Updated Nov 20, 2025
Architecture
Source code compiled to C/C++ or JS
Garbage-collected or manual memory management
Procedural, OOP, and functional constructs coexist
Macros allow compile-time code transformation
Modules and packages organize code
Rendering Model
Source code compiled to C/C++/JavaScript
Garbage-collected runtime for memory safety
Modules organize code and dependencies
Macros expand code at compile-time
Binaries executed natively on supported platforms
Architectural Patterns
Procedural and functional pipelines
OOP for encapsulation
Macro-based code generation
Async tasks for concurrency
Module-based project structure
Real World Architectures
CLI tools and utilities

Cross-platform native binaries
Design Principles
Readable syntax similar to Python
Statically typed with type inference
High-performance native compilation
Metaprogramming with macros
Cross-platform compatibility
Scalability Guide
Use modules for large projects
Leverage macros for reusable patterns
Profile memory and performance
Parallelize async tasks where possible
Organize code with Nimble packages
Migration Guide
Port older Nim code to current compiler
Refactor macros for modern syntax
