Is Crockford style Context Coloring implemented in any code editor?
I use Sublime Text and this editor like every other code editor I have come across allows color to be applied to syntax. Im not sure if a plugin could solve this problem or if an editor would have to be designed from the ground up to allow this context coloring scheme.
As of Feb-13th 2013 Crockford has added an experimental context coloring feature to JSLint.
There's a package for sublime now: https://github.com/mazurov/sublime-levels
It also has an online live demo at http://mazurov.github.io/eslevels-demo/
The folks writing Brackets will probably do it eventually since they worship Crockford (2,3)
Why not join them in helping write it or at least tell them to?
