Subject: RE: search a string
From: John Wood (John.Wood_at_royalblue.com)

>> If I understand correctly, that was what François was trying at first.
But it was too slow. <<

I wrote a prototype that searches the current playlist for a string -- a
playlist of 2000 songs. It took about 3 seconds on the recorder, is that
really too slow?

It did load most of the playlist in mind you -- used malloc (which is why I
haven't submitted it, I needed to change it to use static mem which would be
slower and generally a waste of space if you ask me... using static memory
for everything is a bad idea if you ask me, put me off developing for
rockbox).

My prototype had 2 options -- one for doing a scan of the whole hard disk
(which would take about 10 seconds and would thrash the disk), and another
that scanned the playlist. Having a third option to use an index file would
be even better. But I think you should give all options in case the index
file isn't up to date.

John
