Fig Language - A Modern Scripting Language
The repository has been migrated from github! No more updates. New repository: Fig
Fig is a statically-typed, expression-oriented programming language designed for clarity, safety, and modern development practices. With features inspired by Go, Rust, and JavaScript, Fig aims to provide a productive development experience while maintaining strong type safety.
Features
🚀 Core Language Features
- Static typing with type inference - Strong typing with minimal annotations
- Modern control flow - Full
forloop support with proper scoping - First-class functions - Lambda expressions and closures
- Rich data structures - Structs, lists, maps, and tuples
- Memory safety - No null pointer exceptions, automatic memory management
🔧 Technical Highlights
- Three-level scoping for loops - Proper variable isolation in iterations
- Smart semicolon handling - Flexible statement termination with RAII guards
- Comprehensive error handling - Detailed error messages with source locations
- Clean C++ implementation - Modern C++23 with RAII and smart pointers
🔧 Install

Language Philosophy
Fig is designed around several core principles:
Clarity over cleverness - Code should be readable first
Safety by default - Prevent common errors at compile time
Modern ergonomics - Developer experience matters
Gradual learning - Simple to start, powerful when needed
