What is PharoJS ? Are you talking about Pharo on top of the Bert's SqueakJS

If so, it starts, but some primitives fail making it freeze after a short

There is no way of creating such blocks currently.
In fact only non local returns and debugging are problems as remote
variables are accessed through an indirection. A lightweight block (to
reuse your terms) with no outer context but accesses to remote temporary
variables would work fine.

The latest FFI uses the old VM FFI which works on x86 and ARM and a new

So OSSubProcess will work if you use FFI, but the old syntax not the new

Hello Sven,
You can use the VM with the JIT on the Pie now (Spur Cog VM). It is

Are you sure C++ compilation is the best way ? There are a lot of flaws:

you will loose debugging features, etc.

Ok.
Then I guess you can do something like Slang, which is used for the VM.
Slang is a restrictive Smalltalk compiling to C.
The slang compiler parses the code using the Smalltalk Compiler parser,
then translate the Smalltalk AST to its own AST, do some manipulation based
on pragmas available in

Hello,
As Stephan Eggermont said, you need to make some measurements.
There are a few big problems.
In short, if the FFI call is going to do quite some computation (at least a

you may get faster, if the FFI call is going to
sourceCode is the best way to do it. It answers the original sources if
available, and the decompiled sources if not available.

Alternatively, I do that using a SDL window. This way, the production game
can be launched using SDL and pharo headless, and not have the overhead of
the morphic rendering loop.

I think in addition of the parser/compilation chain, a language is about
having a good IDE.
The Pharo IDE depends more and more on the AST and not on the source code,
so if your new language uses an AST polymorphic with the Smalltalk AST I
guess you can have IDE tools for free (at least partly).
I usually get it from http://files.pharo.org/
In media, pharoCheatSheet or flyer-cheat-sheet.

On old versions of Pharo you need to use:

Hello Ben,
The limit you see for instance variables is due to:
- Class format encoding (Memory manager dependent)
- Bytecode set encoding (Bytecode set dependent)
The 255 inst var limit is enforced both by:
- the V3 Memory manager
- the SqueakV3PlusClosures bytecode set.
Now we have Spur instead

General documentation on all the base frameworks is present in the *Pharo

Or here for the updated version:

Thanks for reporting the problem.
The error means the VM is incompatible with the image. There was a change
of image format in Pharo 5, so the package has likely an old VM while the
image has the new format, or the new VM while the image has the old format.
Someone will look into that problem in

The VM you use is the fastest one available.
It's slower mostly due to non Smalltalk concerns (processor architecture,
energy consumption, frequency, overall hardware).

If I am correct, when you do:

is using SmallInteger operations. The code you wrote is fully inlined in

Not really.
You can use ClassVariables though. Here's an example for Sets:

MyClassVar := Set new.

Using ClassVariable is an alternative way to shorten object initialization,
