# JRuby Scripting
This add-on provides [JRuby](https://www.jruby.org/) scripting language for automation rules.
Also included is [openhab-scripting](https://openhab.github.io/openhab-jruby/), a fairly high-level Ruby gem to support automation in openHAB.
It provides native Ruby access to common openHAB functionality within rules including items, things, actions, logging and more.
This add-on provides Ruby scripting language for automation rules.
It includes the [openhab-scripting](https://openhab.github.io/openhab-jruby/) helper library, a comprehensive Ruby gem designed to enhance automation in openHAB.
This library offers a streamlined syntax for writing file-based and UI-based rules, making it easier and more intuitive than Rules DSL, while delivering the full features of the Ruby language.
If you're new to Ruby, you may want to check out [Ruby Basics](https://openhab.github.io/openhab-jruby/main/file.ruby-basics.html).
Example file-based rules:
```ruby
rule "Turn on light when sensor changed to open" do
changed Door_Sensor # a Contact item
run do |event|
if event.open?
Cupboard_Light.on for: 3.minutes # Automatically turn it off after 3 minutes
else
Cupboard_Light.off # This will automatically cancel the timer set above
end
end
end
```
```ruby
rule "Door open reminder" do
changed Doors.members, to: OPEN
run do |event|
# Create a timer using the triggering item as the timer id
# If a timer with the given id already exists, it will be rescheduled
after 5.minutes, id: event.item do |timer|
next if timer.cancelled? || event.item.closed?
Voice.say "The #{event.item} is open"
timer.reschedule # Use the original duration by default
end
end
end
```
Example UI-based rules:
```ruby
only_every(2.minutes) do # apply rate-limiting
Audio.play_sound("doorbell.mp3")
Notification.send("Someone pressed the doorbell")
end
```
Additional [example rules are available](https://openhab.github.io/openhab-jruby/main/file.examples.html), as well as examples of [conversions from Rules DSL, JavaScript, and Python rules](https://openhab.github.io/openhab-jruby/main/file.conversions.html).

## Why Ruby?
- Ruby is designed for programmers' productivity with the idea that programming should be fun for programmers.
- Ruby emphasizes the necessity for software to be understood by humans first and computers second.
- Ruby makes writing automation enjoyable without having to fight with compilers and interpreters.
- Rich ecosystem of tools, including things like Rubocop to help developers write clean code and RSpec to test the libraries.
- Ruby makes writing automation enjoyable with its readable syntax and a rich collection of useful methods in its built-in classes.
- Rich ecosystem of tools and libraries, including things like Rubocop to help developers write clean code and RSpec to test the libraries.
- Ruby is really good at letting one express intent and create a DSL to make that expression easier.

## Installation
### Prerequisites
1. openHAB 3.4+
1. The JRuby Scripting Language Addon
### From the User Interface
1. Go to `Settings -> Add-ons -> Automation` and install the jrubyscripting automation addon following the [openHAB instructions](https://www.openhab.org/docs/configuration/addons.html).
In openHAB 4.0+ the defaults are set so the next step can be skipped.
1. Go to `Settings -> Add-on Settings -> JRuby Scripting`:
- **Ruby Gems**: `openhab-scripting=~>5.0`
- **Require Scripts**: `openhab/dsl` (not required, but recommended)
- Go to `Settings -> Add-ons -> Automation` and install the jrubyscripting automation addon following the [openHAB instructions](https://www.openhab.org/docs/configuration/addons.html).
### Using Files
1. Edit `<OPENHAB_CONF>/services/addons.cfg` and ensure that `jrubyscripting` is included in an uncommented `automation=` list of automations to install.
In openHAB 4.0+ the defaults are set so the next step can be skipped.
1. Configure JRuby openHAB services
Create a file called `jruby.cfg` in `<OPENHAB_CONF>/services/` with the following content:
```ini
org.openhab.automation.jrubyscripting:gems=openhab-scripting=~>5.0
org.openhab.automation.jrubyscripting:require=openhab/dsl
```
- Edit `<OPENHAB_CONF>/services/addons.cfg` and ensure that `jrubyscripting` is included in an uncommented `automation=` list of automations to install.
## Configuration
After installing this add-on, you will find configuration options in the openHAB portal under _Settings -> Add-on Settings -> JRuby Scripting_.
Alternatively, JRuby configuration parameters may be set by creating a `jruby.cfg` file in `conf/services/`.
> **_NOTE:_**
> In openHAB 3.4.x, the `gems` and `require` settings must be manually configured to the value given in the table below.
Starting from openHAB 4.0, the correct defaults were added, so manual configurations are no longer necessary.
By default this add-on includes the [openhab-scripting](https://github.com/openhab/openhab-jruby) Ruby gem and automatically `require`s it.
This allows the use of [items](https://openhab.github.io/openhab-jruby/main/OpenHAB/DSL.html#items-class_method), [rules](https://openhab.github.io/openhab-jruby/main/OpenHAB/DSL.html#rules-class_method), [shared_cache](https://openhab.github.io/openhab-jruby/main/OpenHAB/DSL.html#shared_cache-class_method) and other objects in your scripts.
This functionality can be disabled for users who prefer to manage their own gems and `require`s via the add-on configuration options.
Simply change the `gems` and `require` configuration settings.
