TypeScript: Add trailing comma in tsx, only for arrow function ([#6190] by [@sosukesuzuki])
Prettier inserts a trailing comma to single type parameter for arrow functions in tsx, since v 1.18. But, this feature inserts a trailing comma to type parameter for besides arrow functions too (e.g, function , interface). This change fix it.
<!-- prettier-ignore -->// Input
interface Interface1<T> {
one: "one";
}
function function1<T>() {
return "one";
}
// Output (Prettier 1.18.0)
interface Interface1<T,> {
one: "one";
}
function function1<T,>() {
return "one";
}
// Output (Prettier 1.18.1)
interface Interface1<T> {
one: "one";
}
function function1<T>() {
return "one";
}
Config: Match dotfiles in config overrides ([#6194] by [@duailibe])
When using overrides
in the config file, Prettier was not matching dotfiles (files that start with .
). This was fixed in 1.18.1

Range: Fix ranged formatting not using the correct line width ([#6050] by [@mathieulj])
<!-- prettier-ignore -->// Input
function f() {
if (true) {
call("this line is 79 chars", "long", "it should", "stay as single line");
}
}
// Output (Prettier 1.17.0 run with --range-start 30 --range-end 110)
function f() {

}
}
// Output (Prettier 1.17.0 run without range)
function f() {
if (true) {
call("this line is 79 chars", "long", "it should", "stay as single line");
}
}
// Output (Prettier 1.17.1 with and without range)

if (true) {
call("this line is 79 chars", "long", "it should", "stay as single line");
}

JavaScript: Fix closure compiler typecasts ([#5947] by [@jridgewell])
If a closing parenthesis follows after a typecast in an inner expression, the typecast would wrap everything to the that following parenthesis.
<!-- prettier-ignore -->// Input
test(/** @type {!Array} */(arrOrString).length);
test(/** @type {!Array} */((arrOrString)).length + 1);
// Output (Prettier 1.17.0)
test(/** @type {!Array} */ (arrOrString.length));
test(/** @type {!Array} */ (arrOrString.length + 1));
// Output (Prettier 1.17.1)
test(/** @type {!Array} */ (arrOrString).length);
test(/** @type {!Array} */ (arrOrString).length + 1);
JavaScript: respect parenthesis around optional chaining before await ([#6087] by [@evilebottnawi])
<!-- prettier-ignore -->// Input

var x = (await foo.bar.blah)?.hi;
}
// Output (Prettier 1.17.0)
async function myFunction() {
var x = await foo.bar.blah?.hi;

JavaScript: Improved multiline closure compiler typecast comment detection ([#6070] by [@yangsu])
Previously, multiline closure compiler typecast comments with lines that start with * weren't flagged correctly and the subsequent parenthesis were stripped. Prettier 1.17.1 fixes this issue.
<!-- prettier-ignore -->// Input
const style =/**
* @type {{
* width: number,
* }}
*/({
width,
});
// Output (Prettier 1.17.0)
const style =/**

*/ {
width,
};
// Output (Prettier 1.17.1)

API: Fix prettier.getSupportInfo()
reporting babel parser for older versions of Prettier. ([#5826] by [@azz])
In version 1.16.0
of Prettier, the babylon
parser was renamed to babel
. Unfortunately this lead to a minor breaking change: prettier.getSupportInfo('1.15.0')
would report that it supported babel
, not babylon
, which breaks text-editor integrations. This has now been fixed.

TypeScript: Revert "Update typescript-estree to new package name" ([#5818] by [@ikatyang])
There's an internal change introduced in Prettier 1.16.2,
which updated typescript-estree
to its new package name,
but unfortunately it broke the output
so we reverted it as a temporary workaround for now.
// Input
export default {
load<K, T>(k: K, t: T) {
return {k, t};
}
}
// Output (Prettier 1.16.2)
export default {
load(k: K, t: T) {
return { k, t };
}
};
// Output (Prettier 1.16.3)
export default {
load<K, T>(k: K, t: T) {
return { k, t };
}
};

CLI: Fix CI detection to avoid unwanted TTY behavior ([#5804] by [@kachkaev])
In Prettier 1.16.0 and 1.16.1, --list-different
and --check
logged every file in some CI environments, instead of just unformatted files.
This unwanted behavior is now fixed.
HTML: Do not format non-normal whitespace as normal whitespace ([#5797] by [@ikatyang])
Previously, only non-breaking whitespaces (U+00A0) are marked as non-normal whitespace, which means other non-normal whitespaces such as non-breaking narrow whitespaces (U+202F) could be formatted as normal whitespaces, which breaks the output. We now follow the spec to exclude all non-ASCII whitespace from whitespace normalization.
(·
represents a non-breaking narrow whitespace)

JavaScript: Fix record type cast comment detection ([#5793] by [@yangsu])
Previously, type cast comments with record types were ignored and prettier stripped the subsequent parens. Prettier 1.16.2 handles these cases correctly.
<!-- prettier-ignore -->// Input
const v = /** @type {{key: number}} */ (value);
// Output (Prettier 1.16.1)
const v = /** @type {{key: number}} */ value;
// Output (Prettier 1.16.2)
const v = /** @type {{key: number}} */ (value);

JavaScript: Do not format functions with arguments as react hooks ([#5778] by [@SimenB])
The formatting added in Prettier 1.16 would format any function receiving an arrow function and an array literal to match React Hook's documentation. Prettier will now format this the same as before that change if the arrow function receives any arguments.
<!-- prettier-ignore -->// Input
["red", "white", "blue", "black", "hotpink", "rebeccapurple"].reduce(
(allColors, color) => {
return allColors.concat(color);
},
[]
);
// Output (Prettier 1.16.0)
["red", "white", "blue", "black", "hotpink", "rebeccapurple"].reduce((
allColors,
color
) => {
return allColors.concat(color);
}, []);
// Output (Prettier 1.16.1)
["red", "white", "blue", "black", "hotpink", "rebeccapurple"].reduce(
(allColors, color) => {
return allColors.concat(color);
},
[]
);
JavaScript: Add necessary parentheses for decorators ([#5785] by [@ikatyang])
Parentheses for decorators with nested call expressions are optional for legacy decorators but they're required for decorators in the current proposal.
<!-- prettier-ignore -->// Input
class X {
@(computed().volatile())
prop
}
// Output (Prettier 1.16.0)
class X {
@computed().volatile()
prop
}
// Output (Prettier 1.16.1)
class X {
@(computed().volatile())
prop
}
TypeScript: Stable parentheses for function type in the return type of arrow function ([#5790] by [@ikatyang])
There's a regression introduced in 1.16 that parentheses for function type in the return type of arrow function were kept adding/removing. Their parentheses are always printed now.
<!-- prettier-ignore -->// Input
const foo = (): (() => void) => (): void => null;
const bar = (): () => void => (): void => null;
// First Output (Prettier 1.16.0)
const foo = (): () => void => (): void => null;
const bar = (): (() => void) => (): void => null;
// Second Output (Prettier 1.16.0)
const foo = (): (() => void) => (): void => null;
const bar = (): () => void => (): void => null;
// Output (Prettier 1.16.1)
const foo = (): (() => void) => (): void => null;
const bar = (): (() => void) => (): void => null;
MDX: Correctly recognize inline JSX ([#5783] by [@ikatyang])
Previously, some inline JSXs are wrongly recognized as block HTML/JSX, which causes unexpected behaviors. This issue is now fixed.
<!-- prettier-ignore --><!-- Input -->
_foo <InlineJSX /> bar_
<!-- Output (Prettier 1.16.0) -->
_foo
<InlineJSX /> bar_
<!-- Output (Prettier 1.16.1) -->
