[REBOL] Newbie: Help with image buttons (View)
Hi, I'm trying to make a cell phone demo for the computer which involves having the button on the phones to become active. For example... I want the demo to be able to have clickable 'numbers' to dial a phone number, and a clickable 'send' button to emulate placing a call. I run into a problem because, the phone's buttons are not rectangular in shape. I made the phone's buttons into separate images and overlayed them onto the main image of the phone, but the REBOL buttons are rectangular in shape, and have a shadow/border. Is there a way either to: 1) Make the buttons in REBOL/VIEW, have no border and no effect when the mouse clicks on it? (Buttons usually sink when clicked on). 2) Make a coordinate system over the image of the phone and detecting mouse clicks over that coordinate, particularily over buttons? Thanks!

You'd also have to take into account that you can pick more than one item in a list if Ctrl is used when clicking - picked will contain a block of strings then, not just a string. (For this reason I'd guess the index to the picked item isn't stored anywhere in text-list, but I may be wrong about that.) If you can have duplicates in the list, using same? to check if what's found matches what's picked might be one way to test it. (Find finds series that are equal, but they may not be the same series.) If they're not the same, then repeat the find from where the match was found until they do.

[REBOL] Re: Dialects - Bane or Blessing? (was: Teaching Rebol)
Hi all, I think dialects are something we're going to learn a lot more about as we start to really learn how to create and apply them. Since I think dialects are so important, I'd love to hear some other viewpoints about their pros and cons. This isn't a rant, or an attack on your view, but your note inspired me to think a bit and, now, ask more folks here to think a bit and share their thoughts. Gregg great post. I agree with it all, although I didn't quite understand what you meant by In a good dialect, there shouldn't be any *extra* vocabulary or syntax. Just the dialect. Last night I spent quite a while making a simple dialect more sophisticated. It sort of evolved as I thought up interesting extra functionality to add. But even while the functionality grows, the dialect grammar does not necessarily grow as fast. A nice property. Leverage. I'm evolving my dialect because I'm not an experienced grammar designer and I find that choosing how to the structure of the grammar to be really hard. But it is good experience. Thinking through these decisions makes me appreciate just how much VID can be seen as a work of art. It also makes me realise that having a cookbook for writing dialects in REBOL would be really great. I've tried searching the internet for information on how to design a good grammar and to me it seems as scarce as hen's teeth. Yes there's plenty on how to parse one or compile one but not on how to make one conform to your goals. It might also be nice to a sort of dialect framework - e.g the structure of VID could be used in multiple domains so is it possible to make it resuable as a quick start for someone building a new dialect? I guess this situation of lack of grammar design information comes about because designing a language is not ordinarily considered an developer activity - more a software tools manufacturing activity - or maybe I was just looking in the wrong place. Maybe REBOL will alter this situation. In terms of example, at least some of the XML languages can be used to reflect on. I mean XML is all about adding meta information to your base information. REBOL dialects are too. So there can be a creative mixing of ideas there. For me though I think the REBOL dialect approach is easier to explore because the building blocks so naturally follow and are indistinct from the supporting language. In terms of internal REBOL dialects my favourite is VID naturally enough. PARSE. CONTEXT, SECURE, COMPOSE, BUILD-TAG and rebsite index.r files provide food for thought too. Here are some external REBOL dialects I can name straight off: Ingo Hohmann: TUI Dialect (Produce ASCII sequences) Andrew Martin: -he just posted his list- Joel Neely: generate-data (Generate test data from production rules) David Oliva: Flash (SWF) Project Gabriele Santilli: PDF-maker Frank Sievertsen: lego (Lego-Cybermaster Robot control protocol), irc-protocol, reb-log (Prolog dialect) My main concern about Dialects is that the new extra vocabulary/syntax to learn and lack of indication. How much indication a dialect provides will depend on the dialect. The PARSE dialect provides quite a bit of indication I think, which is valuable in that context. Defining a grammar isn't the place to have lots of ambiguity. :) I guess it depends on requirements. Its a hunch, but I think that if a dialect is going to be stable and the outcomes change not much then perhaps vocabularies / grammar can be minimal. But if the dialect has to grow over time without breaking older messages then you might need to build in some expansion flexibility or apparent redundancy. VID is amazingly extendable - even to the point that a VID style can be designed to interpret the input given to it as a special dialect in itself (within some limits of course). A dialect within a dialect. Regards, Brett. -- To unsubscribe from this list, please send an email to [EMAIL PROTECTED] with unsubscribe in the subject, without the quotes.

Andrew wrote: I don't think it's possible to get syntax hints for Rebol, unless one tries to execute the code. A Rebol IDE could show that a word refers to a function that takes X arguments of Y type/s. That's a useful hint, but that fails if the script (or a related script) replaces the value for that word when executed! :) It will also fail when looking at a word used in a dialect. ok.. RIDE ideas I donlt quite undetand why not - what does 'help do? REBOL interpreter is running so it knows as soon as it sees a white space that a word has been entered. It can do several things right then: - lookup the word indicate to the use, perhaps highlight the word in special color. [RIDE user prefs can redefine all this] test if it's a - core word - word defined in this session show so - word defined by import show so When a word is redefined that is useful to know too, even if the RIDE can't tell you at that moment what it is exactly. Just as it knwos about white spaces it knows about words ending in : I find at the shell when testing, I face confusion often if a word has a value, for example is holdigg on to 'old' values. For exactly the same reasons one needs to invoke the someword: copy [] idiom inside functions. When one loads an external script in the shell with 'do there are a load of fucntions defined there. The first helpful a new RIDE could do is tell you what functions are named. source help reveals a word 'dump-obj source 'dump-obj reveals 3 functions 'clip-str and 'form-val, 'form-pad Perphaps for system words it is not so relevant. But for externasl user scripts I think it woudl be very helpful. Once can al;ways lok ath source, but the issue is what kinds of dynamic helps are good. importinga script adn immediately getting a remionded of teh fucntion name swuodl be very useful. Proabbly in a parallel window so one does not break the flow of the actual session. I don't knwo if what i sugest is very eays or terribly hard. For example, in my Wiki script, I use 'form, with two different meanings. One is Rebol's usual 'form, the other is my ML dialect 'form that means create a HTML form with the following block! value. Similarly with 'head as well, one is Rebol's usual 'head, the other 'head means create a head section in HTML from the following block. so would'nt that be good to know ? Looking at a small section of my Wiki script, one could be easily confused! It's not until one sees the entire context that it makes sense. This seems to me to be a force that encourages me to keep scripts short and to have powerful words. Yes the art of REBOL must be to keep it short with well crafted words. Dialects presumably can help do that. But there must be a better way to indicate when one is stepping in or out of a dialect? ./Jason -- To unsubscribe from this list, please send an email to [EMAIL PROTECTED] with unsubscribe in the subject, without the quotes.

Hi Tim Despite the comments about documentation I think that rebol's help function is very accomodating for a new programming student. (and BTW I am also teaching python in a similar fashion) just try typing help split at the python prompt and see what you get. Yes that was precisely the initial point I made to Python Edu-Sig. They tried to show me sophisticated Python help is. And of course it is. My point was how direct and freindly rebol's help is, largely becuae it bundles a search function. I'd like to hear more about your Rebol teaching experiences... What age? What kind of stuff you do? ..students reactions. Do they use their programs together? What probelms do they have? Is this their first prgarmmnig experience? What is easy? What is hard? What sort of materials you'd like to see to help your efforts? But seriously, rebol is a very good first programming language. The absense of systems calls in rebol/core is a good thing.

[REBOL] Re: Cross Platform? Then what about Mac OS X?
- Original Message - From: Rod Gaither [EMAIL PROTECTED] Hope RT gets the work done on OS X updates sooner rather than later as I really need Core and I miss View and IOS/Express. I wonder if Core for BSD could be ported quickly to OS X? My understanding is that a lot of BSD stuff recompiles relatively easily under OS X. Lack of REBOL on OS X is one of the reasons holding me back from switching. Mostly I do a lot of Java coding, and I understand that OS X has good support for that (but my favorite IDE, Eclipse isn't there yet). And I write REBOL scripts to auto generate Java code pretty frequently; copy and paste a database table definition from MS-SQL (or any db) to a text file. Process it with a REBOL script to create class member attributes, getters/setters, and insert/update methods... Crude, but handy. Someday I'll just write a Java based meta-data inspector that can autogenerate the Java code for me. But, given the mixed JDBC support out there, I'm not sure I'm willing to trust that. It's only now with the JDBC 3.0 spec (where the drivers are, who knows?) that you can get the autogenerated ID of a just inserted record w/o using a transaction - something ADO and ODBC have been doing for years... Plus I use REBOL scripts to keep tabs on bunches of web sites, and to do web crawls and misc stuff. It's my prototyping language of choice. Proof of concepts are pretty easy to do in it, as you're not wrestling with intimate details in some cases. Still working on a REBOL implementation of the Gnutella protocol - I can advertise that I'm on the network, get back the Gnutella OK response, etc. so that's progress. With View/Pro I'm planning to use the Gnutella protocol to allow for secure sharing of virtual information... It's an odd project.

If that's the behaviour you want, just uses images instead of buttons. ie... rebol [] ; Create two images... img-1: to-image layout [backdrop pink text Image 1] img-2: to-image layout [backdrop yellow text Image 2] view layout [ output: field Click on images image img-1 [output/text: Image 1 show output] image img-2 [output/text: Image 2 show output] ] Other styles such as images can have a block which will be evaluated when the style is clicked on - it's not just the obvious ones like buttons that you can do this with. Hope that answers your question. 2) Make a coordinate system over the image of the phone and detecting mouse clicks over that coordinate, particularily over buttons? Thanks!

[REBOL] Re: Cross Platform? Then what about Mac OS X?
Hope RT gets the work done on OS X updates sooner rather than later as I really need Core and I miss View and IOS/Express. I wonder if Core for BSD could be ported quickly to OS X? My understanding is that a lot of BSD stuff recompiles relatively easily under OS X. Lack of REBOL on OS X is one of the reasons holding me back from switching. Core for Mac OS X was/is working with versions prior to Jaguar. Something small (I hope) broke with the 10.2 release of OS X. RT is aware of this and is looking at the issue but no word on when a fix will be available yet. Some work was also done on View on OS X (betas I think) - enough for RT to say they had some issues, including performance, that needed to be addressed before it was an acceptable port. Mostly I do a lot of Java coding, and I understand that OS X has good support for that (but my favorite IDE, Eclipse isn't there yet). And I I'm not a Java programmer but the little bit of poking around with it on OS X I've done supports that assumption. I'm using ArgoUML and jEdit with no issues and the Java integration with the Apple tools (Project/Interface Builder) is quite impressive. FWIW, Rod.

[REBOL] bitset help
I do not understand how can be used all this new stuff from the new betas. Can
someone make an useful example to me? I knows only how to use bitset in parse
rule for char, but this seems something different.
These are the RT docs:
2.3. New Bitset Functions: CLEAR, LENGTH?, EMPTY?
Three new functions (actions) have been added to bitsets:
The CLEAR function quickly clears all bits to zero.
The LENGTH? function returns the number of bits in the bitset (always multiple
of 8).
The EMPTY? function returns TRUE if any bit is set, otherwise it returns
FALSE. (Note that EMPTY? is the same function as TAIL?; therefore, TAIL? also
returns the same results, but the word has no meaning for bitsets.)
Bitsets are used as high performance logic arrays for character sets and
hashes.
Examples:
items: make bitset! 40
== make bitset! #{00}
length? items
== 40

Mostly I do a lot of Java coding, and I understand that OS X has good
support for that (but my favorite IDE, Eclipse isn't there yet). And I
write REBOL scripts to auto generate Java code pretty frequently; copy and
paste a database table definition from MS-SQL (or any db) to a text file.
Process it with a REBOL script to create class member attributes,
getters/setters, and insert/update methods... Crude, but handy. Someday
I'll just write a Java based meta-data inspector that can autogenerate the
Java code for me. But, given the mixed JDBC support out there, I'm not sure
I'm willing to trust that. It's only now with the JDBC 3.0 spec (where the
drivers are, who knows?) that you can get the autogenerated ID of a just
inserted record w/o using a transaction - something ADO and ODBC have been
doing for years...
Plus I use REBOL scripts to keep tabs on bunches of web sites, and to do web
crawls and misc stuff. It's my prototyping language of choice. Proof of
concepts are pretty easy to do in it, as you're not wrestling with intimate
details in some cases. Still working on a REBOL implementation of the
Gnutella protocol - I can advertise that I'm on the network, get back the
Gnutella OK response, etc. so that's progress. With View/Pro I'm planning
to use the Gnutella protocol to allow for secure sharing of virtual
information... It's an odd project.
Anyhow, that's quite a ramble off of the original OS X inquiry.

Hello Jason: * Jason Cunliffe [EMAIL PROTECTED] [020926 03:59]: Hi Tim Despite the comments about documentation I think that rebol's help function is very accomodating for a new programming student. (and BTW I am also teaching python in a similar fashion) just try typing help split at the python prompt and see what you get. Yes that was precisely the initial point I made to Python Edu-Sig. They tried to show me sophisticated Python help is. And of course it is. My point was how direct and freindly rebol's help is, largely becuae it bundles a search function. I'd like to hear more about your Rebol teaching experiences... What age? Eighth grade through senior. What kind of stuff you do? Intro basics, but finishes with ftp email and cgi ..students reactions. Completion is a problem... Do they use their programs together? No. Not so far What probelms do they have? Did I say that this is an online class? Anyway, that's really the main obstacle, how to proctor a motivate without physical presense. Is this their first prgarmmnig experience? It is designed as a first programming class, but some students have had html, a little C++ What is easy? Teaching the class no commuting :-) What is hard? Motivating them. What sort of materials you'd like to see to help your efforts? I've considered a couple of things: 1)A tutor program like TCL uses. 2)Some simple chat bot routines But they are simple add-ons. The main issues really aren't specific to rebol. They are a factor of what is (to us here) a new medium. But seriously, rebol is a very good first programming language. The absense of systems calls in rebol/core is a good thing. I don't have to have the student's parents sign one of those If you broke it with your program it ain't our fault kind of contract/disclaimers, as we are doing with python, perl and C. Thanks.

It has the wonderful and rather unique ability to execute code with a single mouse click, right in the middle of text. It's an incredibly persuasive demo of Rebol itself. Two problems I see in Easy-Vid based solution is that it is not web friendly and enabling.disabling so that needs to be managed. Hi Jason, VidWiki uses some of the easy vid code. The vidwiki client views dynamically (CGI) generated layouts, and the layouts can contain instructions to view layouts within the layouts. I did manage to convert several of the RT Howtos to this format with some modifications. But there is a limitation as to what you can do, and it doesn't scale well for larger pages.

Thankyou all for your thoughts so far re Rebol on Mac OS X it was gratifying to read such a broad and enthusiastic response. Although it appears to me that Rebol for OS X is definitely coming from RT [some time], I believe that our voices in unison can only help maintain the urgency and our spot in what has to be a very long development list. [If I only had the money.] Rods comment... Some work was also done on View on OS X (betas I think) - enough for RT to say they had some issues, including performance, that needed to be addressed before it was an acceptable port. was interesting, I personally would be more than happy to run a slow flaky /View beta rather than the nothing available at the moment. [Anecdotal evidence from this list suggests that Rebol Beta's are often better than some other peoples released code!] Just a thought, but Maybe RT could make /View beta for Mac OS X available on a personal request basis?

I felt (and was supported by the teachers of record) and there was enough eye candy around and that it was better to start them out in a way that would get them started in focusing on the small details that really are what makes programming work.

[REBOL] XSLT and folding code viewer
A nice developing example of using XSLT to generate 'folding' code docuemntation on-line is at: http://www.jserv.com/jk_orr/xml/driveinfoleo.htm The styling is raw still. But I think this is still an impressive example of how a functional language processor can take a complex trees structure and render it to XML/HTML In this case its XSLT converting a Leo file. Could be REBOL converting a REBOL tree also.. Jo Orr, who developed the above, made some interesting comments today about XSLT as a functional language. Naturally it also reinforces the role Rebol can play in this type of work. quote http://sourceforge.net/forum/message.php?msg_id=1694277 You can see from some of these samples included with Screenbook Maker BTW, that using XSLT to transform XML is far simpler and more elegant than any non-functional language solution. Another useful functional language is SQL. Not many would argue that SQL should be replaced with e.g. Python. So I wouldn't write XSLT off as a fad even if you are a Python wizard. The XSLT file I uploaded is unfortunately not an example of elegance, in fact I hardly understand it myself. But it *is* a lot shorter than it would be in a non-functional language. If we can get a nice package of XSLT stylesheets written, Leo could become a tool for creating outline format websites. /quote He has a page of developing Leo/XSLT experiments: http://www.jserv.com/jk_orr/xml/leo.htm ./Jason -- To unsubscribe from this list, please send an email to [EMAIL PROTECTED] with unsubscribe in the subject, without the quotes.

Hi Romano, I do not understand how can be used all this new stuff from the new betas. Can someone make an useful example to me?

Bitsets can be very handy if you have a really large number of boolean flags to keep track of and want to use minimal space and processing power (in general). The idea, of course, is that each flag only takes one bit, which means you can store boatloads of them in little memory when compared to, say, a normal boolean/logic! value that probably uses 32 bits (or more in the future :).
