fix(formatter): Trim trailing whitespace before breaking line by leaysgur · Pull Request #19740 · oxc-project/oxc

leaysgur · 2026-02-26T06:27:22Z

This doesn't seem to be an issue with native js/ts format paths, but it appears to cause problems when converting Prettier Docs, such as with gql-in-js.

Without this change,

type Mutation {
    create__TYPE_NAME__(input: Create__TYPE_NAME__Input!): __TYPE_NAME__!
      @skipAuth

will be formatted:

type Mutation {
    create__TYPE_NAME__(input: Create__TYPE_NAME__Input!): __TYPE_NAME__! 
      @skipAuth

See trailing after __TYPE_NAME__!.
