RE: MX opinion!!
I love the re-tooled Debugger. Just being able to expand and collapse my lists is terrific. I like to orient the Debugger pane at the bottom of the Script window. That way, when the Script window switches over to debugging at the breakpoint, I don't lose my place. The script doesn't shift, and I'm right where I want to be. But, like the release notes state, the Debugger font is downright puny and nigh-on unreadable at 1600x1200. Is there any way to change the font for the Debugger?! The split-pane Message window is fantastic, too. I like seeing the results of calls I make from the Message window without having my output obliterate my input. It's just a little thing that makes a big difference. I'm quickly getting used to panel grouping, too. Being able to save those arrangements, and call them back in, is wonderful. Docking doesn't do much for me. I like to maximize my script windows as much as possible, so I leave my essential panels undocked so as to have as much client window space as possible.

Watchpoints
Whenever I wanted to create a "watchpoint" in Lingo, I would do this... if (liValueIAmWatching = 1234) then nothing end if ...and I would place a breakpoint at the "nothing" line. I reasoned that the Watcher window wasn't ever going to help me in this regard because it just "watched" the variables, it didn't "break" when the variable was set to a certain value. How does everyone else do watchpoints? You know, where you can just let the scripts rip, and then a break will occur only when a particular condition is met. How about writepoints and readpoints, where a break occurs whenever a read or write from/to a variable occurs? Goodness knows pretty much all of us have worked ijn debugging environments that provide this capability. Share your secrets!

Quickie Port for Lingo and C Expert!
Here's a good one. I'm having trouble with this. Maybe someone would like to
take a stab at it for fun!
Below is some C source for a relatively simple function that generates a
series of three stellar magnitude deltas from an input floating-point value
(along with a main test routine). I need to duplicate this function
precisely in Lingo. I know it can be done. It's the pointer math that's
getting to me!
If you're feeling altruistic today...give it a shot!

/* The following function takes a (B-V)T value, i.e., a B-V color in
the Tycho magnitude system, and computes from it V-VT, the difference
between Johnson V and Tycho V; the corresponding B-V in the Johnson
scheme; and V-Hp, the difference between Johnson V and Hp (Hipparcos
"magnitude") for the input color.
I got the raw data for this from Brian Skiff, who posted them on
the Minor Planet Mailing List (MPML) with the following comment:
"...To get standard V and B from Tycho-2, it is probably best to use the
relation shown by Mike Bessell in the July 2000 PASP... Bessell does not
give
an algebraic relation, but instead shows a cubic spline fit with a look-up
table... I have copied out Bessell's table below as a flat ASCII list."
In what follows, values for (B-V)T away from the lookup table
points is computed using (again) a cubic spline. The functions vary
with sufficient slowness that this ought to be accurate down to the
.001 mag level.*/

As far as Macromedia's tracking databases are concerned, it shouldn't be.

RE: Efficiency Questions
Thanks, guys! Always a big help. My overheated benchmarks show that the chars() function is the winner by as much as a 24% margin. Thanks, Buzz, for the reminder about .ref. In my application, however, I'm hardly doing any multiple accesses of the same chunk, so I don't have a strong case for using that property right now. The only reason I threw in the property list version of the two-value return is because it made better visual "code sense" at the re-access point using .h and .v, rather than [1] and [2]. It was clearer what each value was. Still, I'll probably just stick with the simple linear list approach. Faster ands smaller. The values aren't used as a point in the context of Lingo (they represent a location within the SVG coordinate plane), so I'll refrain from incurring the overhead of points.

RE: Numeric Range Search in List
Here's the original problem, guys. And, by the way, thanks for the shared brainpower. I'm using Lingo (and DOM-Lingo) to generate SVG documents for each of the Guide Star Catalog (GSC) regions within the Tycho-2 Star Catalog. Essentially, I'm generating a TON of very detailed star charts for viewing in the Adobe SVG Viewer. There are 9,537 regions defined by the GSC to cover the whole sky, and the Tycho-2 database uses those regions to primarily identify and catalog its stars. The Tycho-2 Main Catalogue has 2.5 million+ stars, and they are ordered in the database by region (which is nice -- makes things real easy for this phase). I'm generating an SVG chart for each of the regions -- averaging over 200 stars per chart, but up to 600 stars per chart in the regions covering the Milky Way. Lingo reads the delimited database records, parses them, and does all the math for position and magnitude (cx, cy and r attributes for elements, if you know SVG). DOM-Lingo builds an SVG DOM tree for each region, and the serialized XML is spit back out into a "GSC.svg" document. The values of the "bounding box" list elements that I detailed are actually the min and max Right Ascension and Declination, expressed in decimal degrees, for each of the 9,537 GSC regions. The R.A. values run from 0.0 to 360.0, and the Decl. values run from -90.0 (South Celetial Pole) to +90.0 (North Celestial Pole). Now that I've progressed past the star plotting phase of this project, it's time to tackle the galaxies (and then, eventually, the nubulae, clusters, radio sources, etc.). The Catalog of Principal Galaxies (PGC) contains positional data for over 77,000 galaxies, but it is NOT cataloged or ordered according to GSC. Therefore, in order to make the appending of the galactic data to the existing SVG documents easier and quicker, I'm going to have to tranform the PGC database into a positionally ordered GSC-compliant format. That way, I can then work with the chunk of galaxies that lie within each region, in order. I have to read and parse the SVG document for the region, use DOM-Lingo to tack on the new galactic elements, and then reserialize. To do this first-step conversion, I need to take the R.A. and Decl. coordinates for each galaxy and match them up to the corresponding GSC region in which they lie. For each galaxy I read from the PGC, I'll append its raw data to the end of the corresponding intermediate region file. I'll then concatenate all those intermediate regions files into a single GSC-compliant database file, which I can then use to modify the existing 9,537 SVG documents. If I were to simply walk through the PGC, line for line, in the order that it is currently in, and open/parse/append/serialize each galaxy into its corresponding SVG region document, it would be take a whole heck of a lot longer to do it than if I had an entire region's worth of galaxies to slap onto them. So that's why I need to determine which GSC region a particular set of coordinates falls within. The GSC regions are only defined by their positional extents in the sky. I have to find where each galaxy goes. Thus, I need a good way to determine that, based on the list of region extents that I have. -Christopher -Original Message- From: Colin Holgate [mailto:[EMAIL PROTECTED]] Sent: Thursday, June 27, 2002 11:38 AM To: [EMAIL PROTECTED] Subject: Re: Numeric Range Search in List >tX = 124.357892 >tY = 20.736474 >tPoint = loc (tX,tY) > >repeat with i = 1 to myBigRectList.count > if tPoint.inside(myBigRectList[i]) then . >end repeat This is the approach I would have suggested, except it would still be up to 9500 repeats of the inside test.

Numeric Range Search in List
OK, I need a little guidance here. I have a list with 9500+ elements in it. Each element in this big list is a four-item list which acts as bounding box limits. Looks like this... [[0.0, 2.5, 0.0, 2.5], [2.5, 5.0, 0.0, 2.5] ... [350.0, 360.0, 88.5, 90.0]] The first item in each internal list is the minimum horizontal value (the left) for that particular bounding box, the second is the maximum horizontal value (the right), the third is the minimum vertical value (the top), and the fourth is the maximum vertical value (the bottom). Then I have two floating point values, which act as x and y (or h and v) coordinates, like these... 124.357892 20.736474 What I need to do is search the big list for an element which contains a bounding box within which BOTH the floating point values would physically lie. For example, if I were to successfully find the "box" element in which 124.357892 and 20.736474 resided, I might find the element [122.5, 125.0, 20.0, 22.5]. That specific "box" element contains the horizontal coordinate (124.357892 falls between 122.5 and 125.0) and the vertical coordinate (20.736474 falls between 20.0 and 22.5). I hope that makes sense. Important: There is only ONE bounding box in the big list in which the coordinates will lie, and there will always be ONE. The bounding box values are not in numeric order of any kind, and it can't be reliably sorted in such a way that a binary search can be implemented on this. What would be the speediest way to perform this search? I'm sure there's a tricky way to do this. I just can't come up with it. ¯¯¯ Christopher Watson Sr. Software Engineer Interactive Web Media Lightspan, Inc.

That's pricisely the kludge I'm running now. And it works, so I'm not going
to fight it any longer. The QA Mode status text sprite is on-stage, but is
shrunk to a height of only a few pixels (so that no text shows), and the
scroll bar (which is evidently necessary) is just barely off-stage and not
visible. At the point I need this, it doesn't show anything.
>I presume you are not doing this in your parsing, etc.?
>
>repeat with var = 1 to blah.count
Well, Buzz...the parsing is long since done at the point of my problems. The
parsing is a split second thing earlier in the start-up of the engine.
There's just some DOM access going on in the object creation loop -- no
parsing, per se, going on -- and the repeat block iterates to a maximum held
within a property variable of the ItemManager object:
property miNumItems
miNumItems = goXML.getDocumentElement().getAttribute("NumItems")
repeat with i = 1 to miNumItems

Lingo Gurus! Problem Solved...For Now...
Thank you, everyone, for your help. After much consternation and consideration, I tried placing another instance of my "Status" text member onto the stage in a separate channel. I assigned a small behavior to that sprite to make it visible only in Release Mode, shrunk the height of the member to the point where no text showed within it, and nudged it far enough to the right to place the scroll bar off the stage. I then modified the behavior attached to the original "Status" field sprite to stretch the height of the text member back to what it should be for QA Mode only. I now have the speed I need, without showing anything new on the stage, and without breaking QA Mode. Super-duper kludgey...but, hey...it works. I'm not asking any more questions. Just praying QA passes it. ¯¯¯ Christopher Watson Sr. Software Engineer Interactive Web Media Lightspan, Inc.

RE: Lingo Gurus! Need some Input!
>Does the text-fix also work if the member is not on the stage, or >not even in a sprite? No. The sprite needs to be on-stage and visible for the speed-up to occur. -If it only 'fixes' while on the stage, then it might have to do with the sort of 'mini-updatestage' i anticipate is happening when modifying staged text-members. Sounds right to me, but I can't put any other text sprites on the stage, because it's not in the design spec to do that. I wish I could, but I can't. -Does a regular 'updateStage' also introduce a fix? No. It doesn't. That was the first thing we tried. -Have you tried to eliminate conceptual parts of your test, ie: is it the number of objects alone that grinds, or is generically using ancestry, or is it specific to some of your complex code - say DOM-XML? Yes. I have strategically commented out and/or segregated chunks of code to other repeat loops in order to pinpoint where the slow-down is actually occuring, and it is indeed a result of my object creation and complex ancestry tree. I took out the calls to DOM-Lingo, and that definitely wasn't the problem, either. It's really looking more and more like a by-product of my complex architecture. ¯¯¯ Christopher Watson Sr. Software Engineer Interactive Web Media Lightspan, Inc.

We ran a test that left the text sprite on-stage, and wrote into it in Release Mode just as we do in QA Mode. But as far as we can tell, the speed-up only occurs when that text sprite is on stage and visible. And we simply can't have that in Release Mode. It's not part of the design. Hoping that updateStage (or otherwise making visual changes to that which is on-stage during this initialization process) would kick the speed up, we tied the object creation loop into the progress bar that is already a part of the engine start-up. No dice. Even making that update once within each iteration of the loop does nothing to kick it up. So it's not tied to writing to the stage or updating it. It's looking more and more like it's all about the ancestry tree I'm creating. It must just be too complex for these slower, older machines.

Lingo Gurus! Need some Input!
Alright...I need some help from all you high-caliber dudes and dudettes regarding an strangeity we're seeing in our Shockwave activities. During the initialization of our Shockwave-based testing environment, I'm creating a slew of child objects from within a repeat loop within the "new" handler of a parent script at the time of creation of another child object. The child object in which the repeat loop resides is actually an ancestor of another object. The main global child object, when created, assigns the ancestor property to a child object it creates. That child object then runs through a repeat loop which can, depending on the test being administered, create up to 19 other child objects, storing them in a list property within itself. Each of these other child objects ancestor themselves to other objects they create, and those to still others, and those to still others. All in all, we're talking about one object ancestoring to another it creates, then creating a list of others, which all ancestor 4 levels deep themselves. Each child object in this whole sheme is calling DOM-Lingo API to gather vital info from the input XML which describes the test. In a nutshell, it's a complex inititialization web. On faster machine, running more modern operating systems, the whole process is pretty fast. In fact, the phase of initialization that actually involves all of this child object creation whizzes by, usually in less than a second. On lower end machines with older operating systems, however, this object creation phase is slo-o-o-o-o-o-w. Maybe not right at the outset, but according to my debug window, the whole process slows down logarithmically. It's almost acceptable, the pace at which the repeat loop executes at the beginning of its iterations, but gradually slows down to a snails pace at it progresses. By the time we get around to creating the 10th, 15th, 19th object, we're chugging at about 3 or 4 seconds for each loop. Not acceptable. The lower end machines I'm talking about are, for example, Windows 95 and 98 machines on 233 MHz P2's, with either 32 or 64 MB of RAM. On my W2K box, which is a PIII 500, it's screams. No slowdown. These child objects I'm creating, they are not memory hogs. They don't do much more than create other smallish child objects, and call out to DOM-Lingo to get info from the XML. Memory is NOT in bad shape while this is going on. And here's the real kicker, guys. When I run my engine in what we call QA Mode (where I display a text sprite into which I place debug strings as it runs), it runs lickety-split on the low-end machines, too! The only difference between the "release" and the "QA" modes is that text sprite, and that I'm putting text into it as the repeat loop runs. There are NO OTHER programmatic differences between the modes. Now, I need to also say that I have already produced a version of this engine that breaks the repeat loop out into a two-frame loop that repeatedly calls the second child object (after it is created) to create this list of other child object. Naturally, I thought that if I departed from my "repeat loop" ways, and let the playback head drive the creation of these objects, the engine would snap out of it and get through the loop a lot quicker. I figured that I just need to give the engine some "main application loop" time. But that didn't do a thing. No change. I'm bamboozled. If it's not memory, why is this object creation process bogging down? And morfe importantly, why does it NOT bog down if I'm writing strings to a text sprite? Please help.

Time Stamping in Code at Publish Time
Here's an interesting one. We've got several development and R&D servers onto which I deploy the DCR I produce. The manual deployments happen relatively irregularly over the course of a week or so, and then the DCR is intergrated into a site build that is installed onto other servers at other times. Depending on the time of day, one set of servers may have one version of the DCR, and another set may have another version. Eventually, a specific version is tagged as a build candidate, and it gets packaged up in our build process and installed on the QA boxes for testing. The DCR can be run in a "QA Mode" that displays several bits of information in the stage area for testing purposes only. One bit of info, which is very important to the testers, is the "Submission Level". That's simply a letter (A, B, C...and so on), which is manually incremented in my "startMovie" handler each time a I publish a DCR destined for the build and a submission into QA. We track our defects (bugs) using the Submission Level as the key for regressions, etc. But at the development and R&D boxes, there may be several versions of the DCR deployed during any given day, and it becomes important for the content reviewers and production people to know EXACTLY what version of the DCR they're looking at. It becomes even more important to ME when the content and curriculum people approach me wondering if the version they're looking at has that one little fix I implemented earlier in the day...or not. I don't have any way of telling them if it does, because all we can see as a result of running it in "QA Mode" is a Submission Level letter. For these particular servers, that's just not enough info. I need more granularity in my versioning display. But I do not want to have to increment or edit a string in Lingo every single time I publish the DCR (which is dozens of times per day). I need some sort of automated way to get my DCR the information it needs to display a "version" tied to the specific instance of publishing the DCR. How can I do that??? I really wish there was some message sent to movie scripts whenever a DCR was about to be published, so that I could alter via Lingo the movie script that contains my version string. I could insert the current date and time, and have that available via a global variable at runtime. That way, I could also display the "publish date and time" of the DCR when it was run in "QA Mode". Anybody got any tricks up their sleeves for doing this sor of thing? Any alternative ways of looking at this problem?

Thank you Cole, Irv and Luke. Cole, you were right. There are some tangible speed-ups when going to "old school" over "dot". I'm converting my entire DOM implemenation, because it's definitely worth the effort. Irv, those were some terrific suggestions. I'll put the delimiter string length into a local var and work with that. I had already tried the list variation on the set of delimiters, but didn't see any substantial gains there. Now, using the itemDelimiter to "chunk" the tokens out is an idea that I think has some potential. I'd just have to figure out how to successfully make it recursive for all the delimiters, while maintaining the proper order in the resultant token list. I'll look into that.

Tokenizer Optimizations Anyone?
Hello friends. Below you will find the properties and "new" handler for my string tokenizer. This object takes a string, and a collection of delimiters, and splits the string into an internally maintained linear list of tokens, based on the specified delimiting characters. I'm looking for ANY ways to optimize this "new" handler, without having to resort to TextCruncher or any other Xtra. I'm sure the handler is understandable, so I don't need to go into great detail to explain it. Basically, any number of delimiting characters can be sent in, so the search needs to take all delimiters into account. Obviously, it needs to find the nearest occurance of any one of the supplied delimiters, and then needs to add to the linear list the chunk of text between the current search point and the found delimiter. I'm currently hacking the front off of the supplied text with each find, so that I can use the offset function to locate the next nearest occurance of a delimiter. I just want to know if there's a better way to do this.

RE: XML with unkown amount of children (Follow-up)
To add, Matt:
The alternative (and actually preferred) method with DOM-Lingo would be to
just create a TreeWalker, with the element as it's root. Here's all the
code, from parsing to walking:
loParser = new(script "DOM_Parser")
loParser.parseString(lsMyXML)
loDoc = loParser.getDocument()
loB1Elem = loDoc.getElementsByTagName("b1").getItem(0)
loWalker = loDoc.createTreeWalker(loB1Elem, #SHOW_ELEMENT, VOID, TRUE)
loChildNode = loWalker.firstChild()
repeat while not voidP(loChildNode)
-- work with the child node here
loChildNode = loWalker.nextSibling()
end repeat
The repeat loop would walk through all the children of the element
(which is the parent root), and the call the loWalker.nextSibling() would
return VOID when there were no more siblings.

Subject: XML with unkown amount of children
'Lo all,
I was just wondering if there is a Lingo test I can run on an
xml object to determine the number
of children contained within a particular level.
For instance, if my document look as such:
<1a/>
<1b/>
<1c/>
Is there a function (or a way to find out) the number of
children contained in b1? Basically
I want to run a repeat loop through all children of a given
node, but that is a little hard
when I do not have a number to end on.
Thanks in advance for any help.

RE: Ancestor Limits?
Thanks, Kerry. My chain is currently 7 deep, and I, too, am having no problems at this point. So I guess I won't worry.

Some of my objects have an ancestor chain 6 or 7 deep. Granted, that's no where near maxInt, but it is a fairly complex chain, and I've had no problems. At least not with the ancestor chain ^_^ One bug I found, though--a sprite with two behaviors with a common ancestor. The ancestor was processing things like stepFram, so the sprite was processing some events twice.

Ancestor Limits?
Are there any limits to number of "generations" you can create in an ancestor chain? Christopher Watson Sr. Software Engingeer Director/Shockwave Development Lightspan, Inc.
