24 | =head1 NAME
|
---|
25 |
|
---|
26 | ProjectBuilder::Distribution, part of the project-builder.org - module dealing with distribution detection
|
---|
27 |
|
---|
28 | =head1 DESCRIPTION
|
---|
29 |
|
---|
30 | This modules provides functions to allow detection of Linux distributions, and giving back some attributes concerning them.
|
---|
31 |
|
---|
32 | =head1 SYNOPSIS
|
---|
33 |
|
---|
34 | use ProjectBuilder::Distribution;
|
---|
35 |
|
---|
36 | #
|
---|
37 | # Return information on the running distro
|
---|
38 | #
|
---|
39 | my ($ddir, $dver, $dfam, $dtype, $pbsuf) = pb_distro_init();
|
---|
40 | print "distro tuple: ".Dumper($ddir, $dver, $dfam, $dtype, $pbsuf)."\n";
|
---|
41 | #
|
---|
42 | # Return information on the requested distro
|
---|
43 | #
|
---|
44 | my ($ddir, $dver, $dfam, $dtype, $pbsuf) = pb_distro_init("ubuntu","7.10");
|
---|
45 | print "distro tuple: ".Dumper($ddir, $dver, $dfam, $dtype, $pbsuf)."\n";
|
---|
46 | #
|
---|
47 | # Return information on the running distro
|
---|
48 | #
|
---|
49 | my ($ddir,$dver) = pb_get_distro();
|
---|
50 | my ($ddir, $dver, $dfam, $dtype, $pbsuf) = pb_distro_init($ddir,$dver);
|
---|
51 | print "distro tuple: ".Dumper($ddir, $dver, $dfam, $dtype, $pbsuf)."\n";

53 | =head1 USAGE
|
---|
54 |
|
---|
55 | =over 4
|
---|
56 |
|
---|
57 | =item B<pb_get_distro>
|
---|
58 |
|
---|
59 | This function returns a list of 2 parameters indicating the distribution name and version of the underlying Linux distribution. The value of those 2 fields may be "unknown" in case the function was unable to recognize on which distribution it is running.
|
---|
60 |
|
---|
61 | On my home machine it would currently report ("mandriva","2008.0").
|
---|
62 |
|
---|
63 | =item B<pb_distro_init>
|
---|
64 |
|
---|
65 | This function returns a list of 5 parameters indicating the distribution name, version, family, type of build system and suffix of packages of the underlying Linux distribution. The value of the 5 fields may be "unknown" in case the function was unable to recognize on which distribution it is running.
|
---|
66 |
|
---|
67 | As an example, Ubuntu and Debian are in the same "du" family. As well as RedHat, RHEL, CentOS, fedora are on the same "rh" family.
|
---|
68 | Mandriva, Open SuSE and Fedora have all the same "rpm" type of build system. Ubuntu ad Debian have the same "deb" type of build system.
|
---|
69 | And "fc" is the extension generated for all Fedora packages (Version will be added by pb).
|
---|
70 |
|
---|
71 | When 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.
