[REBOL] virus-ip-scan
Hi, I build small but usefull script for my own purpose to allow me to scan network for possibly infected computers. It is new/rewritten version of my old script, which contained IP adresses hardcoded. Now they are abstracted. I have also one question, hopefully answered by Romano or Gabriele, but I would not mind answer by anyone else ... - what I have removed from script was request to dns://ip-here, because it lasted too long. So I only ask for computer-name via dns:// if possible virus is found. I know there is async dns possibility via dns:///, but I don't know how should I track it, so - it does not try to communicate with opened port - it only tries to open tcp port, and if successfull, it regards such machine as being infected - it does only tcp check, I was lazy to abstract i further and scan for UDP opened ports if any virus uses them, but I could add it :-) - don't set timeout too low. I tried with 0.1, so hopefully on local network it is ok, but you simply risk that if answer is not fast enough, it will time-out and in fact such machine could be infected ... - now for ranges of IP adresses: block of four integers or subblocks. Examples: 172 25 7 [0 255] ; scan all range on 172.25.7 network 172 25 7 [20 40 61 61 128 200] ; scans only 20 - 40, 61, 128-200 ranges on 172.25.7 network 172 25 [7 10] [0 255] ; scans 172.25.7-10 networks, from 0-255 [0 255] [0 255] [0 255] [0 255] ; NEVER try that :-) PS: as always - my code is probably far from optimal, but it hopefully does the job :-) Now the script: REBOL [] system/schemes/default/timeout: 0.1 if exists? %virus-ip-scan.log [delete %virus-ip-scan.log] log: func [text][ print text write/append %virus-ip-scan.log join reduce text newline ] IP-ranges: [ 172 25 7 [0 255] 172 25 37 [0 255] 172 25 14 [0 255] ] virus-ports: [ Sasser [1022 1023 4445 5554 9996] Blaster [] ] IPs-to-check: copy [] log [Start at: now] log Generating IP ranges ... foreach [IP1 IP2 IP3 IP4] IP-ranges [ if integer?

In their announcement, they stated NS plug-in will follow, they just did not clarified when. But - I share your sentiment . plug-in will not imo gain enough of acceptance if NS type plug-in don't come soon enough = at least imo this year. Most potential developers (not talking intranets here) will come from camps caring about alternatives pretty much. For many youg ppl IE as a browser is simply non-existant, but of course my pov is biased, as I come from computer related user camp, where alternatives are more often used than with average home user. Anyway - plug-in is cool even in its current form, just not stable for 1.0 release (still no working proxy support, random crashes reported). I think once RT solves such issues, they will start looking into NS plug-in once again, as we have some cool folks here who are fluent with C/C++ and who offered RT help to set-up Mozilla dev. environment, which according to some ppl on web is a bit chaotic sometimes ... One important issue which has to be solved in the future though is multiple plug-in instances per page, or banners are not possible. I hope RT keeps that request in mind to later not introduce incompatibilities once such support is added. -pekr- -- To unsubscribe from this list, just send an email to [EMAIL PROTECTED] with unsubscribe as the subject.

As from what you describe - you are probably very much dependant upon MS architecture, where various tools are well designed to fit together. We face basic problems - antivirus systems are not enough. We are thinking into plugging-in some adware protection tools, setting all our machines to automatically update Windows, and maybe even personal firewals in some longer future. My personal prediction is, that the situation will become only worse re security. But let me say that I can't somehow believe that IE is secure enough for you without additional settings/twists, but most ppl use it as-is, as it comes with OS. The fact is - you never know until new bug is found. And new issues are being found way too often to my liking ... As for getting getting enough facts about IE - just put some scan on IE + Win vulnerabilities - there is plenty of facts :-) I don't believe IE is growing in support. I read other reports stating otherwise and what is more - IE6 is not developed for 2 years already and new version will come with Longhorn (2006?), etc. Those are arguments, which could/should be put into consideration too - 11 - 13% of alternatives is not small number at all and besides that IE is no option for Mac users anymore anyway -pekr- Paul Tretter - Original Message - From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, April 21, 2004 6:02 AM Subject: [REBOL] Re: [Plugin] is cool The plugin module for MSIE is cool.

That is not about search replace only. xtml template is designed by our gfx designer, cgi/data part is mine responsibility.

Click it, and I do LIMIT 10, 10 Which fetches only 10 records, starting at 10.

Was this to any help? HY OK, guys, all fine answers. As for DB aproach pov, I think I can manage it, as I have some db background. Maybe I expressed myself a bit incorrectly. My problem is that of how to visually represent that. As I already said - I don't do gfx + html. It is done by our gfx folk. I can fill-in the table with appropriate info, but I was asked what should designer do to represent next-page visually. e.g. - once on first page, you can represent your results as: (1) 2 3 4 - - you click 2, you get - -- 1 (2) 3 4 -- Those page-continuation sections, can have various visual representations - as e.g. with counter - you can use html only with clear text, or you can compose it with bitmaps, etc. But there is no if, then, else awailable with html. So my question is, what is the right aproach to build html template for me to just fill in the data. Maybe the only solution is that designer marks html section where such next-page section will be placed, and it will be separated in another few templates I will have to plug-in? As you can see with above example, it is rather dynamic - when you start, there is no back button, as you move to (2), there is the back button, once you reach (4), there will be no forward button, etc. -pekr- -- To unsubscribe from this list, just send an email to [EMAIL PROTECTED] with unsubscribe as the subject.
[REBOL] Re: [Bot] email command Bot
It's a different problem, really. REBOL allows access to *all* of itself. So you get to see and manipulate *everything*. Some of us have gone down that road, exploring a lots of mechanisms that would be internal to other interpreters. What I am trying to say is that it is not reasonable to expect all parts of REBOL to be documented, simply because some parts are visible but essentially internal. The fact that some gurus have figured them out is a great accomplishment that results in nice libraries, but not something you should necessarily want to do yourself. It's one of the joys of having a fully accessible (reflexive) language. I see. However this self access to the interpreter seems a boomerang thing, as it allows to make powerful scripts but also allows for hacks that are not that simple to understand. IMHO at long people get discouraged by what they can obtain from the standard feature vs those that can be accomplished by the hacked ones. Yes, that is typical, sometimes a BIG problem for Rebol acceptance - I am only average programmer, but sometimes I look at even short script and am not able to understand easily and fast enough what it is supposed to do You see, Rebol has nothing natively that can provide access to any DB or XML, so it seems to be quite a self contained/isolated world. People have somewhat resolved this problems, but I see that using complex 3rd part scripts to access a DB is somewhat a drawback with respect having it natively integrated/supported. The same goes for XML parsing and building features. but now I have to object. What is si complex about mySQL protocol? 10KB? Yes, it is third party, but excuse me - when in python or perl - aren't their even more general functions in separate modules you have to include/load/call/whatever? I do'nt see anything complex about do %my-sql.r at all ;-) /Command version contains direct mySQL access, but maybe DocKimble could compress his mysql.r into binary format, so you would not see its internals and only API would be left for you, which is plain simple - open, insert, copy, close :-) OK, I think I know what you consider being a trouble - such third party tools don't use unified way to certain areas which we try to address. That is why I asked for thing as Uniserve - multi-protocol plug-in architecture, so that ppl would not have to start over and over again building their protocols from scratch. I think Maarten tried to address that by some rebol library - the best scripts put into some toolset, which could be used by many other thing may be Maxim's Slim - module system - Robert asked us to try that on AltME world, and I will - maybe it can solve some dependency problems etc. The problem with Rebol community is, that each of us uses some slightly different aproach, and that we can't somehow agree upon some standard, where others would use it and build upon it ... No, I was speaking about the free Core version, which is the tools I have been using since the beginning. I have not real use of View or Windows only dll access features. Windows only? I may not understand ... under Linux you get access to .so libraries of course.

[REBOL] Re: The REBOL async:// tutorial - take 1
Maarten Koopmans napsal(a):
Hi,
that stuff looks really excelent! Strange thing is, that even if the
code looks pretty straightforward, I don't understand every detail of
it, but that is what there are questions for :-)
handler: func [port [port!] state [word! error!] /local tmp cmd] [
if error? :state [print mold disarm state return true]
switch state [
connect [
; do HTTP request
insert port {GET /fg/anen.jpg HTTP/1.0^M^JHost:
www.3dwallpaper.com^M^J^M^J}
That one - raw tcp stream, right? I wonder if some kind of dialect (set
of functions) could be produced to handle that ugly MJMJMJ and GET
commands etc., as e.g. read/custom allows. Just a theoretical question,
if it even would be worth it, nothing more
false
]
read[false]
write [false]
close [
; get data
data: copy port
OK, so that one does not block right? And it is so just because we are
inside handler function, which is being called once some event happens
on port, so theoretically some data should be awaiting us. I just wonder
it comes in 'close switch part. We get here once other side closed
connection? So if I understand it correctly, we read it in parts, but
'read part does nothing, rebol is internally buffering data (how large
data is rebol able to buffer easily that way?) and once other side
closes connection, we can read it by copy (which will not block, even if
no-wait was not used), and whole data is being read out of the port
buffer at once? Well, I hope I am still on track :-)
Now for a simple server:
First we add a listening server port to the system/ports/wait-list, like:
Why? Is that needed? Am I right thinking it is because of View? Once
View starts, it adds event-port into wait-list and if we want to process
all various events properly, we have to go via wait-list?
either error? try [listen: open/no-wait tcp://:8000] [
port: open async://localhost:8000
port/awake: do handler
Above code somehow escapes my understanding :-) So if we are not able to
open listen port (because e.g. we are already listening), we open
connection on localhost to that port? What is that good for?
] [
listen/awake: func [l /local p] [
print Got connection.
p: first listen
remove find system/ports/wait-list listen
port: make port! [scheme: 'async sub-port: p]
that is something I never understood. That is why I was not able to
further more deeply adapt Sterling's proxy.r script. It contained way
too much port subport and proxy (as a port :-) stuff for my brain to
swallow :-) 'p is assigned first connected client. It does not contain
any sub-port, yet it can communicate. IIRC someone said, that sub-port
contains real communication port. But I don't understand the difference,
even without sub-port, I am able to send data here and there and I can
see it buffered in port/state. What is sub-port then?
open port
port/awake: do handler
false
]
insert tail system/ports/wait-list listen
port: none
]
so overall - it is clever - once first event happens on listening port,
we remove it from wait-list, reassign handler and insert it back into
wait-list. That sounds like nice constructor/init method in OOP :-)
As you can see, its awake function convert the accepted port to an async
one and sets the handler. So what is the handler then?
handler: [ use [ buffer ][
buffer: copy []
func [port [port!] state [word! error!] /local tmp cmd] [
if error? :state [print mold disarm state return true]
switch state [
connect [print Connected. false]
read[
append buffer copy port
while [tmp: find buffer newline] [
cmd: copy/part buffer tmp
remove/part buffer next tmp
do-cmd cmd
]
false
]
write [false]
close [print Peer closed connection. close port true]
]
]
]
]
The first thing to notice is the fact that we use 'use to create a context
that returns a function! value. This function (and only this particluar
value) has access to its buffer. By doing the handler block in the server
part above, every accepted port gets a copy of theis function value with
its own static buffer space. A very simple but effective trick.
cool!

Paul Tretter napsal(a): Yeah this was my current work around to use 0 as a timeout but I was a wondering why it was needed if there was no-wait. It was not imo. Your code was imo wrong for what you wanted to achieve: port: open/direct/no-wait tcp://:7000 x: 0 forever [ print x + 1 x: x + 1 data: first wait port ] Do you know what above code is basically doing? You opened so called listen socket - TCP channel assigned to you by OS. That kind of socket is able to accept new connections, nothing more. One there is new client asking for connection, it simply assigns it other type of socket, so called communication socket. Just look at 'probe of given port and look for 'local-port item - that is the port assigned to you by OS. So basically - what did you expect your above code will do? I think I can tell you :-) Your 'forever loop will hang on, untill there is new connection coming. Just open second console and type-in: client: open tcp://127.0.0.1:7000 and your 'x will counter will be raised by 1 - You created nothing more, than connection counter.

[REBOL] Re: starting to be really late!?
Karl Robillard wrote: Hey Ed, that's an excellent summary of how Rebol differs from other mainstream languages. Everything else in this post I have said before, but I like to restate my thoughts whenever this topic pops up, as Robert notes that it does, every few months or so. I believe the artificial limits placed on Rebol by RT is the problem and agree that the strategy is wrong. I don't want another platform and Rebol is doomed to failure if it insists on trying to compete with all the existing ones. I want Rebol as a tool to bind my existing platforms and applications together. And I have to ask why do you want to limit rebol in becoming kind of Arexx universal glue, when it can actually provide much more usability? I can see the main rebol concept as very good - the one of rebol block and mixture of code = data (even binary ones) principle. My opinion is, that there is not so much effort needed to push rebol in certain areas. How do you want to judge what aproach is right? You want kind of arexx, someone else might be interested in Authoring tool (right cyphre? :-). But then I often hear that that why to compete with Flash etc. kind of argument and my opinion is - that is not true. E.g. I have no intention (limited by lack of free time) to learn FlashMX to become fluent in such environment and besides that I think that some nice changes to View would eliminate such need. The problem of past of RT was imo their investors. I do remember when RT switched to IOS (Express back at that time) kind of strategy. I really disliked it. They had no corporate experience imo and what is more, even IOS development stopped while there is so much what can be done to make it better. While the glory days of RT employing several good coders is over, I think there can be way how to handle current situation: - community cooperating with RT - View 1.3 project is good start. I think that all ppl there are properly focused, no extra noise on particular channels etc. The difference between 1.3 effort and last year effort is clear - Carl's almost daily involvement, while in the past Carl appeared just once per 2 or 3 months to check. Other difference is often beta releases for betatesting - the way to go imo - RT concentrates on addition of general engines. E.g. - why to wait for RT to add particular functionality, feature, if we could add it ourselves? And yes, I mean addition of virtual machine, or at least specific area dialect engines for fast manipulation (e.g. working with image data). That way we could add additional effects ourselves, or in the case of RVM, code some additional ports/drivers to other environment ourselves, while stying fast - the advantage agains linking to libraries is obvious - rebol app would stay self-contained, RT would be freed from I-want-this-he-wants-that kind of feature requests. In fact, talking to Carl few days ago, he mentioned he thinks of addition of such principles into rebol more and more. That is imo a good sign. - also - Carl said that he could add more functionality into rebol, if we would help to find C source codes, .e.g. that he would be able to add RGB24 convolver in less than day probably. GIF saver and wav loader were also mentioned in that respect. So, it is also upon us. Similar thing I remember about .zip, .arj., .rar code, where the idea was to treat them like ordinary directories or to create schemes for them, something like zip:// ...The offer was made, but we (the community) failed to deliver ... so ... There are of course other things ... newer GC, async networking sitting in separate dev. tree, not yet merged, things like more granular event system, language extensions, direct draw modes etc. But - we should keep in mind we are short on resources.

Jason Cunliffe wrote: Is rebol ever going to catch up once again? We need Rebol with more media capabilities, better memory consumption characteristics and even better with general virtual machine in 2004, or probably never First - let me add that I almost completly disagree here. So, here we go why: While View is nice and capable of more, I really think Rebol's best strengths are not graphics/media, unless RT got massive investment and had some very different kind of marketing director working for them. imo Rebol is best for invisible stuff. It has to be defined what does invisible mean? Apache mode? Yes. Few other unix clones - no-way - waste of time. I e.g. did not understand, when Reichart told me, that he would like to see View for Solaris. Why? Because of FtpGadget? Excuse me, but now I call that total waste of energy and resources. Would it bring money to RT? Probably yes - but imo only short time. And Carl created Rebol because of some vision imo. And as for vision - sooner than later the world will be full of wireless mobile devices so I ask openly if we are going to stay behind or not. Something like View for Solaris or even systems like BSD is completly secondary point, if you think in some 3 + years. The only good thing is that such devices are going to be faster and faster, so maybe some Linux View version may run on them. As things stand I believe it would be a relative disaster for RT to spend too much more effort on /View devlopment. disaster? And that is why View 1.3 is under development? That is why direct draw modes were/are planned? That is why Carl told us that multimedia is his second name? :-) But maybe first - the problem with me disagreeing is - media - what is media? I don't think rebol should turn into media player - I just mean - ability to work with gfx faster. Better to integrate and use make-swf, what? Why? :-) What is the single advantage of making flash in rebol? That you would be able to run your rebol app inside the browser? Or where can I find flash and not rebol? Unless there is one-button-press conversion of rebol VID app into flash, it still means to program separately for View and for Flash ... and work on tight useful Flash integration. Look at the cool swf2exe prodcuts which have come out Screenwaever, Northcode, FlashStudioPro. That's easy money and opens up desktop flash applications to compete with Rebol very quickly. FlashStudio pro adds 400 fscommands including socket, http, ftp, mail, file i/o.. What more does one want or need? Even a Rebol-based swf2exe for Windows, Mac and Linux [in that order] could be a very successful and useful product. And a viable way to introduce Rebol to much larger and visible audience . That can be done without any need for Flash. The mobiles will follow. Rebol Projects worth investing in? How about a really *great* http server in rebol with integrated tfp, xmpp [Jabber], mail etc.? I can install Apache in 3 mins, configure in 2 - so 5 min to run profi http server on my desktop machine. You mentioned Jabber - so, OK - that is something i agree with, if you think something like more advanced IOS server, with direct communication and also polled communication, ability to use some file-sharing principles, sync to multiple servers ... kind of grid of various protocols, that would be cool. I can imagine rights, roles, rules, workflow engines, which would allow you to model various scenarios - that is REAL business oportunity, and it is a pity RT dropped IOS development - it could be much better. How about a really good mod_rebol component for Apache? I agree - but then - fast-cgi is not all that bad and you also mentioned money - how does RT makes money with that? How about rebol for bluetooth/wifi enabling digital video and still cameras? Let the others build media engines, let rebol be the modular engine they use to communicate. So now I hope I reached the point which explains it all. I should not mention media - as by media I mean - fast, smooth refresh/movement of elements around screen, fast effectcs, nothing more - I in no way meant RT should duplicate works of others and make native divx, avi whatever codecs inside. I fully agree with integration. In fact - my pov is, that RT should done the most general things ever and the rest should be done by user-base. My top priority is: - general VM dialect - which would allow for to use subset of commands, would be fast and would not require to write external modules in C, as they mean end to cross-platform scripts unless ported to certain platform. TAO did it right with Intent imo. btw - on AltME world Carl told us, that such kind of VM would take one person average month to code. Imo worth real consideration then. - if not general VM, so dedicated VMs then - we call them dialects - currently we heave 'secure, 'remove-each ... we want at least other for fast gfx handling. - language

Sorry about that but life is like that. That is not imo needed. AFAIK even RT is interested in browser plug-in resurrection. Of course I have not studied consequences of the plug-in problem MS was sued patent-wise for. As a start, I would welcome something like following: 1) View engine - encapped app 2) minimal desktop - current View desktop is way too much similar to typical OS desktop. As for browser-plugin kind of app - users are NOT looking for rebol and its related docs, but they visit certain sites and want to try to run certain x-inet-apps. I have seen Java Webstart - it is very similar of GO View desktop button section, just nicer and with some auto-update abilities 3) autoupdate - 3 levels - a) core engine (plug-in) update - only needed when new version of View is released b) desktop (navigation app, call it whatever) package update - kind of similar functionality as how IOS desktop is updated c) particular end user app update - default setting via context menu (or other way) to allow or disable auto-update, notification of user of new updates etc. with ability to download them manually 4) installation - it would be good if ti could be installed as other plug-ins ... users brought to certain download area, detection of browser platform, offer of certain app. User would select place of installation (placement) and if possible, settings like proxy would be set automatically 5) new apps. So - once some site posts .rpl (whatever .rpl = rebol player), user would click it, and if rebol player plug-in is already in-place, it would be started and added to player's list (desktop) 6) in some distant future RT does plug-in with ability to display inside of browser window, but I think it would not be needed imo for kind of apps as demos, game packages, but would be handy for VID based forms embedded in your html presentation ... That is my pov, I even dare to think it may be a killer app, if promoted a bit and if it would be deployed into user's web experience and would not be difficult to set-up ...

why there is DIV tag available?
It's placed at the start of each page after the first page, using a
Rebol script fragment like:
First_Page?: true
;...
; Inside page creation loop:
either First_Page? [
First_Page?: none
] [

I also make sure that I use this tag:

http://www.w3.org/2002/04/xhtml-math-svg/xhtml-math-svg.dtd;
for each page, to make sure the MS IE switches into the right mode. If it's
not present, MS IE 6 interprets HTML and CSS as if it were an older browser
complete with bugs!
I always thought that kind of info is just absolutly unnecessary -
thanks ... there is something to learn each day :-)
I also have two different media sections in my .css stylesheet, like:
@media screen {
body {
background: url(Wiki.jpg) #FC repeat-y fixed;
color: #00;
margin: 0px;
padding: 0px;
}
.Left-Column {
position: absolute;
}
...
}
and
@media print {
.Left-Column {
display: none;
}
...
}
Interesting. Yesterday I read some CSS compositing docs and I have to
admit that it looks well thought out. Not that View would not be thought
out, but View compositing ommits various output devices/media-types.
What we call 'face they call 'box. It will be interesting to see, where
Carl gets View further, as we badly miss color text capabilities, and
once introduced, how they will complicate View/VID usage. I even thought
for a while that there could be some converter from View to css
compositing as we have flash dialect currently. Don't know if it is
easily doable, but imo possible. We would get View display in browser.
But what about events?
OTOH - studying css docs for one day I have to say that it is way more
complicated than View. Maybe just a question of becoming used to
different concept? What do others think?

[REBOL] page-breaks in html or pdf?
Hi, our company is sending aviso documents to customers. Aviso is in html form or in pdf form. I have to say, that it is probably generated by some SAP automat. The code is pretty ugly - strict css usage - placing ALL elements onto absolute pixel positions. The problem is, that if there is more than one doc for customer at one batch, it is generated as multi-doc document (html or pdf) - but - some of our customers complained that it is really difficult to print that way. I chcecked out and did not find any way of how to issue something like page-break in html. It is probably not even possible. What about pdf? Is there any chance to insert page-break into pdf doc? So far the fastest fix seems to be parsing html doc, dividing it into separate files - I could create some encapsulated tool for that, but I would rather fix problem in our primary ERP system than go for workarounds ...

I would hate to redownload 500KB each time just because someone changes one function in script ... The MS-way of providing everything and keep it out of the system works very well. unfortunally its not the MS-way, some stuff is always placed in system-dirs. Overwriting another version.

I thought that Robert is suggesting encapping our apps, which imo leads to redundancy. I also heard official places stating, that it is not too much - but hey, who started Rebol just because of being more efficient? What about mobile devices? So you encap your app and you let your users redownload it each time just because you change one color of a button? :-) I think that - 1) Rebol should become engine - sitting on our HDs, being able to update itself eventually - kind of JVM. Then you could just distribute your scripts 2) You distribute your app, but rebol is separate and your app is kind of compressed package, so you can redownload only your app. Both points save you from redundancy, wasted bandwidth. If your tool will be downloaded by 10K ppl, you will sing different song, if you are supposed to 10K * 50x app, or 10K * x package Rebol enables us to provide apps this size. Why should we introduce risc of malfunctions? When speaking of malfunction, I can tell you following - current situation is just that - malfunction. View should imo take different aproach - register/install into registry only when forced to. So, what is your .r registered to? Base? Face? Core? Command? View? Which one? 1.2.1? 1.2.8? 1.2.10? Command? View/Command? Eh? I hope that if R# sees the light of the day, there is the promise of ONE single executable = kernel, and the rest being modules. I remember Carl stating that he is father of modular amiga system, but rebol is not modular, componentised yet. And I also remember someone stating, that current state (product diferentiation) is so because of marketing reasons. So - don't you hate when marketing stands in the way of technology? ;-) If it does not work, user spends a lot more time fixing a problem then downloading everything. You know better than me that it can be solved by semi-intelligent system. Amiga works that way, libraries have their version number - what is the problem? So you better like compromises like uncomplete sound system, no support for mp3 etc., because it would make View big? Well - that is way to nowhere. If sound component would be separate binary, library, module, component, call it whatever - you would not mind it having e.g. 200 kb, but with current state it would simply make View too big for some ppl to like it. Regarding IOS, all scripts work standalone, there is no script which does another. And that would be very simple with ios-distribution. IOS is different. And while it is nice architecture, its main drawback is just that - all scripts work standalone and I hope competent ppl do something about it to take IOS further.

Ged Byrne wrote: I've read the recent 'losing the case' thread with interest. Personally, I've just come to the end of my honeymoon with Rebol. I've been throwing to gether 5 line scripts that do what pages of Java or VB do in 5 pages. I've stopped saying 'Wow,' and I'm starting to ask 'How.' The problem is that, given a blank piece of screen, where do I begin when devising my own code to solve my own problems. What is the starting point. Different languages have their own starting points. In VB I start with a blank form, dropping controls and then writing the event handlers. Well, I can tell you one thing. I didn't like that aproach. I worked with VO, which was not so form based (which is imo bad aproach anyway), but with main window, defining menu, what menu items refer too, etc. - I hate those delphi/VB MDI apps. But that is not the point - even with VO, there was lot's of unneded stuff predefined in form of prebuilt apps, templates (even changeable but anyway) ... all this stuff provides you own logic of how child windows are stored, referred too, dbases organised etc. To not end with kludge, our team did exactly following - deleting whole stuff and astarting with main loop - we build our own system framework, classes, applied some DOS based keyboard navigation thru whole IS, we have done things like localisation and remote automatic update, we removed registry crap dependency etc. - and we were lucky . In Java I start with an object model. I identify my objects with methods and properties and then start composing the relative classes. That nearly seems as ideal case for project goals identification, but then I don't understand, what is your problem with rebol? If you are able to identify your goals with java, why not using rebol? After all - IIRC someone created class/method aproach for rebol too ... In Perl or Ruby I start with the input stream, usually a file, and start heading for the output stream. I don't understand here What is the starting point with Rebol? Given a problem and an empty .r file how do I start growing my problem? With a form to enter the data? With a set of objects? With a set of functions? By defining a dialect? Hmm - as I said - you have to learn how to correctly identify project goals and how to fulfill them. Deciding between objects, functions, dialect - is after step. I will try to define my aproach later, but let me get back to dialects: I don't know if I am alone, but Rebol dialects (or dialects in general) can be cool thing as well as they can become very tricky. Rebol dialects are completly free form, so dialect author can introduce stuff looking as coming from Mars, as well as it can look as any other programming language :-) The problem is, proven using VID, that dialects don't fit rebol language correctly. I tried to think about it for a while, but I am not sure, how you can eg. dialect to work with official rebol help? How can you know (talking VID now), what styles are available, what are their facets? Not to mention catastrophe, when you need to mix dialect with rebol level (button OK with [rebol-code-here]) - you suddenly deal with whole underlying View infrastructure - and once again - there is no help mechanism for objects, so the only thing you are left for in the case of object is to 'probe it - I can guarantee you, that only handfull of ppl understands how styles are constructed, when does it happen, how whole event mechanism flows etc etc. Now general question - has anyone thought how to make this situation better? I am not sure there is an easy answer. As far as VID is concerned, I propose: - VID 1.3 - provide users with more robust and encapsulated styles (tree, grid, tabs) so ppl will not need to touch underlying engine too often - fix inconsistencies and bugs - new level of docs are imo needed - View engine description, working with events, effects at face level ... show how to build UI in non VID fashion. Then start to explain VID, e.g. single button style ... explain how and when certain things happen and show us how to customize button and build own style get-style 'button output is far from being enough ... But that is just VID of course ... There seem to be so many approaches, but no single method affords itself? OK, one other problem I can see with rebol is - lack of frameworks. Maybe I now understand your java aproach - maybe you have I have all and I have nothing at hand feeling with rebol. Sometimes I have feeling that if you want to do something using rebol, you have to start over and over again - from scratch ... missing more general mechanisms to work with. I don't want to use async:\\whatever kind of stuff - I want RT to decide what is good and what not, and if it is good it should be added to rebol, simply to provide such common base to all of us.

If I've some computing intensive algorithm, once more, I've to state it in a coop way. And I (my very personal opinion based on my experiences with that kind of stuff in REBOL) find that decomposition rather boring and the result quite hard to maintain. Imho, first class continuations would help in this situation, but that's another topic. So let's do first-class continuations on the mezzanine level, re-implementing reduce as block interpreter that recursively evaluates the values supplied. And then redo 'do ;-) , retrofit load etc. Anybody interested? And when we have done that, why not make'em first class distributed in our full reflexive meta-language?

You can call 'reposition function with block containing any number of
options you want to decide upon which is coming first. It will just do
plain search, analyze its postion, sort resulting block and reposition
your parse input string so that the parser pointer points to first of
the options, so you can directly apply HREF=, SRC= etc and you can
be sure one of them is there ...
Well, I don't know how it is robust, but tried with mytext: read
http://www.rebol.com and it seems it needs further tuning :-)
following might get you better results:
mytext: read http://www.rebol.com
src-rule: [{SRC=} copy target to {} (print target)]
href-rule: [{HREF=} copy target to {} (print target)]
parse/all mytext [
any [
mark: (mark: reposition mark [{HREF=} {SRC=}]) :mark

What is more - if you are not familiar with those tools, forget you start utilising your tool easily. It does not matter you know what is object programming about - you have to learn classes, events, their logic, etc. If you already came to rebol, it is clear you want to do some apps your way. E.g. with VO, we scrapped all templates and produced our logic - I hate those templates which can solve easy cases for you, but once you go deeper and deeper in a problem, you end-up with kludgy code. So in the end we had some small IS sales system done. Do you think our users care what it was programmed in, or how sophisticated object logic it uses? :-) I use minimalistic aproach - ask yourself : - does it work? If so, who cares what sophisticated tool you used - users/customers don't! - Is it fast enough? Now I mean mainly speed. There is old trade-off of speed of scripting languages. Only morons can claim such things nowadays, at least for general apps. Fast enough is simply fast enough. I often can hear - but my C++ code would work 10x faster. Well, ppl claiming so very often forget the fact, that today's PC is x times faster than yesterday's server ;-) so - for general business apps, rebol is more than ideal. Forget some video, sound capabilities - we are slow and not there yet, forget writing MS Office clone using rebol etc. - don't try to provide your app with native OS skins! Well - that is my suggestion. I know some ppl think otherwise, but I can tell you, that my ppl notice my apps, because they look slightly different. E.g. REBOL IOS has very pleasant feeling - if it would have native Windows look - it would just look as other windows based app ... so - use the difference as your advantage! - Does it behave consistently? And now take care! VID is still not consistent in some cases. While I prefer different look of app, I know that what ppl hate is different app behavior (I talk keyboard navigation here). But there are some patches mainly from Romano, which help in that area. And - after all - once you will become more fluent with View, you can change lot's of things yourself. - more styles - ask Cyphre for tree-view, list-view, tabs, menu etc styles - they are very nice, even in beta. There was VID 1.3 community effort but it is not finished. I know RT wants to do something in that regard, as current VID stopped imo in some 80% of perfection (missing styles, some inconsistencies, capabilities ...) - time to market - I can bet that Rebol will allow you to very quickly prototype your app. You will be designing it around your thoughts. Rebol is first environment which provides me with such feeling. e.g. in VO I had to wrap my thinking around strict object logic. Rebol is free-form. - what rebol lacks a bit is simple built-in database (IIRC Gabriele did something in that regard but I don't know its state). So it depends what are your intentions. Rebol/Command has ODBC interface, using View/Pro you can use Firebird wrapper and even with non-profi Rebol products you can use e.g. Postgress and MySQL - we have cool folk called DocKimbel here, who did really nice drivers ...

Thanks all for answers!

[REBOL] rebol and kiosk systems embedding ...
Hello, part of our project is gonna be - KIOSK systems. We just looked into some at Invex computer show. They are pretty expensive, so we will eventually produce few kiosk systems ourselves. However - the questioin is - software. We can go several routes: 1) by some 3rd party software - but we are not sure they will sell us without their kiosk system. 2) build such sw ourselves. What is needed? a) customized browser, which will run in full screen mode and will prevent user of touch screen to leave the environment back to OS desktop. Such environment has to provide us with the ability to display virtual keyboard, which would allow to enter urls, fill in forms, etc. b) it has to allow for the admin to enter allowed urls, etc. - we don't want to let ppl to browse the whole web, right? :-) (maybe kind of a proxy would be needed?) c) maybe to allow even visual mixture with Rebol code, - dialog appearance - but can we have forced (modal, non-modal - I never know which one represents what, but you surely understand :-) rebol based window in the front of other screen content? Several ways to implement 2) A) do everything in rebol and forget browser - not too much acceptable, as I would lost ability to delegate design work to designer, who is not fluent with VID (although he will learn it in the future). The idea is to allow combination of e.g. browser, dialog boxes in rebol, full-screen rebol content, Scala Multimedia content etc, we will see how it can all be combined B) use browser - but as I said - we would have to be able to adapt browser's environment, to allow some custom buttons for the kiosk purpose, virtual keyboard display, etc. We would definitely go with Mozilla (cross platform) and probably XUL, but I am not sure yet, if it will allow us to customize UI to our liking. If anyone is experienced in that area, I would appreciate some input here ... some XUL references: http://www.mozilla.org/xpfe/xulref/- programmer's guide? http://www.xulplanet.com/ - portal ... C) what we saw during the show was - external configurable environments, with embedded browser (mostly IE I think). I tried to look into Mozilla embedding API, but it seems pretty complex to me. Well - I am not sure I want to create cross-platform rebol browser anyway (although it could help IOS a lot, as it misses just that kind of integration - no ability to display embedded html content). I would like to ask, if anyone tried to embed external app into View face? Is that even possible technically? Simply not linking Rebol to Mozilla API, but to tell Mozilla to run inside defined window. But I am not sure it would be sufficient, as parameters would have to be exchanged between those two anyway (virtual keyboard entry e.g.) Embedding Mozilla API link (for those, who are skilled enough and would provide rebol community with a gift of getting ability to display web content into View layout. Mozilla is free and cross-platform, so no problem on that side, what would be needed to distribute is just Mozilla run-time and rebol wrappers :-) http://www.mozilla.org/projects/embedding/embedapiref/embedapiTOC.html Well, as always, I will appreciate any kind of input.

[REBOL] Re: rebol and kiosk systems embedding ...
Just replying to myself but maybe as a reference for others - there seem to be more to the mozilla than one could think - it seems to become a platform rather than being simple browser :-) http://www.mozdev.org/projects.html - what a bunch of projects ... I don't know why, but e.g. XUL XML UI description language seems to me rebol like - clean, simple enough, well though out (especially chrome:// - they use port-like principle we use in rebol :-) http://www.xulplanet.com/tutorials/xultu/ Well, talking to myself here in the morning ... everybody seem to be asleep :-) -pekr- -- To unsubscribe from this list, please send an email to [EMAIL PROTECTED] with unsubscribe in the subject, without the quotes.
[REBOL] Re: rebol and kiosk systems embedding ...
bryan wrote: C) what we saw during the show was - external configurable environments, with embedded browser (mostly IE I think). Well IE did make an initial push towards developers for the KIOSK market, tied in with Windows CE I believe, so that would be logical. A propos XUL, I started with that when it first came out but dropped it cause namespaces were not being handled correctly, i.e you could not bind the namespace to a prefix but had to use the xul prefix all the time. Would be interested in knowing if that's fixed. I don't know - according to following site, there is also easier way - but still some options don't seem to work. http://tln.lib.mi.us/~amutch/pro/mozilla/ I also got to the article describing how Borland faked embedding Mozilla into their Kylix - they run mozilla process with -width and -height parameters and just assured that Kylix can communicate with mozilla process to exchange keyboard focus info, etc. Something like that could be sufficient - I would run Rebol top and bottom bar, easily do virtual keyboard, but command-line switches don't work for me here yet. As you can see, old Communicator feature kiosk and super-kiosk modes - http://developer.netscape.com/docs/manuals/deploymt/options.htm Mozilla doesn't and my suspicion is - the way to solve it is to use XUL or some other tweak ... List of Mozilla's command line options are here: http://www.mozilla.org/quality/browser/front-end/testcases/cmd-line/index.html -pekr- -- To unsubscribe from this list, please send an email to [EMAIL PROTECTED] with unsubscribe in the subject, without the quotes.
