# Get tracks by specific user
user_tracks = history.get_by_requester(user_id=123456789)
# Navigate through history
previous_track = history.get_previous()
next_track = history.get_next()
# Get all unique tracks (removes duplicates)
unique = history.get_unique_tracks()
# Clear history
history.clear()
```
### Properties

## 💾 Playlist Manager
Export and import playlists to/from JSON and M3U formats.
### Features
- Export queue to JSON
- Import playlists from JSON
- Export to M3U format
- Merge multiple playlists
- Remove duplicates
- Playlist metadata
### Usage
#### Export Queue
```python
import pomice
# Export current queue
pomice.PlaylistManager.export_queue(
player.queue,
filepath='playlists/my_playlist.json',
name='My Awesome Playlist',
description='Best songs ever',
include_metadata=True # Include requester info
)
```
#### Import Playlist
```python
# Import playlist data
data = pomice.PlaylistManager.import_playlist('playlists/my_playlist.json')
# Get just the URIs
uris = pomice.PlaylistManager.get_track_uris('playlists/my_playlist.json')
# Load tracks into queue
for uri in uris:
results = await player.get_tracks(query=uri)
if results:
await player.queue.put(results[0])
```
#### Export Track List
```python
# Export a list of tracks (not from queue)
tracks = [track1, track2, track3]
pomice.PlaylistManager.export_track_list(
tracks,
filepath='playlists/favorites.json',
name='Favorites',
description='My favorite tracks'
)
```
#### Merge Playlists
```python
# Merge multiple playlists into one
pomice.PlaylistManager.merge_playlists(
filepaths=['playlist1.json', 'playlist2.json', 'playlist3.json'],
output_path='merged_playlist.json',
name='Mega Playlist',
remove_duplicates=True # Remove duplicate tracks
)
```
#### Export to M3U
```python
# Export to M3U format (compatible with many players)
tracks = list(player.queue)
pomice.PlaylistManager.export_to_m3u(
tracks,
filepath='playlists/my_playlist.m3u',
name='My Playlist'
)
```
#### Get Playlist Info
```python
# Get metadata without loading all tracks
info = pomice.PlaylistManager.get_playlist_info('playlists/my_playlist.json')
# Returns: {'name': '...', 'track_count': 42, 'total_duration': 7200000, ...}
```
### JSON Format
```json
{
"name": "My Playlist",
"description": "Best songs",
"created_at": "2024-01-15T12:30:00",
"track_count": 10,
"total_duration": 1800000,
"version": "1.0",
"tracks": [
{
"title": "Song Title",

}
]
}
```
---
## 🔧 Track Utilities
Advanced filtering, searching, and sorting utilities for tracks.
### TrackFilter
Filter tracks by various criteria.
```python
import pomice
tracks = list(player.queue)
# Filter by duration (milliseconds)
short_tracks = pomice.TrackFilter.by_duration(
tracks,
min_duration=60000, # 1 minute
max_duration=300000 # 5 minutes
)
# Filter by author
artist_tracks = pomice.TrackFilter.by_author(
tracks,
author='Imagine Dragons',
exact=False # Case-insensitive contains
)
# Filter by title
title_tracks = pomice.TrackFilter.by_title(
tracks,
title='Thunder',
exact=True # Exact match
)
# Filter by requester
user_tracks = pomice.TrackFilter.by_requester(tracks, requester_id=123456789)
# Filter by playlist
playlist_tracks = pomice.TrackFilter.by_playlist(tracks, playlist_name='Rock Hits')
# Get only streams
streams = pomice.TrackFilter.streams_only(tracks)
# Get only non-streams
non_streams = pomice.TrackFilter.non_streams_only(tracks)
# Custom filter with lambda
long_tracks = pomice.TrackFilter.custom(
tracks,
predicate=lambda t: t.length > 600000 # > 10 minutes
)
```
### SearchHelper
Search, sort, and organize tracks.
```python
import pomice
tracks = list(player.queue)
# Search tracks
results = pomice.SearchHelper.search_tracks(
tracks,
query='imagine',
search_title=True,
search_author=True,
case_sensitive=False
)
# Sort by duration
sorted_tracks = pomice.SearchHelper.sort_by_duration(
tracks,
reverse=True # Longest first
)
# Sort by title (alphabetically)
sorted_tracks = pomice.SearchHelper.sort_by_title(tracks)
# Sort by author
sorted_tracks = pomice.SearchHelper.sort_by_author(tracks)
# Remove duplicates
unique_tracks = pomice.SearchHelper.remove_duplicates(
tracks,
by_uri=True, # Remove by URI
by_title_author=False # Or by title+author combo
)
# Group by author
grouped = pomice.SearchHelper.group_by_author(tracks)
# Returns: {'Artist Name': [track1, track2, ...], ...}
# Group by playlist
grouped = pomice.SearchHelper.group_by_playlist(tracks)
# Get random tracks
random_tracks = pomice.SearchHelper.get_random_tracks(tracks, count=5)
```
---
## 🎯 Complete Example
See `examples/advanced_features.py` for a complete bot example using all these features.
### Quick Example
```python
import pomice
from discord.ext import commands
class Music(commands.Cog):
def __init__(self, bot):
self.bot = bot
self.history = pomice.TrackHistory(max_size=100)
@commands.command()
async def stats(self, ctx):
"""Show queue statistics."""
player = ctx.voice_client
stats = pomice.QueueStats(player.queue)
summary = stats.get_summary()
await ctx.send(
f"**Queue Stats**\n"
f"Tracks: {summary['total_tracks']}\n"
f"Duration: {summary['total_duration_formatted']}\n"
f"Streams: {summary['stream_count']}"
)
@commands.command()
async def export(self, ctx):
"""Export queue to file."""
player = ctx.voice_client
pomice.PlaylistManager.export_queue(
player.queue,
'my_playlist.json',
name=f"{ctx.guild.name}'s Queue"
)
await ctx.send('✅ Queue exported!')
@commands.command()
async def filter_long(self, ctx):
"""Show tracks longer than 5 minutes."""
player = ctx.voice_client
tracks = list(player.queue)
long_tracks = pomice.TrackFilter.by_duration(
tracks,
min_duration=300000 # 5 minutes
)
await ctx.send(f'Found {len(long_tracks)} long tracks!')
```
---
## 📝 Notes
- All duration values are in **milliseconds**
- History is per-guild (you should maintain separate histories for each guild)
- Exported playlists are in JSON format by default
- M3U export is compatible with most media players
- All utilities work with standard Pomice Track objects
## 🤝 Contributing
