Hello cafe, The haskell-src-meta package was originally written by Matt Morrow, to provide a translation from the syntax tree parsed from String by the haskell-src-exts package to Template Haskell's representation of Haskell source code, making possible a variety of interesting quasiquoters and metaprogramming. However, while the package was still fairly embryonic and incomplete, Matt disappeared from the haskell community, and his work no longer compiles with the latest versions of template haskell and GHC. Many people still had use for it, so there was some discussion about its future in a haskell-cafe thread [1] resulting in a fork [2]. After I and at least one other person duplicated the work of updating haskell-src-meta, ignorant of the fork, it was decided that maintaining forks was a less-than-ideal solution, so I volunteered to take up maintainership of a package that had by now been untouched for some ten months. Hence, haskell-src-meta-0.1.0, from a new maintainer (hello!). The functionality changes in this release are minimal, but nonzero: its primary purpose is to let the original work be used with updated TH. However, there have been some changes and additions since 0.0.6: * The previously somewhat lengthy Language.Haskell.TH.Instances.Lift is now mostly generated with template haskell using the th-lift package. * Contexts, kinds, bang patterns, unboxed word literals, newly supported in template-haskell-2.4.0.0, are used where necessary. * Use of haskell-src-exts is brought in line with newer versions. * Thanks to a patch by Jonas Duregard, a new ToDecs class has been added to handle cases where more than one Dec must be returned. I don't have any big plans for future releases: there is a lot that could do with tidying up, and some small aspects of the syntax conversion that aren't covered, but I mostly just intend to ensure it keeps building and that anyone with patches to contribute has a prompt response. How You Can Help: the easiest way is to tell me that I've put the version constraints too tightly on some dependency or other -- I have erred on the conservative side. Any other comments on the package in general are appreciated too, since this is the first time I've ever uploaded anything to Hackage. There is a github repository at http://github.com/benmachine/haskell-src-meta if you want to submit patches. Yours sincerely, Ben Millwood [1] http://www.haskell.org/pipermail/haskell-cafe/2010-July/080390.html [2] http://hackage.haskell.org/package/haskell-src-meta-mwotton
Nice work, Ben - good to see someone's going to take it on in a
slightly less half-arsed way than I was :)
cheers
