04:58 < dibblego> is the HAppS tutorial2 out of date?
06:15 < HugoDaniel> back
06:15 < HugoDaniel> sorry
06:15 < HugoDaniel> yes, im using freebsd
06:15 < HugoDaniel> i used screen to pump up happstack as daemon
06:15 < HugoDaniel> everything went fine
06:16 < HugoDaniel> i really like the xmonad feature of dynamic compilation, it would be great to have it in happstack
06:16 < HugoDaniel> or in a higher level app
06:16 < HugoDaniel> so users only needed to change a config file, and "reload" the runing server
06:26 < HugoDaniel> dyre comes to mind http://hackage.haskell.org/package/dyre
08:43 < HugoDaniel> http://serv.fcsh.unl.pt/a3es/   user: 777 pass: 1777
08:43 < HugoDaniel> all in haskell/happstack/postgresql ... im still finishing it out
08:44 < koeien> are you using happstack-state?
08:44 < koeien> or only a SQL database?
09:36 < HugoDaniel> only sql
09:36 < HugoDaniel> done in about a week
09:36 < HugoDaniel> without prior knowledge of happstack and plpgsql, i guess i could do it a lot faster now...
09:37 < koeien37> what is plpgsql ?
09:37 < HugoDaniel> is the language for the stored procedures of postgresql
09:37 < koeien37> ah. yes
09:37 < koeien37> well, good to hear that it worked out for you
09:37  * koeien37 is a little scared of happstack-state still :)
09:37 < HugoDaniel> the user that happstack uses to access the database has only execute permissions over the database
09:38 < HugoDaniel> it can't do selects, and it can't do inserts/updates
09:38 < koeien37> yeah, i've seen you talk about that before. I think that's pretty sound design
09:38 < HugoDaniel> only execute stored procedures
09:38 < koeien37> i use django atm. i'm a huge fan of everything of it, except the python
09:38 < HugoDaniel> i would like to automate this kind of workflow, perhaps with template haskell
09:38 < HugoDaniel> eheh
09:38 < HugoDaniel> i used to work with django too
09:38 < HugoDaniel> i really like the way they map actions
09:38 < HugoDaniel> using regex
09:39 < koeien37> yes
09:39 < koeien37> although happstack also seems quite nice in that regard
09:39 < koeien37> but i haven't really used it yet :P
09:39 < koeien37> maybe i should find some toy project to complete
10:15 < stepcut> HugoDaniel: there is some code in happstack which will watch the project directory, and automatically recompile and retart the server when the code changes I think..
10:17 < stepcut> HugoDaniel: we used to have support for dynamically recompiling and loading templates with out restarting the server processes, but the plugins library does not work with GHC 6.10 or higher. http://code.google.com/p/happstack/issues/detail?id=20
10:18 < stepcut> I know how the new version should work, but I don't have the time to implement it :-/
10:20 < HugoDaniel> hmm
10:20 < HugoDaniel> but the templates already reload in every refresh
10:20 < HugoDaniel> without restarting the server
10:22 < stepcut> HugoDaniel: depends on what templates you are talking about..
10:23 < stepcut> HugoDaniel: we used to have support for 'templates' that were arbitrary Haskell code
10:24 < stepcut> so the templates had to be compiled with GHC
10:24 < HugoDaniel> ah
10:24 < HugoDaniel> im talking about hstringtemplate templates
10:24 < HugoDaniel> :)
10:24 < stepcut> but, the idea could be extended beyond just templates -- you could make whole serverparts dynamically reloadable
11:22 < HugoDaniel> yes
11:22 < HugoDaniel> that seems like a good thing
11:42 < HugoDaniel> i really like bsd style configs
11:42 < HugoDaniel> simple text files, that override the defaults
11:55 < stepcut> i really like Haskell file configs
11:59 < HugoDaniel> they are nice, but humans tend to be horrible syntax parsers
11:59 < HugoDaniel> specially when confronted with a new syntax
12:04 < stepcut> HugoDaniel: that's why using a syntax I already know, and which can be parsed and type checked is so great
12:05 < stepcut> .ini-style files are the devil -- there is no true standard for them. I know, I have tried to write parsers for them :)
12:06 < HugoDaniel> :D
12:11 < koeien37> stepcut: agreed, as long as i get a sane error message, and not "read: failed"
12:12 < HugoDaniel> read: no parse
12:12 < HugoDaniel> is also nice
12:12 < HugoDaniel> but thats user work
12:12 < HugoDaniel> not so much happstack related
12:18 < stepcut> koeien37: :)
12:30 < xkb> hi
12:31 < xkb> I'm still having troubles installing happs-tutorial
12:31 < xkb> on my mac, HStringTemplate depends on mtl-1.1.0.2 and fails on that
12:31 < xkb> even though it is installed
12:31 < xkb> the err msg:
12:31 < xkb> Text/StringTemplate/QQ.hs:24:7:
12:31 < xkb>     Could not find module `Control.Monad.Writer':
12:31 < xkb>       it is a member of the hidden package `mtl-1.1.0.2'
12:31 < xkb>       Use -v to see a list of the files searched for.
12:32 < vowyer> isn't it hidden?
12:32 < vowyer> you could add the dependency in cabal file
12:32 < xkb> I tried expose, to no avail
12:32 < xkb> ah
12:32 < xkb> I could try that
12:33 < stepcut> hstringtemplate should already be installed when you install happstack, yes?
12:33 < xkb> yes, it is a higher version
12:34 < stepcut> happs-tutorial requires an earlier version?
12:34 < xkb> * HStringTemplate
12:34 < xkb>     Synopsis: StringTemplate implementation in Haskell.
12:34 < xkb>     Latest version available: 0.6.2
12:34 < xkb>     Latest version installed: 0.6.2
12:34 < xkb> yes, it says 0.5
12:34 < vowyer> change it to use 0.6 and see if it compiles
12:35 < vowyer> mine is 0.4.3, strange :S
12:36 < xkb> HStringTemplate >= 0.4.0 && < 0.5.0
12:36 < xkb> is in the cabal file
12:36 < vowyer> that doesn't mean it's incompatible with >= 0.6
12:37 < xkb> trying now
12:38 < stepcut> xkb: where did you get your version of happstack-tutorial from?
12:38 < stepcut> xkb: and what version is it?
12:38 < xkb> just regular cabal update/cabal install
12:39 < stepcut> k
12:39 < xkb> 0.9.3
12:40 < xkb> hmm odd
12:40 < xkb> configure went ok
12:40 < xkb> build fails on the same dependency
12:40 < xkb> HStringTemplate-0.5
12:40 < xkb> even though I changed the dep in the cabal file
12:41 < stepcut> odd
12:41 < stepcut> gotta run
12:41 < xkb> It uses the cabal file in the unpacked dir right?
12:42 < stepcut> yes
12:42 < xkb> hmm strange
12:42 < xkb> thanks for the help anyway :)
12:42 < stepcut> well, depending on how you call cabal
12:42 < stepcut> if you do, cabal install, in the unpacked directory it will use the local directory
12:42 < xkb> just from $PATH
12:42 < vowyer> it uses /tmp in my config for building
12:42 < stepcut> if you did, cabal install happs-tutorial, then it might still get everything from the server
12:42 < xkb> ill try from unpacked dir
12:43 < xkb> ah
12:43 < xkb> now I got another error. Typecheck
12:44 < xkb> that's the same I had yesterday
12:44 < xkb> smartserver
12:44 < xkb>            (Conf 5001 Nothing)
12:44 < xkb>            "happs-tutorial"
12:44 < xkb>            (controller tDirGroups True True)
12:44 < xkb>            stateProxy
12:44 < xkb> ]
12:44 < xkb> Couldn't match expected type `ServerPartT IO a'
12:44 < xkb>            against inferred type `[Char]'
12:44 < xkb> so it expects another signature
12:44 < xkb> no string app.
12:45 < vowyer> well, you are making progress :)
12:46 < xkb> lol :)
12:46 < xkb> maybe I should just build happstack myself :)
12:46 < vowyer> I haven't tried the tutorial yet, I briefly looked at the guestbook sample and it's pretty clear
12:47 < xkb> I wanted to try the Real World Happstack during the holidays
12:47 < xkb> but I can just try to hack somehting myself :)
12:48 < vowyer> why not?
12:48 < xkb> prob. learn more that way I guess
12:48 < vowyer> tweak the demo a bit, a simple blog shouldn't be too difficult
12:49 < xkb> wanted to try something twitter-integration like
12:49 < vowyer> happstack new project my-twitter-killer, for exampl
12:49 < xkb> I dont know if there's a twit-lib yet?
12:49 < xkb> htwitsome or something ;-)
12:50 < vowyer> there has to be at least 1
12:50 < xkb> hehe, should be yeah
12:50 < xkb> it's so popular these days
12:50  * koeien37 doesn't see the point of Twitter
12:51 < xkb> I use it as RSS, without the reader ;-)
12:51 < HugoDaniel> twitter is great
12:51 < HugoDaniel> :D
12:51 < HugoDaniel> to pass around crazy links
12:51 < vowyer> I see the point, but not the need
12:51  * stepcut reads twitter via an RSS reader ;)
12:51 < xkb> lol
13:06 < koeien37> i briefly looked at UHC to see if i could add a javascript back-end, but no luck so far :(
14:37 < stepcut> xkb: recent versions of happstack-helpers have removed the String argument to smartserver
14:37 < stepcut> if you remove that argument it should build
17:08 < xkb> stepcut: thanks for the pointer, trying it out now
17:13 < xkb> nice! that did the trick
17:13 < xkb> cool thanks!
17:13 < stepcut> cool,
17:13 < stepcut> out for beer, bbl
