[Haskell-cafe] Design question, HTML for GUIs?

2010-01-10 Thread Günther Schmidt

Hi everyone,

as probably most people I find the GUI part of any application to be the 
hardest part.


It just occurred to me that I *could* write my wxHaskell desktop 
application as a web app too.


When the app starts, a haskell web server start listening on localhost 
port 8080 for example and I fire up a browser to page localhost:8080 
without the user actually knowing too much about it.


Is that a totally stupid idea?
Which haskell web servers would make good candidates?
Are there any *continuation* based web server in haskell, something 
similar to Smalltalk's Seaside?

Is Hyena continuation-based?

No; Happstack. See Gitit for an example - it is a wiki, but people use
it locally all the time, such as myself or Don Stewart.

No, this is not (necessarily) a stupid idea. In fact it might be a good
idea in a lot of cases.

A downside is, that you lose the functionality for user access control
provided by the OS on multi-user machines (i.e., other users working on
the same machine can connect to localhost:8080 too). This might or might
not be a concern for you.

2010-01-10 Thread Michael Snoyman
I wrote a package to turn Hack applications into standalone apps using
Webkit. The code is available at
http://github.com/snoyberg/hack-handler-webkit. However, it's currently
Linux-only. However, if I was going to write a desktop app based on an HTML
GUI, I would bundle Webkit like this. It fixes such annoyances as I closed
the window but the program is still running.
