Hello, world!

Welcome to mers! Start by creating a file for your mers code:

println("Hello, world!")

now run it: mers <file> (replace mers the location of the compiled executable if it's not in your PATH)

basic concepts

variables

a = 15
println("a: " + a.to_string())
// clones the value
b = a
a = 25
println("a: " + a.to_string())
println("b: " + b.to_string())

if statements

// type: bool
condition = true
if condition {
    println("yes")
} else {
    println("no")
}

else-if statements

number = 15
if number == 10 {
    println("ten")
} else if number == 15 {
    println("fifteen")
} else {
    println("another number")
}

switch statements

condition = true
// type: string/int
val = if condition {
    "some text"
} else {
    15
}
// do different things depending on the type
switch! val {
    string println("text: " + val)
    int {
        // we need to convert val to a string before we can use it here
        println("number: " + val.to_string())
    }
}

match statements
