Quickly Open Things in 4D Development Environment and Sync Code Between Projects – Cannon Smith
Project mode in 4D opens some interesting development tool possibilities that we didn’t have before, especially now with the new FORM EDIT command added in v18 R5. In this meeting, we’ll explore two such tools that have been made available publicly on GitHub… DevQuickOpen and DevSync.

Building your own Classes in 4D: Examples and sample code – Tim Nevels
4D v18 R3 introduced another new feature to the 4D programming language which will be sure to transform application architectures for years to come: Classes. In short, this is a pretty big deal.
But Object-oriented programming (OOP) concepts may be unfamiliar to some of us, and the functionality in 4D is certainly new. So let’s all start exploring and digging into the new concepts together!

A Modern Component for Reading Delimited Text Files – Dani Beaubien
The applications we write sometimes need to import and process information from tab-delimited/csv files. The code needed to open, validate and prepare the file for processing is quite similar in each case is usually duplicated with each file importer. It gets even more complicated when handling the positions that that columns might appear in.

Modularizing Collection and Entity Selection List Boxes – Kirk Brooks, Guy Algot
For database applications, what could be more important than how to display data in a user interface? Is your application still using output list forms? Maybe Current Selection list boxes? Then it is probably time for an update!
Check out the session I put together for the 4D Summit 2020! It was a lot of fun to put together, and the potential is easy to see once you get to the macros. What a bummer that I could not share it in person in Chicago and in Paris as planned due to the pandemic, but please enjoy the recording I made at home…
The demo code is available here… https://github.com/4dmethod/Jira
If there is interest, I might also make a Redmine module with the same features. Let me know with some upvotes or by email if you could use something like that.
Stay well!

How to implement a Worker queue monitor using Storage – Tim Nevels
Tim Nevels, President of Innovative Solutions, has a project that uploads many thousands of documents to Dropbox. To maximize bandwidth usage and reduce the upload time, Tim coded the application to use multiple thread-safe worker processes. However without a way to monitor the queue of jobs waiting in each process, he saw that he had no idea how big the queue of each worker was getting and thus had no idea of how many documents were still waiting to be uploaded.

Art Institute of Chicago API, Nikhil Trivedi & Illya Moskvin
In the year leading up to the Art Institute of Chicago’s 2018 website redesign, a team of internal developers created a central repository for all of our public data—collections as well as digital catalogs, in-gallery experiences, events, shop products and more. Utilizing a microservices architecture, our data hub fuels a rich experience on our website, mobile apps, and more, and eases system integration by providing a single, searchable, unified API.

AJ Suite of Components, Gabriel Inzirillo
AJAR SA is the Swiss 4D Distributor. It has more than 25 years experience in distributing 4D Solutions to the Swiss and Liechtenstein markets. AJAR’s expertise in 4D is far more than simply distributing the 4D Solution. AJAR SA offers many services such as first level support, consulting, training, and audits. All of that combined with a tight relation with 4D SAS gives their partners the best service possible.
Since a long time ago, AJAR SA have proposed some components to the 4D developers (ToolTip, Regex, etc.), but those components were never harmonized and some were even never released. In that matter, AJAR is now bringing forth some tools that can help 4D developers to build applications with some nice UI features as well as some well-designed tools to help solve some daily business issues.
