 If you don't use multi option, you can use key, time, record parameter. The 2 following match directive is same:
 
     <match tag>
       type map
-      map ["code." + tag, time, {"code" => record["code"].to_i}]
+      map (["code." + tag, time, {"code" => record["code"].to_i}])
     </match>
     <match tag>
       type map
-      tag "code." + tag
+      tag ("code." + tag)
       time time
-      record {"code" => record["code"].to_i}
+      record ({"code" => record["code"].to_i})
     </match>
+
+Note: you have to wrap some configuration values with parenthesis like `("code." + tag)`, to avoid parsing by Fluentd itself.
