问题 I use compiled Heist. My splices only do run-time work (no load-time work). I have a template.tpl like this: <html> <head> <title><titleSplice/></title> </head> <body> <bodySplice/> </body> </html> This is how I do things: Within the Snap action for a /:param route, I use renderTemplate heistState "template" to obtain a MyHeistRuntimeMonad Builder . I can pass the :param value to my splice by putting it into my runtime monad via ReaderT: type MyHeistRuntimeMonad = ReaderT String IO . (Where

问题 I'm working on porting a site from PHP to Snap w/ Heist. I've ported some of the simpler forms to using Digestive Functors successfully, but now I have to do the tricky ones that require the use of subforms. This application manages producing flyers for retail stores, so one of the tasks that need to be done is adding an ad size and defining its physical dimensions on the printed flyer. Sizes will vary depending on the type of page (configurable by the flyer owner) and its orientation (which

问题 I think I did asked a similar question some time ago but it was not answered due to unstable API. So I was waiting for the 0.13 to pass by. I am not sure if it is correct to bring up a similar question...? What is the alternative to interpreted runChildrenWith(Text) and mapSplices in the compiled splices world? (this combination seems to be the most common) I would really appreciate some code examples if possible. If I understand correctly, we get together all the application splices and then

问题 I have used writeBS writeText from Snap and renderTemplate from heist but none of them seems to support unicode. site :: Snap () site = do ifTop (writeBS "你好世界") <|> route [("test", testSnap)] testSnap :: Snap () testSnap = do fromJust $ C.renderTemplate hs "test" -- test.tpl 你好世界 I expected it to output "你好世界" for the / or /test route, but in fact its output is just some messy code. 回答1: The problem here is not with writeBS or writeText. It's with the conversion used by the OverloadedStrings
