Sometimes, "expected" can be "0", but in fact means "unknown". This is for example the case when downloading a file while the http server doesn't send the `Content-Length` header, like when running `nix build` pointing to a nixpkgs checkout streamed from GitHub: ⇒ nix build -f https://github.com/NixOS/nixpkgs/archive/master.tar.gz hello [1.8/0.0 MiB DL] downloading 'https://github.com/NixOS/nixpkgs/archive/master.tar.gz' In that case, don't show that weird progress bar, but only the (slowly increasing) downloaded size ("done"). ⇒ nix build -f https://github.com/NixOS/nixpkgs/archive/master.tar.gz hello [1.8 MiB DL] downloading 'https://github.com/NixOS/nixpkgs/archive/master.tar.gz' This commit also updates fmt calls with three numbers (when something is currently 'running' too) - I'm not sure if this can be provoked, but showing "0" as expected doesn't make any sense, as we're obviously doing more than nothing.
Nix, the purely functional package manager
Nix is a new take on package management that is fairly unique. Because of its purity aspects, a lot of issues found in traditional package managers don't appear with Nix.
To find out more about the tool, usage and installation instructions, please read the manual, which is available on the Nix website at http://nixos.org/nix/manual.
