Crate lolrofl 

Rust library and tool to parse and inspect ROFL replay files generated from League of Legends games.

Backward-compatibility for replay files is NOT to be expected as of now.

Usage as a command-line tool

After building with cargo install --bin lolrofl --features "clap json payload", a new lolrofl executable become available.

Said executable allows the inspection of ROFL files to extract game information, metadata, or development intel with the following commands:

• get: Get high-level information on the file
  • get info: Print simple/high-level info on the file and the game
  • get metadata: Print the game’s metadata
  • get payload: Print technical information on the file
• analyze: Get low-level information on the file - usually for debug and development purpose
• export: Export chunk or keyframe data to a file or directory

Usage as a library

Use lolrofl to parse a loaded file’s content :

// let content = std::fs::read(source_file).unwrap();
// Parse the file's content with Rofl
let data = lolrofl::Rofl::from_slice(&content[..]).unwrap();

// Print the file's length as specified within the file (this may not match the actual file size if it is incomplete or corrupted)
println!("Expected file length: {:?} bytes", data.head().file_len());
// Print the file's metadata (a JSON string)
println!("{}", data.metadata().unwrap());
// Print information on the game without depending on the metadata
let payload = data.payload().unwrap();
println!("The game {} lasted {} seconds", payload.id(), payload.duration()/1000);
