Pharo on Emscripten (WebAssembly)
by Pavel Krivanek March 8, 2021

March 8, 2021

Hi, I just want to note that in 2019, I tried to build a Pharo VM to WebAssembly using Emscripten. It was not really working but I was able to, at least, build and run the VM. [image: EmPharo.png] The code is here: https://github.com/pavel-krivanek/EmPharo Maybe someone will be interested enough to try to push it :-) The main issues I found: - the VM seems to use the long jumps and in very ugly way - it specifies assembler labels and then it jumps to them - heartbeat - atomic operations (probably not so critical) Cheers, -- Pavel

Progress Report -> Refactoring Project - ( February 8 - 12 )
by Evelyn Cusi Lopez Feb. 24, 2021

Feb. 24, 2021

Hi all Last week I did these tasks: - Add preview to select variables when running the generate accessors command (Fix issue #5270 <https://github.com/pharo-project/pharo/issues/5270>). - Separate the link between views and refactorings (setUp and pushDown method refactoring). - Add generic previews and remove specific previews of PushUp and PushDown refactoring (https://github.com/pharo-project/pharo/pull/8553) - I started the modification to make refactorings only in some packages, add a searcher for classes and methods in packages (these have reference to the package internally), I still have to finish implementing this part so that it is updated correctly when there are changes, deletions and additions. Fix issues #8513 <https://github.com/pharo-project/pharo/issues/8513>, #6366 <https://github.com/pharo-project/pharo/issues/6366>. - Improve "Move method to class side" Refactoring, the new version catch broken references (method senders and direct access to instVar) and fix them ( https://github.com/pharo-project/pharo/compare/Pharo9.0...Lin777:NewMoveToC…) for instance: Before refactoring: *RBTransformationRuleTestData* >> rewriteUsing: searchReplacer rewriteRule := searchReplacer. self resetResult. After refactoring: *RBTransformationRuleTestData* >> rewriteUsing: searchReplacer ^ self class rewriteUsing: searchReplace. *RBTransformationRuleTestData* *class* >> rewriteUsing: searchReplacer | aRBTransformationRuleTestData | aRBTransformationRuleTestData := self new. aRBTransformationRuleTestData rewriteRule: searchReplacer. aRBTransformationRuleTestData resetResult'). ----------------------------------------------------------------------- Tasks for this week: - Improve extract setUp refactoring. - Finish to rename methods in specific packages (Fix issues #8513 <https://github.com/pharo-project/pharo/issues/8513>, #6366 <https://github.com/pharo-project/pharo/issues/6366>.) - Improve messages when exists a Warnings or Expections in refactorings. - Fix move to component refactoring issue ( #8499 <https://github.com/pharo-project/pharo/issues/8499>) - Fix extract method issue (#5855 <https://github.com/pharo-project/pharo/issues/5855>) - Check if it is better to change the behavior of the "Remove method" command, using a refactoring instead of a strategy Cheers, Evelyn

Hello happy Pharoers Today we could access our building where the M1 machine is and Pablo packaged it so that you can test the first version. Pablo wrote a little blog post for you. https://thepharo.dev/2021/02/16/first-apple-m1-pharo-version/ Let us since we do not have the M1 at hand and waiting to be able to make it accessible from our build farmâ¦ but we are not responsible for it and we were waitingâ¦. But the crew was fixing other VM glitches. So we will be ready soon to focus on the Jit version.
