Ceylon is an object-oriented, strongly statically typed programming language with an emphasis on immutability, created by Red Hat. Ceylon programs run on the Java virtual machine (JVM), and can be compiled to JavaScript. The language design focuses on source code readability, predictability, toolability, modularity, and metaprogrammability. Read more on Wikipedia...


Example from Riju:
shared void run() { print("Hello, world!"); }
Example from hello-world:
shared void hello() { print("Hello World"); }
// Hello world in Ceylon print("Hello, World!");
Example from Linguist:
"Test function for Ceylon" by ("Enrique") shared void test() { print("test"); } "Test class for Ceylon" shared class Test(name) satisfies Comparable<Test> { shared String name; shared actual String string = "Test ``name``."; shared actual Comparison compare(Test other) { return name<=>other.name; } }
Example from Wikipedia:
/* The classic Hello World program */ shared void run() { print("Hello, World!"); }
