--parser babelInput:
// Prettier does not automatically wrap.
const myLongVariableName = /** @type {ThisIsAVeryLongTypeThatShouldTriggerLineWrapping} */ (fooBarBaz);
function jsdocCastInReturn() {
return /** @type {ThisIsAVeryLongTypeThatShouldTriggerLineWrapping} */ (fooBarBaz);
}
// Prettier wraps but add a newline, just because there's a trailing whitespace.
const myLongVariableName = /** @type {ThisIsAVeryLongTypeThatShouldTriggerLineWrapping} */
(fooBarBaz);
function jsdocCastInReturn() {
return (/** @type {ThisIsAVeryLongTypeThatShouldTriggerLineWrapping} */
(fooBarBaz));
}
// Prettier correctly formats and wraps the lines.
const myLongVariableName = /** @type {ThisIsAVeryLongTypeThatShouldTriggerLineWrapping} */
(fooBarBaz);
function jsdocCastInReturn() {
return (/** @type {ThisIsAVeryLongTypeThatShouldTriggerLineWrapping} */
(fooBarBaz));
}Output:
// Prettier does not automatically wrap.
const myLongVariableName = /** @type {ThisIsAVeryLongTypeThatShouldTriggerLineWrapping} */ (fooBarBaz);
function jsdocCastInReturn() {
return /** @type {ThisIsAVeryLongTypeThatShouldTriggerLineWrapping} */ (fooBarBaz);
}
// Prettier wraps but add a newline, just because there's a trailing whitespace.
const myLongVariableName =
/** @type {ThisIsAVeryLongTypeThatShouldTriggerLineWrapping} */
(fooBarBaz);
function jsdocCastInReturn() {
return (
/** @type {ThisIsAVeryLongTypeThatShouldTriggerLineWrapping} */
(fooBarBaz)
);
}
// Prettier correctly formats and wraps the lines.
const myLongVariableName =
/** @type {ThisIsAVeryLongTypeThatShouldTriggerLineWrapping} */
(fooBarBaz);
function jsdocCastInReturn() {
return (
/** @type {ThisIsAVeryLongTypeThatShouldTriggerLineWrapping} */
(fooBarBaz)
);
}Expected behavior:
prettier should automatically add new lines to wrap long constructs when using JSdoc casts, rather than having to manually add a line break. Also note that if you keep a trailing whitespace, prettier adds an extra new line.
