It fails with "fatal: not a tree object"
<exarkun>
And it seems to be trying to checkout a git repository that doesn't exist
<michaelpj>
what is "it"?
<exarkun>
`nix build -f default.nix`
<michaelpj>
can you be more specific about what you're doing and what fails?
<exarkun>
I followed the "setting-up-the-binary-cache" instructions and then I copied the default.nix from "scaffolding" into my project root and ran `nix build -f .`
<exarkun>
Scratch what I said about checking out a repo that doesn't exist, seems that it does exist, and it's one of the dependencies of the project I copied the scaffolding in to.
<exarkun>
And I see now that for dependencies fetched from git the sha256 is required but isn't currently in my stack.yaml
<michaelpj>
you can also pass them in via the `sha256map` argument to `project` if you don't want to modify your `stack.yaml` with nix stuff
<michaelpj>
not sure if that's in the docs yet
<exarkun>
yea I see that
<exarkun>
trying with a modified stack.yaml for now

anyone with a working HLS 0.7.0 via haskell.nix? :)

ptival[m]: can that be done?
<shapr>
I would like to do that
<ptival[m]>
I tried to naively update my 0.6.0 configuration, but I got cabal errors about shake-bench for ghcide 0.6.0.1 and I don't feel qualified enough to figure out what it's complaining about :(
<shapr>
I've seen instructions for stock nix for hls, but not for haskell.nix
<michaelpj>
I've got a 0.6.0, but I haven't tried to update to 0.7.0
<michaelpj>
just bumped mine to 0.7.1
<michaelpj>
worked fine
<michaelpj>
although I still have `configureArgs = "--disable-benchmarks"`, because that used to be broken. Might help with the shake-bench issue
<michaelpj>
yeah, it still doesn't work without that, don't know why
<ptival[m]>
ah thanks, that's probably all I needed!
