RacketUI - Automated Web UI Generator for Racket
================================================
RacketUI is intended to be a teachpack to provide facilities for the
quick and easy generation of web interfaces for programs written in
the HtDP (_How to Design Programs_) languages of Racket (see
docs.racket-lang.org).
Example
-------
Consider the following program, which builds an acronym from the
capitalized words in a list of strings (comments and test cases are
omitted):
(define (acronym a-los)
(cond [(empty? a-los) ""]
[(cons? a-los) (cond
[(string-upper-case? (string-ith (first a-los) 0))
(string-append (string-ith (first a-los) 0)
(acronym (rest a-los)))]
[else (acronym (rest a-los))])]))
A web application for this can be automatically generated using:
(require (planet nah22/racketui/web-launch))
(web-launch
"Acronym Builder"
(function "Produces an acronym of the capitalized words in the given list."
(acronym ["Words" (listof+ ["Word" string+])]
->["The acronym" string])))
Running this program should launch a web browser with an user
interface allowing input of a list of words (strings) and the
ability to apply the function to that input to view the result.
