Ensure all functional scripts are (a) executable (b) have shebang This is good for shebang, and also good for future build system simplifications 2024-05-28 16:43:04 +00:00			`#!/usr/bin/env bash`

Improved logging abstraction This also gets rid of --log-type, since the nested log type isn't useful in a multi-threaded situation, and nobody cares about the "pretty" log type. 2016-04-25 13:26:07 +00:00			`path=$(nix-build dependencies.nix --no-out-link)`

Fix tests So all these years I was totally deluded about the meaning of "set -e". You might think that it causes statements like "false && true" or "! true" to fail, but it doesn't... 2014-08-21 19:50:19 +00:00			`(! nix-store -l $path)`

Then, we attempt to use that path as a `builder`, which errors because symlinks are impure or whatever. Anyways, we can fix this by using `realpath "$(mktemp)"` instead of `mktemp` directly. NB: This error doesn't seem to happen when I run the tests through `nix flake check`. I'm not sure if Nix does something to `TMP` in that case. 2023-12-18 22:04:25 +00:00			`builder="$(realpath "$(mktemp)")"`
