A simple command-line media indexer and jukebox.

optional arguments:
  -h, --help            show this help message and exit
  -l LOCATION, --location LOCATION
                        the location to search for media files [~/Music]
  -q QUERY, --query QUERY
                        input an SMJ7-style query, followed by playlist
                        commands, and disable interactive mode (see --syntax)
  --database DATABASE   the location to store the media database
                        [~/.smj/smj7.sqlite]
  --freshen             search for new files and scan them, and update
                        existing entries in the database, useful when adding
                        new albums or changing metadata
  --prune               delete entries from the database if the file no longer
                        exists (Note: if you suspect a large amount of files,
                        use --force-rescan instead)
  --force-rescan        nuke the database and start from scratch, useful when
                        a lot has changed since the last scan
  --json                skip playback and interactive selection, just output
                        matching results in JSON
  --show-paths          include path information in JSON track output
  -i INDENT, --indent INDENT
                        with --json, # of spaces to indent by, set to 0 to
                        dump block of text [2]
  --force-serial        disable parallelized media parsing, useful for slower
                        machines or older mechanical hard disk drives
  --syntax              show SMJ7-sylte syntax guide
  -d, --debug           enable debug mode

SMJ7-Style Syntax

tl;dr

Enjoy quick shorthand and get to your music quickly, easily, and all from the command line:

• ./smj7.py -q '@awol, #run' : Automatically play all songs off of "Run" by "AWOLNATION"
• ./smj7.py -q '@decem, #live, $infanta' : Play the live version of "Infanta" by "The Decemberists"
• ./smj7.py -q '!electronic, !dance, !party; s' : Play a shuffled mix of those 3 genres

SMJ7 supports a new syntax for chaining queries together using single-character notation. You can combine multiple parameters; like-type parameters will be logically ORed and unlike-type parameters will be logically ANDed together.

• !some string - Search for genres matching the string
• @some string - Search for artists matching the string
• #some string - Search for albums matching the string
• $some string - Search for tracks matching the string
• some string - Search for artists, albums, or tracks matching the string

Combinations

Parameters are comma-separated, and combined logically as mentioned above. All strings are searched case-insensitively and will match on partial hits.

• @artist1, @artist2 - Would search for any songs by either artist1 or artist2
• @artist1, #album1 - Would search for any albums with "albums1" in it by any artist with "artist1" in it.
• something1 - Would search for anything matching "something1", in any field
• something1, $track1 - Would search for any tracks matching "track1" that have "something1" related to them

Common Uses

• term1, term2, term3 - Keep searching everything until the additional terms yield the specificity you wish
• @artist1, @artist2, #greatest hits - Play the "Greatest Hits" albums by both artist1 and artist2
• @artist, #album, $tracknumber - Play a specific track off of a specific album, useful when live albums exist alongside

Examples

• @mingus, @coltrane, @brubeck - Would play some assorted jazz tracks by these 3 artists
• @rolling stones, #greatest - Would match "Greatest Hits" by "The Rolling Stones"
• @decemberists, #live, $infanta - Would play the live version of "Infanta" by "The Decemberists"

Playlist post-commands

When invoking from the command line, you should encapsulate your SMJ7-style query in quotes, so that your shell can pass it here properly.

To add playlist commands, simply append a semicolon ";" to your query and follow it with one of:

• - Play the #th song

• a - Play all matching songs
• r - Play a single, random matching song
• s - Play all matching songs, shuffled

Examples of SMJ7-style query plus commands:

• ./smj7.py -q "@rolling stones, #greatest; a" - Plays all songs matching the query
• ./smj7.py -q "@decemberists, #live; s" - Plays all songs matching the query, in a random order
