Dpkg::Version – handling and comparing dpkg-style version numbers DescriptionThe Dpkg::Version module provides pure-Perl routines to compare dpkg-style version numbers (as used in Debian packages) and also an object oriented interface overriding perl operators to do the right thing when you compare Dpkg::Version object between them. Object Interfacemy $v = Dpkg::Version->new($version, %opts) Create a new Dpkg::Version…

Dpkg::Vendor::Ubuntu – Ubuntu vendor object DescriptionThis vendor object customize the behaviour of dpkg-source to check that Maintainers have been modified if necessary.

Returns all closed bug numbers in an array reference.ChangesVersion 0.xxThis is…

Dpkg::Vendor::Default – default vendor object DescriptionA vendor object is used to provide vendor specific behaviour in various places. This is the default object used in case there’s none for the current vendor or in case the vendor could not be identified (see Dpkg::Vendor documentation). It provides some hooks that are called by various dpkg-* tools….

Dpkg::Vendor::Debian – Debian vendor object DescriptionThis vendor object customize the behaviour of dpkg scripts for Debian specific actions. ChangesVersion 0.xxThis is a private module.

Dpkg::Vendor – get access to some vendor specific information DescriptionThe 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.orgIf the vendor derives from another vendor, the file should document the relationship by listing the base distribution in the…

Dpkg::Substvars – handle variable substitution in strings DescriptionIt provides some an object which is able to substitute variables in strings. Methodsmy $s = Dpkg::Substvars->new($file) Create a new object that can do substitutions. By default it contains generic substitutions like ${Newline}, ${Space}, ${Tab}, ${dpkg:Version} and ${dpkg:Upstream-Version}. Additional substitutions will be read from the $file passed as…

Dpkg::Source::Package – manipulate Debian source packages DescriptionThis module provides an object that can manipulate Debian source packages. While it supports both the extraction and the creation of source packages, the only API that is officially supported is the one that supports the extraction of the source package. Functionsmy $string = get_default_diff_ignore_regex() Returns the default diff…

Dpkg::Path – some common path handling functions DescriptionIt provides some functions to handle various path. Methodsget_pkg_root_dir($file) This function will scan upwards the hierarchy of directory to find out the directory which contains the “DEBIAN” sub-directory and it will return its path. This directory is the root directory of a package being built. If no DEBIAN…

Dpkg::Interface::Storable – common methods related to object serialization DescriptionDpkg::Interface::Storable is only meant to be used as parent class for other objects. It provides common methods that are all implemented on top of two basic methods parse() and output(). Base MethodsThose methods must be provided by the object that wish to inherit from Dpkg::Interface::Storable so that…

Dpkg::Index – generic index of control information DescriptionThis object represent a set of Dpkg::Control objects. Functionsmy $index = Dpkg::Index->new(%opts) Creates a new empty index. See set_options() for more details. $index->set_options(%opts) The “type” option is checked first to define default values for other options. Here are the relevant options: “get_key_func” is a function returning a key…

Dpkg::IPC – helper functions for IPC DescriptionDpkg::IPC offers helper functions to allow you to execute other programs in an easy, yet flexible way, while hiding all the gory details of IPC (Inter-Process Communication) from you. Methodsspawn Creates a child process and executes another program in it. The arguments are interpreted as a hash of options,…

Dpkg::Gettext – convenience wrapper around Locale::gettext DescriptionThe Dpkg::Gettext module is a convenience wrapper over the Locale::gettext module, to guarantee we always have working gettext functions, and to add some commonly used aliases. Functionsmy $trans = _g($msgid) Calls gettext() on the $msgid and returns its translation for the current locale. If gettext() is not available, simply…

Dpkg::Exit – program exit handlers DescriptionThe Dpkg::Exit module provides support functions to run handlers on exit. Functionspush_exit_handler($func) Register a code reference into the exit function handlers stack. pop_exit_handler() Pop the last registered exit handler from the handlers stack. run_exit_handlers() Run the registered exit handlers.ChangesVersion 1.01New functions: push_exit_handler(), pop_exit_handler(), run_exit_handlers() Deprecated variable: @handlers Version 1.00Mark the…

Dpkg::Deps – parse and manipulate dependencies of Debian packages DescriptionThe Dpkg::Deps module provides objects implementing various types of dependencies. The most important function is deps_parse(), it turns a dependency line in a set of Dpkg::Deps::{Simple,AND,OR,Union} objects depending on the case. FunctionsAll the deps_* functions are exported by default. deps_eval_implication($rel_p, $v_p, $rel_q, $v_q) ($rel_p, $v_p) and…

Dpkg::Control::Types – export CTRL_* constants DescriptionYou should not use this module directly. Instead you more likely want to use Dpkg::Control which also re-exports the same constants. This module has been introduced solely to avoid a dependency loop between Dpkg::Control and Dpkg::Control::Fields. ChangesVersion 0.xxThis is a private module. AuthorRaphaël Hertzog <hertzog [at] debian.org>.

Dpkg::Control::Info – parse files like debian/control DescriptionIt provides an object to access data of files that follow the same syntax as debian/control. Functions$c = Dpkg::Control::Info->new($file) Create a new Dpkg::Control::Info object for $file. If $file is omitted, it loads debian/control. If file is “-”, it parses the standard input. $c->reset() Resets what got read. $c->load($file) Load…

Dpkg::Control::HashCore – parse and manipulate a block of RFC822-like fields DescriptionThe Dpkg::Control::Hash object is a hash-like representation of a set of RFC822-like fields. The fields names are case insensitive and are always capitalized the same when output (see field_capitalize function in Dpkg::Control::Fields). The order in which fields have been set is remembered and is used…

Dpkg::Control::Hash – parse and manipulate a block of RFC822-like fields DescriptionThis module is just like Dpkg::Control::HashCore, with vendor-specific field knowledge. ChangesVersion 1.00Mark the module as public. AuthorRaphaël Hertzog <hertzog [at] debian.org>.

Dpkg::Control::FieldsCore – manage (list of official) control fields DescriptionThe modules contains a list of fieldnames with associated meta-data explaining in which type of control information they are allowed. The types are the CTRL_* constants exported by Dpkg::Control. Functionsmy $f = field_capitalize($field_name) Returns the field name properly capitalized.
