For HtDP/2e, I use plain old conditionals and variables. I used to set an environment variable when I ran a shell script. Then I converted everything to Racket and set variables according to shell arguments:
$ ./xhtml draft creates the draft version of HtDP/2e by setting a *draft variable to #t and in other places I simply write @(if *draft "Draft" "Release") and such. -- Matthias On Apr 25, 2012, at 3:58 PM, Danny Yoo wrote: > I'm working on building a Scribble extension that lets me write > conditional bits of Scribble code. > > Some use cases: 1. writing a document that can be author-anonymized > 2. tutorial material, with solutions to be generated in the document > targetted for teachers. > > I do not want to hide or show content with styles: it's too easy to do > "View Source" on an HTML document.
