To quote Eelco in #5867: > Unfortunately we can't do > > evalSettings.pureEval.setDefault(false); > > because then we have to do the same in main.cc (where > pureEval is set to true), and that would allow pure-eval > to be disabled globally from nix.conf. Instead, a command should specify that it should be impure by default. Then, `evalSettings.pureEval` will be set to `false;` unless it's overridden by e.g. a CLI flag. In that case it's IMHO OK to be (theoretically) able to override `pure-eval` via `nix.conf` because it doesn't have an effect on commands where `forceImpureByDefault` returns `false` (i.e. everything where pure eval actually matters). Closes #5867 |

Nix
Nix is a powerful package manager for Linux and other Unix systems that makes package management reliable and reproducible. Please refer to the Nix manual for more details.
Installation
On Linux and macOS the easiest way to install Nix is to run the following shell command (as a user other than root):
$ curl -L https://nixos.org/nix/install | sh
Information on additional installation methods is available on the Nix download page.
Building And Developing
See our Hacking guide in our manual for instruction on how to build nix from source with nix-build or how to get a development environment.
