v1.8.0 - Source-Based Hot-Reload for BSD

What's New

🔄 Source-Based Hot-Reload Updates

Perfect for BSD systems and custom builds! No more running VMs just to compile binaries.

New Features:

• Build from Source: Automatically git pull and go build when updating
• BSD Compatible: Works on FreeBSD, OpenBSD, NetBSD, and other Unix-like systems
• Progress Updates: See each step of the build process in Discord
• Safe Updates: Stashes local changes and restores old binary if build fails
• No VM Required: Build natively on your BSD system

Configuration

Add to your config.json:

{
  "features": {
    "update_from_source": true
  }
}

Requirements for Source-Based Updates

• Git must be installed
• Go 1.21+ must be installed
• Must be running from a cloned git repository
• GCC required (for go-sqlite3 compilation)

How It Works

1. Check: git fetch to check for new commits
2. Stash: Saves any local changes automatically
3. Pull: git pull to get latest code
4. Build: go build to compile new binary
5. Replace: Swaps old binary with new one
6. Relaunch: Restarts bot automatically

Usage

# Check for source updates
/update check

# Pull and rebuild from source  
/update apply

# View current version and update method
/update version

The update method will show "Build from Source" when enabled.

Traditional Binary Updates Still Work

If update_from_source is false (default), the bot will continue to download pre-compiled binaries as before. This is the recommended method for Linux and Windows systems.

v1.7.2 - Bug Fix: Ban Command Display

Bug Fixes

🔧 Ban Commands Display Names Correctly

Fixed an issue where ban-by-ID commands would show asterisks (*****) or the raw user ID instead of the actual username in confirmation messages.

Affected Commands:

• hackban - Now displays "Username (ID)" instead of just the ID
• unban - Fetches and displays username instead of mention format
• botban - Displays username/server name for user/server bans
• botunban - Shows proper username/server name

How it works:
The bot now uses Discord's API (s.User() / s.Guild()) to fetch the username or server name when you ban by ID. If the fetch fails, it gracefully falls back to showing just the ID.

Example:

• Before: User * has been banned
• After: Username (123456789012345678) has been banned
