wait, let me back up for a moment wrt the original article. that screenshot in the article is not emacs. i can't give you a screenshot of emacs, because emacs doesn't even depend on a windowing system for near-maximum awesomeness. it is my go-to text editor, and i very likely will (progn several of these snippets into my .el files.
that said, we do have have windowing systems now, with some better ones on the way, not to mention touchscreens. i haven't tried out lighttable yet, but i intend to, and i greatly hope that either (1) lighttable follows in emacs footsteps of being fully scriptable (as opposed to the adopting a plugin model that's so typical of java ides) or (2) emacs devours all of that beyond-code-folding -- how best to say it? -- code-exploding (?) awesomeness that lighttable attempts to bring and that, to me, appears to map perfectly onto this new world we find ourselves in where computers are not giant boxes attached to printers anymore but are, instead, whole buildings attached to touchscreens.
doesn't matter if your program's a crocodile or wildabeast: adapt or die.
It's probably worth looking into the scope and design of LT plugins, they do (ostensibly) strive for full scriptability. Seeing some of the stuff people are doing integrating dev tools, tutorials (possibly one of the killer features in the future), etc. gives me some hope as an ardent emacs user that they may be onto something with LT.
More than windowing systems it's a different abstraction layer using what appears to me as being dom trees with very capable yet uncoupled presentation capabilities (css) instead of emacs buffer + text-properties, font-lock etc. Hoping it will unleash ideas, just like lisp did in its days, by providing a better language for logic/code interactions.
