ANN: TagSoup library 0.6
by Neil Mitchell 23 Apr '08

23 Apr '08

Hi I am pleased to announce the TagSoup 0.6 library, available from Hackage: * http://hackage.haskell.org/cgi-bin/hackage-scripts/package/tagsoup "TagSoup is a library for extracting information out of unstructured HTML code, sometimes known as tag-soup. The HTML does not have to be well formed, or render properly within any particular framework. This library is for situations where the author of the HTML is not cooperating with the person trying to extract the information, but is also not trying to hide the information." You may also be interested in: * TagSoup home page: http://www-users.cs.york.ac.uk/~ndm/tagsoup/ * TagSoup manual: http://www.cs.york.ac.uk/fp/darcs/tagsoup/tagsoup.htm New Bits ------------- * The primary reason for this release is that the API has changed. If you use parseTagsOptions (instead of the more standard parseTags), you will need to pass a ParseOptions type (previously an Options type), which can be created with parseOptions (previously options). This change should be simple to make, although anyone having problems is welcome to email me. * I have updated the Google Tech News example, as Google changed the HTML they generate. * Included in this release are two experimental features: Render and Tree. I welcome potential users to email me and check they meet their needs. Render lets you render a TagSoup stream, so you can take some TagSoup, modify it, and write it out. For example: Text.HTML.TagSoup.Render> renderTags [TagOpen "b" [],TagText "Hello",TagClose "b"] "<b>Hello</b>" Tree lets you view a TagSoup stream as a tree of nested tags. For example: Text.HTML.TagSoup.Tree> tagTree [TagOpen "b" [],TagText "Hello",TagClose "b"] [TagBranch "b" [] [TagLeaf (TagText "Hello")]] Thanks Neil

The following libraries are available, providing support for a wide range of Haskell web programming scenarios: * json JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language, Standard ECMA-262 3rd Edition - December 1999. This library provides a validating parser and pretty printer for converting between Haskell values and JSON. http://hackage.haskell.org/cgi-bin/hackage-scripts/package/json * xml A simple, lightweight XML parser/generator. http://hackage.haskell.org/cgi-bin/hackage-scripts/package/xml * utf8-string A UTF8 layer for IO and Strings. The utf8-string package provides operations for encoding UTF8 strings to Word8 lists and back, and for reading and writing UTF8 without truncation. http://hackage.haskell.org/cgi-bin/hackage-scripts/package/utf8-string * selenium Haskell bindings to communicate with a Selenium Remote Control server. This package makes it possible to use Haskell to write test scripts that exercise web applications through a web browser. http://hackage.haskell.org/cgi-bin/hackage-scripts/package/selenium * curl libcurl is a client-side URL transfer library, supporting FTP, FTPS, HTTP, HTTPS, SCP, SFTP, TFTP, TELNET, DICT, LDAP, LDAPS and FILE. libcurl supports SSL certificates, HTTP POST, HTTP PUT, FTP uploading, HTTP form based upload, proxies, cookies, user+password authentication (Basic, Digest, NTLM, Negotiate, Kerberos4), file transfer resume, http proxy tunneling and more! This package provides a Haskell binding to libcurl. http://hackage.haskell.org/cgi-bin/hackage-scripts/package/curl * sqlite Haskell binding to sqlite3 <http://sqlite.org/>, a light, fast database. http://hackage.haskell.org/cgi-bin/hackage-scripts/package/sqlite * feed Interfacing with RSS (v 0.9x, 2.x, 1.0) and Atom feeds http://hackage.haskell.org/cgi-bin/hackage-scripts/package/feed * mime Haskell support for working with MIME types. http://hackage.haskell.org/cgi-bin/hackage-scripts/package/mime Together these fill in a big chunk of the web programming stack for Haskell. Get the code! You can find all the cabalised packages on hackage.haskell.org. About: Galois <http://galois.com> researches, designs and develops high assurance technologies for security-critical systems, networks and applications. We use Haskell as a primary development tool for producing robust components for a diverse range of clients. Web-based technologies are increasingly important in this area, and we believe Haskell has a key role to play in the production of reliable, secure web software. The culture of correctness Haskell encourages is ideally suited to web programming, where issues of security, authentication, privacy and protection of resources abound. In particular, Haskell's type system makes possible strong static guarantees about access to resources, critical to building reliable web applications. We hope that the release of this suite of libraries to the community will push further the adoption of Haskell in the domain of web programming.

DRAFT: Haskell' status update
by Simon Marlow 22 Apr '08

22 Apr '08

Those on the Haskell' mailing list may have seen recent signs of activity on the Haskell' front. I thought I should clarify the current status, and update the community on our plans for Haskell'. The main sticking point in the design of Haskell' has been the type system: namely whether Haskell' should have Functional Dependencies or Type Families. This issue is still undecided, although the experts are hard at work on developing a stronger understanding of Type Families in particular. Nevertheless, the committee feels that we cannot have a Haskell' without some way to resolve ambiguities when using multi-parameter type classes, be it Functional Dependencies (FDs) or Type Families (TFs). For one thing, a great deal of existing code uses FDs or depends on code that does, so unless we adopt one of these extensions all this code will still exist outside of Haskell', and that is far from ideal. So we decided to proceed in two stages: - "Haskell' alpha" will be a complete language specification, including all the modifications and additions we want to make to the language *except* for FDs or TFs. - Haskell' will follow afterward, adding either FDs or TFs. The motivation for this two-stage approach is that we can make progress on all the other parts of the language without being blocked on the type system, we can start work on implementing Haskell' alpha in our compilers, users can start using the new standard, and we can gain some experience with using it in practice. On the process side of things, we're now tracking the status of all language design proposals on this page: http://hackage.haskell.org/trac/haskell-prime/wiki/Status and as usual all the Haskell' resources are on the wiki: http://hackage.haskell.org/trac/haskell-prime/wiki The committee have been discussing various proposals amongst ourselves over the past few weeks, with the goal of making as many concrete decisions as possible. However, the general policy is still for technical discussions to take place in public, as far as possible. Changes to the status page are sent to the public mailing list, and we welcome comments on any of the issues, regardless of status. Thanks for your patience :-) And rest assured that progress is being made! Cheers, Simon (and the Haskell' committee)

GSoC accepted projects
by Malcolm Wallace 22 Apr '08

22 Apr '08

Haskell.org is pleased to announce that we received 7 funded student slots from Google for this year's Summer of Code. Of the 30 proposals we received, the mentoring group chose the following 7: * GHC API Improvements by Thomas Schilling, mentored by Simon Marlow * Dynamically Loaded Plugins for the Glasgow Haskell Compiler by Maximilian Conroy Bolingbroke, mentored by Sean Seefried * Haskell API Search as an interface to Hackage by Neil Mitchell, mentored by Niklas Broberg * Language.C, a standalone parser/pretty printer library for C99 by Benedikt Huber, mentored by Iavor S. Diatchki * Cabal 'make-like' dependency framework by Andrea Vezzosi, mentored by Duncan Coutts * #1560 Efficient maps using generalised tries by Jamie Brandon, mentored by Adrian Charles Hey * Data parallel physics engine by Roman Cheplyaka, mentored by Manuel M. T. Chakravarty Slightly fuller details at http://code.google.com/soc/2008/haskell/about.html Congratulations to these students! Before coding begins officially at the end of May, there is a "community bonding period", where the students and community are encouraged to interact and further refine the work that will be done. To those students that did not get funding: do not be disheartened. Almost all of the proposals were good, and we had some difficult choices to make. What's more, since this is Open Source, you can continue to work on your projects anyway! Many of them will be useful to the community. In fact, Google have said that if any GSoC applicant manages (in the judgement of the mentors) to complete their project by the end of the summer, despite not receiving a funded place, they will send you a goodie-bag of Google swag (including a standard Google T-shirt, not the special GSoC one). Regards, Malcolm

ANNOUNCE: Generic Haskell 1.80 (Emerald)
by Thomas van Noort 21 Apr '08

21 Apr '08

Generic Haskell version 1.80 (Emerald) ====================================== We are happy to announce the fifth release of Generic Haskell, an extension of Haskell that facilitates generic programming. Generic Haskell includes the following features: * type-indexed values -- generic functions that can be instantiated on all Haskell data types. * type-indexed types -- types which are indexed over the type constructors underlying Haskell datatypes. The Generic Haskell compiler takes Generic Haskell source and produces Haskell code. Changes since 1.62 (Diamond) ---------------------------- * Generic views for generic types [1] are now supported. * The implementation of type-indexed types is improved. Download -------- The Generic Haskell compiler is available in source and binary distributions. Binaries for Linux, Windows, and MacOSX are available. These are available from: http://www.generic-haskell.org/compiler.html The documentation is also available separately from that page. For more general information, point your browser to: http://www.generic-haskell.org Why Generic Haskell? -------------------- Software development often consists of designing datatypes, around which functionality is added. Some functionality is datatype specific, whereas other functionality is defined on almost all datatypes in such a way that it depends only on the structure of the datatype. A function that works on many datatypes in this way is called a generic function. Examples of generic functionality include editing, pretty-printing or storing a value in a database, and comparing two values for equality. Since datatypes often change and new datatypes are introduced, we have developed Generic Haskell, an extension of the functional programming language Haskell that supports generic definitions, to save the programmer from (re)writing instances of generic functions. The original design of Generic Haskell is based on work by Ralf Hinze. Pleasant programming, The Generic Haskell Team at Utrecht University info(a)generic-haskell.org [1] Thomas van Noort. Generic views for generic types. Master's thesis, Utrecht University, 2008.

Workshop July 4, 2008 SCOPE The increased complexity of Web sites and the explosive growth of Web-based applications has turned their design and construction into a challenging problem. Nowadays, many companies have diverted their Web sites into interactive, completely-automated, Web-based applications (such as Amazon, on-line banking, or travel agencies) with a high complexity that requires appropriate specification and verification techniques and tools. Systematic, formal approaches to the analysis and verification can address the problems of this particular domain with automated and reliable tools that also incorporate semantic aspects. We solicit original papers on formal methods and techniques applied to Web sites, Web services or Web-based applications, such as: * rule-based approaches to Web site analysis, certification, specification, verification, and optimization * formal models for describing and reasoning about Web sites * model-checking, synthesis and debugging of Web sites * abstract interpretation and program transformation applied to the semantic Web * intelligent tutoring and advisory systems for Web specifications authoring * Web quality and Web metrics * Web usability and accessibility * Testing and evaluation of Web systems and applications The WWV series provides a forum for researchers from the communities of Rule-based programming, Automated Software Engineering, and Web-oriented research to facilitate the cross-fertilization and the advancement of hybrid methods that combine the three areas. The previous WWV editions were: WWV'07 (Venice, Italy), WWV'06 (Paphos, Cyprus), and WWV'05 (Valencia, Spain). LOCATION WWV'08 will be held in July in the convention centre of the University of Siena, Italy: http://www.unisi.it/santachiara/ The workshop will be co-located with WFLP'08: http://wflp08.dimi.uniud.it/ WORKSHOP VENUE Siena is one of the nicest city in Italy.

PLID'08 - 2nd Call for Contributions
by Samir Genaim 18 Apr '08

18 Apr '08

********************************************************* * The Fourth International Workshop * * on * * Programming Language Interference and Dependence * * * * co-located with LOPSTR'08, PPDP'08 and SAS'08 * * * * 15 July, 2008, Valencia, Spain * * * * Venue: The Technical University of Valencia * * * * 2nd Call for Contributions * * * * http://www.clip.dia.fi.upm.es/Conferences/PLID08 * * * ********************************************************* Important Dates =============== Expression of interest June 1, 2008 Extended abstract June 15, 2008 Workshop July 15, 2008 Workshop Description ==================== Interference and dependence are closely related concepts, the first being the observable phenomenon connected to the second. Interference essentially means that behaviour of some parts of a dynamic system may influence the behaviour of other parts of the system. Dependence specifies the relation between the semantics of sub-components of a dynamic system. Discovering, measuring and controlling interference is essential in many aspects of modern computer science, in particular in security, program analysis and verification, debugging, systems specification, model checking, program manipulation, program slicing, reverse engineering, data mining, distributed databases and systems biology. Doing these things requires theories, models and semantics for interference and dependence, as well as algorithms and tools for analysis and reasoning about interference and dependence. The aim of this workshop is to gather together the community of people that study dependence and interference from the different points of view in order to generate new possible research directions. PLID is devoted to bridging all these communities and assisting work towards a common goal, providing the appropriate environment for reasoning about the state of the art in interference and dependence. Topics of interest include but are not limited to: * Security against unwanted interference and dependence * Models and theories of program interference * Algorithms for reducing or removing interference or for ameliorating its effects * Theory and foundations of program slicing and related dependence analyses * Resource declassification theories * Semantics of dependence and interference * Analyses based on interference and dependence * Abstract interpretation for dependence and interference * Dependence and interference in specifications * Slicing models and specifications * Interaction between dependence and refinement Keynote Speaker =============== Gilles Barthe, IMDEA-software (Madrid, Spain) Submission ========== The workshop welcomes contributions of on-going work and ideas in the field of dependence and interference. Those who are interested in having a talk at the workshop and/or discussing issues related with these subjects are invited to send your expression of interest to Samir Genaim (samir at clip.dia.fi.upm.es) before June 1st, 2008. There will be no formal publication of papers. A web-page will be organised collecting all the workshop contributions. Submitted extended abstracts should be of at most 10 pages LNCS-style and should be sent before June 15th 2008.
