ObjectScript Search — Full-Text Server-Side Search for VS Code, Right Now

ObjectScript Search icon

If you have ever dug through a large IRIS namespace looking for where a particular string, method call, or pattern was used, you know the pain: there was no built-in way to do a grep-style search across your server-side ObjectScript code from VS Code — at least not without jumping through some hoops.

That is what ObjectScript Search fixes.

Try it today with a simple install from the VS Code Marketplace. If you don't like it, uninstalling is just as easy. But I think you will like it — it is a huge quality-of-life improvement for anyone doing ObjectScript development in VS Code.

FastHTTP : Simplify Your HTTP Requests in ObjectScript

Introduction

The standard %Net.HttpRequest library in InterSystems IRIS is powerful and comprehensive, but it can be verbose for simple operations. Writing an HTTP request often requires several lines of code to instantiate the class, configure the server, the port, HTTPS, add headers, and finally send the request.

When testing in the terminal, this configuration quickly becomes too heavy, and usually ends up with the creation of temporary methods...

Taking up Collections in IRIS

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.

Cleaning up EnsLib.SQL.Snapshot in BPL's

We are trying to track down significant growth within our Namespaces, one big culprit is Ens.AppData (EnsLib.SQL.Snapshot). 

Within many of our BPL's we use EnsLib.SQL.Snapshot to return Results from External SQL Stored Procedures or Query's. The same EnsLib.SQL.Snapshot context variable is used for many of these calls within a BPL. 

Is there something we should be doing at the end of the BPL to ensure that EnsLib.SQL.Snapshot gets cleaned up and purged from Ens.AppData?

Leveraging External FHIR Repository Patient.Search (R4) to Address Missing Data Elements in HL7 Results

Background

Emergency Medical Services (EMS) teams often arrive at the emergency department with patients whose demographics are incomplete or unknown—no medical record number (MRN), no confirmed name, and sometimes no date of birth. Yet EMS transportation notes still need to land in the correct chart.

To support safe and reliable documentation, EMS agencies, third-party integration services, and hospital integration teams build secure interfaces that exchange identifiers and clinical messages.

¿How to execute a stored procedure in a remote DB2 database?

How to execute a stored procedure in a remote DB2 database?

Hi Everyone,

I want to access a stored procedure in a remote DB2 database. The stored procedure in question is linked and receives a numeric value, returning a cursor with N number of rows. Sometimes the number of rows reaches hundreds of thousands, so I need to apply pagination.

I've been reading about the %ScrollableResultSet library, but it doesn't allow me to call a stored procedure.

Here's part of the code:
Set pValor=12345678
Set callSql="CALL Paquete.ClaseSpRemoto(?)"
Set rs=##class(%ScrollableResultSet).

Dynamic SQL Query using Linked Table Help

I am stuck at a crossroad and was wondering if I could get a second pair of eyes to help with a query that I am sending from a Task to a Service to process some data.

I have a Linked Table (view) that points back to a MS SQL View that I am trying to query. However, my execution keeps either failing or not returning any rows. When I take the SQL Query and execute it within the Management Portal I get results, however Cache is not seeing it when trying to execute this code.

Stop vs code trying to auto log in to all workspace folder

When using VS code with multiple workspaces it requests "The extension 'InterSystems ObjectScript' wants to sign in using InterSystems Server Credentials. 

Other than having multiple workspaces per environemnt (which never really works for me in principle as i end up code comparing in one manner or another) is there a way to only have intersystems log in to VS code whenever you open an actual workspace itself i.e. click on dev not on loading vscode. 

This would also get around errors of "unauthenticated access rejected by" errors as VS code tries to log in without the password first.

Exposing a Basic REST API with InterSystems IRIS: Step-by-Step Docker Example

Introduction

InterSystems IRIS allows you to build REST APIs using ObjectScript classes and the %CSP.REST framework. This enables the development of modern services to expose data for web apps, mobile apps, or system integrations.

In this article, you'll learn how to create a basic REST API in InterSystems IRIS, including:

  • A persistent data class
  • A REST class with GET and POST methods
  • A web application to expose the API

  • A full demonstration using Docker

Clinical Staff Master Data Management with RESTful APIs and Dynamic Mapping on InterSystems IRIS for Health

Project Overview:

The Clinical Staff Master Data Management (CSMDM) system is a full-stack healthcare integration application built on InterSystems IRIS for Health. It centralizes and standardizes clinical staff metadata into a single authoritative repository, exposed through RESTful CRUD APIs and reusable backend methods.

The platform eliminates fragmented lookup tables and hardcoded mappings that commonly cause errors in HL7 and FHIR integration workflows, ensuring data consistency and interface reliability.

I'm testing vibecoding with ObjectScript and my silicon friend created a code-block that got me thinking "what's wrong"?

Here is the piece of code:

AI wanted to quit from a method with a return value. Good intention, but bad use of the command.

And ObjectScript compiler compiles this code with no error(?) (syntax linter in VSCode says it's a syntax, kudos @Brett Saviano ).

But in action, it produces <COMMAND>, of course.

API Unit Testing with CSP Requests and Reponses

In the previous article, we examined how we can use the %CSP.Request and %CSP.Response classes to test a REST API without having the API fully set up and accessible across a network with an authentication mechanism. In this article, we will build on that foundation to perform some simple unit testing of one of our REST API methods.

The unit testing framework requires a couple of setup steps before we can use it. First, we have to ensure that the unit testing portion of the management portal is enabled so we can review the results of our tests.

ClassMethods Are Not Your Friends

There seems to be a generous use of ClassMethods in ObjectScript code generally. I hope my own experiences aren't representative, but I bet they are. Forgive me for giving away the ending of this article, but in short: don't use them. Unless you can make a pretty convincing case that you have to, just never use them.1

What is a ClassMethod? In an ObjectScript class, you can define methods in two different ways: in a Method, you must instantiate an instance of the class to call the method, and in a ClassMethod, you can call the method without instantiating the class. Of course, in a ClassMethod, you don't have access to any properties of the object (because there's no object), but you can access globals (they are global, after all) and Parameters (which are class constants).

However, when I try using the "ObjectScript" plugin to export the project (right click on the project -> "Export Project Contents")

This message appears and it is not possible to export the project:

I've tried also to open a new window, then a folder and finally the project, but nothing changes. 

This is an example of my workspace: 


Anyone knows how to do it?

The goal was simple: take an existing, well-known persistent package in IRIS and quickly build a usable UI and API around it — letting AI handle as much of the boilerplate as possible.
