NAME

       AptPkg::Source - APT source package interface

SYNOPSIS

       use AptPkg::Source;

DESCRIPTION

       The AptPkg::Source module provides an interface to APT's source package lists.

   AptPkg::Source
       The AptPkg::Source package implements the APT pkgSrcRecords class as a hash reference (inherits from
       AptPkg::hash).  The hash is keyed on source or binary package name and the value is an array reference of
       the details of matching source packages.

       Note that there is no iterator class, so it is not possible to get a list of all keys (with keys or
       each).

       Constructor

       new([SOURCELIST])
           Instantiation   of   the   object   uses   configuration  from  the  $AptPkg::Config::_config  object
           (automatically initialised if not done explicitly).

           If no SOURCELIST is specified, then the value of Dir::Etc::sourcelist from the  configuration  object
           is used (generally /etc/apt/sources.list).

       Methods

       find(PACK, [SRCONLY])
           In  a list context, return a list of source package details for the given PACK, which may either be a
           source package name, or the name of one of the binaries provided  (unless  SRCONLY  is  provided  and
           true).

           In a scalar context, the source package name of the first entry is returned.

       get, exists
           These  methods  are used to implement the hashref abstraction: $obj->get($pack) and $obj->{$pack} are
           equivalent.

           The get method has the same semantics as find, but returns an array reference in a scalar context.

       The list returned by the find (and get) methods consists of hashes which describe each  available  source
       package (in order of discovery from the deb-src files described in sources.list).

       Each hash contains the following entries:

       Package
       Version
       Maintainer
       Section
           Strings giving the source package name, version, maintainer and section.

       AsStr
           The  full source record as a string in Debian control file syntax <https://www.debian.org/doc/debian-
           policy/ch-controlfields.html#s-controlsyntax>, which is an RFC822-like set of  key-value  pairs  with
           the values potentially wrapped.  It is relatively trivial to parse:

             my %fields = map { split /:\s+/ } split /\n(?! )/, $as_str;

       Binaries
           A list of binary package names from the package.

       BuildDepends
           A hash describing the build dependencies of the package.  Possible keys are:

               "Build-Depends", "Build-Depends-Indep", "Build-Conflicts", "Build-Conflicts-Indep".

           The  values  are  a list of dependencies/conflicts with each item being a list containing the package
           name followed optionally by an operator and version number.

           Operator values evaluate to a comparison string* (>, >=, etc) or one of the  AptPkg::Dep::  constants
           in a numeric context (see "pkgCache::Dep::DepCompareOp" in AptPkg(3pm)).

           *Note that this is a normalised, rather than Debian-style (>> vs >) string.

       Files
           A list of files making up the source package, each described by a hash containing the keys:

               "Checksum-FileSize", "MD5Hash", "SHA256", "Size", "ArchiveURI", "Type".
