UK Smalltalk User Group meeting - Wednesday March 31st

by Giovanni Corriga

The next meeting of the UK Smalltalk User Group will be on Wednesday, March 31st. In this meeting, Juan Vuletich will present a Vector Graphic implementation in Cuis Smalltalk. Graphics for interactive software have traditionally been constrained for performance reasons. The consequence is that most software has serious trouble adapting to higher resolution screens, requires platform specific widget kits, provides limited functionality, and has sub optimal visual quality. But improvements in computing power over the last couple of decades enable a brighter future: Cuis Smalltalk provides a VectorGraphics based implementation of the Morphic UI framework that addresses all these issues. Juan is a long standing member of the Open Source Smalltalk community. He started Cuis Smalltalk ( https://www.cuis-smalltalk.org/ ) 12 years ago and has led it ever since. He has been contributing kernel code to Squeak and the Squeak VM for over 20 years. He holds an Ms.Sc. in Computer Science from the University of Buenos Aires. 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/cbklbryccfbgc/ ) to receive the meeting details. Donât forget to bring your laptop and drinks!

david did you succeed to clone or checkout a github repo from this machine and without pharo at all? Because Pharo is just using libgit.

I am not sure if it solves your problem but you could set to load via https with: Iceberg remoteTypeSelector: #httpsUrl before loading with metacello Am Mo., 22.

David I think that we will release a new Windows VM soon. We are chasing a problem related to some failures on Windows. Now I cannot give you a fixed date. > On 22 Mar 2021, at 16:36, David Pennington <david(a)totallyobjects.com> wrote: > > Hi everyone. > > I have been developing a new web site using Seaside on my M1 MacBookAir and I have had no issues. > > To deploy it, I have to install Pharo on either a Windows 10 or a Windows Server 2012 server.

Problem installing Seaside on Windows

by David Pennington

Hi everyone. I have been developing a new web site using Seaside on my M1 MacBookAir and I have had no issues. To deploy it, I have to install Pharo on either a Windows 10 or a Windows Server 2012 server. Pharo has installed on both without any issues. However, I am having problems installing Seaside. I have Pharo 8.0 installed on both (64 bit version). If I try and install from the Catalog, I get the following error in the Transcript. IceGenericError: Failed to stat file 'C:/Users/david/Documents/Pharo/images/Pharo 8.0 - 64bit (stable)/pharo-local. If I try using Monticello, I get the following: Metacello new baseline:'Seaside3'; repository: 'github://SeasideSt/Seaside:master/repository'; load I got an error while cloning: There was an authentication error while trying to execute the operation: . This happens usually because you didn't provide a valid set of credentials. You may fix this problem in different ways: 1. adding your keys to ssh-agent, executing ssh-add ~/.ssh/id_rsa in your command line. 2. adding your keys in settings (open settings browser search for "Use custom SSH keys" and add your public and private keys). 3. using HTTPS instead SSH (Just use an url in the form HTTPS://etc.git) I will try to clone the HTTPS variant. Can you help please? David Totally Objects

Connecting to a MongoDB Atlas Cluster

by Sanjay Minni

Hi can anyone pls help me with an example of connecting to a MongoDB Atlas cluster (their cloud service). My Atlas cluster replica set is at the urls yyyy-shard-00-00.xxxxx.mongodb.net:27017 yyyy-shard-00-01.xxxxx.mongodb.net:27017 yyyy-shard-00-02.xxxxx.mongodb.net:27017 The MongoDB Atlas website specifies the application connectstring as 'mongodb+srv://<username>:<password>@yyyy.xxxxx.mongodb.net/<mydefaultdatabase>?retryWrites=true&w=majority" I saw the doc / example on pharo-nosql/mongotalk but could not figure out in MongoClient - 1. how to get embed the username:password in the connectstring which i feel would be needed, 2. how to specify the default database 3. is it required to specify all three members while Mongo suggests a single part connect string which probably must be covering the cluster thanks ----- cheers, Sanjay -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Re: [ANN] Develop in Pharo 9, run on Javascript

by Noury Bouraqadi

In PharoJS, we are able to provide a placeholder for a class upon transpilation. So, if we know which class/method to replace, we have a tool. But, we don't have a list of stuff requiring specific support/transpilation in PharoJS. And I didn't dig deep enough to list all missing stuff. Yes, I'm lazy, I use TDD :-) There's however few things we know are not support (yet) such thisContext is one of them (No idea how to handle it). Process and related classes is another another bucket, though we have a plan for it. Networking faces the same issues as graphics. We need to replace libraries. Note that, as for graphics we can use JS libraries, but we loose the benefit of pharo compatibility. Noury
