REBOL [
    	File: %rebol-dom.r
    	Date: 02-11-2020
    	Title: "Dialect Object Model"
        Emai: inetw3.dm@gmail.com
    	Purpose: {
             Use a recodable rebol function to create easy to follow blocks/series as 
             a Dialect Object Model  that allow different program languages to work together
             and viewed as HTML and VID. A parse alternative}
    	]

library: [
        level: 'intermediate
        platform: 'all
        type: Dialect
        domain: [html vid css json js array]
        tested-under: 'windows
        support: none
        license: none
        see-also: %HTML-view.r
    ]

my-dialect: [body: [{background-color="blue" text "white"} ]
p: [
	{ "color":"#0000ff", "bgcolor":"yellow", "width" : "399", "height" : "100", "font-style": "big", }
	
 This is an example of an Dialect Oject Model
b: [
	{color = "Chocolate" bgcolor = "yellow"} 
	
 that can be written to look like json' html' javascript arrays' css'  
i: [
	{color = "green"} 
	
 VID' or plain old rebol ] 
  ] 
 if you like.
  ]

	{width="399" bgcolor="orange"}  
b: [
	{color: "purple" bgcolor: "orange"} 
	
 Maybe it would be easier to write  
i: [
	{color: "green"}
	
 MakeDoc.r code but the purpose of this rebol DOM is'	]  
   ]
 
p: [
	{width "399" height= 200 
	style={	color: red;	bgcolor: brown;	border: 2x2;} 
	} 
b: [	 
	{color="red"}
 to read or load as many well known dialects of coding styles as possible
 and write all of it as a single or seperate legible rebol series that's
 quickly manipulated' transcoded as html' and viewed as a VID. ]

**************************************************************************************************
An example of how to use the DOM functions follows. The syntax hopefully should be easy to follow being that it
resembles how you would use javascript with the HTML,XML DOM. 

It's just a little bit different, why not just make it the same?

Were not scripting against a DOM, (a Documents  Object Modle) but a DOM, (a Dialect Object Modle) because 
you may not actually know the syntax of the loaded document or data before it's transcode to a DOM from a DSL.

Plus Rebol wont let you too far off the hook in writing code any way you like. Some *op Words and  code/data 
has set types that follow a strict syntax. I think the best way around this is to load as type? string!, reformat 
and parse as type? block!. Maybe.....

These DOM functions should work very close to the HTML DOM functions:

getElementsByTagName .getAttribute .setAttribute 

....... <start:rant="on"  placed="strategically" skip="yes:no;">you don't have to readthis</rant>........................

HTML,XML DOM is built as a tree structure from a document. In order to get or set something you must search the
entire tree with each call to a tag. Before returning a single tag it must first build a nodelist of all alike tags before
a method (function call) can be used. 

You actually need a browser, editor or IDE, and code experience with , javascript, html, css, HTML DOM, XML DOM,
HTML5, and to move or share across networks, XSL, XSLT, Xpath, XQuery, Ajax, a server, and server-side/backend with
access to client-side frontends, security, and administration. WWWOOOOOWWW!.
 
Rebol parse along with block searching is simpler, faster, easier to code, send, or recieve and uses less memory.
The Rebol choir membors know how to do all that need-to-know in one language, Rebol!, WWWOOOOWWW!....

The Rebol upjump (advantage) is a serious downfall. To spend the time using others stuff (bloatware) is a big time 
waister wich leaves Rebol all but alone, by itself and unused cause that bloatware in its domain can do it better 
when it's supported by more of the standard bloatware stuff. But have you seen how many disparate languages 
you need to use in a Web full stack process. 

To get people to use Rebol it has to have modules, FFI, execute C code, plug-ins,  GPU'ed, data-based,  IOS-Android 
and media/browser  access, embedable, AI, CLOUD-able, all wrapped up with a pretty open source bow. Please. 

Thats why i believe RED is the right direction for Rebol. But the wrong direction. Because people only want stuff. Either 
that suff has to do more stuff or be a part of the best known stuff to make them feel better or a part of the best stuff
going on at that moment.

So i give in. I want Rebol to catch on, not catch up. The Rebol-DOM is a way to load every body's stuff in, parse that stuff
up, change stuff, and send that stuff back out and let that other bloatware stuff deal with it.

Rebol don't need no stuff. It needs to progressively replace it by hiding the Rebol language and acting like a cloud
Service Oriented Architecture (SOA) open source messenger through the internet. Nothing needs to change. This is what
Rebol is and does already. Rebol just needs this kind of App to materialize and offer itself up on a subscription base.
