[ANN] Fuel 5.0.0

by Max Leske

Hi everyone, I'm happy to announce Fuel version 5.0.0 today. The changes to 4.0.0 aren't huge but I've had to adjust the format once more. 5.0.0 comes with full support for stateful traits, i.e. traits with instance variables. You can find the release notes here: https://theseion.github.io/Fuel/releases/5.0.0/. Cheers, Max (on behalf of the Fuel team)

[ANN] Pharo Oracle Call Interface

by Sven Van Caekenberghe

Hi, Pharo Oracle Call Interface (https://github.com/Ironirc/Pharo-Oracle-Call-Interface) is a new project that is currently under development. It was started and implemented by Ivo Roefs. This library allows you to connect to an Oracle SQL RDBMS from Pharo (versions 8 and up). It provides a binding with Oracle's OCI (also known as the Oracle Call Interface) using FFI. Usage Once correctly installed on your local computer, you use OciClient to interact with the Oracle database: | client rows | client := OciClient new environmentString: 'pharotst202112_medium'; username: 'SCOTT'; password: 'TIGER'; yourself. rows := client query: 'SELECT * FROM emp'. client close. rows. Installation To install this library you clone the repository and load BaselineOfPharoOracleCallInterface. This can be done using the Iceberg UI tools or with the following script: Metacello new baseline: 'PharoOracleCallInterface'; repository: 'github://Ironirc/Pharo-Oracle-Call-Interface:main/'; load. You have to make sure that the Pharo VM can access/load the necessary native library for your client side OS platform. The easiest way to get started is using Oracle Instant Client and an Oracle Cloud account. You also have to set up and configure access, contact your DBA for help. Status This project is new and currently under development. It should not be used for production applications. Basic queries are working on 32 and 64 bit Windows and 64 bit macOS. We are looking for collaborators, fellow developers who can help. Ivo & Sven

Re: Talents - VM Crash on P9 after Fuel Materialization

Re: PTerm - Can't Find FFI Library on M1 Mac on P9

by Max Leske

Hey Sean, I can get a terminal to open (with a bit of manual intervention) and I can type some characters. So FFI calls appear to work but the application is pretty broken on P9. This is on a x86 MacBook Pro. Simply added the repo in Iceberg and loaded the baseline.

PTerm - Can't Find FFI Library on M1 Mac on P9

by sean＠clipperadams.com

The really cool PTerm in-image terminal emulator works for me in P8 but not on P9. I recently upgraded to an M1 Mac, so Iâm trying to isolate whether ARM is the cause of the problem. Can someone try to reproduce the issue described here: [https://github.com/lxsang/PTerm/issues/20](https://github.com/lxsang/PTerm/… "https://github.com/lxsang/PTerm/issues/20") TIA, s

Talents - VM Crash on P9 after Fuel Materialization

by sean＠clipperadams.com

After serializing and then materializing an object with a talent, the trait's instVar seems to have disappeared from the inspector, although the print string looks like that of a Talented object. If you send a getter for a talented ivar, Pharo crashes. Not sure if this is a Talents problem or a Fuel problem (or both). More details and reproducible steps here: [https://github.com/tesonep/pharo-talents/issues/11]( https://github.com/tesonep/pharo-talents/issues/11 " https://github.com/tesonep/pharo-talents/issues/11") Anyone have some insight?\ \ I reported on Jan 7, but maybe more eyeballs here. Iâve been eager to give Talents a real try, but use Fuel extensively, so this is a blocking issue for me.
