Hack 91. Discovering Your Favorite Actors
Hack 91 Discovering Your Favorite Actors
Ever think about who your favorite stars of the small screen are? I don't mean those you can think of off the top of your head. I mean based on actual television viewing habits .
We already have a framework to key off and siphon data from the television shows in the Now Playing List [Hack #90]. Now, let's gather some slightly different data. We'll make an account of all the actors and actresses in the television shows we watch, perhaps spotting trends in those we tend to gravitate toward.
Programmatically, this isn't any more than grabbing the Actor rather than the Title and EpisodeTitle attributes from the Program object. The Actor object lists all the stars of a particular show, which we'll parse to draw out the individual names and tally up the number of times they show up in your Now Playing List .
The Code
#!/tvbin/tivosh # open the database, and for each television show, # extract the date it aired, the title of the show, # and the episode title set db [dbopen] # pull out the first 50 recorded shows from the database set recdir "/Recording/NowShowingByTitle " RetryTransaction { set files [mfs scan $recdir -count 50] } set actors { } while { [llength $files] > 0 } { # iterate through the shows we extracted foreach rec $files { # grab the FSID of the program from the list set fsid [lindex $rec 0] RetryTransaction { # get the object that represents this recording and the # object that represents this episode. wrap it in a # catch just in case it doesn't work set recordingobj [db $db openid $fsid] set episodeobj [dbobj [dbobj $recordingobj get Showing] get Program] # pull out the list of actors in this show set epactors [dbobj $episodeobj get Actor] } # transform the actors names into strings and append them to # our list of all the actors on our TiVo foreach epactor $epactors { set slashpos [string first "" $epactor] set repactor \ " [string range $epactor 0 [expr $slashpos - 1]] ," set repactor \ " $repactor [string range $epactor [expr $slashpos + 1] end] " lappend actors $repactor } } # and grab the next 49 television shows set lastName [lindex [lindex $files end] 1] RetryTransaction { set files [mfs scan $recdir -start $lastName -count 50] } if { $lastName == [lindex [lindex $files 0] 1] } { set files [lrange $files 1 end] } } # create a new list called factors that is the frequency count of the # actors on the shows we have watched set factors { } foreach l $actors { if ![ info exists a($l) ] { set a($l) 0 } incr a($l) } foreach i [ array names a ] { lappend factors [list $i $a($i)] } # and let's quickly alphabetically sort then print the list [RETURN] set factors [lsort -index 0 $factors] foreach factor $factors { puts "[lindex $factor 0] [lindex $factor 1] " }
Save the code to a file called actors.tcl in TiVo's /var/hack/bin directory and make it executable:
bash-2.02# chmod 755 /var/hack/bin/actors.tcl
Running the Hack
Run the script from TiVo's command line Section 3.3:
bash-2.02# /var/hack/bin/actors.tcl Ackles, Jensen 4 Agena, Keiko 2 Berkeley, Xander 1 Bernard, Carlos 1 Bishop, Kelly 2 Bledel, Alexis 2 Brook, Jayne 1 Burton, LeVar 1 Carradine, Ever 1 Channing, Stockard 4 Corbett, John 1 Cuthbert, Elisha 1 Dorn, Michael 1 Esposito, Giancarlo 1 Forsythe, William 1 Frakes, Jonathan 1 Gardell, Billy 1 Glover, John 4 Graham, Lauren 2 Gunn, Sean 2 Haysbert, Dennis 1 Herrmann, Edward 2 Hill, Dule 4 Holmes, Katie 15 Hudson, Oliver 5 Humes, Mary-Margaret 1 Jackson, Joshua 15 Janney, Allison 4 Jerald, Penny Johnson 1 Jones III, Sam 4 Jones, John Marshall 1 Kajlich, Bianca 5 Kreuk, Kristin 4 Lowe, Rob 4 Mack, Allison 4 Malina, Josh 1 McCarthy, Melissa 2 McFadden, Gates 1 Moloney, Janel 4 ...
To capture your list of favorite actors as a pipe-delimited text file, use the > redirect symbol and supply the name of a file to which to write. For example, sending output to a file called actors.out in the /var/out directory would look like this:
bash-2.02# /var/hack/bin/actors.tcl > /var/out/actors.out
