[Help-smalltalk] Does smalltalk-mode support old-style syntax?

[mmatalka]

Hello!

I'm trying to use Emacs to develop Smalltalk.  I am developing for Amber but 
GST seems to be the only place I can find a smalltalk-mode for Emacs.  The 
problem is I'm getting errors while trying to write code.  For example, if I 
create a file Foo.st and from an empty buffer write:

Object subclass: #Foo
instanceVariableNames

When I try to type ':' I get an error in the minibuf saying "At end of buffer" 
and I cannot type the ':'.

I was told that GST has switched to a new syntax, so is this valid for the said 
syntax?  If not, does anyone have any suggestions for an emacs mode that 
supports the chunk style?  Can I use the smalltalk-mode from an earlier version 
of gcc?  My workaround right now (which is less than ideal) is to comment out 
the lines that map : to smalltalk-colon and ! to smalltalk-bang.

Thanks,
Malcolm
