So, while testing the new Roodylib code on old released code such as Kent Tessman's Spur, I came across things like Spur's "Little Jimmy" character where the object's/character's inventory is listed in the long_desc. The problem with that is that verblib.h (and my update to DoLook) still print a new line after the long_desc even if everything has already been listed and no object-content text is going to be printed.
Originally, I was going to make a post here about how the best solve for that is to make a before routine for the object for DoLook, have it run the long_desc and return true so the rest of DoLook is never called. Just as I was going to write the post here, though, I thought, eh, I'll take another look and see if I can fix DoLook since the before routine method sort of seems like weaseling out.
The good news is, I think I found a solution I'm generally happy with.
You may notice that the call to WhatsIn has an extra argument. Normally, WhatsIn goes through every child of the object and clears its already_listed attribute before going on to list things. I updated it so it does not do that step if the second routine argument is true (which is why DoLook has to clear already_listed before the object's long_desc property is even run).
This is how Little Jimmy's long_desc would look with the new code:
(Basically, the only change is that it marks the taffy as already_listed- of course, I probably should have moved it so it's only marked if Jimmy is holding the taffy, but in this case, it shouldn't affect anything.)
