Theocacao: More Than Anything, Leopard is Wish Fulfillment

More Than Anything, Leopard is Wish Fulfillment

Mainstream media (understandably) likes high-visibility features which fit into quick, quotable sound bites. Four-minute TV segments and short newspaper columns are trying to catch someone on their way to work, so the features they choose may not represent the day-to-day experience. Leopard's headline features are Time Machine, Spaces, Cover Flow, QuickLook and iChat. This list alone sells Leopard short, though. I think Leopard is all about wish fulfillment.

Brand-new features make good press and incite an initial purchasing rush, but Leopard takes a different route. It takes a big bundle of things that are common requests, obvious needs, and things that people are likely to want in the future, and runs down the list, checking them all off. It doesn't make for such easy sound bites, and you can't see it from screenshots alone, but the experience in Leopard is one of discovering endless improvements everywhere.

Every single component — framework, application, tool, background process — got a crack at making drastic cosmetic and/or infrastructural improvements. Many of the applications and tools have been completely revamped. Preview, for example, is miles ahead of its predecessor. There are countless overhauls in Mail, iChat, Photo Booth, iCal, Terminal, and so on.

I know it sounds like hyperbole, but it's really true. Ask anyone who's been using for the last few months. There's no one single world-changing feature from a user perspective, but going back to Tiger really feels thin by comparison. DVD Player and Front Row are obvious examples of apps that didn't make the keynote, but bear little resemblance to their Tiger counterparts.

The net result is that the minute-to-minute experience is vastly refined. It's not nearly as flashy, but the long-term advantage of solid, practical improvements will be paying dividends long after the initial Leopard press is ancient history. I think this is a big reason we're seeing so many "favorite feature" lists — there's one no single thing. It depends on how you use your computer.

On the Other Hand

Now that's from the user perspective. Developers, on the other hand, have nothing short of a revolution in store. There are some obvious changes: Objective-C 2.0, Core Animation, a complete overhaul of Interface Builder, Xray. But that's just a glimpse. The standard for the state of the art in Leopard is miles from the equivalent in Tiger.

There are even some things in Objective 2.0 we haven't been able to talk about until today. The 64-bit runtime, for example, throws out all the old cruft and starts with a clean slate. That means you can synthesize instance variables, for example.

So we're going to have a lot to chew on. I think we've reached the point where the pull between expanding capabilities and expanding imagination has swung back in the direction of capabilities for a while.

And we haven't even talked about Leopard Server.

One More Thing

I initially saw QuickLook as a nice side-story feature that I probably wouldn't use. Why not just open the app?

I have completely changed my perspective on this. It's incredibly satisfying to select a file in the Finder and just hit the spacebar to view it without having to switch contexts into Preview, QuickTime Player, etc., particularly when you're looking for a particular image.

The best thing about this feature may be the fact that it tracks the current selection. So you can hit the space bar once, and use the arrow keys to navigate to other files when the QuickLook window updates. You can even go full-screen by clicking the double-arrow icon. I'm sold.

I was wondering when you will begin to go over some of the developer features of Leopard that have been under NDA since WWDC? Can you talk about them now? Can you give us a taste of what to expect over the coming weeks in terms of coverage and the impact these changes will have for Leopard only apps?

Thanks,
Caleb

I second Caleb's questions. I'm waiting eagerly for ObjC 2.0 tutorials to surface, as well as the first books to come out on the subject. I'm new to Cocoa and while I've dipped into it a bit already, I've been waiting for Leopard before diving in since I know the tools are changing so dramatically.

Joe Ranieri — Oct 26, 07 4843

Small gripe: it's no longer known as Xray. It's now called Instruments.

Robert McGovern — Oct 26, 07 4844

One thing I don't like about Quick Look is that once active, pressing up and down moves back and forth between items rather than scrolling (would be useful if looking at a PDF or html page, rather than having to swap back to mouse).

Otherwise it seems to be very useful and a welcome addition!

Every new Apple OS we always have the same discussion about Evolution vs Revolution. Me personally I'm not interested in someone constantly marketing "Revolutions" to me. I need solid and consistent evolution and that's what OS X has been part and parcel since coming to fruition 6 years ago.

I'm enjoying the mini reviews that I'm reading. Stability looks good and once macophiles are actually using the OS they are indeed finding the many touches of polish that are key in Apple applications. Now the fun begins.

Chris Ryland — Oct 26, 07 4847

Amen, brother!

But the odd thing is that just one or two seeds ago, things were looking pretty grim in terms of general stability and polish, and we certainly weren't seeing all the features. I wonder why the big leap at the end? Does that mean Apple was holding back on releasing a lot of the fixes and improvements until GM? Doesn't that seem odd?

Maybe I'm hallucinating, but other, well-known devs were privately saying similar things.

@Caleb: I was wondering when you will begin to go over some of the developer features of Leopard that have been under NDA since WWDC?

Starting this weekend. I have one little project in particular nearing completion.

@Robert McGovern: One thing I don't like about Quick Look is that once active, pressing up and down moves back and forth between items rather than scrolling

Page Up/Page Down works. Arrows also work in full-screen mode.

There are two new articles on developer.apple.com that talk about some of the new developer goodies.

Core Animation + Image Kit

and Objective C 2.0

I am still skeptical as to if ODF will be a supported UTI allowing average apps to write to odf and be compatible with OO.o and Koffice. Please tell us. I hold my doubt because iWork doesn't advertise the ability to write to odf.

(this part you might remove) I will be happy if text edit does i just feel that it's cheap to allow text edit to write to odf and not Pages just because Pages will be runnable on tiger.

Jens — Oct 27, 07 4852

@Chris Ryland: No conspiracy theories needed :) It always happens that way � a lot of things are in shambles until the last big push at the end that somehow miraculously cleans everything up. I've been involved in every release of OS X since 10.0, and they've all had the same trajectory.

@Scott: Oy, does that Quick Look screenshot mean that you not only have a beta of Delicious Library 2, but you've also somehow gotten your hands on Super Mario Galaxy three weeks before its US ship date?!

Blain — Oct 27, 07 4853

D'oh! I was ready to go to the Apple store until it slipped my mind at the last moment. Just as well, it'd be torture. I don't think I'm getting Leopard for a while because of two things:

1) I'm outdated. Both my powerbook shuffle and the blue and white G4 would get rejected by the installer. Maybe when the Leopard version of XPostFacto makes the installer recognize the upgrade card.

2) Is it true that there's no classic, even for the PPC macs? I'm guessing having classic in 10.4 won't run in 10.5? I mean, I understand the reasons and such, but, I needs me my Resedit.

Scott Stevenson — Oct 27, 07 4854

@Blain: Is it true that there's no classic, even for the PPC macs?
No Classic.

I understand the reasons and such, but, I needs me my Resedit
Okay, I gotta know why.

Simon Robins — Oct 27, 07 4855

On thing I find odd about the new Objective-C 2.0 properties is the duplication of effort. For example on the Objective-C 2.0 Overview page is the following code.


@interface Person : NSObject {
    NSString *location;
}
@property NSString *location;
@end

Why is NSString *location written twice?
Why isn't the property written as: @property location?

The implementation doesn't need to mention the property type.


@implementation Person
@synthesize location;
@end

Robert McGovern — Oct 27, 07 4856

@Scott Stevenson Ahh, which on my MacBook is Fn+Page Down. Not quite instinctual but at least its there. Thanks.

Chris Ryland — Oct 27, 07 4857

@Jens: K, thanks. Didn't remember quite the same situation with Tiger, but maybe I wasn't pay as much attention then.

Scott Stevenson — Oct 27, 07 4865

@Simon Robins: Why is NSString *location written twice?
Why isn't the property written as: @property location?

A property doesn't necessarily have to be backed by an instance variable with the same name, or an instance variable at all.

@interface Person : NSObject {
    NSString *realLocation;
    NSString *fakeLocation;
}
@property NSString *location1;
@property NSString *location2;
@end

@implementation Person

@synthesize location1=realLocation;
@synthesize location2=fakeLocation;

@end

Here, both properties are declared as NSString. By default, the property uses an instance variable of the same name, but you can override it with the equals sign. The @sythesize directive reads the information from the @property directive to determine the type is NSString.

Blain — Oct 27, 07 4866

Okay, I gotta know why.

Honestly, I don't really, save for sentimentality for the Jack-in-the-Mac. I've even booted into OS9 a few times for the sake of Disinfectant's Pythonesque About dialog. Ah, those were the days. Although, for a while, I couldn't find a better pixel pusher than the icl8 editor.An emulator's been mentioned elsewhere, so it's all moot.

Most likely, I'll either make the jump when I can get it on the B&W or simply upgrade to an intel mac when I can budget it, passing up the G5 altogether.

This is all explained in the documentation -- see for example
Cocoa > Objective-C Language > The Objective-C 2.0 Programming Language > Properties > Property Declaration and Implementation.

Quick Look is great, but there should be a keyboard shortcut for full-screen mode. It's really inconvenient to mouse for the full-screen arrows. (Maybe this has to do with Steve's aversion to the keyboard? If so, I'm getting worried. I hope he gets over it soon.)

And folders in the Dock... Man, oh man. Their behavior really needs to be fixed in 10.5.1.

Nicholas Riley — Oct 31, 07 4923

There is a keyboard shortcut for full-screen mode in QuickLook - command-option-Y. It's pretty amusing to type-select and navigate in the Finder that way, given you only see one item at a time.

Joe Jameson — Nov 03, 07 4946

Thanks for the hint Nicholas. But, command-Y is another shortcut for quick look. And, you will notice in finder if you have the quick look icon in the toolbar that pressing the option key changes the quick look image to a play button. So, command-Y is quick look and command-option-Y is playback (quick look fullscreen). But, command-option-Y does not go from normal quick look view of a file to fullscreen, which is what I thought you were saying.

Andras Puiz — Nov 03, 07 4963

I'll try Command-Option-Y, it may be useful, thanks.
Is there a place that lists all Finder (or system) keystrokes?
I searched Help, but there was nothing.
