[Haskell-cafe] Lambdabot plugin system description

2011-07-01 Thread Richard Wallace
Hey all, I'm curious if there are any papers or anything else describing the plugin system in Lambdabot. If not I'll dig through the code, but my Haskell isn't yet that strong so a higher level introduction would be very helpful. Thanks, Rich ___

[Haskell-cafe] External system connections

2011-07-10 Thread Richard Wallace
Hello all, I'm trying to understand how to properly structure a connection to an external system. I'm writing an application that processes requests (it's an IRC bot - ya, I've looked at lambabot but it's a bit beyond my current understanding and I'm really trying to learn this stuff and find

Alright, I'll have to think on this some more but I think we're speaking the same language now - and what's more I even understand it! Thanks again for all your help, Rich On Sun, Jul 10, 2011 at 6:46 PM, Brandon Allbery allber...@gmail.com wrote: On Sun, Jul 10, 2011 at 20:19, Richard Wallace

[Haskell-cafe] Is ListT a valid MonadPlus?

2012-02-08 Thread Richard Wallace
It appears to me that the MonadPlus instance for ListT breaks the following MonadPlus law m mzero = mzero I've tried with every implementation of ListT I could find - the one in mtl, transformers, List, even ListT done right and it's alternative. They all seem to violate the above law.

Re: [Haskell-cafe] hellno - a somewhat different approach to tackling cabal hell

2012-09-02 Thread Richard Wallace
I like the approach so far. But hellno itself seems to have several dependencies itself. So installing with cabal pulls these in as fixed libraries (text, mtl, transformers, and parsec). Any plans to make these not have to be fixed? Or is there a trick I'm missing? On Sun, Sep 2, 2012 at 11:25

[Haskell-cafe] Getting started with Shake

2012-09-23 Thread Richard Wallace
Hey all, I'm going to be working on a webapp in Haskell in the upcoming months and am thinking Shake would be a good fit - I'll need to do js, css, and probably some graphics processing as part of the build and would like to use Shake to automate deployment. I'm not entirely sure how to get

[Haskell-cafe] acid-state audit trail

2012-10-18 Thread Richard Wallace
Hey all, I've been looking at acid-state as a possible storage backend for an application. It looks like it fits my needs pretty damn well, but one thing that I'm curious about is if it is possible to get a list of update events. You can obviously query for the current state, but it's not

the archive yourself. the checkpointing just reduces the recovery time (i.e creates a fixed point in time), if you were to keep all the checkpoint/archives then you would have the complete history Neil On 19 Oct 2012, at 06:18, Richard Wallace rwall...@thewallacepack.net wrote: Hey all, I've

In case you haven't seen it, there is an intro to Haskell video series by Erik Meijer on Channel9. There aren't any graded assignments or anything like that, but I found it to be excellent without those. [1]
