Eliminate the "store" global variable Also, move a few free-standing functions into StoreAPI and Derivation. Also, introduce a non-nullable smart pointer, ref<T>, which is just a wrapper around std::shared_ptr ensuring that the pointer is never null. (For reference-counted values, this is better than passing a "T&", because the latter doesn't maintain the refcount. Usually, the caller will have a shared_ptr keeping the value alive, but that's not always the case, e.g., when passing a reference to a std::thread via std::bind.) 2016-02-04 14:28:26 +01:00

Disable TLS verification for builtin fetchurl This makes it consistent with the Nixpkgs fetchurl and makes it work in chroots. We don't need verification because the hash of the result is checked anyway. 2015-10-21 14:59:01 +02:00			`struct DownloadOptions`

StoreAPI -> Store Calling a class an API is a bit redundant... 2016-02-04 14:48:42 +01:00			`class Store;`

Allow URLs in the Nix search path E.g. to install "hello" from the latest Nixpkgs: $ nix-build '<nixpkgs>' -A hello -I nixpkgs=https://nixos.org/channels/nixpkgs-unstable/nixexprs.tar.xz Or to install a specific version of NixOS: $ nixos-rebuild switch -I nixpkgs=https://github.com/NixOS/nixpkgs/archive/63def04891a0abc328b1b0b3a78ec02c58f48583.tar.gz 2015-05-05 17:09:42 +02:00

nix-env/nix-instantiate/nix-build: Support URIs For instance, you can install Firefox from a specific Nixpkgs revision like this: $ nix-env -f https://github.com/NixOS/nixpkgs/archive/63def04891a0abc328b1b0b3a78ec02c58f48583.tar.gz -iA firefox Or build a package from the latest nixpkgs-unstable channel: $ nix-build https://nixos.org/channels/nixpkgs-unstable/nixexprs.tar.xz -A hello 2015-05-06 14:54:31 +02:00			`bool isUri(const string & s);`
