Red Hat ships piping hot Ceylon to curry favor with Java-weary devs

Filed under
Software

After more than three years of development, Red Hat has released version 1.0.0 of Ceylon, its homebrewed, open-source programming language that's designed to be a replacement for Java.

Early on, Ceylon was billed as a "Java killer" by some, but lead developer Gavin King has denied that doing away with Oracle's platform was ever his intent. In fact, even the earliest builds of Ceylon produced code that ran on the Java Virtual Machine (JVM).

Instead, King sought to create a new language that could run alongside Java but would be based on more modern class libraries and would have a syntax more amenable to defining user interfaces – something King believes there is "no good way" to do in Java.

In its current form, King describes Ceylon as a "cross-platform" language. The 1.0.0 release, announced at the Devoxx conference in Antwerp, Belgium on Tuesday, includes compilers that can output either Java bytecode or JavaScript.

That allows the same Ceylon source modules to run on either the JVM or a JavaScript execution environment such as Node.js, interchangeably. Or, a Ceylon program can be written to target only one of Java or JavaScript, in which case it can interoperate with native code written in that language.
