YASS examples for real ideas.

Start with a small program, understand the shape of it, and then make it your own. These examples are here to show how YASS reads and what ZPE can do with it.

The basics

Give an idea a name

Functions keep a useful piece of behaviour together and make it easy to use again.

function greet($name)
  return "Hello " + $name
end function

print(greet("Jamie"))

Hello Jamie

{ }

Data and records

Describe the things you use

Records provide a clear way to group related values and construct named data.

record pupil
  forename = ""
  surname = ""
  age = 0
end record

$pupil = new pupil(surname = "Smith", age = 35)
print($pupil)

{forename:"", surname:"Smith", age:35}

</>

Web pages

Keep the page close to the code

YASS Web Pages combine a normal page structure with a small amount of dynamic application code.

<?ywp
$page_title = "Welcome"
$name = "Jamie"
render("/templates/base.ywp")
ywp?>

<h1>Hello <?ywp print($name) ywp?></h1>

Hello Jamie

Algorithms

Make repetition readable

YASS gives common programming tasks a direct shape without hiding what the program is doing.

$numbers = [1, 2, 3, 4, 5]
$total = 0

for ($number in $numbers)
  $total = $total + $number
end for

print($total)

Keep going

These are starting points, not limits.

Use the same language for automation, websites, native applications, data processing and the projects you have not thought of yet.
