Hi, total noober here.
in my app.d i have added this function:
int hello(){
return 3;
}
//end
...how can i call this function in my index.dt? I tried:
block body
h1 Example page - Home
p hey #{hello()}
did i miss the example in your documentation on the website? i
got some simple addition to work, but i can't call a function.
thank you

If I'm not mistaken (noob here too), #{variable} is variables you pass to
the template from your code, or variables you create in the diet template.
You can call functions be prepending an -
block body
-auto msg = hello();
p #{msg}
it might also work with
-auto msg = hello();
p= msg
Or even (but I dont think so):
p= hello();
You might need to import your file first, but that is as easy as:
- import yourmodule;

You need to make the function visible to the template first. There are
three possibilities for this:
inside the template, import the module that defines the function:
block body
- import mymodule;
h1 Example page - Home
p hey #{hello()}
Pass the function as a template argument to res.render() - note that
res.render() has some issues in DMD 2.059 and I wouldn't recommend to
use it yet:
res.render!("home.dt", hello);
Do the equivalent with res.renderCompat():
res.renderCompat!("home.dt", "hello")(Variant(&hello));
I've added a ticket for the website to remember adding an example to the
documentation.

All three methods should work, except that "p= ..." expects an
expression, so it's just "p= hello()".

Thanks to D's function local imports! Nice little feature.
Btw. a reference for the template syntax is on my TODO list for the next
days.
