Plus... Lots of classes and routines that help representing AE objects,
|
||||
ranges, conditionals, logicals, etc., so you can write, e.g.:
|
||||
|
||||
x = Character(1, Document("foobar"))
|
||||
x = Character(1, Document("foobar"))
|
||||
|
||||
and pack(x) will create an AE object reference equivalent to AppleScript's
|
||||
|
||||
character 1 of document "foobar"
|
||||
character 1 of document "foobar"
|
||||
|
||||
Some of the stuff that appears to be exported from this module comes from other
|
||||
files: the pack stuff from aepack, the objects from aetypes.
