Is Crockford contextual coloring used in any code editor?

Question

I watched a video from YUIConf 2012 in which Douglas Crockford talks about implementing monads in JavaScript. In this conversation, he gives an example of code that uses what he calls “Contextual Coloring,” which throws out the idea of ​​coloring by language syntax and introduces different colors for different levels of coverage. Here is a link to this part of the video.

Is this contextual coloring scheme implemented by any code editor for JavaScript or any language?

I use Sublime Text and this editor, like any other code editor I came across, allows you to apply color to the syntax. I'm not sure if the plugin can solve this problem or if the editor should be designed from scratch to allow this context coloring scheme.

Answer 1

As of February 13, 2013, Crockford added a coloring feature to the experimental context in JSLint.

Answer 2

I just watched his video for this, great stuff. If you give it a try or test the project on GitHub https://github.com/daniellmb/JavaScript-Scope-Context-Coloring .

Answer 3

Now there is a package for the sublime: https://github.com/mazurov/sublime-levels

It also has an online demo at http://mazurov.imtqy.com/eslevels-demo/

Answer 5

BlueJ has this (1) - but then it also may not be. Contextual coloring for a region in javascript will certainly be more complex than any other language, such as java, which this editor runs on.

Brackets are likely to do this in the end, as they worship Crockford (2,3)

Why don't you join them to help write, or at least tell them?

Answer 6

Not that I knew. That would be great, but it would require a JavaScript-specific lexical analyzer, and it probably wouldn't work if there were any syntax errors.
