# Idea
Nixcitizen is an attempt to package a wine application in a sensible and
practical way with nix. The idea that the `WINEPREFIX` is handled by a 
script that lives inside the nix store which derives the `WINEPREFIX` from
it's own path inside the store, leading to a creation and setup of a new
`WINEPREFIX` as soon as the script, it's dependencies or any configuration
changes.

The volatile nature of the `WINEPREFIX` leads to challenges in regards
to preservation of needed state, this is handled in the following ways:

* The Application in itself and the launcher folder containing the 
  session data are created in the users home directory and symlinked
  into each prefix.
* Internal wine settings are handled as registry files and automatically
  applied when a new prefix is created.

All dependencies are handled by wine. [dxvk](https://github.com/doitsujin/dxvk)
is compiled with nix and copied into each prefix and fonts are handled in a 
similar manner

# Installation 
First clone this repository, then 

## On nixos
* Put `(pkgs.callPackage ./path/to/repo {  })` into `environment.systemPackages` or
  `users.extraUsers.<name>.packages` or into your home-manager configuration packages

## with nix-env
* plz no!


## Installation parameters
* `installDir`: Contains the `Roberts Space Industries` folder that is being linked
into the `Program Files` folder of the prefixs.
* `launcherCache`: `AppData` folder of the launcher. Holds the session data. 
* `prefixBaseDir`: Where all the prefixes are installed under.
* `binName`: Name of the generated executable.
* `launcherArgs`: Arguments the RSI Launcher is called with.
* `winePackage`: Package of wine to use.
* `wineGlobalEnv`: Global variables that are exported at script startup.
* `winePatches`: List of patches for wine for easier access.
* `virtualDesktop`: `NULL` or a string in the form `AxB` with `A` and `B` being
  positive Integers that define the height and width of the wine virtual desktop.
* `registryFiles`: Additional registry files to add to each prefix.
* `captureMouse`: Whether wine captures fullscreen windows.

## Script parameters
* `--install-prefix`: Installs the prefix if needed.
* `--install-launcher`: Installs the launcher. Can be used to reinstall.
* `--clean`: Deletes all but the currently used prefixes of the game.
* `--remove-prefix`: Deletes the currently used prefix. Use with care.
* `--run-game`:  Runs the game (after installing the prefix if needed). Default behaviour.
* `--print-prefix`: Prints the current prefix path.
