Using interactive playground explain concepts and ask to program specific things.

Program that does nothing

Concepts to explain

• Ports
• Components
• Special enter and exit ports
• Stdlib and flow package
• Trigger builtin component
• Static inports and int datatype

Create program with main component that has enter inport and exit outport. Both inport and outport must be generic and accept type parameter. Then import and use trigger from flow package and make it's v inport static with int value 0. Then connect enter to trigger.in.sig and trigger.out.v to exit. As a result program will terminate with exit code 0.

Hello world

• str data-type
• io package and Print component
• unused outports

Echo

Program that reads the line from stdin and then prints it back to stdout.

...

Factorial

Fibonacci

...

Static outports.

Revisiting Program that does nothing and hello world (maybe echo too?)

...

Real use case for trigger

• Several signals?
• Cases where we also need actual value?

Metaphors section

It would be great if every lesson/article would include not only technical description of how things really work but also an example from real life

Factorial

Python reference

def facr(x):
    if x == 1:
        return 1
    return x*facr(x-1)


def facl(x):
    c = 1
    for i in range(2, x+1):
        c = c * i
    return c


def facl2(x):
    c = 1
    i = c
    while i < x:
        i += 1
        c *= i
    return c


print(facr(5))
print(facl(5))
print(facl2(2))
