# Preamble
|
|
|
|
The Toy programming language is a procedural bytecode-intermediate interpreted language. It isn't intended to operate on it's 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.
|
|
|
|
```
|
|
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
|
|
```
