# Toy
|
|
|
|
This is the Toy programming language interpreter, written in C.
|
|
|
|
Special thanks to http://craftinginterpreters.com/ for their fantastic book that set me on this path.

# 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 external libraries
|
|
* 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.
|
|
|
|
Note: MacOS is not officially supported (no machines for testing), 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
|
|
```
