2020-08-20 Revise previous opinions about absolute paths GT <bracket-notation>William Carroll1-1/+1
Unforeseen problem: `buildkite-agent` runs its builds in a separate directory, so if I want the `nix-build` command to build the newly checked out code, I need to set <briefcase> to the CWD.
2020-08-20 Restore shell.nixWilliam Carroll1-0/+10
I believe `use_nix` looks for shell.nix and then default.nix files, so I was wrong earlier when I said that I could get rid of shell.nix files altogether. I need to learn more about `use_nix` and getting environments from default.nix files.
2020-08-20 Prefer direnv's use_nix to shell.nixWilliam Carroll1-10/+0
I find it bothersome to share the list of Haskell dependencies between my default.nix and shell.nix files. A few days ago, I created a THIRD file, shared.nix, that defined the shared code b/w default.nix and shell.nix. This DRY'd things up, but it also added a new file, which I didn't like. Today I learned that direnv integrates with Nix using a function called `use_nix`. Voila! I typically already have .envrc files per-project, so this doesn't add any unnecessary files, and it allows me to delete my shell.nix files. I would use `lorri`, except that I encountered issues using Lorri on my work computer, which I'm not interested in attempting to resolve now.
2020-08-20 Move shift-time into top-level //zooWilliam Carroll1-0/+10
I'm still unsure whether or not this is a good idea, but experimenting is a good way to find out!
