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.
PHP, from the beginning of its time, is renowned (and criticized) for supporting integration with a lot of libraries, as well as with almost all the DB existing on the market. However, for some mysterious reasons, it did not support hierarchical databases on the globals.
Globals are structures for storing hierarchical information. They are somewhat similar to key-value database with the only difference being that the key can be multi-level:
Object Synchronization is a feature that has been around for a while, since Caché days, but I wanted to explore a bit more how it works. I've always thought that database automatic synchronization is complex by nature but, for some particular scenarios shouldn't be so hard. So I considered a very simple use case (OK, perhaps the typical one, I'm not discovering anything... but if it's common and it works, it's good ).
Watch this video to get an introduction to data types in InterSystems ObjectScript, and see how to use three common data types: strings, lists, and objects:

I had attempted to create a REST Operation before but did not have success. As I am going through the Tutorials and Documentation everything references REST services, but I have a case where I want to create a REST Operation that makes Epic API calls against Interconnect. I have done SOAP operations before and we currently have one in our Production Namespace, but from what I understand SOAP has the wsdl which defines al the structures and etc, where REST does not.
Here in %SYS, we have already examined users, resources, and roles. Now that we know how to set all of that up, we should give it a purpose. Next we will talk about applications! As you may expect, we will see various identical class methods defined here that we have seen in the previous classes. However, some of them will have some tiny yet significant differences.
I have some constants hardcoded in my class as parameter values, and those constants are referenced in many places in my module. Now the need has arisen to provide different value for those parameters depending on some context. Is it possible to create some sort of accessor method for the parameter (like it is possible for properties), or do I need to perform a thorough refactoring?
We are developing a Transformation and we are wondering: how could we debug and show a XML message which is being an output from a transformation, without storing it into request/response/callrequest/callresponse? We mean, how could we show a context variable in the production?
For example, let's have a transformation which stores an appointment in a variable called: context.especializadasConFormatoPrimarias
How could we show in the Production?
Currently it is being stored as the Transformation's output:
Surely there is an easy way to invoke a ClassMethod from a DeepSee detail listing line, in a similar way to launching a URL. In this case I need to do a little preprocessing of a request adding a SAML token.
I thought I knew how to do it long ago, but I can't read my faded notes on that old parchment.
It would be interesting if there is some recommended documentation about best practices using Healthshare for interoperability.
Also, some how-tos or frequently asked questions about ObjectScript.
Or event better, if there are experienced developers who would like to share some common habits on their work with Studio / ObjectScript, which are valuable to do the developing work better.
For example, How to get the XML of a class and write it into a REST operation:
I need to create a util function that loops thru every character in the data, execute a $ASCII() against it. If it falls outside the realm of extended ASCII we toss it.
the function should receive a string, execute a for...loop across it's length and use $ASCII to evaluate the character. Also the function should return an output argument that indicates if the string is UTF8 valid or not.
This example demonstrates the difference you may experience when you write to Gllobals directly from Embedded Python compared to native ObjectScript.
To make this demo useful I start 2 background jobs that simply write sequentially to a dedicated global. A common control method signals for a synchronous start. Similar a common stop & view interrupts data feeding.
I have created a HL7 production in my working environment, Ens.Alert ,EMailAlert, PagerAlert, and BadMessageHandler are created.
Can anyone explain how Ens.Alert and BadMessageHandler will work when an HL7 message in Passed in Business service and how these 2 are related when any error occurs in the Production envinorment?
Have successfully installed the Intersystems ObjectScript Extension Pack (version last updated 2024-03-26) in VS Code version 1.88 and when creating a new Class (in a New File of type ObjectScript-class) I am presented only with the following snippets:
Is there documentation that shows the mapping between the management portal components and object script package.class.methods? I am searching on-line documentation but have not been successful. For example, in the management portal SystemOperation > TaskManager > TaskSchedule can map to the method: class(Monitors.Tasks).ListSuspendedTasks().
What would be a similar mapping for SystemOperation > TaskManager > TaskHistory? I initially thought it would be something similar to class(Monitors.Tasks).ListTaskHistory().
I want to disable / turn off the visible cursor and then re-enable from with a Cache MUMPS (COS) routine. Can anyone advise please ? I am using the free Intersystems Cache installation (CachePCkit V2017.1) on Windows 10 for my own use & personal development.
