Hello anyone, I have a simple problem, but I can't find an elegant solution. Basically I have a message and two flags, the first one signals message should be rendered in <strong> tag and the second - in <italic>. So there are four possibilities. Here is the actual code: (defmethod p-render-html ((s-tree tree) (p text-piece) s) (with-html-output (s nil :prologue nil) (let ((style (style-of p)) (txt (text-of p))) (if style (if (tree-find-prop s-tree style #'bold) (htm (:strong (if (tree-find-prop s-tree style #'italic) (htm (:italic (str txt))) (str txt)))) (if (tree-find-prop s-tree style #'italic) (htm (:italic (str txt))) (str txt))) (str txt))))) I had to test for each case and it resulted in code duplication. Can it be avoided? What if I had 5 flags or so?
