Overview

Description

Main goal of hooks is to execute a third party code within the workflow of installation, system update or some other process. Hook files must be executable files written in bash, ruby or anything else available in inst-sys environment.

The module provides method #run which creates a hook and executes it instantly.

This includes following actions: * adding the hook into the hooks collection - every hook is identified by unique name which should be self-descriptive * looking up the files matching the hook script pattern: hook_name[0-9]* * executing the identified hook files * storing the results returned by the scripts for further inspection later if needed; this might be useful if some of the files has failed and we want to show it the user.

If a hook script returns non-zero result, the whole hook is considered as failed. By default the hooks are searched for in /var/lib/YaST2/hooks directory. This path can be modified globally for all hooks before they get called.

Example

  • using a hook within a yast client

module Yast import 'Hooks'

class MyFavoriteClient < Client def main # this will change the search path to /var/lib/YaST2/hooks/personal Hooks.search_path.join!('personal') # and this will set a completely different path Hooks.search_path.set “/root/hooks” hook = Hooks.run 'before_showing_ui' # Lot of beautiful and useful code follows here. # If needed make use of: # * hook.failed? # * hook.succeeded? # * hook.name # * hook.results # * hook.files # * hook.search_path # * Hooks.last.failed? # * Hooks.last.succeeded? # * Hooks.last.name # * Hooks.last.search_path # * Hooks.last.results # * Hooks.last.files Hooks.run 'after_showing_ui' # reset the search path if needed Hooks.search_path.reset end end end
