One idea that we're discussing now is to kick off a project to make an LZX-based graphical editor. It's scope would be limited to the graphical layout, positioning, linkage, attributes, etc of LZX objects. It would not be code editing-focused -- there are tons of tools for that. It would be written in LZX, and would run in the browser. It would support "round-trip" editing, so that you could edit with an IDE/code editor, and then the visual editor, and then the code editor again, without loss. The back-end, which would read and manipulate the LZX files, would be written in Java, and would run in the same context as OL itself.

What do you think of this approach? Right now it's just a concept.

I did thought experiments and prototyped a system like this bit back. It is doable, with a set of limitations as to what can be edited. You couldn't see the effects of editing Javascript in the IDE (you'd have to compile because eval isn't strong in there) but you could see the effects of adding and removing attributes, changing layouts, etc. To me the concept hinged on building components - classes with specifications that could be read by the IDE - that would become available to use. It wouldn't just be any set of LZX code, but an easily extendable ever growing list of "prepared" classes. This way the parameters to any class could be known and displayed properly.

I saw something similar to RealBasic's IDE coming out of this approach.

I had this running in Blooms (a laszlo templating system) and although i wasn't targetting reading from LZX - it was going to choose a Blooms language intermediate that would render to LZX - I had some interesting ideas as to how the layout of the IDE would work. For instance, since the blooms thing has "server" transforms that build XML datasources, datasources would also be included in the IDE in a "cloud" that you'd pair and move around in groups of their functionality (in python fwiw). From a visual standpoint, i thought it would be nice to describe complete applications with server side resources in a single environment.

The proof of concept system properly read in the list of components and their attributes, and allowed you to make new components on screen, to prove it was possible. It seems so.

Hope this is topical,
        James.
