+# JMusicBot Fork
+
+A self-hosted Discord music bot fork based on JMusicBot, updated to keep working on modern Discord and JDA versions.
+
+This repository keeps the bot practical to run today, while also adding fork-specific features such as status messages and playback analytics logging. Possibly more.
+

+    - Optional per-channel playback status message
+    - Optional JDBC/SQLite playback analytics logging
+- Basic QoL improvements, such as:
+    - Docker image and container-friendly deployment path
 
-# This fork
+## Quick Links
 
-We had to update to JDA 6, switch to jda-chewtils to make the bot work again.
-Also, we somewhat regularly bump  [lavaplayer](https://mvnrepository.com/artifact/dev.arbjerg/lavaplayer)/[lavalink](https://maven.lavalink.dev/#/releases/dev/lavalink/youtube/common) to their new versions. I will try to update this automatically in the future.

+## Features
 
-### Support for logging into your (burner) youtube account:
+- Easy self-hosting
+- Fast song loading
+- Smooth playback
+- DJ role and server-specific settings
+- Queue management and playlist support
+- Support for many sources, streams, and local files
 
-[PR-1670](https://github.com/jagrosh/MusicBot/pull/1670)
+## Supported Sources And Formats
 
-### To allow building the project from source
-[PR-1703](https://github.com/jagrosh/MusicBot/pull/1703)
+JMusicBot supports all sources and formats supported by [lavaplayer](https://github.com/sedmelluq/lavaplayer#supported-formats).
 
-### Add YouTube PO token & IP rotation
-https://github.com/jagrosh/MusicBot/pull/1772
+Sources:
+- YouTube
+- SoundCloud
+- Bandcamp
+- Vimeo
+- Twitch streams
+- Local files
+- HTTP URLs
 
+Formats:
+- MP3
+- FLAC
+- WAV
+- Matroska/WebM
+- MP4/M4A
+- OGG streams
+- AAC streams
+- Stream playlists such as M3U and PLS
 
-### For PO_Tokens: In your bot folder, edit "config.txt" and add
-```
-ytpotoken = "PO_TOKEN_HERE"
-ytvisitordata = "VISITOR_DATA_HERE"
-```
+## Setup Notes
 
-To get po_token and visitor_data, use [youtube-trusted-session-generator](https://github.com/iv-org/youtube-trusted-session-generator)
+If you only need the essentials:
 
+1. Create a Discord bot and get its token, see [here](https://jmusicbot.com/getting-a-bot-token/).
+2. Enable the `MESSAGE_CONTENT` intent in the Discord Developer Portal [here](https://discord.com/developers/applications) ([Wiki link](https://jda.wiki/using-jda/gateway-intents-and-member-cache-policy/)).
+3. Configure `config.txt`.
+4. Run the jar directly or use Docker.
 
-If you have problems with this fork, you could also check out [this other fork](https://github.com/SeVile/MusicBot).
+For the detailed version, see [docs/setup.md](/git/MusicBot/docs/setup.md).
 
-## Requirements for 0.5+ and above
+## Docker
 
-Since we updated JDA from version 4 to 6 to fix various issues, we had to enable the MESSAGE_CONTENT intent. If you let your bot join more than 100 servers(guilds), you now need to enable this intent in the [Discord Developer Portal](https://discord.com/developers/applications).
-More information can be found in the [JDA documentation](https://jda.wiki/using-jda/gateway-intents-and-member-cache-policy/).
-Note, however, that this is a privileged intent and will require a valid use-case for your bot to be verified in over 75 servers (it will only show up in the portal when on at least 76 servers according to the documentation).
+A Docker image is published here: [docker.io/chrisb09/jmusicbot](https://hub.docker.com/r/chrisb09/jmusicbot)
 
-## Easy deployment via docker
+For compose examples and deployment notes, see [docs/docker.md](/git/MusicBot/docs/docker.md).
 
-Additionally, i thought a corresponding docker image would make things better:
+## YouTube Login
 
-The image can be found on [dockerhub](https://hub.docker.com/repository/docker/chrisb09/jmusicbot/general)
+This fork supports Google account login for YouTube playback workarounds.
 
-Docker-compose:
-
-```yaml
-version: '2.2'
-
-services:
-  jmusicbot:
-    image: chrisb09/jmusicbot:latest
-    container_name: jmusicbot
-    restart: unless-stopped
-    volumes:
-     - ./config:/jmb/config
-```
-
-although, obviously you should change `./config` to whatever path is right for your setup.
-Source code for the docker image is also on [Github](https://github.com/chrisb09/jmb-container).
-
-### Windows
-
-If you want to run the bot on a windows host without docker, you obviously need to install java, and if you want to run it in the background something like [nssm](http://nssm.cc/) can be helpful.
-
-
-## YouTube-Login
-
-Obviously you still need to log in if you want to use youtube properly, hence you need to enable this in the config.
-If you are using a pre-existing config, simply add:
-```
-/ If you set this to true, the bot will use a Google account to play YouTube tracks.
-// This is only needed if you are experiencing issues with YouTube playback.
-// Once enabled, instructions for login will be written to the console and DMs.
-// DO NOT use your main Google account! Use an alternative account.
+Enable:
 
+```conf
 youtubeoauth2=true
 ```
 
-If you start with a clean slate this line should already be present, albeit with `false` being the default.
-As the author of the PR reiterates multiple times, do not use your main google account as using your account for a bot is most certainly against the ToS and thus you are endangering said account.
+Do not use your main Google account. Use a burner or otherwise disposable account instead.
 
-To add the account you simply have to follow the very basic instructions printed either in the console or sent to you from the bot via discord after you have started it, open the linked google page and paste the code.
+More details are in [docs/setup.md](/git/MusicBot/docs/setup.md).
 
-# JMusicBot
+If you use PO tokens or visitor data for YouTube, those details are also covered in [docs/setup.md](/git/MusicBot/docs/setup.md).

+## DAVE / Voice Encryption
 
-A cross-platform Discord music bot with a clean interface, and that is easy to set up and run yourself!
+Discord currently requires DAVE for voice on modern API versions. This fork configures `libdave-jvm` during startup and bundles native binaries for common Linux, Windows, and macOS targets.
 
-[![Setup](http://i.imgur.com/VvXYp5j.png)](https://jmusicbot.com/setup)
+If you deploy on an unsupported architecture, add the matching native dependency in [pom.xml](/git/MusicBot/pom.xml). You probably need to build the library from source for your architecture, so have fun with that.
 
-## Features
-  * Easy to run (just make sure Java is installed, and run!)
-  * Fast loading of songs
-  * No external keys needed (besides a Discord Bot token)
-  * Smooth playback
-  * Server-specific setup for the "DJ" role that can moderate the music
-  * Clean and beautiful menus
-  * Supports many sites, including Youtube, Soundcloud, and more
-  * Supports many online radio/streams
-  * Supports local files
-  * Playlist support (both web/youtube, and local)
+## Upstream And Related Work
 
-## Supported sources and formats
-JMusicBot supports all sources and formats supported by [lavaplayer](https://github.com/sedmelluq/lavaplayer#supported-formats):
-### Sources
-  * YouTube
-  * SoundCloud
-  * Bandcamp
-  * Vimeo
-  * Twitch streams
-  * Local files
-  * HTTP URLs
-### Formats
-  * MP3
-  * FLAC

-## Questions/Suggestions/Bug Reports
-**Please read the [Issues List](https://github.com/jagrosh/MusicBot/issues) before suggesting a feature**. If you have a question, need troubleshooting help, or want to brainstorm a new feature, please start a [Discussion](https://github.com/jagrosh/MusicBot/discussions). If you'd like to suggest a feature or report a reproducible bug, please open an [Issue](https://github.com/jagrosh/MusicBot/issues) on this repository. If you like this bot, be sure to add a star to the libraries that make this possible: [**JDA**](https://github.com/DV8FromTheWorld/JDA) and [**lavaplayer**](https://github.com/sedmelluq/lavaplayer)!
+## Questions And Contributions
 
-## Editing
-This bot (and the source code here) might not be easy to edit for inexperienced programmers. The main purpose of having the source public is to show the capabilities of the libraries, to allow others to understand how the bot works, and to allow those knowledgeable about java, JDA, and Discord bot development to contribute. There are many requirements and dependencies required to edit and compile it, and there will not be support provided for people looking to make changes on their own. Instead, consider making a feature request (see the above section). If you choose to make edits, please do so in accordance with the Apache 2.0 License.
+If you run into issues, please include:
+
+- the version you are running
+- whether you are using Docker or the jar directly
+- relevant config changes
+- relevant logs
+
+Fork-specific version notes live in [docs/fork-changelog.md](/git/MusicBot/docs/fork-changelog.md), which should help with troubleshooting and migration as the fork evolves.

+# Docker Guide
+
+This fork supports running the bot in Docker, which is usually the easiest deployment path for a server.
+
+## Image
+
+Published image:
+
+- [docker.io/chrisb09/jmusicbot](https://hub.docker.com/r/chrisb09/jmusicbot)
+
+Container build sources:
+
+- [github.com/chrisb09/jmb-container](https://github.com/chrisb09/jmb-container)
+
+## Minimal Compose Example
+
+```yaml
+version: "2.2"
+
+services:
+  jmusicbot:
+    image: chrisb09/jmusicbot:latest
+    container_name: jmusicbot
+    restart: unless-stopped
+    volumes:
+      - ./config:/jmb/config
+```
+
+Replace `./config` with the host path you actually want to use.
+
+## Config Files
+
+Your persistent bot config should live in the mounted config directory. That lets you redeploy containers without losing your bot settings.
+
+Typical things to configure there:
+
+- bot token
+- owner ID
+- prefix
+- YouTube login toggle
+- YouTube PO token and visitor-data values if needed
+- status message toggle
+- analytics logging settings
+
+## Deploy Flow
+
+A typical update flow is:
+
+1. Pull or rebuild the image.
+2. Restart the container.
+3. Check logs for startup errors.
+
+Useful commands:
+
+```bash
+docker-compose up -d
+docker-compose logs -f jmusicbot
+```
+
+## Alpine / musl Note
+
+This fork bundles native support for Alpine-compatible musl environments as part of its DAVE setup, so Alpine-based container deployments are supported.
+
+## SQLite Logging In Docker
+
+If you enable analytics logging with SQLite:
+
+```conf
+dblog.enabled = true
+dblog.jdbc_url = "jdbc:sqlite:musicbot.db"
+```
+
+make sure the database file lives somewhere inside your mounted persistent config or data path if you want it to survive container recreation.
+
+## YouTube Token Notes In Docker
+
+If you use YouTube login or PO token based configuration, keep those values in your persistent mounted config rather than baking them into the image.
+
+Relevant config values include:
+
+```conf
+youtubeoauth2 = true
+ytpotoken = "PO_TOKEN_HERE"
+ytvisitordata = "VISITOR_DATA_HERE"
+```
+
+## Recommendation
+
+For production-style use, Docker is the cleanest path if you want:
+
+- reproducible runtime behavior
+- simple upgrades
+- easier separation between bot code and persistent config

+# Fork Changelog
+
+This file tracks fork-specific changes that are useful to operators and contributors. It is not meant to replace commit history, but to summarize what changed at a higher level.
+
+## 0.6.3
+
+- Added JDBC-backed playback analytics logging.
+- Added SQLite as the default logging backend.
+- Logged queue, playback, listener, search, skip, and command activity.
+- Added `dblog.*` config settings to enable and configure logging.
+
+Config:
+
+```conf
+dblog.enabled = true
+dblog.jdbc_url = "jdbc:sqlite:musicbot.db"
+dblog.user = ""
+dblog.password = ""
+```
+
+By default, logging is disabled.
+
+## 0.6.2
+
+- Fixed several status-message race conditions and repost issues.
+- Added debug logging around status-message creation, editing, deletion, and repost flow.
+- Added a config toggle to disable the status-message feature entirely.
+
+Config:
+
+```conf
+statusmessages = true
+```
+
+Set it to `false` to disable the feature.
+
+## 0.6.1
+
+- Bumped the fork version after the initial status-message work had landed.
+
+## 0.6.0
+
+- Updated the bot for modern JDA and Discord requirements.
+- Added DAVE voice support required for current Discord voice playback.
+- Continued dependency refreshes for lavaplayer and related components.
+- Carried forward work related to YouTube login, PO token handling, and buildability on the newer stack.
+
+Imported work included in this fork:
+
+- PR-1670, support for logging into a YouTube account, is included from `0.4.5` onward.
+- PR-1703, changes to allow building the project from source more easily, is included from `0.4.5` onward.
+- `jagrosh#1772`, YouTube PO token and IP rotation support, is included from `0.4.7` onward.
+
+## Notes
+
+- This fork may move faster than upstream in areas related to Discord API compatibility and deployment practicality.

+# Setup Guide
+
+This guide covers the normal non-Docker setup path and the main configuration points that matter on this fork.
+
+## Prerequisites
+
+- Java 11 or newer
+- A Discord bot token
+- A Discord application with the bot invited to your server
+
+## Discord Setup
+
+1. Create a bot in the [Discord Developer Portal](https://discord.com/developers/applications).
+2. Copy the bot token.
+3. Enable the `MESSAGE_CONTENT` intent.
+
+This intent is required for command-based bots like this one.
+
+## Privileged Intent Notes
+
+This fork moved from JDA 4 to JDA 6, so `MESSAGE_CONTENT` is now an important operational requirement for the classic text-command flow.
+
+Keep in mind:
+
+- If the bot joins more than 100 servers, this intent must be enabled in the [Discord Developer Portal](https://discord.com/developers/applications).
+- `MESSAGE_CONTENT` is a privileged intent.
+- Discord verification requirements become relevant as the bot grows.
+- The related portal controls historically only become visible once the application is already in a fairly large number of servers.
+
+For the broader Discord/JDA behavior, see the [JDA gateway intents documentation](https://jda.wiki/using-jda/gateway-intents-and-member-cache-policy/).
+
+## First Configuration
+
+The bot reads from `config.txt` using the values defined in [reference.conf](/git/MusicBot/src/main/resources/reference.conf).
+
+The minimum settings you should care about first are:
+
+```conf
+token = "YOUR_BOT_TOKEN"
+owner = 123456789012345678
+prefix = "@mention"
+```
+
+Useful fork-specific options:
+
+```conf
+youtubeoauth2 = true
+statusmessages = true
+dblog.enabled = false
+```
+
+You may also need these for YouTube PO token support:
+
+```conf
+ytpotoken = "PO_TOKEN_HERE"
+ytvisitordata = "VISITOR_DATA_HERE"
+```
+
+## Running The Bot
+
+Build:
+
+```bash
+mvn clean package
+```
+
+Run:
+
+```bash
+java -jar target/JMusicBot-*-All.jar
+```
+
+This fork includes changes to keep source builds practical on the newer stack as well.
+
+## YouTube Login
+
+If YouTube playback is unreliable, enable:
+
+```conf
+youtubeoauth2 = true
+```
+
+After startup, the bot prints instructions and sends the owner a DM with the authorization flow.
+
+Important:
+
+- Do not use your main Google account.
+- Use a burner or otherwise disposable account.
+
+If you are starting from a clean config, this option should already exist with a default of `false`.
+
+## YouTube PO Tokens And Visitor Data
+
+This fork also supports explicit YouTube PO token and visitor-data configuration.
+
+Config:
+
+```conf
+ytpotoken = "PO_TOKEN_HERE"
+ytvisitordata = "VISITOR_DATA_HERE"
+```
+
+You can generate these values with:
+
+- [iv-org/youtube-trusted-session-generator](https://github.com/iv-org/youtube-trusted-session-generator)
+
+This is useful when normal YouTube playback is not enough and you need a more explicit trusted-session style setup.
+
+## DAVE / Voice Support
+
+This fork includes DAVE support for current Discord voice requirements. In normal supported environments, nothing extra is required beyond using the provided shaded jar.
+
+If you run on an unsupported architecture, add the correct native `libdave-jvm` dependency in [pom.xml](/git/MusicBot/pom.xml).
+
+Bundled native targets include:
+
+- Linux glibc x86_64
+- Linux musl x86_64
+- Windows x86_64
+- macOS
+
+## Status Messages
+
+The bot can maintain a single playback status message in the active text channel.
+
+Config:
+
+```conf
+statusmessages = true
+```
+
+Disable it with:
+
+```conf
+statusmessages = false
+```
+
+## Analytics Logging
+
+Playback analytics logging is off by default.
+
+Enable SQLite logging:
+
+```conf
+dblog.enabled = true
+dblog.jdbc_url = "jdbc:sqlite:musicbot.db"
+```
+
+This creates a local SQLite database file and records queue, playback, listener, and command activity.
+
+## Windows Note
+
+If you run the bot directly on Windows rather than in Docker, install Java first and consider a service wrapper such as [NSSM](http://nssm.cc/) if you want it to run in the background.
+
+## Related Fork Context
+
+This fork incorporates or builds on work related to:
+
+- [PR-1670](https://github.com/jagrosh/MusicBot/pull/1670) for YouTube account login support
+- [PR-1703](https://github.com/jagrosh/MusicBot/pull/1703) for source builds
+- [PR-1772](https://github.com/jagrosh/MusicBot/pull/1772) for YouTube PO token and IP rotation work
+
+If this fork does not fit your setup, another fork you may want to inspect is [SeVile/MusicBot](https://github.com/SeVile/MusicBot).
