[squeak-dev] Cuis-Squeak portability.

If I file out Collections-SkipLists from Cuis (1.0) and try to file in the
result to Squeak (3.10 beta), I get an error:

Nothing more expected ->classDefinition: #SkipList category: #'Collections-SkipLists'

Skip lists is just an example; filing in to Squeak from Cuis doesn't work for
anything I tried. This is broken, right?

Squeak change sets do class definitions via doits. In addition to the
doIt, Cuis supports a new type of change, ClassDefinition. But the doIt
is also generated.
So what you need to do is to remove those changes that start 'preamble:
classDefinition'. After that, everything should work ok.

In unix talk,

$ sed 's/!classDefinition:[^!]*!//g' < cuis.st > squeak.st

$

did the trick. Thanks.

How do you mean that? It is just a line with invalid syntax in a file that
pretends to be part of the Smalltalk world (ya know: receiver and message
selector and things). Example generated by Cuis:

!classDefinition: #Imports category: #'System-Support'!

Wouldn't it be easier to stick with the Smalltalk way of formulating
messages, like

!nil classDefinition: #Imports category: #'System-Support'!

and then supply an implementor of #classDefinition:category: which is also
good documentation (ya know: alt-m and alt-W and things).

?

In Squeak, change sets support several types: #method, #classComment,
#doit, #preamble. I don't like #doIts because a ChangeList can't do
'remove up-to-date versions' with them. So I just added
#classDefinition. Some day I'd also add #methodRemove and #classRemove
for the same reasons.
