Sometimes it can be useful to build the image _outside_ of the Nix sandbox for debugging purposes.
For this purpose we have an attribute called `impureMode` which outputs the shell script used by Nix inside the sandbox to build the image.
Usage with Nix Flakes
---------------------
Build the demo by running:
```shell
nix build .#demoImage
```
This project's **flake.nix** exposes its functions under `lib`. To use
in your own project, setup your flake like this:
```nix
{
inputs = {
nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
wfvm.url = "git+https://git.m-labs.hk/m-labs/wfvm";
};
outputs = { self, nixpkgs, wfvm }: {
packages."x86_64-linux".flaky-os = wfvm.lib.makeWindowsImage {
# configuration parameters go here
};
};
}
```
