NAME cpan2rpm - A Perl module packager SYNOPSIS cpan2rpm [options] <module> DESCRIPTION This script will generate an RPM package from a Perl module. It uses the standard RPM file structure and creates a spec file, a source RPM, and a binary, leaving these in their respective directories. The directory structure used follows the definition rules RPM uses whereby /usr/lib/rpm/macros is used by default but may be overridden by macros in /etc/rpm/macros and ~/.rpmmacrocs in that order. If the <module> passed is either a CPAN module name (e.g. XML::Simple) or a URL (both http:// and ftp:// style locators will work) the script automatically downloads the given module (when CPAN module names are specified, the latest distribution is used), putting it in the SOURCES directory. If <module> is a local filename reference (e.g. /tmp/XML-Simple-1.05.tar.gz), the tarball gets copied to the SOURCES directory. Headers in the spec will generally assume any values configured in the RPM macro files as described above. Use of any particular option will override the internally calculated or configured values. Whenever a header is neither configured in the RPM macro files nor is passed at the command line, the script will seek to calculate a proper value and supplies a default as stated for each option below. It is thus typicall sufficient to provide only the <module>. The `options' available are as follows: *--pkgname=`string-value'* The RPM package name. This is the `Name' header in the RPM's spec file. Please note that the string `perl-' will be prepended to any value passed here. If no value is supplied, the script will use the NAME field found in the module's Makefile.PL *--version=`float-value'* The script determines the version number of the module by parsing the tarball name. *--release=`integer-value'* The package release number. Defaults to 1. *--summary=`string-value'* A one-line description of the package. If left unspecified the script will use the module name, appending an abstract whenever available. *--description=`string-value'* This text describes the package/module. This value is picked up from the POD in the module. Defaults to "None.". *--url=`string-value'* The home url for the package. Defaults to http://www.cpan.org. *--group=`string-value'* This is the RPM group. For further information on available groups please see your RPM documentation. Defaults to `Applications/CPAN'. *--author=`string-value'* This is the name and address of the person who authored the module. Typically it should be in the format: *Name <e-mail-address>*. If left unspecified, the script will attempt to extract it from the tarball's MakeMaker file, failing to build the package otherwise. There is no default for this option. *--packager=`string-value'* This is you (if you're packaging someone else's module). The string should be in the same format as for --author and defaults to: `Arix International <cpan2rpm@arix.com>' unless the RPM macro files provide a value. *--license=`string-value'* The license header specified in the spec file. This field is also sometimes referred to as *Copyright*, but *License* is a more suitable name and has become more common. Defaults to `Artistic', Perl's own license. *--distribution=`string-value'* The script will use the %{distribution} tag defined in the RPM macros file. If this tag is not set, the script will attempt to determine the distribution name by looking at the /etc/issue file. If this file does not exist, the distribution will be left blank. *--buildarch=`string-value'* Allows specification of an architecture for building the RPM. Currently defaults to `i386'. *--buildroot=`string-value'* Allows specifying a directory to use as a BuildRoot. Don't mess with this is you don't know what it is. Defaults to: `%{_tmppath}/%{name}-%{version}'. *--provides=`string-value'* Indicates that a package should be provided by the module being built. RPM will generate an appropriate list of provided dependencies and any passed here will be *in addition* to those calculated. *--requires=`string-value'* Indicates packages that should be required for installation. This option works precisely as --requires above. *--no-requires=`string-value'* Suppresses generation of a given required dependency. Sometimes authors create dependencies on modules the packager can't find, sometimes RPM generates spurious dependencies. This option allows the packager to arbitrarily supress a given requirement. The value may be a comma-separated list. *--spec-only* This option instructs the script to not build the RPM package but instead to oly display the generated spec file on stdout. *--make-maker=`string-value'* This option allows passing a string to the MakeMaker process (i.e. perl Makefile.PL <your-arguments-here>) *--nopkgprfx* Suppresses prefixing the package name with the string `perl-'. *--force* By default the script will do as little work as possible i.e. if it has alreaddy previously retrieved a module from CPAN, it will not retrieve it again. If it has already generated a spec file it will not generate it again. This option allows the packager to force all actions, starting from scratch. *--debug[=n]* This option produces debugging output. An optional integer increases the level of verbosity for this output. If no integer is given, 1 is assumed. *--help, -h* Displays a terse syntax message. NOTES This script requires that RPM be installed. Both rpm and rpm-build must be installed on the local machine. Please see the RPM documentation (man rpm) for further information. Additionally, the Perl module will be needed :) and the CPAN module (which is bundled with the Perl distribution) will need to be configured. For further information please refer to the CPAN manpage. TODO I'm happy to work on any feature requests you may send me :) but in the meantime these are the things waiting for attention: BUGS Same goes for bugs.

Revision 1.5 2002/05/23 02:55:37 ekkis adding "use strict" forces Makefile.PL to be eval()uated that way so had to add "no strict" to eval string. Also added warning in case eval fails. Revision 1.4 2002/05/23 02:43:43 ekkis added use strict Revision 1.3 2002/05/23 02:14:04 ekkis oops, small patch Revision 1.2 2002/05/23 02:13:07 ekkis added --nopkgprfx in case we want to build RPMs without a prepended "perl-" (as in the case of cpan2rpm<g>) Revision 1.1 2002/05/22 23:47:59 ekkis Moved from dist to . Revision 1.40 2002/05/22 23:03:35 ekkis since we're no longer including the package version number in the spec filename when building multiple versions of the same package we're force to --force. this makes no sense to the script will now _always_ build the spec file Revision 1.39 2002/05/19 01:04:44 ekkis still haveing problem with DBI - couldn't figure out how to eval() Makefile.PL so assuming pkgname from module (or passed) Revision 1.38 2002/05/18 22:55:00 ekkis - patched to allow calls like "use ExtUtils::MakeMaker qw(WriteMakefile)"... note this currently only works with () and will fail with qw//. Due to DBI calls. - also changed MyExit() to die() instead since we really do need for the script to exit but without exiting us! - patched to allow for calls like ExtUtils::MakeMaker::WriteMakefile() as found in DBD::mysql Revision 1.37 2002/05/07 04:21:49 ekkis added --make-maker parameter Revision 1.36 2002/04/23 00:29:24 ekkis - implemented protection of my variables from Makefile.PL being eval()d by surrounding that code with a package. Considered the Safe module but decided against another dependency. Revision 1.35 2002/04/22 23:19:13 ekkis --provides and --requires weren't working Revision 1.34 2002/04/18 08:32:53 ekkis - put back code to generate name/e-mail addr of packager (uses hostname()) - added END {} code to make sure we clean up. $SIG{__DIE__} works only for die() calls - now picks up AUTHOR from tarball POD when possible - modified version parsing code to allow versions with alpha - redesigned tarls(). now context sensitive, much better way to determine embedded directory - writefile() now checks for existence Revision 1.33 2002/04/17 08:52:43 ekkis - some bug fixes - {force} implementation for get_url() Revision 1.32 2002/04/17 08:40:50 ekkis - added --no-requires, --find-provides, --find-requires and --install options - now can receive a URL to download from - reimplemented MyExit for eval()ing Makefile.PL - enhancements to writefile() Revision 1.31 2002/04/16 04:06:53 ekkis ripped out all dependency (provides,requires) generation code as the newer rpm-buid generates this correctly Revision 1.30 2002/04/12 17:22:35 ekkis - filelist is now abstracted - cool new method for extracting CVS version without breaking emacs - new regexp for splitting path/filename from given $info{module} Revision 1.29 2002/04/09 23:00:16 ekkis took out %define version and release as it causes recursive behaviour Revision 1.28 2002/04/09 22:20:41 ekkis - better relative path handling - now prepends url to Source: field when available via CPAN - BuildRoot more automated now Revision 1.27 2002/04/09 08:25:00 ekkis - now requires version 0.59 or greater of CPAN as previous versions are problema tic - implemented use of RPM macros to figure outdirectory structures. script now p arses the various macro definition files and does recursive expansions to figure out correct values... see docs. - added support for a full-path tarball specification. this allows the user to call cpan2rpm with any tarball anywhere. The tarball will be copied to SOURCES. - defined %version, %release - added Rob Brown's perlver %defines - BuildRoot now defaults to the standard %{_tmpdir} - removed version number from spec filename - now scans only usr/lib in tmpdir for modules (should give better Provides headers since we don't pick up .pm files in other directories like examples/) - added code to figure out real module dependencies (PREREQ_PM is unreliable) - now attempts to read VERSION_FROM if neither ABSTRACT nor ABSTRACT_FROM is provided. failing that it will take the module name (minus any parent info, plus appropriate extension e.g. Ping.pm from Net::Ping), and if that file exists will scan it for POD Revision 1.26 2002/04/08 22:30:35 ekkis now requires CPAN version 0.59 as previous versions seem broken added to TODO list Revision 1.25 2002/04/07 09:18:19 ekkis hijacked exit() for the Makefile.PL eval since certain modules exit on us (not very exciting) e.g. POE Revision 1.24 2002/04/07 02:31:00 ekkis fixed generation of dependencies on Perl core modules (not allowed) Revision 1.23 2002/04/07 01:15:33 ekkis removed dashed lines from CHANGES section... don't konw thy CVS does use this in keyword expansion! Revision 1.22 2002/04/07 01:12:24 ekkis added old Log info Revision 1.21 2002/04/07 01:09:01 ekkis tarball maker now calls system() instead of qx// so user can see prompts added CHANGES section revision 1.20 date: 2002/04/07 00:06:20; author: ekkis; state: Exp; lines: +4 -1 added back author info retrieval from CPAN when possible revision 1.19 date: 2002/04/06 23:45:25; author: ekkis; state: Exp; lines: +4 -2 added availability section to pod revision 1.18 date: 2002/04/06 23:43:00; author: ekkis; state: Exp; lines: +6 -8 changed default for license to "Artistic" as most modules are released under Perl's own license. revision 1.17 date: 2002/04/06 23:13:31; author: ekkis; state: Exp; lines: +2 -2 removed spaces before =head1 NAME - he cares!! revision 1.16 date: 2002/04/06 23:03:28; author: ekkis; state: Exp; lines: +2 -2 a fix for a fix revision 1.15 date: 2002/04/06 22:51:36; author: ekkis; state: Exp; lines: +2 -2 fixed docs revision 1.14 date: 2002/04/06 22:47:40; author: ekkis; state: Exp; lines: +33 -19 added --debug added -n in calls to silence questions from Makefile.PL (may not always work) now makes sure /tmp/cpan2rpm exists, creates as needed revision 1.13 date: 2002/04/06 02:34:15; author: ekkis; state: Exp; lines: +18 -1 status info revision 1.12 date: 2002/04/06 01:57:31; author: ekkis; state: Exp; lines: +8 -5 enhancement for f2mod() to generate RPM dependencies revision 1.11 date: 2002/04/06 01:51:22; author: ekkis; state: Exp; lines: +71 -68 various fixes incorporated provides() into get_meta() correctly generates Provides header revision 1.10 date: 2002/04/06 00:01:15; author: ekkis; state: Exp; lines: +55 -22 added f2mod() enhancements to untar() now generates Provides headers revision 1.9 date: 2002/04/05 22:37:05; author: ekkis; state: Exp; lines: +167 -102 major code reorg now uses ExtUtils::Installed for platform independent module listings added --provides and --spec-only revision 1.8 date: 2002/04/05 05:29:57; author: ekkis; state: Exp; lines: +2 -2 fixed regexp for tardir revision 1.7 date: 2002/04/05 02:07:25; author: ekkis; state: Exp; lines: +33 -20 now eval()s Makefile.PL instead of parsing it also looks up DESCRIPTION from module file for spec file revision 1.6 date: 2002/04/04 03:55:27; author: ekkis; state: Exp; lines: +2 -2 fixed embedded >s in tags revision 1.5 date: 2002/04/04 03:47:34; author: ekkis; state: Exp; lines: +15 -5 added author support revision 1.4 date: 2002/04/04 02:20:32; author: ekkis; state: Exp; lines: +105 -83 general cleanup now excepts core Perl modules from RPM dependencies now supports ABSTRACT_FROM improved PREREQ_PM handling (with Provides: clause) revision 1.3 date: 2002/04/03 12:33:14; author: ekkis; state: Exp; lines: +38 -18 various bug fixes revision 1.2 date: 2002/04/03 11:08:32; author: ekkis; state: Exp; lines: +144 -142 now retrieves metadata from tarball revision 1.1 date: 2002/04/03 10:57:00; author: ekkis; state: Exp; branches: 1.1.1; Initial revision revision 1.1.1.1 date: 2002/04/03 10:57:00; author: ekkis; state: Exp; lines: +0 -0 Initial import
