So far, we have three entries, all with distinct solutions. Only 3 days left to enter...

Well, count me out. Didn't get to it. Next time!

Okay, here are the results, sorted by order of submission, path-coded for Windows XP:

Kudos to Thicket for the shortest code!
Honorable mention to TIG for second-shortest by 4 characters.
Kudos to Jim for checking the filesize to get the delay time!
Kudos to TIG for a really clever way of presenting the track info and avoiding both sound overlaps and system sound intrusion!

Now, for the follow-up challenge:
Create the jukebox with less than 100 characters! Entries due by noon (GMT-6) on Monday, 6 August 2007. Short challenge, but the hard work's been done

Here's mine:

iTunes

What do I win?

RickW

Good effort, but you didn't use the UI.play_sound(filename) method.

I'm also a bit worried if you put your system sounds into iTunes

Jim

I was curious about the behavior of UI.play_sound. On my system, window 2000 pro, I wrote the core of the challenge as follows:


Dir["c;\winnt\media\*"].each {|s| UI.play_sound(s)}

This played all the sounds simultaneously. Is the behavior the same for everyone?

RickW

That's what I got...

RickW

Okay, round 2 is closed. TIG and I each got it down to 84 characters with the following code:

@tig said:

c=0;Dir["C:/WINDOWS/Media/*v"].each{|w|UI.play_sound w;UI.inputbox([w],["#{c+=1}"])}

@rickw said:

i=0;Dir["C:/WINDOWS/Media/*v"].each{|f|UI.play_sound f;puts"#{i+=1}: #{f}";sleep(3)}

I could have squeezed it to 83 by removing the space after the : in the puts statement, but decided against it.

Thanks to everyone who worked on this - it was a fun challenge, and we should do another one next month

RickW

Too late for deadline, but a shorter (77 characters) solution:

i=0;Dir["C:/WINDOWS/Media/*"].each{|f|UI.play_sound f;puts [i+=1,f];sleep(3)}

If anyone can reduce it from here, please post and enlighten us all

OBFUSCATORS! You should be trying to make it MORE readable, not less! (switch to high, crackly voice) You young punks don't know how good you've got it! Why, back in my day, all we had was ones and zeros. And sometimes we didn't even have zeros, and we had to use the letter O!

i=0;Dir["/WINDOWS/Media/*"].map{|f|UI.play_sound f;p i+=1,f;sleep 3}

That would be 68?

RickW

Nice job Jim!

Clark, that was too funny

TIG

Tweaking Jim's..

i=0;Dir["/*/Media/*v"].map{|f|UI.play_sound f;p i+=1,f;sleep 3}

That would be 63... AND it only plays wav files, not falling over on midi's etc... (62 otherwise)

Alright TIG!

A note about using Dir[""]: I didn't specify a file ending because I have files that end in .WAV. These files do not get played because they end in capital letters. The shortest way to get ALL the files was o use *.

RickW

hmm... the last two solutions won't play on my machine.

Both work for me.

rombout

interesting this stuff does anyone know how to stop a file from playing in UI

morisdov

rombout look here - stopping UI.play_sound ? -

yeah i already knew that one. But thanx anyway, did you already found different solution
