Bug 193173 – Web Inspector: "white" and "black" aren't recognized as color keywords

• Component: Web Inspector
• Status: RESOLVED FIXED

[Nikita Vasilyev]

Color picker doesn't show up for "color: white".

That's because "white" is the value keyboard for -apple-pay-button-style:

    -apple-pay-button-style: Array (3)
    0 "black"
    1 "white"
    2 "white-outline"

Value keywords have precedence over color keywords in External/CodeMirror/css.js:

    function wordAsValue(stream) {
      var word = stream.current().toLowerCase();
      if (valueKeywords.hasOwnProperty(word))
        override = "atom";
      else if (colorKeywords.hasOwnProperty(word))
        override = "keyword";
      else
        override = "variable";
    }

NIT: the `concat` approach is faster <https://jsperf.com/array-concat-vs-push-2/17>.

NIT: you can use the `this._properety.variable` getter and inline it in the `if`.

What would happen with the following if this wasn't changed?

    -apple-pay-button-style: white;
    color: white;
    --foo: white;

Good to know!

Neat!

It wouldn't show the color picker anywhere.

Does this address this FIXME? Maybe not completely?

It doesn't address this FIXME at all. The FIXME is about cases like `linear-gradient(#fff2db, var(--myVar))`.
