Fix leading comments in mapped types with `readonly` #13427

thorn0 · 2022-09-04T12:18:34Z

Description

@sosukesuzuki I believe this is a more optimal fix than #11190. There is no need to support comments between the modifier and identifier. I used the tests from your PR.

I forgot about that PR I made myself. Your solution is excellent 👍

I noticed that this PR got merged into the next branch which I assume is 3.0?
If it is 3.0 - is there any way we could cherry-pick this across to the v2 main branch?

It seems a shame to wait until the v3 release to have this bug fixed.

Ah, I was reading this part the other day, didn't know it's not shipped yet.

I have to say what a strange AST shape, why readonly not on TSTypeParameter?

bradzacher · 2023-02-07T05:35:53Z

why readonly not on TSTypeParameter?

The TSTypeParameter specifically represents the bit within the []:

{ readonly [ Key in Type ]: Value }
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ TSMappedType
             ^^^^^^^^^^^ .typeParameter -> TSTypeParameter
                            ^^^^^^ .typeAnnotation -> TypeNode

It's not the parameter that the readonly applies to - it's the entire "property". And given that a mapped type may only have one "property" declared in it - really that means the readonly applies to the mapped type itself.

It's worth noting that it's also a REALLY weird AST here - TSTypeParameter is the wrong node for us to emit - it's an abuse of the AST lol. In all other contexts having a .constraint on a type parameter means T extends Constraint, but in a mapped type instead it means T in Constraint.

Should probably change it (filed typescript-eslint/typescript-eslint#6433)

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) ?

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}} {{! 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))  ```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 {{! Input }} {{#when isAtWork as |work|}} Ship that {{work}}! {{else when isReading as |book|}} You can finish {{book}} eventually... {{else}} Go to bed! {{/when}} {{!

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) ?
