Teach Yourself AppleScript in 24 Hours 202

Posted by timothy from the next-week-how-to-cure-all-known-diseases dept.
honestpuck contributes this review of Sams Publishing's Teach Yourself AppleScript in 24 Hours, writing "The market for books on AppleScript cannot be a large one, since there never seem to be many volumes in it; usually only one at a time is up to date and worth the money. Now that O'Reilly's AppleScript In A Nutshell is showing its age (and wasn't that great in the first place), and Danny Goodman's book is even older, I was pleased to hear that this volume had come along." Read on for honestpucks' mixed impressions of the book.

summary Not a bad introduction to AppleScript but leaves off far too early.

Teach Yourself Applescript in 24 Hours (TYA) from Sams Publishing is certainly up to date: it covers Applescript under OS 10.2 and the use of AppleScript Studio to build GUI applications using the language. That's its strength. The book's first weakness, though, is that it starts too far down the learning curve in my opinion. The first few chapters of TYA could be read by someone almost totally new to the Macintosh -- they cover such basics as running the scripts installed with the OS and getting new scripts from Apple and installing them. At the same time, they introduce basic AppleScript programming terminology not really required for these sorts of tasks such as suites, classes and commands. This material would have best waited a few chapters. It is not really until 'Hour 6', most of the way through the first part of the book, that it really sorts itself out and gets down to really teaching you AppleScript.

The Basics

The book is divided into four parts: 'Getting Started With AppleScript,' which covers using scripts and basic programming concepts; 'Writing Scripts With Script Editor,' which takes you through using the Script Editor, details AppleScript syntax and how to script the Finder and various applications and using AppleScript Dictionaries; 'Working With AppleScript Studio,' which covers building AppleScript-based GUI applications using Project Builder and Interface Builder all the way through to complex applications that can store and retrieve documents; and a final section 'Advanced Scripting,' which covers Script Objects, scripting across a network (including SOAP and XML-RPC), and integrating scripts with the terminal and cron.

Each section is then divided up into chapters designed to be worked through in less than an hour ,with a small number of short exercises at the end. I found that most chapters took me about half an hour before I reached the exercises, which then took ten to fifteen minutes.

As you can see, almost everything you could ask for is touched on in this book. Once over the introductory chapters, I found the book to be well laid out, well structured and well written. I particularly liked Part III on AppleScript Studio; it started easily and worked up to quite an advanced little application explaining everything well along the way.

The Bad

There are some things missing, however. Debugging is hardly mentioned (3/4 of one lesson), and debugging is not exactly trivial in AppleScript. I also found no mention of my pet demon with AppleScript; its incredibly strong typing and problems with having data in the wrong type; this is a classic problem with files and file names. In reality, this book teaches you the language without really getting down to teach you how to program in the language. A fine distinction, I know, but after just reading Learning Perl Objects, References & Modules, I found TYA to be light on real examples and real world code. Even the best section, the one on AppleScript Studio, didn't touch on many things you will need to know.

Sams have a page devoted to the book at the Sams web site, but frankly the URL is so long and cumbersome I don't dare risk putting it in a post. Go to the site and type 'AppleScript' in the search box. It has the table of contents and a sample chapter and some of the code from the book. The sample chapter is the third chapter 'Running The Scripts You Already Have' and really doesn't give you a good feel for how the book teaches you AppleScript programming. The page to download the code examples says "All the code developed for the book in one convenient download," but in fact all you get are the AppleScript Studio projects and source from four of the chapters. Oh, and the introduction says "There are even a few goodies on the web site that aren't in the book" -- they sure must be good as I couldn't find them.

In conclusion, I think this book starts too far down the learning curve and leaves off too early, with not enough detail. It seems a shame, what we have here is well laid out and well written, I wanted it to be better after I had finished. This book might suit someone absolutely new to the Mac who wanted to learn enough AppleScript to perform a few basic operations, for everyone else it'll be better to wait till October when AppleScript 1-2-3 will be out from Peachpit and AppleScript: The Definitive Guide will be out from O'Reilly, and we might have a better option. If you absolutely need to get some help with AppleScript Studio then borrow someone else's copy or find one second hand.

        Actually:

        "The Open Scripting Architecture (OSA) is an API that provides a standard mechanism for creating scriptable applications and for writing scripting components to implement scripting languages. The AppleScript component implements AppleScript, the standard scripting language defined by Apple, but developers can also write scripting components for additional scripting languages."

        -- <http://developer.apple.com/documentation/Carbon/R eference/Open_Scripti_Architecture/>

        So you're not restricted to using AppleScript to get those benefits.

        Python, for example, is able to both send and receive Apple Events.
        • but developers can also write scripting components for additional scripting languages.

          That reminds me WHS in Windoes. But the history shows that script programmers on Windows prefer Python and Tcl without WHS.

          • One difference is that (I believe) OSA has been around longer than WHS, and less of an afterthought/add-on.

            As far as I understand it OSA is like WHS + COM (or whatever it is these days). In fact you can even send AppleEvents over networks (if you enable it).

            So, Python + win32 COM bindings is somewhat equivalent to Python + AppleEvent/OSA bindings.

            I think OSA/AE is more integrated into the environment with most applications at least supporting the "Standard Suite" which includes opening & closing docu

      For the people who use it, Applescript is a whole lot simpler than something like PERL. Take a look at the syntax somewhere, you'll see the difference.

      And who are those people? Graphic designers have loved Applescript for a looong time, because they can write stuff for Photoshop without any hassles. Big advertizing departments will often have a huge collection of legacy scripts they've written for various big tasks -- "See the dimensions of all the graphics in this directory and add those numbers, formatted this way, to the end of the file names." They aren't programmers, their minds don't work that way, but they do have large programmatic tasks they need to get done.

      Let's put it this way: I saw that title, "In 24 Hours," and I wondered how it could possibly take that long.

    • The way that Applescript works with the Apple GUI is what makes it interesting to me. I tend to use bash scripts for most things, but Applescript is great for doing "Point and Click" type operations which bash isn't so good at.

      • Actually the syntax of Applescript is its greatest weakness. It is one of those "incredibly easy to read, a pain to write" languages. This was less of an issue back when most applications were recordable. You'd hit record and it would generate an Applescript to do what you just did. Then you could modify it. Right now though only a small handful of Applications support recordability and none of them are the main productivity applications. So it is sadly of little use.

      2 things come to mind...

      First is that Applescript is great for automating Applescript-aware applications (including Finder) without having to either brute-force it, or write whatever function you're after yourself. For instance (I'm working from memory, and it's been a while since I've worked with this stuff, so it's probably not syntactically correct):


      tell "itunes"
      play "Macintosh HD:MP3 Collection:some tune.mp3"
      end tell
      ...and AppleScript takes care of all of the fiddly details of how to communicate with the application.

      Second, this can be done remotely, assuming that AS-remoting is enabled at the target. Which would get really tricky to do with Perl or Python or even Expect.

      IIRC, it would just be a matter of changing the tell to something like tell "itunes" on "Kenny's Macintosh". The rest of the script would remain the same. But then, debugging is a real nightmare...

    • Applescript is an application scripting language. I sure there is YACC/LEX code floating around for the language. So in theory it wouldn't be that hard to port.

      Python, Perl and to a lesser extent Javascript aren't designed for this. (I say lesser extent Javascript, since there actually is a version of Javascript that compiles to the same format Applescript uses and works in the same way)

      Javascript OSA [latenightsw.com]

      One must also point out that there are glue modules for Perl that allow it to do most Applescriptin

      • Just to add to the above, if you use MacPython, they you do get more Applescript-like functionality. i.e. for controlling other Applications. There is some confusion on this since Apple supports the standard Python. MacPython, while using the same language, is technically a different beast. A lot of the language extensions work in MacPython but not the command line Python (and not the variant Python that you may have installed with Fink). Confusing? Yes. But MacPython includes a nice IDE so is useful

    • Because the AppleScript implementation on MacOSX gives you programmatic access to Apple Events. Those don't exist on any other platform. Apple Events let one application communicate directly to an API established by another application. In other words, AppleScript is less a scripting language (like Perl/Python/etc) and more a way of executing a series of Apple Events, with limited additional scripting capability.

      Yes, it's a very niche market, but folks like Pudge have been working on ways to communicate

    • Why applescript?

    • Eh, there's nothing wrong with being good at your niche. While it's handy to have cross platform languages, sometimes there's no need to do so. Actionscript is great for Flash, but would be stupid for system admin, just because it wasn't designed for it.
    • Why Applescript? Because sometimes you are scripting things that are platform specific.

      For example I just finished up part of a Filemaker solution that uses PDF Services in OS X and Applescript to generate, name, and move to a destination folder PDFs from Filemaker records. Picking up the necessary Applescript knowledge to do this took extremely little time compared to what it would have taken me to learn PERL, for example.

      • Python and Perl are great, but you end up typically just embedding Applescripts in them. You can create objects for some AppleEvents, but you then end up writing modules for the Applications you script. It can be done but rarely is worth the effort.

    The book's first weakness, though, is that it starts too far down the learning curve in my opinion. The first few chapters of TYA could be read by someone almost totally new to the Macintosh -- they cover such basics as running the scripts installed with the OS and getting new scripts from Apple and installing them.

    Most Mac users I know don't know or do anything with AppleScript, so I don't think it's a mistake to start where it does. I have the old O'Reilly book which is still great as a quick reference, but I'll have to see this one for myself before recommending it to people. IMO, a lot of people who could really benefit from using AppleScript daily aren't because they feel it's too techy for them. Maybe this book is what those people need. On the other hand, I haven't heard anything about 1-2-3, but I've had good experience with a few of Peachpit's books.

  • Remember Hypertalk, Apple's first try at scripting? The executable syntax was borrowed from COBOL-60. The data structures were worse: "field 3 of line 2 of card 1352".

      You didn't have to refer to the fields and cards by number all the time, you could (and should) give them names and refer to the names instead. Also, as any good programmer would do, you'd use a variable to hold the current card. This is particularly helpful when recursing a stack.

      I still have my HyperCard 2.1 disks and most of the stacks I wrote all saved on quickly disintegrating floppies.

It prepared me for OOP - in HyperCard objects such as buttons are tangible rather than abstract (you can create them, move
  • I've often wondered who uses applescript. Even in the days of OS 9 its dorky syntax never seemed appealing. Now with OS X you can use something like perl. If you use BBEdit you can run perl scripts right from the editor. I would think that the market for applescript is shrinking everyday.

A little ironic that Apple and Apple concerns are such flamebait here on slashdot... First, all computers are Machines.

    The big lie I always hear about Applescript is that: "Applescript doesn't need lots of documentation, it's self-documenting, english-like, and always current"

    While it's true that the little 3rd party documentation out there has major problems (this book, an overly simplistic Jesse Feiler book, an out-of-date Danny Goodman book, and a Mac OS 9 focused O'Reilly reference), I disagree that AppleScript doesn't need documenting.

    Foremost, it needs some strong documentation on how application writers should be writing their AppleEvent suites and AppleScript dictionaries. This is by far the most non-standard, conflicting, and outright stupid place to ignore.

    Apple has made some half-hearted efforts to write some "standard dictionaries" for suites of software, but if you think css and html are under-specified you haven't looked at these "standards". There's no impetus for you to build the entire "standard" suite into your software. I'm not sure that anyone (including Apple) ever wrote software that actually implemented things like the database suite.

    One problem with not standardizing on open, well specified suites is that you can lose all of your script savyness when a key application is discontinued or decides to overhaul their script interface. Those who wrote MacWrite Pro scripts had their work obsolesced overnight when MacWrite was discontinued. Quark scripters are undergoing some pains right now trying to adapt to the new Quark interfaces.

    Of course, because AppleScript exposes your data model for all of your competitors, you'll make things like exporting data out of your proprietary file format a trivial operation if you stuck with standard suites or even if you exposed all of your functionality via AppleScript. So making fully AppleScriptable applications is not something that the big guys want to do with their data engines.

    Beyond standardization though, AppleScript needs a central repository of script dictionaries and plugins. Right now one's Mac will pick out all of the AppleScript dictionaries on your mac, but what you're trying to automate might be 1,000 times easier in GraphicConverter rather than Photoshop, but if you don't have GraphicConverter on your mac you'll be beating your head against a wall trying to force an app to do something it's not good at. The best one can do today is watch over other people's shoulders via web sites, bbs's, email lists, and by downloading scripts others have written. This whole "steal from someone who's done it successfully" attitude is what makes AppleScript centric web sites seem to spiral into oblivion. Everyone's simply reposting what they've stolen off of other sites, the owne's get frustrated maintaining something that doesn't stand apart from the crowd, and it becomes out of date without constant updates.

    I'm not ignorant when it comes to programming, but I find Python and Perl to be syntactically more forgiving and easier to grasp than AppleScript. I find Cocoa to be more standard and more consistently constructed. I find shell scripting to be more accessible and a better "glue" to bind different tasks together.

    I must admit that I still do write the occasional AppleScript and if you rely heavily on a program that supports it well then it can be a decent tool. But it's long fallen from favor as my first choice of scripting.
    • The big lie I always hear about Applescript is that: "Applescript doesn't need lots of documentation, it's self-documenting, english-like, and always current"

      Sadly, this is very true. Apple has really fallen down on the job of documenting AppleScript, and it's always been underutilized because of it.

      When AppleScript first came out, everyone could understand the potential of the feature, but few people really knew how to use it. Apple's AppleScript Product Manager, Sal Sagohian (or however it's spelled),
    • The big lie I always hear about Applescript is that: "Applescript doesn't need lots of documentation, it's self-documenting, english-like, and always current"

      IME, AppleScript's documentation is pretty good. The scripting dictionary built into scriptable apps usually explains things clearly enough-- sometimes if I'm having trouble wrapping my mind around how to extract a specific field from a record, I'll just open up a second window and fool around with a little code until I get it figured out.

      Of course

    Debugging is hardly mentioned (3/4 of one lesson), and debugging is not exactly trivial in AppleScript. I also found no mention of my pet demon with AppleScript; its incredibly strong typing and problems with having data in the wrong type; this is a classic problem with files and file names. In reality, this book teaches you the language without really getting down to teach you how to program in the language.

    This is a very damning problem. One could argue that the O'Reilly book was primarily a reference book. (A reference book dealing primarily with Sys9 and with only a few bits about 10.0 OSX features) But learning Applescript really ought to deal with how to code Applescript.

    It is sad that there are not really good books on Applescript. While the language itself is pretty poor (IMO) the concept is excellent. Applescript Studio, while flawed, is a great tool. Most significant, with OSX, you can mix scripting languages to do very powerful things. i.e. most of my scripts are combination shell scrips and Applescripts. I also have a lot of Python/Applescripts. With Apple's GUIScripting additions to Applescript it is an amazingly powerful tool.

    The only downside in Apple's toolkit are fairly weak scripting support in some important applications. (cough) Mail (cough). The other downside is debugging, which is surprisingly weak.

    If I had a wish, it would be for something like Applescript studio, but with solid debugging and support for shell scripts, Applescripts, Perl scripts, Python scripts and maybe even TCL/TK. It would really be a killer feature for Unix types.
