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.
