import <a.nix> + import <b.nix> + import <c.nix> + import <dir5/c.nix>
* Allow redirections in search path entries. E.g. if you have a directory /home/eelco/src/stdenv-updates that you want to use as the directory for import such as with (import <nixpkgs> { }); then you can say $ nix-build -I nixpkgs=/home/eelco/src/stdenv-updates 2011-08-06 19:48:57 +02:00			`import <a.nix> + import <b.nix> + import <c.nix> + import <dir5/c.nix>`
* 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 18:05:24 +02:00
