Re: the := operator (affectation
I haven't been following this thread closely, but the impression I've got is that the arguments have centered around whether: var gets val, or an equivalent is acceptable xtalk *style*. I would say that var gets val conforms to the spirit of xtalk, but unfortunately it does not conform to the syntax, because you cannot start a program line with a container name. At present that is a syntax error, regardless of any operator that you might type after it. A line of transcript must start with a command or keyword, so to be compatible the command would be constructed like: gets A=1 or something along those lines. And all that is achieved is that you can type = instead of into. (The local command can actually take this form of course). Martin Baxter Dennis Brown wrote: Dar, I am not arguing for =, I am arguing for gets and some shortcut that suits, if any. Gets is a cousin of get command that is already a left assignment operator. It does not introduce a new concept to the syntax, but just makes the get construct more general. I actually find it a bit awkward when I have used the get x construct, then decide later to use another variable instead of it. The editing is a lot more than just changing variable names.I have even taken to put x into it on occasion, just so I can more easily change my mind later. I would be happy to be able to change get x to myVariable gets x.

That could be expanded to the general form it gets x. Now we have a general xTalk flavored version using the new gets keyword. From there just substitute any shortcut for gets like gts or =. There you have it. Elegance, consistency, and brevity! There is nothing elegant about = for assignment. IMHO, := is much superior and is less offensive. In mathematics = is a relation or sometimes a function or sometimes used in where or let syntax (named value scoping). Commands in xTalk follow the English implied-you imperatives. The deviation from that to a descriptive of the dataflow does not fit. I come from a functional programming background, but I accept the imperative style.

Nobody *likes* RegEx. But it is powerful, and we use it because there is no practical alternative. I wish there were. An assignment operator is a different kettle of fish. I'm against adding an assignment operator whether it be = or := because it would add a fundamental change to the way statements are structured. (I.e all xTalk statements begin with a command in the form of a single word imperative.) I'm not against fundamental change if it adds something substantially new to the language, but in this case the purpose is just to save a bit of typing. The downside is potential confusion among new users (and old ones for that matter). For example, put x into y is used for all containers in xTalk: variables, fields, buttons, images (and even URLs where we treat them as containers). Would the same apply to a new assignment operator? Consistency would say it does. x = 4 field myField = This is some text button myButton = line 1 to 4 of x image myImage = url binfile:myImage.jpg the selObj = somevalue Once we start seeing statements like these we basically have two languages being used at once when most of us have a hard time learning one. So my plea is Don't mess with the language without good reason. And I don't see one in this case.

mysql oddities
I've been using rev to link up to MySQL for a while but I've just changed my web space supplier and I can't connect to MySQL. I thought that this was their problem but it's stranger than that. If I use the database query builder then the connection is made and I can see the tables and fields and can query the database. When I try to do the same thing in my own stack - and those of other people who use MySQL - I get connection errors. What I'd really like to do is get inside the database query builder to find out what commands it is using to connect to my database. Alternatively, can someone provide some tips about the port variable in the revopendatabase function? I'm just putting the port number as a colon and number immediately after the host url and I'm sure this is right, eg :3337. Is there any other way to write it? Also, I don't want to use the database query manager all the time because I intend to distribute this as a standalone to users of the MySQL database.

Add it to Bugzilla
Hi all, List traffic increases each day. Many posts end in a bugzilla it (between 1 and 5 each day...) As if Bugzilla was the panacea :-) Overloading Bugzilla is not efficient for all of us and Runrev guys either. I have some experience with Rev and I found out many times that the nasty bug was in my code. So first, let us check carefully our code: isolating the problem in a brand new test stack is a good way (so many things can interfere). Let us try to reproduce the bug knowing the conditions with precision. Let us change the conditions to track the beast. If it turns out that's really a bug, then let us take list advice... And then, may be, it's worth to go to Bugzilla, check first if this bug is not yet in the database (with another approach) and describe the occurence with precision, the right words, samples of code, etc. :-) Second, as I told it lately in another post, different kinds of bugs have to be considered: Those which can affect standalones: they can be severe since they affect our end users (i.e; our professional ability/credibility). In this category, some ones come from the engine: we can't do anything except to go to bugzilla :-( Other ones can come from Transcript routines (as was the recent Answer Dialog bug with 2.6, revGoUrl in some conditions, etc.): many guys on this list pay attention to these ones and provide patchs or useful workarounds. Finally, there are bugs (or dysfunctions) which affect only the IDE behaviour: very irritating but only for us :-) They are less important than the first ones. So, let us learn to estimate what is worth to be bugzilled and how before running: it will be more useful for Runrev guys and all of us. Best Regards from Paris, Eric Chatonet.

Fast/slow code example (was: Re: compileIt for revolution?)
Hi Christian, Le 24 juin 05 à 10:21, Langers Christian a écrit : Could you, please, give us (newbies/intermediate scriptesr) some examples of fast/slow script code ? They would be too many :-) In fact, the problem is often more an architecture issue than a simple code issue. But here is one tiny trivial example among thousands to give you some clues: on CheckList repeat with i = 1 to the number of lines of fld List1 set the itemDel to tab put item 2 of line i of fld List1 cr after fld List2 end repeat end CheckList Main errors in the above 4 lines are: manipulate data directly from a field (a lot of work for the engine) use the repeat with i form slower than the repeat for each form (especially noticeable with long lists) force a screen redraw at each repetition (that's the must for slowing down) set the itemDel unnecessarily at each repetition The result with 1000 lines: more than 13 seconds... Better code: on CheckList local tList, tLine, tNewList - put fld List1 into tList set the itemDel to tab repeat for each line tLine in tList put item 2 of tLine cr after tNewList end repeat put tNewList into fld List2 end CheckList manipulate data into a variable use the repeat for each form use one screen redraw only set the itemDel only when needed The result with 1000 lines: less than 20 milliseconds! 650 times faster...

If I were to do it that way I would function equals theVar,theVal put theVal into theVar return theVar end equals then in the script equals(b,2) does affect 2 to b. Both seem to work. However it is still not infixing. So its not really what I'm looking for. Also earlier someone suggested you could use == for assignment. I don't think that is the case, but I am no expert in C. I thought that all languages other than basic use two different operators for affectation and comparison to avoid any confusion. Allowing == to operate assignments would be illogical. I'm not sure why I refer to affectation as affectation and not assignment. I speak French and German fluently, maybe that is why? __ Do You Yahoo!? Tired of spam? Yahoo!

TIP: New Image Checking Script v2
OK after the past comments received, here the latest script to scan all your opened stacks for existing images and thus avoid possible conflict or patterns or icons not showing up correctly. I added a template to list the images' locations too since that could be useful to find the conflicting images... ListImageNamelocations will thus list all locations of an image with a name in the long id of card form. I changed the way the string was searched in the image search loops so it's faster too. Which is faster is in or offset()0 The ImageIDExists and ImageNameExists are boolean functions and made for speed not for extensive search; for a listing of the container of the image name you might search use the ListImageNamelocations or make your own variations. It's as simple as it gets so you can extend with your own wrappers or within your scripts. Other possibilities, if you want to contribute back (those wrappers might be intersting for many different occasions - like listing images by name or id or both in a list and so on. Before you decide to script them, ask if i haven't dont so already, i might sooner or later. Also added 2 handlers to update the image list on a per-card or per-stack (with all the cards) into the image global database - this preventing a complete rescan. There's a force parameter to make sure you can resynch if you made extensive changes. For most cases the Force=ON should be ok and not felt.

Re: compileIt for revolution?
With all due respect, Jim, if you are trying to do even simple math on a large array of numbers (like computing a histogram of image data), Rev is simply too slow to use. It has nothing to do with data structures: it has to do with slow pCode trying to run tight loops. Jon Jim Bufalini wrote: Guess I'll add my two cents. I'm a newbie to Rev (Revolution) but worked over 25 years in Rev (Revelation), another similar, high-typed, extensible, flexible, run as you program, script language. It's an implementation of Pick on the PC. I was considered an expert. I also owned a company and employed programmers. I too, have heard these discussions hundreds of times, over the years. Speed of execution rarely relates to code, or the language, or whether it's compiled, or in pcode or whatever. It always has to do with data, whether the data is in arrays, or a database, or whatever object. Any language can add 2 to 2 instantly, regardless of the syntax. You don't get speed by changing languages, or writing lengthy workarounds, or complaining about your tools. You get speed by designing, in advance, the layout of your data. This requires straight thinking. 1. Know what you are setting out to accomplish before you type one character of code (what are your client's (your) goals?). 2. Layout and optimize the data you are going to access BEFORE writing any code. How are you indexing the data? Is it real indexing or organization? 3. Now write your code. If you find yourself writing spaghetti code, STOP, go back to step 1.

This whole discussion has been revealing and intriguing to me. My favorite programming language is Smalltalk. But before it was possible to create UIs for Smalltalk without writing code, I found it cumbersome. When a product called WindowBuilder came along, I felt like we'd achieved the ultimate development environment. In many ways, I still think that. Smalltalk had other problems, unfortunately, that made it great to code in, difficult to impossible to deploy. Then my second favorite language was Python. The GUI-building tools for Python are pathetic to non-existent. But the language is powerful and elegant and extends naturally. If the PythonCard project I was engaged in before I discovered Revolution had been on a fast track or complete, odds are I'd have never used Rev. Now I favor Transcript and RunRev. Building UIs is all but painless and 95% of what I want or need to do in creating apps is simple inside the elegance of Transcript. But Transcript isn't object- oriented. Two aphorisms came to mind as I read this entire thread again today. One is, No good programmer uses only one tool for everything.

Re: compileIt for Revolution?
I wasn't going to say this before, but I agree that XTalk has NOTHING to do with Pascal. The control structures are entirely different (no FOR, no WHILE, different CASE), there is no type checking, no variable scoping, no procedures. The quotes you provide only illustrate the point that some people who write books are clueless.

You might have heard of the maxim Fortiter in re , suaviter in modo. If not, look it up. In any event: think about it. Substantively, I stand by my story: xTalk is a scripting language which is clearly derived from Pascal. Don't take my word for it though; get a copy of think pascal (it's free) and look at its debugger and hypercards, its script formatter and hypercards. Or, just read wikipedia. HyperTalk scripts are fairly similar to written English, and use a logic structure similar to the Pascal programming language. http://en.wikipedia.org/wiki/HyperTalk HyperTalk is the scripting language of HyperCard and its clones. It is similar in syntax to Pascal, and includes enough object-like data structures and programming aids to make it a quite useful development environment (Allen 103). http://www.iath.virginia.edu/elab/hfl0133.html There's even an entire article on macTech Comparing HyperTalk to Pascal which says, Both Pascal and HyperTalk provide powerful if-then-else control structures with very similar syntax. The specification and calling of user defined functions in Pascal and HyperTalk is almost identical. http://www.mactech.com/articles/mactech/Vol.04/04.09/HyperTalk,Pascal/ Based on the comparisons presented above between Pascal and HyperTalk, it should be clear that HyperTalk is indeed a powerful language with many similarities to Pascal. I could keep looking, but I think I've made my point. __ Do You Yahoo!? Tired of spam? Yahoo!

Re: Rev won't start in Mac OS 10.3.9
Hi Bill... I tried running with extensions off, except the ones you

OTUtilityLib could not be found. At least Rev just didn't quit without a
trace. I did a search on my system folder and couldn't find it anywhere

This should result in better service for everyone all round, but does entail some minor inconvenience during the transfer. We will do everything we can to minimise disruption, but you should expect outages to the website, runrev email addresses, the store, customer support, bugzilla, and the discussion lists over the course of this coming weekend. These will not necessarily occur all at once, and we will restore them in priority order as quickly as possible. There could be up to a 24 hour hiatus in finding the website while our new server address propagates across the internet. Disruption should be confined to the period 10am on Saturday to 10am on Monday (UK time). Thank you for your patience during this essential transfer.

RE: compileIt for revolution?
Jon, My point exactly: a large array of numbers = data So is the photograph you are computing the histogram on. Would either of these change, if you switch languages? Hence, they are external to your language, or data. I write business application software, so I've never had to compute a histogram and admit I have no clue as to what's involved in that process. However, I have to believe that it is no different than someone saying we have over 200,000 lengthy depositions and need to quickly know any deposition where Jon said to Jim with all due respect in the second quarter of the year 2005 while discussing the topic of compilIT for revolution?. And, we don't want any false positives. If you try to brute force this and depend on your language, OS, and platform for speed of execution, you could be waiting minutes, hours or even days for the result. But, if you know the kind of data manipulation you will be doing in advance, you can parse, index, or otherwise reorganize the source data in such a way as to minimize large data sources or large arrays. Now, depending on how well you organized your data, whether your language is in pcode or machine compiled, results in only milliseconds of difference. Believe me, over 25 years of programming experience bears this out. Jim -Original Message- From: Jon [mailto:[EMAIL PROTECTED] Sent: Friday, June 24, 2005 1:27 AM To: [EMAIL PROTECTED]; How to use Revolution Subject: Re: compileIt for revolution? With all due respect, Jim, if you are trying to do even simple math on a large array of numbers (like computing a histogram of image data), Rev is simply too slow to use. It has nothing to do with data structures: it has to do with slow pCode trying to run tight loops. Jon Jim Bufalini wrote: Guess I'll add my two cents. I'm a newbie to Rev (Revolution) but worked over 25 years in Rev (Revelation), another similar, high-typed, extensible, flexible, run as you program, script language. It's an implementation of Pick on the PC. I was considered an expert. I also owned a company and employed programmers. I too, have heard these discussions hundreds of times, over the years. Speed of execution rarely relates to code, or the language, or whether it's compiled, or in pcode or whatever. It always has to do with data, whether the data is in arrays, or a database, or whatever object. Any language can add 2 to 2 instantly, regardless of the syntax. You don't get speed by changing languages, or writing lengthy workarounds, or complaining about your tools. You get speed by designing, in advance, the layout of your data. This requires straight thinking. 1. Know what you are setting out to accomplish before you type one character of code (what are your client's (your) goals?). 2. Layout and optimize the data you are going to access BEFORE writing any code. How are you indexing the data? Is it real indexing or organization? 3. Now write your code. If you find yourself writing spaghetti code, STOP, go back to step 1.

This whole discussion has been revealing and intriguing to me. My favorite programming language is Smalltalk. But before it was possible to create UIs for Smalltalk without writing code, I found it cumbersome. When a product called WindowBuilder came along, I felt like we'd achieved the ultimate development environment. In many ways, I still think that. Smalltalk had other problems, unfortunately, that made it great to code in, difficult to impossible to deploy. Then my second favorite language was Python. The GUI-building tools for Python are pathetic to non-existent. But the language is powerful and elegant and extends naturally. If the PythonCard project I was engaged in before I discovered Revolution had been on a fast track or complete, odds are I'd have never used Rev. Now I favor Transcript and RunRev. Building UIs is all but painless and 95% of what I want or need to do in creating apps is simple inside the elegance of Transcript. But Transcript isn't object- oriented. Two aphorisms came to mind as I read this entire thread again today. One is, No good programmer uses only one tool for everything. The other is, It's a poor workman who blames his tools. ~~ Dan Shafer, Revolution Consultant and Author http://www.shafermedia.com Get my book, Revolution: Software at the Speed of Thought From http://www.shafermedia.com/revolutionbooks.html ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution ___ use-revolution mailing list

If you don't print or use Appletalk then you won't need any of these
extensions. Also do not use Tiger as it breaks too many things in classic.
Even Tiger 10.4.1 which I also tested. If you already installed Tiger it is
impossible to uninstall unless you have a backup you can use Carbon Copy
Cloner to re-install from. The real solution is to re-write all your
Classic stuff in RunRev and not bother with Classic as I'm sure each new OSX
update will subtly break something else. Also keep a back-up copy of the
above extensions as OSX will corrupt them and then you will need to copy
over the back-up (this happens to me constantly).

Interfacing to externals. [offshoot from CompileIt for Revolution]
Although there may be changes possible that could reduce the need for externals, I believe there will always be good reasons to use externals. I think the current mechanism used by Rev to do interface to externals is missing an opportunity, and indeed is inelegant (or unaesthetic), because it forces the interface - and hence the calling Transcript code - to be different from what it would be if the function/handler were internal (pure Transcript) rather than external. [If I've missed something, and there is already such a mechanism, please tell me. I know you can retrieve such binary data from within the external, but as far as I can tell you cannot *pass* it to an external.] The mechanism used passes null-terminated strings (an array of them, for the parameters) and returns a null-terminated string (if it's a function). This precludes passing, or returning, binary data. So, in pure Transcript, I would create a function as follows: function manipulate pImageData -- do something to the image data, creating a new image in newImageData return newImageData end manipulate and call it as put the imagedata of img mine into myImage put manipulate(myImage) into newImage set the imagedata of img destination to newImage However, if manipulate was to be, or become, an external then you cannot provide that interface. You need to change it such the calling side looks like put the imagedata of img mine into myImage manipulate myImage, newImage set the imagedata of img destination to newImage (or a variant of that. You could keep it as a function - but since its result can't be the binary data, there's no reason to do so). Alternatively, I might be willing to overwrite the original data (and save the time for replicating it), and then do on manipulateInPlace @pImageData - change it end manipulateInPlace Then it would be called as manipulateInPlace myImage and again if it had to be an external, the interface would need to be manipulateInPlace myImage You can't pass binary data because the parameters appear on the C side aschar *args[] (and similarly the return value is a null-terminated string). If that could be changed to pass an array of MCStrings (i.e. MCstring[]) then, because they'd be length-specified, there would be no problem with binary data. Similar change for the return value from a function. Even if this does seem like a desirable change, is it feasible ? I think it should be. Obviously it wouldn't be possible to just change because it would be incompatible. But the Xtable[] used to define the entry points already contains a type, currently one of XFUNCTION, XCOMMAND or XNONE. The set of types could be extended to include, say, XBINFUNCTION and XBINCOMMAND which determine that the paramters and, where applicable, return value are MCStrings rather than char *s. Therefore the engine would know which parameter passing mechanism is in use, and behave accordingly. The primary benefit is that it alows the interface to be more Transcript-like - no (regular) pure-Transcript function would expect to be passed a string containing the name of a variable in preference to passing the variable itself. The secondary benefit is that you could initially write a Transcript version of the function, and later replace it by an external versino of the same function without revisiting every place it is used to change the calling convention. There is a tertiary benefit of minor speed improvement from avoiding the callback to retrieve (and set) binary parameters (and results), but I don't think that's significant, and it would not be a reason to suggest this change. I don't see any major drawback. There is a minor drawback, in that it is an additional mechanism to be learnt by anyone starting to write externals, and to be considered each time you design an external's interface.

Dan, Perhaps we are in perfect agreement, just expressing it differently... I could not argue with the way you have expressed it here. Dennis On Jun 24, 2005, at 1:09 AM, Dan Shafer wrote: Dennis.

Any experience with Expect
Hello all, I was talking to a friend the other day and discovered that he does a lot of hardware testing (regression testing, feature testing etc). Since this is a tedious task most people have been using a program called Expect. Homepage is http://expect.nist.gov/ Tcl/Tk has been used a the user interface. 1. I was wondering if Rev would not be a good alternative to this in native form? 2.

First.. thank you for your intelligent reply to my:
okay.. back into my hole...
Yes, Please stay there.
It is good to so easily learn so much of the people we correspond
with. I'm not surprised that I touched a nerve but I am surprised
at the scream ... sorry ;-{ )
My apologies, I was a bit over the top yesterday in my reply. Yes, I
want to make intelligent discussion not hyperbole. We all have our
bad days. I felt like I was being ambushed, and that you were going
to retreat out of the conversation.
Second..
var := x
var == x
var = x --this is a bit tougher

var gets x
are all the same thing!
Well.. they are close. They all may have the same result at a
machine code level... (although I believe var == x resolves to TRUE
if var and x are the same (false otherwise).. and usually the same
for (var = x) if it is parentheses? )
Oops, but at least you knew what I meant . APL left arrow was
supposed to go into that spot.
but the discussion is not about values of variables or what the
machine does... or at least my contribution wasn't. It seemed to
me, the discussion was about consistency in a language and the
inclusion of semantically different operators in addition to those
that are inherently ones. Seems like you didn't understand rather
than me.
I did understand you, and I can accept that a var gets x is not xTalk
as long as var := x is also not xTalk. That was my point. The gets
term was my suggestion as being more xTalk than := and could be
related semantically to the get command which is also left assignment.
Third...
You say one is a good construct and another is an inconsistent
construct! That makes your argument inconsistent.
Maybe reread my post? I don't see in my message where I said any of
those was a good construct for an xTalk. I said put x into var
was a good construct for an xTalk language because it is consistent
with the concept of telling the object what It should do as
opposed to a variable being assigned something... It may seem a
trivial point but it is at the root of the discussion...
I personally have nothing against := and = for variable
assignment --I took to be your acceptance as good.
Or perhaps the point is that if all of the above are the same but
are non-xTalk friendly conceptually, is it appropriate for us to
worry about whether Transcript includes any of them Of course
you left the put x into var out of the list even though I would
assume that from your point of view it is also the same thing
So why did you leave it off? it appears to be the only one that is
100% consistent with the xTalk construct. Could it be you agree
with me at some level?
Put x into var is a right assignment command. Not the same thing.
The whole thread is about a left assignment operator and the desire
to conceptually have a left assignment as an extension of the
language. And, yes, I do agree with you at some level, just not the
way you argued for your point. I tend to take an argument to the
extreme opposite position in order to discover the core issue. It
makes everyone (including myself) think more clearly. I also test my
code with values of -infinity, -1,0,1,+infinity,empty. I find
the flaws faster with the edge conditions.
Finally...
You just don't get it ;-)
I can't say I can get it into your head, though I can put it into
your head.
Perhaps Jim gets it now.
... telling someone their argument is inconsistent or that they
don't get it when it appears you maybe didn't actually listen to/
read what they were saying does little to build your credibility.
Following the same with a condescending cute smiley does not help.
This list is a great place for constructive discussion and it
should stay that way. Keep your personal comments to yourself.. and
I'll be lighter on the ...some renegade variable is off filling
itself with data... comments.
I guess I was a bit too obscure. The ;-) was the clue that the
statements were an example of get, put, gets syntax and a
lighthearted jab not meant to be taken too literally:
You just don't get it, because get it is a no op.
I can't say I can get it into your head, because get...into is
bad syntax mixing left and right assignment, showing the difference
between get and put.
Perhaps Jim gets it now... new syntax of left assignment that is
English like syntax.
However, from the various replies to my gets suggestion, I don't
think gets is the best choice for a left assignment for Transcript
because of the lack of imperative. In BASIC the LET was the
imperative to LET var=x. The LET was redundant from a parsing point
of view, so eventually fell away. So in Transcript left assignment
might be better stated using the familiar syntax: set var to x
The get command becomes the shortcut

you need a real algotithm. The within function only works on rects only AFAIK. But the graphic will only detect a mouseup if you click on its graphic, not the rect - so somehow, it's calculated...

RE: is within ... polygon shape?
Perhaps I am confused... But if you are going to hide the top object, then put the mouse over the polygon - then all you would need to do is use the mousecontrol function. If the mouseControl is the polygon in question - then you've got it. However, this does not tell you if any point of the top object is over the polygon. This would only tell you if the point at which you place the mouse is over the polygon. If pLoc is in the middle of the top object, but only the edge of the top object is over the polygon, then this test would miss the overlap. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Steve Bonham Sent: Friday, June 24, 2005 10:55 AM To: How to use Revolution Subject: Re: is within ... polygon shape?

advice
I just need some advice and opinions on this one. I'm working on creating a little backup / WinZip-like application (mostly just for my own use, but we'll see). I would like to store backed up files into custom properties of a stack, so that everything is contained in one easy-to-use file, much like a WinZip or Stuffit archive. Here's my question. I'm debating on whether to compress the files first, and then place them in the custom props, or to put them in uncompressed, and then compress the entire stack file all at once. Is there any benefit doing it one way over the other? I would think it would be faster to compress/decompress one file as opposed to many, but it would also mean that upon restoring the archive, I would need to decompress that archive and save it to a temporary stack file, then delete that temp file when the process is complete. Or am I wrong about that? Anyway, this is just kind of a design issue, and I'm wondering what the rest of you would do. Which way would be the most efficient?

RE: is within ... polygon shape?
Yes, but the mathematical testing for such a thing is not easy... I mean, if it was a simple shape, with a simple formula to define the shape, then it probably would not be so hard. But, with an irregular polygon, you have to do something like this: Outer repeat loop (goes through every visible point in the bottom shape) Put the point to be tested into tPoint1 Inner repeat loop (goes through every visible point in the top shape) Put the point to be tested into tPoint2 If tPoint2 = tPoint1 then Return true Exit this function End if End inner repeat loop End outer repeat loop Doing that in transcript would be kind of slow. I imagine there must be faster algorithms, but they will all require tons of comparisons. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of MisterX Sent: Friday, June 24, 2005 11:08 AM To: 'How to use Revolution' Subject: RE: is within ... polygon shape? if it's all white, then what? ;) nothing beats mathematics ;) cheers 1/X -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Steve Bonham Sent: Friday, June 24, 2005 16:55 To: How to use Revolution Subject: Re: is within ... polygon shape?

Re: Any experience with Expect
As far as I can tell Expect in it's native form is simply a command line. Tcl/Tk was used to create a GUI enviroment for it. So Rev (which is a far better GUI enviroment ) could be used to develop a more custom interface for particular users. So if you ignore the addition of Tcl/Tk you have a command line package which could be accessed with Rev through the shell or possibly make Expect a Rev external.

I don't see where a GUI wrapper would help in either creating scripts or running them. You'd still have to write the scripts and then hand them off to Tcl/Tk for execution. Possibly in archiving and retrieving regression tests, but rev seems a bit of overkill in that department. -- -Mark Wieder [EMAIL PROTECTED] ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

AFAIK? Is this pronounced like the duck says it in the insurance commercial? Seriously, what is AFAIK? S you need a real algotithm. The within function only works on rects only AFAIK. But the graphic will only detect a mouseup if you click on its graphic, not the rect - so somehow, it's calculated... There's plenty of them algorithms on the net. search region intersection and/or polygon intersection fun stuff... im sure there's a Gauss or old greek technique for this! or... the xtalk way you can simulate a click at any point and if the target is the card or not the graphic, then you got your intersection logic running. i'll see what i can dig up tonite... interesting problem: is point in *space(f) of f(i) where i is any graphic def. oh and, new bugz 2934 found!

RE: is within ... polygon shape?
How about this technique... This would work as long as the two objects are not the exact same color. Step one: Put object 1 on top of object 2 Take a snapshot of the rect that contains both objects Put the imagedata for that snapshot into tImageData1 Step two: Put object 2 on top of object 1 Take a snapshot of the rect that contains both objects Put the imagedata for that snapshot into tImageData2 If tImageData1 tImageData2 then return true Basically, the idea is that, as long as the visible portions do not overlap, the image of the rect that contains both objects will be the same, regardless of which is on top. If the image of that rect changes when the Z order changes, then they must overlap. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Lynch, Jonathan Sent: Friday, June 24, 2005 11:54 AM To: How to use Revolution Subject: RE: is within ... polygon shape?

Re: the := operator (affectation
Dennis,
My apologies, I was a bit over the top yesterday in my reply.
Thanks... and I was a wee tad over in my response...
I guess I was a bit too obscure. The ;-) was the clue that the
statements were an example of get, put, gets syntax and a
lighthearted jab not meant to be taken too literally:
You just don't get it, because get it is a no op.
I can't say I can get it into your head, because get...into is
bad syntax mixing left and right assignment, showing the difference
between get and put.
Perhaps Jim gets it now... new syntax of left assignment that is
English like syntax.
What a difference a few quotes make. I can hear your voice now and
understand where you were headed. Fine example of dangers of
interpreting email too literally which I am prone to do when
tired. What appeared to be sarcastic and cynical and rude was in fact
clever example...
So in Transcript left assignment might be better stated using the
familiar syntax: set var to x
The get command becomes the shortcut equivelent of: set it to
So you see Jim, now I get it!
Or,,, get is a shortcut for put the propX into it... the set - put
difference still rears its head
I have always been bothered by the left right reversal between
setting parameters (just another type of container), and putting
into variables. I have mistyped setting the parameter many times
using the form: put x into the parameter of y. The syntax is not
ambiguous as far as I can tell. Perhaps both set and put syntaxes
should be regularized to allow either, and relegate parameters to
the ordinary family of containers. At least allow the setting of
variables even if putting into parameters is kept exclusive.
Comments?
When phrased this way, the left - right assignment question becomes
one, not of :=, =, etc. but rather Why can't I set a
variable to x? and why can't I put something into a property? ..
that's simple enough for even me to get ;-{)
Off the top of my head there are significant differences between
variables and properties: persistence (properties stay there when you
shut down), scope (you can access any property from anywhere whereas
variables must be explicitly defined as global and then are available
only if the stack is running and has assigned them a value) and
messaging (objects can respond to a change in their properties
(setProp getProp)). Is that enough to justify a syntax change for
addressing them H?
It may be that last item that is key.
Set sends a message to an object the one with the property...
and that object can react to that message appropriately with setProp/
getProp
Put doesn't send a message anywhere... well.. execpt for the fact
that the object responds to a put the propX into var anyway with a
call to getProp
So why couldn't an object respond to a put var into the propX with
the setProp structure... it could..
So maybe it doesn't matter? Am I coming around to a different
perspective?
Of course.. none of this has to anything to do with assignment
operators...

RE: Fast/slow code example (was: Re: compileIt for revolution?)
Eric, For someone moving from other languages (like I am) to Transcript, I believe three of the four errors you point out in your example should be obvious and the same in all languages. Those are: 1. Repeatedly accessing the same data structure (field) instead of first putting it into a variable. 2. Repeatedly updating the screen on a background process. 3. Repeatedly setting a property that only needs to be set once. However, the repeat with i = form being slower than the repeat for each was news to me! There is nothing in the documentation, that I can find, that addresses the most efficient way, from the perspective of the engine, to write a control structure. Apparently, this is particularly true of the repeat structure. Is it also true for say the if..then structure? Is it more efficient to put your conditions into variables and then use the variables as conditions of the if...then? These are the kinds of things a newbie (like myself) would greatly appreciate being documented. This is to say, if there are two or more ways to write the same statement (as with the repeat example), then if someone knows one works faster than the rest, because of their knowledge of the inner workings of the engine, then this would be valuable to document or post. This might cut down the 300 pages. :) Jim -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Eric Chatonet Sent: Thursday, June 23, 2005 11:02 PM To: How to use Revolution Subject: Fast/slow code example (was: Re: compileIt for revolution?)

set defaultFolder to non-existent folder behavior
Hi all, here is an interesting one I thought I'd pass along to see if anyone has encountered this before. In the documentation for defaultFolder it says that if you set the defaultFolder to a folder that can't be opened it returns can't open directory. So i have some code that mounts a volume from a networked computer to move some files across the network. I created a function to check if the network computer is, in fact, mounted. The function works correctly when the drive is mounted in that result () is empty. Now, to test my code, I unmounted the volume through the Finder(eject) and disconnected the network cable from the computer. But when I ran the code a second time, result() still came back empty. That is, in the second attempt I set the defaultFolder to /Volumes/MountedDrive/Folder/ when it should not be possible, because there wasn't even a physical connection. Whats interesting, is that i opened the console and listed the drives available in /Volumes/ and sure enough MountedDrive was listed despite the fact that it wasn't listed in the Finder. I even rebooted with no network cable and MountedDrive still appeared in / Volumes/. So I tried one last thing, if the defaultFolder was truly set to MountedFolder then my file moving code should work, right? Wrong. That code threw an error and failed as you would expect since there was no connection! Does anyone know why this is? Is there some period of time that old connections are retained in a lookup table b4 being removed? I'd really like a solid mechanism to ensure that the drive is mounted, and the above does not seem to provide that.

On Jun 24, 2005, at 12:42 PM, Jim Bufalini wrote: However, the repeat with i = form being slower than the repeat for each was news to me! Upon reflection, you might have wondered about that. The key is that the first uses 'line i of x' in the loop. The length of time to get this value increases with i. Normally, values are simply sequences of characters and values with multiple lines are simply values that contain some line-delimiter characters (coded the same as ASCII LF). Though it is possible that some internal optimization breaks these up into structured data or a line-index table is cached, it is reasonable to suspect that this is not the case. If there is no optimization to finding line n, then all characters form the start of the string to line n must be searched. It is possible that some compiler optimization would look for line n in loops and convert, but our first assumption should be that it probably doesn't. We might assume that 'for each' does not have this limitation. We might assume that 'for each' keeps one or more hidden character indexes in managing the loop. Given such suspicions we might try some timing or ask on the list. This does not currently apply to characters; 'char n of s' executes in constant time. Even so... We all are sometimes surprised by things that should jump out. I am. It should be mentioned in the docs. (And probably is and I don't know where.)

It only has assignment commands. Introducing an assignment

the only reasonable option of a left assignment command. Set and put
are already defined in a a way that the compiler could translate them
to the appropriate low level codes. Messages would be sent when
accessing properties, and not for variables. If set must be the
purview of properties only, then we would need a different word, but
I can' t think of a good one off hand --nor a good reason to have one.

There is in that desire a strong implication of adding features to the language that I believe will ultimately corrupt it to the point of not being accessible to mere mortals. It's what I call the Javazation of Transcript. If you have a need for something in a program that Transcript simply can't do and if the right way to solve that problem is with an external, then it seems to me you should be willing to move outside the boundaries of the language to do that thing, whatever it is. (These multi-dimensional array manipulations, e.g., can apparently not be done satisfactorily in Transcript.) I'm *always* going to come down on the side of keeping the language as simple as possible. In my opinion, it is already too burdened with baggage that is of use to a tiny fraction of its users in order to accommodate a few people with specific programming needs. As it becomes more complex -- even if those complexities are posited as optional alternatives -- it becomes more and more impenetrable to those who do not have a computer science background or formal computer training.

It's a functional starting point for developing external using the free compiler named Dev-C++ (Bloodshed). The first, i think. When you get sucess compiling one external with Dev C++, then you could try to compile the source code of other externals provided by developers in this list. After that, if you have sucess, it's all up to you and your time for experiments... ;-) al Visit my site: http://www.geocities.com/capellan2000/ Yahoo! Sports Rekindle the Rivalries.
