Okay,

Using Frank's 4.4 trunk (update 12154) you can load Metacello-Base-dkh.98 from http://seaside.gemstone.com/ss/metacello and then use the Metacello Preview scripting API[1].

As reported earlier, there are still some test failures in MetacelloPreview 1.0-beta.32.2, but the fixes are to the tests and not the functional code base, so I'd say you can include Metacello-Base-dkh.98 in 4.4 at your leisure.

To load the basic Metacello functionality, you can use the Scripting API to load another configuration or execute the following:

  Metacello new
    configuration: 'MetacelloPreview';
    version: #stable;
    gemsource: 'metacello';
    load: 'batch'.

\to load the tests, exedute:

  Metacello new
    configuration: 'MetacelloPreview';
    version: #stable;
    gemsource: 'metacello';
    load: 'TravisCI'.

I'll release 1.0-beta.32.3 in a week or so, but I'll just update the #stable definition, so the above expressions should be used to guarantee that you're picking up the latest release...

| | | 
| | | For the nonce, how about we implement #removeKey:ifAbsent: (see
| | | Inbox), so we can at least unblock Dale?
| | |
