Hi,

I want to do some Haskell manipulation and for that I intend to use the YHC.Core.Type.

Lets say I have a function
trans :: Core -> MyAST

I see that I can read a .hs file and output a .ycr by calling in a shell
yhc File.hs –core

As said in http://yhc06.blogspot.com/2006/09/yhccore-api-available.html

And supposidly I can write a tool whose main in Haskell is

main = system “yhc File.hs -core” >> loadcore “File.ycr” >>= writeFile “File.txt” . show . trans

First, the YHC documentation at http://www.cs.york.ac.uk/fp/yhc/snapshot/docs/doc-index.html do not know about a loadcore function. Is it available ?

Second, is there a way of substituting the call to system by some Haskell code?

Third. I’m having troubles with the binary version for windows given in http://www.haskell.org/haskellwiki/Yhc/Snapshots .  For a Main.hs file containing

import Yhc.Core

main = print 42

called like

D:\tmp>yhc Main

Error: File not found, Yhc.Core

Reason: imported from Main

Looked in:

  D:\tmp\

  .

  C:\Tools\yhc\lib\yhc\packages\haskell98\1.0

  C:\Tools\yhc\lib\yhc\packages\yhc-base\1.0

Where C:\tools\yhc is where I unpack the .zip file downloaded.

I would really appreciate some help on this.

Best
