Creating Applications with Mozilla

Peter Wayner writes "The book Creating Applications with Mozilla did not set out to capture the essence of modern open source software development in a few hundred pages, but it comes closer to that unreachable goal than almost any other book I can imagine. Everything is there: the proliferation of acronyms, the funky names, the endless layers, the earnest collaboration, the unstoppable yearning for customizability, and, of course, plenty of source code. The book is just supposed to be teaching us how to turn Mozilla into a front end for everything, but it's really a distilled exhibit of all that is hip and now in code creation." Peter's review continues below. Creating Applications with Mozilla author David Boswell, Brian King, Ian Oeschger, Pete Collins & Eric Murphy pages 454 publisher O'Reilly rating 9 reviewer Peter Wayner ISBN 0596000529 summary How to use the Mozilla APIs to do anything.

On the first and most obvious level, the book is just the typical, thorough treatment of the important APIs that we've come to expect from O'Reilly. There are chapters addressing all of the important layers of the Mozilla platform and plenty of examples that show you how to customize the platform. Some may want to change the icons and others may want to add more robust features. The range of possibilities is surprising and coders are creating one-to-one communications enhancements, add-on widgets, and even games. There are certainly some things missing, and some areas that could use more detail or more complicated examples, but the book is already 454 pages long.

On another level, this book is also one of the first finished documents that explains what the Mozilla group has really been up to for the past five years. Some have abandoned the project, and others have attacked it as fundamentally misguided. This book shows why it took so long by demonstrating all of the cool features added during the long march to a new, thoroughly extensible architecture.

Are the results enough to justify the time and the effort? Some note that the features may be a bit overhyped, because building your own browser with the Mozilla API is like making a pizza with $15 and a telephone. While there's a large part of the book devoted to the work you can do to change the look and feel of the buttons on your browser, the book and the project offer much more. The Mozilla project is one of the biggest threats to simple tools like Visual Basic to come down the pike in some time. The various layers offer many ways to provide good, customizable interfaces to databases, the web, and much more. I can see how many corporate development shops may want to start making Mozilla the platform for a license-free front-end, simply because it's a straightforward tool without extra costs or restrictions.

At the most abstract level, the book is a great way to get a taste of modern software development. Computer scientists sometimes fix problems by adding more and more layers of indirection. This may not solve anything, but at least there are hooks for a real solution to use some time in the future if some one ever does figure out how to make the box do it. The Mozilla browser is one of the most extreme examples of this philosophy to ever emerge. Emacs was something special, but this is even more insane. Everything can be changed around by rewriting some XML and Javascript and most people don't need to juggle the pointers in grubby C to do amazing things. I realize it's not as beautiful as Lisp to some, but it's got a clarity and level of abstraction that's stunning to behold. Lisp was just procedural, while XML is more like logic programming.

This relentless customizability embodies one of the deepest reasons for the success of open source. Technology is inherently complicated and the only way we can use it is if we can look under the hood. You can say all you want about CVS trees and bazaars filled with competing code, but opening up the interface is one of the most powerful themes of open source. It's not about teaching people to build their own VCR or PVR from scratch, getting the VCRs for free or even debugging the VCR's source code -- it's just about making them easy enough to program.

The book illustrates how Mozilla opens up the API to create a relatively easy language for people to use. The real open source is not the C in the tar ball, but the XML interface spelled out in the book. Many people feel that the most important thing that the first browser designers did was make it easy for people to see the HTML tags marking up the document in front of them. The new Mozilla takes this transparency to a new high.

If you look at the book at all of these levels, you can see that this is one of the most important documents to emerge from the open source community in some time. At first glance, it's just another set of APIs for us to wiggle. I realize it's not fair to credit the Mozilla team or the book authors with creating the browser or XML ex nihilio -- they just jumped on some of the most popular bitwagons propagating across the Net. But the result is a stunning completion of a very important and cohesive vision. The book doesn't crackle with bleeding-edge novelty, but shines with the certainty of a job well-done.

    That niche is an HTTP-friendly GUI browser with *optional* scripting capability to have *some* local Turing-complete application programmability sprinkled in. IOW, get right what HTTP+DOM+JavaScript could not get right.

    But, if they make it a fat-client client-server tool, then slap them with a wet Visual Basic box.

    Dude-- read the review. Here are a few sentences from the top: On the first and most obvious level, the book is just the typical, thorough treatment of the important APIs that we've come to expect from O'Reilly. There are chapters addressing all of the important layers of the Mozilla platform and plenty of examples that show you how to customize the platform. Some may want to change the icons and others may want to add more robust features. The range of possibilities is surprising and coders are creating one-to-one communications enhancements, add-on widgets, and even games. There are certainly some things missing, and some areas that could use more detail or more complicated examples, but the book is already 454 pages long.
    Sounds like he talks about what can and can't be done with the code samples and even a bit about a few of the individual chapters. He just didn't do one of those boring Slashdot reviews that goes through each chapter one by one. I can get the chapter breakdown from the book's website.

    And if you ask me, knowing what to do with the XML is pretty important. If the Mozillians are smart, then that means there's something of value int he book. I really don't want a well-written, witty book about how to write assembler code. Dis

    Yeah. You call the dll's directly. You can use any of all of the functionality in IE, and yes, it is distributable. I don't remember the names of 'em now, but there are several to use. And yes, you can customize it however you'd like. You can do a web browser window, do whatever buttons you'd like, however you'd like. I have one tool which is does something automatic, and doesn't even have a GUI. You can absolutely embed and customize it. Check out the details at MSDN. Hell, I'm looking at Quickbooks 2002 which is built around IE. They just use it for the rendering... no actual browsing per se.
    I use a customn app that I wrote that is completel automated using the XML object that comes with IE. You don't need the source since you have access to every possible property/method in every DLL, and they're all documented. If you have to muck with the source, that's because the program itself doesn't work, or has a shitty API. IE works and has a very extensive API. Has for years.

    And no, of course you can't use it on Solaris. But, I'm not aware of a whole heck of a lot of products that would need to be ported to Solaris (Quickbooks for Solaris? I don't think so.).

  43. Data based GUI by samwhite_y · · Score: 3, Interesting
    I have been wondering when the first truly "data driven" solution would be created for standard heavy client GUIs. HTML created a standardized approach to simple "Info" presentation (and submittal) GUIs. Even though the primary goal for HTML was quite limited, this idea of having a "data" driven solution to info presentation has been such a hit that it has generated huge and powerful scripting solutions all devoted to enhancing this one simple GUI idea. It seems obvious to me that almost all facets of an application should be data driven in a similar way, including all GUI presentation in heavy weight applications. In a truly modern application environment, all code that determines placement of GUI elements and the simple logic that binds them together should be done in an HTML style environment (or its cousin XML). This data driven approach should be so pervasive that much of the higher-level logic of an application should be in data and script.

    I laud Mozilla for going down this road and it is clear to me that the core developers for Mozilla are a step above your standard programmer. Some accuse Mozilla for not following a method that would create "standards" for their XML GUI description language, but I have found that the successful "standards" usually follow already adopted and reasonably mature technologies. You do not know how you want to design something until you have done it, used it, and given it to other people to play with. Only after an application has grown sufficiently to include all the thousands of unexpected details is it sufficiently mature for people to talk about standards. For example, I consider the EJB specification's largest failing is that they tried to standardize it before it was actively used for a couple of years. Only now that we have some mature app servers do we really have an idea what needs to be in the core EJB specification. If EJB had followed this road, maybe application developers would not need to use vendor specific code for the critical parts of the functionality. Like OO, the mantra of "standards" seems to be more of a marketing tool to get Fortune 500 companies to cough up millions of dollars than something that really influences how sophisticated and successful applications get developed.

    I have my own questions for the Mozilla team. How do you deploy "overrides" of existing configurations. Suppose I want to deploy a "batch" of changes that I want to turn on or off. Is there a way to create configuration "layerings" in XML files so a group of data specifications can be conditionally included from a set of external files? How much scripting is allowed in these files? If I want to write conditional code for specifying a color (such as a color choice per day of the week), is there a way to write scripting solutions for that need? Of course, I could read the book but I am lazy and I suspect that it would not give a full answer.

    *sigh*

    All that IE does for Quicken is allow Quicken to use it as an HTML renderer. This is much different than Mozilla which can create a standalone application. The Quicken developers had to use C++ of VB or whatever and embed the MSHTML control into it. Mozilla does not require anything in addition to the package itself to create a new application. So even though this isn't necessarily new, it's definitely a lot more than IE can do on it's own. Plus you can embed Mozilla into apps like Quicken as well. Topstyle does a great job of integrating IE and Mozilla side by side using this technology.

    I've read several chapters of this book and I'm trying my hand at Mozilla app development. I'm mainly interested in it for "better" web applications. HTML was never designed for that kind of thing, and I'm frankly tired of it being used for such. Mozilla+XUL can make applications that load like web pages but whose interface is more like traditional desktop applications. Rock on!

    I really DO believe that Mozilla has a bright future in this regard. It provides some great tools. I about wet myself when I discovered the Javascript Debugger! As the article says, it will provide a totally free/Free way to deploy custom applications.

    It's also a potent tool against IE's monopoly. If there's one thing that can cause people to switch from IE to Mozilla, it's applications that only work in Mozilla! I used to support the "Best Viewed with Any Browser" campaign (which is still appropriate for pure information) but I have since realized that because Mozilla is Free, open, and cross-platform, there is no need for anything else! I now encourage people to develop web-based applications in XUL.

    I do have a few small gripes with it. Textboxes don't wrap like they do with HTML's "wrap=soft" attribute. That's bad. I asked in a newsgroup and was told that this functionality would be in Mozilla 1.2.

    Also I was hoping to embed an HTML editor in my application, so that people could post HTML in their comments and have a fancy editor for them. To my dismay, it appears like the HTML Composer can ONLY be embedded in local chrome:// apps, not in those served by HTTP. Anyone know a way around this?

    It's a little different if you are talking about accessing client-side data sources. Mozilla/XUL is (kind of) a virtual machine (VM), meaning it doesn't intrude too much upon the client's OS. But, XUL/XPCOM has bindings for all kinds of programming languages, such as C, C++, Perl, Python, Ruby, and the list keeps getting longer (Good intro here). Thus, on the client-side you can use the database capability of any of these to talk to the Mozilla elements. I'm sure it wouldn't be too hard to whip up just a little communication between Mozilla and ODBC ;-).

  49. Constructive criticism. by rice_burners_suck · · Score: 3, Interesting
    What I don't get about Netscape and its developers is... Why do you folks think that the browser must be the front end to everything? Why shouldn't, for example, a text editor, or email client be the front end to everything? As far as I am concerned, the operating system has evolved to be this front end that everyone is looking for. Back in the day, the operating system did mundane, boring things that users didn't want to think about. But now, the operating system is expected to do everything, plus make cappuccino. So why do we need yet another (entirely too bloated) layer--the web browser--on top of the operating system? A web browser should do just that: Browse the web. Email should happen in a separate program. News in a separate program too. IRC or whatever in yet another separate program... The fact that web browsers need to provide the ability to interact with web pages doesn't necessarily mean that the entire world must work over HTTP port 80. Because there are 65534 more perfectly good ports to work with, and for a good reason.

    I would like to relate a recent experience with NETSCAPE 7.0. Please excuse two paragraphs or so of background information...

    Those who have read my literature (/. postings) in the past will know that I HATE Windows because it is TRASH. But unfortunately, my mother's work requires her to use Windows due to a proprietary application they use that isn't available on an operating system that actually works. So she has this laptop with Windows XP Home Edition. Now I'll admit that for the rare cases that I must use Windows, there's a crappy old box around here that's running Windows 98 SE. It's pretty crappy, but I removed pretty much all the superfluous junk from the installation, so it doesn't crash more than once in a blue moon^H^H^H^Hscreen or so. So while 98 is not my operating system of choice, it's admittedly not quite THAT bad when there's no other way to get the job done. I've had very minimal experience with setting things up for people on 95, 98, Me, NT, and 2000. All of them were crap. 95b was the best one (it could run for up to six or seven days without a reboot), but doesn't run on new hardware. 98 SE is somewhat usable. Me was probably the worst one I had seen so far... Everything is so complicated, cluttered up, and messy. But then my mother asked me to "make the internet work" on her laptop... And it's running XP.

    Now I do have to admit that I was impressed with ONE aspect of Windows XP: You plug in a network cable; it recognizes it and you're on the network. You plug in a ZIP drive, it recognizes it and that's that. You plug in a printer, it's automatically added to your printers thing. I wish somebody'd reverse engineer that and make it work on operating systems. But that was the extent of my good impression. The rest of XP is GARBAGE!!! The multiuser aspect of it is really clunky and crappy. The graphics are REALLY ugly; I had to revert it to the "Classic" look before my vision got damaged. The sounds were as stupid as ever; I had to delete them all. And the thing was as unreliable as software from Microsoft. Oh wait... That is from Microsoft. Guess that explains it. :)

    But I digress... So back to *N*E*T*S*C*A*P*E* I installed Netscape for my mom, because Internet Explorer is trash. Netscape, in my opinion, is lacking in many areas (such as usability), but I'll classify it as software, rather than trash. So I installed it. The install went along pretty smoothly and before I knew it, I had Netscape launched. The new graphics are MUCH nicer than the extremely crappy ones in Communicator 4.x. But the initial screen was SOOOOOO cluttered!!! Buttons and tabs and side bars EVERYWHERE! As an experienced user of computers and web browsers, I couldn't hear myself think, so to speak, in all this optical noise. I immediately turned all that crap off and modified all the settings to my liking, so that my mother, who has much less experience than myself, would actually be able to use the damn thing. And then it happened. The next time I launched Netscape, everything locked up and the disk started crunching and grinding away like there was no tomorrow. Even the ctrl-alt-delete window took forever to show up. I ended up forcefully shutting off the power, because I couldn't even log out. (Yeah yeah... File a bug report--but do you HONESTLY think that my mother knows what a bug report IS, let alone knows how to file one?!!) And this is where the background information on XP comes in... I guess it REMEMBERS what made it crash and when you reboot it (or log out and log back in) it does it over again, consequently putting itself in the same situation and locking up again. That's what happened. Whenever I logged into my mother's account, the whole computer became so unresponsive (from the grinding and whatnot) that I couldn't even open up the huge, cumbersome Start menu. (Mafiasoft. Where do you want to pay today?)

    I noticed that the other account, that I had originally set up for her out of the mere habit of always giving myself three or four accounts on my BSD boxen, still worked fine, so I logged into it, created yet another new account, moved all her files over, and deleted her original account. Oh yeah, and I removed Netscape and purchased a copy of the newest Opera 6.x for her. Sure, its initial screen is a bit cluttered and I have a few complaints about the increasing complexity and proliferation of seemingly unnecessary features (that other people probably want, just not me), but it's small, fast, and it WORKS. Extremely well, I might add. (It's what I am using right now under FreeBSD with Linux compatibility turned on.) Now she's happy as can be... And I know for a FACT that I will not buy a computer with Windows XP. And I am pretty disappointed with Netscape once again (not so much for the crash, but very much so because of the clutter), as I have been for several years. (Yes, I will continue trying it from time to time, because somewhere deep inside, I believe that it will BECOME a very good, reliable web browser. I just wish it'd become as SMALL as Opera (3 megs or so) and as fast. Netscape is very, very slow.)

    I hope if any Netscape developers are reading this, that they'll take this as constructive criticism rather than as flamebait. Oh yeah. And YES, I know the Gecko engine is found in Galeon and several other browsers.
