How do people feel about

#!/usr/bin/env runhaskell
import Distribution.Simple
main = defaultMain

instead of

#!/usr/bin/env runhaskell

> import Distribution.Simple
> main = defaultMain

#!/usr/bin/env runhaskell
import Distribution.Simple
main = defaultMain

which is simplest of all

Directory structure

Shouldn't the advise be to let all the source code be collected under src/ and the testing under test/ extra scripts under scripts/ etc.?


I was putting off (and meaning to get around to) cabalising my software until I saw how easy it was on this page. BTW, I kinda like the birdtracks as is -- kowey 09:20, 31 October 2006 (UTC)

Imported to the wikibook

I'm using this tutorial to bootstrap a the Haskell wikibook Packaging chapter. The wikibook version diverges somewhat in that it ignores the Haskell community stuff, and (one day) tries to flow with the rest of the book. -- EricKow 15:33, 10 January 2007 (UTC)

Error message about license field

Just as a heads up, I'm getting this error message after creating a project with mkcabal:

$ runhaskell Setup.lhs configure
Setup.lhs: testing.cabal:4: Parse of field 'license' failed:

Upon inspection, it seems that it doesn't like 'GPL2' or 'GPL3'. I manually changed it to 'GPL', as shown in the wiki page, and it worked. I tested this on ghc 6.6 and ghc 6.6.1. --tanimoto

Perhaps submit a patch to add support for other licenses? dons 09:25, 12 July 2007 (UTC)
