Is there a way to get DrRacket to indent all on save?

[Laurent.O]

Now that Quickscript has hooks (see here), it should be fairly easy to format as you wish:

From this script, just replace the line that removes trailing spaces with

       (define new-str (program-format str))

This requires Racket ≥v8.10.3 (which is in the snapshot for now). Let me know if that works — or not!
