Re: [Pharo-users] Updating singletons

Konrad, This looks like a case where you are using a metadata-less repository ... if so you, should add the following method to your baseline class: projectClass Smalltalk at: #'MetacelloCypressBaselineProject' ifPresent: [ :cl | ^ cl ]. ^ super projectClass This mod will cause packages to be unconditionally loaded ... Monticello does a definition comparison on package load so only changed definitions are loaded into the image ... Hope this helps, Dale On 1/4/19 5:12 AM, Konrad Hinsen via Pharo-users wrote: > Subject: > Re: [Pharo-users] Updating singletons > From: > Konrad Hinsen <konrad.hinsen(a)fastmail.net> > Date: > 1/4/19, 5:12 AM > > To: > pharo-users(a)lists.pharo.org > > > H Cyril, > >> Fetching, loading and post loads should leave a trace during the >> execution in the Transcript. > Thanks, that helps to confirm that my postload is never executed when I > update a package + baseline in an image that already had an earlier > version loaded.

Roassal Explorer
by Alan Capewell Jan. 7, 2019

Jan. 7, 2019

When I use the Explorer view in Roassal, clicking on the root node causes the view to open a new panel with an inspector on the element. When I expand out the tree and click on a child element the inspector does not refresh. Is there a simple way to enable that behaviour? Kind regards Alan

[ANN] P3 version 1.1
by Sven Van Caekenberghe Jan. 6, 2019

Jan. 6, 2019

Hi, I created a new release of P3, the modern, lean and mean PostgreSQL client for Pharo. https://github.com/svenvc/P3 Version 1.1 contains the following changes: - added support for Postgres Extended Query protocol (P3PreparedStatement) (thx Jan @jvdsandt) - added support for reading array type values (currently INTEGER[] FLOAT[] BOOLEAN[] TEXT[] VARCHAR[]) - added P3-Tests package and moved all tests there - more comments - more unit tests https://github.com/svenvc/P3/releases/tag/v1.1 Especially Jan's contribution adds a lot of functionality: the ability to work with prepared statements. Here is an example doing a batch insert of 100 records (which is more efficient). | client statement | client := P3Client url: 'psql://sven@localhost'. client execute: 'DROP TABLE IF EXISTS table1'. client execute: 'CREATE TABLE table1 (id SERIAL PRIMARY KEY, created_at TIMESTAMP DEFAULT NOW(), name TEXT)'. statement := client prepare: 'INSERT INTO table1 (name) VALUES ($1)'. statement executeBatch: ((1 to: 100) collect: [ :index | Array with: ('Text #', index printString) ]). client query: 'SELECT * FROM table1'. client execute: 'DROP TABLE table1'. statement close. client close. Season's Greetings to you all. Sven -- Sven Van Caekenberghe Proudly supporting Pharo http://pharo.org http://association.pharo.org http://consortium.pharo.org

Re: [Pharo-users] Discord Server invite is now private because of spammer
by Dimitris Chloupis Jan. 6, 2019

Jan. 6, 2019

After discussing it with Stef and Esteban and of course Ben . we reached the conclusion to have only a few days keeping the invite link private. After that it will become public again to make it easy for people to join without any hassle. If the problem reappears we can discuss whether further action is needed, in the meantime I will try to ban members generated by the bot. I wont be deleting it without consulting you first. Admins please refrain from creating additional invite links, one should be enough and will make everyone life a lot easier. The new link has no expiration date. Making the invite link public means that the links to the link , like the one on the website , will have to be updated to the new one. I do not have access to those places so people that do will have to update it. I will make the link public in this thread in a few days. in case the people that are responsible for sharing the link are not admins in Discord and they cannot access it. Again I apologize for the inconvenience but it was a necessary action to minimize the problem. I am at your disposal for any further clarification and assistance.

Change the name of the programer in the image
by Alidra Abdelghani Jan. 5, 2019

Jan. 5, 2019

Hi, In a fresh Pharo image, when you edit your first method the system asks you for your name. Sometimes, I share some images with my students so I wonder if it is possible for them to enter their name instead of mine when they edit their own code? Thanks in advance Abdelghani

Discord Server invite is now private because of spammer
by Dimitris Chloupis Jan. 5, 2019

Jan. 5, 2019

Hello people , as you may or may not be aware we have a spammer that posts links to sexual content sites. This is of course an unacceptable situation so I had to delete all existing invite links. This means that from now on I will not allow members to create their own invite links and I will also not allow more than one link to be active at a time so I know which link is compromised. The invite link will no longer be public but shared privately only by Admins to people who are already active here and it will be shared only through personal emails and messages. I have also raised the level of automatic moderation , from now on new members wont be able to post in our server unless they have a verified email with Discord. Also all messages are automatically scanned by Discord from now on for improper behavior. I am sorry for this inconvenience but its all part of having a very active community, it was just a matter of time till we attracted the attention of spammers. This does not affect our almost 1000 existing members on Discord server so if you already a member you have nothing to worry about. This affects only new people who like to join. If you are new and you like to join I will send you an invite link ONLY if you are active in this mailing list and after you are ask for one. You can use this thread by providing your Discord ID (you get this when you register with discord) and I will send you a personal message in Discord with an invite link. By active I mean that you have substantial participation in this mailing list which means at least 3 posts. If you are a member or admin and post the link publicly , its not a problem, but please be aware that if the link is compromised then I will delete it and create new making new members unable to join with the old one. So use the link wisely. You can also contact one of the other admins , if you know who they are and they know who you are. If you dont then use this thread and be patient. Once you join there are no restrictions or anything else that will make your life not easy. Happy Pharoing ;)

Managing Code - Creating a Library/Package from scratch?
by Todd Blanchard Jan. 5, 2019

Jan. 5, 2019

The bit I always struggle with on various Smalltalk environments is the right way to manage code. It keeps changing. Which is fine. But I've been away for a bit and I'm lost now. I want to create a new package that can be loadable and lives in a git repo. I guess Metacello is part of that. And Iceberg. And...what else? I want to build a library but am no longer clear on what a library (or package I guess) definition is built from. Thanks.
