As discussed in #7417, it would be good to make more string values work as installables. That is to say, if an installable refers to a value, and the value is a string, it used to not work at all, since #7484, it works somewhat, and this PR make it work some more. The new cases that are added for `BuiltPath` contexts: - Fixed input- or content-addressed derivation: ``` nix-repl> hello.out.outPath "/nix/store/jppfl2bp1zhx8sgs2mgifmsx6dv16mv2-hello-2.12" nix-repl> :p builtins.getContext hello.out.outPath { "/nix/store/c7jrxqjhdda93lhbkanqfs07x2bzazbm-hello-2.12.drv" = { outputs = [ "out" ]; }; } The string matches the specified single output of that derivation, so it should also be valid. - Floating content-addressed derivation: ``` nix-repl> (hello.overrideAttrs (_: { __contentAddressed = true; })).out.outPath "/1a08j26xqc0zm8agps8anxpjji410yvsx4pcgyn4bfan1ddkx2g0" nix-repl> :p builtins.getContext (hello.overrideAttrs (_: { __contentAddressed = true; })).out.outPath { "/nix/store/qc645pyf9wl37c6qvqzaqkwsm1gp48al-hello-2.12.drv" = { outputs = [ "out" ]; }; } ``` The string is not a path but a placeholder, however it also matches the context, and because it is a CA derivation we have no better option. This should also be valid. We may also want to think about richer attrset based values (also discussed in that issue and #6507), but this change "completes" our string-based building blocks, from which the others can be desugared into or at least described/document/taught in terms of.
