2018-01-16Add pure evaluation modeEelco Dolstra
In this mode, the following restrictions apply: * The builtins currentTime, currentSystem and storePath throw an error. * $NIX_PATH and -I are ignored. * fetchGit and fetchMercurial require a revision hash. * fetchurl and fetchTarball require a sha256 attribute. * No file system access is allowed outside of the paths returned by fetch{Git,Mercurial,url,Tarball}. Thus 'nix build -f ./foo.nix' is not allowed. Thus, the evaluation result is completely reproducible from the command line arguments. E.g. nix build --pure-eval '( let nix = fetchGit { url = https://github.com/NixOS/nixpkgs.git; rev = "9c927de4b179a6dd210dd88d34bda8af4b575680"; }; nixpkgs = fetchGit { url = https://github.com/NixOS/nixpkgs.git; ref = "release-17.09"; rev = "66b4de79e3841530e6d9c6baf98702aa1f7124e4"; }; in (import (nix + "/release.nix") { inherit nix nixpkgs; }).build.x86_64-linux )' The goal is to enable completely reproducible and traceable evaluation. For example, a NixOS configuration could be fully described by a single Git commit hash. 'nixos-rebuild' would do something like nix build --pure-eval '( (import (fetchGit { url = file:///my-nixos-config; rev = "..."; })).system ') where the Git repository /my-nixos-config would use further fetchGit calls or Git externals to fetch Nixpkgs and whatever other dependencies it has. Either way, the commit hash would uniquely identify the NixOS configuration and allow it to reproduced.

Also, don't depend on tput (ncurses). It's really not needed since ANSI escape sequences have been standardized for 35 years or so.

This fixed the build on ubuntu/debian, where dash is the sh.
2017-10-03More elegant test outputDan Peebles
I got sick of trying to find the failures in the sea of debug output, so we now: - Hide test output unless it fails - Sprinkle in some simple color - Pad results for a more tabular look If Nix is getting a more friendly user interface, we might as well get a friendlier developer interface, right? :)

This reverts commit f78126bfd6b6c8477fcdbc09b2f98772dbe9a1e7. There really is no need for such a massive change...

2014-02-04GNU Make 3.81 compatibilityEelco Dolstra
3.81 doesn't understand the ‘define foo =’ syntax, which was added in 3.82. So use ‘define foo’ instead.
