Groovy Weekly #18
The Easter bunny is delivering the latest Groovy Weekly column!
With your chocolate eggs, you’ll get some bits of functional programming, a tutorial on Groovy traits, details of the JSON serialization performance improvements, and also get the chance of voicing your feedback on things like Groovy’s support of Java 8 lambda syntax, on the Ratpack async support, and more.

- Schalk Cronjé is playing around with Greyton, a Groovy DSL (on top of JClouds) to simplify cloud devops and is looking for feedback
- Schalk Cronjé is looking for volunteers to try the SMB / CIFS provider for his Groovy VFS library
- Dierk König shares a handy Groovy one-liner to print your local IP address from the command-line
- Dan Woods fell into the trap of using GStrings as keys for maps, and the follow up discussion on Twitter on the topic is worth a read
- Russ Miles finds Groovy elegant and simple for using nested data structures, adding to Spring Boot’s productivity too
- Monadic combinators in Groovy by Mark Perry
