Examples

Basic Usage

1. Create a playlist for one music album:

   cd myalbum
   mkpl myalbum.m3u
   # or use default naming
   mkpl
   

Directory & Format Filtering

2. Create playlist from specific format:

   mkpl -d HarryPotter -f mkv HP_saga.m3u
   

3. Create shuffled playlist with size filters:

   mkpl -d "my_mp3_collection" "my_mp4_collection" -rs -z 2mb -A 4mb "my music.m3u"
   

4. Exclude specific directories:

   mkpl -d "my_mp3_collection" "my_mp4_collection" -r -s -e "my_mp3_collection/metallica" "my_mp3_collection/dk" -- "my music.m3u"
   

Advanced Filtering

5. Limit by track count:

   mkpl -d "my_series/GOT" -m 15 "got_first_15.m3u"
   

6. Filter by track number with regex:

   mkpl -d "my_mp3_collection" -r -p "^[12]|[012]{2}" "my music.m3u"
   

7. Filter by duration range:

   mkpl -d "music_collection" -M 42 -X 300 "My new collection"
   

File Management

8. Add external files to playlist:

   cd myalbum_special
   mkpl myalbum_special.m3u -F music_video.mp4 other_stuff/song1.mp3 other_stuff/song2.mp3
   

9. Add remote file links:

   mkpl -d "new_collection" -r "my music.m3u" -l http://192.168.1.123/mp3/song1.mp3 http://192.168.1.123/mp3/song2.mp4
   

10. Merge playlists:

    mkpl -d "Rock'n'Roll" -- "RockNRoll.m3u"
    mkpl -d "Hard Rock" -j "RockNRoll.m3u" -- "Rock.m3u"
    

Metadata & Formatting

11. Add playlist metadata:

    mkpl -d "new_collection" -r "my music.m3u" -t "My Collection" -g "UTF-8" -I "new_collection/cover.jpg"
    

12. Include track information (#EXTINF):

    mkpl -d "HeavyMetal/Master of Puppets" -N "master"
    cat "master.m3u"
    #EXTM3U
    #EXTINF:516,Metallica - Master of Puppets
    HeavyMetal/Master Of Puppets/02 - Master Of Puppets.mp3
    

Sorting & Organization

13. Sort by various criteria:

    mkpl -d "new_collection" -r "my music.m3u" -o        # by name
    mkpl -d "new_collection" -r "my music.m3u" -O        # by date
    mkpl -d "new_collection" -r "my music.m3u" -T        # by track
    mkpl -d "new_collection" -r "my music.m3u" -y        # by year
    mkpl -d "new_collection" -r "my music.m3u" -Z        # by size
    mkpl -d "new_collection" -r "my music.m3u" -L -D     # by length (descending)
    

14. Split into multiple playlists:

    mkpl -d "folder1" "folder2" "folder3" -r "my_music.m3u" -S
    # Results in: my_music.m3u, folder1.m3u, folder2.m3u, folder3.m3u
    

Metadata Filtering

15. Filter by artist and album:

    mkpl -d "HeavyMetal" -Y artist=Metallica -Y album="Master of Puppets" -- "MoP.m3u"
    

Interactive & Utility Operations

16. Count files:

    mkpl -d "new_collection" -r -C
    # Output: 4023
    

17. Interactive confirmation for each file:

    mkpl -d "new_collection" -r -R
    Add file new_collection/sample1.mp3 to playlist? [Y/n]: y
    

18. Append to existing playlist without duplicates:

    mkpl -d "new_collection" -rsu "my music.m3u" -a
    

Use it like Python module

You can use mkpl programmatically in your Python projects to build and write playlists dynamically.

Quick Start

Import the main functions:

from make_playlist import make_playlist, write_playlist

Basic example — create and write a playlist:

# Find multimedia files whose names start with a-f
playlist = make_playlist(
    '/Music/collections',
    ('mp3', 'mp4', 'aac'),
    pattern='^[a-f].*',
    recursive=True,
    unique=True
)

write_playlist('/Music/AtoF.m3u', 'wt', playlist)

Important Notes

• make_playlist() returns a Playlist object containing PlaylistEntry items
• You can iterate, filter, or convert results to a list before writing
• Most CLI flags are exposed as keyword arguments (e.g., recursive, unique, add_info, encoding, title, image)
• Use encoding='utf-8' parameter for UTF-8 encoded output
• pathlib.Path objects are fully supported

Python Examples

Example 1: Write UTF-8 playlist with metadata

from pathlib import Path

plist = make_playlist(
    Path('/Music/collections'),
    ('mp3',),
    recursive=True
)

write_playlist(
    Path('/Music/AtoF.m3u'),
    'wt',
    plist,
    encoding='utf-8',
    title='A–F Collection',
    image=Path('/Music/cover.jpg')
)

Example 2: Inspect and filter results

results = make_playlist(
    '/Music/collections',
    ('mp3', 'flac'),
    recursive=True
)

for entry in results:
    print(f"File: {entry.file}")
    if entry.extinf:
        print(f"Info: {entry.extinf}")

Example 3: Advanced filtering with metadata

playlist = make_playlist(
    '/Music/HeavyMetal',
    ('mp3',),
    recursive=True,
    filters=[
        ('artist', 'Metallica'),
        ('album', 'Master of Puppets')
    ],
    add_info=True
)

write_playlist('/Music/MoP.m3u', 'wt', playlist)
