PHEP: Compile-Time Literal Expression Syntax

by Daniel Slomovits

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

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

Hi Lucas, Put your image in a docker container hosted by Google cloud. If the container is less than 250MB, you can have free plan for a limited periode of time.

Cheap/free Seaside site hosting (urgent)?

by lucasrodriguesoficial5＠gmail.com

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?

Re: Problem installing pharo in my university

by tesonep＠gmail.com

Thanks, Jannik for the report. I have reproduced the problem and got the same results. Originally I had the same idea that Stef that the problem was with the machine code generation logic, but this logic is in the VM DLL and not in the executable, so it is not. I will do more tests to generate different versions of the VM to see if there is a problem of compilations or a piece of code that looks suspicious. I want to do a pass before reporting it as a false positive. I keep you updated.

I note you can report false positives to Kaspersky if the exe is not contaminated - https://support.kaspersky.com/viruses/answers/1870 Tim On Wed, 15 Jun 2022, at 12:00 AM, stephane ducasse wrote: > hello Jannik > > I hope that you are getting well.

Re: Problem installing pharo in my university

hello Jannik I hope that you are getting well. We can only support such installation :) Now I do not think that we ship the exe with a virus but we will check. The problem is that Pharo VM produces assembly code and probably that Kaspersky is thinking that this is a virus. I think that we will have to have a way to assess whether an installation is exactly the one we deliver.

Dear Pharoers, I want to install the stable version of pharo on all the computers of my academic component, but the IT Service has a problem with Kaspersky Security. It identifies a Trojanâ¦ Do you know this problem ? And how to install Pharo ? Best regards,
