Re: [racket-users] multi line scribble text body in web-server template

This is so cool, thank you both!

So my quick fix is:
@when[#t]{
@list{
line1
line2
line3
}
}

And I have been using that Iteration Gotchas code, but I was using it 
blindly.
Now I can reason thru it better.

That's normal "when" behavior

```
Welcome to Racket v7.8.0.5 [cs].
> (when #t "first" "second")
"second"
```

One fix is to put a list of text in the `when` body. He's how I'd write it:

```
#lang at-exp racket

@(define (when-logged-in . pc*)
   (when #t
 pc*))

@when-logged-in{
  first
  second
}
```

[racket-users] multi line scribble text body in web-server template

2020-11-01 Thread krs...@gmail.com 

Hi!,

I am using web-server/templates 
.
I am confused why this just displays the last line?:

@when[#t]{
first
second
}

I including html only when a user is logged in, and my issue can be 
distilled to the above template syntax.

Happy to elaborate, thank!
