Ah yes, and I���ve done this so far on Pharo6.1, platform where Eliot was working on initially.

I don���t think there is much to do to move it to Pharo7, but still I���ve not explored it.

Hi all,

Just to keep everyone informed, last week I���ve spent a couple of days making slang work on Pharo again, based on the initial effort of Eliot.

The summary of what I did is:

��- we can generate, compile and run a stack vm

��-��we can generate, compile and run a cog vm

��- for this, I���ve done a couple of patches to VMMaker

�� - the ones specific to Pharo has been pushed

�� - the ones that touch cross dialect code are still in review (I think)��

To do this work��

��- I had to review the AST-to-AST transformation, checking the output, comparing it to what squeak does and so on...

��- I���ve written several unit tests to ensure that future migrations are easier to do

��- I���ve introduced several compatibility classes/methods related to PackageInfo, Time and so on���

Cheers,

Guille

I've decided for the moment to put the tests in the PharoCompatibility package, since they are too close of Pharo's AST.

I've tried to make them work in squeak but I've found too many incompatibilities in the AST and some in the collections that would make the tests too verbose to make them reusable...

Maybe we can do an iteration afterwards.

Cheers,

Guille

Sure. I've submitted another version to the inbox:

Name: VMMaker.oscog-GAP.2534

Author: GAP

Time: 9 May 2019, 5:12:22.055089 pm

UUID: cd6aae16-6f20-4ddb-9328-64b19b413cb1

Ancestors: VMMaker.oscog-eem.2532

Convert numeric constants to strings for concatenation using #printString.

Required for Pharo compatibility, where the arguments of concatenation are not automatically coerced to strings.

Guille, if you want commit access to the repo, you can make an account
on source.squeak.org and I'll add you the the VMMaker project. Or if
it's easier, just say which packages you are ready to move and either
I or Eliot (or any of the others with commit access) will move it to
VMMaker for you.

I note that VMMaker.oscog-GAP.2533 package is part of the main
VMMaker.oscog package. If you need to have that tested on Squeak I
can probably do that for you within the next couple of days if no
one else gets to it first.

Well, the change I did in that package was fairly small, and I'm using squeak to generate also some parts of the VM to compare to what I generate from Pharo.

So, I'd say I've tried it myself already.

For the Pharo specific package, I've already uploaded it to the VMMaker repository.

I had already rights to do it :).

Ancestors: VMMakerCompatibilityForPharo6-GuillermoPolito.10

With these changes I can already compile and run Cog and almost all tests pass :)

I have also a couple dozen tests about AST translation and C generation, mainly about those parts that are covered differently between Pharo's and Squeak's ASTs.

Would you like that I push them inside the VMMaker package or make a separate package?

Thanks!

Guille
