Template:Infobox programming language AntLang is a functional scripting language named after its creator Anthony Cipriano. Its main distinctive feature is short syntax oriented towards mathematical equations.

It is a combination of APL and M-Expressions (Yukihiro Matsumoto), which main strength is its short and concise syntax.

The first implementation of AntLang was written in Haskell, another one called OpenCally is a C framework and can be used as a library to write AntLang compilers.

Code examples

Simple math

 5*1+2 /=> 15

AntLang uses right-to-left evaluation, so 1+2 gets executed before 5*3.

Even though AntLang evaluates right-to-left, it is recommended to read left-to-right in a top-down manner.Template:Clarify

Hello World


The echo function is called with the string helloworld, prints it and returns it.


<source lang="J">

factorial:{1 */ 1+range[x]}


The times-reduction (*/) with the accumulator value 1 over the list 1+range[x].

Fibonacci sequence

<source lang="J">





hsAntLang was the first AntLang implementation, which is still used by most of AntLang users.

It fully implements the language standard plus several extensions, like multithreading, file Input/output and exception handling.

It is hosted on GitHub.


OpenCally is an AntLang compiler by AntLang Software.

It is under active development and doesn't support all the standard functions and syntax yet.

OpenCally adds interfaces to all its target languages (currently JavaScript): <source>

/ load the standard library
/ make a JavaScript function available to AntLang (prefix: v_)
js)v_console_log = console.log;
/ call that function from within AntLang
console_log each <"APL"; "Haskell"; "Erlang">


To execute the code above on a machine with OpenCally installed, run: <source lang="sh"> $ run-antlang file.ant </source>

It is also hosted on GitHub.
