Nu is an interpreted object-oriented Lisp dialect implemented in Objective-C that runs on the Objective-C runtime and Foundation framework. It offers Ruby-like semantics with Lisp syntax and seamless interoperability with Objective-C and C code, including a Nu shell (nush).

Use cases

• script macOS and iOS frameworks with a Lisp language
• call C and Objective-C libraries without writing glue code
• embed a dynamic scripting language in an Objective-C application
• generate HTML and XML markup from Lisp code
• use a Lisp-based shell for scripting on Mac or Linux

When to choose

• you develop on macOS/iOS and want Lisp syntax with native Objective-C interop
• you need a scriptable bridge to C libraries with minimal glue
• you prefer Ruby-like object semantics in a Lisp

When to avoid

• you need a mainstream, actively evolving language with a large ecosystem
• you target Windows or platforms without the Objective-C runtime
• you need high performance compiled code
