It’s been a busy few weeks for PandoraBoy… well, for PandoraBoy’s mailbox. I’ve been incredibly busy getting my day-to-day work out for months now and have barely looked at PandoraBoy since about February. The backlog of Issues has grown to a troubling level, and it’s probably another few weeks before I’ll be able to get back into PB development. But in the meantime I’ve been amazed at how much mail I’ve been getting on the subject. Mostly small bugs people are running into, but then, this just in:
PandoraBoy in French. Yes, Pierre Rudloff, out of the blue, sends me a fully translated lproj. I really appreciate it. I’ll make sure to get it integrated into the next release. I probably won’t get started on PB development until after WWDC because of other projects, but after WWDC it’s top of my list. Especially all the annoying little bugs that have been creeping in (I suspect because of some backend Pandora changes).
To all you aspiring Cocoa developers….
If you want to make a private framework, you need to remember to set the install path for it to @executable_path/../Frameworks. Just copying it into your bundle isn’t good enough. Otherwise your app is going to think it’s in (~)/Library/Frameworks once you package it up and give it to other people.
In related news, PandoraBoy 0.5.1a is now released.
Yes it is true, a new version of PandoraBoy is up, 0.5.1. I haven’t put it into Sparkle yet, and probably will skip it because it only fixes a couple of things (most notably, paid accounts now work correctly). Technically there’s an entire full-screen mode in there now with a plug-in architecture and public framework, but I’ve disabled it because it’s still kind of flakey and doesn’t work very well. I’m going to focus for a while instead on some of the bugs that have been reported and get those cleaned up.
Maybe I’ll play with the new version of ShortcutRecorder that just came out thanks to OmniGroup’s contributions (great company, great products). Hopefully I can get rid of my IB2 dependencies and finally move 100% into XCode3.
And of course I’ve been promising improvements in Sparkle that will help PandoraBoy a little bit, and I more deeply need for my day job. I’ve been mostly working on those during what I consider “day job” hours, but right now core product features are far more pressing than automatic updates. And #1 on my list: collapse the current branch back down to trunk! Ah, subversion, thou viper. Linus was right. There’s no such thing as “CVS done right.” But in truth, it isn’t so terrible, it just isn’t so good either….
I haven’t forgotten about PandoraBoy, but I’ve been very busy these last couple of weeks. I’m now a full-time Mac programmer, and so I’ve been spending most of my time doing “real” hacking. Next week I go to Big Nerd Ranch for training, so I’ll take PB with me to hack on.
I just built my first kernel extension and begun trying it out. Kernel programming is a whole different world… When it doesn’t work, Gray Screen/Reboot. I’m glad that (a) OSX boots quick, and (b) I have a lot of computers…
I’m trying to waste system resources in a guaranteed way. I have these boxes with 2G of memory, and need to test problems that show up on 512MB machines and I don’t have any 512MB sticks….
As I study Mac OS X Advanced Programming, I think I may be able to do this with mlock() and not have to use a kext. I’ve read other things that suggest that mlock() won’t work the way I want in a user app. So testing is in my future.
Full-screen PandoraBoy has been a major learning experience. Quartz Composer is an incredible tool, but it took me a long time to get rid of the random noise in the picture. First secret: spend some time and read through every patch available, particularly the ones in Tools. It’s important to know what’s available so you don’t spend hours trying to reinvent the basics. And don’t forget that “transparent” defaults to meaning “whatever random memory happens to be on the video card.”
I’ll be spend quite a bit of time trying to improve the interface for the full-screen plugins. I’m trying to make it as easy to write new full-screen modes as to write new screen savers. Once I’ve gotten a second full-screen plugin written, I think I’ll better know how to structure the interface.
I’ve also finally gotten rid of an old, nagging bug where PB would fail to respond to keyboard shortcuts or Applescript. WebKit is a bit funny about plugins (i.e. Flash). I finally tracked down a weird race condition that causes hitTest: to sometimes return the Flash view and sometimes to return the view that contains the Flash view. PB was only handling the more common case, so sometimes you’d get a stray “ERROR: Could not find webNetscapePluggin” error in your logs. Hopefully that’s now fixed.
Huge changes in PandoraBoy on the way. I’m working on full-screen mode, so you can run PandoraBoy from across the room and still see what’s currently playing. Building a smooth transition from window to full-screen without interrupting playback has taken my a couple of days, but I think it’s a pleasing effect. Right now it doesn’t do a lot more than be a full-screen Pandora window (which isn’t very exciting in itself, though much harder than it sounds), but next I’ll work on a plug-in architecture to let you put various information on the bottom portion of the screen. Then it’ll actually be useful.
Why is it so hard to go full-screen you may ask? Afterall, it’s just a webpage. But the mini-player is a web page that assumes the window is a specific size. Getting the background gradient to look right at any size is the main problem, since there is no direct way to scale a background in CSS2. repeat-x handles left-to-right scaling, but the pandora background isn’t tileable vertically. My final solution was to build an NSImageView which holds a flipped version of the Pandora background, and then placed it immediately underneath the pandora webview. It handles all vertical stretching and gives a nice darker area at the bottom rather than just fading to white.
I’ll also investigate a black-screen mode with the pandora player standing with no background. I had that working at one point, but it’s been hard to recreate it in a way to zooms cleanly. CSS2 and Javascript just aren’t nearly as powerful as Cocoa….
If you’re feeling insanely adventurous, it’s all checked in on truck in subversion….
PandoraBoy 0.5 is live. Go forth.
I may not get to work on PB for a few days at least. One-way call paths will be my life for a little while I suspect. Or maybe it’s just USB audio input failing in some strange way… ah telephony.
