write cabal.config / loosen bounds about cabal-bounds HOT 6 CLOSED

What you're able to do is to set the versions to the ones of a haskell platform, try to
build it, rebuild with --allow-newer, and finally set the upper bounds to the ones of the build:
cabal-bounds update --haskell-platform=2013.2.0.0 project.cabal
cabal install
cabal install --allow-newer
cabal-bounds update --upper project.cabal dist/dist-sandbox-*/setup-config

I want to keep the scope of cabal-bounds on the cabal file and even in your
workflow you want to modify the cabal file at the end, so using a cabal.config
doesn't seem to give you that much.

I think a more common workflow is to start a project and initialize your bounds to the
ones of a haskell platform and then try to loosen the upper bounds.

but i could do any updates to the .cabal by hand, avoiding the reformatting. on the other hand, i ideally would want a tool to download cabal.configs for different platform or stackage versions, and this might certainly go beyond the intended scope of cabal-bounds.

If you want to give a try on such a tool, have a look at the functions
libraries, haskellPlatformLibraries and installedLibraries inside of
lib/CabalBounds/Main.hs. I think it's quite straight forward to generate
a cabal.config from the result of these functions.

i already noticed you have nice hard-coded versions for the platform releases. where did you obtain those? just by looking at the contents of the tarballs?

from cabal-bounds.

There has been a web side comparing the versions of the libraries for each haskell platform. But
I can't recall where it was.

i found https://github.com/haskell/haskell-platform/wiki/Library-VersionMatrix, but that seems outdated. i'll search some more / ask around.

Thansk for your replies.
