and finally i noticed

“example only works with old version of formlets”
above.

all published (non-experimental), especially didactic code always working is in my dreams

sorry for spam but obvious miskake

all the best – great blog

Hmm
in case anyone reads the above before tupil i’d better point out it
seems i’ve managed to download a main.lhs as well as a Main.hs. That doesn’t have the includes but lots of out of scope msgs.

hi chris,

jolly helpful in trying to understand Applicative.

unfortunately

i get a currently inaccessible hpaste.org as the only mention of Paths_hackage_server

and no Distribution.Server or Distribution.Text in HAppS-Server or hoogle that i can find.

cheers

jim

Anon: there are two functions that might be handy for you: xml and plug. The xml function just builds a unit formlet with raw xml. The plug function modifies the xml of a formet. It takes a function of type “xml -> xml1″, but xml1 could of course also be xml.

The formlet package does not appear to have a label function like the one mentioned above. Is there code for this anywhere? Or maybe a more generic formlet function that allows you to add arbitrary text to the HTML generated by a formlet?

Nice! I definitely need to read up on Applicative. It wasn’t in Utrecht’s Advanced Functional Programming course of 2006-2007 but hardly a year later it seems everyone is using it.

Sjoerd: you can easily add other html to the formlets. For example, adding a label can be done like this:

userFull = User <$> label "Name: "    *> inputF    Nothing 
                <*> label "Password " *> passwordF Nothing 
                <*> label "Date: "    *> dateFull

The *> combinator throws away the result of its argument. So label “Test” *> inputF Nothing will still have type FailingForm String.

How do you solve stylability? Certainly when it comes to complex widgets like calender widgets this becomes hairy.

Layout of labels and error messages is also always tricky to get right generically.
