[cl-who-devel] Double sexp tree traversal

[Slawek Zak]

Hi,

Is it necessary to walk the tree two times in cl-who?

CL-USER> (cl-who:with-html-output-to-string (*standard-output*)
       (:one (:two)))
 0[7]: (CL-WHO::TREE-TO-TEMPLATE ((:ONE (:TWO))))
   1[7]: (CL-WHO::PROCESS-TAG (:ONE (:TWO))
                              #<Function TREE-TO-TEMPLATE>)
     2[7]: (CL-WHO::TREE-TO-TEMPLATE ((:TWO)))
       3[7]: (CL-WHO::PROCESS-TAG (:TWO) #<Function TREE-TO-TEMPLATE>)
       3[7]: returned ("<" "two" ">" "</" "two" ">")
     2[7]: returned ("<" "two" ">" "</" "two" ">")
   1[7]: returned
           ("<" "one" ">" "<" "two" ">" "</" "two" ">" "</" "one" ">")
 0[7]: returned
         ("<" "one" ">" "<" "two" ">" "</" "two" ">" "</" "one" ">")
 0[7]: (CL-WHO::TREE-TO-TEMPLATE ((:ONE (:TWO))))
   1[7]: (CL-WHO::PROCESS-TAG (:ONE (:TWO))
                              #<Function TREE-TO-TEMPLATE>)
     2[7]: (CL-WHO::TREE-TO-TEMPLATE ((:TWO)))
       3[7]: (CL-WHO::PROCESS-TAG (:TWO) #<Function TREE-TO-TEMPLATE>)
       3[7]: returned ("<" "two" ">" "</" "two" ">")
     2[7]: returned ("<" "two" ">" "</" "two" ">")
   1[7]: returned
           ("<" "one" ">" "<" "two" ">" "</" "two" ">" "</" "one" ">")
 0[7]: returned
         ("<" "one" ">" "<" "two" ">" "</" "two" ">" "</" "one" ">")

I use version:
