I love the new genesis widget.
It's great. It provides a far better mechanism for dynamic widgets than the old way, which was to do placeholder widget like this:
\define macro(tag:div) <$tag$>...
Placeholder widgets were bad for plugin developers like me. Take Uglify. It can't parse <$tag$>, so it actually saw it as plaintext containing a placeholder. And all it could do was stay away from it, because touching it was dangerous. As a result, Uglify becomes much less effective around them. But it can handle
<$genesis>
just fine. It's safer. It compresses better.Even Relink prefers $genesis. If it encountered
<$tag$ attribute=...>
, it couldn't relink any of its attributes at all, because it couldn't parse it as a widget. With $genesis, it can. (It may still fail to identify some string-value attributes that require relinking in some cases, but it's still far better off with a $genesis widget).In fact, my only complaint about the genesis widget is this:
Why aren't we fully embracing it?
This PR addresses that by migrating the few remaining places in core where dangerous placeholder widgets were still used.
