	experimental feature is enabled This allows writing fallback code like if builtins ? fetchClosure then builtins.fetchClose { ... } else builtins.storePath ...
2021-09-29	libexpr: throw a more helpful eval-error if a builtin is not available due ↵	Maximilian Bosch
	to a missing feature-flag I found it somewhat confusing to have an error like error: attribute 'getFlake' missing if the required experimental-feature (`flakes`) is not enabled. Instead, I'd expect Nix to throw an error just like it's the case when using e.g. `nix flake` without `flakes` being enabled. With this change, the error looks like this: $ nix-instantiate -E 'builtins.getFlake "nixpkgs"' error: Cannot call 'builtins.getFlake' because experimental Nix feature 'flakes' is disabled. You can enable it via '--extra-experimental-features flakes'. at «string»:1:1: 1\| builtins.getFlake "nixpkgs" \| ^ I didn't use `settings.requireExperimentalFeature` here on purpose because this doesn't contain a position. Also, it doesn't seem as if we need to catch the error and check for the missing feature here since this already happens at evaluation time.

2020-08-24	Allow primops to have Markdown documentation	Eelco Dolstra

2020-06-18	Don't provide 'getFlake' if the 'flakes' feature is not enabled	Eelco Dolstra

2020-04-07	Backport libfetchers from the flakes branch	Eelco Dolstra
	This provides a pluggable mechanism for defining new fetchers. It adds a builtin function 'fetchTree' that generalizes existing fetchers like 'fetchGit', 'fetchMercurial' and 'fetchTarball'. 'fetchTree' takes a set of attributes, e.g. fetchTree { type = "git"; url = "https://example.org/repo.git"; ref = "some-branch"; rev = "abcdef..."; } The existing fetchers are just wrappers around this. Note that the input attributes to fetchTree are the same as flake input specifications and flake lock file entries. All fetchers share a common cache stored in ~/.cache/nix/fetcher-cache-v1.sqlite. This replaces the ad hoc caching mechanisms in fetchGit and download.cc (e.g. ~/.cache/nix/{tarballs,git-revs*}). This also adds support for Git worktrees (c169ea59049f861aaba429f48b828d0820b74d1d).
2018-04-09	Make prim_exec and prim_importNative available to plugins	Shea Levy

2018-02-08	Allow using RegisterPrimop to define constants.	Shea Levy
	This enables plugins to add new constants, as well as new primops.
2016-04-14	Make primop registration pluggable	Eelco Dolstra
	This way we don't have to put all primops in one giant file.
2004-08-04	* Allow primops with more that 1 arguments.	Eelco Dolstra

2004-02-04	* Use a map to lookup primops.	Eelco Dolstra
	* Various performance improvements in the evaluator. * Do not link against unused (and missing!) libraries (-lsglr, etc.).
2003-11-19	* Refactoring: put the Nix expression evaluator in its own library so	Eelco Dolstra
	that it can be used by multiple programs.
