Using Iteratees to write to a file
by Richard Wallace 19 Mar '11

19 Mar '11

Hello everyone, I've been reading "Iteratee: Teaching an Old Fold New Tricks" from the Monad Reader Issue 16 and am having a problem figuring out how to use the streamToFile function. Specifically, I can't figure out how to feed the Iteratee data to write to the file. If I run ghci> runIter $ streamToFile "/tmp/stream" Then the file is created but not populated with any data - which is natural since I didn't give it any data. I have no clue how to give it data though. I'd really appreciate it if someone could show me how to write "Hello world!" or something else equally mundane to get me going. I've been banging my head on this for hours now. Thanks, Rich

Getting Gtk2Hs working in windows
by Kyle Murphy 18 Mar '11

18 Mar '11

I'm trying to follow the instructions provided on http://www.haskell.org/haskellwiki/Gtk2Hs to install Gtk2Hs in Windows 7 (64 bit) and running into problems. Originally I was trying to get wxHaskell installed, but it kept crashing trying to build the monolithic library due to an apparent bug in the latest port of GCC, so after talking with some of the people in #haskell I was advised that Gtk2Hs was better supported and might be easier to get working. For the most part, that appears to be true but I (as well as several others it seems) am running into a problem where cabal can't seem to find quite a few of the Gtk+ libraries (specifically z, cairo, gobject, glib, and intl). Near as I can tell everything should be functioning, and running pkg-config --modversion glib-2.0 outputs "2.20.3" so at least pkg-config seems to be able to find glib. Looking in the Gtk+\lib\pkgconfig folder I see pc files for everything but z and intl listed. Running cabal install gtk2hs-buildtools also succeeds, it's only when I get to the cabal install gtk step that things fail. cmd console output for the usual environment variables: INCLUDE: C:\libxml\include;C:\Program Files (x86)\Gtk+\include LIB: C:\libxml\lib;C:\Program Files (x86)\Gtk+\lib PKG_CONFIG_PATH: C:\libxml\lib\pkgconfig;C:\Program Files (x86)\Gtk+\lib\pkgconfig I trimmed the PATH output below for everyones sanity.

Re: [Haskell-beginners] PHP vs Haskell... a challenge!
by Sean Charles 18 Mar '11

18 Mar '11

Thank you everybody for your responses, I am going to print them out and study them hard, particularly the use of left folds. I think I skipped that in RWH book... .I need to go back and re-cover the basic again I think... it's a tendency of mine to graze through stuff picking up what I need and sometimes you just can't beat learning the basics. As a still beginner after about eight months of (somewhat intermittent) usage I would say that in order to truly get to grips with Haskell as a concept let alone a language you need to know and understand ... * currying, which helped me to truly understand the signature notation used, a -> b -> c etc. I have used haXe, which is written in ocaml, and the notation is the same but now makes more sense! * function composition leading to point-less notation, this is better understood the currying penny has dropped * lazy versus strict evaluation and the concept of lazy I/O and why it can sometimes leave you scratching your head for a while!! LMAO! :) * monads: of course, for me the best video I've seen is this one. As a reluctant Drupal/PHP developer and wannabe FP developer for about six years now, each time I find myself coding some rubbish or other in PHP I have lots of 'ahah!' moments as I think that it would be nice to be able to express some idiom or form more succinctly in PHP and then I realise what X Y or Z is for in Haskell... that's the upside, the downside is I then have to continue the job in PHP! Thanks again, Sean.

Unit conversion
by Tom Murphy 17 Mar '11

17 Mar '11

Hi All, Is there a good way to easily convert between units? For example, let's say I have a data type: data Volumes = Teaspoon | Tablespoon | Slice | FluidOunces ... and I want to define an infix function '<+>', which adds together amounts of food: (1, Slice, cake) <+> (1, Volume Tablespoon, sugar) <+> (32, Volume FluidOunces, almondMilk) Which would return: (3200, Teaspoons) What is the most efficient way to define equivalency/conversion between these measures? I remember an interesting method for celsius-farenheit conversion in Higher-Order Perl, using function composition, but that was between only 2 units. I'd like something where I don't have to provide n^2 definitions. Thank you! Tom

Thanks to everyone for your explanations; and sorry about the group blunder ;) of course Brent is right, I should have said "R_+^*" plus multiplication. I will keep an eye on what the Haskell people do about Hierarchies of mathematical classes.

PHP vs Haskell... a challenge!
by Sean Charles 17 Mar '11

17 Mar '11

I tried in vain using Text.CSV to write a small utility for myself that would *simply* map a CSV file across a template, specifically for mass-producing Drupal nodes from a CSV file... Here's what the Haskell code has to compete with :- TESTDATA.CSV eric,42,"Hacker" bert,20,"Janitor" harry,15,"Web nerd" TEST.SQL UPDATE foo SET rating = @1, role = '@2' where name = '@0'; And the PHP code that is used to produce ANY output from the template and CSV data (forget injection attacks and all that for now, this is proof-of-concept remember)... <?php $template = file_get_contents($argv[1]); if ($fh=fopen($argv[2],"r")) { while($line = fgetcsv($fh)) { foreach ($line as $k => $v ) $line['@'.$k] = $v; echo strtr($template,$line)."\n"; } fclose($fh); } ?> Note that I have had to remap the index keys to @n in order not to accidentally hit any numerical data that may be in the template. This is my test, the *real* template creates a Drupal node dynamically and has lots of [0]['value'] bits in it so I had to do this, I will allow any shortcuts to be used though as I would have liked to have coded the utility in Haskell to get better at it but tonight it defeats me! Here then is my unsatisfactory code and no, it doesn't compile or work very well as I am still trying hard with it! I want to learn! Still my biggest headache is type matching and deciphering the sometimes complete gibberish output from the type inference system when I screw up... I am finding it very hard to work out what I did wrong at times. Sitting here with Real World Haskell is proving fruitless tonight. :( Here's the rubbish code... import Text.CSV import System.Environment import System.IO import Text.ParserCombinators.Parsec.Error main = do args <- getArgs case length args of 2 -> do csvdata <- parseCSVFromFile (last args) either (\error -> print error) (\csvdata -> processData (head args) csvdata) csvdata _ -> print "Usage: csvsql template datafile.csv (options later!)" {- csvdata is [CSV] a CSV is [Record] a Record is [Field] a Field is String -} processData :: String -> CSV -> IO () processData filename csvdata = do tin <- openFile filename ReadMode template <- hGetContents tin processRow template csvdata hClose tin return () processRow :: String -> [Record] -> String processRow template row = "eric" ++ template

overload a function
by Britt Anderson 16 Mar '11

16 Mar '11

I would like to have a function that can accept more than one input type and gives the same back as output. For the different eligible input types there would be different tests. An example of the idea would be something like: test :: a -> Bool -> a test 0 True = 0 test False True = False . . . is it obligatory that I create a typeclass for test and then instance each type that might go in the "a" slot? Because that seems like a lot of work. Let me also add a general thank to those of you who support the beginners' list. I learn something everyday.

Expressing the idea of a group in Haskell
by Christian 16 Mar '11

16 Mar '11

Hello Haskell-Experts! I was trying to express the notion of a (mathematical) group in Haskell, using type classes, as an exercise. If I am not mistaken, a group can be for example the Reals together with the multiplication operation and "1" as the neutral element. Or, the Reals with addition and "0". my first idea was to write something like class Group a where ... _but_, I thought, I need to parameterise, so to speak, not only using the type "a", but also the group operation. How could I do that in Haskell? Is that even possible? Thanks in advance! Christian

Cabal problems with System.hi
by Sean Charles 15 Mar '11

15 Mar '11

Somedays I feel so annoyed with software! Flushed with success from the HOpenGL tutorial on the wiki, having made it work, spotted a mistake in it (documented on the wiki) and 'made it my own' by adding bits and bobs, I decided to then add the capability to load a CSV file and visualise the data. So, here's how far I got ... import Text.CSV import System (getArgs) main = do args <- getArgs print $show args and here's what I got as output ... [1 of 1] Compiling Main ( csvsql.hs, csvsql.o ) $ ghc --make csvsql.hs csvsql.hs:2:0: Bad interface file: /home/sean/.cabal/lib/haskell98-1.1.0.0/ghc-6.12.3/System.hi Something is amiss; requested module haskell98:System differs from name found in the interface file haskell98-1.1.0.0:System WTF? How does a 'beginner' even begin to sort that out. I have searched in vain I am afraid. So I can do OpenGL but I can't even get that to build! Sheesh. It seems that every time I try to use something interesting, cabal won't build it. I've tried Snapp and happstack and they both fail with messages about array classes being less than or equal to or greater than some requested version etc etc. Sometimes I can't help feel that the whole thing is just a big bloody tangled mess. Today I even built something and got a warning about it 'better being fixed for 6.14' or else. Anybody ? Some details ... I am using the Haskell Platform on Ubuntu 10.10 ...
