Golo/Roadmap-v3.0

Overview

The development of Golo 3.0.0 directly follows release 2.1.0, the last release that was made under the stewardship of INSA-Lyon before entering incubation at the Eclipse Foundation.

Golo 3.0.0 is a release performed under the Eclipse Incubation branding.

Milestones

We adopt a 6 weeks fixed schedule between milestones. The planning of milestones is organic.

3.0.0-incubation-M1 (2015/07/27)

• JDK 8 is now required.
• Support for Java 8 lambdas / functional interfaces.
• Support for named arguments, leveraging JDK 8 bytecode metadata.
• New union types.
• Operators priorities and left-associativity have been fixed in the LL(k) parser.
• Augmentations can now define a fallback method.
• New lazy lists.
• foreach loops can now have a guard condition.
• Function references are now represented using FunctionReference rather than straight MethodHandle.
• Decorators can now change function arities.
• Deprecated array methods and functions have been removed.
• Easier adapters generation API.
• CLI subcommands are now defined through a SPI for modularity and extensibility.
• The `fun` function can now retrieve instance methods.
• Fixes in arithmetic comparison operators.
• Fixes in special character escaping in String and char literals.
• Documentation generation is now self-contained with Asciidoctor instead of Asciidoc.

3.0.0-incubation-M2 (2015/09/07)

• Collection comprehensions, inspired by Python.
• The documentation is now generated with AsciiDoctor instead of AsciiDoc.
• Union types now have special methods synthesized from members to facilitate tests.
• The build has been migrated from Maven to Gradle.
• reversed_range has been renamed to reversedRange for consistency reasons.
• The new box(obj) predefined function boxes an object reference into a java.util.concurrent.atomic.AtomicReference. This is useful to inject mutable state into closures.

3.0.0-incubation-M3 (2015/10/19)

• Refactoring from fr.insalyon.citi.golo to org.eclipse.golo packages.
• FindBugs integration in the build process.
• Fixes have been applied to address the relevant FindBugs reports, and unappropriated ones have been silenced.
• Parser error traces have been simplified to avoid confusion.
• Misc fixes.

Golo 3.0.0-incubation-M3 marks the last milestone before branching and preparing a formal release. The development on the master branch immediately switches to Golo/Roadmap-v3.1.

Maintenance releases

There is no maintenance release planned at this stage.
