Note

1. This program relies heavily on Steam's internal file formats (VDF files like libraryfolders.vdf, appmanifest_*.acf, loginusers.vdf, and localconfig.vdf). These are undocumented formats that Valve could change at any time, which would break this program's functionality.

2. I used this project to learn Rust, so likely not the most idiomatic :)

3. It's unlikely I'll be taking contributions, but feel free to fork!

Library API

The core library can be used independently of the TUI:

use steamtrain::{Install, Library, App};

// Find Steam installation and all libraries
let install = Install::find()?;

// List all games in a library
for lib in &install.libraries {
    let apps = lib.apps()?;
    for app in apps {
        println!("{}: {} ({})", app.app_id, app.name, app.game_path.display());
    }
}

// Search for a game
let results = install.libraries[0].search_by_name("Dark Souls")?;

// Launch a game
results[0].launch(&[])?;
