NAME
Dpkg::Vendor - get access to some vendor specific information
DESCRIPTION
The files in $Dpkg::CONFDIR/origins/ can provide information about
various vendors who are providing Debian packages. Currently those
files look like this:
Vendor: Debian
Vendor-URL: https://www.debian.org/
Bugs: debbugs://bugs.debian.org
If the vendor derives from another vendor, the file should document the
relationship by listing the base distribution in the Parent field:
Parent: Debian
The file should be named according to the vendor name. The usual
convention is to name the vendor file using the vendor name in all
lowercase, but some variation is permitted. Namely, spaces are mapped
to dashes ('-'), and the file can have the same casing as the Vendor
field, or it can be capitalized.
FUNCTIONS
$dir = get_vendor_dir()
Returns the current dpkg origins directory name, where the vendor
files are stored.
$fields = get_vendor_info($name)
Returns a Dpkg::Control object with the information parsed from the
corresponding vendor file in $Dpkg::CONFDIR/origins/. If $name is
omitted, it will use $Dpkg::CONFDIR/origins/default which is
supposed to be a symlink to the vendor of the currently installed
operating system. Returns undef if there's no file for the given
vendor.
$name = get_vendor_file($name)
Check if there's a file for the given vendor and returns its name.
The vendor filename will be derived from the vendor name, by
replacing any number of non-alphanumeric characters (that is
[^A-Za-z0-9]) into "-", then the resulting name will be tried in
sequence by lower-casing it, keeping it as is, lower-casing then
capitalizing it, and capitalizing it.
In addition, for historical and backwards compatibility, the name
will be tried keeping it as is without non-alphanumeric characters
remapping, then the resulting name will be tried in sequence by
lower-casing it, keeping it as is, lower-casing then capitalizing
it, and capitalizing it. And finally the name will be tried by
replacing only spaces to "-", then the resulting name will be tried
in sequence by lower-casing it, keeping it as is, lower-casing then
capitalizing it, and capitalizing it.
But these backwards compatible name lookups will be removed during
the dpkg 1.22.x release cycle.
$name = get_current_vendor()
Returns the name of the current vendor. If DEB_VENDOR is set, it
uses that first, otherwise it falls back to parsing
$Dpkg::CONFDIR/origins/default. If that file doesn't exist, it
returns undef.
$object = get_vendor_object($name)
Return the Dpkg::Vendor::* object of the corresponding vendor. If
$name is omitted, return the object of the current vendor. If no
vendor can be identified, then return the Dpkg::Vendor::Default
object.
The module name will be derived from the vendor name, by splitting
parts around groups of non alphanumeric character (that is
[^A-Za-z0-9]) separators, by either capitalizing or lower-casing
and capitalizing each part and then joining them without the
separators. So the expected casing is based on the one from the
Vendor field in the origins file.
In addition, for historical and backwards compatibility, the module
name will also be looked up without non-alphanumeric character
stripping, by capitalizing, lower-casing then capitalizing, as-is
or lower-casing. But these name lookups will be removed during the
1.22.x release cycle.
run_vendor_hook($hookid, @params)
Run a hook implemented by the current vendor object.
