### How to use ### How to use
To build Voxygen, run: To build and install Voxygen and the server CLI into user profile, run:
`nix build` ```shell
nix-env -f nix/default.nix -i
```
You can configure what to install by changing the `cratesToBuild` argument:
```shell
nix-env -f nix/default.nix --arg cratesToBuild '["veloren-voxygen"]'
```
For example, this will install Voxygen only.
To build another binary, run: To enter the development shell (which includes all tools mentioned in this readme + tools you'll need to develop Veloren), run:
`nix build --arg crateName "<binary name here>"` ```shell
nix-shell nix/shell.nix
To enter the development shell (which includes all tools mentioned in this readme), run: ```
`nix-shell shell.nix`
### Managing Cargo.nix ### Managing Cargo.nix
Enter the development shell. Enter the development shell.
