Fix to add parentheses for TSTypeQuery in some case (#13546)

I added an if statement with the parent type the example sentence had.

a as (typeof node.children)[number]

a as (typeof node.children)[]

a as ((typeof node.children)[number])[]

+        parent.type === "TSArrayType"
+      ) {
+        return true;
+      }


We need check the property name here, in this case name === "objectType".

Prettier pr-14042
Playground link

--parser typescript

Input:

a as (typeof node.children)[number] a as (number)[typeof node.children]

Output:

a as (typeof node.children)[number]; a as number[(typeof node.children)];

a as (typeof node.children)[]

this property name was elementType
May I add a case like the code below?

return ( name === "objectType" || name === "elementType" && (parent.type === "TSIndexedAccessType" || parent.type === "TSArrayType") )

No, should be

return ( (name === "objectType" && parent.type === "TSIndexedAccessType") || (name === "elementType" && parent.type === "TSArrayType") )

Fixed in this commit.　7035317

+      ) {
+        return true;
+      }

I don't think TSTypeQuery(TypeScript node type) can be a child of NullableTypeAnnotation(flow node type). This should not fallthrough.

LGTM except for the review comments that remain now.

Thanks for working on this.

@onishi-kohei

There should be other cases need add parens, for example:

a as (typeof node.children)!

if you are interested thoses types in this branch may give you the idea to improve.

And don't send PRs from your main branch next time.

Specifically, parentheses around typeof statements. See https://github.com/prettier/prettier/blob/main/CHANGELOG.md#add-parentheses-for-tstypequery-to-improve-readability-14042-by-onishi-kohei and prettier/prettier#14042.

@onishi-kohei Does this interact cleanly with keyof typeof? I'm seeing new errors in 2.8.3:

{
  // ...
  accept: typeof MIME_TYPES[keyof typeof MIME_TYPES][];
}

14:11 Error: Replace `typeof·MIME_TYPES` with `(typeof·MIME_TYPES)` prettier/prettier

The type is ugly but is tied to a third-party library. Parentheses that are added by hand are stripped by prettier automatically.

onishi-kohei · 2023-01-18T13:55:12Z

@SamuelMS
I have verified that the following code did not generate an error.

// Input
export type A = {
  a?: {
    [
      x: string
    ]: typeof SomeLongLongLongTypeName[keyof typeof SomeLongLongLongTypeName];
  } | null;
};

@SamuelMS Make sure you don't have a caret (^) in front of Prettier's version in your package.json. See https://prettier.io/docs/en/install.html#summary

zomars · 2023-01-27T02:18:02Z

Can we disable this option?

SamuelMS · 2023-02-03T06:17:10Z

@onishi-kohei You're right, this was an environment issue – IDEA silently persisted a cached version of an older version of prettier around.
