I know I can always hack around Scribble limitations. I can always do a trick that LaTeX users know: to create a named file that acts like a flag and use the InputIfFileExists LaTeX macro. But I always feel very dirty when I do that: I feel like I'm unable to communicate intent to my tools when I take back-channels like that. Conditional generation is a common use case. In particular, the use case I'm considering directly affects the Bootstrap curriculum work I'm doing in the summer: we need to generate documentation for both students and teachers, and we'd really like to use the same source file. As such, I'd really like a good way to set up parameterizations in a way that's directly supported by the Scribble command line tool. The scribble tool is hardcoded to set up certain parameterizations, such as current-render-mixin, through its command line arguments. I'd like that facility to be open to extension. _________________________ Racket Developers list: http://lists.racket-lang.org/dev
