Global Functions

`getResolvedObjects (lst)` | `parser.t[485]`

Extract the objects from a list obtained with resolveNouns(). Returns a list composed only of the objects in the resolution information list.

`intersectNounLists (lst1, lst2)` | `parser.t[447]`

Intersect two resolved noun lists, returning a list consisting only of the unique objects from the two lists.

`spliceList (lst, idx, newItems)` | `parser.t[4538]`

splice a new sublist into a list, replacing the item at 'idx'

`tryAskingForObject (issuingActor, targetActor, resolver, results, responseProd)` | `parser.t[4556]`

Try reading a response to a missing object question. If we successfully read a noun phrase that matches the given production rule, we'll resolve it, stash the resolved list in the resolvedObjects_ property of the match tree, and return the match tree. If they enter something that doesn't look like a response to the question at all, we'll throw a new-command exception to process it.

`tryOops (tokList, issuingActor, targetActor, firstTokenIndex, cmdTokenList, cmdType)` | `parser.t[4336]`

Look for an undefined word in a list of tokens, and give the player a chance to correct a typo with "OOPS" if appropriate.

If we find an unknown word and we can prompt for interactive resolution, we'll do so, and we'll throw an appropriate exception to handle the response. If we can't resolve the missing word interactively, we'll throw a parse failure exception.

If there are no undefined words in the command, we'll simply return.

tokList is the list of tokens under examination; this is a subset of the full command token list. cmdTokenList is the full command token list, in the usual tokenizer format. firstTokenIndex is the index of the first token in tokList within cmdTokenList.

cmdType is an rmcXxx code giving the type of input we're reading.

`tryOopsMain (tokList, issuingActor, targetActor, firstTokenIndex, cmdTokenList, cmdType)` | `parser.t[4347]`

main "oops" processor
