Pharo 9 arbitrarily changes temporary variable names
by Robert Briggs Dec. 28, 2021

Dec. 28, 2021

Hi I define temporary variables in a method, e.g. |e r |, e.g. in a unit test, but when I run the test Pharo automatically replaces these with | tmp1 tmp2 |. A similar thing happens with method arguments.Â For example methodName: aString at: anInteger will become methodName: arg1 at: arg2. This has happened through my entire model, not just as described above.Â What is going on.Â Is it a bug, or is there a setting that needs to be changed? Many thanks for any feedback on this. Regards Robert Briggs

Pharo9: Lessons in "Learn Pharo" are now black and unreadable
by hedley.finger＠gmail.com Dec. 27, 2021

Dec. 27, 2021

Ubuntu 20.04.3 Pharo-9.0.0+build.1573 I am a noob just getting started with Pharo. After tuning some System preferences (e.g. switching to Pharo Light theme, etc.) the lessons in âLearn Pharoâ available from the âWelcomeâ window are near black and unreadable. When I click on âLearn Pharoâ the initial page is okay (black or blue type on a black background) but doing â`ProfStef go.`â messages opens the next lesson where all text has such a black background it is unreadable. Doing â`ProfStef next.`â or â`ProfStef previous.`â on subsequent pages opens a new page similarly illegible. Iâve searched through all the System prefs but canât figure out which one affects the lesson pages. Regards, Hedley

Pharo won't start on Ubuntu
by hedley.finger＠gmail.com Dec. 27, 2021

Dec. 27, 2021

Pharo 9 (amd64) Ubuntu 20.04.3 LTS (Focal Fossa) I installed Pharo 9 by following the instructions for Xubuntu 20.04 at [OpenSuse Builder](https://bityl.co/ABlH "OpenSuse Builder"). Next I checked for a starter script: `hedster:~$ which pharo` `/usr/bin/pharo` Then I executed the script â¦ `hedster:~$ pharo` â¦ which did not start the Pharo GUI but produced a pile of error messages I donât understand. Iâm sorry to inflict this on you because it is rather long. See the CLI output below.

Thanks, Stephane. I am aware of this now most comfortable possibility to gain access to the newest image. I want to prepare to be able to offer feedback when making changes while working with it; esp. reporting on glitches, and, possibly, code contributions. As of my understanding, up-to-date local repositories in sync with the image are neccessary to do that. Am I wrong?

Pharo9 GLORP + MySQL
by laszlo.szolnoki＠gmail.com Dec. 24, 2021

Dec. 24, 2021

Hi, Iâm new to the Pharo users mailing list and to Pharo in general, too. My goal is to make a CRUD web application using Seaside, Magritte, GLORP and MariaDB (MySQL-like RDBMS). I already test-drove GLORP with PostgreSQL-P3, with success. But I need MariaDB because it implements SQL:2011 (which Postgres lacks currently) thus enabling the use of system-versioned and bi-temporal tables. Currently I donât need GLORP to handle any of the SQL:2011 features as the versioning would be invisible to the web app, it is needed only for auditing purposes. I tried to make the system work be installing the MySQL driver into a fresh Pharo9 image: Metacello new repository: 'github://pharo-rdbms/Pharo-MySQL'; baseline: 'MySQL'; load Since the package 'MySQL-Glorp' didn't load, I installed it manually from github. (Sorry but I'm noob to work with baselines, Iceberg, Monticello and such.) Then loaded GLORP: Metacello new repository: 'github://pharo-rdbms/glorp'; baseline: 'Glorp'; load. Then I tried to do everything in a similar manner to how I did it with P3: login := Login new database: MySQLPlatform new; username: 'root'; password: '\*\*\*\*'; host: '<my host>'; port: '3306'; databaseName: 'test'. accessor := DatabaseAccessor forLogin: login. accessor login. accessor isLoggedIn. >>> true Yay, very nice. Then: session := GlorpBookDescriptorSystem sessionForLogin: login. \*GlorpBookDescriptorSystem is subclass of DescriptorSystem. It comes from the demo from pharobooks with an example on how to use GLORP with P3. It contains the demo class models, descriptors and table definitions. And finally: session login. >>> Instance of MySQLDriver did not understand #queryEncoding \:( Any hints appreciated.

Survey of Library Update and Breaking Changes
by Oleksandr Zaitsev Dec. 21, 2021

Dec. 21, 2021

Hi everyone, Could you please take 5-10 minutes of your time to take part in our survey? We want to understand how developers deal with API breaking changes, what problems do they have when updating to the new version, etc. https://framaforms.org/library-update-how-to-manage-dependencies-on-the-evo… If you are also developing a library, framework, or microservice (anything that has an API, multiple versions, and some users other than yourself), please answer my second survey: https://framaforms.org/library-update-how-do-you-manage-changes-in-the-api-… This survey is also quick to answer (5-10 min). And this doesn't have to be a very big library. Even if you developed a small tool that some people use, I am really interested in your answers! If you are interested in the results of those two surveys, please specify your email address (last optional question) and I will send you the summary of our study. Thank you for your help, Oleksandr

Dear all, I would like to load a complete dev image with all repositories affected for pharo 10 under development. Is there a documentation I can follow?. Where can I find pharo-spec2 pharo-newtools libgit2-pharo-bindings ? Can I acess these? Kind regards, Friedl
