Golo is a simple and lightweight dynamic language for the JVM.
Golo is a simple and lightweight dynamic language for the JVM.
You can see the OO Hello World series post here: http://carlosqt.blogspot.com/2010/06/oo-hello-world.html where I give some details on why these "oo hello world series" samples.
Version 1 (Minimal):
The minimum you need to type to get your program compiled and running.
module blog.series
function Greet = |name| ->
DynamicObject():
name(name: substring(0,1): toUpperCase()
+ name: substring(1, name: length())):
define("salute", |this| -> println("Hello " + this: name() + "!"))
function main = |args| {
let g = Greet("world")
g: salute()
}
Version 2 (Verbose):
Explicitly adding instructions and keywords that are optional to the compiler.
module blog.series
local function Greet = |name| ->
DynamicObject():
name(name: substring(0,1): toUpperCase()
+ name: substring(1, name: length())):
define("salute", |this| -> println("Hello " + this: name() + "!"))
function main = |args| {
let g = Greet("world")
g: salute()
}
The Program Output:
Golo Info:
Golo is a simple, dynamic and weakly-typed language that favours explicit over implicit and that runs on the Java Virtual Machine. It also supports the latest JVM features such as invokedynamic.
