Simple web-related functions (1)

We will here give a simple example of a web-related function. Much more interesting examples will appear later in the material.

(define (www-document the-title . body-forms)
 (html
  (head (title the-title))
  (body body-forms)))

The definition of a www-document function. The www-document function is useful if you want to abstract the HTML envelope formed by the elements html, head, title, and body. If you need to pass attributes to html or body the proposed function is not adequate.

A sample application of the function www-document.

Notice the way we pass a number of body contributions, which - as a list - are bound to the formal parameter body-forms.

The whole story - including the LAML context.
