Re: [Haskell-cafe] TH splicing and recompilation checking

Re: [Haskell-cafe] TH splicing and recompilation checking
There is a GHC ticket about implementing a DEPENDS pragma for doing this [0]. There are patches attached, but it looks like it isn't finished yet.

Re: [Haskell-cafe] TH splicing and recompilation checking
Yup, such a thing exists! I think it's a little bit obscure because for some bizarre reason it isn't reexported by Language.Haskell.TH: http://hackage.haskell.org/packages/archive/template-haskell/2.8.0.0/doc/html/Language-Haskell-TH-Syntax.html#v:addDependentFile -Michael On Tue, Jul 16, 2013 at 10:41 AM, Johannes Waldmann < waldm...@imn.htwk-leipzig.de> wrote: > Hi. > > we are using template Haskell to splice in some code > that is produced by reading and transforming the contents of another file. > > now, if this "other file" is touched (by editing), > but not the main file, then ghc (and cabal) do not realize > that the main file does need to be recompiled. > > is there a way to tell them about the dependency? > > (example main file: > https://github.com/apunktbau/co4/blob/master/CO4/Test/Queens.hs) > > - J.W. > > > > ___ > Haskell-Cafe mailing list > Haskell-Cafe@haskell.org > http://www.haskell.org/mailman/listinfo/haskell-cafe > ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
