Henrik: 4-Oct-2012 | As long as I don't have to tug the IDE around, then it all sounds great. :-) Sometimes you just want to spend 10 seconds installing Red and then quickly run a script, just like REBOL. | |
DocKimbel: 6-Nov-2012 | AdrianS: the output of the lexer is nested blocks of Red values, same as REBOL with its own lexer (LOAD). The AST is not stored anywhere, AST nodes are created and consumed on the fly during the compilation. So the closest thing to an AST you can get currently is the output of the lexer. For the needs of a code editor, maybe you could just invoke it on the currently edited line (though you would need to deal with unmatched opening/closing delimiters). I haven't yet though how I will achieve it in Red IDE. | |
Gregg: 30-Nov-2012 | I agree with Henrik 90%. The hard part is picking the target app and important elements. A game, or modern app with animation elements is a very different target than an "efficiency above all" business app. One of my failed attempts with REBOL was to get Carl, for just this reason, to identify a target audience. It guides your design. In the case of a Red/REBOL GUI, maybe there is no single design or dialect. Making small apps simple is hard to match to the needs of complex apps. If you're writing database/CRUD apps, wouldn't it be great to have a toolset designed just for that? That same toolset won't work well for games though. I think using an IDE as the first target app is a *fantastic* idea. It covers a lot of areas, including the possibility of building on an extensible app framework (something lighter than Eclipse :-), files, documents, workflow, tool integration, customization, and many UI elements. And *we*, developers, are the target audience. | |

MaxV: 25-Jul-2012 | I just released Rebol IDE v.5: http://rebol2.blogspot.it/2012/07/ide.html send your comments and suggestions | |
Kaj: 11-Mar-2013 | I updated our Redsite for the latest Red features, specifically runtime function creation in the interpreter (which executes the Redpages): http://red.esperconsultancy.nl/index.red I added a simple IDE example to the list of apps: http://red.esperconsultancy.nl/examples/IDE.red It's a cross between the standalone GTK-IDE example and Try REBOL; basically Try Red written in Red itself. There are two main areas: one for editing your code and one for showing the result. Since it runs on your computer, unlike Try REBOL, it keeps state between execution of code snippets. To browse the site and the apps you need the latest binary version of the GTK-browser. See above. | |

Group: !REBOL3 ... General discussion about REBOL 3 [web-public] | ||
PeterWood: 28-Feb-2013 | The LiveCode KickStarter campaign to first re-structure the code, make it easy to accpept contributions, build a new IDE and some modernisation has raised over 500,000 GBP (more than 750,000 USD). Same Carl didn't try something along those lines before releasing REBOL 3. | |
BrianH: 28-Feb-2013 | It's actually pretty easy to see how they managed it. It was: - A multi-language IDE (not a programming language, people already get those for free) - With a GUI with an emphasis on modern graphic design (pretty!) - With a fancy demo (more pretty!) - With an initial focus on programming languages and development platforms that are already popular (built-in customer base) Powerful IDEs are some of the only development tools that people are still willing to pay money for (i.e. Visual Studio). Most people can't choose what language they write in, but they more often can choose their IDE. And for crappy-but-IDE-friendly languages, an IDE can make all the difference in your productivity. They're not as helpful for really powerful extensible languages like Rebol or Perl, unless the language is so bad that just about anything would help (Perl). Plus, since an IDE is an end-user app you can afford to GPL it, since the only stuff built on it are add-ons - that doesn't work for programming languages unless they have a clear distinction between user code and built-in code that is distinct enough to not violate the GPL distinctions, because most of the competition is permissive - and without the GPL restrictions there is nothing to sell, so there is no business model to get a return on investment. It's nice to point to other open source projects and say "See! We could have done that!" but unless those are comparable projects their success isn't comparable either. | |
Scot: 28-Feb-2013 | As good as REBOL is it could use a good IDE environment. AmigaVision comes to mind. I would be interested to see whether some large chunks of change were invested to put them over the top. Right now R3 needs a message. What makes it special and valuable. What vision does it conjure up. | |
Scot: 28-Feb-2013 | I think eduction is a great market for REBOL. Net Logo actually did well in education. If Education is the goal a great IDE is the place to start. Something like a high quality layout.r or AmigaVision. |

RobertS: 1-Apr-2008 | Diss'ing IDE's might alienate some Smalltalk folk. I cannot imagine maintaining an application suite such as I deal with everyday without an IDE. I just wish it was not eclipse ... Of course only wimps used a Disk Operating System and real men code in machine codes only ... and real pro's dictated their SNOBOL punch cards to lovely assistants ... and ANT scripts are for sissies. Some must have ridiculed Tcl, Expect and TK in their day ... but if my IDE can facilitate my efforts to systematically (key word there) shrirnk company''s codebase as it becomes more reliable with better test coverage then maybe a refactoring browser would be a good tool after all. Even better if it is an integrated part of the IDE, as in Dolphin Smalltalk or Squeak Smalltalk or Smalltalk/X or Cincom Visual Smalltalk. Not that I couldn't survive on grep and diff's. But once the codebase is too large for any one person to author or maintain on their lonesome, a tool that remebers what you did last and where can be a god-send. If you want to know hell without an IDE join an actuarial department working in APL. There you don't even know if they have talent: you just hope most of it works as each quarter rolls around and try to survive year-end. But you know they're smart, cuz after all, they're actuaries - and look at all that APL code in all those files ... of course a few of them look back wistfully at their student days in C with Borland's decent IDE.

Whether the progress will continue depends on the feedback. ---All Rights Reserved The work is based on the documentation of REBOL View provided by REBOL Technology and its mailing list. All rights to this documentation remain the property of REBOL Technology. ---Plagiarized Examples Things are shamelessly plagiarized. There are many experts on the mailing list whose work is included here; most notably the examples from the REBOL documentation. ---Approach The approach that this document uses is to use REBOL/View/VID to demonstrate its abilities and give a visual tutorial. To enable this some changes have been made to the core %easyvid.r program from Carl Sassenrath. A scoll bar was added to the right pane because it was just too difficult to constrain the examples to the screen real estate that was available. ---Order Order The order of the items needs some work. The easyvid presentation approach today does not allow for the drilling down and expansion of an outline tree which is needed for a large amount of documentation. The preferred approach is to put a multi-level tree for navigation purposes and then allow navigation up and down the tree. ===To Do * make this a true outline tree * re-organize it better * update as requested and as possible by suggestions on AltME's REBOL world under group EasyVID * correct numerous flaws * better scrolling implementation using the updates that have been used in other examples such as Didier's %delete-email.r * allow clipping to clipboard like AltME does on a row for the source examples ===Introduction to VID With REBOL/View it's easy and quick to create your own user interfaces. The purpose of this tutorial is to teach you the basic concepts or REBOL/View interfaces in about 20 minutes. VID is REBOL's Visual Interface Dialect. A dialect is an extension of the REBOL language that makes it easier to express or describe information, actions, or interfaces. VID is a dialect that provides a powerful method of describing user interfaces. VID is simple to learn and provides a smooth learning curve from basic user interfaces to sophisticated distributed computing applications. ---Creating VID Interfaces VID interfaces are written in plain text. You can use any text editor to create and edit your VID script. Save your script as a text file, and run it with REBOL/View. !Note: Using a word processor like Word or Wordpad is not recommended because files are not normally saved as text. If you use a word processor, be sure to save the output file as text, not as a document (.doc) file. Recommendation: Look at TextPad from http://www.textpad.com ===Minimal VID Example Here is a minimal VID example. It creates a window that displays a short text message. Only one line of code is required: view layout [text "Hello REBOL World!"] You can type this line at the REBOL console prompt, or save it in a text file and run it with REBOL. If you save it as a file, the script will also need a REBOL header. The header tells REBOL that the file contains a script. Here is an example of the script file with a header: REBOL [Title: "Example VID Script"] view layout [text "VID Example!"] You can also add buttons and other gadgets to the script. The example below displays a text, list of files, and a button: view layout [ h2 "File List:" text-list data read %. button "Great!" ] !Click on the examples above to see how they will appear on your screen. Click on their close box to remove them. All of the examples that follow can be viewed this way. ===Window Management The code that displays the examples also shows how to manage the number of windows that are open. Look at the show-example block in the code near the end of this script. The location of the example window is also managed here by keeping track of the co-ordinates for the sample. After the sample window is moved, the next use will open at the same location. ===Pre-loaded Images For this script, the image which represented a Portable Network Graphic definition of an image is held in the script and loaded. For a small number of graphics, this can achieve some packaging and performance benefits. The image "polished" is used through the script to achieve the polished steel look that is one the outer frame. backtile polished orange button 200x50 "Polished Steel Look" polished ===Two Basic Functions Two functions are used to create graphical user interfaces in REBOL: VIEW and LAYOUT. The LAYOUT function creates a set of graphical objects. These objects are called faces. You describe faces with words and values that are put into a block and passed to the LAYOUT function. The VIEW function displays faces that were previously created by LAYOUT. The example below shows how the result of the LAYOUT function is passed to the VIEW function, and the interface is displayed. view layout [ text "Layout passes its result to View for display." button "Ok" ] Click on the above example to view it. !Note: the block provided to a layout is not normal REBOL code, it is a dialect of REBOL. Using a dialect makes it much easier to express user interfaces. ===Styles Styles describe faces. The examples above use the text and button styles to specify a text line and a button. REBOL has 40 predefined face styles. You can also create your own custom styles. Here are a few example styles: view layout [ h1 "Style Examples" box brick 240x2 vtext bold "There are 40 styles built into REBOL." button "Great" toggle "Press" "Down" rotary "Click" "Several" "Times" choice "Choose" "Multiple" "Items" text-list 120x80 "this is" "a list" "of text" across check radio radio led arrow below field "Text Entry" ] The words like backdrop, banner, box, text, and button are styles. ===Facets Facets let you modify a style. For instance, you can change the color, size, text, font, image, edge, background, special effects, and many other facets of a style. Facets follow the style name. Here is an example that shows how you modify the text style to be bold and navy blue: view layout [txt bold navy "Facets are easy to use."] The words bold and navy are not styles. They are facets that modify a style. Facets can appear in any order so you don't have to remember which goes first. For example, the line above could be written as: view layout [txt "Facets are easy to use." navy bold] Many facets that can be specified. Here is an example that creates bold red text centered in a black box. view layout [txt 300 bold red black center "Red Text"] You can create facets that produce special effects, such as a gradient colored backdrop behind the text: view layout [ vtext bold "Wild Thing" effect [gradient 200.0.0 0.0.200] ] ===Custom Styles Custom styles are shortcuts that save time. When you define a custom style, the facets you need go into the new style. This reduces what you need to specify each time you use the style, and it allows you to modify the look of your interface by changing the style definitions. For example, here is a layout that defines a style for red buttons. The style word defines the new style, followed by the old style name and its facets. view layout [ style red-btn button red text "Testing red button style:" red-btn "Test" red-btn "Red" ] So, if you wanted to create a text style for big, bold, underlined, yellow, typewriter text: view layout [ style yell tt 220 bold underline yellow font-size 16 yell "Hello" yell "This is big old text." yell "Goodbye" ] ===Master Stylesheet REBOL holds its styles in a master stylesheet. When you are sure that you want to share them without having to add the style sheet line then do it as follows: First add the style to the master sheet: button 200x50 "Define text-note as maroon bold text" [stylize/master [ text-note: txt maroon bold ]] button 200x50 "Define text-note as white italic text" [stylize/master [ text-note: txt white italic ]] Then invoke it: view layout [ across size 200x200 return text-note "This shows a master stylesheet style in use." return text-note "This shows another usage of the same style." return text-note "If you want to see the other style displayed, click the Add Style section again and then use the other button" ] ===Note About Examples !From this point forward, all examples will assume that the view and layout functions are provided. Only the layout block contents will be shown. To use these examples in your scripts, you will need to put them in a layout block, as was shown earlier. For example, code that is written as: view layout [button red "Test it"] will now appear as: button red "Test it" ===Face Sizes The size of a face depends on its style. Most styles, such as buttons, toggles, boxes, checks, text-lists, and fields, have a convenient default size. Here are some examples. button "Button" toggle "Toggle" box blue field text-list If no size is given, text will automatically compute its size, and images will use whatever their source size is: text "Short text line" text "This is a much longer line of text than that above." image %palms.jpg You can change the size of any face by providing a size facet. The size can be an integer or a pair. An integer specifies the width of the face. A pair specifies both width and height. Images will be stretched to fit the size. button 200 "Big Button" button 200x100 "Huge Button" image %palms.jpg 50x50 image %palms.jpg 150x50 ===Color Facets Most styles have a default color. For example the body of buttons will default to a teal color. To modify the color of a face, provide a color facet: button blue "Blue Button" h2 red "Red Heading" image %palms.jpg orange Colors can also be specifed as tuples. Each tuple contains three numbers: the red, green, and blue components of the color. Each component can range from 0 to 255. For example: button 200.0.200 "Red + Blue = Magenta" 200 image %palms.jpg 0.200.200 "Green + Blue" Some face styles also allow more than one color. The effect of the color depends on the style. For text styles the first color will be used for the text and the second color for the background of the text: txt "Yellow on red background" yellow red banner "White on Navy Blue" white navy For other styles, the body of the face is the first color, and the second color will be used as its alternate. button "Multicolor" olive red toggle "Multicolor" blue orange ===Layout Commands To drop user interface elements on the canvas according to VIDs directional layout controls ---Across You are placing elements in a row orientation across return button "A" button "B" button "C" return button "D" button "E" button "F" ---Below You are placing elements in a column orientation below return button "A" button "B" button "C" return button "D" button "E" button "F" ---Mix You can mix the directional controls across return button "A" button "B" below button "C" across button "D" button "E" button "F" ---Padding The pad keyword creates extra padding between styles. It uses a pair or integer value. When it is an integer, spacing is created either horizontally (across) or vertically (below). When it is a pair, the spacing will be created both horizontal and vertically. The following example illustrates both uses. First, the buttons "one" and "two" are padded with an integer representing 40 pixels in one direction. Then the buttons "three" and "four" are padded with a pair representing 40x40 pixels. across button "one" pad 40 button "two" return button "three" pad 40x40 button "four" Padding can be negative. backtile polished orange pad 200x200 button "A" pad -100x-100 button "B" ---Guide A guide is a virtual alignment control title "Buttons Without A Guide" button "one" button "two" return button "three" button "four" return button" five" button "six" With an implicit guide location title "Buttons With An Implicit Guide Location" guide button "one" button "two" return button "three" button "four" return button" five" button "six" With an explicit guide location across title "Buttons With An Explicit Guide Location" guide 55x100 button "one" button "two" return button "three" button "four" return button" five" button "six" ===Tabstops Tabs can be used for alignment. ---Across tabs 200 ; sets tabs every 200 pixels across button 20 "A" tab button 20 "B" tab button 20 "C" tabs 100 ; sets tabs every 100 pixels return button 20 "D" tab button 20 "E" tab button 20 "F" ---Below tabs 200 ; sets tabs every 200 pixels below button 20 "A" tab button 20 "B" tab button 20 "C" tabs 100 ; sets tabs every 100 pixels return button 20 "D" tab button 20 "E" tab button 20 "F" ---Explicit Settings Tabstops can be set at explicit values tabs [100 124 166 212 300] across tab button 20 "A" tab button 20 "B" tab button 20 "C" tab button 20 "D" ===Color Facets Most styles have a default color. For example the body of buttons will default to a teal color. To modify the color of a face, provide a color facet: button 200 blue "Blue Button" h2 red "Red Heading" image polished orange Colors can also be specifed as tuples. Each tuple contains three numbers: the red, green, and blue components of the color. Each component can range from 0 to 255. For example: button 200.0.200 "Red + Blue = Magenta" 200 image polished 0.200.200 "Green + Blue" Some face styles also allow more than one color. The effect of the color depends on the style. For text styles the first color will be used for the text and the second color for the background of the text: txt "Yellow on red background" yellow red title "White on Navy Blue" white navy For other styles, the body of the face is the first color, and the second color will be used as its alternate. button 200 "Multicolor" olive red toggle 200 "Multicolor" blue orange From the mailing list, there was a problem reported in changing button color: view layout [ b: button "New color" [ b/color: random 255.255.255 show b ] ] And the answer was that the gradient of the color was preventing this change from working: style color-changing-button button 0.0.0 ; new style overwrites gradient effect b: color-changing-button "New color" [ b/color: random 255.255.255 show b ] ===Text Facets Most faces will accept text to be displayed. Even graphical faces can display text. For example, the box and image faces will display text if it is provided: box blue "Box Face" image polished "Image Face" Most button faces will accept more than one text string. The strings will be shown as alternates as the face is selected. button 200 "Up" "Down" toggle 200 "Off" "On" rotary 200 "Red" "Green" "Blue" "Yellow" choice 200 "Monday" "Tuesday" "Wednesday" "Thursday" "Friday" text-list 200 "Monday" "Tuesday" "Wednesday" "Thursday" "Friday" When other datatypes need to be displayed as text, use the form function to convert them first: button 250 form now field form first read %. ===Normal Text Style Normal text is light on dark and can include a number of facets to set the font, style, color, shadow, spacing, tabbing, and other attributes. text "Normal" text "Bold" bold text "Italic" italic text "Underline" underline text "Bold italic underline" bold italic underline text "Big" font-size 32 text "Serif style text" font-name font-serif text "Spaced text" font [space: 5x0] Text also includes these predefined styles: title "Title" 200 vh1 "vh1" vh2 "vh2" vh3 "vh3" vh4 "vh4" label "Label" ===Document Text Style Document text is dark on light and can also include a number of facets to set the font, style, color, shadow, spacing, tabbing, and other attributes. txt "Normal" txt "Bold" bold txt "Italic" italic txt "Underline" underline txt "Bold italic underline" bold italic underline txt "Big" font-size 32 txt "Serif style text" font-name font-serif txt "Spaced text" font [space: 5x0] Document text also includes these predefined styles: title "Centered title" 200 h1 "Heading 1" h2 "Heading 2" h3 "Heading 3" h4 "Heading 4" tt "Typewriter text" ===Text Entry Fields Text input fields accept text until the enter or tab key is pressed. A text input field can be created with: field To make the field larger or smaller, provide a width: field 30 field 300 Fields will scroll when necessary. Larger amounts of text can be entered in an area. Areas also accept an enter key and will break lines. area You can also specify the area size: area 160x200 To force the text in an area to wrap rather than scroll horizontally, provide the wrap option: area wrap ===Text Setting To set the value of a text field under program control, use /text: e.g. across backtile polished return t1: txt 200 "This is some original text" return f1: field 200 "Some field text" return a1: area {Some original area text.} wrap 200x80 return button 200 "Change Text" [ t1/text: "Some different text" f1/text: "Some new field text" a1/text: {Some wrapping text in the^/ area field to^/ show that this^/ is supported} show [t1 f1 a1] ] ===Text Lists Text lists are easy to create. Here is an example. text-list "Eureka" "Ukiah" "Mendocino" You can also provide it as a block: text-list data ["Eureka" "Ukiah" "Mendocino"] Almost any type of block can be provided. Here is a list of all the files in your current directory: text-list data read %. Here is a list of all the words REBOL has scanned: text-list data first system/words ===Scrolling Text List A style to allow maintenance of lists from Brett Handley on the REBOL list: style updatable-text-list text-list with [ update-slider: does [ sld/redrag lc / max 1 length? head lines ] ] tl: updatable-text-list 300x100 data copy system/locale/months button 300x20 "Delete first entry on the list" [ remove tl/data tl/update-slider show tl ] button 300x20 "Append the 'now' timestamp to list" [ append tl/data mold now tl/update-slider show tl ] ===Text List Picked Values list-of-letters: text-list "a" "b" "c" "d" "e" button 200 "Pick Item 3" [ clear list-of-letters/picked append list-of-letters/picked pick list-of-letters/data 3 show list-of-letters ] ===Images By default an image will be scaled to fit within a face. image 60x60 polished image polished red Images can be framed in a number of ways: image 100x100 polished frame blue 5x5 image 100x100 polished bevel image 100x100 polished ibevel 6x6 Most other faces can accept an image as well as text: box 100x100 polished button "Button" polished purple toggle "Toggle" polished blue red field bold "This is a field." polished effect [emboss tile] field bold "This is another field." polished effect [brighten 100] The image can be provided as a filename, URL, or image data. ===Backdrops A backdrop can be a color, an effect, an image, or a combination of the three. For example a backdrop color would be written as: backdrop navy title "Color Backdrop" gold To create a backdrop effect provide it on the line: backdrop effect [gradient 1x1 0.0.100 100.0.0] title "Gradient Backdrop" gold A backdrop image can be a file, URL, or image data: backdrop polished title "Image Backdrop" red The backdrop image can be colorized: size 400x500 backdrop polished blue title "Blue Image Backdrop" The image can include an effect: backdrop polished effect [fit gradcol 1x1 100.0.0 0.0.250] title "Gradient Image Backdrop" ===Backtile To make a backdrop use a tile effect there are two options: backdrop polished effect [tile] banner "This shows a backdrop with a tile effect" or backtile polished banner "This demonstrates backtile" Note the difference between: size 400x500 backdrop polished banner "Here one image is stretched to cover the canvas" and size 400x500 backtile polished banner "Here one image is repeated to cover the canvas" ===Effect Facets A range of effects are supported for faces. All of these effects are performed directly on the face when it is rendered. Here are examples of a few possible effects in top to bottom then left to right order: style polished-steel image 80x60 polished polished-steel effect [flip 1x1] polished-steel effect [rotate 90] polished-steel effect [reflect 1x1] polished-steel effect [crop 0x50 120x60 fit] polished-steel effect [grayscale] polished-steel effect [invert] polished-steel effect [difference 200.0.0] polished-steel effect [tint 80] return polished-steel effect [contrast 50] polished-steel effect [brighten 50] polished-steel effect [sharpen] polished-steel effect [blur] polished-steel effect [colorize 204.0.0] polished-steel effect [gradcol 1x1 150.0.0 0.0.150] polished-steel effect [gradmul 0x1 0.100.0] polished-steel effect [grayscale emboss] Effects can be used in combination to create other interesting results. However, keep in mind that the computations are performed in real time. If complex combinations are required, a temporary image should be created with the to-image function. ===Actions An action can be associated with almost any face. To do so, follow the face style with a block: button "Test" [alert "test"] The block is used as the body of a function that is passed the face and the current value (if the face has one). For example: toggle "Toggle" [alert form value] rotary "A" "B" "C" [alert form value] text "Click Here" [alert face/text] If a second block is provide, it is used for the alternate actions (right key): button "Click Here" [view/new layout [txt "action"]] [view/new layout [txt "alt-action"]] Use variables to modify the contents or state of other faces. For example, the slider will update the progress bar: slider 200x16 [p1/data: value show p1] p1: progress !More action on actions needed... ===Show After the state is changed for a user interface element, it must be re-drawn to be reflected on the user interface canvas. Accomplish this with the show message. backtile polished across toggle "Toggle State" [ cybernetics?/data: not cybernetics?/data show cybernetics?] return label "Are you interested in cybernetics?" cybernetics?: check One show command can be used for multiple user interface elements backtile polished orange across b1: check label "Red" return b2: check label "Green" return button 200 "Change State But No Refresh" [b1/data: not b1/data b2/data: not b2/data] return button "Show" [show [b1 b2]] ===Hide A user interface element can also be hidden. backtile polished orange across c1: check hide-button: button "Hide" [hide c1] return show-button: button "Show" [show [c1 d2]] The show-button action tries to show a user interface element 'd2' that does not exist. REBOL/View ignores these. ===Invisible Faces To make a button invisible when the view is opened, you can define an invisible button style This approach sets the show? value to false when the user interface element is initialized. across style invisible-button button with [append init [show?: false]] late-shower: invisible-button "I'm Here" return return button 200 "Show Invisible Button" [show late-shower] This works for the other visible user interface element. ===Focus A user interface element can programmatically be given the focus. across backtile polished button 200 "Set focus to Phone Field" [focus f2] return label "Name: " f1: field 100 return label "Phone: " f2: field 100 return button 200 "Remove focus from Phone Field" [unfocus f2] return button 200 "Hide the Phone Field" [hide f2] return ---Focus Defect !Note that the tab function shows a hidden field. I have assumed that this is a defect. If a field is hidden, the tab button should not make it visible. This has been previously sent to feedback. ===Radio Buttons A radio button is used to make a choice between mutually exclusive values. Your preferred programming language is REBOL or C++ or PL/1 or APL but it is only one of those. across backtile polished radio of 'programming-language pad 0x-4 label "REBOL" return radio of 'programming-language pad 0x-4 label "C++" return radio of 'programming-language pad 0x-4 label "PL/1" return radio of 'programming-language pad 0x-4 label "APL" return To mix two groups of radio buttons on one screen, associate them with their groups using the "of 'word". In the above, the grouping is 'programming-language. across backtile polished radio of 'programming-language pad 0x-4 label "Language: REBOL" return radio of 'programming-language pad 0x-4 label "Language: C++" return radio of 'editor pad 0x-4 label "Editor: TextPad" return radio of 'editor pad 0x-4 label "Editor: Notepad" return The padding in the above is needed to keep the label aligned with the radio button. across backtile polished orange radio of 'programming-language pad 0x-4 label "REBOL" return radio of 'programming-language label "APL" return ===Radio Button Settings A radio button is not very useful unless you can find out what its setting is and change that setting under program control. across backtile polished orange rebol-radio: radio of 'programming-language [programming-language: 'rebol] pad 0x-4 label "REBOL" return apl-radio: radio of 'programming-language [programming-language: 'apl] label "APL" return button 200 "Toggle radio button" [ apl-radio/data: not rebol-radio/data: not rebol-radio/data show [rebol-radio apl-radio] ] ===Check Box ---Purpose A check box is used to allow user interface choices where the choices are not mutually exclusive. across backtile polished orange c1: check label "Likes animals" return c2: check label "Like Monkees" return c3: check label "Like The Animals" ---State A check box is not much good if you can't get and set its state (on or off). across backtile polished orange c1: check label "Likes animals" return c2: check label "Like Monkees" return button "Set State" [ c1/data: true show c1 c2/data: false show c2 ] ===Sensor ---Purpose A sensor is an invisible user interface element. Using a sensor only makes sense in a few instances. If you want a keycode action where there is no visible user interface element to link the action to then a sensor can be used. This sensor code adds an Escape or Back or Enter action that will close the window. sensor 1x1 keycode [#"^M" #" " #"^(back)" #"^(ESC)"] [unview] Or if you want to make portions of an image 'hot' instead of putting buttons on top of the image, then a sensor will achieve this. across backtile polished orange txt "Click on the upper left section of the gray image to invoke the sensor action" return animage: image 100x100 polished ; here the image is just the polished area at animage/offset sensor 50x50 [alert "You pushed over the sensor"] ===Displaying Script Values If the script has a standard format headings, including custom ones, these can be used in the application by picking them from the system/script/header. backtile polished across banner "About" return text font-size 16 rejoin ["Title: " form system/script/header/title] return text font-size 16 rejoin ["Originator: " form system/script/header/author] return text font-size 16 rejoin ["Modifier: " form system/script/header/modifier] return text font-size 16 rejoin ["Version: " form system/script/header/version] return text font-size 16 rejoin ["Updated: " form system/script/header/date] return button "OK" [unview] ===Toggle A toggle button represents boolean state - either on or off. The button stays down until toggled again. Colors and text can be paired for "on" and "off" state. toggle "Up" "Down" red blue To set the state via program control, use: across backtile polished return t1: toggle "Up" "Down" red blue return button polished 204.0.0 100 "Toggle State" [ t1/state: not t1/state show t1 ] ===Rotary Buttons Rotary buttons are a different sort of user interface device. They can cause some challenges because the state is what's showing so you have to blindly "toggle" to get to a state that you want. But for quick and easy uses where the user is familiar with the options, they can be handy. If you plan to use them for a long list of items such as shown below, they might give you some usability concerns. ---Example across backtile polished rotary data ["First" "Second" "Third"] ---Setting State across backtile polished return r1: rotary data (my-options: ["First" "Second" "Third"]) return button 200 "Change Rotary State" [ r1/data: next r1/data if tail? r1/data [r1/data: head r1/data] show r1 ] ---Example - Usability For Unfamiliar List Contents The rotary button demonstrated here contains some information unfamiliar to most (Saturn's satellites). Use it to to set the state so that "Calypso" is set. Doable but without knowing the order each re-paint has to be checked to ensure that it is not "Calypso" before clicking again. If you do click past the choice that you want, there is no back function so you have to cycle through again. return rotary data [ "Pan" "Atlas" "Prometheus" "Pandora" "Epimetheus" "Janus" "Mimas" "Enceladus" "Tethys" "Telesto" "Calypso" "Dione" "Helene" "Rhea" "Titan" "Hyperion" "Iapetus" "Phoebe" ] ===Arrows REBOL/View supports arrows as simple user interface elements. Actions can be associated with them. ---Arrowheads And Actions By default, the arrow is 20x20 across size 200x100 backtile polished at 50x50 arrow left [alert "You pressed the left arrow"] [alert "You pushed the alternate button on the left arrow"] at 70x30 arrow up at 90x50 arrow right [alert "You pressed the right arrow"] at 70x70 arrow down ---Very Sharp Arrows And with a little work the arrows and boxes can be merged to look sharper. Here is a "sharp at both ends" arrow from the block diagram script by Carl: origin 0 backcolor white at 0x0 box 40x40 white effect [arrow rotate 270] at 110x0 box 40x40 white effect [arrow rotate 90] at 24x10 box black 100x20 ---Arrow Blend So that shows you how to make an arrow blend into your background size 100x100 across backdrop gray at 50x50 box 40x40 gray effect [arrow rotate 90] at 40x67 box 25x5 black ===LED LEDs would be used to display state (on or off). Clicking the LED toggles its state and changes its color. LEDs do not support alternate mouse button actions. across banner "Light Emitting Diode" return l1: led 10x10 [alert "LED left mouse action"] label "Alert status" l2: led 10x10 [alert "LED left mouse action"] label "Network status" return button "Change state" [ l1/data: not l1/data l2/data: not l2/data show [l1 l2] ] ===Box ---Boxing Draw boxes of any heigth and width with the box style box "Large Box" 200x400 polished orange ---Boxes As Lines If you make the box narrow enough or short enough it is a line (or a dot). across size 300x300 backtile polished at 50x0 box 3x100 gold at 0x50 b1: box 100x3 gold at 10x10 box 5x5 red ---Boxes Can Grow across size 300x300 backtile polished at 150x0 b1: box 100x3 gold return pad 0x100 button "Grow Down" [ for i 3 300 1 [ b1/size/y: 1 + b1/size/y wait 00:00:00.01 show b1 ] ] return pad 0x100 button "Back Up" [ for i 300 3 -1 [ b1/size/y: b1/size/y - 1 wait 00:00:00.01 show b1 ] ] You might even find a use for it. ---Grid Effect Not sure of the use for this yet but here is what you can do: return box "Grid Lock" with [effect: [grid 20x20 8x8 4x3]] white 300x200 return box "Grid Lock" with [effect: [grid 20x20 5x5 3x3]] white - 80 300x200 ===Frame Earlier versions of REBOL VID supported frames in layouts such as view layout [frame "This is the Bay" %bay.jpg] These are no longer valid. But frames can be put around some user interface devices: image 100x100 polished frame red ===List A list is an iterated sub layout and takes a layout block that uses the Visual Interface Dialect. The styles in the layout will be repeated until there is no more room to fit them within the list dimensions. ---Why A face can be iterated to create a number of virtual faces. For instance, when displaying a list of ten buttons, each of the buttons does not need to be created as a separate object. If the buttons only differ by a few facets (such as position, text, and action taken on selection), a model face can be created and iterated for its other position. This is useful when creating scrolling lists of files and other data sets that share the same appearance. ---Supply Supply provides the data to the list for an iterated face. do [cnt: 0 list-collection: [aqua sky water] ] backtile polished orange across list-displayed: list 100x72 [ origin 0 space 0x0 across color-field: txt bold 80x24 ] supply [ if none? one-color: pick list-collection count [exit] face/text: do pick [one-color] index ] return txt gold 180 "OK ... but not too useful" ---Supply Columns Maybe adding some more columns would be better. Here I'll add a column of buttons that display the color name and a column of text strings in italic. do [ cnt: 0 list-collection: [aqua sky water gold silver coffee] ] backtile polished orange across list-displayed: list 300x200 [ origin 0 space 0x0 across color-field: txt bold 80x24 color-button: button 80x24 pad 5x1 txt 100 italic ] supply [ if none? one-color: pick list-collection count [exit] face/text: do pick [ [one-color] [to-string one-color] [rejoin [" " to-string one-color]] ] index ] return txt gold 300 {A bit more interesting but the last row repeats to fill the list size. Some of the other VID components will automatically stretch to fit the size needed (such as this txt field) but the list does not behave that way. You have to make the list size fit its data or make it smaller and add a vertical scroll capability. That is shown a little later on.} ===List With Supplied Data This example is to show adding action to the list and adds a horizontal line between the rows. do [ cnt: 0 list-collection: [aqua sky water gold silver coffee] ] backtile polished orange across list-displayed: list water edge [size: 6x6 color: silver] 350x96 [ origin 0 space 0x0 across color-field: txt 60 [alert rejoin ["You pressed the " face/text " text field"]] pad 45x0 color-button: button 80 [alert rejoin ["You pressed the " face/text " button"]] pad 5x0 txt 120 italic return box 350x1 white ; this causes a horizontal line to appear between each row ] supply [ if none? one-color: pick list-collection count [exit] face/text: do pick [ [one-color] [to-string one-color] [rejoin [" " to-string one-color]] ] index ] ===Supply List With Scroll This example shows a supplied list with a scroll capability. More colors are added to demonstrate scrolling. Note that this is a verbose list of code where I added comments for my understanding of how the scroll was linked to the list. The same effect can be accomplished with fewer lines of code. do [ ; first this do block creates the data definitions needed. slider-position-clicked: 0 count: 0 x: 450 y: 300 row-y: 16 ; the row height includes the data plus any separator lines list-size: to-pair reduce [x y] ; this is the size of the display list separator-size: to-pair reduce [x 1] slider-size: to-pair reduce [24 y ] list-collection: [ aqua bar-color base-color beige black blue brick brown button-color coal coffee crimson cyan forest gold gray green ivory khaki leaf linen magenta main-color maroon mint navy oldrab olive orange over-color papaya pewter pink purple rebolor red sienna silver sky snow tan teal violet water wheat white yellow ] supply-style: stylize [ button-fixed: button left coal to-pair reduce [80 row-y] ; these keep the row elements the same height text-fixed: txt to-pair reduce [160 row-y] ] data-size: length? list-collection ] backtile polished orange ; this section layouts out the list across list-position: at ; the position is captured here in order to later put the slider beside it list-displayed: list linen edge [size: 6x6 color: tan] list-size [ origin 0 space 0x0 across styles supply-style text-fixed [alert rejoin ["You pressed the " face/text " text field"]] button-fixed [alert rejoin ["You pressed the " face/text " button"]] pad 5x0 text-fixed 80 italic [alert rejoin ["You pressed the italic " face/text " text field"]] return box separator-size gray ; this causes a horizontal line to appear between each row ] supply [ count: count + slider-position-clicked if none? one-color: pick list-collection count [exit] face/text: either count > (1 + data-size) [""] [ do pick [ [one-color] ; this is supplied to the first txt field (text-fixed) [to-string one-color] ; this is supplied to the button (button-fixed) [rejoin [" " to-string one-color " "]] ; this value is supplied to the last text-fixed field ] index ] ] ; now add a slider to the side of the list at list-position + (list-size * 1x0) ; this finds the top right border of the list widget vertical-slider: slider slider-size to-integer y / row-y [ slider-position-clicked: vertical-slider/data ; the slider has to be bound to the size of the list * ((1 + data-size) - ((y / (1 + row-y)))) ; including the row height if slider-position-clicked <> count [ count: slider-position-clicked show list-displayed ] ] ===Slider A slider is interactive user interface element. The data of a slider varies from 0 to 1. backtile polished orange across slider-1: slider 200x40 return button 200 "Move first slider to 50%" [ slider-1/data: .5 show slider-1 ] return txt 200 "The second slider in this example is initialized to the 80% mark." return slider 200x40 with [append init [data: .8]] ===Progress Indicator The progress-1 face in this example is a progress indicator. Because it is only displaying information, it is non-interactive i.e. you can not change its value by dragging its edges. The alternate button is not supported on a progress indicator. backtile polished orange across slider 200x40 [ progress-1/data: value field-1/text: join (to-integer (100 * value)) " %" show [progress-1 field-1] ] return progress-1: progress return field-1: field ===Panels Panels are used to create sub-panes that can be more easily managed by grouping the user interface devices on a panel. The first example below shows how to use panels for layout alignment. By creating a panel definition, all of the components defined within it are aligned relative to its origin. across backtile polished brick tabs 50 return panel-1: panel 250x120 [ backtile polished across return button water 200 "Button A" return button aqua 200 "Button B" return button sky 200 "Button C" ] at panel-1/offset + panel-1/size panel 60x90 [ ; start at the bottom right corner of panel-1 backtile polished across return button tan 20 "1" return button coffee 20 "2" ] ---Multiple SubPanels example This example from the REBOL html documentation shows how to easily hide and show sections of a user interface by displaying them on the face area of a box. do [ ; define two panels panel1: layout [ origin 8x8 h2 "Panel 1" field "Field 1" field "Field 2" button "The Answer" [alert "I know nothing."] ] panel2: layout [ origin 8x8 h2 "Panel 2" across txt "X:" slider 150x16 return txt "Y:" slider 150x16 return check [panel2/color: maroon show panel2] txt "Don't click this" return check [panel2/color: silver show panel2] txt "Click this" return ] panel1/offset: 0x0 panel2/offset: 0x0 ] vh2 "Subpanel Examples" ; now demonstrate panel use guide pad 20 button "Panel 1" [panels/pane: panel1 show panels] button "Panel 2" [panels/pane: panel2 show panels] button "Quit" [unview] return box 2x140 maroon return panels: box 220x140 do [panels/pane: panel1] ===Simple Default Style Override The style's default look can be overriden easily with one line of code. For example, to make the default button size 200x200 with a water color, use style button button 200x200 water button "Big Blue Button" [unview] To make the toggle some different default colors: style toggle toggle crimson sky toggle "Up" "Down" Note that these stay in effect until they are overridden so if you use the default values, exercise some care unless you meant to do that. ===Image Maker An option used by Carl in some of his programs is to let View create specific icons so that you have portability and more control of look of the image then if you referenced an external file such as gif that was a bullet display. Here's how to do that: do [ make-image: func [xy wh eff] [ eff: layout [ size 20x20 at xy box wh effect eff ] eff/color: rebolor to-image eff ] dot: make-image 6x5 9x9 [gradient 1x1 255.0.0 0.0.0 oval key 0.0.0] dot-big: make-image 8x7 12x12 [gradient 1x1 255.0.0 0.0.0 oval key 0.0.0] arr: make-image 3x3 14x14 [arrow 0.0.127 rotate 90] ard: make-image 3x3 14x14 [arrow 0.0.127 rotate 180] ] ; end of "do" - it is needed here because easyvid approach is expecting vid dialect commands banner "Presentation Points" size 400x300 across style label label gold ; make a label's text be a different color than the default return image dot label "This is bullet point number 1" return image dot label "This is bullet point number 2" return image arr label "This is arrow point number 1" return image ard label "This is an arrow making a different point" return image dot-big pad 0x4 area 300x80 wrap "And because these arrows and dots are images, action can be added to them to make them 'hot' with mouse actions including 'over'." ===Needs Some Work !More to come.

This is a slightly modified version. Here again a DO block precedes the layout code for non-layout initiatiation ... here the definition of a function. Why make a diagram this way? 1. One reason is that it can be interactive ... the sections are all "hot" with a few lines of code. Here they pop up REBOL Dialogs but they could do anything that can be coded even something as simple as launching a browser on a different URL for each diagram component. The "Compositor" box demonstrates this by launching your browser on the REBOL.com site. 2. Very small footprint size compared to other presentation source formats. do [ information: func [info [string!]][ request/ok reform [ info] ] ] style bx box 255.255.255 0.0.0 font-size 11 font [color: 0.0.0 shadow: 0x0] edge [size: 5x2] [request/ok reform ["No information on" face/text]] style bb box bold left top para [origin: 6x10] edge [size: 2x2] [request/ok reform ["No information on" face/text]] backcolor silver + 30 at 15x15 h1 486 left "Arch Structure" at 15x50 bb "Client" 506x436 160.80.80 [ information "Any client machine e.g. branch or Call Centre"] at 25x252 bb "Mid-Tier" 486x68 effect [gradient 1x1 169.91.155 80.45.75] at 25x152 bb "UI" 486x96 effect [gradient 1x1 38.156.82 19.78.41] at 25x324 bb "Servers" 486x151 effect [gradient 1x1 103.96.200 50.45.100] [ information "Mid-tiers servers with XYZ relational database server" ] at 130x216 bx "Compositor" 182x24 bold [browse http://www.rebol.com] at 130x60 bx "Browser" 120x24 [information "Branch standard browser"] at 130x188 bx "Sound" 182x24 bold [information "Sound services"] at 255x60 bx "Win32" 120x24 [information "Win32 App"] ===Column Images Creates a layout looking (a little) like columns.

Assumes you have set up your email in set-user e: field "Email" s: field "Subject" m: area "Body" btn "Send"[send/subject to-email e/text m/text s/text alert "ok"] * better yet, make your own... if the code for the basic is 1 line, then a custom version is not far away. Here's an example that allows selection of your frequent contacts (entered in the names-addresses series) and keeps a journal of email that you have sent (using this code) in file email-journal.txt. Assumes you have setup your user profile correctly to allow sending of email. do [ names-addresses: [ "Contact 1" [contact1-:-no-such-address-:-com] "Contact 2" [contact2-:-no-such-address-:-com] "Contact 3" [contact3-:-no-such-address-:-com] ] names: copy [] foreach [name address] names-addresses [append names name] journal?: false ; set to true if want to journalize sent email ] e: rotary 200 data sort names s: field "Subject" m: area 500x400 wrap "Body" btn "Send"[ send/subject who-to: select names-addresses e/text m/text s/text alert join "Sent email to: " form who-to if journal?

SteveT: 12-Jan-2008 | Perspectives of a newbie! By Steve Thornton (SteveT) Hi! everyone, as someone brand new to REBOL I've been asked to log a journal describing my experiences using REBOL. I think the first thing to get out of the way is to tell you where I'm coming to REBOL from. I've programmed on and off for over twenty years starting with Clipper 5 (dBaseII), Visual Basic (Access), C# (SQL Server), Java(NetBeans + JavaDB). I've worked in a variety contract/freelance work. I earn approx half my income form 'Thornton Software' and I work for Iris Software Group - as a training consultant (training accountants :-\ someone has to do it!) I can hear some of you saying 'Ahh! he's an IDE wimp - real men/women code from scratch'. It was strange - every language I've used had an IDE and I was a bit put off having to go find myself an editor. Until something better find's me I'm using the freebie 'CREdit' as recommended by Sunanda. The easiest way to edit/test the scripts is to open an explorer window at the side of the CREdit window showing my scripts folder. I can then drag a .r file onto the CEdit screen and it opens it. To run the script I double-click it in the explorer window. The help and documentation available is better than I have previously experienced. Some of the components I've been wow'ed by so far is Henriks List-View and RebDb from Dobeash. I've looked at RebGUI and for the time being I would prefer not to use anything on top of VID, I need to learn pure VID before using anything else. REBOL Cookbook of examples is a useful place to start. Some more form oriented examples would be cool. Example 014 - 'Open two windows' and Example 10 - 'Simple text form window' are both useful The Event Handling guide is a good resource for programmers moving from Visual Studio etc.. That's more than enough to be going on with, next time I'll cover my experiences with VID, FACES and handling Events. Bye for now. Steve Thornton | |
Gregg: 12-Jan-2008 | Good post Steve. I was an "IDE wimp" myself, having from from QuickBASIC, PDS, VB, and others. I never thought I would use a language without one, but REBOL is just that good. :-) | |

Normand: 5-Apr-2005 | will be to settle it by inverting the problem : edit text in a console or an editor, and have the console or editor to parse the text and transform it according to the commands it find in it. I did search for that. The closest library to such goal I found is either scintilla for an editor or tkcon, the adaptable tcl console. But all this suppose that we dispose of Rebol source code to put the language parser in it, right (like ion.pe)? So we would have to rely on R# (open source) instead of Rebol? Either way, it does seem that handling the problem well is pushing us out of Rebol; not a charming proposition. I am just expressing my frustration of not being able to solve a problem that is not existing in other languages. As a priority, I do think that the repositioning of the caret is the show stopper. I could live with NOT rendering in the SAME window as the editing window; I consider it a form of cosmetics. But I can hardly ask people to start edit documents in a lame editor that takes seconds to go from page 120 to 130. It would be nice if RT could find a solution to that, as it would ease the way to specialised IDE's, Ide for Rebol and the many specialised dialects. By the way, did Ammon Johnson finished to wrote his REBOL-based IDE, called RIDE? | |

Maxim: 5-Feb-2007 | liquidator, teaser here is a quick snapshot of the culmination of years of work, finally coming together. using the same (evolving and improving) core engine as the regraph tech demo, I am now attacking the IDE for dataflow application development. FINALLY. Also note that this is built over liquid which is a full featured, lazy computing, dynamically reconfigurable dataflow engine. also note that all internals of the nodes (processing and gui views) are built using liquid itself, so it will be possible to apply your own connections within the internals of the application itself ! Expect first working demos within a few weeks. First picture out of the lab: this is basically a generic "Add" node being instanced 4 times, note that each plug can stick out at any angle and that the node type label is already neatly aligned in the center of the node's core at the center. http://www.pointillistic.com/open-REBOL/moa/steel/images/news/liquidator.jpg all lines and plugs stay connected whatever you drag around (plug or node) | |

eFishAnt: 14-Oct-2005 | Brett, I also grokked Gregg's "turtle" hunting metaphor. Already I have filled more than a page of inspirations from it. Here is a sampling of my found design patterns, mostly in REBOL which are powerful "turtles" which are concrete examples of what Gregg said: 1. View console where a user can type VID/View lines, and hit return to see what they do. 2. Using print statements to the console from a View script to understand it (so easy to do protytping) 3. Parts of layout.r IDE with Nubs, and you generate scripts (which are human readible) from the GUI. 4. The source and help systems built-in to REBOL 5. Arexx for Inter-App-Messaging (I listened intently to Gab's Reb/Services talk saying "Arexx of the X-Internet") 6. awk file parsing. (I know Gregg wrote rawk.r a while back) ... "Turtle hunting" challenges us to develop more of these. | |

Pekr: 13-Sep-2007 | I did not want to offend you. I never worked with Flash, so my question was just curiousity, if creating Flash stuff that way could be usefull outside REBOL community, or would 99% ppl prefer visual IDE for such purpose? | |
Oldes: 13-Sep-2007 | I would like to create something like a rebol/flash vid in a future. and what I can say is, that I don't like the visual IDE too much for coding. All the actions on different frames and in different sprites. | |
Cyphre: 7-Jan-2010 | Janko, the Rebol/Flash dialect is basically compiler of flash(swf) files which uses own specific language - dialect for that. I think programmers who are working(painfully) with Flash IDE every day would love it. I don't understand why the dialect is not well known in the Flash comunity. Maybe because you need to learn from the examples on the website and also get Rebol in your mind a bit ;) | |

Gabriele: 5-Jun-2007 | petr, corporate environment means that we should provide 6 dvds of rebol ide | |
Ammon: 17-Jan-2008 | Yes, I have LOTS of ideas for an IDE! A few months after joining the REBOL community (very soon after IOS was released) I actually started a funded IDE project for REBOL. I spent quite a bit of time discussing these ideas with Carl who agreed to release it as THE REBOL IDE but unfortunately the funding died. I've tried numerous times to renew the project all to no avail. | |
shadwolf: 24-Jul-2008 | but the IDE is an IDE in rebol to do rebol software.... But why an IDE in rebol ??? Well for a lot of reason 1) promotion purpose .... Rebol don't need anything else than rebol to do his dev tools ... and if we can do dev tools as sharp as you can see it with rebol that means rebol can do alot for your company too. 2) cause rebol is what we are doing here ^^... Other language are other languages More rebol to save the people ^^.... 3) because who knows better what we need and what we want than us maybe the strongest and the first to believe in rebol 4) because IDE in rebol can make us share the code and work together on a base project where anyone will apport his ideas tries and that's what is a community all about doing there own project on their sides sharing informations and experiencies and gathering around hudge project or mendatory projects ( like rebgui ^^) | |
Pekr: 22-Oct-2008 | Today I was supposed to try to edit one corporate .swf file. Oldes suggested me some decompiler. There are items like - shape, image, font, text, button, frame, action, misc tags ( http://www.xidys.com/pekr/flash-structure.jpg ). It seems like flash (dunno if decompiled view is identikal to their proper IDE) is using kind of page-layout engine. Our corporate flash presentation is like browsing dynamic web. So far, with VID3, I can't see enough of "rebol browser" in there, but more an app dev. platform. What is our equivalent of "page" - is it a 'panel? | |
Steeve: 18-Nov-2008 | It has been said by many rebolers all over the past, the Killer app should be an IDE (including code editor, screen designer and other wizards). It the only manner to encourage new groups of developper in starting huge projets with Rebol. | |
shadwolf: 9-Apr-2009 | Pekr r3 doesn't exist ... I know i'm a stubborn moron ^^ that's my way to be 1st it's on R2 complete and full wrokking then i will adapt it to rebGUI then i will do REBOL IDE then in that time R3 will be official released and i will do the port | |
shadwolf: 2-Jun-2009 | next ask is do you think somthing like colaborative "at the same time" could be possible to do with R3 for example hum lets be crazy in futur viva-rebol IDE offers a way to make several ppl working on the same project at the same time use the viva-rebol IDE and sharing in real time information | |
shadwolf: 2-Jun-2009 | for example you and me works on the same file at the same time using viva-rebol ide and you fill a part of the file i fill another part of the file and we both see in real time what the other is doing. (for example you do the parse parse rules and i write the GUI of an applicaton things like that) | |
RobertS: 13-Aug-2009 | A server-side scripting language which cannot handle literal strings - and especially one that claims to be Unicode - has to be excluded from consideration for templating web content which is expressed in any other langauge which uses curly braces. I told BrianH that the red flag here should be Tcl as Rebol shares this with Tcl. Literal string are literal strings. Period. No if's and's or "that might be my curly brace in there" ... Unless you dream of a Rebol-only world - and that fantasy should have passed some years back. This falls under the heading of folly - a topic too often neglected. Folly in a meritocracy usually requires some individual to speak up. But the folly of meritocracies is that to be heard taht individual would already have to be playing within those constraints. We see this in schools which graduate top people distinguished for inidividual effort who then do not fit well into teams. They did group work in college by being the one who saved the group from failure by ... their individual effort. For me this will be what makes or breaks my involvement with REBOL. I could not wait for REBOL4 and hope for change then by getting into the merit circle. My outside voice would have to be heard before it is too late. Tcl as the do-all is folly. As nuch as I admire OOTcl, the XOTcl IDE and Expect. I cannot use Tcl with "balanced brace" foolishness. Of course if we all adopt XML and abandon scripting in non-XML languages ... So We have comment { } and that was a mistake: it should have been symmetrical as in c{ comment here as literal with } or whatever }c And that is water under the bridge. We cannot be UNICODE and claim that we must escape a certain pair of characters if ithey are in a literal string. That is silly. Ludicrous. Folly. A literal string is a data value where you do not get to peek. Imagine a proxy object that said: "I will be your proxy only if you promise that when the real object appears it does not contain [ folly happens here ] " Many forms of "catch-22" in the world of beaurocratic regulation have a similar pattern. I am no expert on unintended consequences, but requiring that some pair of characters be escaped in otherwise literal content has consequences for TEMPLATE value TEMPLATE There should be a lesson there: some markup must be arbitrary and the choice will matter. { and } are the wrong choice. At least the terminal markup must be "sacrificed (it will always have to be escaped so pick carefully. [{ is a bad combo for JSON so #[{ looks worrisome to me. I propose lit |ls# and_content_then #ls| Someone shoots that down and we inch towards a suitable result. Not perfect. But usable. { and } are not useable in the real world on the server-side if rebol is to play a role with other languages. Play nice. Please. | |

shadwolf: 26-May-2010 | Here I come with a nuclear bomb Ask .... This document requieres Viewer Advise if upon reading those line your retina blow up I could not held responsible for that. I was htinking of the possible logical reasons why rebol is not used widly in today's computing area. First i can say compared to other scripting language it's source code is not freely accessible. Second I can say most of the script laguages use now in days is in a role where the script source code isn't available to read to the client. And so most of those script use are around Webserver, server side so the scripts are hiden to the view of the consumer (the cleint). And most of the time when a company needs to broadcast a software to their customer (a game, a client software, etc...) then they need to hide their source code. So most of the time they use compiled or speudo compiled programing language. On an ideologic side what rebol offers is "take my blackbox but you have to broacast your software source code viewable for all" Personnally i like that part .... that's what allowed me to build most of my softwares and contribute to most of some of other ones project. But I perfectly understand that for the industry they need to hide their "know how". So they use java so they use what ever compiled language to hide their "know how" Next is the fact that most of the time companies choose a langage more for the extension related to their project than for any other consideration. Compiled language are faster the script languages most of the time. So my ask is could rebol be like java compiled like language? I'm not talking about rebol/SDK to me fusing the VM binary with the script and somehow hiding the script is not the right solution that's just a cheap way to achieve that goal and rebol deserves better than cheap ways. My point is to have like java does the need to go to the rebol.com and install the REBOL runtime environement -> That strategy 1 rule 1 modo 1 in spreading your technology Why sun Java and Microsoft .NET does it and rebol not ? And there we fall to what Carl noticed and shared with us some years ago while initiating the R3 projet wich was "Administrators on IT companies doesn"t knows about REBOL so when they see it they kill it from running tasks" Maybe the whole R.E (runtime Environement) thing was made to make most of the people look at the juava or .net dedicated websites and so be informed of what is jvm or what is netvm. At taht time when CArl tried to talk about us with that the solution Carl proposed was -> "Lets change rebol names" and my reply was cold "If people after 6 years don't know rebol they won't know better anyother name the problem so i not the name is the way we spread the information". So in a way a runtime environement is the best way to populate your idea without investing to much. Next thinking is about the compiled / speudo compiled is faster than any possible scripting language. FASTER ???? IN WHAT ? those are the questions ... Most of people whould reply faster in execution ... Ok bu if i remamber well what i learn at school (yes i went to school stop laughing ...) before running a binary program you need to build the script ... and that's where most of the work time is bruned up and where the need of a IDE (intergrated Developement Environement) is needed and most of the time those IDE ends up in being a Click and feel the form ... wich is adding a complexity layer instead of simplifying the scriptiing. Intents like small talk for example that push this aspect to it's core limits were hum not widely accepted as a suitable way to build software. Mainly because they make nearly impossible to extend easyly their selfves in comparasion of other compiled languages. So we are then saying rebol is the fastest way to build applications in the world. It's a ight weight very well though scripting langages with alot of possibilities. Most of the time in one line of rebol you do as much as tens of lines in any other languga (or even more) and that's because in my opinion rebol doesn't need a heavy script grammar to exist. But you can stil make an IDE to help organise your work and speed it up and make it easyly more cooperative. But this is not the part we are discussing. So in fact what really matters in comuting area is less the time you spend building you application than the need to hide your 'how I did it' and to then have the closest possible level to your hardware for your software. And for that my friends rebol need to be speudo compiled able. And maybe the step further java in our industry is to have a keep it simple language hiding your industrial secrets but allowing you if you want to share your work in full view full access like it's actually the case. Some will say to me yes but with R3 we have new extendsions so the industrial secret can be hidden in that layer. that's right but then you don't do rebol anymore you do C and what id the purpose of embeding rebol into a complexifed C layer ... C layer is to extend our language capabilities the fastest way but not to make the need of our language to desapear ... Because in the end what we want to promote is REBOL not C language.... It's a long post I'm sorry for that but I'm thinking about it since a long long time and tonight i feeled like sharing those thoughts | |
RobertS: 21-Dec-2010 | I posted a note on Geany as a possible linux rebol tool in IDE as Carl's Rebol Blog is no place for running notes - but altme cannot tag a topic ? And trying to select a group here on linux as ALTme 1.2.25 is loading is just a crap shoot - highlight and click and close yore eyes or is it the reverse? | |

BrianH: 10-Mar-2011 | The original Java case benefits more from the concept than REBOL would because there are many addon standards like JavaDoc that need managing, but at least have been agreed upon by their community. We don't have that kind of agreement in the REBOL community. Also, the structure of the Java language is very limited, so it's a bit easier to parse it and have its structure just be in the background even though the language wasn't designed for that like Smalltalk was for its browser. For Red, since it's so early, things like integrated documentation can be developed along with the language, so something like this would make more sense. However, if Red is going to have even a large fraction of the power of REBOL then it won't be as structured as Java, making it a little more difficult to retrofit a Code Bubbles interface onto existing code. This is why you would need an IDE to understand code written in this kind of IDE: A Code Bubbles style interface doesn't generate code with story structure the way scripts are structured, so you can't just read the code without the context of the IDE. | |
shadwolf: 6-Apr-2011 | so red is compiled but then it's systeme dependant and we can't test small chunks of code like in R2 consol in my opinion one of the strong point of rebol was this ability to open it's consol test an epurated bunch of code and then once working enhance it on our script file. I would like red somehow to get that ability maybe it will be possible in the IDE or as a side stuff. For me the 2 best points of rebol were reflexivity code <--> data code = data data = code and parse. Even if I didn't fully understand parse I made a great use in my productions in rebol script VID oriented of the reflexivity code <---> data. All the other arguments of rebol are not really interresting since they are double sided and so not objective and so just a matter of mood and point of view. | |

GiuseppeC: 9-Dec-2011 | Personally I have a great private project in mind and a skilled developer for it. The project is blocked because he want to make money now and someone who finances the project. I told him that First of all we must show a concept application. This will sell the application itself and we start fundraising. Until something usable won't be ready I will not be able to sell the idea. He refuses this view and we are blocked. As you are writing a programming language you are in a worst scenarion than us. You need to have a commercial class programming language ready for the mass to sell it and this is not the case. Commercial Class mean: IDE, Solution for interfacing SQL Databases, Solutions for communicating, Solutions for interfacing to other projects. This is too much for one man to accomplish. You need to live, you need money and World is your Hobby project (Isn't it ?) Open sourcing and delegating is the solution for creating a mature project: you seth the path, the specifications, the rules, the others will help. I won't give a Penny and Time to REBOL Tech. because its source is closed and this model is wasting my precious life waiting for Carl to resurrect. Open Sourcing solves this problem. Don't you think that if REBOL was open sourced many developers would have inproved it in Carls absence ? Do you think that someone, like an university will donate money to a private held project ? I don't think so. When we (you) will have a mature project and you will be able to show to the world the advantages of your solutions money will come. Think of SQL lite. There is a consortium behind it. Other open source solutions have the same consortiums behind them. There are many ways to raise money: You can produce vertical solutions for your baby.You can give consulency to companies and other institutions, you can create products with World. These are few that comes into my mind. |
