tomevault-io Nim
Nim v2.0 (2023/2024) made ORC (Deterministic Memory Management) the default. It compiles to C/C++/JS and offers Python-like syntax with C-like speeds.
When to Use
- Game Development: Hot reloading and performance.
- Embedded: Compiles to small C code requiring no runtime.
- Scripting: Compiles so fast it feels like a script (
nim r).
Core Concepts
Metaprogramming
First-class support. You can rewrite the AST to create DSLs.
ORC
Cycle-collecting ARC. Automatic memory management without pauses.
Backends
Can compile to C, C++, Objective-C, or JavaScript.
Best Practices (2025)
Do:
- Use
ARC/ORC: The default in v2.0. Clean up is deterministic (destructors). - Use
f-strings:fmt"Hello {name}". - Use
karax: For frontend (compiling Nim to JS).
Don't:
- Don't mix styles: Choose PascalCase or camelCase (Nim is style-insensitive but consistency matters).
