Build 1.0.70

Posted by brian – Wed 8 Nov 2017

New build is posted and online docs updated.

Java Support

The previous build 1.0.69 was compiled to target Java 1.5+, but in this build we are targeting 1.7+ or higher. So you will need to run with at least Java 1.7 now (we recommend Java 1.8). Hopefully this should not be a problem since 1.6 is over a decade old now. We'll probably upgrade to require 1.8+ sometime in 2018.

Also note that Java FFI is not going to work with 1.9 because they reworked jars and classpath for project Jigsaw. That will be a significant development effort to fix. In the meantime you will need to use JDK 1.8 when compiling Fantom code which uses Java FFI.

Build 1.0.69

Posted by brian – Thu 14 Jul 2016

I have posted new build and updated online docs.


We have finally open sourced domkit! We pushed all Andy's code to BitBucket last week. This is our new HTML5 toolkit which has been under development for on and off about a year. This library is still actively under development, so consider it beta. Might still be a few breaking API changes, but we are using it production now so its getting close. Take a look at the pod docs. Not much example code yet. We have a test harness that we probably need to look at moving over to Fantom repo too at some point soon.

Build 1.0.68

Posted by brian – Thu 7 Apr 2016

Its been long overdue, but we have finally posted 1.0.68!

Dom Changes

There have been many breaking changes to the dom APIs. This is in preparation for the development of a brand new UI toolkit called domkit which we hope to open source later this year. Domkit replaces FWT as our toolkit for developing HTML5 user interfaces in Fantom. See topic 2466 for more details, and please review change log for list of changes.
