#InterSystems IRIS

I have a custom Buffer class which is designed to capture written/printed statements to the device, to be able to transform the captured text to string or stream type. I have used this in ObjectScript to capture ObjectScript write statements and return a string. I would like to try to use this with a [ Language = python ] method as follows. This class will be called by a scheduled task.

When I install the numpy package on Python on my PC using:

pip install numpy

I can use it in python on my machine. If I do:

pip install --target C:\InterSystems\IRIS\mgr\python numpy

I get errors any time I try to import it in embedded python.

Hi

I'm getting an error when trying to connect to rabbitmq using the link and source code below.

Is there a solution?

https://community.intersystems.com/post/how-produce-and-consume-rabbitm…

Set setting = ##class(%External.Messaging.RabbitMQSettings).%New()

Set tClient = ##class(%External.Messaging.Client).CreateClient(setting, .tSC)

Error : 5023,"Connection cannot be established"

Thank you

Overview

The typeorm-iris project provides experimental support for integrating TypeORM with InterSystems IRIS, enabling developers to interact with IRIS using TypeORM’s well-known decorators and repository abstractions. This allows a more familiar development experience for JavaScript and TypeScript developers building Node.js applications with IRIS as the backend database.

While the project implements key integration points with TypeORM and supports basic entity operations, it’s not yet battle-tested or suitable for production environments.

It appears as though command history is not available via up/down arrow keyboard keys when using the SQL Shell. Is there anything in the works to change that?

Also, typing the colon character (:) as the first character after the prompt in Terminal Lite does odd things in 2025.1.1 ... every keystroke starting with the colon is echoed back and pressing Enter generates an error:

The red :SQL on the first line was echoed simultaneously as the :SQL in white was typed. Also, it's obvious that aliases don't work in Terminal Lite 😉

IrisTest is a light weight, powerful, user-friendly tool designed to simplify unit test report generation. It includes an interactive shell and API to facilitate communication, allowing developers to easily manage and generate reports for their test runs in various formats. Whether you're debugging or creating detailed reports for analysis, IrisTest makes the process smooth and efficient!

Reviewing my published packages, I identified a nasty bug in IRIS Native API

If you like what you see please support this in the Developer Tools 2025 contest. Voting closes at midnight EDT on Sunday 3rd.

Working in healthcare IT as a young developer, especially on InterSystems TrakCare, you quickly realize one thing: it’s not just about HL7 messages or backend integrations. A hugepart of making TrakCare work smoothly for hospitals comes down to how it’s configured, customized, and supported on the application side.

That’s where people like me come in—techno-functional developers who understand both the tech and how it impacts actual hospital workflows.

We’re Not Just Techies (or Functional Consultants)

Our role sits right in the middle. We're the ones:

Here is what I currently have:

If you’ve ever watched a true artisan—whether a potter turning mud into a masterpiece or a luthier bringing raw wood to life as a marvelous guitar—you know that magic isn’t in the materials, but in care, craft, and process. I know this firsthand: my handmade electric guitar is a daily inspiration, but I’ll admit—creating something like that is a talent I don’t have.

⏯️  AI Clinical Trial Platform

The Trial AI platform leverages InterSystems cloud services including the FHIR Transformation Service and IRIS Cloud SQL to assist with clinical trial recruitment, an expensive and prevalent problem. It does this by ingesting structured and unstructured healthcare data, then uses AI to help identify eligible patients.

This article will introduce you to the concept of virtual environments in Python, which are essential for managing dependencies and isolating project from the OS.

What is a Virtual Environment?

A virtual environment is a folder that contains :

• A specific version of Python
• At start an empty site-packages directory

Virtual environments will help you to isolate your project from the OS Python installation and from other projects.

How to use it?

To use virtual environments, you can follow these steps:

I am brand new to using AI. I downloaded some medical visit progress notes from my Patient Portal. I extracted text from PDF files. I found a YouTube video that showed how to extract metadata using an OpenAI query / prompt such as this one:

ollama-ai-iris/data/prompts/medical_progress_notes_prompt.txt at main · oliverwilms/ollama-ai-iris
 

I combined @Rodolfo Pscheidt Jr https://github.com/RodolfoPscheidtJr/ollama-ai-iris with some files from @Guillaume Rongier https://openexchange.intersystems.com/package/iris-rag-demo.

I attempted to run

Thirteen years ago, I attained dual undergraduate degrees in electrical engineering and math, then promptly started full-time at InterSystems using neither. One of my most memorable and stomach-churning academic experiences was in Stats II. On an exam, I was solving a moderately difficult confidence interval problem. I was running out of time, so (being an engineer) I wrote out the definite integral on the exam paper, punched it into my graphing calculator, wrote an arrow with “calculator” over it, then wrote the result. My professor, affectionately known as “Dean, Dean, the Failing Machine,”

Overview

The extension and source code are now available
After having some discussions at Global Summit and using a lot of package managers in my day to day development (npm,nuget,Chocolatey, etc) in addition to recently using the InterSystems Package Manager for some CICD process I'm building using Intersystems IRIS and IRIS 4 Health, I wanted an easy and integrated way to search/view/install packages related to the Intersystems tech stack.

SQL injection remains one of the most critical vulnerabilities in database-driven applications, allowing attackers to manipulate queries and potentially access or compromise sensitive data. In InterSystems IRIS, developers have access to both Dynamic SQL and Embedded SQL, each with distinct characteristics. Understanding how to use them securely is essential for preventing SQL injection.

The Problem: Dynamic SQL and SQL Injection

Overview I'm excited to announce the release of testcontainers-iris-node, a Node.js library that makes it easy to spin up temporary InterSystems IRIS containers for integration and E2E testing. This project is a natural addition to the existing family of Testcontainers adapters for IRIS, including testcontainers-iris-python and testcontainers-iris-java.

Why testcontainers-iris-node? As a Node.js developer working with InterSystems IRIS, I often faced challenges when setting up test environments that mimic production. testcontainers-iris-node solves this by leveraging the testcontainers-node framework to create isolated IRIS environments on-demand.

This is particularly valuable for:

• Integration testing with IRIS databases
• Testing data pipelines or microservices
• Automating test environments in CI pipelines

Features

• Launches IRIS in Docker containers using Testcontainers
• Supports custom Docker images and configuration
• Wait strategies to ensure IRIS is ready before tests begin
• Clean teardown between test runs

Why Randomization is Key When Splitting Data for Machine Learning

Post:
Essentially, Machine Learning is about learning from data. Having "good" data leads to better models, and more importantly, the quality of the information being used plays a crucial role in improving prediction accuracy.

One critical step in the process is how we separate our data into training and validation sets. If this isn’t done properly, we risk introducing bias, overfitting, or unrealistic performance expectations for the model.

In this article, we’ll explore:

Well... It's time for testing. We know that often, it's already over. So, what now? Can I improve the quality of my development?

The answer is: YES. Yes, you can. The Toolqa tool aims to do just that. It's a facilitator. What's its goal?

To ensure that APIs meet pre-established business requirements, while also protecting against <sarcasm>  future failed attempts </sarcasm>  to destroy your application, website, app, or anything else that uses your API.

Now you might be wondering, how does this happen? Where's the magic?

Hi everybody,

A customer would like to connect an IRIS database to Metabase BI.  But Metabase does not have a connector that supports the IRIS database.

Metabase only supports these databases:

- Amazon Athena
- BigQuery (Google Cloud Platform)
- Druid
- MongoDB (recommend version 4.2 or higher)
- MySQL (recommend version 8.0.33 or higher, as well as MariaDB version 10.4 or higher)
- Oracle
- PostgreSQL
- Presto
- Redshift (Amazon Web Services)
- Snowflake
- SparkSQL
- SQL Server
- SQLite
- Vertica

And a few others. 

Sometimes your client may request documentation of your BI or interoperability project in a formal document. In this case, MS Word is a good alternative, as it has an advanced editor that allows you to generate professional documentation. Now it's possible!
The iris4word app has this functionality!

Hello everyone,

I would like to ask whether it is possible to run InterSystems API manager (IAM) on OpenShift. Is there some documentation describing how to do it? I was searching the forum as well as the internet and I have not found much unfortunately.

Any hints would be highly appreciated.

Best regards

Word documents are widely used in the market. Users frequently create contracts, memos, resumes, reports, analyses, and other documents that may require data from or captured by InterSystems IRIS. However, IRIS does not have an API, SDK, library, or adapter for this. This limitation no longer exists. 

The new Open Exchange library iris4word (https://openexchange.intersystems.com/package/iris4word) delivers an ObjectScript SDK where the developer passes any %DynamicObject as a parameter, a Word file template and then receives a ready document, with the structure and formatting defined in its template.

Let's start with a simple motivating question: over the past 14 days, what are my most common errors in the Application Error Log?

Answering this through the management portal or terminal is an annoying manual process - we should just be able to use SQL. Fortunately, there are a few class queries to help with this in the SYS.ApplicationError class in the %SYS namespace. You can answer the question for a single date with something like:

select"Error message",count(*)
from SYS.ApplicationError_ErrorList('CCR','12/16/2024')
groupby"Error message"orderby2desc

If you are investigating complex structured Globals this can become
a rather boring typing exercise. Different from Global Explorer in
System Management Portal Global-Inspector allows a kind of drill-down
to dig deeper and deeper by subscript levels.
You also have the option to see the stored content or to show only
the subscript structures.
Globals storing SQL Tables are probably not so thrilling, but in SYSTEM
space you find real trees with completely different branches and twigs.

Global-Inspector can run in browser or from terminal command line.

Imagine you’re walking down the street on a nice summer’s day, and someone walks up to you and says “Hey, you work at InterSystems, right? I’ve been hearing more and more about InterSystems IRIS lately. I know IRIS has its own programing language called ObjectBook? or InstaScript? OK, I admit it, I know it’s called ObjectScript! I know IRIS also supports Python. I’m a Python developer, so that sounds great to me. But I’m also interested in ObjectScript. For example, Python and other languages support collections. Does ObjectScript support collections?”

You’d answer “Of course!”

And then your new friend might get excited and start firing off more questions:

• How many kinds of collections does ObjectScript support?
• Can ObjectScript use Python collections?
• Can Python use ObjectScript collections?
• Which collection is best?

How would you answer? Well, you don’t have to worry about answering. All you’d have to do is send your new friend the URL of this long page.

The new version of InterSystems Testing Manager which I released last week brings @Timothy Leavitt's cool 
Test Coverage Tool to VS Code, and is my entry for the 2025 Developer Tools contest.

Here's a teaser screenshot showing how the unit tests of the IPM project don't yet cover a feature that apparently allows an IPM repository to override its sort order.

Now that we have a good understanding of Python and its features, let's explore how we can leverage Python within IRIS.
