> Little Smalltalk 4 has only 54 classes
I just wonder how did they cheat !
According to the lab result FedEx just delivered.
Based on SqueakScript species, to have a truly minimal image
with just ProtoObject and Metaclass, the followings are also needed:
Array, Array class
ArrayedCollection, ArrayedCollection class
Behavior, Behavior class
Class, Class class
ClassDescription, ClassDescription class
Collection, Collection class
Dictionary, Dictionary class
Metaclass, Metaclass class
MethodDictionary, MethodDictionary class
Object, Object class
ProtoObject, ProtoObject class
SequenceableCollection, SequenceableCollection class
Set, Set class
String, String class
Symbol, Symbol class
UndefinedObject, UndefinedObject class
This is just the nucleus ( like a virus, no real life yet.)
A total of 32.
The lab also found that we also need to throw in
a mitochondrion to make it really alive.
62 more are needed :
Association, Association class
Bitmap, Bitmap class
BlockContext, BlockContext class
Boolean, Boolean class
ByteArray, ByteArray class
Character, Character class
ClassOrganizer, ClassOrganizer class
CompiledMethod, CompiledMethod class
ContextPart, ContextPart class
FakeSmalltalk, FakeSmalltalk class
False, False class
Float, Float class
IdentityDictionary, IdentityDictionary class
InstructionStream, InstructionStream class
Integer, Integer class
LargeNegativeInteger, LargeNegativeInteger class
LargePositiveInteger, LargePositiveInteger class
Link, Link class
LinkedList, LinkedList class
LookupKey, LookupKey class
Magnitude, Magnitude class
Message, Message class
MethodContext, MethodContext class
Number, Number class
Point, Point class
Process, Process class
PseudoContext, PseudoContext class
Semaphore, Semaphore class
SmallInteger, SmallInteger class
TranslatedMethod, TranslatedMethod class
True, True class
Out of these 62 extra, since the species does
not have a head, the following are questionable:
Bitmap, Bitmap class
Point, Point class
Did they drag along :
Float, Float class
LargeNegativeInteger, LargeNegativeInteger class
LargePositiveInteger, LargePositiveInteger class
And for a single free cell, is this needed:
Semaphore, Semaphore class
Before sending this result to "Natural Science",
I am asking for help from the list to verify that
the result is correct.
Just wondering how did 'Little Smalltalk 4' do it
with just 54 classes !
I want to create a liitle creature that just shows its heart
(what's the code for this from Character), and doing nothing else.
What do I need to put into the pot.
How do I make it tick, showing its heart.
(I met Harry Potter in the Chamber of Secrets
and he lent me his stirring rod ;-)
Can we trim down specialObjects ?
Did Little Smalltalk 4 cheat ? How ?
Your help is very much appreciated.
Cheers,
PhiHo.
