After I gave my Frog talk at RacketCon, in which I said a goal of Frog was to make it easy to install, J. Ian Johnson tried to install it... but couldn't.
As best I understand, it's because he was using Racket from HEAD, and at some point recently the `deps` expression for info.rkt changed for the case where you specify a version. A case which I've been using (recent versions of Frog need a >= version of Markdown). For 5.3.6 and (until fairly recently in HEAD) it was: # frog/info.rkt #lang setup/infotab (define version "0.7") (define collection 'multi) (define deps '(("markdown" "0.5") "rackjure")) But it recently changed to require a #:version keyword, therefore it would have to be IIUC this for 5.3.900.???+: # frog/info.rkt #lang setup/infotab (define version "0.7") (define collection 'multi) (define deps '(("markdown" #:version "0.5") "rackjure")) But that wouldn't be compatible with 5.3.6 IIUC. As a result I would have to maintain two different packages, one for 5.3.5 and 5.3.6, and another for 5.3.900.???+ and greater (yuck). Until now, even the major change to single-collection defaults was done in a way that preserved backward compatibility (well, after taking action to add `(define collection 'multi)`, but after taking such action the same info.rkt works for old and new). 1. Am I understanding it correctly? (Not a rhetorical question; I have a lot of "IIUC"s above.) 2. If so, is it really the intent to break backward compatibility? 3. Instead couldn't the #version keyword simply be optional? _________________________ Racket Developers list: http://lists.racket-lang.org/dev
