sylk

Simple fully turing complete programming language that include almost all of the features of a common programming language.

Building

Just use make. The project have no dependencies.

If you want to run the tests you need to install google test. After you install it just run make test and then ./sylk_test.

Running

./sylk examples/fibonacci.slk to run an example.

If you want to use the interpreter as a lib you just need to include the sylk.h header from the src directory to use the functions and link the sylk library.

Documentation

Variable declaration

to declare a variable you need to use the var keyword.

var a
var b

you can also initialize the variables.

var text = 'hello world'

Function declaration

to declare a function you need to use the def keyword.

def square(n) {
    return n * n
}

Class declaration

to declare a function you need to use the class keyword

class Test {
    var a
    var b

    def constructor(a, b) {
        self.a = a
        self.b = b
    }

    def add() {
        return self.a + self.b
    }
}

Members are declared with the var keyword like variable declarations but the can't be initializated.

The constructor is declared as a normal method but it needs to be named constructor.

You can access the instance in a method with the self keyword.

note first you need to declare the members and then the methods or it will not compile

Conditionals

The conditionals works like in any other programming language

if a == 2 {
    print(a * a)
}

while n > 0 {
    print(n)
    n = n - 1
}

note there is no for statement yet.

Assignment

you can assign a value to a variable with =

var b
b = 15

you can also assign a different type to a variable

var b = false
b = 'hello'
print(b)

note assignment is a statement and not an expression so you can't use assignments where expressions are required.

while n = next() {
    print(n)
}

the code above will not compile.

Roadmap

• arithmetic operations
• if/else
• assignments
• while
• function calls
• logical operations
• function defenitions
• string support
• classes
• list data structure
• garbage collector
• standard library
