# use-static-qregularexpression Finds places such as ```cpp QString str = ...; if (str.contains(QRegularExpression(...))) { ... } QRegularExpression re(...); if (str.indexOf(re, 0)) { ... } ``` and suggests to use a `static` QRegularExpression object instead to avoid recreating the regular expressions. Note that it only checks for functions using `QRegularExpression` from `QString` and `QStringList`.
