caching ~/.cabal with github actions on windows
I can't get this to work. It works perfectly fine on Linux and MacOS but on Windows cabal always re-builds all the dependencies. The cache post-action on Windows tells me that the cache hasn't changed, which means cabal actually re-created the ~/.cabal directory exactly as it was in the cache! Is this a known bug in cabal on Windows? Does anyone have a work-around? Cheers Ben
cabal-install doesn't use ~/.cabal on Windows. See https://hackage.haskell.org/package/directory-1.3.6.1/docs/System-Directory.... - Oleg On 13.11.2020 12.43, Ben Franksen wrote:

Note that if you use the setup-haskell action (https://github.com/actions/setup-haskell), you can get the directory from its outputs, i.e. `${{ steps.setup-haskell-cabal.outputs.cabal-store }}`. Cheers, --OM On 11/13/20 12:54 PM, Oleg Grenrus wrote:

Thanks, I'll try that. Cheers Ben

It hasn't completed but looks pretty good. In fact the cabal store path gets shown as path: C:\sr I would never have guessed that path, nor did I see it in the cabal docs. (BTW, the "setup-haskell-cabal" in your reply is the id: that you have given your setup-haskell step; it took me a while to figure that out since I am pretty new to github actions). Thanks again Ben
Caching works now and re-running the job gets it down to 2 minutes (from 15 for the first run). Awful! Thanks! Cheers Ben Am 13.11.20 um 13:12 schrieb Ben Franksen:

Thanks. I already suspected that was causing the problem, so I tried to set CABAL_DIR to a fixed location (and cache that instead): env: CABAL_DIR: ${{ github.workspace }}/dot-cabal Again, this works fine on Linux and MacOS but not on Windows. Cheers Ben
