Bob___ Well, if you look you see that 'diff' is in the Generic module; that is, diff can be defined using the basic operators provided by the backend. In this case, you 'diff' two versions by retrieving a specific revision, storing it, and then retrieving the other specific revision, storing it, and then filestore calls the Diff package on the two Strings. Nothing stops you from copying this approach and adding in a parsing step and then passing it to a custom diff - as long as the backend supplies 'retrieve', you're good. -- gwern ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

All announcements should go to hask...@haskell.org if nowhere else. In practice, it is probably best to post to both haskell and haskell-cafe and this is what most people do. I would suggest that posting announcements *only* to haskell@, but with followups set to haskell-cafe@, is the ideal way to keep everyone informed, whilst minimising the amount of unnecessary duplicate mails people receive. (And on the topic of duplicate mails, it would reduce _so_ much irritation if all the haskell-related mailing lists could set the Reply-To header to the list, instead of defaulting to the original poster. I already have enough email to deal with without having 3 or sometimes 4 copies of every message in every thread that I participate in.)

The duplicate messages will have the same Message-ID, can't your email client hide the duplicates for you? You might have to enable an option or something? I am pretty sure Reply-to munging has been discussed on this list before (mostly because it will eventually be discussed on every mailing list). The usual consent is that many people hate it, it violates the standards set by the IETF, it results in people accidently sending private messages to the list. I think one reason why people don't like Reply-to munging is that many people filter the haskell-cafe mailing list into a separate folder that they only read occasionally. So, if they post a message they *want* the reply to go to their main inbox as well as the mailing list folder. Otherwise they would have to keep checking the mailing list folder to see if they had any replies, instead of just checking their inbox. I believe there are two solutions to your problem: 1. set the Reply-to header yourself to specify how you want people to reply to messages you post. If you only want them to do to the list, then set that. Some email clients can be configured to do this automatically when posting to specific mailing lists. 2. use (or configure) a mail client that can hide duplicate messages. http://www.unicom.com/pw/reply-to-harmful.html http://woozle.org/~neale/papers/reply-to-still-harmful.html -j ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
