Go Skrip

Usage

Execute from file

skrip run main.sk

Execute from inline code

skrip eval 'print("1234")'

skrip eval 'let a="this is a test";print(a)'

Syntax

Define variable

let name = "foo";
let age  = 8;
let boy  = true;
let tail = 17.2;

Define array

let array1 = [1,2,3];
let array2 = ["foo", "bar", 1, 2.2];

println(array1[1]);

Define hash

let hash1 = {"a": 1, "b": 2};
let hash2 = {1: "a", "b": 3.2};

println(hash1["a"]);

If statement

if (name == "foo") {
    println("hello");
}else if (name == "bar") {
    println("hi");
}else{
    println("bye");
}

For statement

for item in [1,2,3.2,"foo","bar"] {
    println(item)
}

for item in 1..3 {
    println(item)
}

for key, item in {"a": "foo", "b": "bar"} {
   println(key + " => " + item)
}

Forever loop statement

let x = 1;

for {
    x = x + 1;

    println(x);

    if (x == 10) {
        break;
    }
}

Function

func name(first, last) {
    return first + " " + last;
}

println(name("tom", "cat"));

let name2 = func(first, last) {
    return last + " " + first;
};

println(name2("tom", "cat"));

Syntax sugar

let cat = {};
cat.name   = "tom";
cat.gender = "???";
println(cat.name + "," + cat.gender);

Development

Using the go module by default

export GO111MODULE=on

Install the test package

go get github.com/smartystreets/goconvey

Run the command to eval file

go run *.go run ./test.sk

Run the command to eval inline code

go run *.go eval 'print("1234")'

go run *.go eval 'let a="this is a test";print(a)'

Testing

Run all test case

go test ./... -count

Run all test case in specify the package

go test ./parser -count=1

Run selected test case in specify the package

go test ./evaluator -run "TestForEachHashExpression"
