Hello, I followed this discussion because I like the subject. Generating code. I have my own ideas about the subject and would appreciate your opinion. I read about a XML parser written in JavaScript. Then I thought about the combination Widgets and XML. We could define and document the widget in XML, create a editor to modify the widgets properties, show the result in a seperate frame and use the parser (8kb) to create a kind of javascript DOM at runtime, also storing references to widgets instances within that DOM. A little example : <html> <head> <title>fam.meenhorst.nl</title> <script language="JavaScript" src="./shared/js/dynapi.js"></script> <script language="Javascript"> DynAPI.setLibraryPath('./shared/js/lib/'); DynAPI.include('dynapi.api.*'); DynAPI.include('dynapi.util.thread'); DynAPI.include('dynapi.util.pathanim'); DynAPI.include('dynapi.util.cookies'); DynAPI.include('dynapi.gui.loadpanel'); DynAPI.include('dynapi.gui.viewport'); DynAPI.include('dynapi.gui.label'); DynAPI.include('dynapi.gui.dynimage'); DynAPI.include('dynxml.xml.*'); DynAPI.include('widget.gui.*'); </script> <script language="JavaScript" src="./shared/js/dom.js"></script> <script language="Javascript"> DynAPI.onLoad = function() { DynAPI.cookies.readCookie('theme'); selectedTheme = DynAPI.cookies.readCookie('theme'); if (!selectedTheme) selectedTheme='default'; domDesktop=dom.getAttrib(dom.getRef('/DynDOM/desktop')); domDesktopItems=dom.getAttrib(dom.getRef('/DynDOM/desktop/items')); domTheme=dom.getRef('/DynDOM/themes/' + selectedTheme); domStart=dom.getRef('/DynDOM/startmenu'); domFav=dom.getRef('/DynDOM/favorites'); // precatch theme images for (elem in domTheme.contents) { for (attr in domTheme.contents[elem].attributes) { var val = domTheme.contents[elem].attributes[attr]; if ( val.indexOf('.gif')!=0 || val.indexOf('.jpg')!=0) DynImage.getImage(val); } generate widget instances using the getAttrib and getRef functions I attached the parser and the discribed two functions. -----Original Message----- From: dyn...@li...

Subject: RE: [Dynapi-Dev] Oversight (Code generation) Yep, that's basically all.. the only thing do is create a recursive function of some sort, that walks thru all layers and child layers, and also generate the correct addChild() calls, and all EventListeners (can be done using the eventlisteners array). The only problem still remaining is the fetching of real javascript variable names... not sure if these are part of the DOM somewhere.. For a wysiwyg editor it wouldn't be a problem, you could generate your own variable names.. but for existing code you would have to use the real variable names to not screw up existing code. I also want these modules not extending the DynLayer or other DynAPI objects, but rather have there own functions to handle these things.. cya, Pascal Bestebroer (pb...@oi...)

Onderwerp: Re: [Dynapi-Dev] Oversight (Code generation) I was mucking around with this last night. the attached file is one method of doing it. Just include the attached file and call layerName.generateCode() this should return a copy of the initialisation command for the layer. Pascal wrote: Some secondary values are callable, but certain arrays will give problems (I'm trying to fix that). I'm not sure if I can retrieve variable names (anyone with an idea on that one?) But I am planning on creating an extra module like Oversight, which reads the DynAPI tree of objects (dynapi.document and all child layers) and regenarets correct code for it.. This would be the first step for wysiwyg editing.. simple attach dragevent listeners to every layer on screen so that they can be placed, call the code-generator and you have your wysiwyg editor Also another idea I'm having is including a better object watcher to Oversight.. like the one found in Delph, Visual basic ,etc.. a window showing all properties and values, make them editable and you have easy access to every object, making the Dump Object obsolete. cya, Pascal Bestebroer (pb...@oi...)
