[ANN] Soil release v1
by Norbert Hartl April 24, 2024

April 24, 2024

...we said at last ESUG that there will be a release soonish but as usual it doesn't go that fast. But now we are very happy to announce that Soil has a first public release v1. So what is soil? Soil is an object oriented database in pharo <http://pharo.org/>. It is transaction based having ACID transactions. It has binary search capabilities with SkipList and BTree+ indexes. It aims to be a simple yet powerful database making it easy to develop with, easy to debug with, easy to inspect, ... More details at https://github.com/ApptiveGrid/Soil This release is still considered early stage because although in ApptiveGrid there are over 4000 instances of it and there are other users there isn't a wider range of use cases, yet. So it is not fully battle tested. This just as reminder when you start compaining I need somewhere to point my finger to and say "I told you!" ;) there are few things missing that you might expect like garbage collection, etc. So but it is definetely usable and awaiting the brave ones of you to try. Hopy you enjoy it! Norbert & Marcus

UKSTUG meeting - Tudor GÃ®rba: What exactly is Glamorous Toolkit? - 24 April 2024
by UK Smalltalk April 22, 2024

April 22, 2024

To some people Glamorous Toolkit is a Pharo environment. To others itâs a knowledge management system. Others might see a code analysis platform, a data visualization or an API browsing tool. Yet others see the graphical stack with its interactive editors. Glamorous Toolkit is all of these. But itâs really also none of these. These are merely examples of the many forms the environment can be molded to. And there can be many more. Glamorous Toolkit is primarily an environment that makes it possible to create many experiences seamlessly and contextually. This then leads to a new way of programming that we call Moldable Development. Tudor GÃ®rba is a software environmentalist and the CEO of feenk.com ( http://feenk.com/ ) where he works with an amazing team to make the inside of systems explainable. Much of the work is embodied in Glamorous Toolkit ( gtoolkit.com) a novel environment that enables moldable development. 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/300575234/ ) to receive the meeting details. Donât forget to bring your laptop and drinks!

How to log pharo output to stdio safely?
by Tim Mackinnon April 20, 2024

April 20, 2024

Hi - I've been messing around with deploying a hobby pharo app to the web.. which has become a lot simpler over the years, although the tech keeps changing and you have to relearn things. Anyway, I have my image in one of the wonderful BA Docker containers, and it runs well - and the host I'm using will show the logs for you, so you can figure out what is going on... well that is if your logs come out properly (and of course, if it gets really hairy then you can get a VNC session onto the image and figure stuff out) So logs are handy, and pharo these days has a nice headless mode that redirects the Transcript to stdout - and there are also a few decent logging frameworks as well. But as most things go to the Transcript, and that goes to stdout - it should be good. HOWEVER - flushing is the killer, as if things happen and the last thing goes wrong, but the output isn't flushed, then you aren't going to see it. So my question is how to properly flush? And I'm sure I've read something about this before, but I can't find it. >From memory, you often need to have a Transcript cr. to flush your last line. BUT, most things in the image seem to use "self crTrace:" these days, which is a cr to ensure the previous msg is separated from what you want to write, and then you write your line out. However, as there is now cr - you might not see it. So I tried changing my stuff to use "self traceCr:" (which is in the image), and that still didn't seem to work - the last failing line wasn't being output. Worse still, its confusing, as many things in the image are using crTrace: and so you get intermingled messages, which are hard to decipher. So I tried: Transcript cr; show: msg; flush But that didn't seem to work (which I don't understand) Eventually I did: Transcript show: msg; cr; flush And this seems to ensure things do reliably get outputted - but I'm wondering if anyone can shed light on this areas? Ideally I want to use: Transcript cr'; show: msg; flush As this plays much better with everything that is in the image - but is there some way to do this? And indeed, will log tools the Bettersatack or papertail play ball with output like this (as I guess they operate on complete lines to interpret log levels etc), Anyway - I'm curious if anyone else has done work in this area to shed light? Thanks, Tim As an aside - for deployment - several years ago I came across dockerize.io - which lets you upload a Docker image to a host, and it will run it for you. Sadly that service didn't survive... but there are quite a few like it now, and so I'm trying Render.com - which is similar, but the twist is you need to store a Docker image in a registry somewhere (I use gitlab from my CI pipeline), and then it will retrieve it and run it for you (for either free in 40 minute chunks, or for $7/m - which is pretty good, and possibly bit simpler than Digital Ocean). Its pretty cool, and maybe I will write up about it sometime

remove breakpoint ?
by Haroldo Stenger April 14, 2024

April 14, 2024

hi nice pharo people I'm doing my very initial attempts in Pharo. Having read something here and there. Now I've put myself to subclass BlElement in order to add a method of myself to this subclass. The subclass got named 'Circulo'. Then I had a hard time trying to create a protocol to 'host' it, but finally it got created as protocol 'a'. Initially it got created in the third pane in the browser, below without any apparent 'breakpoint hierarchy'. However, as soon as I wrote the method and got to save/accept it, something strange happened, namely, 'brakepoint' protocol was created out of nothing , and my 'a' protocol was put under it. The method itself in the fourth pane, has a red ! sign. If I right click on the method, and try to remove the breakpoint, it does nothing. What happens this and how can I have a normal situation , since I did not put breakpoints ? Thanks for your kind help
