`v3.9.5`

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:

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

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.

/* Input */
div {
  border-radius: attr(br type(<length>+));
}

/* Prettier 3.9.4 */
div {
  border-radius: attr(br type(<length> +));
}

}

// Input

// Prettier 3.6.0 (--parser=babel-ts)
SyntaxError: Unexpected token (1:21)

Miscellaneous: Avoid closing files multiple times (#17665 by @43081j)

When reading a file to infer the interpreter from a shebang, we use the
n-readlines library to read the first line in order to get the shebang.

This library closes files when it reaches EOF, and we later try close the same
files again. We now close files only if n-readlines did not already close
them.

// Prettier 3.5.2
type T<U> = "a" | "b" extends U ? "c" : empty;

// Prettier 3.5.3
type T<U> = "a" | ("b" extends U ? "c" : empty);
type T<U> = "a" & ("b" extends U ? "c" : empty);

`v3.5.2`

Remove `module-sync` condition (#17156 by @fisker)

In Prettier 3.5.0, we added module-sync condition to package.json, so that require("prettier") can use ESM version, but turns out it doesn't work if CommonJS and ESM plugins both imports builtin plugins. To solve this problem, we decide simply remove the module-sync condition, so require("prettier") will still use the CommonJS version, we'll revisit until require(ESM) feature is more stable.

`v3.5.1`

Fix CLI crash when cache for old version exists (#17100 by @sosukesuzuki)

Prettier 3.5 uses a different cache format than previous versions, Prettier 3.5.0 crashes when reading existing cache file, Prettier 3.5.1 fixed the problem.

`v3.5.0`

`v3.4.2`

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) -->

C言
語
・
C++
・
Go
・
Rust

<!-- Prettier 3.4.1 -->
C言語・ C++ ・ Go ・ Rust

<!-- 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
  /**

  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

// Prettier 3.4.2

`v3.3.3`

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)

@Component({

})
export class AppComponent {}

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

In v3.2.0, we introduced "jsonc" parser which adds trailing 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 .prettierrc file

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