DESCRIPTION
This manual page documents briefly the simadb_cli commands.
simadb_cli is a command line interface to get and edit users similarities and blacklist database used
with MPD_sima. The default database file (see the section called “FILES”) can be overridden if you want.
Consider reading the section called “A WORD ABOUT SIMA DATA BASE” to understand the structure and
relation of similarities within the database.
EXAMPLE
Similarity edition
Here follows some simple examples on how to deal with similarity database.
Pay attention, the following examples set one-way similarities in the DB! Read more about it in the
section called “A WORD ABOUT SIMA DATA BASE”.
Adding a similarity between two artists. In the following example "Pelican" will point to "Russian
Circles" with a match score of 88% (ie. "Russian Circles" 88% similar to Pelican, not reciprocal), it
will also check against MPD the presence of both artists in the music library.
simadb_cli --add "Pelican,Russian Circles:80" --check_names
Similarity string use comma "," as artists separator and semi colon ":" for artist/similarity score
separator, cf. the section called “SIMILARITY FORMAT”.
Adding a similarity between multiple artists. In the following example "Rage Against The Machine" will
point to "Tool" and "Audioslave" as similar artists and controls artists names are actually in MPD music
library.
simadb_cli --add "Rage Against The Machine,Tool:70,Audiosalve:80" --check_names
Viewing similarit(y|ies) for an artist. In the following example we are looking for entries for "Rage
Against The Machine"
simadb_cli --view_artist "Rage Against The Machine"
Black list edition
Adding to black list. You can add a single track, an album or an artist to the black list. The element
to black list is chosen from the currently playing track. Use --bl_curr_trk to prevent simadb_cli to
queue this track, --bl_curr_alb or --bl_curr_art respectively for the album and the artist.
Remember you need access to your MPD server to retrieve information to black list. Defaults are
localhost:6600 or found in environment variables but you may set it up from command line:
simadb_cli --bl_curr_art -S mympd.example.org
To black list a specific artist (not currently playing) you can use --bl_ar="Artist name to black list".
OPTIONS
The program follows the usual GNU command line syntax, with long options starting with two dashes ("-").
A summary of options is included below.
-h, --help
Print help and exit.
--version
Print version and exit.
-a similarity_string, --add_similarity=similarity_string
Add similarity to the database.
For more details about the similarity_string see the section called “SIMILARITY FORMAT”.
-c, --check_names
Use with --add_similarity in order to check artists names used in similarity_string. simadb_cli will
control presence of artists names in MPD library. Default is to look for MPD server on localhost:6600
or environment variables MPD_HOST and MPD_PORT if set.
You can as well give simadb_cli host/port on the command line using respectively -S and -P.
--bl_art=artist_name
Use to black list artist_name. simadb_cli is checking artist_name is actually in MPD music library
(cf -S and -P options to set MPD host/address if necessary).
If artist_name is not found the script print out a list of matching artists.
--bl_curr_trk | --bl_curr_art | --bl_curr_alb
Use to black list the currently playing track|artist|album. You need access to your MPD server, use
-S and -P to set MPD host/address if necessary.
-d db_file, --dbfile=db_file
Use the specific file db_file as database.
Default is too use XDG_DATA_HOME (see the section called “FILES”).
--purge_hist
Purge history, you may supply an alternative DB file with --dbfile option.
-r, --reciprocal
Use with an editing options in order to edit reciprocal similarity as well. --add_similarity and
--remove_{artist|similarity} are supporting reciprocal edition.
N.B: this option has to appear after the editing option on the command line.
See the section called “A WORD ABOUT SIMA DATA BASE” for further information about reciprocity
notion.
--remove_artist=artist
Use to remove an artist entry (as main artist) with its associated similarities. To remove artist
where it appears as a similar artist use the --reciprocal option.
--remove_bl=row_id
Use to remove a black list entry. To get the row_id to suppress use --view_bl option.
--remove_similarity="main artist,similar artist"
Use to remove a single similarity between a main artist and an associated similarity. Give the main
artist first, use comma (",") to separate it from similar artist.
Use of --reciprocal is possible here, see the section called “A WORD ABOUT SIMA DATA BASE”.
This option is useful in case you want to remove only a specific similarity between two artists, to
remove completely an artist use --remove_artist instead.
-v "artist name", --view_artist="artist name"
Get entries for "artist name" in the data base (print to stdout).
--view_bl
Get all entries in the black list.
--view_all
Get all entries in the data base (print to stdout).
-P mpd_port, --port=mpd_port
Use the specific port number mpd_port on MPD server. This overrides MPD_PORT environment variable.
Default is 6600.
-S mpd_host, --host=mpd_host
Use the specific host mpd_host as MPD server.
mpd_host can be an IP or a fully qualified domain name as long as your system can resolve it. This
overrides MPD_HOST environment variable.
Default is localhost.
FILES
${XDG_DATA_HOME}/mpd_sima/sima.db
SQLite DB file. Usually XDG_DATA_HOME is set to ${HOME}/.local/share.
SIMILARITY FORMAT
The similarity_string has to be formatted following a special pattern in order for simadb_cli to extract
similarity relations between artists names. Usually a similarity entry is defined as a main artist, lets
say main_art, followed by a list of similar artists which you want to be related to that main_art, each
artist of that list with a specific similarity value, a match score, quantifying the similarity relation
with the main_art. The match score value is an integer in [0 ,100] with 100 corresponding to a perfect
match.
similarity_string is then to be formatted as follow:
main_art,first artist:<score>,second artist:<score>
Each artist group are separated with commas (",") and inside each group the artist name and the match
score is colon (":") separated. Obviously the first artist group, as the main artist, does not have a
match score.
Lets see how it works with an example. I consider "Led Zeppelin" to be similar to "Tool" with a match
score of 25, I also want to have "Audioslave" related to "Led Zeppelin" with a score of 20. Then the
similarity_string will be the following:
Led Zeppelin,Tool:25,Audiosalve:20
See the section called “A WORD ABOUT SIMA DATA BASE” for more details about how similarities are handled
A WORD ABOUT SIMA DATA BASE
The similarity database is defined from the point of view of a main artist which is declared related to a
list of similar artists. That means when you define main_art to be similar to sim_art A and sim_art B the
reciprocal won't be true, sim_art A and sim_art B are not similar to main_art. At least this is the
default behavior when you edit entries with simadb_cli, this is also the way last.fm is working
concerning similar artists. This documentation is using that particular terminology to specify which kind
of artist we are dealing with : "main artist" or "similar artist".
The --reciprocal option allows one to add reciprocal relation where sim_art A and sim_art B become
respectively the main_art. Using --reciprocal you will then edit two more entries in the database. To
summarize here is what you'll end up with in your data base adding similarity with this string
main_art,sim_art A:34,sim_art B:45.
simadb_cli --reciprocal --add_similarity=main_art,sim_art A:34,sim_art B:45
main_art similar to sim_art A:34 and sim_art B:45
sim_art A similar to main_art:34
sim_art B similar to main_art:45
Without the reciprocal option you would have add only the first similarity. Usually using the reciprocal
option is the desired behavior, at least what users have in mind when thinking of similarity relation
between to artists but keep in mind that it may lead to have MPD_sima more sensible to loop over the same
two artist (ASSERTION TO BE CONFIRMED).
