Basics

Basics of i

##Variables Variables can be created with the "var" keyword, just a warning: NO DECIMAL NUMBERS.

var n = 3
var s = "string"

If statements

If statements take numeric values, 0 is false, anything else is true.

if expression
    print("expression is true!")
elseif condition
    print("expression is false...")
    print("but condition is true!")
else
    print("expression and condition are false...")
end

##Switch statements Switched in I are syntactic sugar for if-else chains. They are not faster (yet). Only numeric values are supported.

switch expression {
    case 0
        print("expression is zero")
    case 1
         print("expression is one")
    default
         print("expression is not one or zero")
}

##Loops The loop statement loops over the enclosed block of code an unspecified amount of times, it's up to you to break out of the loop when you need to.

loop {
    if leaving
        break
    end
}

##For Loop The for loop is more useful as it strictly specifies how many times the loop will run.

for element in array
    print(element)
    if bad(element)
        delete() //--This deletes the element (does not preserve order)
    end
end

for id, value in array
    print(id, ":", element)
end

for n over [0, 10]
    print(n)
end

for id over array
    print(id)
end

Issues

The issues block will run if there has been an error, the explanation mark is used to clear the status of any previous errors and that we are interested in future errors.

!var n = number("abc")
issues {
    print("Could not convert abc to a number!")
}
