6 Dpkg::Vendor - get access to some vendor specific information
7
9 The files in $Dpkg::CONFDIR/origins/ can provide information about
10 various vendors who are providing Debian packages. Currently those
11 files look like this:
12 Vendor: Debian
14 Vendor-URL: https://www.debian.org/
15 Bugs: debbugs://bugs.debian.org
16 If the vendor derives from another vendor, the file should document the
18 relationship by listing the base distribution in the Parent field:
19 Parent: Debian
21 The file should be named according to the vendor name. The usual
23 convention is to name the vendor file using the vendor name in all
24 lowercase, but some variation is permitted. Namely, spaces are mapped
25 to dashes ('-'), and the file can have the same casing as the Vendor
26 field, or it can be capitalized.
27
29 $dir = get_vendor_dir()
30 Returns the current dpkg origins directory name, where the vendor
31 files are stored.
32 $fields = get_vendor_info($name)
34 Returns a Dpkg::Control object with the information parsed from the
35 corresponding vendor file in $Dpkg::CONFDIR/origins/. If $name is
36 omitted, it will use $Dpkg::CONFDIR/origins/default which is
37 supposed to be a symlink to the vendor of the currently installed
38 operating system. Returns undef if there's no file for the given
39 vendor.
40 $name = get_vendor_file($name)
42 Check if there's a file for the given vendor and returns its name.
43 The vendor filename will be derived from the vendor name, by
45 replacing any number of non-alphanumeric characters (that is
46 [^A-Za-z0-9]) into "-", then the resulting name will be tried in
47 sequence by lower-casing it, keeping it as is, lower-casing then
48 capitalizing it, and capitalizing it.
49 In addition, for historical and backwards compatibility, the name
51 will be tried keeping it as is without non-alphanumeric characters
52 remapping, then the resulting name will be tried in sequence by
53 lower-casing it, keeping it as is, lower-casing then capitalizing
54 it, and capitalizing it. And finally the name will be tried by
55 replacing only spaces to "-", then the resulting name will be tried
56 in sequence by lower-casing it, keeping it as is, lower-casing then
57 capitalizing it, and capitalizing it.
58 But these backwards compatible name lookups will be removed during
60 the dpkg 1.22.x release cycle.
61 $name = get_current_vendor()
63 Returns the name of the current vendor. If DEB_VENDOR is set, it
64 uses that first, otherwise it falls back to parsing
65 $Dpkg::CONFDIR/origins/default. If that file doesn't exist, it
66 returns undef.
67 $object = get_vendor_object($name)
69 Return the Dpkg::Vendor::* object of the corresponding vendor. If
70 $name is omitted, return the object of the current vendor. If no
71 vendor can be identified, then return the Dpkg::Vendor::Default
72 object.
73 The module name will be derived from the vendor name, by splitting
75 parts around groups of non alphanumeric character (that is
76 [^A-Za-z0-9]) separators, by either capitalizing or lower-casing
77 and capitalizing each part and then joining them without the
78 separators. So the expected casing is based on the one from the
79 Vendor field in the origins file.
80 In addition, for historical and backwards compatibility, the module
82 name will also be looked up without non-alphanumeric character
83 stripping, by capitalizing, lower-casing then capitalizing, as-is
84 or lower-casing. But these name lookups will be removed during the
85 1.22.x release cycle.
86 run_vendor_hook($hookid, @params)
88 Run a hook implemented by the current vendor object.

93 special characters remapping. get_vendor_object() loading vendor module
94 names with no special character stripping.
95 Version 1.01 (dpkg 1.17.0)
97 New function: get_vendor_dir().
