<p><font face="Georgia">Well, #</font>initKnownRenames<font
face="Georgia"> came after my involvement, but there are several
options available here:</font></p>
<p><font face="Georgia">- #</font>initKnownRenames can specify a
class to be substitued for another encountered in the input
stream, whether the class in the stream exists in the image or
not. So, you can just create something different if you like.</p>
- #multiNewParagraphttfclpomsswfpp0, etc. (in SmartRefStream))
allows specific versions (all the ttfcl... stuff) to be substituted
with something different.<br>
<br>
- #convertToCurrentVersion:refStream: (in various classes) allows
newly created instances to get their inst vars modified to current
standards, like if 'name' used to be a String and now it's a Name,
you might use this to fix old instances that still have Strings<br>
<br>
So, if the issue is about fixing paragraphs or projects coming in
from a ref stream, then #convertToCurrentVersion:refStream: will
probably let you do what you want.<br>

Seems to be the regular way to do this whereas
SmartRefStream>>initKnownRenames
looks more like a hack. However it is not etoys specific as it is
present in Squeak 5.0 (screen shot)
#initKnownRenames is called in
SmartRefStream>>initShapeDicts
It has a flag #bobconv
Looks like unfinished business. Bob, what would you see as the way forward?
initShapeDicts
"Initialize me. "
self flag: #bobconv.
"These must stay constant. When structures read in, then things can change."
steady := {Array. Dictionary. Association. ByteString. SmallInteger.
Character} asSet.
renamed ifNil: [
renamed := Dictionary new. "(old class name symbol -> new class name)"
renamedConv := Dictionary new "(oldClassNameSymbol ->
conversionSelectorInNewClass)"
].
self initKnownRenames
