Thank you. I thought the pharo vmbuilder way is only for cog-vms, and the traditional way
for the interpreter vm would still work.
There is a vmmaker chapter at

Hi Nicolai,

Question1

The Primitives you mention is a class variable.
Put your cursor on it and hit the blue "C" button on the right of the Nautilus code pane to see where it is used.

You'll notice that it is initialized in DiskStore class>>useFilePlugin

useFilePlugin
��� Primitives := FilePluginPrims new

FilePluginPrims in turn provides an interface to the real file plugin.

e.g.
FilePluginPrims >> size: id
��� "Answer the size of this file."

��� <primitive: 'primitiveFileSize' module: 'FilePlugin'>
��� self primitiveFailed

So, class variables are WrittenLikeThis and you may thing that it is a class. But it is either a class variable or a global (e.g. Display, Transcript)

In a workspace, try: Display class <printIt> Transcript class <printIt>

You'll see the real classes.

When using spotlight for example, you'll never find anything if you type Display for example. Even if the completion will propose something to you (hey, someone fixing this?)




Question2

If you want to load VMMaker, you have to do it from the GitHub directions.

There is a step where you do:
cd image && ./newImage.sh
and it loads all you need and you end up with the generator image.

I've been using it in my fork https://github.com/philippeback/pharo-vm
and the canonical repo is https://github.com/pharo-project/pharo-vm

Follow the directions of the README.md and you'll be ready with ease.
If you use OSX, it is working very smoothly.
Windows will require some more fiddling but there is nothing stopping you.

The generator already has VMMaker in.

Now, please bear in mind that the PharoVM isn't the same VM as Squeak uses, so, the process is not with the Morphic based VMMaker tool (green thing) where you select plugins etc.

Here, you are going to use the PharoVMBuilder which does all of the automation.
./pharo generator.image eval 'PharoVMBuilder buildWin32'
will generate all CMake files, all Slang based files etc.

I plan to do a video of all the steps very soon. This will help.

Now, the VMSimulator isn't fully operational in the PharoVM, I am working on getting it right.
At this point, it executes bytecodes without problems, but we need to port some more code to the new transcript, filesystem etc.
Just a question of doing it. I am looking at that, hopefully� this will work in december.


Hope this clarifies the situation for you.

Enjoy,
Phil

What is this "Primitives" not a class? I am suprised there is some code
that I can not find the source for.

Ok, it has something to do with vm primitives, and I know that code like
<primitive: 'primitiveDirectoryEntry' module: 'FilePlugin'>
is in the vmmaker-package for FilePlugin.

BTW it is terrible hard to load vmmaker in a "normal" image. Now I use
the generator.image from pharo http://files.pharo.org/vm/src/.
But even in this image it is not possible to load the vmmaker tool.
