InterSystems ObjectScript is a scripting language to operate with data using any data model of InterSystems Data Platform (Objects, Relational, Key-Value, Document, Globals) and to develop business logic for serverside applications on InterSystems Data Platform.
I would like to share a small part of my learnings from my first ever official project: POS/EDC machine integration with our billing system. This was an exciting challenge where I got hands-on experience working with APIs and vendors.
How does a Payment Machine actually work?
It's simple, start by initiating/creating a transaction, then retrieve its payment status.
Here, initiate/create refers to POST methodand Retrieve refers to GET.
I'm pleased to announce version 2.6.0 of the VS Code ObjectScript extension, containing a number of enhancements that make a developer's life easier. Some highlights are described below. As always, find the full list of modifications in the CHANGELOG, including many bug and vulnerability fixes.
i am looking for a Class or Function to check if a Base64 document is valid ( will results into Full file after decoding or not ), i was not able to find any predefined class in Objectscript ,
has anyone worked on something similar before ? any advice will be welcomed
I would like to share with you a little trick to customize how messages are displayed in the Message Viewer. In particular, how you can display messages as JSON (instead of the default XML representation).
When using a EnsLib.RecordMap.Service.FileService business service, is there a way to tell which row number that is being read in? I want to read in a csv, but on the first record, trigger a truncate on the External SQL Table that it is being written to through JDBC.
In this article, we will explore the concepts of Dynamic SQL and Embedded SQL within the context of InterSystems IRIS, provide practical examples, andexamine their differences to help you understand how to leverage them in your applications.
InterSystems SQL provides a full set of standard relational features, including the ability to define table schema, execute queries, and define and execute stored procedures. You can execute InterSystems SQL interactively from the Management Portal or programmatically using a SQL shell interface. Embedded SQL enables you to embed SQL statements in your ObjectScript code, while Dynamic SQL enables you to execute dynamic SQL statements from ObjectScript at runtime. While static SQL queries offer predictable performance, dynamic and embedded SQL offer flexibility and integration, respectively.
As a developer who uses Cache as DB for a couple of projects, I'm using REST API's every time, knowing how to consume a resource from REST API, in my opinion, it's crucial to know how to consume external REST Api's using %Net.HttpRequest because it enables integration with modern web applications and services, and it's a crucial skill for a backend developer who loves and uses Cache as a DB.
My guess is that most IRIS developers create their applications using its native ObjectScript language or, if using an external language, then most likely using either Java, Python or perhaps C++.
I suspect that only a minority have considered using JavaScript as their language of choice, which, if true, is a great shame, because, In my opinion and experience, JavaScript is the closest equivalent to ObjectScript in terms of its ability to integrate with the IRIS's underlying multi-dimensional database.
Over time, while I was working with Interoperability on the IRIS Data Platform, I developed rules for organizing a project code into packages and classes. That is what is called a Naming Convention, usually. In this topic, I want to organize and share these rules. I hope it can be helpful for somebody.
I am looking to view the contents of the request object I am sending from my Service into my BPL in Message Viewer. My request contains references to other defined classes.
$System.Util.GetEnviron("USERPROFILE") returns "C:\WINDOWS\system32\config\systemprofile". I don't know what that is, but that folder doesn't even exist. The correct value which I need is "C:\Users\robert.steed", as seen via the Windows command line "set" command.
Starting out with ObjectScript, it is really exciting, but it can also feel a little unusual if you're used to other languages. Many beginners trip over the same hurdles, so here are a few "gotchas" you'll want to watch out for. (Also few friendly tips to avoid them)
NAMING THINGS RANDOMLY
We have all been guilty of naming something Test1 or MyClass just to move on quickly. But once your project grows, these names become a nightmare.
The ObjectScript language has incredible JSON support through classes like %DynamicObject and %JSON.Adaptor. This support is due to the JSON format's immense popularity over the previous dominance of XML. JSON brought less verbosity to data representation and increased readability for humans who needed to interpret JSON content. To further reduce verbosity and increase readability, the YAML format was created. The very easy-to-read YAML format quickly became the most popular format for representing configurations and parameterizations, due to its readability and minimal verbosity.
I was really surprised that such a flexible integration platform with a rich toolset specifically for app connections has no out-of-the-box Enterprise Service Bus solution.
Managing IAM can be tedious when done manually — especially when your APIs are already well-documented using OpenAPI (Swagger) specs. Wouldn't it be great if you could automatically generate Kong services and routes directly from your OpenAPI spec?
That's exactly what this ObjectScript method does: it reads an OpenAPI 2.0 spec stored in the XData block of your spec class and generates a decK-compatible YAML file that can be used to sync your IAM configuration.
The ^%GCMP utility can be used to compare the contents of two globals.
For example, to compare ^test and ^test in the USER and SAMPLES namespaces, it would look like this: *In the example below, 700 identical globals are created in the two namespaces, and the contents of one of them is changed to make it the detection target.
I’ve been exploring options for connecting Google Cloud Pub/Sub with InterSystems IRIS/HealthShare, but I noticed that IRIS doesn’t seem to ship with any native inbound/outbound adapters for Pub/Sub. Out of the box, IRIS offers adapters for technologies like Kafka, HTTP, FTP, and JDBC, which are great for many use cases, but Pub/Sub appears to be missing from the list.
