[ANN] Canberra -- Introduction to Functional Programming course (free)
by Tony Morris 15 Dec '13

15 Dec '13

*Title: *Introduction to Functional Programming *Presenters:* Mark Hibberd and Tony Morris *When: * Tuesday 4th, Wednesday 5^th & Thursday 6^th February, 9.00am -- 5.00pm (lunch will be provided) *Where: *NICTA CRL, Tower A, 7 London Circuit, Canberra ACT *Cost:* Free *Abstract:*NICTA will be hosting a hands-on, three day Introduction to Functional Programming, for interested participants (internal and external). We will be using the Haskell programming language for our journey over the three days and this session requires no prior experience with functional programming. You will be required to bring a suitable development machine (portable) for working through the exercises. You will also need to install Glasgow Haskell Compiler (http://www.haskell.org/ghc/) version 7 or higher on that machine. There are no other primary requirements. Each session will be instructed by Mark Hibberd (NICTA) and Tony Morris (NICTA), to help you along your path of FP discovery, wherever that might be. If you are interested in attending this course, please email your EOI to the below email address. In your response, it is very helpful for us to understand your goals in order to make the best of the time we will have, so please take the time to answer the below questions in your response. Your answers will not be shared- just used to construct the course structure/ material. Attendees will be selected based on the answers provided: 1. How would you rate your level of understanding of functional programming? 2. What would you hope to get out of the session? *Expression of Interest:*To haylee.alder(a)nicta.com.au <mailto:haylee.alder@nicta.com.au> by *Friday 24 January, 5pm*.

source from hayoo
by Doug McIlroy 15 Dec '13

15 Dec '13

Apologies for a false send of a part message. Here's the whole: It is a shame that when you look something up in Hayoo, you can immediately see the source, but you can't use it. To get plain source, not gussied up as HTML, you have to switch to another, multistep retrieval mechanism. It would be nice if the HTML included a link to the real source file from which it was constructed. Doug McIlroy

Using unsafePerformIO and free with CString
by Nikita Karetnikov 15 Dec '13

15 Dec '13

I’m trying to write a wrapper for a C function. Here is an example of such code: {-# LANGUAGE ForeignFunctionInterface #-} import Foreign.C.String import Foreign.C.Types import System.IO.Unsafe import Foreign.Marshal.Alloc foreign import ccall "string.h strcmp" c_strcmp :: CString -> CString -> CInt strcmp :: String -> String -> Ordering strcmp s t = unsafePerformIO $ do s' <- newCString s t' <- newCString t let n = c_strcmp s' t' -- free s' -- free t' return $ case () of _ | n == 0 -> EQ | n < 0 -> LT | otherwise -> GT Two questions: 1. May I safely use unsafePerformIO in such cases? 2. What’s the proper way of using free here? If I uncomment the above, the function returns incorrect results.

Well that's a mystery to me. Given that we've both done a cabal update, I can't think what is causing my cabal to find an install plan with default maxjump and yours not to. Maybe a someone will enlighten us. (I've belatedly dropped the haskell list from this thread.) On Sun, Dec 15, 2013, at 11:31 AM, Marko Kocić wrote: Yes, I have the same problem with cabal sandbox.

Writing a Storable instance for a C union
by Nikita Karetnikov 14 Dec '13

14 Dec '13

Could anyone explain how to write a Storable instance for MyStruct? (The key field allows to determine the type of a value inside the union.) typedef enum Key_ { ONE = 1, FOUR = 4, TWENTY = 20 } Key; struct MyStruct { Key key; union { Foo one; uint64_t four; void *twenty; }; }; Also, should I use hsc2hs to make the resulting code portable?

ANN: hledger 0.22
by Simon Michael 13 Dec '13

13 Dec '13

Hi all. I have released hledger and hledger-web 0.22. hledger is a command-line tool and haskell library for tracking financial transactions, which are stored in a human-readable plain text format. In addition to reporting, it can also help you record new transactions, or convert CSV data from your bank. Add-on packages include hledger-web (providing a web interface), hledger-irr and hledger-interest. hledger is inspired by and compatible with John Wiegley's Ledger. For more, see http://hledger.org . Install it: cabal update; cabal install hledger [hledger-web] For more installation help, see http://hledger.org/MANUAL.html#installing . Or, sponsor a ready-to-run binary for your platform: http://hledger.org/DOWNLOAD.html . Release notes (http://hledger.org/NEWS.html#hledger-0.22) **New:** - balance: with a reporting interval (monthly, yearly etc.), the [balance command](MANUAL.html#balance) will now show a multi-column report, showing either the per-period changes in balance (by default), the period ending balances starting from zero (`--cumulative`), or the actual period ending balances (`--historical`). A more detailed specification of the balance command's behaviour has been added to Hledger.Cli.Balance. - csv: rules files can now include other rules files, useful for factoring out common rules - queries: `sym:REGEXP` matches commodity symbols - register: `--average/-A` shows a running average, like ledger - in period expressions, `-` (hyphen) can be used as a more compact synonym for `from` and `to`. Eg: `-p 2012/12/1-2013/2/1` or `date:aug-`. - the add-on script examples in extra/ have been updated; get the hledger source and add .../hledger/extra/ to your PATH to make them available. They include: hledger-accountnames.hs - print account names hledger-balance-csv.hs - print a balance report as CSV hledger-equity.hs - print an entry matching all account balances hledger-print-unique.hs - print only journal entries unique descriptions hledger-register-csv.hs - print a register report as CSV **Improved:** - balancesheet: now shows just assets and liabilities, not equity - print: comment positions (same line or next line) are now preserved - queries: `amt` now uses the = operator by default, eg `amt:50` is equivalent to `amt:=50` - command line processing has been overhauled and made more consistent, and now has tests and debug output. More flags now work both before and after COMMAND: `-f`, `--rule-file`, `--alias`, `--help`, `--debug`, `--version`. Command line help, command aliases, API docs and code have been improved. - `--debug` now takes an optional numeric argument to set the debug level higher than 1, for more verbose debug output in a few cases. **Fixed:** - csv: CSV data containing non-ascii characters is now supported - build with latest versions of dependencies (text, warp, http-conduit etc.) **Release contributors:** Marko Kocić, Max Bolingbroke, and a big welcome to first-time committer John Wiegley! :) There's a rumour that a 1.0 release could be next, depending on how this one fares. All feedback welcome. Best! - Simon
