How to use settings.txt? #412

Open Minnozz opened 10 months ago

Minnozz commented 10 months ago

I'm running a local instance of Hoogle (via Nix) with my employer's packages and their dependencies. I've always noticed that hoogle.haskell.org has a more logical order for packages when there are multiple hits (ie preferring base). After some searching, I found that this is probably because of a difference in ReorderModule rules. I also see there exists a misc/settings.txt, but I don't know how to supply this file myself or why the default rules result in a different order compared to hoogle.haskell.org.

The misc/settings.txt file is read at https://github.com/ndmitchell/hoogle/blob/2f2d101ff7c4924bbaf45abbf1d290165cb8a2d7/src/Input/Settings.hs#L60 - it's a Cabal data file. So simply doing cabal install should cause it to see the settings.txt file that ships with Hoogle. Are you running Hoogle from a cabal package or from the repo?

We are using this Nix derivation to generate a Hoogle database for our own packages and their dependencies. It receives the hoogle package that is packaged in nixpkgs as input, which I believe is built using cabal.
