# flake-compat
|
||||
|
||||
## Usage
|
||||
|
||||
To use, add the following to your `flake.nix`:
|
||||
|
||||
```nix
|
||||
inputs.flake-compat = {
|
||||
url = "github:edolstra/flake-compat";
|
||||
flake = false;
|
||||
};
|
||||
```
|
||||
|
||||
Afterwards, create a `default.nix` file containing the following:
|
||||
|
||||
```nix
|
||||
(import
|
||||
(
|
||||
let lock = builtins.fromJSON (builtins.readFile ./flake.lock); in
|
||||
fetchTarball {
|
||||
url = "https://github.com/edolstra/flake-compat/archive/${lock.nodes.flake-compat.locked.rev}.tar.gz";
|
||||
sha256 = lock.nodes.flake-compat.locked.narHash;
|
||||
}
|
||||
)
|
||||
{ src = ./.; }
|
||||
).defaultNix
|
||||
```
|
||||
|
||||
If you would like a `shell.nix` file, create one containing the above, replacing `defaultNix` with `shellNix`.
