Support Angular inline styles as single template literal (#​15968 by @​sosukesuzuki)

Angular v17 supports single string inline styles.

// Input
@​Component({
  template: `<div>...</div>`,
  styles: `h1 { color: blue; }`,
})
export class AppComponent {}

// Prettier 3.2.4
@&#8203;Component({
  template: `<div>...</div>`,
  styles: `h1 { color: blue; }`,
})
export class AppComponent {}

// Prettier 3.2.5
@&#8203;Component({
  template: `<div>...</div>`,
  styles: `
    h1 {
      color: blue;
    }
  `,
})
export class AppComponent {}

Unexpected embedded formatting for Angular template (#​15969 by @​JounQin)

Computed template should not be considered as Angular component template

// Input
const template = "foobar";

@​Component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.4
const template = "foobar";

@&#8203;Component({
  [template]: `<h1>{{ hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.5
const template = "foobar";

@&#8203;Component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}

Use "json" parser for tsconfig.json by default (#​16012 by @​sosukesuzuki)

In v2.3.0, we introduced "jsonc" parser which adds trialing comma by default.

When adding a new parser we also define how it will be used based on the linguist-languages data.

tsconfig.json is a special file used by TypeScript, it uses .json file extension, but it actually uses the JSON with Comments syntax. However, we found that there are many third-party tools not recognize it correctly because of the confusing .json file extension.

We decide to treat it as a JSON file for now to avoid the extra configuration step.

To keep using the "jsonc" parser for your tsconfig.json files, add the following to your .pretterrc file

{
  "overrides": [
    {
      "files": ["tsconfig.json", "jsconfig.json"],
      "options": {
        "parser": "jsonc"
      }
    }
  ]
}
