    • Full annotation support
    • Enum support
  • Syntax for operator overloading
  • New mechanism for DGM and possible syntax for extension methods: a mixin category, inspiration from C# 3

features

  •  Continuations

Problems to address

  • Serialization issue
  • Registry clean-up (cf XWiki usage)
  • Refactor DGM into difference classes that deal with each type (Object, Map, List) for maintainability

Tooling

  • GroovyDoc
  • IDE plugins
  • Improved console

Build

  • Rework the build system (Gant, Ivy, m2)
  • Cleaning up the codebase (what can be removed, e.g. old eclipse plugin)
  • Coverage report
  • Move non core classes (AntBuilder, Mock...) out of main source tree and cut down jar dependencies
  • Make sure we still provide poms for M1 / M2 repository distribution
  • Continuous integration build

Distribution

  • Groovy-all should be the rule (no double jars all vs. not all)
  • Include a native launcher
  • Update dependencies (antlr 3, asm 3, ant 1.7, xerces 2.9, junit 4.2...)

...

  • Remove

...

  • unneeded

...

  • dependencies

...

  • from

...

  • the

...

  • distributions

...

  • (EJB,

Location

The Groovy Developer Conference #3 will be held in Paris.

Sun will provide us with a big room named "Jupiter" with video-projector and so on.
You can find the details for going to the Sun's offices there.

Dates

The conference will take place on 29 and 30 January 2007

(Other possible matching dates were 1-2 and 8-9 February 2007. The sooner, the better.)

The conference is a two days conference. All Groovy & Grails developers are welcome to this conference, and if space permits, we can potentially accept additional invitees.
