Input Pug

doctype html
p(hello="there" {{extra-attributes}}) hey

Expected HTML

<!DOCTYPE html><p hello="there" {{extra-attributes}}>hey</p>

前置要求: Knowledge of Pug templatingJavaScriptLexer parsing basics
新手友善度: 70
研究方向: Investigate the `attrs` function in `pug lexer/index.js` starting around line 1089 where the error is thrown. The issue occurs when interpolated attributes (using `{{...}}`) appear after normal attributes. Compare the parsing logic for different orders. Check how the lexer differentiates between attributes and expressions. The fix likely involves adjusting the regular expression or parsing order to handle `{{...}}` in any position.
