10 Web Page Tools

(require (planet cce/scheme:4:1/web))

This module provides tools for programmatic creation of static web pages. It is based on the XML collection; see documentation for xexpr?.

css/c : flat-contract?

(css? v) → boolean?   v : any/c

This contract and predicate pair recognizes CSS-expressions, which are described by the following grammar:

css		=		(list style ...)
style-def		=		(cons selector (list property ...))
property		=		(list name value)
selector		=		text
name		=		text
value		=		text

Here, text is any of the Text Representations described above.

xexpr/c : flat-contract?

This flat contract corresponds to xexpr?.

(write-css css [out]) → void?   css : css/c   out : output-port? = (current-output-port)

(write-xexpr css [out]) → void?   css : css/c   out : output-port? = (current-output-port)

These functions write CSS-expressions and X-expressions, respectively, to output ports, by their canonical text representations.

(create-stylesheet file css) → void?   file : path-string?   css : css/c

(create-webpage file xexpr) → void?   file : path-string?   xexpr : xexpr/c

These functions write style sheets (represented as CSS-expressions) or webpages (represented as X-expressions) to files.
