atom beta will deprecate some things we use: Deprecated selector in `build-cargo/styles/linter.less`

[oli-obk]

We should prep a release for this and make it 0.13 only

In build-cargo/styles/linter.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:

• atom-text-editor::shadow .linter-highlight.note:not(.line-number), .linter-highlight.note:not(.line-number) => atom-text-editor.editor .linter-highlight.syntax--note:not(.line-number), .linter-highlight.note:not(.line-number)

• atom-text-editor::shadow .linter-highlight.note .linter-gutter, .linter-highlight.note .linter-gutter => atom-text-editor.editor .linter-highlight.syntax--note .linter-gutter, .linter-highlight.note .linter-gutter

• atom-text-editor::shadow .linter-highlight.note .region, .linter-highlight.note .region => atom-text-editor.editor .linter-highlight.syntax--note .region, .linter-highlight.note .region

• atom-text-editor::shadow .linter-highlight.help:not(.line-number), .linter-highlight.help:not(.line-number) => atom-text-editor.editor .linter-highlight.syntax--help:not(.line-number), .linter-highlight.help:not(.line-number)

• atom-text-editor::shadow .linter-highlight.help .linter-gutter, .linter-highlight.help .linter-gutter => atom-text-editor.editor .linter-highlight.syntax--help .linter-gutter, .linter-highlight.help .linter-gutter

• atom-text-editor::shadow .linter-highlight.help .region, .linter-highlight.help .region => atom-text-editor.editor .linter-highlight.syntax--help .region, .linter-highlight.help .region

• atom-text-editor::shadow .linter-highlight.macro:not(.line-number), .linter-highlight.macro:not(.line-number) => atom-text-editor.editor .linter-highlight.syntax--macro:not(.line-number), .linter-highlight.macro:not(.line-number)

• atom-text-editor::shadow .linter-highlight.macro .linter-gutter, .linter-highlight.macro .linter-gutter => atom-text-editor.editor .linter-highlight.syntax--macro .linter-gutter, .linter-highlight.macro .linter-gutter

• atom-text-editor::shadow .linter-highlight.macro .region, .linter-highlight.macro .region => atom-text-editor.editor .linter-highlight.syntax--macro .region, .linter-highlight.macro .region

• atom-text-editor::shadow .linter-highlight.panic:not(.line-number), .linter-highlight.panic:not(.line-number) => atom-text-editor.editor .linter-highlight.panic:not(.line-number), .linter-highlight.panic:not(.line-number)

• atom-text-editor::shadow .linter-highlight.panic .linter-gutter, .linter-highlight.panic .linter-gutter => atom-text-editor.editor .linter-highlight.panic .linter-gutter, .linter-highlight.panic .linter-gutter

• atom-text-editor::shadow .linter-highlight.panic .region, .linter-highlight.panic .region => atom-text-editor.editor .linter-highlight.panic .region, .linter-highlight.panic .region

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.
