[Fedora-packaging] Update guidelines for using darcs based sources in packages

Hi List, (Packaging list, i'm double posting because i want you guys to see this, but please put further comments on the haskell list :) ) Because the macros, last i checked were for ghc 6.10.1, some of the packages i'm still working on will only compile from darcs. I've put together a tool to help with development of packages from darcs, and i'm looking for a standardized way to note which revision from darcs is being used. Darcs has two relatively canonical ways to refer to a package, with a hash and a timestamp. Internally this tool uses both. Judging from the different ways people note svn/git/other usage in fedora packages, i've put together a few recommendations that we can use for a standard. Keep in mind, my goal is to support darcs, so please be nitpicky about these details. Just keep in mind, this is easily bikesheddable, and all i want to do is support darcs based packages systematically. Normal Haskell Tarball name: %{hackage_name}-%{version}.tar.gz Output from darcs: %{hackage_name}-%{version}.%{timestamp_from_darcs}darcs.tar.gz Accesible from: darcs dist -d %{hackage_name}-%{version}.%{timestamp_from_darcs}darcs Timestamp accessible from darcs changes --xml-output --last=1 To note this in the rpm Normal Dist: 1%{?dist} Darcs Dist 1.%{timestamp_from_darcs}darcs%{?dist} I've attached a patch to the templates that puts in a placeholder to make it clearer how to do things. Note that in the timestamp i've added . and darcs systematically. Since the macro %dist includes the . prefix, as a matter of precedent, i've noted that we should just use the prefix and suffix in the %darcs macro as well. Also, the names of everything here is not so important. What's important is that i want to take a spec file that's been generated by cabal2spec, run it through a quick sed-like script that will append the correct darcs timestamp. Darcs doesn't make the timestamps that easily available, and i'm trying to automate a few things here. Cheers, Yaakov
