mprand is a special-purpose mpd client to random-play from the entire mpd database (currently only with uniform distribution). It improves upon one other implementation of this concept of which I'm aware (Josh Kunz' ashuffle - https://github.com/Joshkunz/ashuffle) in one major respect: it does not rely on the deprecated 'listallinfo' mpd request (which can quickly become prohibitively expensive with large databases over the network). It also ensures that there are always at least two songs in the queue, so that playback is continuous (mpd's gapless playback can function, and the built-in http streaming server will not go down between songs); this also serves as a primitive yet elegant "up next" feature. (ashuffle can do this, but does not behave this way by default.) tkmprand expands on this concept by providing a GUI client for perpetual random play, providing a status and up-next display and minimal transport controls, automatically appending random songs to the queue so it never runs out. The code mprand and tkmprand use to talk to MPD is factored into a package named mpd_proto; this may prove useful as the nucleus of an MPD client library for some other purpose. Expanding mpd_proto into a full MPD client library for Tcl is a long-term goal. USAGE At the moment these scripts accept no options. mprand will, when executed, begin random-playing on localhost:6600 (or the host and port specified by MPD_HOST and MPD_PORT, if these environment variables are set). Random play continues until another client stops playback, at which point mprand will terminate. Note that the mpd_proto/ directory must be located somewhere in Tcl's package search path; the easiest way to accomplish this is to set TCLLIBPATH="." or something to that effect in the environment. Both scripts also require simulation::random from tcllib, and tkmprand won't be able to display JPEG cover art without Img (packaged as libtk-img on Debian and derivatives). CAVEATS Neither client supports connecting to MPD with a UNIX domain socket, since (to my knowledge) the Tcl core doesn't support UNIX domain sockets. SEE ALSO ashuffle <https://github.com/Joshkunz/ashuffle> - Another special-purpose random- play client as mentioned above. mpd-sima <https://github.com/mxjeff/mpd-sima> - A general-purpose autoqueue client with numerous possible queueing policies, including random behavior similar to mprand and tkmprand.
