Re: goals vs requirements

Hi,

Again I had some answers that I want to comment:

Ed is giving some good cases for modularity.  I just want to point one 
thing out: minimal interface.
Having a small (but complete) interface is the corner-stone of a modular 
development.
This is currently not the case. The PlaylistManager alone has around 30 
functions, sends four events and has it's fingers all over the place.
I tried to change this and belive me it is extremly hard.
Please try this too so that you can see for yourself why I wanted a 
structured development process.
This is not about re-writing the code. This is about finding out what 
needs to be fixed.


Kristian is writing about two different points.
First about the metadata issue. Kristian, I am totally agains saving 
meta-data in a playlist item. As we found out (via the requirements) we 
only need to determine the meta-data in very special cases.
Again I encourag you to write a working design in the requirements 
document, a simple text file or in comments. Please feel free to change 
what you like, but GOD DAMN DO IT. I can't understand the current design 
and every sentence you are writing is confusing me more.
What exactly does the music-catalog do? Please write it down or you will 
be the only person that can write code for this.

Another point is the work-split between player and playlist.

current: getNextSong getPreviousSong  -- player-playlist
setShuffle getShuffle setRepeat getRepeat -- player-ui
getPlaylist getCurrentSong setCurrentSong -- ui-playlist

proposed
getPlaylist -- player-playlist
setShuffle getShuffle setRepeat getRepeat getPlaylist getCurrentSong 
setCurrentSong -- player-ui

As you can see at least two functions are missing. I could bet that 
there are other improvements, but one argument top's it all.
The playlist is now more understandable because it only manages the list 
and nothing more.


BR,
Ralf
