Examples

#[tokio::main]
async fn main() -> Result<()> {
  // Lookup for manifest and load it
  // We will later use `spuz_folder` for this once it is ready
  let manifest = todo!();

  // Use global java
  // Later we will use a local installation with right version
  let mut builder = CommandBuilder::new("java");
  // Apply allocation arguments: -Xms1024m -Xmx4096m
  builder.apply(AllocRange(1024..4096));

  // Setup launcher wrench
  let wrench = LauncherWrench::builder()
    .manifest(&manifest)
    .current_dir(&root)
    .game_dir(&game_dir)
    .build();

  // Apply wrench
  builder.apply(wrench);
  // Apply player settings
  builder.apply(Player::new("LIMPIX31", "268903ca-7946-400a-8984-1fdc0b8baf71"));
  // Window size
  builder.apply(WindowSize::new(1280, 720));
  // Set if you want start in fullscreen mode
  // builder.apply(Fullscreen);

  // Build and spawn process
  let process = builder.build().spawn()?;

  // Watch for logs
  while let Ok(log) = process.logs.recv().await {
    print!("{log}");
  }

  Ok(())
