Feature Request (play random Song / follow playback in view)

Hi everyone,

I recently discovered this great Music Player, however I'm missing two  
small Details. Having used foobar2000 before, I'd love to have a command  
that plays a random Song from the current view (would be great if usable  
via cmus-remote, too). In conjunction to that, it'd be great if there were  
a "Cursor follows Playback" equivalent. Simply an option to append  
"win-sel-cur" to every track change would be awesome. If something like  
this is already possible, I'd be glad if you give me a small hint in how  
to get it working.

Greetings

Jiaom

Thanks for your suggestions and great you like cmus!

There is the "tqueue" command to queue a random song from the library.
As far as I know, there is no way to get the current view via
cmus-remote, so there is no possibility to script this behaviour.

Are there any objections to output the current view via
`cmus-remote -Q`? Then a script would be possible!

This has been requested multiple times in the past. I wrote a small
shell script which accomplishes that:

Can you check if it works? You have to set it as status_display_program:

the one thing i've been wondering several time: is there a way to 
randomize the current queue (or pick a random song from the queue)?

my use case is:
- i add several albums (or songs sorted by authour) to the queue
- and then i won't to listen to all those songs in a random order

ciao

Hmm, I don't think randomizing the queue is possible at the moment. But
why not use the playlist instead? If you want to use the queue, I wrote
a script that pushes tracks/albums to the queue in a random order:
http://cmus.sourceforge.net/wiki/doku.php?id=cmus_queue_randomly

You can bind it to a key:
:bind -f common ^E run cmus_queue_randomly

Does this solve your problem?

I was wrong, I wrote a (bit hacky) script that does select the next
track in the current view (view 1-3):
http://cmus.sourceforge.net/wiki/doku.php?id=cmus_play_random

Is this what you meant?

Just wanted to clarify that I uploaded all scripts in this thread while
writing the mails (had them / or similar scripts locally). Otherwise it
looks like I would suggest that people didn't RTFM... sorry for that!
