ANN: template 0.1 - Simple string substitution
by Johan Tibell 23 Apr '07

23 Apr '07

As an exercise I wrote a simple string substitution library that supports "$"-based substitution ala Perl or Python. Example usage: > import qualified Data.ByteString.Lazy.Char8 as B > import Text.Template > > context = Map.fromList . map packPair > where packPair (x, y) = (B.pack x, B.pack y) > > helloTemplate = B.pack "Hello, $name! Want some ${fruit}s?" > helloContext = context [("name", "Johan"), ("fruit", "banana")] > > main = B.putStrLn $ substitute helloTemplate helloContext Hopefully this is useful for someone who needs something more readable than Text.Printf's "%s"-based substitution or string concatenation for longer strings but less than a full blown templating system like the ones found in most web frameworks. Release: http://www.johantibell.com/template/template-0.1.tar.gz Source: darcs get http://darcs.johantibell.com/template Once we get ByteString literals most of the noise in the above example will disappear. In the mean time it's probably a good idea to write utility function like "context" above when you prefer a convenient String interface to a somewhat faster ByteString interface. It would be great if someone could do a code review and add it to Hackage if it looks OK. I'll really appreciate the feedback. Also, I'm not 100% sure how to make the haddock links work with Hackage so they link to the library docs. Is this something done at upload time? Here are some open issues: * I currently use my own ByteString parser. Data.Binary almost does what I need. Basically I need takeWhile and two chars of look-ahead. * I would like to only depend on base, currently I use State so I depend on mtl. Cheers, Johan

ANNOUNCE: xmonad 0.1
by Spencer Janssen 22 Apr '07

22 Apr '07

The xmonad dev team is pleased to announce the inaugural release of: xmonad: a tiling window manager http://xmonad.org Xmonad is a minimalist tiling window manager for X, written in Haskell. Windows are managed using automatic layout algorithms, which can be dynamically reconfigured. At any time windows are arranged so as to maximise the use of screen real estate. All features of the window manager are accessible purely from the keyboard: a mouse is entirely optional. Xmonad is configured in Haskell, and custom layout algorithms may be implemented by the user in config files. A principle of Xmonad is predictability: the user should know in advance precisely the window arrangement that will result from any action. By default xmonad provides three layout algorithms: tall, wide and fullscreen. In tall or wide mode, windows are tiled and arranged to prevent overlap and maximise screen use. Sets of windows are grouped together on virtual screens, and each screen retains its own layout, which may be reconfigured dynamically. Multiple physical monitors are supported via Xinerama, allowing simultaneous display of a number of screens. By utilising the expressivity of a modern functional language with a rich static type system, Xmonad provides a complete, featureful window manager in less than 500 lines of code, with an emphasis on correctness and robustness. Internal properties of the window manager are checked using a combination of static guarantees provided by the type system, and type-based automated testing. A benefit of this is that the code is simple to understand, and easy to modify. More information, screenshots, documentation and community resources are available from: http://xmonad.org Xmonad is available from hackage, and via darcs. Happy hacking!

Vacancy for a PhD student
by Johan Jeuring 20 Apr '07

20 Apr '07

(Knowledge of Haskell is a big plus; implementation of most of the tools will be done in Haskell.) Vacancy: PhD student in the Strategy Feedback project 1+3 years, Open University the Netherlands, location: Heerlen (preference). The project: In many subjects students have to acquire procedural skills. Problems in mathematics are often solved using a standard procedure, such as for example solving a system of linear equations by subtracting equations from top to bottom, and then substituting variables from bottom to top. Problems in computer science, physics, chemistry, electrotechnics, and other subjects, often require procedural skills as well. Furthermore, procedural skills appear at any educational level. E-learning systems offer excellent possibilities for practicing procedural skills. The first explanations and motivation for a procedure that solves a particular kind of problems are probably best taught in a class room, or studied in a book, but the subsequent practice can often be done behind a computer. There exist many e-learning systems or intelligent tutoring systems that support practicing procedural skills. The tools vary widely in breadth, depth, user-interface, etc, but, unfortunately, almost all of them lack sophisticated techniques for providing immediate feedback. If feedback mechanisms are present, they are hard coded in the tools, often even with the exercises. This situation hampers the usage of e-learning systems for practicing procedural skills. This project aims to investigate techniques for providing flexible and immediate feedback in tools that support practicing procedural skills. We want to use advanced techniques from computer science, taken from fields such as term rewriting, strategies, error-correcting parsers, and generic programming to provide feedback at each intermediate step from the start towards the solution of an exercise. We want to further develop some of these techniques, and apply and experiment with them in the domain of e-learning systems. Our goal is to obtain e-learning systems that give immediate and useful feedback. We will cooperate on this project with the Software Technology group from Utrecht University. Requirements: University degree in Computer Science. Good knowledge of functional programming, and several advanced computer science techniques. Knowledge of parsing, rewriting, strategies, generic programming, etc. will be useful. More information about the project can be found on http://ideas.cs.uu.nl/wiki/index.php/IDEAS:StrategicFeedback or contact Johan Jeuring (johanj(a)cs.uu.nl, +31 6 40010053).

Haddock and type operators
by Wolfgang Jeltsch 19 Apr '07

19 Apr '07

Hello everybody, I urgently need Haddock support for type operators like in the following code snippet: infix 2 :::, := infixl 9 :.: data name ::: value = name := value newtype Composition f g a = Composition { runComposition :: f (g a) } type (:.:) = Composition Does anybody know whether this is easy to implement or whether there is a quick hack to make this work? Can I do the hacking myself or is deeper knowledge of the Haddock source code necessary to provide this feature? Thank you in advance for any help. Best wishes, Wolfgang

haskell question
by Greg Meredith 18 Apr '07

18 Apr '07

Haskellians, In the attached file i have implemented the bare bones core of the syntax -- pre structural equivalence -- of Milner's presentation of \pi via abstractions and concretions. (There's a minor twist in that the notion of location affords more structure than in Milner's original presentation which i have added to support an ultimate probabilistic interpretation.) The file compiles with ghc as is. If you uncomment the last section, however, you see that to close the loop on the constraints for the agent syntax we hit a typing error. i think this is a hard constraint in Haskell that prevents this level of generality in the specification, but maybe you can see a way around it. i'm certainly no Haskell expert. Best wishes, --greg P.S. The reason for this level of generality is that with it you can close the loop and form a mutual recursion between the types for the syntax of processes and the type of names -- without having that choice predesigned into the structure of processes (or names). i can do this trick in OCaml with recursive modules, but it's definitely not pretty. i was hoping Haskell could make it pretty. -- L.G.

Haskell job
by Lennart Augustsson 18 Apr '07

18 Apr '07

Hi all, Credit Suisse has started using Haskell within GMAG, the group that provides financial analytics for the bank. The main use of Haskell is for a Domain Specific Embedded Language that is being used by the people writing the financial analytics (these people typically have a PhD in mathematics or physics). We are looking to extend our Haskell group (which currently is me and Ganesh Sittampalam), so if you're an experienced Haskell person take the chance!
