可以设置代码行长度。但这也会影响注释行的长度，我不希望它受ColumnLimit的控制。
设置ColumnLimit后如何指定注释行长度？
答案 0 :(得分：2)
如果我正确理解您的注释，则表示将注释分成几行会阻碍其他代码分析程序的某些功能。在这种情况下，您可以为部分代码关闭并重新打开clang格式：
//i have stored my elements somehwere on a file as String
String disElement = "#sampleForm > fieldset > div:nth-child(1) > div.col-sm-5.col-md-6 > input"
assertTrue(WebDriver.findElement(By.cssSelector(disElement)).getAttribute("class").equalsIgnoreCase("read-only"));
