ANN: iteratee-parsec 0.0.2
by Maciej Piechotka 04 Mar '10

04 Mar '10

Iteratee-parsec is a library which allows to have a parsec (3) parser in IterateeG monad. It contains 2 implementations: - John Lato's on public domain. It is based on monoid and design with short parsers in mind. - Mine on MIT. It is based on single-linked mutable list. It seems to be significantly faster for larger parsers - at least in some cases - but it requires a monad with references (such as for example IO or ST). Version 0.0.2 does not differ much from 0.0.1 except that it is up-to-date with parsec 3.1.0 (version 0.0.1 is not). Regards

ANNOUNCE: Parsec 3.1.0
by Derek Elkins 04 Mar '10

04 Mar '10

Parsec is a monadic combinator library that is well-documented, simple to use, and produces good error messages. Parsec is not inherently lazy/incremental and is not well-suited to handling large quantities of simply formatted data. Parsec 3 adds to Parsec the ability to use Parsec as a monad transformer and generalizes the input Parsec accepts. Parsec 3 includes a compatibility layer for Parsec 2 and should be a drop-in replacement for code using Parsec 2. Code using the features of Parsec 3 should use the modules in Text.Parsec. Due almost entirely to the work of Antoine Latter there is a new version of Parsec 3 available. He documented some of his thoughts on this in this series of blog posts: http://panicsonic.blogspot.com/2009/12/adventures-in-parsec.html The main features of this release are: - the performance should be much better and comparable to Parsec 2 - notFollowedBy's type and behavior have been generalized Changes: - the changes to the core of Parsec lead to some changes to when things get executed when it is used as a monad transformer "In the new version bind, return and mplus no longer run in the inner monad, so if the inner monad was side-effecting for these actions the behavior of existing code will change." - notFollowedBy p now behaves like notFollowedBy (try p) which changes the behavior slightly when p consumes input, though the behavior should be more natural now. - the set of names exported from Text.Parsec.Prim has changed somewhat

ANNOUNCE: guarded-rewriting-0.1: Generic rewriting with preconditions
by José Pedro Magalhães 03 Mar '10

03 Mar '10

guarded-rewriting-0.1: Generic rewriting with preconditions ===================================================================== This is a generic rewriting library based on type classes and type families described in the paper: Thomas van Noort, Alexey Rodriguez Yakushev, Stefan Holdermans, Johan Jeuring, Bastiaan Heeren, José Pedro Magalhães. A Lightweight Approach to Datatype-Generic Rewriting. Journal of Functional Programming, Special Issue on Generic Programming, 2010. A draft version of this paper is currently available at http://dreixel.net/research/pdf/ladgr_draft.pdf. The main differences from our previous generic programming library (see http://hackage.haskell.org/package/rewriting) are the support for more datatypes (including parametrized and families of datatypes) and the possibility of adding preconditions to rewrite rules. It uses the instant-generics library, first described by Chakravarty et al. (see http://www.cse.unsw.edu.au/~chak/project/generics/) which we packaged and released separately (see http://hackage.haskell.org/package/instant-generics) Requirements ------------ * GHC 6.10.4 or later * Cabal 1.6 or later Download -------- With cabal-install: cabal install guarded-rewriting Get the package: http://hackage.haskell.org/package/guarded-rewriting Get the source: svn checkout https://subversion.cs.uu.nl/repos/project.dgp-haskell.libraries/GuardedRewr… Bugs & Support -------------- For more information visit the project homepage: http://www.cs.uu.nl/wiki/bin/view/GenericProgramming/GuardedRewriting Report issues, request features, or just discuss the library with the authors, maintainers, and other interested persons at: http://www.haskell.org/mailman/listinfo/generics

******************************************************************* Call For Papers CICLOPS-WLPE 2010 Joint Workshop on Implementation of Constraint Logic Programming Systems and Logic-based Methods in Programming Environments Edinburgh, Scotland, U.K. July 15, 2010 http://users.dsic.upv.es/~ciclops-wlpe10/ Satellite event of the 26th International Conference on Logic Programming (ICLP 2010) http://www.floc-conference.org/ICLP-home.html ******************************************************************* Important Dates: Paper Submission: March 31, 2010 Notification of Authors: April 29, 2010 Camera-ready: May 17, 2010 (tentative) Workshop: July 15, 2010 Invited talks: Programming with Boolean Satisfaction Michael Codish, Ben-Gurion University of the Negev (Israel) Solving Constraint Satisfaction Problems by a SAT Solver Naoyuki Tamura, Kobe University (Japan) Workshop description CICLOPS is a series of colloquia on the implementation of constraint logic programming. Logic and Constraint programming is an important declarative programming paradigm. The features offered by this paradigm such as rule-basedness, pattern matching, automated backtracking, recursion, tabling, and constraint solving have been proved convenient for many programming tasks. Recent improvements in implementation technologies combined with advances in hardware and systems software have made logic and constraint programming a viable choice for many real-world problems. CICLOPS'10 continues a tradition of successful workshops on Implementations of Logic Programming Systems, previously held with in Budapest (1993) and Ithaca (1994), the Compulog Net workshops on Parallelism and Implementation Technologies held in Madrid (1993 and 1994), Utrecht (1995) and Bonn (1996), the Workshop on Parallelism and Implementation Technology for (Constraint) Logic Programming Languages held in Port Jefferson (1997), Manchester (1998), Las Cruces (1999), and London (2000), and more recently the Colloquium on Implementation of Constraint and LOgic Programming Systems in Paphos (Cyprus, 2001), Copenhagen (2002), Mumbai (2003), Saint Malo (France, 2004), Sitges (Spain, 2005), Seattle (U.S.A., 2006), Porto (Portugal, 2007), Udine (Italy, 2008), and Pasadena (U.S.A, 2009). WLPE is a series of workshops on practical logic-based software development methods and tools. Software plays a crucial role in modern society. While software keeps on growing in size and complexity, it is more than ever required to be delivered on time, free of error and meeting the most stringent efficiency requirements. Thus more demands are placed on the software developer, and consequently, the need for methods and tools that support the programmer in every aspect of the software development process is widely recognized. Logic plays a fundamental role in analysis, verification and optimization in all programming languages, not only in those based directly on logic. The use of logic-based techniques in software development is a very active area in computing; emerging programming paradigms and growing complexity of the properties to be verified pose new challenges for the community, while emerging reasoning techniques can be exploited. WLPE'10 continues the series of successful international workshops on logic programming environments held in Ohio, USA (1989), Eilat, Israel (1990), Paris, France (1991), Washington D.C., USA (1992), Vancouver, Canada (1993), Santa Margherita Ligure, Italy (1994), Portland, USA (1995), Leuven, Belgium (1997), Las Cruces, USA (1999), Paphos, Cyprus (2001), Copenhagen, Denmark (2002), Mumbai, India (2003), Saint Malo, France (2004), Sitges (Barcelona), Spain (2005), Seattle, USA (2006), Porto, Portugal (2007) and Udine, Italy (2008). More information about the series of WLPE workshops can be found at http://www.cs.usask.ca/projects/envlop/WLPE/ CICLOPS-WLPE 2010 aims at bringing together, in an informal setting, people involved in research in the design and implementation of logic and constraint programming languages and systems and on logic-based methods and tools which support program development and analysis. In addition to papers describing more conceptual and theoretical work, papers describing the implementation of, and experience with, such tools will be welcome.

ANNOUNCE: jhc-0.7.3
by John Meacham 01 Mar '10

01 Mar '10

It's been a long time coming, but jhc-0.7.3 is here. If you have been following the darcs repository, there are not a whole lot of new changes, but there have been substantial fixes since 0.7.2 for those that use the tarballs or rpms. http://repetae.net/computer/jhc/ One of the most important ones is I have begun the process of standardizing on YAML for all external interfaces that may be useful to automation, this should make interfacing jhc with external tools written in any language much easier, and it will prevent me from spending time trying to invent proprietary formats every time I think of something new to spit out. right now it is used in 3 places: - dumping dependency info with --deps - library dumping with --list-libraries -v - annotating source code, for inputting to documentation generators via --annotate-source The main place it isn't used yet that I desire too is to replace the 'cabal' library description format with a true YAML file. jhc cabal files were never quite compatible with cabal ones anyway and naming them the same thing has been a source of connfusion. some of the other changes have been: features: - a lot more regression tests, many user submitted bugs are now regressions (or fixed) - support for using 'mock' to build rpms - System.Exit, System.Cmd added to base - better compatibility with ghc in some library functions - ui improvements in showing progress and errors - extended --list-libraries info - --deps dependency dumping - more francise compatible thanks to patches from droundy - more instances for bigger tuples added - uses editline if readline not available - select libraries by hash as well as version - add System.IO.Pipe - detect version of gcc needed for cross compiling to windows performance: - storage analysis - a very basic region inference enabled by default - deadcode analysis can see through partial applications now - profiled and sped up some library routines that were producing inellegant core. - figure out when top level grin functions call themselves recursively and turn them into explicit loops. bug fixes: - do expression in infix - fix strict newtype bug - U2U bug fixed - desugaring inside of list comprehensions fix - c generator doesn't mess up on unknown values - the compiler version is stored in the cache files, so multiple versions of jhc don't clobber each others cache entries - Ord instance for lists fixed - recursive type synonyms detected properly - make sure errno.h is included when errno is referenced - don't give a parse error when seeing ghc extensions to INLINE - qualified method names fix John -- John Meacham - ⑆repetae.net⑆john⑈ - http://notanumber.net/

ANN: Try Haskell! An interactive tutorial in your browser
by DekuDekuplex＠Yahoo.com 01 Mar '10

01 Mar '10

According to the top page of HaskellWiki (see http://www.haskell.org/) (under "February 2010" under "1 Headlines"), there is an alpha version of a new interactive, online Haskell interpreter entitled "Try Haskell!" at http://tryhaskell.org/. The top panel of the page features an interactive interpreter, while the bottom panel features a text tutorial. The user types in commands in the top panel according to the text tutorial, and the interpreter responds with output. There is also a "Reset" button in the upper right corner of the tool which resets the state of both panels to the default state. I just tried it out, and it appears to have been completed up to Lesson 3. So far, it apparently teaches up to lists. It was fun to try out. This tutorial somehow reminded me of an interactive Scheme tutorial, "Lists And Lists," copyrighted in 1996 by Andrew Plotkin, at http://parchment.googlecode.com/svn/trunk/parchment.html?story=http://parch…. That tutorial was arranged in the style of an adventure game, while this tutorial is more similar to a very similar Ruby tutorial, "try ruby! (in your browser)" at http://TryRuby.org/. It could be fun if somebody could come up with a Haskell version of the above-mentioned"Lists And Lists," which also includes a text-based Scheme reference on the virtual computer within the adventure game. -- Benjamin L.
