ANN: hledger 0.4 released
by Simon Michael 03 Apr '09

03 Apr '09

Dear all, I have released hledger 0.4 on hackage. There is also a new website at http://hledger.org , with screenshots (textual!), a demo (will it survive!?), and docs (not too many!) Release notes are at http://hledger.org/NEWS , and bravely pasted below. In case you forgot: hledger is a text-mode double-entry accounting tool. It reads a plain text journal file describing your transactions and generates precise activity and balance reports. I use it every day to track money and time, and as the basis for client invoices and tax returns. hledger is a partial clone, in haskell, of John Wiegley's excellent ledger. I wrote it because I did not want to hack on c++ and because haskell seemed a good fit. Please cabal update and cabal install hledger and give it a whirl. Install with the "-f happs" flag to enable the new happstack-based web interface. I am sm on the #ledger channel on freenode, and I welcome your feedback, especially if you notice a problem. Best - Simon ------------------------------------------------- 2009/04/03 hledger 0.4 released Changes: * new "web" command serves reports in a web browser (install with -f happs to build this) * make the vty-based curses ui a cabal build option, which will be ignored on MS windows * drop the --options-anywhere flag, that is now the default * patterns now use not: and desc: prefixes instead of ^ and ^^ * patterns are now case-insensitive, like ledger * !include directives are now relative to the including file (Tim Docker) * "Y2009" default year directives are now supported, allowing m/d dates in ledger * individual transactions now have a cleared status * unbalanced entries now cause a proper warning * balance report now passes all ledger compatibility tests * balance report now shows subtotals by default, like ledger 3 * balance report shows the final zero total when -E is used * balance report hides the final total when --no-total is used * --depth affects print and register reports (aggregating with a reporting interval, filtering otherwise) * register report sorts transactions by date * register report shows zero-amount transactions when -E is used * provide more convenient timelog querying when invoked as "hours" * multi-day timelog sessions are split at midnight * unterminated timelog sessions are now counted. Accurate time reports at last! * the test command gives better --verbose output * --version gives more detailed version numbers including patchlevel for dev builds * new make targets include: ghci, haddocktest, doctest, unittest, view-api-docs * a doctest-style framework for functional/shell tests has been added * performance has decreased slightly: || hledger-0.3 | hledger-0.4 | ledger-0.3 ==============================++========== -f sample.ledger balance || 0.02 | 0.01 | 0.07 -f sample1000.ledger balance || 1.02 | 1.39 | 0.53 -f sample10000.ledger balance || 12.72 | 14.97 | 4.63 Contributors: * Simon Michael * Tim Docker * HAppS, happstack and testpack developers Stats: * Known errors: 0 * Commits: 132 * Committers: 2 * Tests: 56 * Non-test code lines: 2600 * Days since release: 75

03 Apr '09

GTTSE 2009, 06-11 July, 2009, Braga, Portugal 3rd International Summer School on Generative and Transformational Techniques in Software Engineering http://gttse.wikidot.com/ *** Registration is now open *** *** Early Registration Deadline: April 24, 2009 *** SCOPE AND FORMAT The summer school brings together PhD students, lecturers, technology presenters, as well as other researchers and practitioners who are interested in the generation and the transformation of programs, data, models, meta-models, and documentation. This concerns many areas of software engineering: software reverse and re-engineering, model-driven approaches, automated software engineering, generic language technology, to name a few. These areas differ with regard to the specific sorts of meta-models (or grammars, schemas, formats etc.) that underlie the involved artifacts, and with regard to the specific techniques that are employed for the generation and the transformation of the artifacts. The tutorials are given by renowned representatives of complementary approaches and problem domains. Each tutorial combines foundations, methods, examples, and tool support. The program of the summer school also features invited technology presentations, which present setups for generative and transformational techniques. These presentations complement each other in terms of the chosen application domains, case studies, and the underlying concepts. The program of the school also features a participants workshop. All summer school material will be collected in proceedings that are handed out to the participants. Formal proceedings will be compiled after the summer school, where all contributions are subjected to additional reviewing. The formal proceedings of the previous two instances of the summer school (2005 and 2007) were published as volumes 4143 and 5235 in the Lecture Notes in Computer Science series of Springer-Verlag. TUTORIALS * Software Product Line Refactoring Paulo Borba, Universidade Federal de Pernambuco, Recife, Brazil * The TXL Source Transformation Cookbook James R.

Parsing Haskell?
by Daniel Lincke 01 Apr '09

01 Apr '09

Hi Haskellers, I am looking for a parser which can parse Haskell code and build an syntax tree out of it. The syntax tree should be storable in some reasonable file format in order to use it as an input for applications like programm transformation systems. Is there something like this available? The Haskell compiler ghc and the interpreter hugs also have to do parsing, is there a possibility to 'abuse' them as parsers? Greets and thanks, Daniel -- Dipl.-Inf.

DEFUN09: Call for Talks & Tutorials (co-located w/ ICFP09)
by Matthew Fluet (ICFP Publicity Chair) 01 Apr '09

01 Apr '09

Call for Talks and Tutorials ACM SIGPLAN 2009 Developer Tracks on Functional Programming http://www.defun2009.info/ Edinburgh, Scotland, September 3 and 5, 2009 The workshop will be held in conjunction with ICFP 2009 http://www.cs.nott.ac.uk/~gmh/icfp09.html Important dates Proposal Deadline: June 5, 2009, 0:00 UTC Notification: June 19, 2009 DEFUN 2009 invites functional programmers and researchers who know how to solve problems with functional progamming to give talks and lead tutorials at the The ICFP Developer Tracks. We want to know about your favorite programming techniques, powerful libraries, and engineering approaches you've used that the world should know about and apply to other projects. We want to know how to be productive using functional programming, write better code, and avoid common pitfalls. We invite proposals for presentations in the following categories. Lightning talks 5- to 10-minute talks that introduce exciting and promising research or techniques that may be in progress or not yet ready for widespread use, but that offer a glimpse into the near future of real world functional programming. Examples: * Clustered high performance computing in a functional language * Making advanced type systems more accessible to working programmers * How and why we're infiltrating category theory info industry How-to talks 45-minute "how-to" talks that provide specific information on how to solve specific problems using functional programming. These talks focus on concrete examples, but provide useful information for developers working on different projects or in different contexts. Examples: * "How I use Haskell for oilfield simulations." * "How I replaced /sbin/init by a Scheme program." * "How I hooked up my home appliances to an Erlang control system." * "How I got an SML program to drive my BMW." General language tutorials Half-day general language tutorials for specific functional languages, given by recognized experts for the respective languages. Technology tutorials Half-day tutorials on techniques, technologies, or solving specific problems in functional programming. Examples: * How to make the best use of specific FP programming techniques * How to inject FP into a development team used to more conventional technologies * How to connect FP to existing libraries / frameworks / platforms * How to deliver high-performance systems with FP * How to deliver high-reliability systems with FP Remember that your audience will include computing professionals who are not academics and who may not already be experts on functional programming. Presenters of tutorials will receive free registration to CUFP 2009. Submission guidelines Submit a proposal of 150 words or less for either a 45-minute talk with a short Q&A session at the end, or a 300-word-or-less proposal for a 3-hour tutorial, where you present your material, but also give participants a chance to practice it on their own laptops. Some advice: * Give it a simple and straightforward title or name; avoid fancy titles or puns that would make it harder for attendees to figure out what you'll be talking about. * Clearly identify the level of the talk: What knowledge should people have when they come to the presentation or tutorial? * Explain why people will want to attend: o Is the language or library useful for a wide range of attendees? o Is the pitfall you're identifying common enough that a wide range of attendees is likely to encounter it? * Explain what benefits attendees are expected to take home to their own projects. * For a tutorial, explain how you want to structure the time, and what you expect to have attendees to do on their laptops. List what software you'll expect attendees to have installed prior to coming. Submit your proposal in plain text electronically to defun-2009-submissions(a)serpentine.com by the beginning of Friday, June 5 2009, Universal Coordinated Time. Organizers * Yaron Minsky (Jane Street Capital) * Ulf Wiger (Erlang Training and Consulting) * Mike Sperber - co-chair (DeinProgramm) * Bryan O'Sullivan - co-chair (Linden Lab)

Call for Contributions - Haskell Communities and Activities Report, May 2009 edition
by Janis Voigtlaender 01 Apr '09

01 Apr '09

Dear Haskellers, so much has happened in the Haskell world in the past months. Therefore, I would very much like to collect contributions for the 16th edition of the ================================================================ Haskell Communities & Activities Report http://www.haskell.org/communities/ Submission deadline: 1 May 2009 (please send your contributions to hcar at haskell.org, in plain text or LaTeX format) ================================================================ This is the short story: * If you are working on any project that is in some way related to Haskell, please write a short entry and submit it. Even if the project is very small or unfinished or you think it is not important enough -- please reconsider and submit an entry anyway! * If you are interested in any project related to Haskell that has not previously been mentioned in the HC&A Report, please tell me, so that I can contact the project leaders and ask them to submit an entry. * Feel free to pass on this call for contributions to others that might be interested. More detailed information: The Haskell Communities & Activities Report is a bi-annual overview of the state of Haskell as well as Haskell-related projects over the last, and possibly the upcoming six months. If you have only recently been exposed to Haskell, it might be a good idea to browse the November 2008 edition -- you will find interesting topics described as well as several starting points and links that may provide answers to many questions. Contributions will be collected until the submission deadline. They will then be compiled into a coherent report that is published online as soon as it is ready. As always, this is a great opportunity to update your webpages, make new releases, announce or even start new projects, or to talk about developments you want every Haskeller to know about! Looking forward to your contributions, Janis (current editor) FAQ: Q: What format should I write in? A: The required format is a LaTeX source file, adhering to the template that is available at: http://haskell.org/communities/05-2009/template.tex There is also a LaTeX style file at http://haskell.org/communities/05-2009/hcar.sty that you can use to preview your entry. If you do not know LaTeX, then use plain text. If you modify an old entry that you have written for an earlier edition of the report, you should receive your old entry as a template soon (provided I have your valid email address). Please modify that template, rather than using your own version of the old entry as a template. Q: Can I include images? A: Yes, you are even encouraged to do so. Please use .jpg format, then. Q: How much should I write? A: Authors are asked to limit entries to about one column of text. This corresponds to approximately one page, or 40 lines of text, with the above style and template. A general introduction is helpful. Apart from that, you should focus on recent or upcoming developments. Pointers to online content can be given for more comprehensive or ``historic'' overviews of a project. Images do not count towards the length limit, so you may want to use this opportunity to pep entries up. There is no minimum length of an entry! The report aims at being as complete as possible, so please consider writing an entry, even if it is only a few lines long. Q: Which topics are relevant? A: All topics which are related to Haskell in some way are relevant. We usually had reports from users of Haskell (private, academic, or commercial), from authors or contributors to projects related to Haskell, from people working on the Haskell language, libraries, on language extensions or variants. We also like reports over distributions of Haskell software, Haskell infrastructure, books and tutorials on Haskell. Reports on past and upcoming events related to Haskell are also relevant. Finally, there might be new topics we do not even think about. As a rule of thumb: if in doubt, then it probably is relevant and has a place in the HCAR. You can also ask the editor. Q: Is unfinished work relevant? Are ideas for projects relevant? A: Yes! You can use the HCAR to talk about projects you are currently working on. You can use it to look for other developers that might help you. You can use it to write ``wishlist'' items for libraries and language features you would like to see implemented. Q: If I do not update my entry, but want to keep it in the report, what should I do? A: Tell the editor that there are no changes. The old entry will be reused in this case, but it might be dropped if it is older than a year, to give more room and more attention to projects that change a lot. Do not resend complete entries if you have not changed them. -- Dr. Janis Voigtlaender http://wwwtcs.inf.tu-dresden.de/~voigt/ mailto:voigt@tcs.inf.tu-dresden.de

Haskell Platform: status update and call for volunteers
by Duncan Coutts 31 Mar '09

31 Mar '09

All, We'd like to give you an update on the status of the Haskell Platform. Background ---------- For background on what the Haskell Platform is about see these slides: http://blog.well-typed.com/wp-content/uploads/2008/11/haskell-platform.pdf The wiki page also gives an overview and links to further resources: http://www.haskell.org/haskellwiki/Haskell_Platform Current status -------------- There are no more policy questions to resolve for the first release. It is a matter of getting things done. The first platform release will contain: * ghc-6.10.2 * the "extra libs" (exact list on the issue tracker wiki below) * haddock, happy and alex * the cabal command line tool and it's dependencies. The plan calls for binary installers for Windows and OSX, a generic source tarball for Unix, and native packages for distros. Currently however things are stalled because Don and I have been too busy to put serious time into the task of building installers. It is not fair for our time problems to hold everything up. Call for volunteers ------------------- We are calling for volunteers for an action group. We need volunteers to take charge of various platforms and to manage the overall release. We would like to release a beta at the upcoming Haskell Hackathon in Utrecht (April 17-19). However this will *only* happen if people volunteer to help build distributions for different platforms. In particular we need: * Release manager / coordinator * Website with downloads and release notes * Someone in charge of each platform: * Windows installer * OSX installer * Generic Unix source tarball * Distribution packages: debian, fedora, gentoo, arch, BSD* etc Don and I will be able to help coordinate things and point people in the direction of tasks that need doing. The person in charge of each platform is responsible for building appropriate native packages / installer and coordinating the effort to test that the stuff installs ok and works. If no one volunteers, we simply won't have an Haskell Platform release for that platform. Resources: * Meta-package: darcs get http://code.haskell.org/haskell-platform * Issue tracker: http://trac.haskell.org/haskell-platform/ * Mailing list: http://projects.haskell.org/cgi-bin/mailman/listinfo/haskell-platform Please join the mailing list and volunteer! In the medium term we want to organise things with two overlapping groups. A "doers" group and a "talkers" group. The "doers" group deals with actually building installers and packages and making releases. The "talkers" group is for making decisions (in consultation with the community in general) about which packages go into the platform and what standards to demand of them. We are looking for volunteers for the action group now. As we mentioned, for the first release there is nothing for the talkers to do, though there will be plenty to do for the second major release. Duncan and Don
