2012-01-03 * Refactoring: Get rid of a few subdirectories in corepkgs/, and someEelco Dolstra1-1/+1
other simplifications. * Use <nix/...> to locate the corepkgs. This allows them to be overriden through $NIX_PATH. * Use bash's pipefail option in the NAR builder so that we don't need to create a temporary file.
2011-08-06 * Add the Nix corepkgs to the end of the search path. This makes itEelco Dolstra1-2/+2
possible for other Nix expressions to use corepkgs (mostly useful for the buildenv function).
2011-08-06 * Allow redirections in search path entries. E.g. if you have aEelco Dolstra1-1/+1
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 * Add a Nix expression search path feature. Paths between angleEelco Dolstra1-0/+3
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.
