Documentation is gravely lacking.} The @bold{html-template} package implements an HTML-writing template language based on @link["http://www.neilvandyke.org/racket-xexp/"]{SXML/@emph{xexp}}. Compared to doing comparable work using the @link["http://www.neilvandyke.org/racket-html-writing/"]{html-writing} package, @bold{html-template} offers improved compile-time error-checking and improved run-time efficiency. !!! For example: @SCHEMEBLOCK[ (define (write-essay my-title) (html-template (html (head (title (%eval my-title))) (body (h1 (%eval my-title)) (p "Kittens claw." (br) "Puppies pee."))))) (write-essay "All About Kittens & Puppies") ] produces the output: @verbatim["All About Kittens &\nPuppies

All About\nKittens & Puppies

Puppies pee.

"] !!! Expanding the @tt{html-template} macro in this case results in something like: @SCHEMEBLOCK[ (define (write-essay my-title) (display "") (write-html my-title) (display "

") (write-html my-title) (display "

Kittens claw.
Puppies pee.

")) ] Note that much of the computation for HTML formatting is done at compile time rather than at run time. !!! @section{Interface} !!! @defproc[ (html-template (xexp any/c) (... any/c)) any/c]{ !!! } @defproc[ (html-template/port (port any/c) (xexp any/c) (... any/c)) any/c]{ Behaves as @tt{html-template}, with the addition that the @tt{current-output-port} parameter set to @schemevarfont{port} by @tt{parameterize} for the duration, including for run-time evaluations as a result of @tt{%eval/effects-only} and @tt{%eval} forms. } @defproc[ (html-template-to-string (xexp any/c) (... any/c)) any/c]{ !!! } @section{Debugging} @defproc[ (html-template-debug-expand (xexp any/c) (... any/c)) any/c]{ !!! } @section{History} @itemize[ @item{Version 0.1 --- 2011-08-21 -- PLaneT @tt{(1 0)} } ] @section[#:tag "Legal"]{Legal} Copyright (c) 2011 Neil Van Dyke.
