debtools 0.3

Utilities for creating mutliple Debian packages.

DebTools
========

`deb-dep-tree`
--------------

Download packages and show the dependencies of a given package:

$ deb-dep-tree libgcc1_4.7.2-5_amd64.deb
libgcc1
=======

* multiarch-support
* gcc-4.7-base (= 4.7.2-5)
* libc6 (>= 2.2.5)

Ok, nothing new from the standard `dpkg -I libgcc1_4.7.2-5_amd64.deb` command, but you can provide either a package name or a .deb filename:

$ deb-dep-tree libgcc1
Réception de : 1 Téléchargement de libgcc1 1:4.7.2-5 [43,1 kB]
43,1 ko réceptionnés en 0s (45,2 ko/s)
libgcc1
=======

* multiarch-support
* gcc-4.7-base (= 4.7.2-5)
* libc6 (>= 2.2.5)

The package will be downloaded in the current directory. You can recursively retrieve all dependencies.

$ deb-dep-tree libgcc1 -r
libgcc1
=======

* multiarch-support
* gcc-4.7-base (= 4.7.2-5)
* libc6 (>= 2.2.5)

multiarch-support
=================

* libc6 (>= 2.3.6-2)

libc-bin
========


gcc-4.7-base
============


libc6
=====

* libc-bin (= 2.13-38+deb7u8)
* libgcc1

$ ls
gcc-4.7-base_4.7.2-5_amd64.deb libc6_2.13-38+deb7u8_amd64.deb libc-bin_2.13-38+deb7u8_amd64.deb libgcc1_4.7.2-5_amd64.deb multiarch-support_2.13-38+deb7u8_amd64.deb



Sometimes, there is a choice between several possibilities for a given dependency. These dependencies are ignored (since we cannot select one).
However, you can use the `-l` flag to select choices which are currently installed on the system.

$ dpkg -I libssl1.0.0_1.0.1e-2+deb7u17_amd64.deb | grep Depends
Pre-Depends: multiarch-support
Depends: libc6 (>= 2.7), zlib1g (>= 1:1.1.4), debconf (>= 0.5) | debconf-2.0

$ dpkg -l | grep debconf
ii debconf 1.5.49 all Debian configuration management system
ii debconf-i18n 1.5.49 all full internationalization support for debconf
ii po-debconf 1.0.16+nmu2 all tool for managing templates file translations with gettext

$ deb-dep-tree libssl1.0.0
libssl1.0.0
===========

* multiarch-support
* zlib1g (>= 1:1.1.4)
* libc6 (>= 2.7)

$ deb-dep-tree libssl1.0.0 -l
libssl1.0.0
===========

* debconf
* multiarch-support
* zlib1g (>= 1:1.1.4)
* libc6 (>= 2.7)

You can also ignore some dependencies, by providing a file with a list of dependencies to ignore. Its format is the same as the output of the `dpkg -l` command.

$ dpkg -l | grep libc > /tmp/toignore
$ deb-dep-tree libgcc1 -r -i /tmp/toignore
libgcc1
=======

* multiarch-support
* gcc-4.7-base (= 4.7.2-5)
* libc6 (>= 2.2.5)

multiarch-support
=================

* libc6 (>= 2.3.6-2)

gcc-4.7-base
