#VSCode

SQLTools is a Visual Studio Code (VS Code) Extension with over 3.5 million downloads that provides connections to many of the most used databases, including InterSystems IRIS, using drivers. 
For developers new to VS Code, or those already familiar with it but are looking to streamline their connections to InterSystems IRIS, this tutorial will take you through installing the SQLTools extensions and the InterSystems IRIS drive. It then guides you on how to establish a connection to your instance of InterSystems IRIS and run a query.

Visual Studio Code releases new updates every month with new features and bug fixes, and the July 2025 release is now available.

When I open a class in VS Code and I want to save it I'm getting the following error : Non-JSON response to /api/atelier/v7/DEV/doc/API.Mollie.Execute.cls?ignoreConflict=0 request. Is the web server suppressing detailed errors?

Also I always get a popup when I open VS Code "The extension wants to sign in using InterSystems Server Credentials."

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

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.

Yet, in the digital world, I often see people hoping for “magic” from generative AI by typing vague, context-free prompts like “build an app.” The results are usually frustratingly shallow—no artistry, no finesse.

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.

Hi, 
I have a code that copy a method to another class for analysis purpose.

I also want this method to appear first in the source code to easily use it in VSCode with the classmethod debug button and not search it in the numerous method of the modified class.
Is there a way to do such a thing?
I tried the placeAfter keyword but I can't find a way to make it really work as I want. Is their other ways to control the order of methods?

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.

Users of the %UnitTest framework can now get test coverage information inside VS Code by combining the latest release (v2.0.0) of the InterSystems Testing Manager extension with @Timothy Leavitt's impressive Test Coverage Tool.

Above you can see the Test Coverage pane, which I have moved to the secondary sidebar on the right so it can more easily be explored in conjunction with the Test Explorer on the left.

Notice how the most recent test run (of all Test Coverage Tool's own unit tests) covered the BitValue method of TestCoverage.Procedures but not the BitCount method (nor 6 other methods).

InterSystems is pleased to announce that version 3.0.5 of the VS Code - ObjectScript extension has been released. This release includes many bug fixes, as well as changes to the telemetry data we collect. Collecting more product usage data helps InterSystems identify and prioritize fixes and enhancements that will have the most positive impact for you, our users. Personally identifiable information (PII) will never be collected, and telemetry can be disabled using the telemetry.telemetryLevel setting. The full list of data points that are collected can be found here

Hello my friends,

I have a problem with logi report, 

in my store procedure,  I create code like this?

$ListToString(%DLIST(DISTINCT (ARCIM_Desc)),'<br/>') as "ARCIM_Desc", -> this is the problem

$ListToString(%DLIST(DISTINCT (MRDIA_ICDCode_DR)),'<br/>') as "MRDIA_ICDCode_DR", -> it's works fine

as you see there's a <br/> in the display of the report

I have no idea about this, maybe someone can help me fix this problem ?

Thank You

Best Regards,

Steven Henry

Hello everyone,

I’m using VS Code with the InterSystems ObjectScript extension and I want to keep my local folder (client-side) as the “source of truth” while still using the built-in Server Source Control features (diff, stage, commit, etc.) against my IRIS/Ensemble instance.

So far:

• I have a local Git repository with my .cls and .mac files.
• I’ve configured "objectscript.serverSourceControl.respectEditableStatus": true and "objectscript.serverSourceControl.disableOtherActionTriggers": false in my .vscode/settings.json.

Are you using Jupyter Notebooks with IRIS? Are you using the vscode-iris-jupyter-server VS Code extension for your notebooking? If so, please let me know either via direct message or with a comment on this post. I'd like to hear more about how our customers are working with tool specifically, and with data science more generally.

Thanks!

I currently have an issue with a failed connection in VSCode and need some help.

It doesn't work when using ports 80, 1972, and 7038.

We have classes in a Production environment that are causing us some issues - example attached.

When we export them from the production environment the XML contains a snippet like the following:

<UDLText name="T">
<Content><![CDATA[
//Property any As list Of %XML.String(XMLNAME = "any", XMLPROJECTION = "ANY") [ SqlFieldName = _any ];

]]></Content>
</UDLText>

When imported and compiled into an Ensemble instance this class works as expected.

When viewed/edited in a development environment we run into issues - the presentation is similar with both Studio and VS Code.

Windows 10/Windows Server 2016:

I am currently monitoring our license use with a new rest-service I am implementing when I noticed my licenses on my instance being consumed and never released by Visual Studio Code.

For this I restarted my Instance, watched the licenses for a while, which remained at 1 during idle (I am guessing my MMGT Portal session uses 1) 
But when I connect to my Instance using Visual Studio Code (with my Instance setup in the extension already), suddenly 2 licenses are used.

I added extra OBX segments and I need to renumber OBX 4 so they are sequential.

I know that people who are completely new to VS Code, Git, Docker, FHIR, and other tools can sometimes struggle with setting up the environment. So I decided to write an article that walks through the entire setup process step by step to make it easier to get started.

I’d really appreciate it if you could leave a comment at the end - let me know if the instructions were clear, if anything was missing, or if there’s anything else you'd find helpful.

The setup includes:

✅ VS Code – Code editor
✅ Git – Version control system
✅ Docker – Runs an instance of IRIS for Health Community
✅ VS Code REST Client Extension – For running FHIR API queries
✅ Python – For writing FHIR-based scripts
✅ Jupyter Notebooks – For AI and FHIR assignments

Before you begin: Ensure you have administrator privileges on your system.

In addition to reading the guide, you can also follow the steps in the videos:

For Windows

To VSCode experts - see the screenshot. When right-click on a method with intentions to proceed to the source code:

I am always confused about what to choose: declaration or definition. What is the difference?

I was using VSCode to edit a DTL because it seemed easier to copy/paste code from parts of the DTL I was editing. I tried to add <sql> tag and code to call a SELECT statement, but when I compiled I got the following error...

ERROR <Ens>ErrInvalidDTL: Invalid DTL

  > ERROR #5490: Error running generator for method 'GetSourceDocType:osuwmc.Epic.MFN.DTL.EpicMFN949002Normalization'

ERROR: Ens.DataTransformDTL.cls(GetSourceDocType) of generated code compiling subclass 'osuwmc.Epic.MFN.DTL.EpicMFN949002Normalization'

    > ERROR #5030: An error occurred while compiling class 'osuwmc.Epic.MFN.

The VS Code extension development team is looking for beta testers to provide feedback on a proposed overhaul of the client-side editing workflow. The full list of changes can be found in the GitHub pull request description. Here are the highlights:

• Support the use of client-side editing in any non-isfs workspace folder, not just folders in your local file system. For example, with VS Code Remote Development.
• Create an index of all Classes, MAC and INT routines, and Include files inside non-isfs workspace folders.

Have you ever been editing files in VS Code, but needed to check a global value or run a few ObjectScript commands? Now you can, with no setup required! If you have vscode-objectscript extension version 2.10.0 or later and are connected to InterSystems IRIS 2023.2 or later, you can now open a terminal connection to your server, regardless of where it's located.

As you may know, the so-called Private Web Server that came with every IRIS installation has been eliminated, making an external web server necessary.

For Docker deployments, it's most common to use the webgateway image (available here) along with the IRIS image to seamlessly access the management portal. This image can be configured to access via HTTPS without any issues by configuring the certificates.

Problem 1: Unable to verify the first certificate

Your SSL connection through the web gateway may have a self-signed certificate configured, and Visual Studio Code is attempting to verify it.

Visual Studio Code releases new updates every month with new features and bug fixes, and the February 2025 release is now available.

There have been enhancements to GitHub Copilot with predictive editing, autonomous task completion, smarter code search, improved terminal and notebook support, and UI and workflow refinements.

Highlights from version 1.

The compile step in VS Code when using the InterSystems VS Code extensions appears to modify line endings in our class files when newly pulled from remote repo.

What steps can we take to stop this happening? / What settings can we modify?

We are doing local development with client side source control using git (BitBucket Cloud repository). We were previously using GitLab (locally hosted) and didn't have this issue. Developers are all on Windows machines, as are all the Ensemble instances. We believe we have autocrlf = true in all our local git configurations.

ISCLOGs are a useful debugging tool provided with IRIS that can help you troubleshoot many different issues. For more information about creating these logs, please see the following IRIS documentation: "Logging".

This log is written to the ^ISCLOG global stored in the %SYS namespace. Each global node is a separate event, with additional information sometimes logged to the subnode.

Each entry consists of a list containing the following fields: ID, Category, LogLevel, Message, Namespace, Process ID, Routine, SessionID, Tag, and, TimeAdded

Hi - Recently I have been investigating an annoying situation whilst editing ObjectScript classes or routines in VSCode.

What was happening to me was, as I was typing in lines of code into my class (for example, adding a new Method, or changing the Class signature, or a block of code),  this would quickly get syntax checked, re-formatted, and compiled - inevitably, (since I would be mid-way through my typing), this would generate compilation errors.

Hi Community,

Watch this short exercise in writing basic code snippets in InterSystems ObjectScript using Copilot in VSCode and the GPT-4.0 engine. This screencast covers "Hello, World," global manipulation, class creation, and building a simple REST API application.

Hi all!

In this article I would like to review those VS Code extensions which I use myself to work with InterSystems and which make my work much more convenient. I am sure this article will be useful for those who are just starting their journey to learn InterSystems technologies. However, I also hope that this article could be useful for experienced developers with many years of experience and open up new possibilities for them when using VS Code for development.
