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.
This repository holds the reference implementation for Toy version 2.x, written in C.
- Simple C-like/JS-like syntax
- Intermediate AST representation
- Strong, but optional type system
- First-class functions and closures
- Extensible with importable native code
- Can re-direct output, error and assert failure messages
- Open-Source under the zlib license
The following examples aren't fully functional yet - see the 'features' label in the issue tracker for more information.
//fizzbuzz example
for (var counter: int = 1; counter <= 100; i++) {
var result: string = "";
if (counter % 3 == 0) {
result = result .. "fizz";
}
if (counter % 5 == 0) {
result = result .. "buzz";
}
if (result != "") {
print result;
}
else {
print counter;
}
}
//find the nth fibonacci number
fn fib(n: int) {
if (n < 2) return n;
return fib(n-1) + fib(n-2);
}
for (var i = 1; i <= 10; i++) {
print i.toString() .. ":" .. fib(i).toString();
}
//closures!
fn makeCounter() {
var count = 0;
fn next() {
return ++count;
}
return next;
}
var tally = makeCounter();
print tally(); //1
print tally(); //2
print tally(); //3
Supported platforms are: linux-latest, windows-latest, macos-latest, using GitHub's standard runners.
Support for NetBSD is present, but not guaranteed.
To build the shared library, run make source.
To build the shared library and repl, run make repl.
To build and run the test suites, run make tests (make tests-gdb and make tests-valgrind options are also available).
