Argus Development Environment Shell & Tools for 4D – Jody Bevan
Let Jody Bevan take you on a tour of the Argus Development Environment (ADE). Jody has been a big name in 4D development since his days with JonokeMed, what used to be one of the widest used medical applications of its type in Canada. He has rolled that momentum and experience forward into his latest project, Argus ADE. Continue reading

Building developer.4d.com, a Markdown-based Documentation Site – Arnaud Schmitt
Some of us live by the mantra “When all else fails, read the manual.” However I think that applies better to Ikea than 4D application development! We all rely heavily on 4D documentation and are often even obliged to create documentation for our own applications (see… developers favorite task).
This meeting will offer us all a rare peek behind the scenes of how 4D documentation is maintained and how the approach is changing to keep pace with the evolving platform.

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.
