Hello Radiance

This week marks the beginning of a new phase for a bunch of my long-running open-source Swing projects. Some of them have started all the way back in 2005, and some have joined later on along the road. Over the years, they’ve been hosted on three sites (, and in three version control systems (cvs, svn, git). Approaching the 15th year mark (with a hiatus along the way), it’s clear that it’s time to revisit the fundamental structure of these projects and bring them into a more modern world.

Since these projects have been brought back to life in the last two years, the entire codebase has been revisited to clean up the cruft that has accumulated over time. Some of the explorations that I’ve embarked on have not went as well as I hoped they would be. That has been the fate of laf-plugin and laf-widget projects that aimed to bring common functionality across a variety of third-party look-and-feels, a field that is only seeing Substance and Synthetica as the two lone survivors.

Today I’m happy to announce the beginning of Project Radiance, the new umbrella brand that will unify and streamline the way Swing developers can integrate my libraries into their projects. At a high-level:

  • Radiance is a single project that provides a Gradle-based build that no longer relies on knowing exactly what to check out and where the dependent projects need to be located. It also uses proper third-party project dependencies to pull those at build time.
  • Starting from the very first release (planned for second half of 2018), Radiance will provide Maven artifacts for all core libraries – Trident (animation), Substance (look-and-feel), Flamingo (components), Ibis (SVG icons) and others.
  • The Kormorant sub-project is the first exploration into using Kotlin DSLs (domain-specific languages) for more declarative way of working with Swing UIs.
  • Flamingo components will only support Substance look-and-feel, no longer doing awkward and unnecessary tricks to try and support core and other third-party look-and-feels.

All the open bugs on existing GitHub projects have been migrated to be under Radiance. Once the migration of all the relevant documentation and older binaries to Radiance is complete in the next couple of weeks, those projects will be deleted from GitHub.

Starting from today, all new development such as bug fixes, feature work and documentation updates will only be done under Radiance. The versioning of all the projects will be unified going forward, resetting to 1.0. Some public APIs might move between sub-projects (going into Neon).
