To help with storing strings within tables, I've replaced the unused '_padding' member of 'Toy_String' with 'cachedHash', which is set to zero on string allocation. The hash of a string isn't generated and stored until it's actually needed, as the rope pattern means not every string needs a hash - hopefully this will save unnecessarily wasted time. When a hash of a string is needed, the hashing function first checks to see if that string already has one, and if so, returns it. Again, less time wasted. When generating a new string hash, the hashing function takes the string's type into account, as node-based strings first need their contents assembled into a simple char buffer. Other changes include: * Changed 'TOY_VALUE_TO_*' to 'TOY_VALUE_FROM_*' * Changed 'TOY_VALUE_IS_EQUAL' to 'TOY_VALUES_ARE_EQUAL' * Added a missing '#pragma once' to 'toy_print.h'

Toy v2.x
The Toy programming language is an imperative, bytecode-interpreted, embeddable scripting language. Rather than functioning independently, it serves as part of another program, the "host". This design allows for straightforward customization by both the host’s developer and end users, achieved by exposing program logic through text files.
This repository holds the reference implementation for Toy version 2.x, written in C.
Nifty Features
- Simple C-like syntax
- Intermediate AST representation
- Strong, but optional type system
- First-class functions
- Extensible via external libraries
- Can re-direct output, error and assertion failure messages
- Open source under the zlib license
Syntax
print 42; //print is a built-in keyword
//more examples to be added as the features are implemented
