interpreted programming language for super-fast scripting.

License Language

The Language

Arturo is a modern programming language, vaguely inspired by various other ones - including but not limited to Ruby, Haskell, D, SDL, Tcl and Lisp.

It is built on some very simple and straightforward principles:

Everything is a simple statement

There are no "special" language constructs (even `if` is nothing but a simple statement). Everything you see is a statement in the form ID <expression> <expression> <expression> ...

Code is data - and data is code

Arturo can be used both as a data-interchange format and a programming language. Basically all data structures are valid code and all code can be represented as a data structure. Think of it as SDL/Json/YAML/XML combined with the power of Lisp - but without the... sea of opening and closing parentheses.

Each statement returns a value

Whether what you would consider a "function" or any other statement, it will return a value. If it's a block of code (see: function), the last statement's result will be return - unless specified otherwise.

Functions are first-class citizens

Functions - or blocks of statements enclosed in {} - can be anything. Assign them to a symbol/variable, pass them around as arguments to function calls, include them as a dictionary key value, or return them from a function. And of course they can be either named or anonymous/lambda.

Uniform syntax

As already mentioned, everything is a statement of the form ID <expressions>. So, how does this work?

  • Is it the first time you are declaring this symbol? Then, the right-hand value will be assigned.
  • Is it not the first time? Then again, the right-hand value will be assigned.
  • Do you want to call a function you have declared, by name? Just prefix it with an exclamation mark. E.g.: !myFunc "some arg" "another arg"
  • Do you want to use the result of a function call as part of an expression? Just enclose the function call in $(...) E.g.: print $(reverse #(1 2 3))

Simple, isn't it?

Getting Started

Hello World

"Hello World"

or...

print "Hello World"

Declaring some data

num 	10
str 	"this is a string"

arrA 	1 2 3
arrB 	"one" "two" "three"
arrC	#(1 2 3)

dict 	#{
	name 	"john"
	surname "doe"
	age 	33
	address #{
		city	"Granada"
		country	"Spain"
	}
}

Declaring a function

addNumbers {
	@0 + @1
}

or...

addNumbers [x,y]{
	x + y
}

Fibonacci

maxLimit 20 // $(toNumber &0)

fib $(memoize [x]{
	if x<2 { 1 }{
		$(!fib x-1) + $(!fib x-2)
	} 
})

loop $(range 0 maxLimit) {
	print $(!fib &)
}
