I saw you are adding callAncestor, are worrying about the performance issue?
I don't think this PR makes much differences, but I agree this can be improved without searching useless ExpressionStatement.

You may want try use getAncestors() added in next branch, you can add an option to yield key info to it.

I'm experimenting with solving #7976, and it works, but I'm not sure about the performance of this solution.
The idea of callAncestor is to get a path object for the ancestor, so that we could call needsParens for it (or any other function that needs a path). getAncestors() won't give me a path.

I don't see what you mean here BTW. I just needed to pass a path to startsWithNoLookaheadToken instead of a node.

fisker · 2022-12-29T12:09:59Z

I mean in this PR. The following case

a(
	b(
		c(
			{}.toString()
		)
	)
)

The ObjectExpression is obviously not the head of ExpressionStatement, but we can't tell until I found ExpressionStatement.

I don't think this PR makes much differences,

Previously, we can't tell that variable a is not a node need parens, until it found the most left node. So I guess there are not much difference.

thorn0 · 2022-12-29T12:13:25Z

Ah, got you now. Yes, this PR looks harmless from the performance point of view.

fisker · 2022-12-29T12:21:12Z

When I learn write babel plugin, I saw babel's NodePath is not a state machine. But I haven't read how it works. Maybe we can borrow some ideas from there.

thorn0 · 2022-12-29T12:29:21Z

They seem to create a new path object for each node. It's as an optimization that Prettier doesn't do that.

RecordExpression should be included?

No, #{}.toString() is valid.

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 {{!

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; ``` ## [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].

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.
