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".
