The collections

Contents

Introduction

They are a lot of synonyms for defining a set of packages in the informatics jargon.

Under NuTyX, a set of packages is held in a collection.

A collection includes 3 fundamental properties:

  • Independent
  • Hierarchy
  • Interdepencies between them
Even if these properties could look contradictory, we will see in this tutorial why they are justified.

Definition

Under NuTyX, a collection is a set of recepts and binaries packages. This set provide certain functionalities. These functionalities are organised as follows:
  • Librairies and utilities for a base system
  • Librairies and utilities for a command line interface (cli)
  • Librairies and utilities for a graphical user interface (gui)
  • Extra librairies and utilities for a command line interface (cli-extra)
  • Extra librairies and utilities for a graphical user interface (gui-extra)
  • Graphicals interface
At the moment, all of following graphical interfaces are available as collections:
  • XFCE4
  • KDE5
  • MATE
  • LXDE
  • LXQT

Collections management via cards

Because of their concept, each collection contains it's own meta-data files. When adding / removing a package from a collection, only the meta-data files of this collection will need to be modified. This property offers maximum flexibility to the users and to the Package manager.

Collections hierachy

The hierachy of collections is an important concept.

Here the symbol "->" should be interpreted as "depends on"

Here is the fundamental rule:

desktops -> gui -> cli -> base

cli-extra -> cli -> base

gui-extra -> gui -> cli -> base

With this well established rule, the following concept is defined:

  • A package from the base collection can only use dependencies from the same base collection.
  • A package from the cli collection can only use dependencies from base or cli collections.
  • A package from the cli-extra collection can only use dependencies from base or cli collections.
  • A package from the gui collection can only use dependencies from base, cli or gui collections.
  • A package from the gui-extra collection can only use dependencies from base, cli or gui collections.
And for the graphical interfaces mate, kde5, lxde, lxqt, and xfce4, the concept is defined as follow:
  • A package from the desktops collection can only use dependencies from base, cli, gui or desktops collections.

Interdependencies

The NuTyX collections are interdependent in the following ways:
  • base: The base collection is the set of a minimum base system, it will always be needed. All the others collections depend on the base collection.
  • cli: The cli collection contains all the libraries and applications used by a command line interface.

    Only the base collection is a dependencie of the cli collection.

  • gui: The gui collection contains all the libraries and applications used by a graphical interface. The base and cli collections are dependencies of the gui collection.
  • cli-extra: The cli-extra collection contains applications used by a command line interface.

    The base and cli collections are the dependencies of the gui collection.

  • gui-extra: The gui-extra collection contains apllications used by a graphical interface.

    The base, cli and gui are the dependencies of the gui-extra collection.

  • desktops: The desktops contains all the available graphical interfaces available on NutyX.

    The base, cli and gui collections are the dependencies of the desktops collection.

The groups of collection

A. The base system collection

The collection consisting of the base system is:

  • base

B. The core system collections

The collections consisting of the core system are:

  • cli
  • gui

C. The Extra collections

The 'extra' collections are:

  • cli-extra
  • gui-extra

D. The graphical interfaces collection

The collection includes thoses graphical interfaces:

mate:

  • mate

kde5:

  • kde5

xfce4:

  • xfce4

lxqt:

  • lxqt

lxde:

  • lxde

And now ?

Collections have no more secrets for you. Now is the time to try to compile in an isolated chroot.
