Rosu Pattern Dtector

rosu-pattern-detector is a Rust-based library designed to analyze patterns in osu! beatmaps. It currently supports osu!mania mode exclusively, focusing on detecting specific secondary patterns such as Jack, Jumpstream, Singlestream, and * Handstream*, and tertiary patterns see mania::struct for more info. While osu!mania is the only mode supported right now, the project intends to evolve into a universal tool for analyzing all osu! game modes.

Features

• Current Game Mode Support: osu!mania only.

• Secondary Pattern Analysis:

  • Jack

  • Jumpstream

  • Singlestream

  • Handstream

• Tertiary Pattern Analysis:

Jack Patterns

• Chordjack
• DenseChordjack
• ChordStream
• Speedjack
• All

Jumpstream Patterns

• LightJs
• AnchorJs
• JS
• JT
• All

Handstream Patterns

• LightHs
• AnchorHs
• DenseHs
• HS
• All

Singlestream Patterns

• Singlestream
• All

Extensible Design:

- Although limited to osu!mania for now, the library is structured for future extension to other osu! game modes (osu!standard, taiko, catch) and more advanced patterns.

Installation

In Rust:

Add the library and its dependencies to your Cargo.toml file:

[dependencies]
rosu-map = "0.2.0"
serde = { version = "1.0.217", features = ["derive"] }
serde_json = "1.0.137"
eyre = "0.6.12"

Example JSON Output:

{
  "jack": 14.5,
  "jumpstream": 8.3,
  "singlestream": 12.0,
  "handstream": 5.4
}

Current Limitations

• osu!mania-only:

  • The library currently does not support other osu! modes (osu!standard, taiko, or catch).

• Secondary Patterns Only:

  • Currently, it focuses on detecting only secondary patterns. More advanced tertiary patterns (e.g., polyrhythms, advanced time signature detection) will be added in future releases.

Roadmap

• Support for Other Game Modes:

  • Add compatibility for osu!standard, taiko, and catch.

• Advanced Patterns:

  • Expand functionality to cover more complex patterns.

• Performance Optimizations:

  • Improve computation speed for large and complex maps.
