  What's up with the rendering of html on said site: ><head ><meta http-equiv="Content-Type" content="text/html; charset=UTF-8" ><link rel="stylesheet" type="text/css" href="/theme/default.css" ><title >Happstack - Frequently Asked Questions</title ></head ><body Is the reason for this behavior to make markup like: a <a href="#"> link </a> . to render as "a link." in stead of "a link ."? Either way, it looks awful.

    It prevents spurious whitespace from showing up in text nodes.

I'm glad to see a haskell web framework. I'd be very happy to use Haskell rather than Python. But, why pair Happstack with Macid, some haskell serialization format that appears to not work very well? http://tutorial.happstack.com/tutorial/why-happstack-is-cool http://tutorial.happstack.com/tutorial/why-happstack-is-cool http://tutorial.happstack.com/tutorial/macid-stress-test http://tutorial.happstack.com/tutorial/macid-stress-test It's not a major issue, since it looks like you don't need to use it. However, once Happstack gets a few batteries included (e.g., authentication), I don't want them to be tied to Macid.

  you're not locked in to using Happstack's state management system, MACID, for everything.
  - yummyfajitas 16y ago
    I realize that. What I said: "It's not a major issue, since it looks like you don't need to use it." My issue with MACID is that when Happstack starts including features like authentication, I don't want them to be tied to MACID.

XKCD is powered by Happstack - http://dynamic.xkcd.com/comic/random http://dynamic.xkcd.com/comic/random Back when I submitted http://news.ycombinator.com/item?id=1186025 http://news.ycombinator.com/item?id=1186025, you could insert any path any level deep inside dynamic.xkcd.com and it'd take you to a random comic - looks like that's changed now :-|

This is very cool, and it brings a question to mind: I've been using GWT a lot lately, and thought to google around to see if anybody had done a Haskell-to-JavaScript compiler: http://haskell.org/haskellwiki/Yhc/Javascript/Programmers_guide http://haskell.org/haskellwiki/Yhc/Javascript/Programmers_gu... While GWT is independent of what you have on the back-end, a lot of good comes from being able to use java objects as shared currency between the client & server over the RPC mechanism. So, as an OO practitioner who is curious about better languages, I have a question: If one were to have haskell on the server side, and haskell as a source language on the client side, how would an RPC mechanism look for communicating between the two? In GWT, the object serialization and Command Pattern works very nicely. What would you do in the purely functional world?

  Ocaml has ocamljs and orpc: http://code.google.com/p/ocamljs/ http://code.google.com/p/ocamljs/ Haskell has a couple of haskell->js compilers but I'm not aware of any rpc mechanisms. Clojure has clojurescipt: http://github.com/richhickey/clojure-contrib/tree/master/clojurescript/ http://github.com/richhickey/clojure-contrib/tree/master/clo... Presumably rpc would be easy given the mostly uniform data representation.

    Also check out Nitrogen which is an interesting approach to the problem: http://nitrogenproject.com/ http://nitrogenproject.com/

Is there anything that actually explains what it is and does? What exactly is MACID? Can I swap in my own preferred DB? What does it use for templating? Do I have a choice of template tools? Does it work with Hack? Can I add in middleware?
