41
42ProjectBuilder::Distribution, part of the project-builder.org - module dealing with distribution detection
43
44=head1 DESCRIPTION
45
46This modules provides functions to allow detection of Linux distributions, and giving back some attributes concerning them.

48=head1 SYNOPSIS

52 #
53 # Return information on the running distro
54 #
55 my $pbos = pb_distro_get_context();

57 #
58 # Return information on the requested distro
59 #
60 my $pbos = pb_distro_get_context("ubuntu-7.10-x86_64");
61 print "distro tuple: ".Dumper($pbos->name, $pbos->ver, $pbos->fam, $pbos->type, $pbos->pbsuf, $pbos->pbupd, $pbos->pbins, $pbos->arch)."\n";

69=over 4
70
71=item B<pb_distro_conffile>
72
73This function returns the mandatory configuration file used for distribution/OS detection
74
75=cut
76
77sub pb_distro_conffile {
78
79return("CCCC/pb.conf");
80}
81
82
83=item B<pb_distro_init>
84
85This function returns a hash of parameters indicating the distribution name, version, family, type of build system, suffix of packages, update command line, installation command line and architecture of the underlying Linux distribution. The value of the fields may be "unknown" in case the function was unable to recognize on which distribution it is running.
86
87As an example, Ubuntu and Debian are in the same "du" family. As well as RedHat, RHEL, CentOS, fedora are on the same "rh" family.
88Mandriva, Open SuSE and Fedora have all the same "rpm" type of build system. Ubuntu and Debian have the same "deb" type of build system.
89And "fc" is the extension generated for all Fedora packages (Version will be added by pb).
90All this information is stored in an external configuration file typically at /etc/pb/pb.conf
91
92When passing the distribution name and version as parameters, the B<pb_distro_init> function returns the parameter of that distribution instead of the underlying one.
