I've got an amusing contradictory anecdote for this. I wrote my MUD
parser to properly handle

However, it did NOT handle get 2.sword -- I'd never used it before,
so didn't think to implement it. Most of our active players are
first-time MUDders, and they found the second/2nd form
intuitive. However, one of our players had MUDded before, and
expected it to work:

So even if it strikes you as "messy," you may find that players will
expect it to work anyway, proper English or not. When I responded that
the player should try "second tree" instead of "2.tree". She said she
hadn't thought of that, and would try it.
Perhaps this goes some way to answering the original question -- MUD
parsers are written the way they are because players expect them to be
written the way they always have been.

Rusalka multiple trees 2004-01-25 00:53:33
I just noticed that whilst standing in a room with an empty banana
tree and an apple tree, I can only pick from the (first) empty
banana tree. I tried picking from the apple tree but that doesn't
seem to be working.
One way to get around this might be to designate subsequent trees
as "2.tree," "3.tree," and so forth. Then I could "pick apple from

Did you try 'pick apple from second tree'? You can also abbreviate
it pick apple from 2nd tree; You can also do 'pick apple from
nearest tree', 'pick apple from furthest apple tree', and even
silly things like 'pick apple from second furthest apple tree'.

Malap syntax 2004-01-26 14:52:38
The #.noun syntax is well-established on muds and worth
supporting. I remember looking into it once a few months ago; a
wizard (I forget who) asked to check something out for them, and I
forgot all about it until seeing Rusalka's post.

Acius #.noun syntax 2004-02-10 02:01:36
OK, all present should now honor this syntax. In the process, I
rooted out a rather ugly little bug where "get 2nd pine cone"
would get "two pine cones", because pine cones are a stackable
object. It was a fairly obscure bug, but it's fixed anyway...
This thread has died now, I think, and I'm going to make another
attempt to close it ;-)

Didn't think of that; will try it! Thanks!
