Update:

Sorry, I got it wrong, the isArrowFunctionVariable check is not the problem.

@thorn0 This regression introduced in #11515, so I guess we should add name check instead of move .length === 0 out? 07d8883

But changed output of #11515

This reverts commit 1ebe00e.

This reverts commit 07d8883.

The name check shouldn't affect anything as far as I can see. A VariableDeclarator node has only two subnodes: init and id. It's already known that init is an arrow function. So an Identifier node can only be id.
update: I see, you've figured it out

This is not ideal but not critical either.

Multi line comment can get ugly.

This causes params to break to a new line together and not be split across lines unless the length of params exceeds the print width. This also updates the else block wrapping to behave exactly the same as opening blocks.  ```hbs {{! Input }} {{#block param param param param param param param param param param as |blockParam|}} Hello {{else block param param param param param param param param param param as |blockParam|}} There {{/block}} {{!

This causes params to break to a new line together and not be split across lines unless the length of params exceeds the print width. This also updates the else block wrapping to behave exactly the same as opening blocks.  ```hbs {{! Input }} {{#block param param param param param param param param param param as |blockParam|}} Hello {{else block param param param param param param param param param param as |blockParam|}} There {{/block}} {{!

This causes params to break to a new line together and not be split across lines unless the length of params exceeds the print width. This also updates the else block wrapping to behave exactly the same as opening blocks.  ```hbs {{!

It should be ignored in Prettier like the other SCM folders. ##### Recognize `@satisfies` in Closure-style type casts ([#14262](prettier/prettier#14262) by [@fisker](https://github.com/fisker))  ```jsx // Input const a = /** @Satisfies {Record<string, string>} */ ({hello: 1337}); const b = /** @type {Record<string, string>} */ ({hello: 1337}); // Prettier 2.8.3 const a = /** @Satisfies {Record<string, string>} */ { hello: 1337 }; const b = /** @type {Record<string, string>} */ ({ hello: 1337 }); // Prettier 2.8.4 const a = /** @Satisfies {Record<string, string>} */ ({hello: 1337}); const b = /** @type {Record<string, string>} */ ({hello: 1337}); ``` ##### Fix parens in inferred function return types with `extends` ([#14279](prettier/prettier#14279) by [@fisker](https://github.com/fisker))  ```ts // Input type Foo<T> = T extends ((a) => a is infer R extends string) ?

This updates printer-glimmer to allow block params with custom "else if"-like blocks.  ```hbs {{!

So we now support it via `babel-ts` parser.  ```tsx class Foo { accessor prop: number; } ``` ##### Fix formatting of empty type parameters ([#14073](prettier/prettier#14073) by [@fisker](https://github.com/fisker))  ```jsx // Input const foo: bar</* comment */> = () => baz; // Prettier 2.8.1 Error: Comment "comment" was not printed.

This causes params to break to a new line together and not be split across lines unless the length of params exceeds the print width. This also updates the else block wrapping to behave exactly the same as opening blocks.  ```hbs {{! Input }} {{#block param param param param param param param param param param as |blockParam|}} Hello {{else block param param param param param param param param param param as |blockParam|}} There {{/block}} {{!

This causes params to break to a new line together and not be split across lines unless the length of params exceeds the print width. This also updates the else block wrapping to behave exactly the same as opening blocks.  ```hbs {{! Input }} {{#block param param param param param param param param param param as |blockParam|}} Hello {{else block param param param param param param param param param param as |blockParam|}} There {{/block}} {{!

It should be ignored in Prettier like the other SCM folders. ##### Recognize `@satisfies` in Closure-style type casts ([#14262](prettier/prettier#14262) by [@fisker](https://github.com/fisker))  ```jsx // Input const a = /** @Satisfies {Record<string, string>} */ ({hello: 1337}); const b = /** @type {Record<string, string>} */ ({hello: 1337}); // Prettier 2.8.3 const a = /** @Satisfies {Record<string, string>} */ { hello: 1337 }; const b = /** @type {Record<string, string>} */ ({ hello: 1337 }); // Prettier 2.8.4 const a = /** @Satisfies {Record<string, string>} */ ({hello: 1337}); const b = /** @type {Record<string, string>} */ ({hello: 1337}); ``` ##### Fix parens in inferred function return types with `extends` ([#14279](prettier/prettier#14279) by [@fisker](https://github.com/fisker))  ```ts // Input type Foo<T> = T extends ((a) => a is infer R extends string) ? R : never; // Prettier 2.8.3 (First format) type Foo<T> = T extends (a) => a is infer R extends string ?

This updates printer-glimmer to allow block params with custom "else if"-like blocks.  ```hbs {{!

This causes params to break to a new line together and not be split across lines unless the length of params exceeds the print width. This also updates the else block wrapping to behave exactly the same as opening blocks.  ```hbs {{!

It should be ignored in Prettier like the other SCM folders. ##### Recognize `@satisfies` in Closure-style type casts ([#14262](prettier/prettier#14262) by [@fisker](https://github.com/fisker))  ```jsx // Input const a = /** @Satisfies {Record<string, string>} */ ({hello: 1337}); const b = /** @type {Record<string, string>} */ ({hello: 1337}); // Prettier 2.8.3 const a = /** @Satisfies {Record<string, string>} */ { hello: 1337 }; const b = /** @type {Record<string, string>} */ ({ hello: 1337 }); // Prettier 2.8.4 const a = /** @Satisfies {Record<string, string>} */ ({hello: 1337}); const b = /** @type {Record<string, string>} */ ({hello: 1337}); ``` ##### Fix parens in inferred function return types with `extends` ([#14279](prettier/prettier#14279) by [@fisker](https://github.com/fisker))  ```ts // Input type Foo<T> = T extends ((a) => a is infer R extends string) ?

This updates printer-glimmer to allow block params with custom "else if"-like blocks.  ```hbs {{!

It should be ignored in Prettier like the other SCM folders. ##### Recognize `@satisfies` in Closure-style type casts ([#14262](prettier/prettier#14262) by [@fisker](https://github.com/fisker))  ```jsx // Input const a = /** @Satisfies {Record<string, string>} */ ({hello: 1337}); const b = /** @type {Record<string, string>} */ ({hello: 1337}); // Prettier 2.8.3 const a = /** @Satisfies {Record<string, string>} */ { hello: 1337 }; const b = /** @type {Record<string, string>} */ ({ hello: 1337 }); // Prettier 2.8.4 const a = /** @Satisfies {Record<string, string>} */ ({hello: 1337}); const b = /** @type {Record<string, string>} */ ({hello: 1337}); ``` ##### Fix parens in inferred function return types with `extends` ([#14279](prettier/prettier#14279) by [@fisker](https://github.com/fisker))  ```ts // Input type Foo<T> = T extends ((a) => a is infer R extends string) ? R : never; // Prettier 2.8.3 (First format) type Foo<T> = T extends (a) => a is infer R extends string ? R : never; // Prettier 2.8.3 (Second format) SyntaxError: '?' expected. // Prettier 2.8.4 type Foo<T> = T extends ((a) => a is infer R extends string) ? R : never; ``` ## [v2.8.3](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#283) [diff](prettier/prettier@2.8.2...2.8.3) ##### Allow self-closing tags on custom elements ([#14170](prettier/prettier#14170) by [@fisker](https://github.com/fisker)) See [Angular v15.1.0 release note](https://github.com/angular/angular/releases/tag/15.1.0) for details.  ```html // Input <app-test/> // Prettier 2.8.2 SyntaxError: Only void and foreign elements can be self closed "app-test" (1:1) > 1 | <app-test/> | ^^^^^^^^^ 2 | // Prettier 2.8.3 <app-test /> ``` ## [v2.8.2](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#282) [diff](prettier/prettier@2.8.1...2.8.2) ##### Don't lowercase link references ([#13155](prettier/prettier#13155) by [@DerekNonGeneric](https://github.com/DerekNonGeneric) & [@fisker](https://github.com/fisker))  ```markdown  We now don't strictly follow the release notes format suggested by [Keep a Changelog].

Prettier 2.8.2 }} <div /> <div></div> <custom-component /> <custom-component></custom-component> <i /> <i></i> <Component /> <Component /> ``` ##### Allow custom "else if"-like blocks with block params ([#13930](prettier/prettier#13930) by [@jamescdavis](https://github.com/jamescdavis)) [#13507](prettier/prettier#13507) added support for custom block keywords used with `else`, but failed to allow block params. This updates printer-glimmer to allow block params with custom "else if"-like blocks.  ```hbs {{!

So we now support it via `babel-ts` parser.  ```tsx class Foo { accessor prop: number; } ``` ##### Fix formatting of empty type parameters ([#14073](prettier/prettier#14073) by [@fisker](https://github.com/fisker))  ```jsx // Input const foo: bar</* comment */> = () => baz; // Prettier 2.8.1 Error: Comment "comment" was not printed.
