Hi
I see that I can read a .hs file and output a .ycr by calling in a shell yhc File.hs –core
You might also want to pass -linkcore instead, depending on your use - some people choose -core, some -linkcore.
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 ?
It is, and its in the index, but isn't being searched for. Whats particularly worrying is that I wrote the code that does the searching, so its most likely my fault... See http://www.cs.york.ac.uk/fp/yhc/snapshot/docs/Yhc-Core-Serialise.html#v%3AloadCore
Second, is there a way of substituting the call to system by some Haskell code?
No, not currently. I have found the system call to be perfectly sufficient.
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 Where C:\tools\yhc is where I unpack the .zip file downloaded.
If you are developing Yhc programs you will also need to check out the darcs repository (but not compile it). Then when doing linking you'll need to include something like: ghc --make Main.hs -id:\sources\yhc\current\src\libraries\core -id:\sources\yhc\current\depends\play Where d:\sources\yhc\current is the Yhc darcs directory. We'll be releasing a .cabal package shortly which means this step will no longer be necessary, but shouldn't be too hard for now. Any hints on what you are hoping to do with Yhc.Core? We might be able to provide further information, and will certainly be interested to see the results :) Thanks Neil _______________________________________________ Yhc mailing list [email protected] http://www.haskell.org/mailman/listinfo/yhc
