What ever happened to this work? It was exciting and seemed valuable but never made it into Pharo. The traited collections \[1\] seemed particularly interesting and useful 1 https://www.researchgate.net/profile/Damien-Pollet/publication/45942931_BLO…

This week (25/2022) on the Pharo Issue Tracker
by Marcus Denker June 24, 2022

June 24, 2022

We merged 17 PRs this week. The main news is that DoIts that evaluate against a context (e.g. printing a value of a temp variable in the debugger) now use normal variables names (PR 9588). #DoItIn: is gone, as the parameter is not needed anymore (PR 11402) And PR#11379 enables IM support in SDL2: Some natural languages needs a support agent so-called IM to input letters/symbols including emojis.

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

Cheap/free Seaside site hosting (urgent)?
by lucasrodriguesoficial5＠gmail.com June 22, 2022

June 22, 2022

Hello there. Iâve just finished a website which, aside from a simple storage in Mongo/Voyage permanence layer, is otherwise very small and simple. But Seaside Hosting and Pharo Cloud are down, and international transactions are impossible in Digital Ocean. My country doesnât have any of the less complex cloud storages, making it all more difficult. At this point, Iâm willing to pay 17 dollars (max I have now) so that someone sets the image up for me at a DO droplet only once, as the app is technically static. This is urgent because the site is an effort to find a job (as a portfolio), and I donât have any additional money for nothing fancier. If no one can do that, what are the alternatives?

ESUG deadline for Presentation
by stephane ducasse June 3, 2022

June 3, 2022

Hi Happy Smalltalkers Two important points - We are starting to work on the program of ESUG 2022 and we will accept some more talks but do not wait too long. https://esug.github.io/2022-Conference/call2022.html <https://esug.github.io/2022-Conference/call2022.html> - The registration is open and the early rate is nicer than the late one :) https://registration.esug.org <https://registration.esug.org/> But you can sponsor ESUG by registering with late fees from 6th of July. But this is more expensive. S

Summary: SelectorTable improvements
by Marcus Denker June 3, 2022

June 3, 2022

Hi, Here is a short summary of all the improvements related to the SelectorTable (which allows the tools to quickly check if a symbol is used as a selector): - It is reset at image build (#cleanUp) - re-creating is fast (#bench shows '16.902 per second' on my machine for rebuildSelectorTable) (we can even think about resetting it on #shutDown: now) - Recording happens at method installation, not compilation - this means we call it far less on code loading - not called anymore for doIts and FFI method creation - optimized: #isSelectorSymbol is ~3.5 times faster in Pharo11 compared to Pharo10 - most speedup due to using a identity dictionary, avoiding costly string comparing - all users of #findInternedSelector: have been changed to send #isSelectorSymbol to the symbol - #findInternedSelector: will be deprecated Marcus
