Some of the other regex-* libraries are interfaces to c-library backends (pcre and tre) and it is not GHC's place to come with copies of those libraries. But GHC used regex internally, so it must come with at least a single backend. > [...snip...] > > and while we are here - splitting of Base library should be very easy > task. its ghc version specific part is in GHC.* modules. these modules > should be moved into the new Core library. plus a few modules from > Data.* or System.* hierarchy they imports. plus a few modules imported > by Hugs/NHC Prelude. the rest of Base library should be pretty portable, at > least between various GHC versions. > > and independent on this work, we can always look into moving pieces of > Base into independent libs. as a rule of thumb, everything not used in > Base lib may be moved outside of it. of course, these new libs should > be included in base libs set The regex-* modules that are installed with GHC are not in the "base" package. They are in "regex-base" and "regex-posix" and "regex-compat" because I took excellent design advice and finely split the modules. I see no reason one could not by able to upgrade these on top of the GHC versions. > in particular, my hottest hope is that ghc 6.6.1 will be shipped with > fps 0.8 as separate library that will provide both backward > compatibility with 6.6 and will allow to upgrade fps without recompiling > ghc itself :D By separate library you really mean using a separate package name instead of "base". The Text.XHtml is already separate into the "xhtml" package. You are correct: as far as I can see the only module that is in "base" which might need to be split out is Data.ByteString. The same may or may not apply to Data.Sequence. Cheers, Chris _______________________________________________ Haskell mailing list Haskell@haskell.org http://www.haskell.org/mailman/listinfo/haskell
