Playing Descent 3 using the Nix package manager is a little bit awkward
|
||
at the moment. This wrapper makes it slightly less awkward. Here’s how
|
||
you use this wrapper:
|
||
|
||
1. Install the `descent3` package, or start an ephemeral shell with the
|
||
`descent3` package.
|
||
|
||
2. Find the documentation folder for `descent3-unwrapped` by running this
|
||
command:
|
||
|
||
```bash
|
||
nix-instantiate --eval --expr '(import <nixpkgs> { }).descent3-unwrapped + "/share/doc/Descent3"'
|
||
```
|
||
|
||
3. Open `<descent3-unwrapped-doc-folder>/USAGE.md`.
|
||
|
||
4. Follow steps 1–6 of Descent 3’s usage instructions.
|
||
|
||
5. Change directory into the `D3-open-source` folder:
|
||
|
||
```bash
|
||
cd <path-to-D3-open-source>
|
||
```
|
||
|
||
6. Start Descent 3 by running this command:
|
||
|
||
```bash
|
||
Descent3
|
||
```
|
||
'';
|
||
};
|
||
}
|
||
''
|
||
mkdir --parents "$out/bin"
|
||
descent3_unwrapped=${lib.strings.escapeShellArg descent3-unwrapped}
|
||
makeBinaryWrapper \
|
||
"$descent3_unwrapped/bin/Descent3" \
|
||
"$out/bin/Descent3" \
|
||
--append-flags -additionaldir \
|
||
--append-flags "$descent3_unwrapped/share"
|
||
''
