[GLIMMER VIDEO TUTORIAL CHANNEL](https://www.youtube.com/channel/UC5hzDE23HZXsZLAxYk2UJEw)
[Glimmer](https://github.com/AndyObtiva/glimmer) DSL for [SWT](https://www.eclipse.org/swt/) (formerly [Glimmer](https://github.com/AndyObtiva/glimmer)) is a native GUI (Graphical User Interface) cross-platform desktop development library written in [JRuby](https://www.jruby.org/), an OS-threaded faster [JVM](https://www.java.com/en/download/help/whatis_java.html) version of [Ruby](https://www.ruby-lang.org/en/). [Glimmer](https://github.com/AndyObtiva/glimmer)'s main innovation is a minimalistic declarative [Ruby DSL](docs/reference/GLIMMER_GUI_DSL_SYNTAX.md#glimmer-dsl-syntax) (Domain Specific Language) that enables productive and efficient authoring of professional-grade desktop applications by relying on the robust [Eclipse SWT library](https://www.eclipse.org/swt/), with the familiar native look, feel, and behavior of GUI on Mac, Windows, and Linux. [Glimmer](https://rubygems.org/gems/glimmer) additionally innovates by having built-in [data-binding](docs/reference/GLIMMER_GUI_DSL_SYNTAX.md#data-binding) support, which greatly facilitates synchronizing the GUI with domain models, thus achieving true decoupling of object oriented components and enabling developers to solve business problems (test-first) without worrying about GUI concerns, or alternatively drive development GUI-first, and then write clean business models afterwards. Not only does Glimmer provide a large set of GUI [widgets](docs/reference/GLIMMER_GUI_DSL_SYNTAX.md#widgets), but it also supports drawing Canvas Graphics like [Shapes](docs/reference/GLIMMER_GUI_DSL_SYNTAX.md#canvas-shape-dsl) and [Animations](docs/reference/GLIMMER_GUI_DSL_SYNTAX.md#canvas-animation-dsl). To get started quickly, [Glimmer](https://rubygems.org/gems/glimmer) offers [scaffolding](docs/reference/GLIMMER_COMMAND.md#scaffolding) options for [Apps](#in-production), [Gems](docs/reference/GLIMMER_COMMAND.md#custom-shell-gem), and [Custom Widgets](docs/reference/GLIMMER_GUI_DSL_SYNTAX.md#custom-widgets). [Glimmer](https://rubygems.org/gems/glimmer) also includes native-executable [packaging](docs/reference/GLIMMER_PACKAGING_AND_DISTRIBUTION.md) support, sorely lacking in other libraries, thus enabling the delivery of desktop apps written in [Ruby](https://www.ruby-lang.org/en/) as truly native DMG/PKG/APP files on the [Mac](https://www.apple.com/ca/macos), MSI/EXE files on [Windows](https://www.microsoft.com/en-ca/windows), and DEB/RPM files on [Linux](https://www.linux.org/). [Glimmer](https://github.com/AndyObtiva/glimmer) was the [first Ruby gem](https://rubygems.org/gems/glimmer) to bring [SWT](https://www.eclipse.org/swt/) (Standard Widget Toolkit) to [Ruby](https://www.ruby-lang.org/en/), thanks to creator [Andy Maleh](https://andymaleh.blogspot.com/), EclipseCon/EclipseWorld/RubyConf speaker.
[
Featured in JRuby Cookbook](http://shop.oreilly.com/product/9780596519650.do) and [Chalmers/Gothenburg University Software Engineering Master's Lecture Material](http://www.cse.chalmers.se/~bergert/slides/guest_lecture_DSLs.pdf)
[SWT](https://www.eclipse.org/swt/) (Standard Widget Toolkit) is a very robust GUI toolkit that is most famous for building the [Eclipse IDE](https://www.eclipse.org/ide/), a free and open-source general language Integrated Development Environment that was the first to provide a high-performance pause-free [Java](https://www.oracle.com/ca-en/java/) IDE (unlike earlier versions of NetBeans and other [Java](https://www.oracle.com/ca-en/java/) IDEs), thanks to its very smart software architecture. Additionally, [Eclipse RCP (Rich Client Platform, built on top of SWT) has been used by NASA to build Mars Rover operational software](https://www.eclipse.org/community/casestudies/NASAfinal.pdf). So, [Eclipse technologies](https://www.eclipse.org/) are not only very highly proven, but are also considered some of the best in the world.
[Glimmer DSL for SWT](https://rubygems.org/gems/glimmer-dsl-swt) 4.30.0.0 includes [SWT 4.30](https://download.eclipse.org/eclipse/downloads/drops4/R-4.30-202312010110/), which was released on December 1, 2023. Gem version numbers are in sync with the SWT library versions. The first two digits represent the SWT version number. The last two digits represent the minor and patch versions of Glimmer DSL for SWT. Note that SWT supports ARM64/AARCH64 on Mac and Linux since version `4.20`.
**Starting in version 4.20.0.0, [Glimmer DSL for SWT](https://rubygems.org/gems/glimmer-dsl-swt) comes with the new [***Shine***](/docs/reference/GLIMMER_GUI_DSL_SYNTAX.md#shine) syntax** for highly intuitive and visually expressive View/Model Attribute Mapping, relying on `<=>` for bidirectional (two-way) data-binding and `<=` for unidirectional (one-way) data-binding, providing an alternative to the `bind` keyword. That was [originally conceived back in 2007](https://andymaleh.blogspot.com/2007/12/data-shining-in-glimmer.html).
Please help make [Glimmer DSL for SWT](https://rubygems.org/gems/glimmer-dsl-swt) better by providing feedback and [contributing](#contributing) whenever possible. Any feature suggestions that are accepted could be implemented within weeks if not days.
This is a [JRuby](https://www.jruby.org/) desktop GUI library.

## Background
[Ruby](https://www.ruby-lang.org) is a dynamically-typed object-oriented language, which provides great productivity gains due to its expressive syntax and dynamic nature. While it is proven by the [Ruby](https://www.ruby-lang.org) on Rails framework for web development, it currently lacks a robust platform-independent framework for building desktop applications. Given that [Java](https://www.oracle.com/ca-en/java/) libraries can now be utilized in Ruby code through JRuby, Eclipse technologies, such as [SWT](https://www.eclipse.org/swt/), JFace, and RCP can help fill the gap of desktop application development with Ruby.
## Software Architecture
There are several requirements for building enterprise-level/consumer-level desktop GUI applications:
- Cross-Platform Support (Mac, Windows, Linux) without compilation/recompilation
- OS Native Look & Feel
- High Performance
- Productivity
- Maintainability
- Extensibility
- Native Executable Packaging
- Multi-Threading / Parallel Programming
- Arbitrary Graphics Painting
- Audio Support
Glimmer provides cross-platform support that does not require Ruby compilation (like Tk does), thanks to JRuby, a JVM (Java Virtual Machine) faster OS-threaded version of Ruby.
Glimmer leverages SWT (Standard Widget Toolkit), which provides cross-platform widgets that automatically use the native GUI libraries under each operating system, such as Win32 on Windows, Cocoa on Mac, and GTK on Linux.
Furthermore, what is special about SWT regarding "High Performance" is that it does all the GUI painting natively outside of Java, thus producing GUI that runs at maximum performance even in Ruby. As such, you do not need to worry about Ruby dynamic typing getting in the way of GUI performance. It has ZERO effect on it and since SWT supports making asynchronous calls for GUI rendering, you could avoid blocking the GUI completely with any computations happening in Ruby no matter how complex, thus never affecting the responsiveness of GUI of applications while taking full advantage of the productivity benefits of Ruby dynamic typing.
Glimmer takes this further by providing a very programmer friendly DSL (Domain Specific Language) that visually maps lightweight Ruby syntax to the containment hierarchy of GUI widgets (meaning Ruby blocks nested within each other map to GUI widgets nested within each other). This provides maximum productivity and maintainability.
Extensibility has never been simpler in desktop GUI application development than with Glimmer, which provides the ability to support any new custom keywords through custom widgets and custom shells (windows). Basically, you map a keyword by declaring a view class matching its name by convention with a GUI body that simply consists of reusable Glimmer GUI syntax. They can be passive views or smart views with additional logic. This provides the ultimate realization of Object Oriented Programming and micro-level MVC pattern.
Thanks to Java and JRuby, Glimmer apps can be packaged as cross-platform JAR files (with JRuby Warbler) and native executables (with Java Packager) as Mac APP/DMG/PACKAGE or Windows EXE/MSI.
The Java Virtual Machine already supports OS-native threads, so Glimmer apps can have multiple things running in parallel with no problem.
SWT supports Canvas graphics drawing, and Glimmer takes that further by provding a Canvas Shape/Transform/Animation DSL, making it very simple to decorate any existing widgets or add new widgets with a completely custom look and feel if needed for branding purposes.
Audio is supported via the Java Sound library in a cross-platform approach and video is supported via a Glimmer custom widget, so any Glimmer app can be enhanced with audio and video where needed.
### Remaining Challenges
JRuby startup time is longer than that of CRuby, but has gotten a lot faster with newer CPUs, especially the latest Mac ARM64 processors (it is now about 2.5 seconds on Mac ARM64 processors like the M1 chip). Thankfully, [there are work-arounds](https://andymaleh.blogspot.com/2021/03/glimmer-dsl-for-swt-41900-halved.html) that could make apps start as fast as instantly when needed.
Contributors who appreciate Glimmer's ultra-high productivity, maintainability, and extensibility might want to help report and resolve remaining challenges in its software architecture.
## Platform Support
Glimmer runs on the following platforms:
- Mac
- Windows
- Linux
Glimmer's GUI has the native look and feel of each operating system it runs on since it uses SWT behind the scenes, which leverages the following native libraries:
- Win32 on Windows
- Cocoa on Mac
- GTK on Linux
More info about the SWT GUI on various platforms can be found on the Eclipse WIKI and SWT FAQ:
https://wiki.eclipse.org/SWT/Devel/Gtk/Dev_guide#Win32.2FCocoa.2FGTK
https://www.eclipse.org/swt/faq.php
## Pre-requisites
- JDK 21 is recommended / JDK 16 is the minimum except on Mac ARM64 where JDK 17 is the minimum (find at https://www.oracle.com/java/technologies/downloads / Ensure `PATH` env var includes Java bin directory for `jpackage` command to work when packaging Glimmer applications / Preferably setup `JAVA_HOME` env var too to point to JDK home directory before installing JRuby)
- [RVM](http://rvm.io) on Mac & Linux (not needed on Windows)
- JRuby 9.4.5.0 (supporting Ruby 3.1.x syntax) (get via [RVM](http://rvm.io) on Mac and Linux by running `rvm install jruby-9.4.5.0`; On Windows, find at [https://www.jruby.org/download](https://www.jruby.org/download))
- Git (comes with Mac and Linux. Install on Windows: https://git-scm.com/download/win )
Glimmer might still work on other versions of Java, JRuby and SWT, but there are no guarantees, so it is best to stick to the pre-requisites outlined above.
To change the SWT version to a custom `swt.jar` version that you have, simply set the 'SWT_JAR_FILE_PATH' env var.
## Setup
Please follow these instructions to make the `glimmer` command available on your system via the [`glimmer-dsl-swt`](https://github.com/AndyObtiva/glimmer-dsl-swt) gem.
If you intend to learn the basics of Glimmer but are not ready to build a Glimmer app yet, pick Option 1 ([Direct Install](#option-1-direct-install)).
If you intend to build a Glimmer app from scratch with [scaffolding](https://github.com/AndyObtiva/glimmer-dsl-swt/blob/master/docs/reference/GLIMMER_COMMAND.md#scaffolding), pick Option 1 ([Direct Install](#option-1-direct-install)) as well.
Otherwise, Option 2 ([Bundler](#option-2-bundler)) can be followed in rare cases where you want to build an app without [scaffolding](https://github.com/AndyObtiva/glimmer-dsl-swt/blob/master/docs/reference/GLIMMER_COMMAND.md#scaffolding).
**Note:** if you encounter any [issues](https://github.com/AndyObtiva/glimmer-dsl-swt/issues), please [report](https://github.com/AndyObtiva/glimmer-dsl-swt/issues) and then install a previous version instead from the list of [Glimmer Releases](https://rubygems.org/gems/glimmer-dsl-swt/versions) (keep looking back till you find one that works). Do not be disheartened as nearly everything is only a few days of work away. That said, keep in mind that this project is free and open source, meaning provided as is, so do not expect anything, but if you help with reporting and contributing, you could speed things up or even become part of the project.
### Option 1: Direct Install
(Use for [Scaffolding](https://github.com/AndyObtiva/glimmer-dsl-swt/blob/master/docs/reference/GLIMMER_COMMAND.md#scaffolding))
Run this command to install directly:
```
jgem install glimmer-dsl-swt
```
Or this command if you want a specific version:
```
jgem install glimmer-dsl-swt -v 4.30.0.0
```
`jgem` is JRuby's version of `gem` command.
RVM allows running `gem install` directly as an alias.
Otherwise, you may also run `jruby -S gem install ...`
Afterwards, you can use `glimmer` and `girb` commands.
On the Mac, you also have to run:
```
glimmer-setup
```
This ensures configuring required Mac jruby options before using `glimmer` and `girb` commands (adding `export JRUBY_OPTS="$JRUBY_OPTS -J-XstartOnFirstThread"` to `~/.zprofile` and `~/.bash_profile`).
If you are new to Glimmer and would like to continue learning the basics, you may continue to the [Glimmer Command](#glimmer-command) section.
Otherwise, if you are ready to build a Glimmer app, you can jump to the [Glimmer Scaffolding](https://github.com/AndyObtiva/glimmer-dsl-swt/blob/master/docs/reference/GLIMMER_COMMAND.md#scaffolding) section next.
Note: if you're using activerecord or activesupport, keep in mind that Glimmer unhooks ActiveSupport::Dependencies as it does not rely on it.
### Option 2: Bundler
(Use for Manual App Creation)
Add the following to `Gemfile`:
```
gem 'glimmer-dsl-swt', '~> 4.30.0.0'
```
And, then run:
```
jruby -S bundle install
```
Note: if you're using activerecord or activesupport, keep in mind that Glimmer unhooks ActiveSupport::Dependencies as it does not rely on it.
You may learn more about other Glimmer related gems ([`glimmer-dsl-opal`](https://github.com/AndyObtiva/glimmer-dsl-opal), [`glimmer-dsl-xml`](https://github.com/AndyObtiva/glimmer-dsl-xml), and [`glimmer-dsl-css`](https://github.com/AndyObtiva/glimmer-dsl-css)) at [Multi-DSL Support](#multi-dsl-support)
## Glimmer Command
[docs/reference/GLIMMER_COMMAND.md](docs/reference/GLIMMER_COMMAND.md)
You can use the glimmer command to scaffold new apps, run apps & samples, package native executables, and list Glimmer community gems.
```

## Glimmer GUI DSL Syntax
[docs/reference/GLIMMER_GUI_DSL_SYNTAX.md](docs/reference/GLIMMER_GUI_DSL_SYNTAX.md)
Here is a listing of supported widgets taken from the [SWT website](https://www.eclipse.org/swt/widgets/):
[](https://www.eclipse.org/swt/widgets/)
In a nutshell, the Glimmer GUI DSL syntax consists mainly of:
1. Keywords
Widgets are declared with keywords denoting their name in underscored format.
Example of a keyword representing a table widget:
```ruby
table
```
Widgets may optionally receive symbol-style/args within parentheses (otherwise, when there are no style/args, the parentheses are left out).
Example of a multi-line selection table widget:
```ruby
table(:multi)
```
2. Content/Properties
Widget content is always housed within a curly-brace (`{}`) style block.
Example of a multi-line selection table widget with a table column as content that has a header `text` property as 'Name'.
```ruby
table(:multi) {
table_column {
text 'Name'
}
}
```
3. Listeners
Listeners embody the [Observer Design Pattern](https://en.wikipedia.org/wiki/Observer_pattern) and always start with `on_` followed by an event name (e.g. `on_widget_selected`). Also, they are an exception to Glimmer's syntax that requires a `do; end` style block to clearly demarcate as logic as opposed to View syntax.
Example of a button widget with a `text` property and an `on_widget_selected` listener.
```ruby
button {
text 'Click'
on_widget_selected do
message_box {
text 'Clicked'
message 'Thank you for clicking!'
}.open
end
}
```
4. Methods
Widgets have methods that invoke operations on them. Sometimes, they are required to be called in order to display the widgets (like the `open` method on `shell` and `message_box`)
Example of a shell with a `text` property and an invoked `open` method operation.
```ruby
shell {
text 'Hello, World!'
}.open
```

## Packaging & Distribution
Glimmer simplifies the process of native-executable packaging and distribution on Mac and Windows via a single command:
```
glimmer package
```
Learn more at: [docs/reference/GLIMMER_PACKAGING_AND_DISTRIBUTION.md](docs/reference/GLIMMER_PACKAGING_AND_DISTRIBUTION.md)
## App Updates
Glimmer should have support for automatic (and manual) app updates via the Mac App Store on the Mac (not tested yet, so contributor help is appreciated). Getting on the App Store requires running the `glimmer package` command with the Mac App Store keys configured as per the [Mac Application Distribution](mac-application-distribution) instructions.
## Glimmer Supporting Libraries
Here is a list of notable 3rd party gems used by Glimmer:
- [juwelier](https://rubygems.org/gems/juwelier): generates app gems during [Glimmer Scaffolding](https://github.com/AndyObtiva/glimmer-dsl-swt/blob/master/docs/reference/GLIMMER_COMMAND.md#scaffolding)
- [logging](https://github.com/TwP/logging): provides extra logging capabilities not available in Ruby Logger such as multi-threaded buffered asynchronous logging (to avoid affecting app performance) and support for multiple appenders such as stdout, syslog, and log files (the last one is needed on Windows where syslog is not supported)
- [nested_inherited_jruby_include_package](https://github.com/AndyObtiva/nested_inherited_jruby_include_package): makes included [SWT](https://www.eclipse.org/swt/)/[Java](https://www.java.com/en/) packages available to all classes/modules that mix in the Glimmer module without having to manually reimport
- [os](https://github.com/rdp/os): provides OS detection capabilities (e.g. `OS.mac?` or `OS.windows?`) to write cross-platform code inexpensively
- [puts_debuggerer](https://github.com/AndyObtiva/puts_debuggerer): helps in troubleshooting when adding `require 'pd'` and using the `pd` command instead of `puts` or `p` (also `#pd_inspect` or `#pdi` instead of `#inspect`)
- [rake](https://github.com/ruby/rake): used to implement and execute `glimmer` commands
- [rake-tui](https://github.com/AndyObtiva/rake-tui): Rake Text-based User Interface. Allows navigating rake tasks with arrow keys and filtering task list by typing to quickly find an run a rake task.
- [rouge](https://github.com/rouge-ruby/rouge): Ruby syntax highlighter used in the `code_text` [Glimmer DSL for SWT custom widget](#custom-widgets) leveraged by the [Glimmer Meta-Sample](/docs/reference/GLIMMER_SAMPLES.md#samples)
- [super_module](https://github.com/AndyObtiva/super_module): used to cleanly write the Glimmer::UI:CustomWidget and Glimmer::UI::CustomShell modules
- [text-table](https://github.com/aptinio/text-table): renders textual data in a textual table for the command-line interface of Glimmer
- [warbler](https://github.com/jruby/warbler): converts a Glimmer app into a Java JAR file during packaging
## Glimmer Process
[Glimmer Process](https://github.com/AndyObtiva/glimmer/blob/master/PROCESS.md) is the lightweight software development process used for building Glimmer libraries and Glimmer apps, which goes beyond Agile, rendering all Agile processes obsolete. [Glimmer Process](https://github.com/AndyObtiva/glimmer/blob/master/PROCESS.md) is simply made up of 7 guidelines to pick and choose as necessary until software development needs are satisfied.
