Last week, I was in San Francisco for my tenth JavaOne! I had two sessions: one on the past / present / future of Java Platform-as-a-Service offerings, and one on programming language influences, and particularly how was Apache Groovy influenced, and how it also inspired other languages.
Here's the abstract:
And you can have a look at the slides below:
Apache Groovy is a multi-faceted language for the Java platform, allowing developers to code in a Java-friendly syntax, with great integration with the Java ecosystem, and powerful scripting and Domain-Specific Language capabilities, while at the same time being able to offer you type safety and static compilation.
In this presentation, I revisited some of the influences from other languages, from the C-family and its Java older brother, going through its Python-inspired strings, its Smalltalk and Ruby heritage for named parameters and closures, its type system à-la-Java. But I'm also showing some of the innovations Groovy came up with that were later borrowed by others (Swift, C#, Kotlin, Ceylon, PHP, Ruby, Coffeescript...). Things like Groovy's trailing closure, Groovy builders, null-safe navigation, the Elvis operator, ranges, the spaceship operator, and more.
Ultimately, inspiration is really a two-way street, as languages don't come from nowhere and inherit from their older brothers and sisters. No language is perfect, but each one of them somehow help the next ones to get better, by borrowing here and there some nice features that make developers more productive and write more readable and maintainable code.
