Usage of external function will end the story immediately

[julhe]

To reproduce:

EXTERNAL Foo()
Hello World!
~ Foo()

Output is just End of Story.

When removing ~ Foo() however, Hello World! is printed as expected.

It's actually crashed - functions need to be defined in the ink script ("a fallback" that inky uses). Without a === function Foo() the ink doesn't compile and run. So there is a bug here - but it's the lack of a proper error message.

The correct way is to define a function too in inky

~ Foo()

EXTERNAL Foo()
=== function Foo()
Hello World!
~ return
