Hello World

Tutorial to help you create your first Ruota application.

Tutorial

The printl function

The

printl

function outputs a specified string to the console window.

printl("Hello, World!");

Then on your console window you would see the following:

Hello, World!

Disecting the program

Lets disect this program and see how it works,

printl

is clearly the name of the function, the brackets

(

and

)

indicate the beginning and start of a list of arguments for the function (if the function required no arguments you still add the brackets but without anything inside them), then

"Hello, World!"

is a string (a list of characters/words) which is the first argument for the

printl

function. The semicolon at the end lets Ruota know you're done with that command/function.

Comments

Just as a quick note, if you want to leave quick notes in your code for fellow developers to better understand your code (and even you coming back after some time), you use comments. Comments are defined by the 'hashtag' character, anything after that character will be ignored, meaning you can comment your code like this;

# this function outputs data to the screen

printl("yes hello that's me");
