JavaScript: Added a new official plugin @prettier/plugin-yuku (#​19628, #​19629 by @​fisker)

@prettier/plugin-yuku is powered by Yuku (A high-performance JavaScript/TypeScript compiler toolchain written in Zig).

This plugin includes two new parsers: yuku (JavaScript syntax) and yuku-ts (TypeScript syntax).

To use this plugin:

1. Install the plugin:

   yarn add --dev prettier @prettier/plugin-yuku

2. Add it to your .prettierrc:

   plugins:
     - "@prettier/plugin-yuku"

Due to package size limitations, this plugin is not bundled with the main prettier package and must be installed separately.

For more information, check the package homepage.

Big thanks to @​arshad-yaseen for his excellent work.

Markdown: Cap ordered list mark at 999,999,999 (#​19351 by @​tats-u)

CommonMark parsers only support ordered list item numbers up to 999,999,999.

With this change, Prettier now caps the ordered list item number at 999,999,999 to ensure that the output is correctly parsed as an ordered list by CommonMark parsers. Numbers larger than 999,999,999 are not parsed as list item numbers and are left unchanged in the output:

<!-- Input -->

Markdown: Avoid corrupting empty link with title (#​19487 by @​andersk)

Do not remove <> from an inline link or image with an empty URL and a title, as this removal would change its interpretation.

Less: Remove extra spaces after [ in map lookups (#​19503 by @​kovsu)

CSS: Prevent addition space in type() with + (#​19516 by @​bigandy)

This fixes the addition space before + in CSS type() declaration. For example type(<number>+) was being converted into type(<number> +) which is invalid CSS and does not work.

Extensively used within the Ember ecosystem, decorators with declare on class fields will ignore the babel parser error and allow Prettier to format the code without breaking it.

export default class ProjectStatusComponent extends Component<ProjectStatusSig> {
  @service declare server: ServerService;
}
