starting specific image in one-click Pharo?

How does one choose to use a different image in Pharo, at least on a Mac?

I can't find a preference setting or menu option to load an earlier
version, though I can go into the .app directory and manually start a
specific image.


Also, is there any way of working with different versions of the same
package/classes in the same image?

In other words, if I want to follow two different development paths,
could I "sandbox" versions of package(s) in different projects and
automatically switch between them when I switch projects?

Or is there some other way of accomplishing this? The most obvious route
is to reload or at least choose an image during the startup process, but
I don't see how to even do that.

Thanks.

The one click image is a bundle.
        u can open the bundle and change the image
Now I suggest you install the vm and you double on your image.
I do not use the oneclick because the package cache is inside and because I cannot decide what I execute easily

it should be easy to create an applescript shell that would launch first
and let you choose which image you wanted to start with. Maybe some
other command line parameters could be selected at that point also?


I'm not sure what you mean about the package cache though. Does the VM
use the cache in the .app directory differently than when it appears it
the regular directory?

probably but not for me.
If you have it and it works we will happily include it.

Mc creates a cache close to the image.

You'd probably want to truncate the changes after startup once in a
while doing that though, both because I don't think 1.0 had the changes
for .changes file > 32MB, and there'd be less to wade through if you had
to recover lost changes some time.

Not sure how to set the default behavior to call that script when the
icon is double-clicked nor how to hide unwanted file names but it sorta
works :-/.

How is this a problem. Is there a way to chose the files to use?
