From 5d834c40d0a1e397cc650f88b1544ee2e5912400 Mon Sep 17 00:00:00 2001 From: Robert Hensing Date: Wed, 22 Feb 2023 03:28:30 +0100 Subject: flakes: Differentiate `self.outPath` and `self.sourceInfo.outPath` It would be incorrect to say that the `sourceInfo` has an `outPath` that isn't the root. `sourceInfo` is about the root, whereas only the flake may not be about the root. Thanks Eelco for pointing that out. --- src/libexpr/flake/call-flake.nix | 22 +++++++++++++++++----- 1 file changed, 17 insertions(+), 5 deletions(-) (limited to 'src/libexpr/flake/call-flake.nix') diff --git a/src/libexpr/flake/call-flake.nix b/src/libexpr/flake/call-flake.nix index 7dc03e7f5..4beb0b0fe 100644 --- a/src/libexpr/flake/call-flake.nix +++ b/src/libexpr/flake/call-flake.nix @@ -9,16 +9,14 @@ let (key: node: let - rawSourceInfo = + sourceInfo = if key == lockFile.root then rootSrc else fetchTree (node.info or {} // removeAttrs node.locked ["dir"]); subdir = if key == lockFile.root then rootSubdir else node.locked.dir or ""; - outPath = rawSourceInfo + ((if subdir == "" then "" else "/") + subdir); - - sourceInfo = rawSourceInfo // { inherit outPath; }; + outPath = sourceInfo + ((if subdir == "" then "" else "/") + subdir); flake = import (outPath + "/flake.nix"); @@ -47,7 +45,21 @@ let outputs = flake.outputs (inputs // { self = result; }); - result = outputs // sourceInfo // { inherit inputs; inherit outputs; inherit sourceInfo; _type = "flake"; }; + result = + outputs + # We add the sourceInfo attribute for its metadata, as they are + # relevant metadata for the flake.
