New and Upcoming Embedded Git features

It's been a while since I've posted about Embedded Git on the Developer Community, and I'd like to provide an update on the massive amount of work we've done this year and where we're going next.

Context

If you're building solutions on IRIS and want to use Git, that's great! Just use VSCode with a local git repo and push your changes out to the server - it's that easy.

But what if:

Today, we take a moment to shine the spotlight on one of the true pillars of the InterSystems Developer Community, @Alberto Fuentes. His commitment, expertise, and enthusiasm have left an indelible mark on the Developer Community, and we couldn’t be more grateful. Alberto has been a part of the InterSystems ecosystem for over 15 years, starting his journey with InterSystems technology back in 2008. Since then, he has worn many hats, from integrating Ensemble at his previous job to officially joining InterSystems in 2011 and now holding the position of Sales Engineer. Over the years, he’s witnessed—and contributed to—some of the most significant milestones in the company’s history.

🤩 Let’s dive into his remarkable journey!

Hi colleagues!

Yet another time I figured that there is no super-simple way to display error from %Status variable, but I need it relatively often in a terminal.

Yes, I know about $$$ Macro, but they are not superhelpful in a terminal.

My usual behavior is to try to remember by heart or copy from somewhere the formula:

USER>w $System.Status.DisplayError(st)

Hi Developers,

We’ve got great news — the Developer Community has a new, smart, and proactive helper:

🤖 Developer Community AI Bot a.k.a. @DC AI Bot 🤖

Powered by the same IRIS Vector Search technology as the DC AI assistant, our new @DC AI Bot takes it a step further:

👉 it automatically scans every newly posted question — and, if it finds a relevant answer, leaves a reply right in the comments.

Here’s a special thread where you can tell a bit about yourself — because connecting and learning more about each other is what makes this community great 💬✨

We had a similar discussion on our old Global Masters platform — you might remember! We’re excited to bring that networking opportunity back to the community.

ORU to MDM with large HL7 v2 messages.

I was working on a DTL but kept getting ERROR #5002... MAXSTRING errors. The problem was that most of the DTL GUI action steps only support the string data type when working with the segments. A %String has a limit of 3,641,144 characters and my OBX5.1 was 5,242,952 characters long as the example provided. Of course PACS admin stated ultra high quality up to and including 4K resolution files were needed, so we could not get the vendor to compress or reformat these files to compressed jpg or something similar.

When you deploy code from a repo, class (file) deletion might not be reflected by your CICD system.
Here's a simple one-liner to automatically delete all classes in a specified package that have not been imported. It can be easily adjusted for a variety of adjunct tasks:

set packages = "USER.*,MyCustomPackage.*"
set dir = "C:\InterSystems\src\"
set sc = $SYSTEM.OBJ.LoadDir(dir,"ck", .err, 1, .loaded)
set sc = $SYSTEM.OBJ.Delete(packages _ ",'" _ $LTS($LI($LFS(loaded_",",".cls,"), 1, *-1), ",'"),, .err2)

The first command compiles classes and also returns a list of loaded classes. The second command deletes all classes from specified packages, except for the classes loaded just before that.

I’m pleased to announce the release of tree-sitter-objectscript, a new open-source tree-sitter grammar that brings first-class ObjectScript support to modern editors. If you caught the preview at READY ’25, you’ll be glad to know it’s now up on Github:

I have an IRIS installation that is using 8-bit charset encoding (set to deu8 / Latin 1). I would like to convert everything (database and system) to Unicode

Charset encoding is something asked during installation, is it possible to change this on the fly ? The installer clearly say that Unicode systems cannot be converted. What about 8 bit ?

Same for database : is there possible conversion ?

My current plan is the following :

I have started working on utilizing Epic on FHIR about a month ago.

Creating a Public Private Key Pair

mkdir /home/ec2-user/path_to_key
openssl genrsa -out ./path_to_key/privatekey.pem 2048

For backend apps, you can export the public key to a base64 encoded X.509 certificate named publickey509.pem using this command...

Motivation

I didn't know about ObjectScript until I started my new job. Objectscript isn't actually a young programming language. Compared to C++, Java and Python, the community isn't as active, but we're keen to make this place more vibrant, aren't we?

I've noticed that some of my colleagues are finding it tricky to get their heads around the class relationships in these huge projects. There aren't any easy-to-use modern class diagram tool for ObjectScript.

Hi,

We’re launching an Early Access Program for an upcoming Table Partitioning feature that will help IRIS customers manage very large tables, and distribute row data and associated indices across databases and storage tiers. Table Partitioning cuts deep into the core of IRIS relational data management, so we want to make sure we get things right through working with a few engaged customers who can provide feedback on the initial deliverables, and fine-tune as needed.
