This git branch is the (now deprecated) documentation website for The Toy Programming Language version 2.x, which can be found at [https://github.com/krgamestudios/Toy](https://github.com/krgamestudios/Toy).
# Toy
Toy v2.x is still under active development, so this documentation will change and evolve over time, and may not reflect the current reference implementation.
The Toy programming language is an imperative bytecode-intermediate embedded scripting language. It isn't intended to operate on its own, but rather as part of another program, the "host". This process is intended to allow a decent amount of easy customisation by the host's end user, by exposing logic in script files. Alternatively, binary files in a custom format can be used as well.
The host will provide all of the extensions needed on a case-by-case basis. Script files have the `.toy` file extension, while binary files have the `.tb` file extension.
This is the Toy programming language interpreter, written in C.
# Nifty Features
* Simple C-like syntax
* Bytecode intermediate compilation
* Optional, but robust type system (including `opaque` for arbitrary data)
* Functions and types are first-class citizens
* Import native libraries from the host
* Fancy slice notation for strings, arrays and dictionaries
* Can re-direct output, error and assertion failure messages
* Open source under the zlib license
## Building
For Windows(mingw32 & cygwin), Linux and MacOS, simply run `make` in the root directory.
For Windows(MSVC), Visual Studio project files are included.
Note: MacOS and Windows(MSVC) are not officially supported, but we'll do our best!
## Tools
Run `make install-tools` to install a number of tools, including:
* VSCode syntax highlighting
## Syntax
```
import standard; //for a bunch of utility functions
print "Hello world"; //"print" is a keyword
var msg = "foobar"; //declare a variable like this
assert true, "This message won't be seen"; //assert is another keyword
//-------------------------
fn makeCounter() { //declare a function like this
var total: int = 0; //declare a variable with a type like this
fn counter(): int { //declare a return type like this
return ++total;
}
return counter; //closures are explicitly supported
}
var tally = makeCounter();
print tally(); //1
print tally(); //2
print tally(); //3
```

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 developers and end users, achieved by exposing program logic through text files.
The documentation on this website is under construction, for further information, see the repository: [https://gitea.krgamestudios.com/krgamestudios/Toy](https://gitea.krgamestudios.com/krgamestudios/Toy), or the GitHub mirror: [https://github.com/krgamestudios/Toy](https://github.com/krgamestudios/Toy).

`Toy_Scope` holds the variables of a specific scope within Toy - be it a script, a function, a block, etc.
Scopes are also where the type system lives at runtime. They use identifier literals as keys, exclusively.
`Toy_RefString` is a utility class that wraps traditional C strings, making them less memory intensive and
faster to copy and move. In reality, since strings are considered immutable, multiple variables can point
to the same string to save memory, and you can just create a new one of these vars pointing to the original
rather than copying entirely for a speed boost. This module has it's own memory allocator system that is
plugged into the main memory allocator.
`Toy_RefFunction` acts similarly to `Toy_RefString`, but instead operates on function bytecode.
