Libyui is a widget abstraction library providing Qt, GTK and ncurses frontends. Originally it was developed for YaST but it can be used in any independent project.
This module provides the graphical (Qt) version of the YaST Package Selector which is used to update, install or delete individual packages.
An overview about package handling in general is available on the libyui-ncurses-pkg wiki page. The wiki page also describes common use cases and how to solve the task in YaST Software Management (for Qt as well as ncurses). Also included is the information about related configuration files.
For details about reported bugs and issues see the wiki page background.
Libyui uses CMake, driven by a slightly complex set of CMakefiles. For reproducible builds it is best to use the libyui-rake Ruby gem like the Jenkins CI jobs do.
It can be installed from rubygems.org using this command (Ruby needs to be installed in the system):
gem install libyui-rake
Then to build the package run:
rake osc:build
