Yes, Iâm interested but would prefer the second half of June (our school is on the quarter system) and would prefer weekdays rather than weekends.

Pharo-vm mailing-list
by stephane ducasse July 2, 2022

July 2, 2022

Hi Since a couple of years the Pharo crew has been working on the Pharo-vm and most of the communication was using internal channels. Now that the community is growing we believe that it is important to have a public way to communicate around the VM and our current and future developments. We are happy to announce that we set up a mailing-list for the Pharo-vm. https://lists.pharo.org/list/pharo-vm.lists.pharo.org <https://lists.pharo.org/list/pharo-vm.lists.pharo.org> Stef on the behalf of the Pharo lille crew.

[Compiler API] unifying isScriping / isForScripting / isWorkspace
by Marcus Denker June 28, 2022

June 28, 2022

This is not directly the compiler API, but the API used by tools (e.g. requestors): There where three methods to test if the requestor operates on whole methods or not. - isWorkspace - isScripting - isForScripting This had lead to odd bugs in the past that something that was tested for one requestor failed if used in another context. (For that, we added both #isScripting and #isForScripting for some cases already). This Issue points to a series of PRs that unifies the situation: unify #isScripting and #isForScripting #9921 https://github.com/pharo-project/pharo/issues/9921 Note: it is not really possible to do this backward compatible in a nice way, but the good news is that this is an API used for tools that should not be used normally outside of the development tools themselves.

We merged 17 PRs this week.

PHEP: Compile-Time Literal Expression Syntax
by Daniel Slomovits June 23, 2022

June 23, 2022

Hello all, I have submitted a Pharo Enhancement Proposal <https://github.com/pharo-project/pheps/pull/10> for a new compiler/syntax feature, in collaboration with Marcus Denker. This is also serving as a trial run of the PhEP process itself, being the first PhEP not *about* the process. Abstract: This PhEP describes an extension to the compiler that allows arbitrary expressions to be evaluated at compile time, with the results stored in the method's literal frame. This is inspired by and will be compatible with the implementation in Dolphin Smalltalk. I refer to such expressions interchangeably as "compile-time literals", "compile-time expressions", and "optimized expressions". A large portion of the code can be ported directly from Dolphin Smalltalk, and I should be able to complete this part of the process. Marcus said he could help with the integration with OpalCompiler etc., but we can probably break this into several parts (compiler vs. decompiler, other peripheral things) if others are interested. I look forward to hearing what everyone thinks! Thank you, Daniel Slomovits

Compiler API: Simplify #interactive
by Marcus Denker June 22, 2022

June 22, 2022

The compiler has a lot of odd features as we wanted to be 100% backward compatible. One of them is the idea of the âinteractiveâ state. -> a compiler compiled with a requestor or without. -> Interactive use needs a requestor - to print error messages - to lookup variables The requestor can implement #interactive to return false. This is used to hook into error handling by implementing a fake requestor. MethodChunkCompilerRequestor is an example of that. But in addition, the compiler added âinteractiveâ as local state of the compilation context: you could make the compiler without a requestor Interactive, or turn off the compiler interactive even though the requestor was interactive. This makes no sense (and I think does not even work). This PR simplifies the idea of #isInteractive: if there is no requestor, we are not interactive. This means we do not need the flag "interactive" on CompilationContext and can simplify. For now we keep the feature that requestors can implement #interactive and return false, to support MethodChunkCompilerRequestor. I think we should simplify that, too, but that is another step. PR is here https://github.com/pharo-project/pharo/pull/11392 (And already merged) Marcus
