[REBOL] How to reset VID/guide?
Hi, I have the following layout: view layout [ across a: txt test1 guide b: txt test2 return c: txt test3 return d: txt test4 ] And I want to be 'd in line with 'a. How do I get rid of the 'guide once set? I just want to disable it until the next 'guide happens. Robert I never actually use guide, but this seems to give you what you want... view layout [ across a: txt test1 guide b: txt test2 return c: txt test3 return guide a/offset d: txt test4 return e: txt test5 ] Hope that helps. -- Carl Read -- To unsubscribe from this list, just send an email to [EMAIL PROTECTED] with unsubscribe as the subject.
[REBOL] Re: [port/skip]
From Tracker#295
SNIP
[skip does not work with open/binary/direct]
file: open/binary/direct/skip does not work.
at file n does not work
skip file n causes REBOL to hang.
These operations should either work or not be allowed on files opened with
/direct.
/SNIP
Regards,
Ashley
Ah - good they know about it.
In the meantime, this is my work-around: First, what happens if you use append...
write %test.txt 12345
x: open/binary/direct %test.txt
append x to-binary abc
close x
read %test.txt
== abc45
And my solution using loop and copy...
write %test.txt 12345
x: open/binary/direct %test.txt
loop size? %test.txt [copy/part x 1]
== #{35}
append x to-binary abc
close x
read %test.txt
== 12345abc
And given this behaviour, you may as well use insert instead of append.
Also, would copying larger blocks of bytes instead of just one at a time be faster or
better?
Thanks for all the responses,

[REBOL] [port/skip]
Are there any known problems with the use of skip with ports? As on files it doesn't
seem to work for me...
write %test.txt abcdefghijkl
port: open/direct/binary %test.txt
copy/part port 4
== #{61626364}
close port
port: open/direct/binary/skip %test.txt 4
copy/part port 4
== #{61626364}
close port
but does with URLs...
port: open/direct/binary http://www.rebol.com/
connecting to: www.rebol.com
copy/part port 4

close port
port: open/direct/binary/skip http://www.rebol.com/ 4
connecting to: www.rebol.com
copy/part port 4
== #{4C3E0A3C}
close port
And if I use skip on an already opened port, ie...
port: skip port 4
it'll work if it's a file, but if an URL it'll just hang with nothing returned.
Easy enough to work around this behaviour with files, but does skip with URLs only
work when opening the port? Or am I doing something wrong?

[REBOL] Re: [port/skip]
Hmm - I was badly wrong about skipping files after an open working okay - REBOL
totally locks up when I attempt this kind of thing... (Taken from the Users' Guide:
http://www.rebol.com/docs/core23/rebolcore-14.html#section-8.4)...
fp: open/direct/binary %file.dat
fp: skip fp 10
My example...
write %test.txt abcdefghijkl

[REBOL] Re: [text-list] faces
What's the path to the faces of the text in a text-list? I assume they're a block of faces somewhere in the text-list object? No, sorry, there is no block of face in a text-list. The text-list is one type of face called iterated-face : there is only one subface. The pane is not a face or a block, but a function that is called to display each data with the subface. the secret of text-list is in its 'init block and its 'text-pane function. Ah - finally! Never noticed text-pane before. (Which is most strange...) What I was wanting to do was to have different colored lines of text. Can now... view layout [ t: text-list aaa bbb ccc button Change [ repeat line 3 [ face: t/text-pane t/iter line insert face/text join line face/font/color: pick reduce [red green blue] line show face ] ] ] Many thanks. -- Carl Read -- To unsubscribe from this list, just send an email to [EMAIL PROTECTED] with unsubscribe as the subject.
[REBOL] Re: [text-list] faces
Not a perfect solution, because as soon as you click a line, all lines are redisplayed with the last color. As I found out... It can be done by changing the text-pane func itself to let it change the font color or something else. Just take care of that : text-pane must return the iter face or none : view layout [ t: text-list aaa bbb ccc with [ text-pane: func [face id][ if pair? id [return 1 + second id / iter/size] iter/offset: iter/old-offset: id - 1 * iter/size * 0x1 if iter/offset/y + iter/size/y size/y [return none] cnt: id: id + sn ;* HERE IS THE ADDON : ALTERNATE COLOR EVEN/ODD iter/font/color: pick [255.0.0 0.0.255] odd? id ; END if iter/text: pick data id [ lines: at data id iter ] ] ] ] Yes - much better. Though if you're deciding on the color based on iter/text at that point, it gets it a line out. Moving it to the following if block gets it right though. ie... view layout [ t: text-list aaa bbb ccc with [ text-pane: func [face id][ if pair? id [return 1 + second id / iter/size] iter/offset: iter/old-offset: id - 1 * iter/size * 0x1 if iter/offset/y + iter/size/y size/y [return none] cnt: id: id + sn if iter/text: pick data id [ ; EXTRA CODE iter/font/color: either iter/text = bbb [255.0.0][0.0.255] ; lines: at data id iter ] ] ] ] Thanks once again, -- Carl Read -- To unsubscribe from this list, just send an email to [EMAIL PROTECTED] with unsubscribe as the subject.

=== Original Message === http://www.errru.net/rebol/fun/rdm.r Right now, this is just a nonviolent and incomplete demo, which needs the latest view beta. Some features: - everything 100% REBOL - no texturing (no OpenGL), but changing the wall drawing code is easy. - 3 DOF with fast hidden line removal (front to back occlusion test) - adaptive time step physics - can be rewritten for 4 DOF (no up/down or tilting rotations) - can be rewritten for rooms with arbitrary, but convex 2D outlines - can be rewritten for graph-like room topology (right now it's a grid) - can be rewritten for OpenGL rendering - no room-over-room capability It will still take a lot of time to make a fun game out of this :/ It would be interesting to see if REBOL can do real-time streaming of game state over networks.

Dunno. Any suggestions, examples? Maarten and Hallvard have given good replies, to which I'd add that using the query-string to keep track of both the search-query and page-number is a good idea, as then people can bookmark their searches. ie, something like this... www.someplace.com/db ; search for da do returns... www.someplace.com/db?search=da+do ; next-page clicked returns... www.someplace.com/db?search=da+doskip=30 This also has the advantage of allowing people to edit the query by hand, thus jumping to near the end (say) of a large result by changing skip=30 to skip=300. Useful if the results have been sorted. There's a slight problem with that in that the database may change before the next-page button is clicked on, so you might be skipping over data you really should be displaying. You could get around that by keeping a tempory file of the full search results and have an id pointing to it, but then it might show items that are no longer in the database so it's really six of one and half a dozen of the other. The closest thing I've done to this is... http://cybercraft.nebularis.com/NZnews/NZnews-home.r but it doesn't use SQL and the search just stops at about 500 results - no paging ;-) But where you are is all tracked by the query string, so if you're looking at a weeks' results for a date and change the date, you still get a week's results. -- Carl Read -- To unsubscribe from this list, just send an email to [EMAIL PROTECTED] with unsubscribe as the subject.

On 20-Mar-04, Luke Orlando Emmet wrote: How would a rebsite (or a flashsite etc) get searched by Google?? From a technical POV, a rebsite wouldn't be difficult for Google to search - it just needs to look at the script's header. I doubt they'll bother till there's millions of scripts about though. Out of curiousity, I've just been using Google to try and find REBOL scripts and a search for rebol .r (without the speechmarks) ranked my solar-sim reblet at 5. Like it's had about 50 hits and been online for all of two weeks and it's at number 5 in a search for rebol .r?!? It's also the first link shown with a .r extension. So, what's different about my reblet? Well, because of the way my host handles REBOL scripts, (they have to have a .r extension), I couldn't have the reblet's page point to a script with a .r extension as it'd generate an error. So I gave the script a .reblet extension and the reblet's page a .r instead of .html. (Yes, it's a REBOL script too, hence its counter.) Moral of the story? HTML with a .r extension can get listed high by Google, whereas scripts with a .r extension don't seem to. I'm now toying with the idea of changing the .reblet extension on the script to .html to see what happens. ;-) -- Carl Read -- To unsubscribe from this list, just send an email to [EMAIL PROTECTED] with unsubscribe as the subject.

If you do, try and define REBOL on a few sites. define is one of Google's key words. Try typing define perl into Google to see what I mean. Google doesn't have a definition for REBOL yet though, so we need to trick it into having a good one. Hmmm - just noticed such Google definitions seem to be mostly taken from glossary pages, (perl's a good example: http://www.google.co.nz/search?q=define:Perl ), so finding the right glossary to add REBOL to would be the way to achieve this.

The Desktop's designed for adding such features. If you look in View's Desktop directory you'll see a script called services.r You can add extra services to this which place menu items on the View Desktop which run a script of your choice. As an example I added an Open to the Desktop menu to allow me to use the View file-requester to select and run scripts. To do this I added this line to the services.r script... service Open %/path-to-REBOL-directory/local/requester.r (Can't remember if the full path to the script is needed and whether it also needs to be in a directory called local - but that's how I did it, anyway:) ...and this is the script it runs - requester.r ...

If you try it and it doesn't work, let me know what problems you have. (Written a while back, so probably not how I'd write it now.) So, you should be able to write an URL manager to run as a service on the Desktop. The problem with the Desktop is it /is/ a desktop and not a browser.

For example I would like to have in my dialect code words like this one: objects/1._x ** Syntax Error: Invalid decimal -- 1._x ** Near: (line 1) objects/1._x As you can see, it's recognized as an invalid decimal. So here comes the question. Would it be possible to change this behavior to something which we could use? There were already some discussions on mailing list about this issue months ago, but I still don't know your opinion. I think the best way would be to handle these 'invalid' words as a special word which would not be able to hold some values but I would be able to parse this word as a normal string. If it will be a problem maybe it would help to use some refinement in the 'load function not to throw these invalid datatype errors and convert these invalid datatypes. If you would make this change, I would be able to make for example functions as are known in other languages for example: myFunc(a, 2, a + b) because loading such a dialect would not throw error like: load [myFunc(a, 2, a + b)] ** Syntax Error: Invalid word -- a, ** Near: (line 1) load [myFunc(a, 2, a + b)] The problem would be that real errors wouldn't be caught. Maybe we need a special type of block that would allow this? (Which would require a new datatype - well, two new datatypes - the special block and an unknown! datatype.) Which is non-trivial I suspect. For your Flash dialect Oldes, have you thought about a two-pass approach? The first pass would parse the file as a string, converting your myFunc(a, 2, a + b)s and so on to strings (or what datatypes or group of datatypes best suit them), with the second pass performing the main parse. -- Carl Read -- To unsubscribe from this list, just send an email to [EMAIL PROTECTED] with unsubscribe as the subject.

To capture an error object you can use something like this... error? err: try [1 / 0] == true probe disarm err make object!

Just keep the image in the original format, i.e.:
image-data: read/binary %img.gif
Then later you can LOAD it:
img: load image-data
It works! Never thought of using LOAD that way. Thanks! :-)
Also, if you're dealing with an image created by REBOL, you could use
save/png to create a compressed binary of the image. ie...
pic: to-image layout [backdrop black box A picture]

10) Image processing
Is it possible to create new images (in memory) by adding other
images to the original image at certain coordinates ?
Doing it in a layout and then using TO-IMAGE is the simpliest, though
you can work directly on the image datatype...
pic: make image! 2x2

pic/1: 255.255.255.255
== make image! [2x2 #{FF00}]

Gets a lot trickier to put images into images of course, but is
possible.
Having tried to overlay transparent GIFs in a VIEW layout, I noticed
the transparency attribute doesn't seem to be preserved ? At least

11) VID controls
If I need certain additional features for a basic control - like a
progress bar or slider,
how do I add these ? Do I need to edit the dialect ? For example, I
want a progress bar with tic-marks as well as a non-continous
filling of the bar.
So, is there any way to sub-class controls easily to enhace their
functionality/appearance without having to re-write everything from
scratch?
Pass...
12) Is there any really thorough information available on ACTIONS
and EVENTS with REBOL/VIEW ?
They documentation on the REBOL pages seems a bit 'poor' on that
matter. I don't know yet, how these things are really done behind
the scenes.
Have you seen the HowTo on FEEL? (Link above.)
13) I didn't see any designated function to set pixels at certain
coordinates in a layout-
my workaround was using the line word - with 1 width/height.
How is this really done ?
That's one way, the other being to work directly on an image in a
layout. ie...
pic: make image! 100x100
view layout [
image pic rate 10 feel [
engage: func [face action event][
if action = 'time [
poke face/image random (length? face/image) / 4
random 255.255.255
show face
]
]
]
]
14) How do I catch mouse events - such as a mouseover event ? I read
about 'over' - it seems to do exactly what I need - I want to
display controls in a certain area only when the mouse cursor is in
that said area. Also, that functionality could be used to add
tooltip-like behaviour to buttons
and menus.
Once again, see the HowTo on FEEL mentioned above.
Again: thanks for your help and patience folks - it's really
appreciated !!
Hope that helps!

[REBOL] Re: FTP scheme was Re: Reading empty directories via FTP error
Appologies to Brett, Gabriele and any others who've responded to my missing file-names problem. The cause was REBOL's FTP path and my FTP clients' paths don't match. The directory I was looking at with my clients was site/web/ but with REBOL this needed to be site/../../web/ (ie, back up two directories.) With REBOL, site/web/ is actually pointing to site/../../user/web/ where user is a directory set aside for testing and its web directory actually contains 10 files and directories that match site/../../web/ Blugh! From this I assume my FTP clients can detect they need to start up two directories from the host's URL, whereas REBOL can't. Would this be possible?

That's why the port none error will occur. If I'm right, then I

That appears to cause less logic change in my eyes - but I'm only guessing. Code included below in compressed form. No go I'm afraid. I get the same results as with Scott's code, in that it works on the one site but not on the fixed Nebularis site. Anyway, I'll examine both your versions and the original and see if I can come up with something that works. Will get back to you on this. Going by the other posts to this thread, it looks like the problem is too loose FTP specs, rather than REBOL. -- Carl Read -- To unsubscribe from this list, just send an email to [EMAIL PROTECTED] with unsubscribe as the subject.

Maybe you should trace the connection and see what conversation

Ah - thanks. Didn't expect it to be so simple.
So, here's the end of the trace output when it reads a directory with
some files in it...

As far as I can tell, the extra...
Net-log: [

Net-log: 200 PORT command successful.
on the end there just before the error is the only difference the
trace shows. And I'm still none the wiser...

No special permissions required nor builds to do. The only tricky stuff is if you need some fancy Apache httpd.config tweaking. Anyone else care to confirm or correct this point..? I'd say there's four types of hosting services with regards to REBOL... 1) Those that openly support REBOL. 2) Those that'll help you to get REBOL running, even though they don't really know it. 3) Those that'll let you run it - if you can work out how. 4) And those that'll say no if you ask them if you can install it. Then again, a host that offers Command would beat one that offers just Core. -- Carl Read -- To unsubscribe from this list, just send an email to [EMAIL PROTECTED] with unsubscribe as the subject.

[REBOL] Re: Basic Script Calling Commands
On 30-Oct-03, Ben Minton wrote: Hi List. Today, I bit the bullet, installed another hdd. Reinstalled RedHat with a GUI. Got Rebol/View. , what is the command to call any script? I tried Do %script.r and got an Access Error Message : cannot find Yes Do's right. Does this mean that I have placed Library.r into the wrong location? Yes, or that REBOL's startup directory isn't where you think it is. At the REBOL Console enter... what-dir to see what directory REBOL is currently pointing to, and... list-dir to get a directory listing. If REBOL's startup directory isn't the one you want it to be, then you've probably just not entered its path correctly when you installed View. I've had this problem, and found it easiest to just un-install View then re-install it again. To un-install, enter... set-user at the Console and click on un-install. This won't remove View or any important files. All it'll mean is that when you run View again you'll be put through its install process again, including where its home directory should be. This should be entered in REBOL file format. ie %/home/rebol/ or whatever. Hope that helps.
