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 14 Dec '13

14 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

GLUT, FLGW, FLGW-b
by Vlad Lopatin 13 Dec '13

13 Dec '13

Hey guys, I keep reading (wiki) that GLUT is a legacy package and some libraries (e.g. GLFW) are meant to replace it. I also see that some of the GLUT functionality is based on fixed pipeline. What is the current status of Haskell GLUT? Is it 'to stay' or something that is going to be deprecated at some point? Should one try replacing it with GLFW(-b) in a project, if fixed pipeline is not expected to be used? Regards, Vladimir.
