Loaded / Unloaded Hooks

Method	Description
`script_loaded`	Add a block of code to be executed once the rule script has finished loading. This can occur on OpenHAB start up, when the script is first created, or updated.
`script_unloaded`	Add a block of code to be executed when the script is unloaded. This can occur when OpenHAB shuts down, or when the script is being reloaded.

Multiple hooks can be added by calling script_loaded / script_unloaded multiple times. They can be used to perform final initializations (script_loaded) and clean up (script_unloaded).

Note: All timers created with after are cancelled by the scripting library automatically when the script is unloaded/reloaded, so it is not necessary to cancel them.

Examples

script_loaded do
  logger.info 'Hi, this script has just finished loading'
end

script_loaded do
  logger.info 'I will be called after the script finished loading too'
end

script_unloaded do
  logger.info 'Hi, this script has been unloaded'
end

rule 'x' do
  changed Item1
  run { logger.info("Item1 changed") }
end
