STON reader problem
by David Pennington May 27, 2021

May 27, 2021

OK, so I have installed Pharo 9.0 with the M1 VM and everything is nice and quick. I am porting my code across and I have a problem that involves STON Reader. I use this to convert my objects for storage in my text based database. I canât run my code because STON Reader fails when reading in one of the objects. The contents are as follows: "{#entryName:'PAYPAL *COSYFEET',#entryDate:Date['2021-01-25Z'],#transactionID:'202101250001',#entryAmount:-5041216832887849/140737488355328s8,#entryCategory:nil,#entryDescription:'35314369001 GB , 5959 22JAN21',#match:'Nâ}â The errors is this: Character 122 is at the conjunction of the 4 and 9 in the ewntryAmount: 5041216832887849/140737488355328s8, Any help on this would be great. I have a few thousand entries to fix if there is a problem with the file (although my code works fine with this file under 8.0) David Pennington

Hi there. I am currently using v8.0 on a new M1 MacBookAir. When I save the image I keep getting a message telling me that my VM is too old and to download a new one. I have looked in my Pharo Launcher but there is no new one there. What do I do please? David

Announcements on Traits methods injection ?
by LABORDE Pierre May 25, 2021

May 25, 2021

Hello all ! I'm looking for Announcements related to Traits which are triggered when classes methods from a uses Trait are injected into a Classe (of course using this Trait). I haven't find equivalent to that, there is Announcement when classes methods are edited into a Trait but not into a Traits user. For the moment I'm using a custom pragma in my Trait class methods to have the information about the classe method modification but when the pragma is triggered from the Trait, Trait users aren't not yet updated (methods are not yet injected or linked and not available to use). After when users are updated (with adding the classes methods from the Trait) the pragma is not triggered. Thanks for your help ! Cheers, Pierre

Creating tests for the TinyBlog tutorial
by Michael Burns May 24, 2021

May 24, 2021

In TinyBlogEn-gitc55a88d.pdf on page 11 (2.7 Post Queries): TestCase subclass: #TBPostTest instanceVariableNames: '' classVariableNames: '' package: 'TinyBlog-Tests' Every time I save this new class, it ends up in the TinyBlog package, not TinyBlog-Tests. I see that many other packages have *-Tests packages where their tests live. It seems to test OK so itâs not a stopper for me, but I get an error: âTest class not in a package with name ending with â-Testsâ" Iâd like to understand. Iâm running: Pharo8.0.0 build: 1124, commit: 0932da8 On MacOS 11.3.1. M1 MbPro

The next meeting of the UK Smalltalk User Group will be on Wednesday, May 26th. Caffeine ( https://caffeine.js.org ) is a livecoded integration of the SqueakJS Smalltalkvirtual machine with the Web platform and its many frameworks. Craig Latta will show the current state of Caffeine development through live manipulation and combination of those frameworks. The primary vehicle is a Caffeine app called Worldly, combining the A-Frame VR framework, screen-sharing, and the Chrome Debugging Protocol into an immersive virtual-reality workspace. Craig Latta ( https://blackpagedigital.com ) is a livecoding composer from California. He studied music at Berkeley, where he learned Smalltalk as an improvisation practice. He has worked as a research computer scientist at Atari Games, IBM's Watson lab, and Lam Research. In 2016 he began combining Smalltalk technologies with the Web platform, with an emphasis on spatial computing. He is currently exploring spatial audio for immersive workspaces. Given the current COVID-19 restrictions, this will be an online meeting from home. If you'd like to join us, please sign up in advance on the meeting's Meetup page ( https://www.meetup.com/UKSTUG/events/cbklbrycchbjc/ ) to receive the meeting details.

Re: P3 connection error

(CC-ing the list) Hmm, that should just work. Are there any special characters in the username, password or host (non-ascii, URL unsafe characters) ? You could try the explicit init form P3Client new host: 'host'; user: 'user'; password: 'password'; database: 'database'; yourself. > On 18 May 2021, at 19:47, Bernhard Pieber <bernhard(a)pieber.com> wrote: > > Hi Sven, > > Thank you for the fast response. > > Yes, I can connect using the psql client using this command line: > C:\PostgreSQL\12\bin\psql.exe -h host -U user -d database -p 5432 > > I have to enter the password in the command prompt. > > The driver URL in SQuirreL is: > jdbc:postgresql://host:5432/database > > User name and password are separate text fields. > > pgAdmin also works, by the way. > > In P3 I use the long form: > P3Client new url: 'psql://user:password@host:5432/database'. > > Cheers, > Bernhard > >> Am 18.05.2021 um 19:16 schrieb Sven Van Caekenberghe <sven(a)stfx.eu>: >> >> >> Hi Bernard, >> >>> On 18 May 2021, at 18:40, Bernhard Pieber <bernhard(a)pieber.com> wrote: >>> >>> Hi, >>> >>> I have a PostgreSQL database on a remote host which I want to access using P3. I do have a username and a password and can connect via SQuirreL and DBeaver. Both use a JDBC driver. However, when I try to access it via Pharo and P3 I get the infamous "no pg_hba.conf entry for host <my IP address>â error. The thing is that I cannot change the pg_hba.conf file as the server does not belong to me. I wonder why the JDBC driver does not run into this problem when connecting from my IP address?
