This was how all Smalltalkers worked in the 80s. OTI created Envy to
improve the situation, and Cincom eventually replaced Envy with Store,
and of course Squeak got Monticello. There is a good reason why
people built these systems; change sets can be a pain in the neck.
But it is possible to manage version control with change sets, it just
takes some discipline. E-mail is NOT advised as the main way of
sharing. You need to have a shared file system. You must keep a list
of all the change sets and the order they are to be filed in. When
you want to "commit a change", you not only put your change set in the
repository, you add it to the list of change sets to be filed in.
On my first big Smalltalk project, our list of files was embedded in a
Smalltalk script that acted like a makefile. We'd execute this script
and it would file in all the change files and so build an image for
Another thing is that we named our change sets something like
"Modulename-author-date.st" to ensure that two people didn't make
files with the same name, and to give a hint at the order they would
be filed in, though there were a few cases where we did not file them
in by date order.
