Overview

Karaoke is a lightweight Python library designed to facilitate interactions with song LRC (Lyric) files. It allows for easy parsing, management, and retrieval of song lyrics along with their corresponding timestamps.

Installation

To use the Karaoke library, simply clone the repository or download the karaoke.py file and include it in your project.

git clone https://github.com/pascall-de-creator/karaoke.py

Features

• Parsing LRC Files: Load and parse LRC formatted lyrics, extracting timestamps and lyrics.
• Timestamp Management: Convert timestamps from LRC format to milliseconds for precise timing.
• Current Lyric Tracking: Keep track of the current lyric based on a given timestamp.

Usage

Importing the Library

from karaoke import Karaoke

Creating an Instance

karaoke = Karaoke()

Parsing LRC Data

To parse LRC data, use the parse method:

lrc_data = """
[00:01.00]Line 1
[00:05.00]Line 2
[00:10.00]Line 3
"""

karaoke.parse(lrc_data)

Accessing Lyrics

You can access all the lyrics using the lyrics property:

all_lyrics = karaoke.lyrics
print(all_lyrics)  # Output: ['Line 1', 'Line 2', 'Line 3']

Getting Current Lyric

To get the currently active lyric based on the timestamp set, use the current_lyric property:

karaoke.set_current_lyric(6000)  # Set current time to 6 seconds
print(karaoke.current_lyric)  # Output: 'Line 2'

Clean and Validate LRC Data

The check method validates the LRC data:

karaoke.check(lrc_data)  # Raises ValueError if the data is invalid

The clean method can be used to clean up LRC data by removing blank lines:

cleaned_lrc = karaoke.clean(lrc_data, clean_blanklines=True)

Timestamp Conversion

Convert LRC timestamp to milliseconds with:

ms = karaoke.timestamp_to_ms("[00:01.00]")  # Output: 1000

Finding Lyric Index

To find the index of a lyric based on the target time:

index = karaoke.find_lyric_index(6000)  # Output: 1

Class Reference

Karaoke

Properties

• lyrics: Returns a list of all lyrics.
• lyric_index: Returns the index of the currently active lyric.
• current_lyric: Returns the currently active lyric.

Methods

• check(lrc: str): Validates the provided LRC data.
• clean(lrc: str, clean_blanklines: bool): Cleans the LRC data by removing timestamps or blank lines.
• timestamp_to_ms(timestamp: str) -> int: Converts LRC timestamp to milliseconds.
• parse(lrc: str, clean_blanklines: bool = False): Parses the LRC data into an internal structure.
• find_lyric_index(target_time: int) -> int: Finds the index of the lyric that corresponds to a given time.
• set_current_lyric(target_time: int): Sets the current lyric based on a target time.

Example

Here's a complete example demonstrating the library's functionality:

from karaoke import Karaoke

karaoke = Karaoke()

lrc_data = """
[00:01.00]Line 1
[00:05.00]Line 2
[00:10.00]Line 3
"""

karaoke.parse(lrc_data)

karaoke.set_current_lyric(6000)  # Set current time to 6 seconds
print(karaoke.current_lyric)  # Output: 'Line 2'

Conclusion

The Karaoke library is a simple yet powerful tool for managing song lyrics and their timestamps. Its clean API and lightweight structure make it easy to integrate into various projects. Enjoy your karaoke sessions!
