2019-12-10Make the Store API more type-safeEelco Dolstra
Most functions now take a StorePath argument rather than a Path (which is just an alias for std::string). The StorePath constructor ensures that the path is syntactically correct (i.e. it looks like <store-dir>/<base32-hash>-<name>). Similarly, functions like buildPaths() now take a StorePathWithOutputs, rather than abusing Path by adding a '!<outputs>' suffix. Note that the StorePath type is implemented in Rust. This involves some hackery to allow Rust values to be used directly in C++, via a helper type whose destructor calls the Rust type's drop() function. The main issue is the dynamic nature of C++ move semantics: after we have moved a Rust value, we should not call the drop function on the original value. So when we move a value, we set the original value to bitwise zero, and the destructor only calls drop() if the value is not bitwise zero. This should be sufficient for most types. Also lots of minor cleanups to the C++ API to make it more modern (e.g. using std::optional and std::string_view in some places).

This allows distinguishing between an empty value and no value.

All plugins in plugin-files will be dlopened, allowing them to statically construct instances of the various Register* types Nix supports.

Also, random cleanup to argument handling.

2017-07-03Replace a few bool flags with enumsEelco Dolstra
Functions like copyClosure() had 3 bool arguments, which creates a severe risk of mixing up arguments. Also, implement copyClosure() using copyPaths().

This reverts commit f78126bfd6b6c8477fcdbc09b2f98772dbe9a1e7. There really is no need for such a massive change...

2016-08-29nix path-info: Add --json flagEelco Dolstra
Also, factor out JSON generation from value-to-json.{cc,hh}, and support producing indented JSON.
2016-08-23nix build: Use Nix search pathEelco Dolstra
That is, unless --file is specified, the Nix search path is synthesized into an attribute set. Thus you can say $ nix build nixpkgs.hello assuming $NIX_PATH contains an entry of the form "nixpkgs=...". This is more verbose than $ nix build hello but is less ambiguous.
2016-06-02Allow setting the state directory as a store parameterEelco Dolstra

2016-04-25Improved logging abstractionEelco Dolstra
This also gets rid of --log-type, since the nested log type isn't useful in a multi-threaded situation, and nobody cares about the "pretty" log type.

Implement floats
2016-02-04Eliminate the "store" global variableEelco Dolstra
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.)
2016-01-05First hit at providing support for floats in the language.Christian Theune
2015-11-21Print license information on '--xml --meta'Pascal Wittmann
The nixpkgs manual prescribes the use of values from stdenv.lib.licenses for the meta.license attribute. Those values are attribute sets and currently skipped when running nix-env with '--xml --meta'. This has the consequence that also nixpkgs-lint will report missing licenses. With this commit nix-env with '--xml --meta' will print all attributes of an attribute set that are of type tString. For example the output for the package nixpkgs.hello is <meta name="license" type="strings"> <string type="url" value="http://spdx.org/licenses/GPL-3.0+" /> <string type="shortName" value="gpl3Plus" /> <string type="fullName" value="GNU General Public License v3.0 or later" /> <string type="spdxId" value="GPL-3.0+" /> </meta> This commit fixes nixpkgs-lint, too.

2015-09-17nix-env --upgrade: show "downgrading" when doing soVladimír Čunát
It was strange to show "upgrading" when the version was getting lower. This is left on "upgrading" when the versions are the same, as I can't see any better wording.
2015-09-17nix-env --upgrade: avoid unexpected downgradesVladimír Čunát
Until now, if one explicitly installed a low-priority version, nix-env --upgrade would downgrade it by default and even with --leq. Let's never accept an upgrade with version not matching the upgradeType. Additionally, let's never decrease the priority of an installed package; you can use --install to force that. Also refactor to use variable bestVersion instead of bestName, as only version was used from it.
2015-07-23Optimize small listsEelco Dolstra
The value pointers of lists with 1 or 2 elements are now stored in the list value itself. In particular, this makes the "concatMap (x: if cond then [(f x)] else [])" idiom cheaper.
2015-07-23--version: Print some config infoEelco Dolstra
Such as whether Nix is built with signed binary cache support, and the location of the configuration file.

* only the last generation can be lazy * depend on the '--lazy-generation' flag to be set

new generations if a generation already exists. Alternatively or additionally I propose a mode where only the *last* generation will be sparse.
2015-05-05Allow URLs in the Nix search pathEelco Dolstra
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
