Treat U+30A0 & U+30FB in Katakana Block as CJK (#​16796 by @​tats-u)

Prettier doesn't treat U+30A0 & U+30FB as Japanese. U+30FB is commonly used in Japanese to represent the delimitation of first and last names of non-Japanese people or “and”. The following “C言語・C++・Go・Rust” means “C language & C++ & Go & Rust” in Japanese.

<!-- Input (--prose-wrap=never) -->

<!-- Prettier 3.4.1 -->

<!-- Prettier 3.4.2 -->
C言語・C++・Go・Rust

U+30A0 can be used as the replacement of the - in non-Japanese names (e.g. “Saint-Saëns” (Charles Camille Saint-Saëns) can be represented as “サン゠サーンス” in Japanese), but substituted by ASCII hyphen (U+002D) or U+FF1D (full width hyphen) in many cases (e.g. “サン=サーンス” or “サン＝サーンス”).

Fix comments print on class methods with decorators (#​16891 by @​fisker)

// Input
class A {
  @​decorator
  /** 
   * The method description
   *
  */
  async method(foo: Foo, bar: Bar) {
    console.log(foo);
  }
}

// Prettier 3.4.1
class A {
  @​decorator
  async /**
   * The method description
   *
   */
  method(foo: Foo, bar: Bar) {
    console.log(foo);
  }
}

// Prettier 3.4.2
class A {
  @​decorator
  /**
   * The method description
   *
   */
  async method(foo: Foo, bar: Bar) {
    console.log(foo);
  }
}

Fix non-idempotent formatting (#​16899 by @​seiyab)

This bug fix is not language-specific. You may see similar change in any languages. This fixes regression in 3.4.0 so change caused by it should yield same formatting as 3.3.3.

// Input
<div>
  foo
  <span>longlonglonglonglonglonglonglonglonglonglonglonglonglonglongl foo</span>
  , abc
</div>;

// Prettier 3.4.1 (first)
<div>
  foo
  <span>
    longlonglonglonglonglonglonglonglonglonglonglonglonglonglongl foo
  </span>, abc
</div>;

// Prettier 3.4.1 (second)
<div>
  foo
  <span>longlonglonglonglonglonglonglonglonglonglonglonglonglonglongl foo</span>
  , abc
</div>;

// Prettier 3.4.2
<div>
  foo
  <span>longlonglonglonglonglonglonglonglonglonglonglonglonglonglongl foo</span>
  , abc
</div>;

Add parentheses for nullish coalescing in ternary (#​16391 by @​cdignam-segment)

This change adds clarity to operator precedence.

// Input
foo ? bar ?? foo : baz;
foo ?? bar ? a : b;
a ? b : foo ?? bar;

// Prettier 3.3.2
foo ? bar ?? foo : baz;
foo ?? bar ? a : b;
a ? b : foo ?? bar;

// Prettier 3.3.3
foo ? (bar ?? foo) : baz;
(foo ?? bar) ? a : b;
a ? b : (foo ?? bar);

Add parentheses for decorator expressions (#​16458 by @​y-schneider)

Prevent parentheses around member expressions or tagged template literals from being removed to follow the stricter parsing rules of TypeScript 5.5.

// Input
@​(foo`tagged template`)
class X {}

// Prettier 3.3.2
@​foo`tagged template`
class X {}

// Prettier 3.3.3
@​(foo`tagged template`)
class X {}

Support @let declaration syntax (#​16474 by @​sosukesuzuki)

Adds support for Angular v18 @let declaration syntax.

Please see the following code example. The @let declaration allows you to define local variables within the template:

@​let name = 'Frodo';

<h1>Dashboard for {{name}}</h1>
Hello, {{name}}

For more details, please refer to the excellent blog post by the Angular Team: Introducing @​let in Angular.

We also appreciate the Angular Team for kindly answering our questions to implement this feature.

Unexpected embedded formatting for Angular template (#​15969 by @​JounQin)

Computed template should not be considered as Angular component template

@​Component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.4
const template = "foobar";

@&#8203;Component({
  [template]: `<h1>{{ hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.5
const template = "foobar";

@&#8203;Component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}

Use "json" parser for tsconfig.json by default (#​16012 by @​sosukesuzuki)

In v2.3.0, we introduced "jsonc" parser which adds trialing comma by default.

When adding a new parser we also define how it will be used based on the linguist-languages data.

tsconfig.json is a special file used by TypeScript, it uses .json file extension, but it actually uses the JSON with Comments syntax. However, we found that there are many third-party tools not recognize it correctly because of the confusing .json file extension.

We decide to treat it as a JSON file for now to avoid the extra configuration step.

To keep using the "jsonc" parser for your tsconfig.json files, add the following to your .pretterrc file

{
  "overrides": [
    {
      "files": ["tsconfig.json", "jsconfig.json"],
      "options": {
        "parser": "jsonc"
      }
    }
  ]
}
