Elixir – dynamic, functional language

Elixir is a functional, concurrent, general-purpose, open source meta-programming aware language built on top of the Erlang Virtual Machine (BEAM). It mostly imports Erlang’s syntax.

Elixir is a dynamic language with macros that leverages Erlang’s ability to build concurrent, distributed, and fault-tolerant applications with hot code upgrades. It combines the robust functional programming of Erlang with an approach that looks more like Ruby.

Elixir provides a first class macro mechanism, supports polymorphism via protocols (similar to Clojure’s) and many other features while keeping the functional aspects of Erlang.

Features include:

• Complete and automatic hardware detection.
• A language targeting Erlang Virtual Machine (BEAM).
• Protocol-based inheritance.
• Seamless Erlang integration: zero-penalty Erlang function calls (and vice versa).
• Meta programming via macros and a first-class AST.
• Polymorphism via protocols inspired by Clojure.
• Shared-nothing concurrent programming via message passing (Actor model).
• Emphasis on recursion and higher-order functions instead of side-effect-based looping.
• Everything is an expression.
• Message passing.
• Pattern matching.
• Provides both lists, tuples, and a special syntax to create a list of keywords.
• Support for streams, sets.
• Support for reducers.
• Metaprogramming via macros.
• Unicode support and UTF-8 strings.
