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

Principles

The language has been designed following some very simple and straightforward principles:

Code is just a list of words and symbols
Words and symbols within a block are interpreted - when needed - according to the context
No reserved words or keywords - look for them as hard as you can; there are absolutely none

print "Hello world!"

loop 1..10 'x [

   if? even? x -> print [x "is even"]
   else        -> print [x "is odd"]

]

Implementation

The main compiler is implemented in Nim/C as a Bytecode interpreter / Stack-based VM and should run in most architectures.

The main goals are: performance, energy-efficiency and portability. (With that exact order)

License

Arturo is released under the MIT/X11 License.

-'''Arturo''' is a general-purpose, multi-paradigm language that aims to be simple, modern and powerful, vaguely inspired by various other ones - including but not limited to [[Ruby]], [[Haskell]], [[D]], [[SDL]] (Simple Declarative Language), [[Tcl]] and [[Lisp]].

 ===Principles===
-It is built on some very simple and straightforward principles:
+The language has been designed following some very simple and straightforward principles:
+* Code is just a list of words and symbols
-====Everything is a simple statement====
+* Words and symbols within a block are interpreted - when needed - according to the context
+* No reserved words or keywords - look for them as hard as you can; there are absolutely none
+<code>
-There are no "special" language constructs (*even `if` is nothing but a simple statement*). Everything you see is a statement in the form <code>ID <expression> <expression> <expression> ...</code>. An assignment is nothing but a labeled statement. <code>LABEL: <statement></code>
+print "Hello world!"
-<br>
-====Code is data - and data is code====
+loop 1..10 'x [
-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.
+    if? even? x -> print [x "is even"]
-<br>
+    else        -> print [x "is odd"]
-====Each statement returns a value====
+]
+</code>
+===Implementation===
-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.
+The main compiler is implemented in [[Nim]]/[[C]] as a Bytecode interpreter / Stack-based VM and should run in most architectures.

-====Functions are first-class citizens====
+The main goals are: performance, energy-efficiency and portability. (With that exact order)
-Functions - or blocks of statements enclosed in <code>{}</code> - 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.
-<br>
-====Uniform syntax====
-There are 3 types of statements.
-* Simple statements, that work as a function call in the form of <code>ID <expressions></code>
-* Expressions (Yes, <code>1+2</code> is also a valid statement)
-* Labeled statements (see: assignments)  like <code>a: 2</code>
-Pro tip: Do you want to use the result of a statement as part of an expression? Just enclose the function call in square brackets <code>[...]</code>	E.g.: <code>print [reverse #(1 2 3)]</code>
-===Implementation===
-The main Arturo interpreter is written in the [[Nim]] language.
