg. Foo::Bar, ie. I<not> the name of the distribution file). The rest |
3028 | of the line is optional. The comment part is delimited by a dash just |
3029 | as in the man page header. |
3030 | |
3031 | The distribution of a bundle should follow the same convention as |
42d3b621 |
3032 | other distributions. |
5f05dabc |
3033 | |
3034 | Bundles are treated specially in the CPAN package. If you say 'install |
3035 | Bundle::Tkkit' (assuming such a bundle exists), CPAN will install all |
3036 | the modules in the CONTENTS section of the pod. You can install your |
3037 | own Bundles locally by placing a conformant Bundle file somewhere into |
3038 | your @INC path. The autobundle() command which is available in the |
3039 | shell interface does that for you by including all currently installed |
3040 | modules in a snapshot bundle file. |
3041 | |
10b2abe6 |
3042 | There is a meaningless Bundle::Demo available on CPAN. Try to install |
3043 | it, it usually does no harm, just demonstrates what the Bundle |
3044 | interface looks like. |

3046 | =head2 Prerequisites |
5f05dabc |
3047 | |
da199366 |
3048 | If you have a local mirror of CPAN and can access all files with |
3049 | "file:" URLs, then you only need a perl better than perl5.003 to run |
3050 | this module. Otherwise Net::FTP is strongly recommended. LWP may be |
3051 | required for non-UNIX systems or if your nearest CPAN site is |
3052 | associated with an URL that is not C<ftp:>. |
5f05dabc |
3053 | |
da199366 |
3054 | If you have neither Net::FTP nor LWP, there is a fallback mechanism |
3055 | implemented for an external ftp command or for an external lynx |
3056 | command. |
5f05dabc |
3057 | |
da199366 |
3058 | This module presumes that all packages on CPAN |
5f05dabc |
3059 | |
da199366 |
3060 | =over 2 |
3061 | |
3062 | =item * |
3063 | |
3064 | declare their $VERSION variable in an easy to parse manner. This |
3065 | prerequisite can hardly be relaxed because it consumes by far too much |
3066 | memory to load all packages into the running program just to determine |
3067 | the $VERSION variable . Currently all programs that are dealing with |
3068 | version use something like this |
3069 | |
3070 | perl -MExtUtils::MakeMaker -le \ |
3071 | 'print MM->parse_version($ARGV[0])' filename |
3072 | |
3073 | If you are author of a package and wonder if your $VERSION can be |
3074 | parsed, please try the above method. |
3075 | |
3076 | =item * |
3077 | |
3078 | come as compressed or gzipped tarfiles or as zip files and contain a |
3079 | Makefile.PL (well we try to handle a bit more, but without much |
3080 | enthusiasm). |
3081 | |
3082 | =back |
3083 | |
3084 | =head2 Debugging |
3085 | |
3086 | The debugging of this module is pretty difficult, because we have |
3087 | interferences of the software producing the indices on CPAN, of the |
3088 | mirroring process on CPAN, of packaging, of configuration, of |
3089 | synchronicity, and of bugs within CPAN.pm. |
3090 | |
3091 | In interactive mode you can try "o debug" which will list options for |
3092 | debugging the various parts of the package. The output may not be very |
3093 | useful for you as it's just a byproduct of my own testing, but if you |
3094 | have an idea which part of the package may have a bug, it's sometimes |
3095 | worth to give it a try and send me more specific output. You should |
3096 | know that "o debug" has built-in completion support. |
3097 | |
3098 | =head2 Floppy, Zip, and all that Jazz |
3099 | |
3100 | CPAN.pm works nicely without network too. If you maintain machines |
3101 | that are not networked at all, you should consider working with file: |
3102 | URLs. Of course, you have to collect your modules somewhere first. So |
3103 | you might use CPAN.pm to put together all you need on a networked |
3104 | machine. Then copy the $CPAN::Config->{keep_source_where} (but not |
3105 | $CPAN::Config->{build_dir}) directory on a floppy. This floppy is kind |
3106 | of a personal CPAN. CPAN.pm on the non-networked machines works nicely |
3107 | with this floppy. |
10b2abe6 |
3108 | |
5f05dabc |
3109 | =head1 CONFIGURATION |
3110 | |
3111 | When the CPAN module is installed a site wide configuration file is |
3112 | created as CPAN/Config.pm. The default values defined there can be |
3113 | overridden in another configuration file: CPAN/MyConfig.pm. You can |
3114 | store this file in $HOME/.cpan/CPAN/MyConfig.pm if you want, because |
3115 | $HOME/.cpan is added to the search path of the CPAN module before the |
3116 | use() or require() statements. |
3117 | |
3118 | Currently the following keys in the hash reference $CPAN::Config are |
3119 | defined: |
3120 | |
42d3b621 |
3121 | build_cache size of cache for directories to build modules |
3122 | build_dir locally accessible directory to build modules |
3123 | index_expire after how many days refetch index files |
3124 | cpan_home local directory reserved for this package |
3125 | gzip location of external program gzip |
3126 | inactivity_timeout breaks interactive Makefile.PLs after that |
3127 | many seconds inactivity. Set to 0 to never break. |
5f05dabc |
3128 | inhibit_startup_message |
42d3b621 |
3129 | if true, does not print the startup message |
3130 | keep_source keep the source in a local directory? |
3131 | keep_source_where where keep the source (if we do) |
3132 | make location of external program make |
3133 | make_arg arguments that should always be passed to 'make' |
3134 | make_install_arg same as make_arg for 'make install' |
3135 | makepl_arg arguments passed to 'perl Makefile.PL' |
3136 | pager location of external program more (or any pager) |
3137 | tar location of external program tar |
3138 | unzip location of external program unzip |
3139 | urllist arrayref to nearby CPAN sites (or equivalent locations) |
5f05dabc |
3140 | |
3141 | You can set and query each of these options interactively in the cpan |
3142 | shell with the command set defined within the C<o conf> command: |
3143 | |
3144 | =over 2 |
3145 | |
3146 | =item o conf E<lt>scalar optionE<gt> |
3147 | |
3148 | prints the current value of the I<scalar option> |
3149 | |
3150 | =item o conf E<lt>scalar optionE<gt> E<lt>valueE<gt> |
3151 | |
3152 | Sets the value of the I<scalar option> to I<value> |
3153 | |
3154 | =item o conf E<lt>list optionE<gt> |
3155 | |
3156 | prints the current value of the I<list option> in MakeMaker's |
3157 | neatvalue format. |
3158 | |
3159 | =item o conf E<lt>list optionE<gt> [shift|pop] |
3160 | |
3161 | shifts or pops the array in the I<list option> variable |
3162 | |
3163 | =item o conf E<lt>list optionE<gt> [unshift|push|splice] E<lt>listE<gt> |
3164 | |
42d3b621 |
3165 | works like the corresponding perl commands. |
5f05dabc |

3167 | =back |
3168 | |
3169 | =head1 SECURITY |
3170 | |
3171 | There's no strong security layer in CPAN.pm. CPAN.pm helps you to |
3172 | install foreign, unmasked, unsigned code on your machine. We compare |
3173 | to a checksum that comes from the net just as the distribution file |
3174 | itself. If somebody has managed to tamper with the distribution file, |
3175 | they may have as well tampered with the CHECKSUMS file. Future |
42d3b621 |
3176 | development will go towards strong authentification. |
5f05dabc |
3177 | |
3178 | =head1 EXPORT |
3179 | |
3180 | Most functions in package CPAN are exported per default. The reason |
3181 | for this is that the primary use is intended for the cpan shell or for |
3182 | oneliners. |
3183 | |
da199366 |
3184 | =head1 BUGS |
5f05dabc |
3185 | |
da199366 |
3186 | we should give coverage for _all_ of the CPAN and not just the |
3187 | __PAUSE__ part, right? In this discussion CPAN and PAUSE have become |
3188 | equal -- but they are not. PAUSE is authors/ and modules/. CPAN is |
3189 | PAUSE plus the clpa/, doc/, misc/, ports/, src/, scripts/. |
5f05dabc |
3190 | |
da199366 |
3191 | Future development should be directed towards a better intergration of |
3192 | the other parts. |
