[squeak-dev] SyntaxError while loading FFI

Hi Eliot, hi all.

We had the discussion about the role of Installer recently on the list. After fixing Metacello (and the script for FFI), the wizard will likely to use "Metacello new configuration: 'FFI'; load." again to manage support for different Squeak versions.

Here is the discussion about the future of "Installer":

Loading FFI via the Preference Wizard -- which uses the Installer directly -- works fine in current (fresh) trunk. No debuggers to confirm. No syntax error.

That's good to know.  I'll alter my VMMaker image build scripts to use this.  But there's one code smell about this.  PreferenceWizardMorph is a morph.  i wonder if it's worth-while separating PreferenceWizardMorph into PreferenceWizardMorph and PreferenceWizard.  It feels better changing the script to read PreferenceWizard new installFFI than having it rad PreferenceWizardMorph new installFFI.  If you agree that this is OK, I can make the changes.

Hmmm, maybe better is to move these install scripts to the Installer hierarchy.  Not sure where they should live.  But it would be nice to be able to say 
    Installer installFFI
and have it choose a default path, as well as be able to say
    Installer squeak installFFI
and have it install via InstallerMonticello


I am updating that Metacello script right now. Be patient. :-)


Best,
Marcel

Hi Jakob,

do you have a description of the correct loading order? In my main image, I tried to load FFI via the Preference Wizard, and after some loading conflicts which I explicitly needed to #allow through the debugger, I got the same syntax error ...

Christoph

Hi Christoph,

I had a similar issue and if I remember correctly got it resolved by
loading the Tools subpackage of FFI. I think Marcel has recently split
it.

So if that is true, the load order in the baseline of FFI should be updated.

Kind regards,
Jakob
