My colleagues and I were wondering why the varstring class is hidden in the Intersystems documentation. Is it "safe" to use ? We tried looking it up in the forum and it seems like it is used by other developpers. Is there anything we should know before using it ?
Hi. This is my first post on this forum; I've tried to open an issue on the official repo , but it seems inactive from more than a year, so I can't receive an answer from there. I would like to know if someone use that extension and know how to use it when working server-side on an IRIS server. I have no problem when coding on a file saved locally. Thanks in advance
An extension “extends” or enhances a FHIR resource or a data element in a custom way. The extension can be added to the root of a resource, such as “Patient.ethnicity” in US Core profile, and they can be added to individual elements such as HumanName, Address or Identifier.
Did you know that you can also add an extension to a primitive data type?
Primitives usually store a single item and are the most basic element in FHIR. For example: "Keren", false, 1234, 12/08/2024 etc.
For example, the patient resources might look like this:
As we keep updating our software, we often realize that we require more and more modern solutions. So far, only one major piece of our software relies on reading barcodes in documents and images. Since Cache did not have a means of reading barcodes in the past, we have always achieved our goals by using a Visual Basic 6 application. However, it is no longer an ideal solution because it is currently complicated to maintain it. IRIS also lacks this capability, but it has recently got an option that makes up for it: embedded Python!
Many programming languages use the try-and-catch construct to handle runtime errors gracefully. If the code within the try block encounters an error, it will throw an exception to the catch block, where the error handling occurs.
We are in the process of migrating from Ensemble to IRIS.
After the migration I would like to find all usages of deprecated classes and methods in all of our code. This is to align with the changes in package like %SYSTEM.SQL for example.
Is there an easy way to do this, or maybe a tool that can assist?
I have a problem with my script, In another code it works fine, but in this script It not display anything in InterSystems portal, when I try to debug, it gives the data, but why in portal it show nothing?
When I'm writing code in Intersystems Studio code completion is different than in VS Code. It would be greate if VS Code would react the same way on code completion .. This happens is studio
When I do this in VS Code it doesn't show the object but it shows ?? all possible items ??
The topic of for/while loop performance in Caché ObjectScript came up in discussion recently, and I'd like to share some thoughts/best practices with the rest of the community. While this is a basic topic in itself, it's easy to overlook the performance implications of otherwise-reasonable approaches.
Before we start with some intermediate and advanced topics, I would like to sum up some more general points. They are subjective, of course, so I will be happy to discuss them if you have other opinion or better arguments for any of them.
The list is not comprehensive and this is intended, cause I will cover some topics in future articles.
Mixing Object syntax with SQL is one of the nice features in Object Script. But in one case, it gave strange results, so I decided to isolate the case and describe it here.
Let's say you need to write a classmethod that updates a single property on disk. Usually, i would write that using SQL like this :
Hi! Today I would like to talk about one of the most important architectural patterns in Angular.
The pattern itself is not related to Angular directly, but as Angular is component-driven framework, this pattern is one of the most essential for building modern Angular applications.
Container-Presentation pattern
It is believed that good components should be small, focused, independent, testable and most important - reusable.
I have created a Class method to list employees that are subordinated to a certain boss. But I don´t know how to relate the data in the way it was given to me.
Hi! I am working on a project where I use record map to transform a flat file and split it into two output text file and in the future will need to split four output files.
I only want to use one target business operations instead of multiple. Is there a way to set the output file and the target folder path in my business process class?
Any advice on how I can achieve this or is this possible? Thanks!
Our organization is looking to expand our Coding Standards to be more in alignment with best practices.
I was wondering if the there are developers here that would not mind sharing any existing documents. Our scope would be this document be applicable to new hires learning Cache all the way up the chain.
Is it possible generate HTML documentation to my project ObjectScript classes (.cls)?
In Java we use Javadoc to do it. Javadoc get class comments and java metadata information and when I execute javadoc -d doc src\*, I get whole html documentation to my classes. Has IRIS something like javadoc? Is it documatic? If yes, how can I use it?
I have multiple files with different columns, first 9 values are fixed, so i want to ignore the first value, and next 8 values i want to combine into one value using ^ sign
Any syntax help, i want to check different msg types and then reach out to the value in that particular segment. Here is example, i want to get SSNNumber from a method. Trying to use NOTIN, and Lookup

I work on deploying IRIS inside Docker container. I really like %Installer class can automate many steps. I want to establish an ECP connection to a mirror database and then define a remote database on the application server. I have already seen we can create local database and namespace in %Installer. What code is needed to establish ECP connection?
