About:
Lfe is a Lisp syntax front-end for the Erlang Virtual Machine (BEAM), enabling developers to write concurrent, distributed, and fault-tolerant applications using classic Lisp macros and semantics. It seamlessly interoperates with existing Erlang libraries and tools, combining the expressiveness of Lisp with the robustness of the Erlang ecosystem.
Key Features:
  • Lisp-2 syntax with macros running on the BEAM
  • Full interoperability with Erlang modules and OTP
  • Dynamic compilation and interactive REPL
  • Powerful macro system for metaprogramming
Use Cases:
  • Building scalable, fault-tolerant backend services
  • Rapid prototyping of concurrent systems
  • Metaprogramming and DSL creation for Erlang/OTP
Alternatives:
  • Erlang – Erlang offers native syntax; Lfe provides Lisp-style macros and s-expressions
  • Elixir – Elixir uses Ruby-like syntax; Lfe offers Lisp syntax and macro capabilities
