Fetch a flake from a flake reference, and return its output attributes and some metadata. For example:
|
||||
|
||||
```nix
|
||||
(builtins.getFlake "nix/55bc52401966fbffa525c574c14f67b00bc4fb3a").packages.x86_64-linux.nix
|
||||
```
|
||||
|
||||
Unless impure evaluation is allowed (`--impure`), the flake reference
|
||||
must be "locked", e.g. contain a Git revision or content hash. An
|
||||
example of an unlocked usage is:
|
||||
|
||||
```nix
|
||||
(builtins.getFlake "github:edolstra/dwarffs").rev
|
||||
```
|
||||
|
||||
This function is only available if you enable the experimental feature
|
||||
`flakes`.
