Snap: compiled splices code example

由 こ雲淡風輕ζ 提交于 2019-12-04 11:26:26
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 add them to the heistInit . Can anyone show how to do it please? Does the splice binding tag has to be

Installing Haskell packages on Mac

由 对着背影说爱祢 提交于 2019-12-03 05:36:38
问题 I can't seem to get a few Haskell packages to install on my Mac (10.6.8). I first tried Happstack and it failed and then I tried Snap. Sometimes when I run ghci I get a segmentation fault.

Loading package base ... linking ... done. Prelude> When trying to get Snap: .... .... .... Loading package

问题 I've installed Snap/Haskell on my production Ubuntu server (on EC2), and checked-out my project - but how do I run it? I mean, locally, I run it from command line: project-name -p 8000 Does snap come with it's own web-server (it looks like it), and if so how do I go about configuring it to run as a daemon of some sort? Any tips? Edit 2: On the wiki they say: snap-server is an HTTP server library that supports the interface defined in snap-core. While here, the haskell wiki about "Deployment

How to show utf8 text with snap and heist?

由 半城伤御伤魂 提交于 2019-11-30 09:58:50
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

Comparing Haskell's Snap and Yesod web frameworks

由 被刻印的时光 ゝ 提交于 2019-11-27 09:56:57
The two Haskell web frameworks in the news recently are Yesod (at 0.8) and Snap (at 0.4). It's quite obvious that Yesod currently supports a lot more features than Snap. However, I can't stand the syntax Yesod uses for its HTML, CSS and Javascript. So, I'd like to understand what I'd be missing if I went with Snap instead. For example, doesn't look like database support is there. How about sessions? Other features? mightybyte Full disclosure: I'm one of the lead developers of Snap. First of all, let's talk about what Snap is. Right now the Snap team maintains five different projects on hackage
