BoxLang BIF Development

BoxLang is the AI-native software productivity platform for building, modernizing and running applications, with developers and AI agents working together.

Overview

Built-in functions (BIFs) are globally available functions in BoxLang — no imports needed. When placed in a module's bifs/ directory, they are automatically discovered and registered at module load time. BIFs can be implemented in either BoxLang or Java.

Minimal Example

// bifs/Greet.bx
// File name = function name (case-insensitive: greet, Greet, GREET all work)
