[Haskell-cafe] GHC API output files options problem
Hi all, we are working on a Haskell support plugin for IntelliJ IDEA, and need to provide correct compilation of Haskell programs. We compile the latter using GHC API, with options specifying .hi and .o paths. For some reason, unlike a standalone GHC compilation, GHC API ignores the values of the outputFile and outputHi flags. Please find attached a minimal example where "err_test.hs" uses GHC API to compile "src/A.hs". Thus, "test_ghc.sh" and "test_my.sh" should do the same, but the first works correctly while the latter puts "use.o" and "use.hi" to the "src" folder. To launch "test_my.sh", please change the value of lib in "err_test.hs" according to your GHC installation path. Thank you very much in advance!

[Haskell-cafe] ANNOUNCE: docidx-1.0.0
Hi all. I'd like to announce docidx, a new tool for Haskell documentation: http://hackage.haskell.org/package/docidx http://github.com/gimbo/docidx.hs docidx is a program which creates a static HTML page indexing your installed packages, with links to your local haddock docs and to each package's hackage page. It covers global and user packages, and handles multiple installed versions sensibly. Here's how the output looks: http://github.com/gimbo/docidx.hs/raw/master/examples/example.png The idea is to complement the "index by module name" which Cabal creates and maintains. Sometimes you want to find things by package. :-) (But note that unlike Cabal's index, docidx's isn't automatically updated when you install a new package; so, I run it once an hour from cron.) Please see the github page for more details, including customisation options. Hopefully somebody will find this useful. Maybe one day it could be part of cabal-install? :-) Thanks! -Andy PS: A bit of history/due credit: Martijn van Steenbergen did something similar in PHP in early 2009: http://thread.gmane.org/gmane.comp.lang.haskell.cafe/53531/focus=53572 ; then I wrote a static version in Python later that year: http://gimbo.org.uk/blog/2009/09/23/ ; then Andy Price ported that to Haskell: https://github.com/andyprice/docidx.hs ; finally, I rewrote that to build the index via Cabal rather than walking the filesystem directly - and here we are. -- Andy Gimblett hask...@gimbo.org.uk ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

Re: [Haskell-cafe] How to determine minimal dependency of package
Based on the package versioning policy [1], A.B is a major version, so if you know that it works with 1.2, then it is reasonably safe to specify the range >= 1.2 && <1.3, as no major api breaking changes should occur within the 1.2 range (ie, 1.2.1 to 1.2.2, etc) 1. http://www.haskell.org/haskellwiki/Package_versioning_policy#Version_numbers On Jul 15, 2011, at 10:56 AM, Anthony Cowley wrote: > On Fri, Jul 15, 2011 at 10:48 AM, yi huang wrote: >> I'm writing my first haskell package, how do i determine the minimal >> dependency of it, for example, it use Data.Data, how do i know which version >> of base package first introduce Data.Data module, i can't find the answer >> with google. > > You should specify the minimum version you have tested with. > > Anthony > > ___ > Haskell-Cafe mailing list > Haskell-Cafe@haskell.org > http://www.haskell.org/mailman/listinfo/haskell-cafe ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

I've been using docidx for a while now. It's a great little tool. I highly recommend to anyone looking for a centralized documentation tool.

Recall that signals in Animas/Yampa are conceptually continuous, which means that an ArrowChoice instance would need to make a choice at every instant. This would expose the underlying sample rate.
