July 2003 - Hugs-Users

getContents, getLine, etc.
by Wojciech Moczydlowski, Jr 01 Aug '03

01 Aug '03

Hello everyone, I am currently writing a small program in Haskell, using Hugs under Linux to run it. The program works in a conversation mode, a user issues a lot of lengthy commands. However, backspace doesn't work, no matter which function (getContents, getLine) I use, which makes debugging and normal work with the program a nightmare. Does anyone know any workaround (i.e. sensible replacement to getLine) apart from switching to ghc and using the readline library? Wojciech Moczydlowski, Jr

From: James Kabila Madrid Spain SEND REPLY TO MY SECURED MAILBOX: ja_kabila(a)email.com Dear Sir, In appreciation of your esteemed contact received through a reliable source and the choice of your country.My name is James Kabila,from the Democratic Republic of Congo,formaly known as Zaire and the first son of the second wife of the late president Laurent Kabila. As you may be aware my father was assasinated by one of his bodyguards on the 16th day of january 2001.I escaped from being arrested by my half brother ,the current head of state. Considering the relationship between Spain and my country?s new government,my mother adviced me to leave for Spain with a trunk containing USD 17 MILLION (SEVEN-TEEN MILLION)which i deposited in a security company here in Spain.I?m here as a political refugee that's why I have to contact you so that you can come down to Spain and help me to move the money to your country for investment. This money is what me and my mother are depending on after my half brother seized all my father?s accounts and assets. I will reward you handsomely if you can assist me to move this money to your country for investment.Please keep this as a secret for the benefit of my family.I hope for your positive response soon.The bottom line is that we need to meet in Spain to arrange on the relocation of the fund to your country Interms on things I want are: 1.Help me to bank the money in a safe account. 2.Help me to get a residential papers and giving me directions as to what to invest on. Please get back to me as soon as you receive my message to enable me finalise with the security company where I deposited the fund. BEST REGARDS JAMES KABILA.

The workshop is intended to provide an open forum for researchers who wish to present and discuss new ideas and concepts, work in progress, preliminary results etc. related primarily but not exclusively to the implementation of functional or function-based languages. A not necessarily exhaustive list of topics includes language concepts type checking compilation techniques (abstract) interpretation automatic program generation (abstract) machine architectures array processing concurrent/parallel programming and program execution heap management runtime profiling and performance measurements debugging and tracing verification of functional programs tools and programming techniques Contributions on applications of functional programming, e.g., in teaching, or on theoretical work in any of the above areas are also welcome. This year's workshop is co-located with the 4th International Symposium on Trends in Functional Programming (TFP'03) <http://homepages.inf.ed.ac.uk/stg/workshops/ISTFP/>. Contributions ------------- All attendees are encouraged to submit papers to be published in the draft proceedings and to give presentations at the workshop. Submitted papers must be written in English, conform to the LNCS format (available at: http://www.springer.de/comp/authors/index.html) and not exceed 16 pages. Papers should be submitted by August 22nd as postscript or pdf files using the submission page of the workshop accessible through http://www.macs.hw.ac.uk/~ifl03 After the workshop, a high-quality subset of contributions will be published in the Springer LNCS series. All speakers attending the workshop are invited to submit a paper. Papers for the LNCS proceedings will be refereed according to normal conference standards.

These workshops bring together researchers with interests in all aspects of functional programming languages. Papers on all aspects of functional programming are welcomed, be they implementation-oriented, theoretical, or experience papers. This year's workshop is co-located with the 15th International Workshop on the Implementation of Functional Languages (IFL '03) <http://www.macs.hw.ac.uk/~ifl03>. Workshop Topics Papers on any aspect of functional programming are welcome. Papers on the following subject areas are particularly welcome. * rich type systems, including type systems for expressing resource bounds or other safety properties; * linear type systems, soft type systems, typeful programming; * reasoning about functional programs, semantics of functional languages; * inductive or co-inductive techniques, proof nets; * mobile-code functional programming languages; * parallel programming with functional languages, cost models for functional programs; * compilation of functional languages for the Java Virtual Machine; * functional aspects of imperative programming, functional bytecode; * interoperability with imperative programming languages, calling imperative from functional or vice versa; * type inference algorithms, type error repair, deep types; * strongly-typed imperative languages with inference (e.g. Cyclone); * performance measurements, optimisation techniques, implementation techniques; * experience papers: applications of functional programming or functional programming in education. The above list is not exhaustive. Papers on other topics are also welcome. Contributions All attendees are encouraged to submit papers to be published in the draft proceedings and to give presentations at the workshop. Submitted papers must be written in English and not exceed 16 pages. Papers should be written conform to the LNCS format <http://www.springer.de/comp/lncs/authors.html> and should be submitted as postscript (or pdf) by email to the workshop chair, Stephen Gilmore <stg(a)inf.ed.ac.uk>. Proceedings We intend to publish a refereed, high-quality subset of contributions in the final proceedings. The proceedings publisher is to be confirmed: previous SFP proceedings were published by Intellect. All speakers attending the workshop are invited to submit a paper. Papers for the proceedings will be refereed according to normal conference standards. This implies (among other things) that: * the paper should be written in English * the paper is well written * topic of the paper should be stated clearly * the approach to solve the problem should be outlined clearly * a detailed discussion of the solution has to be given * the solution is compared with relevant related work * there is an abstract, introduction and conclusion. * the conclusion should summarise the problem, the solution, and how this solves the problem. * the paper should not exceed 16 pages. * the paper should be written to conform to the LNCS format <http://www.springer.de/comp/lncs/authors.html>. * the paper should be submitted as postscript (or pdf) by email to the workshop chair, Stephen Gilmore <stg(a)inf.ed.ac.uk>.

defining "unzip" using foldr
by John Mann 13 Jul '03

13 Jul '03

Hello, I'm working my way through Simon Thompson's Haskell book and am having trouble with an exercise where the goal is to define "unzip" using foldr. Lambda notation and ~ , as used in the Prelude definition of unzip, have not been introduced yet. Any help on this would be appreciated.

Hi all, Can any one tell me what is the use of .hi (interface) files. I want to know the steps involved in the compilation of a .hs file. I went thru the what nhc98 roughly does and saw that it generates interface file for each module. Please enlighten as to what is the precise function of interface files.
