BaselineOfZincHTTPComponents>>baseline:
by Alistair Grant Jan. 10, 2020

Jan. 10, 2020

Hi Sven, Following on from a discussion I started in Discord development... Loading Zinc SSO in Pharo 8 currently causes problems because the Zinc packages in core Pharo 8 are out of sync with your repository (specifically https://github.com/pharo-project/pharo/commit/45b7de2b6c901112be04230faba48… caused problems for me). I was able to resolve the issue by modifying BaselineOfZincHTTPComponents>>baseline: to remove all references to the packages that are now part of core Pharo 8: BaselineOfZincHTTPComponents>>baseline: spec <baseline> spec for: #common do: [ spec baseline: 'NeoJSON' with: [ spec repository: 'github://svenvc/NeoJSON:v17/repository' ]. spec baseline: 'XMLParser' with: [ spec repository: 'github://feenkcom/XMLParser:v0.6.1/src' ]. spec baseline: 'XMLWriter' with: [ spec repository: 'github://feenkcom/XMLWriter:v0.6.0/src' ]. "spec project: 'XML Support' with: [ spec className: 'ConfigurationOfXMLSupport'; repository: 'http://www.squeaksource.com/MetacelloRepository' ]." spec package: 'Zinc-AWS'; package: 'Zinc-REST' with: [ spec requires: #('NeoJSON') ]; package: 'Zinc-WebSocket-Core'; package: 'Zinc-WebSocket-Tests' with: [ spec requires: 'Zinc-WebSocket-Core' ]; package: 'Zinc-SSO-OAuth1-Core' with: [ spec requires: #('NeoJSON') ]; package: 'Zinc-SSO-OAuth2-Core' with: [ spec requires: #('NeoJSON') ]; package: 'Zinc-SSO-OpenID-Core'; package: 'Zinc-SSO-Demo' with: [ spec requires: #('Zinc-SSO-OAuth1-Core' 'Zinc-SSO-OAuth2-Core' 'Zinc-SSO-OpenID-Core') ]; package: 'Zinc-SSO-OAuth1-Tests' with: [ spec requires: #('Zinc-SSO-OAuth1-Core') ]; package: 'Zinc-SSO-OpenID-Tests' with: [ spec requires: #('Zinc-SSO-OpenID-Core') ]; package: 'Zinc-WebDAV'; package: 'Zinc-WWS-Server'; package: 'Zinc-WWS-Client'. spec group: 'AWS' with: #('Zinc-AWS'); group: 'WebDAV' with: #('Zinc-WebDAV'); group: 'WebSocket' with: #('Zinc-WebSocket-Core' 'Zinc-WebSocket-Tests'); group: 'SSO-OAuth1' with: #('Zinc-SSO-OAuth1-Core' 'Zinc-SSO-OAuth1-Tests'); group: 'SSO-OAuth2' with: #('Zinc-SSO-OAuth2-Core'); group: 'SSO-OpenID' with: #('Zinc-SSO-OpenID-Core' 'Zinc-SSO-OpenID-Tests'); group: 'SSO-Demo' with: #('Zinc-SSO-OAuth1-Core' 'Zinc-SSO-OAuth2-Core' 'Zinc-SSO-OpenID-Core'); group: 'SSO' with: #('SSO-OAuth1' 'SSO-OAuth2' 'SSO-OpenID' 'SSO-Demo' 'Zinc-SSO-Demo'); group: 'WWS' with: #('Zinc-WWS-Server' 'Zinc-WWS-Client'); group: 'REST' with: #('Zinc-REST') ] This isn't directly usable by you since it replaces 'XML Support' with XMLParser and XMLWriter and it would break Pharo 7. But if we modified it to put in checks for Pharo 7 vs Pharo 8 it would somewhat future proof the code against changes made in core Pharo 8. What do you think? Thanks, Alistair

[ANN] Sysmel, another experimental low-level language implemented in Pharo
by Ronie Salgado Jan. 10, 2020

Jan. 10, 2020

Hi All, I am finally announcing an initial release of my new experimental low-level programming language which I am calling Sysmel (For SYStem MEtaprogramming Language). GitHub Page: https://github.com/ronsaldo/sysmel Short native game demo: https://www.youtube.com/watch?v=tRoPMbPvqH0 Sysmel is designed to be a flexible language, and a flexible compiler front-end. The support for garbage collection in Sysmel is an optional feature by design, and the support for dynamic objects and dynamic message lookup it is also optional. If garbage collection is disabled, the code written in Sysmel is mostly equivalent to C/C++ code (only single inheritance is supported for now), but with a hybrid syntax between Smalltalk and C++. For the final code generation I am using my custom SSA intermediate representation (the same one that I used in Lowtalk, and in) which it is currently tested with the following two backends: - LLVM textual IR backend. This is used for generating native object files by reusing the LLVM infrastructure. This backend also supports emitting DWARF debugging information so the resulting programs can be debugged with gdb. - Spir-V backend, for generating shaders for Vulkan and executing them in the GPU. One of the objectives of Sysmel is to support the full Smalltalk object model without a VM and with real multi-threading support. So far message lookup is already implemented, but there is still many basic primitives missing, and the implementation of a proper GC that allows implementing #allInstances and #become: . As a quick workaround, currently only the Boehm conservative GC is supported for having an initially working environment. In the near future, Woden Engine will adopt Sysmel at least as its shading language for programming the GPU. In a farther future, a higher performance version of the Woden Engine will be made by using Sysmel, mostly because it seems to be much easier to support real multi-threading in Sysmel by making a completely new system. I am also re-implementing my previous experiment for converting Pharo block closures into shaders by reusing the Sysmel intermediate level AST, and its type inference machinery. The current version of this new Block -> to Shader infrastructure can only perform basic Map and Reduce operations with blocks that do not define local variables (they will be supported in a future version) in linear arrays. Best regards, Ronie

In pharo 7, inspecting: 1.0e3333 gives: "Reading a number failed -> " it works for: 1.0e333 (only three "3") is that the expected behaviour ? nicolas -- Nicolas Anquetil RMod team -- Inria Lille

Pharo key features (document)
by Pavel Krivanek Jan. 6, 2020

Jan. 6, 2020

Hi, I have created a list of the key Pharo features with some images and animations that should help to explain to public what is cool on Pharo. It is based on a list formerly created for a Wikipedia article. https://github.com/pavel-krivanek/pharoMaterials/blob/master/features/Pharo… Please look at it to check if something is worth to add or change before we will try to use it somewhere for real. Cheers, -- Pavel
