2020-04-10Remove flake 'edition' fieldEelco Dolstra
Future editions of flakes or the Nix language can be supported by renaming flake.nix (e.g. flake-v2.nix). This avoids a bootstrap problem where we don't know which grammar to use to parse flake*.nix. It also allows a project to support multiple flake editions, in theory.
2020-04-06nix flake info: Show resolved URLEelco Dolstra
This is useful for finding out what a registry lookup resolves to, e.g $ nix flake info patchelf Resolved URL: github:NixOS/patchelf Locked URL: github:NixOS/patchelf/cd7955af31698c571c30b7a0f78e59fd624d0229
2020-04-06nix flake info --json: Don't evaluateEelco Dolstra
This makes its behaviour consistent with the non-json variant. Querying the outputs should be done by another command (e.g. 'nix search')

2020-04-01Registry: Use a struct instead of a tuple for entriesEelco Dolstra
2020-04-01Add a system-wide flake registry /etc/nix/registry.jsonEelco Dolstra
One application for this is pinning the 'nixpkgs' flake to the exact revision used to build the NixOS system, e.g. { "flakes": [ { "from": { "id": "nixpkgs", "type": "indirect" }, "to": { "owner": "NixOS", "repo": "nixpkgs", "type": "github", "rev": "b0c285807d6a9f1b7562ec417c24fa1a30ecc31a" } } ], "version": 2 }

2020-01-30Use std::nulloptEelco Dolstra
2020-01-30Add 'nix flake archive' commandEelco Dolstra
This copies a flake and all its inputs recursively to a store (e.g. a binary cache). This is intended to enable long-term reproducibility for flakes. However this will also require #3253. Example: $ nix flake archive --json --to file:///tmp/my-cache nixops {"path":"/nix/store/272igzkgl1gdzmabsjvb2kb2zqbphb3p-source","inputs":{"nixops-aws":{"path":"/nix/store/ybcykw13gr7iq1pzg18iyibbcv8k9q1v-source","inputs":{}},"nixops-hetzner":{"path":"/nix/store/6yn0205x3nz55w8ms3335p2841javz2d-source","inputs":{}},"nixpkgs":{"path":"/nix/store/li3lkr2ajrzphqqz3jj2avndnyd3i5lc-source","inputs":{}}}} $ ll /tmp/my-cache total 16 -rw-r--r-- 1 eelco users 403 Jan 30 01:01 272igzkgl1gdzmabsjvb2kb2zqbphb3p.narinfo -rw-r--r-- 1 eelco users 403 Jan 30 01:01 6yn0205x3nz55w8ms3335p2841javz2d.narinfo -rw-r--r-- 1 eelco users 408 Jan 30 01:01 li3lkr2ajrzphqqz3jj2avndnyd3i5lc.narinfo drwxr-xr-x 2 eelco users 6 Jan 30 01:01 nar -rw-r--r-- 1 eelco users 21 Jan 30 01:01 nix-cache-info -rw-r--r-- 1 eelco users 404 Jan 30 01:01 ybcykw13gr7iq1pzg18iyibbcv8k9q1v.narinfo Fixes #3336.
2020-01-29Clean up the lock file handling flagsEelco Dolstra
Added a flag --no-update-lock-file to barf if the lock file needs any changes. This is useful for CI systems if you're building a checkout. Fixes #2947. Renamed --no-save-lock-file to --no-write-lock-file. It is now a fatal error if the lock file needs changes but --no-write-lock-file is not given.
2020-01-29Add flag --override-input to override specific lock file entriesEelco Dolstra
E.g. $ nix flake update ~/Misc/eelco-configurations/hagbard \ --override-input 'dwarffs/nixpkgs' ../my-nixpkgs overrides the 'nixpkgs' input of the 'dwarffs' input of the top-level flake. Fixes #2837.
2020-01-22resolveFlake -> lockFlakeEelco Dolstra
"resolve" is ambiguous (also used for registry resolution).

2019-10-15Support non-x86_64-linux system types in flakesEelco Dolstra
A command like $ nix run nixpkgs#hello will now build the attribute 'packages.${system}.hello' rather than 'packages.hello'. Note that this does mean that the flake needs to export an attribute for every system type it supports, and you can't build on unsupported systems. So 'packages' typically looks like this: packages = nixpkgs.lib.genAttrs ["x86_64-linux" "i686-linux"] (system: { hello = ...; }); The 'checks', 'defaultPackage', 'devShell', 'apps' and 'defaultApp' outputs similarly are now attrsets that map system types to derivations/apps. 'nix flake check' checks that the derivations for all platforms evaluate correctly, but only builds the derivations in 'checks.${system}'. Fixes #2861. (That issue also talks about access to ~/.config/nixpkgs and --arg, but I think it's reasonable to say that flakes shouldn't support those.) The alternative to attribute selection is to pass the system type as an argument to the flake's 'outputs' function, e.g. 'outputs = { self, nixpkgs, system }: ...'. However, that approach would be at odds with hermetic evaluation and make it impossible to enumerate the packages provided by a flake.
