This PR updates the plugin type declaration builder to include printers alongside parsers.

While working on a plugin, I ended up having to shim prettier/plugins/estree locally. This change exposes types for values that are already available at runtime, making them accessible without workarounds.

I’m not sure whether the added tests provide sufficient coverage. I’d appreciate any guidance on how to improve them.

Thanks for the review!

@fisker — Any chance you’ll be releasing 3.8.1 anytime soon?

fisker · 2026-01-21T17:17:43Z

The main branch is not ready for release, I can cherry-pick to v3.8.x to make a release if necessary, but I feel this can wait.

porada · 2026-01-21T17:19:52Z

Noted. If this could be released within the next few days, that’d be amazing.

Is prettier-plugin-expand-json that you are working on?

Released https://github.com/prettier/prettier/releases/tag/3.8.1

porada · 2026-01-21T17:51:17Z

Yes. This is where I came across the type issue in the first place.

Install the plugin: ```bash yarn add --dev prettier @prettier/plugin-yuku ``` 2. Add it to your `.prettierrc`: ```yaml plugins: - "@prettier/plugin-yuku" ``` Due to package size limitations, this plugin is not bundled with the main prettier package and must be installed separately.

For example `type(<number>+)` was being converted into `type(<number> +)` which is invalid CSS and does not work.  ```css /* Input */ div { border-radius: attr(br type(<length>+)); } /* Prettier 3.9.4 */ div { border-radius: attr(br type(<length> +)); } /* Prettier 3.9.5 */ div { border-radius: attr(br type(<length>+)); } ``` ##### Less: Remove spaces between merge markers and colons ([#19517](prettier/prettier#19517) by [@kovsu](https://github.com/kovsu))  ```less // Input a { box-shadow + : 0 0 1px #000; } // Prettier 3.9.4 a { box-shadow+ : 0 0 1px #000; } // Prettier 3.9.5 a { box-shadow+: 0 0 1px #000; } ``` ##### Markdown: Preserve wiki links with aliases ([#19527](prettier/prettier#19527) by [@kovsu](https://github.com/kovsu))  ```markdown  [[Foo:Bar]]  [[Foo]]  [[Foo:Bar]] ``` ##### TypeScript: Fix comments being dropped on shorthand `type` import/export specifiers ([#19565](prettier/prettier#19565) by [@kirkwaiblinger](https://github.com/kirkwaiblinger))  ```tsx // Input export { type /* comment */ T } from "foo"; import { type /* comment */ T } from "foo"; // Prettier 3.9.4 Error: Comment "comment" was not printed. Please report this error! // Prettier 3.9.5 export { type /* comment */ T } from "foo"; import { type /* comment */ T } from "foo"; ``` ##### Miscellaneous: Preserving comments' `placement` property ([#19567](prettier/prettier#19567) by [@Janther](https://github.com/Janther)) Prettier\@3.9.0 deleted an undocumented property on comments, which was already used by plugins, `comment.placement` is now available again after comment attach. ##### Flow: Stop enforcing empty module declaration to break ([#19568](prettier/prettier#19568) by [@fisker](https://github.com/fisker))  ```flow // Input declare module "foo" {} // Prettier 3.9.4 declare module "foo" { } // Prettier 3.9.5 declare module "foo" {} ``` ##### Angular: Support expression for exhaustive typechecking ([#19571](prettier/prettier#19571) by [@fisker](https://github.com/fisker))  ```html  @switch (state.mode) { @default never(state); }  @switch (state.mode) { @default never; }  @switch (state.mode) { @default never(state); } ``` ##### TypeScript: Ignore comments inside mapped type when checking type parameter comments ([#19572](prettier/prettier#19572) by [@fisker](https://github.com/fisker))  ```tsx // Input foo<{ // comment [key in keyof Foo]: number }>(); // Prettier 3.9.4 foo< { // comment [key in keyof Foo]: number; } >(); // Prettier 3.9.5 foo<{ // comment [key in keyof Foo]: number; }>(); ``` ##### Less: Fix adjacent block comments being corrupted ([#19574](prettier/prettier#19574) by [@kovsu](https://github.com/kovsu))  ```less // Input /* a *//* b */ /* a */* { color: red; } // Prettier 3.9.4 /* a */ /* b */ /* a * { color: red; } // Prettier 3.9.5 /* a */ /* b */ /* a */ * { color: red; } ``` ##### JavaScript: Handle dangling comments in `SwitchStatement` ([#19581](prettier/prettier#19581) by [@fisker](https://github.com/fisker))  ```jsx // Input switch (foo) { // comment } // Prettier 3.9.4 switch ( foo // comment ) { } // Prettier 3.9.5 switch (foo) { // comment } ``` ##### TypeScript: Remove space in comment-only object type ([#19583](prettier/prettier#19583) by [@fisker](https://github.com/fisker))  ```tsx // Input var foo = { /* comment */ }; type Foo = { /* comment */ }; // Prettier 3.9.4 var foo = {/* comment */}; type Foo = { /* comment */ }; // Prettier 3.9.5 var foo = {/* comment */}; type Foo = {/* comment */}; ``` ##### [v3.9.4](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#394) [diff](prettier/prettier@3.9.3...3.9.4) ##### Angular: Format `@content(name)` -> `@content (name)` to align with other block syntax ([#19499](prettier/prettier#19499) by [@fisker](https://github.com/fisker))  ```html  <FancyButton [label]="title"> @content (icon) { <span>Icon!</span> } @content (description) { <span>Description text</span> } <span>Other children</span> </FancyButton>  <FancyButton [label]="title"> @content(icon) { <span>Icon!</span> } @content(description) { <span>Description text</span> } <span>Other children</span> </FancyButton>  <FancyButton [label]="title"> @content (icon) { <span>Icon!</span> } @content (description) { <span>Description text</span> } <span>Other children</span> </FancyButton> ``` ##### [v3.9.3](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#393) [diff](prettier/prettier@3.9.1...3.9.3) ##### Markdown: Fix unexpected removal of characters in liquid syntax ([#19489](prettier/prettier#19489) by [@seiyab](https://github.com/seiyab))  ```md // Input  {{ page.title }} text  {{ page.title text  {{ page.title }} text ``` ##### TypeScript: Allow decorators to be used with declare on class fields ([#19492](prettier/prettier#19492) by [@evoactivity](https://github.com/evoactivity)) Extensively used within the Ember ecosystem, decorators with `declare` on class fields will ignore the babel parser error and allow Prettier to format the code without breaking it.  ```ts // Input export default class ProjectStatusComponent extends Component<ProjectStatusSig> { @service declare server: ServerService; } // Prettier 3.9.1 // SyntaxError: Decorators can't be used with a declare field.
