rosu-noodlers

A Rust library for manipulating long notes (LN) in osu!mania beatmaps.

Features

• Convert all long notes to normal notes (noln)
• Convert all notes to long notes with custom gap and duration (full_ln)
• Convert notes to long notes based on beat divisions (full_ln_beat_divisor)

Installation

Add this to your Cargo.toml:

[dependencies]
rosu-noodlers = "0.1.0"
rosu-map = "0.2.0"

Usage

use rosu_noodlers::{noln, all_ln, full_ln_beat_divisor};
use rosu_map::Beatmap;

// Load a beatmap
let mut map = Beatmap::from_path("path/to/map.osu").unwrap();

// Remove all long notes
noln(&mut map);

// Convert all notes to LNs with 40ms gap and 30ms minimum duration
full_ln(&mut map, 40.0, 30.0);

// Convert notes to LNs based on 1/8 beat division
full_ln_beat_divisor(&mut map, 8.0, None);

// Save the modified beatmap
map.encode_to_path("path/to/output.osu").unwrap();

Requirements

• Rust 1.84.1 or higher
• rosu-map 0.2.0
