[Haskell-cafe] EDSL's using Filet-O-Fish of Barrelfish project

Hi All, I'd been looking for a mechanism to generate "C" from Haskell as EDSL - to develop an OS. In the process, I ran into the Barrelfish project ( http://www.barrelfish.org) - They seem to be using Haskell based "DSL generator" called Filet-O-Fish - http://www.barrelfish.org/fof_plos09.pdf It w

Thank you all very much, I am sitting now and collating all your responses. I'll revert with questions if I may have. Indeed, it may be better to have this kind of collateral ready for future use. I am going to put my stuff on github considering markdown + pandoc. Regards, Kashyap On Sat,

[Haskell-cafe] An attempt at an EDSL for platform independent 3D animation

Hi All, I've written a Haskell program that allows you to describe "dance movements" and it spits out javascript that does animation on an HTML 5 canvas (that's the platform independent bit). https://github.com/ckkashyap/Dancer Please do check it out and let me know what you think - all you'd ne

[Haskell-cafe] OpenShift a free PaaS from RedHat

Hi Folks, I just found out about OpenShift - its a free PaaS from RedHat. It has some interesting offerings. It does not support Haskell out of the box as of now. Please do check it out and if you like it - vote for Haskell support on it here - https://openshift.redhat.com/community/content/suppor

Re: [Haskell-cafe] OpenShift a free PaaS from RedHat

Thank you Micheal and Satvik. I think cde should solve the problem - I'll confirm later - for some reason, I do not have SSH connectivity from my office. What'll be best though is - yesod on OpenShift :) Regards, Kashyap On Fri, Jul 6, 2012 at 10:51 AM, satvik chauhan wrote: > >> OpenShift give

[Haskell-cafe] Non-greedy match in Text.Regx.Posix

[Haskell-cafe] Need help with learning Parsec

Dear gentle Haskellers, I was trying to whet my Haskell by trying out Parsec today to try and parse out XML. Here's the code I cam up with - I wanted some help with the "gettext" parser that I've written. I had to do a dummy "char ' ') in there just to satisfy the "many" used in the xml parser.

[Haskell-cafe] Capturing the parent element as I parse XML using parsec

Hi, With the help of the cafe I've been able to write up the xml parser using parsec - https://github.com/ckkashyap/really-simple-xml-parser/blob/master/RSXP.hs I am struggling with an idea though - How can I capture the parent element of each element as I parse? Is it possible or would I have to

[Haskell-cafe] Current state of garbage collection in Haskell

Hi, I was looking at a video that talks about GC pauses. That got me curious about the current state of GC in Haskell - say ghc 7.4.1. Would it suffer from lengthy pauses when we talk about memory in the range of 500M +? What would be a good way to keep abreast with the progress on haskell GC? Rega
