…is now me.
I’ve talked to the previous maintainer who is no longer interested. There was a small change required to support the new ghc (7.10), so I also released a new version. Since the new version only benefits people who need a new ghc, I also added the source-repository field in the cabal file, despite it breaking cabals older than 1.6.
According to hackage, wl-pprint was authored by Daan Leijen. The new github repo is up at https://github.com/sinelaw/wl-pprint. I’ve taken the liberty of forking based on someone else’s patch for GHC 7.10 - thank you Alex Legg!
Incidentally, on hackage, there are several packages with the substring ‘wl-pprint’ in their names, some are newer and better maintained and have more features than others. This situation is rather confusing. wl-pprint itself is being used as a dependency by at least one package I need (language-ecmascript).
It would be nice if the community converged on a single Wadler-pretty-printer package. (Probably not wl-pprint - maybe ansi-wl-pprint?)
