There are still prizes.

It is easy and fun.

Make DrRacket do what *you* want.

Hi All,

The example in the documentation is bad - it redefines 'reverse' (which is fine), then attempts to use it.

The working version changes the name of the script (which is just a function) to 'reverse-selection' so it doesn't cause the error:

(define-script reverse-selection
  #:label "Reverse"
  (λ (selection)
    (list->string (reverse (string->list selection)))))

I still think making scripts is easy and fun but I apologise for not testing the documentation.

here is a script I just made (and tested);

#lang racket/base

;;; License: MIT/Apache2.0

(require browser/external

quickscript)

(script-help-string "Racket Survey.")

(define-script racket-survey

#:label "Racket Survey (browser)"

#:menu-path ("&News")

#:help-string "Complete the Racket Survey now"

(λ (str)

#f))

click new script in the menu and give it a name 'survey' this will create a file 'survey.rkt' in the user scripts folder

paste in the above, save and click 'compile scripts and reload'.

- you will find the script "Racket Survey (browser)" under 'News' in the scripts menu.

There is still time to enter and prizes to be won.

Stephen
