VastNova 0 beta6 English Documentation

VastNova is a lightweight, easily embeddable scripting language designed for quick integration and interactive use. It features a minimalistic syntax, dynamic typing, arithmetic operations, conditionals, and I/O, making it ideal for game scripting, configuration files, or educational examples.

Features

• Minimal syntax: intuitive keywords like print / read (backward compatible with out / in)
• Dynamic typing: automatically distinguishes numbers and strings
• Arithmetic: + - * / with operator precedence
• Conditionals: > < == != and && ||, with string comparison support
• Interactive input: via input or read
• Comments: single-line // or #, multi-line !# ... #!
• Header-only, depends only on C++ standard library
