Eelco Dolstra e446d342b7 * Added an installation source --from-expression' (or -E') to ... install derivations from a Nix expression specified on the command line. This is particularly useful for disambiguation if there are multiple derivations with the same name. For instance, in Nixpkgs, to install the Firefox wrapper rather than the plain Firefox component: $ nix-env -f .../i686-linux.nix -i -E 'x: x.firefoxWrapper' The Nix expressions should be functions to which the default Nix expression (in this case, `i686-linux.nix') is passed, hence `x: ...'. This might also be a nice way to deal with high-level (user-level) variability, e.g., $ nix-env -f ./server.nix -i -E 'x: x {port = 8080; ssl = false;}'		2005-02-14 17:07:43 +00:00
