! VERSION 5 - Adding a container to your game, functions, verbs, and death.
!
! In many cases you will want an object to be able to contain other objects.
! This may be as simple as creating a 'backpack' that will contain your school
! papers, apple, and pencil sharpener. In a more complex definition, a container
! could be a chasm, a bottomless pit, refrigerator, or a television.
!
! We're going to create a simple container and a complex container.
!
! The simple container is probably very familiar to you. It's a mailbox amd it's
! right here in front of the house. It contains a letter that can be read as well.

! Functions
!
! ----------------------------------------------------------------------------

!
! Added function ReadSub so that the property 'before' can use it. The default,
! if there is no 'before read', is to examine the object.
!
[ ReadSub; <<Examine noun>>; ];

[ TearSub; "You can't tear that"; ];

! ----------------------------------------------------------------------------
! Grammar
!
! The grammar section includes the file "Grammar" and will later include
! extensions to the standard grammar library.
!
! ----------------------------------------------------------------------------

Include "Grammar";

!
! We also have to extend the read grammar to call ReadSub
! by default.
!
! We're using the 'Extend' statment because the word "read" is already defined
! in the grammar file included above. This adds our usage.
!
! The 'first' tag is used to indicate to Inform that this usage of the word
! "read" should be the first one checked. Without 'first', the "read" word
! will not work the way we want it to because the default usage will get
! called and will not handle our code properly.
!
! 'legible' is the attribute we created and by placing it here, we're telling
! Inform that this attribute must be present in the object to call this usage
! of the word "read".
!
Extend "read" first * legible                       -> Read;

!
! We've also added the ability to 'tear' an object. Notice
! we had to specify 'noun' and then direct the default to
! TearSub.
!
! By the way, the 'Sub' is added on automatically by Inform.
!
! The word 'noun' tells Inform that the word "tear" must be followed by a
! noun, otherwise Inform will reply, "What do you want to tear?".
!
Verb "tear" * noun                                    -> Tear;
!
! Q: I'm really confused! Inform uses the words "first", "second", and "noun".
!    Can you explain the difference again?
!
! A: Sure.
!
!    'first' is a flag used in the grammar statement "Extend" so that the
!    new usage is called before previously defined usages. Without this
!    flag, an older usage might get called and your code may not work.
!
!    'second' is a variable that Inform sets if there is a second noun in
!    the player's statement.
!
!    'noun' is a variable that Inform sets if there are any nouns in the
!    player's statement. It gets set to the first noun found.
