Hi Ricky, Ah, I see what the error is. In general I use Yhc to compile programs for Yhc Core, but use GHC/Hugs for developing of Yhc.Core tools. Yhc obviously isn't capable of compiling Yhc.Core at the moment - it should be but it appears that DrIFT for GhcBinary isn't compatible with Yhc. Should be easy to fix, but since we were going to move to Data.Binary I'm not sure there is much point. Thanks Neil

"Error: ...\Yhc\Core\Binary.hs(8:14-8:15) Found {end-of-group} but expected one of <string> <char> <rational> <integer> ( [ <varid> <conid> _case_ _if_ _do_ _let_ \ ` <varop> <conop> ~ _"

I'm not sure how to add those paths to the include path, so I've just moved the folders from \libraries\general and src\libraries\core to \packages\yhc-base\1.0 which means yhc finds the libraries.

Again any help would be much appreciated,

Ricky

Hi

...

Firstly so I can work with it I need to use the `Core' data type which seems to be in `Yhc.Core', I realised this isn't part of the windows snapshot of YHC so I found the files within http://darcs.haskell.org/yhc

I've downloaded these files and put them into YHC's library folders.

If you are developing with Yhc.Core I would recommend at least downloading the darcs and building the libraries and the compiler (only requires Python, Scons and GHC). It shouldn't be too hard, and its usually easier to keep up to date. A simple "scons build yhc", "scons build libraries" and that should work well.

That said, once we've fixed up the library with a .cabal file, we'll start making separate snapshots of that too.

...

The problem is I'm not able to import these files into any of my own code as I get an error message.

I just add src\libraries\general and src\libraries\core to the include path and everything just works. What is your error message?

...

I understand YHC is still being developed, is there a stable version I could use for these files?

I recommend the development version, its not stable, but it does have enough users that if I make any big changes someone will hit me :) It is pretty stable - I have 4 applications which depend on it. If you have any additional needs for it, just shout, and we can always add more functionality as required.

Thanks

Neil

Hi

If you do have any questions either post them to Haskell-cafe or yhc@haskell.org and I'm sure we'll be able to get you sorted. If there is any documentation you need, and can't find, also just shout and we'll find someone to write it.

Thanks

Neil

...

Thanks for this I'll look into it.

Ricky

Hi Ricky,

...

For the last year I've been working on a program to translate between Haskell and Java. Originally this was for my third year dissertation to contribute towards my Masters in computer science at Sheffield University, UK.

I have been given the opportunity to continue this project and have become interested in using the Core representation as an intermediary language.

You might be interested in Yhc.Core - its like GHC's Core, but is simpler, untyped and (in my opinion) better supported.

http://haskell.org/haskellwiki/Yhc/API/Core

We already have a Haskell -> Javascript convertor written using

so your type of application is certainly doable using what we have already. There are quite a few users of Yhc.Core already, and everyone has had nice things to say about it :)

If you have any specific Yhc.Core questions feel free to ask away

Thanks

Neil
