What's become of the Yhc buildbot?
by Thorkil Naur 03 Jul '08

03 Jul '08

Hello, The last build that I have recorded for my Yhc buildbot slave happened more than a month ago. Lately, I have not been able to contact the Yhc buildbot site. So, what's the status of the Yhc buildbot setup? Thanks and regards Thorkil

Experimental compilation of Haskell to Erlang
by Dimitry Golubovsky 19 May '08

19 May '08

Hi, Some time ago I became interested in compilation of Haskell programs (via Yhc Core) to Erlang to be able to run Haskell code in Erlang environment. This experiment seems to have been successful, so I'd like to publish its results for everyone to read and criticize. Results of the experiment are described in this Haskell Wiki article: http://www.haskell.org/haskellwiki/Yhc/Erlang/Proof_of_concept Any feedback is appreciated. Thanks. -- Dimitry Golubovsky Anywhere on the Web

Hi Tom, Sorry for not replying - I thought this email was sent to the whole list, but it appears you just sent it to me. > > > > Have you done --linkcore to see all the library Core files as well? > > They should be created somewhere. > > Yes, I lied again. Prelude;1() are being created elsewhere. > > I am getting a case failure in my interpreter. The pattern is > Prelude;1(), but the case expression is my System monad. Is there > anything special I need to know regarding primitive functions that > return monads? As far as I was aware, primitive functions don't return monads. I certainly don't know any underlying details regarding Monads and primitive functions. Remember that type class dictionaries will be floating everywhere, and that IO in Yhc is a newtype, so gets removed - but other than that it could be anything. Thanks Neil

single element tuple
by Tom Hawkins 14 Mar '08

14 Mar '08

Hi, Printing the core one of my programs I see: data Prelude;1() a = Preluse;1() a What is this? A single element tuple? I didn't think Haskell had these. My program has a monad similar to IO. It appears these Prelude;1() things are created in the lambda lifted version of f1. Perhaps is it the parenthesis around (System m)? data Return a = Return a World data System a = System (World -> Return a) data World = World instance Monad System where (System m) >>= k = System f1 where f1 w = f2 w' where Return r w' = m w System f2 = k r return a = System (\ w -> Return a w) It's a bit difficult to correlate arguments of lifted lambdas to the original source. Is there a convention YHC uses for adding the extra arguments to lifted lambdas? Thanks! -Tom

Hi guys, Does anyone know if the HBC format at http://www.haskell.org/haskellwiki/Yhc/RTS/hbc is up to date? Regards, Stew.

Yhc and Haskell pragmas
by Dimitry Golubovsky 09 Mar '08

09 Mar '08

Malcolm, OK, I see where it is, and even though all calls to parsePragma are commented out, the only one that would be recognized was "YHC_OPTIONS". The way I am going to use it is to grep the source for specific regexp, and then build the backend's command line accordingly. So I think that using pragma names starting with any other prefix than "YHC_" won't cause any conflict in the future, will it? Thanks, -- Dimitry Golubovsky Anywhere on the Web

Nofib .yca linked Yhc Core files
by Neil Mitchell 07 Mar '08

07 Mar '08

Hi, I have compiled .yca files for most of the nofib suite. So no one else has to do this, I've uploaded a .zip of them: http://www.cs.york.ac.uk/fp/yhc/yca.zip They may be useful to others, Thanks Neil PS. The script used to create them is: if "%1" == "build" goto build pushd %1 for /d %%i in (*) do call ..\%0 build %%i popd goto exit :build pushd %2 yhc --linkcore Main --hide copy ycr\Main.yca ..\%2.yca popd :exit

yca2swf? was coreFunc has extra argument
by Dimitry Golubovsky 04 Mar '08

04 Mar '08

Hi, Jeremy shaw wrote: and when the 'compiler' calls main it actually passes in a World value. (Or at least, in my *yca2swf* compiler I believe I do). Jeremy: could you please elaborate on this? It doesn't even google. Does this involve actionscript in any way (but I may ask mistakenly as I am not much familiar with shockwave/adobe stuff)? -- Dimitry Golubovsky Anywhere on the Web
