Re: Text.Printf replacement?

i'm actually not aware of many / any? package that use the printf style approach! (i could be wrong, but i suspect its not widely used?) On Thu, Sep 12, 2013 at 2:21 AM, Bart Massey wrote:

I think the only references that matter are the ones in base, no? And there aren't any there that I could find, except Text.Printf itself. If we lift Text.Printf into a printf package, then make sure that things reference this package, it should all just compile, I think.

I would vote for trying to do this for 7.8, and only merging my stuff once it's done. But I'm not willing to manage the move, since I'm not that Cabal/GHC-literate and haven't dug around in Hackage enough to know what's affected. Perhaps the biggest objection to this whole plan is the potentially large amount of packages in Hackage whose .cabal files need to change: I don't know if there's some easy way to smooth this transition?

I only see two uses of printf in ghc:

ghc/InteractiveUI.hs: let nums = map (printf "-%-3d:") [(1::Int)..] compiler/utils/Outputable.lhs: ppr (Fingerprint w1 w2) = text (printf "%016x%016x" w1 w2)

So it seems easy to replace that with some hand-written formatting.

Oh, there are also a bunch of references in libraries/. But it looks like mostly tests for bytestring and dph, so still not too bad. _______________________________________________ Libraries mailing list Libraries@haskell.org http://www.haskell.org/mailman/listinfo/libraries
