Deprecated selector in `language-javascript-semantic/styles/semantic-colors.atom-text-editor.less`

[mwelchunium]

In language-javascript-semantic/styles/semantic-colors.atom-text-editor.less:

Starting from Atom v1.13.0, the contents of atom-text-editor elements are no longer encapsulated within a shadow DOM boundary. This means you should stop using :host and ::shadow pseudo-selectors, and prepend all your syntax selectors with syntax--. To prevent breakage with existing style sheets, Atom will automatically upgrade the following selectors:

• .source.js-semantic => .syntax--source.js-semantic

• .source.js-semantic.identifier.color-index-1 => .syntax--source.js-semantic.syntax--identifier.color-index-1

• .source.js-semantic.identifier.color-index-2 => .syntax--source.js-semantic.syntax--identifier.color-index-2

• .source.js-semantic.identifier.color-index-3 => .syntax--source.js-semantic.syntax--identifier.color-index-3

• .source.js-semantic.identifier.color-index-4 => .syntax--source.js-semantic.syntax--identifier.color-index-4

• .source.js-semantic.identifier.color-index-5 => .syntax--source.js-semantic.syntax--identifier.color-index-5

• .source.js-semantic.identifier.color-index-6 => .syntax--source.js-semantic.syntax--identifier.color-index-6

• .source.js-semantic.identifier.color-index-7 => .syntax--source.js-semantic.syntax--identifier.color-index-7

• .source.js-semantic.identifier.color-index-8 => .syntax--source.js-semantic.syntax--identifier.color-index-8

• .source.js-semantic.comment => .syntax--source.js-semantic.syntax--comment

• .source.js-semantic.keyword => .syntax--source.js-semantic.syntax--keyword

• .source.js-semantic.number => .syntax--source.js-semantic.syntax--number

• .source.js-semantic.string, .source.js-semantic.regex => .syntax--source.js-semantic.syntax--string, .syntax--source.js-semantic.syntax--regex

Automatic translation of selectors will be removed in a few release cycles to minimize startup time. Please, make sure to upgrade the above selectors as soon as possible.

If highlighting stops working, replace the contents of this file: <path-to-atom-install>\.atom\packages\language-javascript-semantic\styles\semantic-colors.atom-text-editor.less

with:

@import "syntax-variables";

@bright-text-color:
  contrast(@syntax-background-color,
      lighten(@syntax-text-color, 20%),
      darken(@syntax-text-color, 20%));

.text-color(@contrast) {
  color: mix(@bright-text-color, @syntax-background-color, @contrast);
}

.syntax--source.syntax--js-semantic {
  // Reset font attributes to prevent interference from main syntax theme
  .text-color(80%);
  background-color: transparent;
  font-style: normal;
  font-weight: normal;
  text-decoration: none;

  &.syntax--identifier {
    .color-indices(8);

    .color-indices(@n, @i: 1) when (@i =< @n) {
      @hue: @i * (360 / @n);
      &.syntax--color-index-@{i} {
        // Choose a color of the given hue with good contrast
        color: contrast(@syntax-background-color,
            hsl(@hue, 100%, 25%),
            hsl(@hue, 65%, 75%));
      }
      .color-indices(@n, @i + 1);
    }
  }

  &.syntax--comment {
    .text-color(40%);
  }

  &.syntax--keyword {
    font-weight: bold;
  }

  &.syntax--number {
    .text-color(100%);
  }

  &.syntax--string,
  &.syntax--regex {
    // TODO: Currently, these are simply the string colors from Atom's default syntax themes
    color: contrast(@syntax-background-color, #a8ff60, #dd1144);
  }
}

Worked for me.

Now Deprecation Cop shows:

Deprecated calls: No deprecated calls
Deprecated selectors: No deprecated selectors

Atom 1.14.3 for Ubuntu x64

Thanks.
