Add constant ‘nixPath’ It contains the Nix expression search path as a list of { prefix, path } sets, e.g. [ { path = "/nix/var/nix/profiles/per-user/root/channels/nixos"; prefix = ""; } { path = "/etc/nixos/configuration.nix"; prefix = "nixos-config"; } { path = "/home/eelco/Dev/nix/inst/share/nix/corepkgs"; prefix = "nix"; } ] 2014-05-26 15:55:47 +03:00			`with import ./lib.nix;`

Move <nix/fetchurl.nix> into the nix binary This makes the statically linked nix binary just work, without needing any additional files. 2020-12-22 15:43:20 +02:00			`assert isFunction (import <nix/fetchurl.nix>);`

Rename nixPath to __nixPath The name ‘nixPath’ breaks existing code. 2014-07-30 12:27:34 +03:00			`assert length (filter (x: baseNameOf x.path == "dir4") __nixPath) == 1;`
* Add a Nix expression search path feature. Paths between angle brackets, e.g. import <nixpkgs/pkgs/lib> are resolved by looking them up relative to the elements listed in the search path. This allows us to get rid of hacks like import "${builtins.getEnv "NIXPKGS_ALL"}/pkgs/lib" The search path can be specified through the ‘-I’ command-line flag and through the colon-separated ‘NIX_PATH’ environment variable, e.g., $ nix-build -I /etc/nixos ... If a file is not found in the search path, an error message is lazily thrown. 2011-08-06 19:05:24 +03:00
* Add the Nix corepkgs to the end of the search path. This makes it possible for other Nix expressions to use corepkgs (mostly useful for the buildenv function). 2011-08-06 21:23:38 +03:00			`import <a.nix> + import <b.nix> + import <c.nix> + import <dir5/c.nix>`
