Compared to Stylelint, Prettier is very simple tool and I am quite supprised Stylelint is deprecating the whitespace rules in favor of Prettier. For LESS it seems ok, for JS, we should never enable Prettier as formatting is part of a code and improves readability. As Prettier is an opinionated formatter instead of an linter, we need to satisfy it everywhere without exceptions. When I was crafting this PR, I found several Prettier issues and proposed changes to Prettier: Fix semicolon duplicated at the end of LESS file prettier/prettier#14007 Fix no space after unary minus when followed by opening parenthesis in LESS prettier/prettier#14008 Do not change case of property name if inside a variable declaration in LESS prettier/prettier#14034 In this PR, these changes are contained and Prettier is patched before it is run. Once the changes are merged in prettier and stable release is made, they can be removed. This PR fixes minor whitespaces unfixed/undetected in GH-2610. And also asserts: PHP port of the LESS fails to compile colors.less #1832 feat(lint): add stylelint overrides and variation files #2593 (comment) Prettier has no built in support to dump the diff - prettier/prettier#6885 - so we dump it in the CI using git.

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. <!-- prettier-ignore --> ```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)) <!-- prettier-ignore --> ```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)) <!-- prettier-ignore --> ```ts // Input type Foo<T> = T extends ((a) => a is infer R extends string) ?

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. <!-- prettier-ignore --> ```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)) <!-- prettier-ignore --> ```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)) <!-- prettier-ignore --> ```ts // Input type Foo<T> = T extends ((a) => a is infer R extends string) ?

A bad version was accidentally published and [it can't be unpublished](npm/cli#1686), apologies for the churn. ## [v2.8.7](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#287) [diff](prettier/prettier@2.8.6...2.8.7) ##### Allow multiple decorators on same getter/setter ([#14584](prettier/prettier#14584) by [@fisker](https://github.com/fisker)) <!-- prettier-ignore --> ```ts // Input class A { @decorator() get foo () {} @decorator() set foo (value) {} } // Prettier 2.8.6 SyntaxError: Decorators cannot be applied to multiple get/set accessors of the same name.

(2:3) 1 | class A { > 2 | @decorator() | ^^^^^^^^^^^^ 3 | #privateMethod () {} 4 | } // Prettier 2.8.6 class A { @decorator() #privateMethod() {} } ``` ## [v2.8.5](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#285) [diff](prettier/prettier@2.8.4...2.8.5) ##### Support TypeScript 5.0 ([#14391](prettier/prettier#14391) by [@fisker](https://github.com/fisker), [#13819](prettier/prettier#13819) by [@fisker](https://github.com/fisker), [@sosukesuzuki](https://github.com/sosukesuzuki)) TypeScript 5.0 introduces two new syntactic features: - `const` modifiers for type parameters - `export type *` declarations ##### Add missing parentheses for decorator ([#14393](prettier/prettier#14393) by [@fisker](https://github.com/fisker)) <!-- prettier-ignore --> ```jsx // Input class Person { @(myDecoratorArray[0]) greet() {} } // Prettier 2.8.4 class Person { @myDecoratorArray[0] greet() {} } // Prettier 2.8.5 class Person { @(myDecoratorArray[0]) greet() {} } ``` ##### Add parentheses for `TypeofTypeAnnotation` to improve readability ([#14458](prettier/prettier#14458) by [@fisker](https://github.com/fisker)) <!-- prettier-ignore --> ```tsx // Input type A = (typeof node.children)[]; // Prettier 2.8.4 type A = typeof node.children[]; // Prettier 2.8.5 type A = (typeof node.children)[]; ``` ##### Support `max_line_length=off` when parsing `.editorconfig` ([#14516](prettier/prettier#14516) by [@josephfrazier](https://github.com/josephfrazier)) If an .editorconfig file is in your project and it sets `max_line_length=off` for the file you're formatting, it will be interpreted as a `printWidth` of `Infinity` rather than being ignored (which previously resulted in the default `printWidth` of 80 being applied, if not overridden by Prettier-specific configuration). <!-- prettier-ignore --> ```html <!-- Input --> <div className='HelloWorld' title={`You are visitor number ${ num }`} onMouseOver={onMouseOver}/> <!-- Prettier 2.8.4 --> <div className="HelloWorld" title={`You are visitor number ${num}`} onMouseOver={onMouseOver} />; <!-- Prettier 2.8.5 --> <div className="HelloWorld" title={`You are visitor number ${num}`} onMouseOver={onMouseOver} />; ``` ## [v2.8.4](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#284) [diff](prettier/prettier@2.8.3...2.8.4) ##### Fix leading comments in mapped types with `readonly` ([#13427](prettier/prettier#13427) by [@thorn0](https://github.com/thorn0), [@sosukesuzuki](https://github.com/sosukesuzuki)) <!-- prettier-ignore --> ```tsx // Input type Type = { // comment readonly [key in Foo]; }; // Prettier 2.8.3 type Type = { readonly // comment [key in Foo]; }; // Prettier 2.8.4 type Type = { // comment readonly [key in Foo]; }; ``` ##### Group params in opening block statements ([#14067](prettier/prettier#14067) by [@jamescdavis](https://github.com/jamescdavis)) This is a follow-up to [#13930](prettier/prettier#13930) to establish wrapping consistency between opening block statements and else blocks by grouping params in opening blocks. 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. <!-- prettier-ignore --> ```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}} {{! Prettier 2.8.3 }} {{#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}} There {{/block}} {{! Prettier 2.8.4 }} {{#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}} ``` ##### Ignore files in `.sl/` ([#14206](prettier/prettier#14206) by [@bolinfest](https://github.com/bolinfest)) In [Sapling SCM](https://sapling-scm.com/), `.sl/` is the folder where it stores its state, analogous to `.git/` in Git. 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)) <!-- prettier-ignore --> ```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)) <!-- prettier-ignore --> ```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) ?

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. <!-- prettier-ignore --> ```hbs {{! Input }} {{#when isAtWork as |work|}} Ship that {{work}}! {{else when isReading as |book|}} You can finish {{book}} eventually... {{else}} Go to bed! {{/when}} {{!

A bad version was accidentally published and [it can't be unpublished](npm/cli#1686), apologies for the churn. ## [v2.8.7](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#287) [diff](prettier/prettier@2.8.6...2.8.7) ##### Allow multiple decorators on same getter/setter ([#14584](prettier/prettier#14584) by [@fisker](https://github.com/fisker)) <!-- prettier-ignore --> ```ts // Input class A { @decorator() get foo () {} @decorator() set foo (value) {} } // Prettier 2.8.6 SyntaxError: Decorators cannot be applied to multiple get/set accessors of the same name.

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. <!-- prettier-ignore --> ```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)) <!-- prettier-ignore --> ```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)) <!-- prettier-ignore --> ```ts // Input type Foo<T> = T extends ((a) => a is infer R extends string) ?

A bad version was accidentally published and [it can't be unpublished](npm/cli#1686), apologies for the churn. ## [v2.8.7](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#287) [diff](prettier/prettier@2.8.6...2.8.7) ##### Allow multiple decorators on same getter/setter ([#14584](prettier/prettier#14584) by [@fisker](https://github.com/fisker)) <!-- prettier-ignore --> ```ts // Input class A { @decorator() get foo () {} @decorator() set foo (value) {} } // Prettier 2.8.6 SyntaxError: Decorators cannot be applied to multiple get/set accessors of the same name.

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. <!-- prettier-ignore --> ```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)) <!-- prettier-ignore --> ```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)) <!-- prettier-ignore --> ```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. <!-- prettier-ignore --> ```hbs {{!

A bad version was accidentally published and [it can't be unpublished](npm/cli#1686), apologies for the churn. ## [v2.8.7](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#287) [diff](prettier/prettier@2.8.6...2.8.7) ##### Allow multiple decorators on same getter/setter ([#14584](prettier/prettier#14584) by [@fisker](https://github.com/fisker)) <!-- prettier-ignore --> ```ts // Input class A { @decorator() get foo () {} @decorator() set foo (value) {} } // Prettier 2.8.6 SyntaxError: Decorators cannot be applied to multiple get/set accessors of the same name.

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. <!-- prettier-ignore --> ```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}} {{!

Prettier 2.8.4 }} {{#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}} ``` ##### Ignore files in `.sl/` ([#14206](prettier/prettier#14206) by [@bolinfest](https://github.com/bolinfest)) In [Sapling SCM](https://sapling-scm.com/), `.sl/` is the folder where it stores its state, analogous to `.git/` in Git. 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)) <!-- prettier-ignore --> ```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)) <!-- prettier-ignore --> ```ts // Input type Foo<T> = T extends ((a) => a is infer R extends string) ?

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. <!-- prettier-ignore --> ```hbs {{!
