Group: #Red ... Red language group [web-public] | ||
Pekr: 14-Sep-2012 | *Important*: Red will be distributed as a binary to end users and the effect of: red script.red will be to compile and run it from memory directly. So the -o option will become mandatory in the future for generating an executable without running it. During the bootstrapping stage, it is complex to support that feature, but it will be implementd as soon as possible. | |
Kaj: 15-Sep-2012 | Doc, the new commits are in master, not in 0.3.0, so it can't effect the problem on Syllable Server | |
BrianH: 18-Oct-2012 | Another interesting side effect of the strong separation is that it would be possible to implement the client-side of the extension interface in other languages, such as Red, so that it could use R3 extensions without changes. The REBOL portion of the extension might be trickier to implement though, because that code tends to be more tied into the actual R3 runtime model. You could write your own wrapper code if your system model is different, but the native code could be used as-is. | |
BrianH: 2-Nov-2012 | Side effect of compilation. The compiled code retrieves a value from a value slot or other indirect type, manipulates the values in typed stack or register variables, then puts the results back in the value slot or wherever. | |
Andreas: 15-Nov-2012 | In effect, we have to different notions of "first position": one used in HEAD, one used in FIRST. | |
Pekr: 22-Nov-2012 | never mind, talking about View engine itself. I don't like gobs logic in some aspects anyway ... I e.g. don't like separate gobs for text, color, image, effect, draw. Dunno low level logic, but it could be all in draw dialect. Simply put - always hated when you can do gob/text, but then you can do another text in terms of draw, ditto effect, etc. | |
Kaj: 23-Nov-2012 | With increased iterations, the effect is big in Fibonacci, but dramatic in Mandelbrot | |
DocKimbel: 16-Dec-2012 | It shouldn't have any effect on the generated code size. Can you send me the function? | |
NickA: 22-Dec-2012 | Doc, I'm very glad to see you're still working hard on Red! I was concerned that the psychological effect of everyone paying attention to R3 source, plus your own curiousity about it, might derail you for a while. I'm still eagerly awaiting every advance you make! | |
DocKimbel: 25-Dec-2012 | BREAK will probably be implemented before 2.0 (not sure for CONTINUE). So, you can't break from a loop currently. As a workaround, you can EXIT/RETURN instead. So if you write your loop in a separate function, you'll get similar effect as with BREAK. | |
DocKimbel: 9-Mar-2013 | Let me stash my changes to see if there's a side-effect. | |
DocKimbel: 12-Mar-2013 | The changes I made in the interpreter for not exiting the console on errors have a very bad side-effect: some errors are passing silently through the unit tests and are not reported! :-/ | |
DocKimbel: 16-Apr-2013 | A [catch] flag will have no effect on exceptions launched from the same level (enables re-throwing exceptions). | |
Andreas: 26-Apr-2013 | Didn't say anything to that effect, and it's not what I'm thinking either. | |
DocKimbel: 8-May-2013 | My first impressions on your proposition: 1) arr[i] is a useless syntactic addition as we already have indexed accesses: arr/i 2) #7 and #8 are going way too far from the Red/System application domain, it's basically a series abstraction. Red internal API already provides series (the internal API is not yet completed nor formalized though), so this is both unneeded and overlapping with Red standard library. What you might not realize is that you already have array-like capabilities with Red/System pointers (including structs and c-strings). If you want automatic memory management in Red/System, you won't have it, low-level programming requires a manual management of memory for accuracy and avoiding unnecessary burdens. The only array-like part that Red/System is really missing right now is the literal array-like declarations, which can be achieved without a new formal array! type. As I said earlier, adding a array! type would only add bound-checking abilities (which is a nice feature to have) and provide you with #5 as a side-effect (not very useful anyway, as array would be fixed-size). | |
DocKimbel: 8-May-2013 | The main effect is that Red/System init code is not run when the shared lib is loaded, this affects floating point exceptions flags and runtime error catching routines. Not a problem for now. | |
Arnold: 16-Jun-2013 | Thanks for the compliment Doc, not really sure what you mean exactly by making it more like Red/System and less C: use more descriptive names? I will take a closer look at some ed/System examples out there. Thanks Kaj for finding those and for the tips, the size of MM makes it the same in effect in this case, but it has to be <= then. Program not crashing, I was lucky then! off-by-one errors? My index goes from 1 up, where in C it is from 0 up, I had to debug this to make sure elements were swapped in the same way as in the original program. That is also why I declare KKP and LLP to as to save from adding 1 to KK and LL over and over again. Knuth's algorythm was the first one I found, and I knew already of its existence, so it made sense to use what you have. Sure my Red/System code is not optimised. Going to work on it now and tomorrow, and later I take on the Twister. It is a good exercise! | |
DocKimbel: 20-Jun-2013 | I suspect that if I do ptr: ran_arr_buf and I progress ran_arr_buf by 1 that I progress ptr too. That's a wrong assumption. Those two variables are distincts, so each one has its own memory slot. If you change one, that has no effect on the other. What is shared there is the pointed memory region. So, if you change ran_arr_buf/value, that will affect ptr/value (they both point to the same memory location). | |
Arnold: 20-Jun-2013 | Oh nice effect. array1: 1 2 3 4 5 m: 2 ;;print array/m ;; 2 array1: array1 + 2 ;;print array/m ;; 5 it is tricky to move the array pointer around, beware of the dog ;) | |
DocKimbel: 19-Jul-2013 | Red/System is a dialect of Red meant to address specific needs. You should see it as a feature of Red, even if it can be used alone (which is kind of side-effect of starting Red project by building R/S first). | |

Arnold: 18-Jul-2012 | MaxV: radiobuttons are best used with true and false in stead of on and of like in some documentation mentioned. The true and false I just tried out of frustration and I discovered it worked. Undocumented. Same with the block after a text or label to make the label clickable like a button. VID has an effect and a draw that could be better documented. | |
Andreas: 26-Sep-2012 | There is no single truth here. There are a few realistically defensible positions, all of which have been argued extensively before. The legal opinion of the FSF (publisher of the GPL) is pretty clear, by analogy to Perl or Java: all/most REBOL mezzanines are library functions to which a user script dynamically links. If the mezzanines are GPL licensed, the source to user scripts will have to be provided in a GPL compatible way. Equally clear is e.g. Lawrence Rosen (IP lawyer) in articulating his legal opinion. Paraphrased: "linking is irrelevant for deciding wether the result is a derivative work" -- this mostly matches Ladislav's stance. The whole point of this debate is not really ultimately deciding the resolution for that issue as pertaining to a GPL'd REBOL, but pointing out that, without additional clarification, the GPL results in a problematic legal uncertainty. This legal uncertainty may lead to quite the opposite effect of what many believe Carl actually intends. So one very easy solution, is to include a few definitive clarifications along with the GPL. Another, probably much easier, solution would be to simply sidestep this issue and use a different license. | |
BrianH: 27-Sep-2012 | Using R3 natives can have that effect as well if they're not declared to be part of the interpreter. | |
Kaj: 21-Jan-2013 | Sqlab, do you have Fossil in the same directory as download.r? The script changes directories, so on Windows when Fossil is not really installed, this could have the effect of not finding it | |
sqlab: 26-Feb-2013 | Kaj, I deleted all files and subvols created by fossil and run download.r again. The probem is not only with executable files, but with all files simple as containing just "Hello". write %test.txt "Hello" has the same effect. | |
Kaj: 26-Feb-2013 | What effect with write %test.txt "Hello" do you mean | |

BrianH: 9-May-2012 | It's internal, exported as a side effect of it being an action, used as part of path evaluation. Don't use it. | |
Henrik: 10-May-2012 | Perhaps it helps to learn about the mechanisms: There are several ways to generate a dynamic UI: The LAYOUT function works by creating an object tree, a tree of faces that are simply ordinary objects. When passing this to the VIEW function, a layout is displayed. The layout function is part of VID and is as such a high level function. VIEW is a low level function to interpret the face tree. The face tree consists of objects that contain other objects through the FACE/PANE word. If the FACE/PANE contains an object, that object is a single face, that is displayed inside the parent face. If the PANE contains a block, that block may contain multiple objects that are simply multiple faces. As such, a typical window is a face with a FACE/PANE that is a block that contains other objects. Graphically, the face is represented by a region on the screen that has the size and offset, possibly an effect, such as coloring, blur or mirroring or a text attached to it, and image or other faces that are only visible inside that region. A window is also a face. To navigate to the parent face from a face, use the FACE&/PARENT-FACE word. Note that FACE/PARENT-FACE is many times not set by VID, which is sometimes problematic. You can manipulate the face tree by adding removing objects dynamically and calling the SHOW function. You can also change values in existing face objects in the tree, such as for resizing or moving the faces and then calling SHOW again. You can also build a face tree entirely by hand, and this is usually the starting point for different layout engines, such as RebGUI, that simply build face trees in their own way. The prototype face is FACE, which is a minimum requirement face for the View engine. The prototype face for a VID face, which contains a few more words, is SYSTEM/VIEW/VID/VID-FACE, which is the minimum requirement face for VID. One condition for the face tree is to not use the same object in multiple locations. The VIEW or SHOW function will return an error if that is the case. A simpler way is also to generate a new face tree every time you want to change the layout. Although this is slightly more computationally heavy, it allows you to manipulate the block that was passed to the LAYOUT function instead of manipulating the face tree directly. This technique is best used, when the face tree changes dramatically by each manipulation. Another important concept is the DRAW engine which is a separate entity in REBOL2. It can be called to draw on an image bitmap, using the DRAW function or as in effect for a face object, by adding a parameter in the VID dialect block or by changing the FACE/EFFECT word. DRAW is used by calling a dialect. if you just want to use fields, buttons and simple user interface designs, you may not need to use DRAW. | |
Arnold: 7-Jul-2012 | Hi Chris! Thank you. I consulted this site also. But there is better news to this! In stead of the words on and of you have to use the words true and false and the problems are solved! Didn't even have to initialize the /data fields between creating the layout and calling it in action with view. Not documented but stil possible. (Like it is also undocumented on the REBOL site that you can have a checkbox followed by an action block.And this is also possible on text-labels making them clickable and have an mouse-over effect.) | |
Arnold: 26-Jul-2012 | In the script display-chess-board.r on rebol.org there is this part ;; counter is now an image - note the 'key effect ;; user to make the black in the image transparent. ;; ------------------------------------------------ counter: box 30x30 effect [key 0.0.0 oval] This does not work, when keyword merge is added the middle part is transparent when the tuple is replaced with an integer, but only the other way around or the oval is limiting the working of merge to the inside of the circle? | |
Henrik: 12-Oct-2012 | not even needed. you may DO the same script several times for the same effect. | |
Cyphre: 20-Dec-2012 | Henrik, I don't know how hard is to add gradient on line but you can 'emulate' it using textures. See this R2 example: g: draw 100x10 [pen none fill-pen linear 0x0 0 100 0 1 1 red green blue yellow box 0x0 100x10] view layout [origin 0 box 300x300 black effect [draw [pen g spline 0x0 100x100 200x30 300x300 16]]] | |

Andreas: 26-Dec-2012 | Such an app can bring up a GUI, yes. However, it will always pop up a console window (which can be closed immediately, but this will result in the "console flashing" effect some dislike). | |
Kaj: 26-Dec-2012 | Brian, I build the Red examples in both modes, so you can try out the effect if you want. MSDOS/console programs can open a window, but Windows/GUI apps don't seem to be capable of using stdout, at least not to a console they're started from | |
BrianH: 19-Jan-2013 | As for that blog, the behavior described there has some practical problems. There is nothing in the code itself (I mean the example code in the blog, not the implementation code) to indicate that 'last-stock is a free variable, but 'if and 'not are not - they are all words not declared at the top level of the module (by using them as set-words, like in an object) or elsewhere in the code. This means that if you want it to have 'last-stock be made local to a module, you would have to make 'if and 'not local as well. That works if lib words can only be set once, but not if they can be reset, since changes wouldn't propagate to the other modules or user scripts (since those values are copied to words in other contexts). We determined that the behavior described in that blog could be useful enough to be worth supporting, but had some nasty side effects that made it not be what we wanted to do by default. That is why we made it an option, in particular the isolate option. If you specify the isolate option, your module acts like it does in the blog, and this has the effect of isolating your module from all external changes to the lib context. | |
BrianH: 21-Jan-2013 | Regular modules have names and versions so they can be loaded only once, and upgraded in place if need be. As a side effect, this makes the module's context effectively global. We have a few built-in global contexts, but we don't necessarily have to make built-in global contexts for stuff that is managed by modules because the module contexts are themselves global. | |
BrianH: 21-Jan-2013 | Private modules were a side effect of the module name being optional. If a module doesn't have a name, you can't check for whether it is already loaded, so you have to load it again every time it is requested. The module itself can't even tell if it was loaded before, so it can't know whether it needs to resolve conflicts between itself and other instances of itself. That makes it basically unsafe to have an unnamed module export to lib. So instead, we skip the lib middleman and import those exports directly into the target module or user context, which makes the unnamed module effectively owned by that target, a "private" module. We found this facility useful enough that we added an explicit option to make it private (options: [private]). That makes it possible to have a named private module, which has some interesting abilities just from having a name. Having a name means that you can have the module load only once, and being private means that if you want to use its exports you have to import the module explicitly, so combined it means an explicitly accessed module that can share resources with other targets that also explicitly import the same module. | |
Ladislav: 11-Feb-2013 | Adrian, I wrote the Bindology article. There are differences in the behaviour as you noticed, some of them are quite minor (like the latter you mentioned), some may have a more noticeable effect. In the future, some revision of the article to adjust it for R3 will be needed. | |
Andreas: 1-Apr-2013 | In effect, that is :) | |

Cyphre: 21-Dec-2012 | From the "design architecture" POV we should focus on stabilizing the GOB abstraction mechanism and DRAW/TEXT/EFFECT dialects syntaxes. If these layers are fine-tuned you have great base that allows us make experiments at the low-level graphics and also as well at the high-level GUI abstraction layer. | |
Robert: 25-Dec-2012 | I think the first thing to look at is the structu sizes. Either press it back to fit 32bit size, or expand it into 64bit space. Not sure what kind of side-effect this will have. |

Ladislav: 7-Jan-2005 | your trouble is, that the evaluation of X doesn't have the same effect as if you replace X by its value. The evaluation of X only yields a set-word instead of setting anything. If you really want to set a word 'y, then there are two ways: set x 'z do compose [(x) 'z] | |

Ammon: 10-Dec-2005 | I don't want to "probe system" after a while, if you wait long enough, then it will print out but I thought that there were some optimizations made to make "probe system" start printing sooner or something to that effect. It's not "probe system" that I'm interested in. What I'm interested in is finding the conversations that I participated in several years ago on the REBOL ML concerning the problems with "probe system" but none of the search engines I used could produce them. | |

Sunanda: 2-Jun-2007 | REBOL.org looks like it is down right now -- the whole ISP who host it seem dead too. (they've not been as reliable since they merged with another ISP). Apolgies! This has no effect on REBOL.com or REBOL.net .... they are completely separate. | |
PeterWood: 14-Mar-2009 | At the moment, I'd be worried about standarising the Library on utf-8 as the effect of multibyte characters would have during script and mail processing is not understood. It could well be that the system handles multibyte characters without a hitch but nobody knows yet. I have started to write some scripts to try to help move to a consistent character encoding of the Library data but, due to time constraints, I have been very slow. | |

Vincent: 4-Mar-2005 | just a detail: in facets document, /span datatype is pair! . you could use it to store other data, but if you set a pair! to /span, /view will use it as virtual size for face (it still works in later betas, so one should be careful to not use it to store coordinates) ie: f: layout [ banner "Testing /span" guide box 400x400 effect [gradient 1x1 0.0.0 255.255.255] button "Hello!" return text-list data ["just" "a" "list"] image logo.gif logo.gif/size * 2 ] f/span: f/size ; here we tells /view to use virtual coordinates for all subfaces view/options f 'resize ; will give a fully resizable window (widgets included), but it only works for reducing window's size. | |
Ashley: 5-Mar-2005 | Good diagnosis. I knew assigning a pair! to span did *something*, I could never quantify exactly what though.

Ashley: 11-Mar-2005 | Pekr: "What is the concrete plan, if any?" ... shadwolf was on the mark. 1) Create a set of base widgets with the desired *functionality* 2) Select a look & feel to approximate 3) Apply this look & feel *consistently* to all base widgets Vincent is correct when he says we should discuss this sooner than later as look & feel can effect how a particular widget is implemented. As an example, a 'button widget trying to mimic WinXP might use multiple images and / or effects to mimic the various states a WinXP button can be in; while a minimalistic approach might just make use of 'edge and 'effect to toggle between several states. I'm leaning towards a minimalistic yet modern look & feel (perhaps even PDA-like) so put any useful links / comments / opinions / designs here for folks to look at.

Chris: 3-Apr-2005 | OT: the problem with AGG AA on smaller glyphs (not just arrow) is that it tends to have an adverse effect on glyph weight. 'course it beats bitmaps when it comes to scaling, but even pre-AA Draw gave more precise control -- hence the deterioration of the Arrow glyph post-AGG. Illustrated here: http://www.ross-gill.com/r/chevron-test.png | |

shadwolf: 1-May-2005 | mutch faster but more code and a strange effect ;) | |
Brock: 1-May-2005 | I do agree, strange effect for sure. | |
shadwolf: 1-May-2005 | maybe Ashley will make an effect draw line on the current mouse position ;) | |
shadwolf: 1-May-2005 | this is can be similate by over drawing a line with effect draw ;) | |
shadwolf: 1-May-2005 | last thing to do is to draw a vertical line with effect draw at position of the mouse | |
Robert: 1-May-2005 | line-selection: - How about using a TINT effect for images in the selected line? - Changing the state of the select box in column 2 isn't reflected in listview/picked output | |
Group: XML ... xml related conversations [web-public] | ||
Sunanda: 1-Nov-2005 | Carl has talked several times about a binary format for saving REBOL structures (can't find any references off-hand). That would probably solve this problem as what is saved is, in effect. the internal in-memory format: useless for non-REBOL data exchange and perhaps dangerous for cross-REBOL releases data exchange, but much much faster as it'd avoid most of the parse and load that REBOL does now. | |
BrianH: 24-Jun-2009 | Every MAKE object! takes a spec block that is an init function, in effect. | |
Maxim: 24-Jun-2009 | you can just do a mold/all load, that will in effect copy the whole tree along with all the series too. | |

Rebolek: 6-Dec-2005 | In Carl's blog is written "More than 50 RAMBO tickets have been implemented or fixed." so there's at least ten more fixed bugs and convolve effect has been added, so there are some new features (or at least one :) | |
Gabriele: 11-Dec-2005 | Q: (note - my view may be influenced by insufficient knowledge in the area given) - last weeks I played with wrapping some Win32 functions. I started discussion on dll.so channel, to ask developers, if they would enhance interfacing to C libraries in some way, and there was few ideas appearing. We currently have also rather strange callbacks support (limited to 16) and I would like to ask, taking into account that DLL interface in Rebol was not changed/enhanced since it appeared long time ago, if RT sees any area in which it could be made more robust, developers friendly etc.? A: We are planning to do a lot more on DLLs. In fact, future versions of REBOL will expand on the way DLLs are used in REBOL. For example, I would like to see DLL support for media loaders and savers, so if we do not directly support a specific type of media file (say, TIFF) then an external DLL can be provided to load it. There are a few other DLL related features down the road, but it is still a bit early to talk about them. Q: I realize that the open sourcing of the viewtop wasn't that successful, but do you still intend to keep releasing newer versions of it? AFAIK the current release is over a year old. I've experienced a lot of obvious bugs in the viewtop editor, which I think can easily be solved by people outside RT. A: yes we will continue to release newer versions. View 1.3.2 fixed a number of bugs in the Viewtop editor that were listed in on RAMBO. Any fixes and enhancements from the community are greatly appreciated (by everyone, not only RT!) You can post them to RAMBO, and we will review and include them (if they look good). Q: While reviewing the action! functions, I noticed the path action. The doc comment says "Path selection.". The parameters aren't typed. Does anyone know what this action does, and how to use it? Or whether it can be or should be called directly at all? A: the PATH action is what the interpreter uses to evaluate VALUE/selector expressions for each datatype. It is an internal action and has no external purpose in programs. These kinds of words often appear as a sort of "side-effect" from how REBOL is structured. Datatypes are implemented as a sort of object class, where the interpreter "sends messages" to the class to evaluate expressions. The PATH action is a message that tells the datatype to perform a pick-like or poke-like internal function. Q: Is rebcode going to support paths and/or some kind of binding? A: Certain rebcode can support anything we feel is important to put into it, but note: many things we add could slow it down, by a lot. For example, if we were to allow paths as variables, I estimate that rebcode would be about two times slower than it is now. Perhaps one way to solve this issue is for you to use COMPOSE prior to specifying your rebcode body. Within the compose, you can use IN object 'word to "pre-compute" the context references for words. For example: add.i (in object 'num) 10 Your question about binding is not clear to me. Rebcode already supports binding. Your rebcode can be part of an object context, and rebcode function words are bound to the code context. (Perhaps you are referring to an older bug that has since been fixed?) Q: What do you think about http://mail.rebol.net/maillist/msgs/39493.html ? Why not say a word in your blog, if you think that it's interessant for rebol developpment, and if you want to contact them ? A: Recently, I had the chance to sit down and talk with one of the main people from the One Laptop Per Child project (he is a friend of mine from Apple Computer days). The project has an interesting goal, but there are also many difficult issues around it (not just in the technical side, but also on the social and cultural sides). My current understanding is that the target software is Smalltalk based. Yes, it would be very interesting to allow REBOL on that system, but if you look at the list of principals for the project, you will see that such a revolution is unlikely. Is it possible that perhaps REBOL could provide some additional capability in the future? I think so. We have some special plans that I think will bring REBOL to platforms like that in the future. But, this is too early to say more. Q: 1. What is fixed/added in 2.6.2/1.3.2 (change-log, please) ? 2. What is planned for 1.4.0 (rebcode, rebservices, rich-text, RIF, and last but not least, fixed sound ...) ? 3. When can we expect 1.4.0 ? Thanks. A: 1. Gregg is preparing a summary. The document should be available this week. 2. We are evaluating a large variety of changes in REBOL, more than even the 1.4 release that we've talked about. I hope to be able to say more about these plans soon. | |

Ashley: 10-Jan-2006 | Graham, yes. Reichart, the price comparison is: Mac mini 1.25GHz with 40GB Combo drive and 512MB RAM: AU$799 Mini-ITX equivalent: VIA EPIA-TC10000 (DC-DC onboard): AU$229 OEM 40GB 2.5” 5400rpm HDD: AU$100 OEM Slimline CD/DVD combo drive: AU$140 512MB DDR333 SO-DIMM: AU$81 Mini-ITX case (difficult to source): ~AU$150 Cabling: ~AU$10 Power supply brick: ~AU$15 which comes to AU$725 (wholesale), and excludes: Software DVI output Packaging Assembly Look at other folks who are trying to do the same thing (with an emphasis on small and quiet): http://www.hushtechnologies.com/(starting at about 750 Euro (AU$1200)) http://www.theregister.co.uk/2005/12/01/evesham_aopen_minipc_win/ ($499 pounds, so about AU$1,200 for me) The Mac mini, for this class of device, wins hands down – even if you purchase it as a Linux or Windows (when re-released as an Intel Mac mini) box. It's smaller, quieter, cheaper, and more compatible (USB2, Firewire and DVI out of the box; and includes a DVI-Analog converter for PC folks still living in the 80's). What's also telling is the noticeable increase in the number of folks asking me, “does your software run on Mac”, since its introduction – but this might also be the iPod halo effect at work. Regardless, I see a lot of them around these days and the general consensus is that “they're cheap” - and this from the Dell generation who only care about price! ;) | |

[unknown: 9]: 3-Jun-2007 | Great start. Feedback - Allow full screen: Stretch to fit. - Start with larger tiles (some of us are old) - Tiles need to be much brighter and higher contrast (yes I know I can change this myself). - 3D effect should center single point perspective, not isometric. - Score? - Seed value? - Help? (shortcuts, etc.) - Undo? - Timer? - When there are no more moves, you should be notified. | |
ICarii: 28-Jun-2007 | ahh - forest and cave are from stock photos and the blue is a geometric effect | |
[unknown: 9]: 30-Jun-2007 | You are going to want to have the ability to "highlight" things. Which means one of two things. The art needs to be bigger to begin with, for example to have a highlight or glow, or you need to add the glow or effect afterwards. So for example, when the cards are on the board, they are normal, when a card lifts off the board, it should be highlighted in some way. It is a simple and subtle trick that will bring the board to life, and give it depth. | |
