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.
In my organization we code in ObjectScript and .int everyday. When I joined nobody knew barely nothing about classes and their use was almost only for storage definition purpose. During my self-learning in caché I discovered the object oriented programming and class developing was possible in caché and started to code in .cls . Being something self-taught, I may have some basic doubts I'd have missed in my documentation readings.
I'm using %XML.Writer to write XML files from a database source, and I see that it is not encoding carriage return or line feed as 
 and 
 respectively, and is instead leaving them unencode.
Is there a straightforward workflow in VS Code for moving a class from one namespace to another on the same server? With Caché/IRIS Studio, it was a (sort of) simple export/change namespace in file menu/import operation. But in VS Code it's not obvious (to me, at least).
I can add multiple namespaces to a workspace, but when using isfs:// paths I see only a "Download" option and no "Upload" or "Import/Compile." When I'm navigating the local file tree, I see Import options, but no way to select the namespace into which I want to import.
I will give you some additional information on my first embedded Python package. it is written as a mix of python and ObjectScript to take the best of both worlds.
Hi all - we just released the first episode of Season 2 for our Data Points podcast by Learning Services. This episode features a conversation with @Bob Kuszewski about Embedded Python. If you're a Python developer, or if you're simply interested in the functionality, check it out! For more information, head over to https://datapoints.intersystems.com.

What is the SQL table name for it? How can I obtain it via ObjectScript?
A quick search doesn't show any methods and properties. Documentation is a bit "wrong" here saying that the SQL table name is the same. It will be at least 'x_y.z'.
I'm trying to write a method that runs an OS command with $zf(-100,"/ASYNC") and then waits for it to finish before returning, but I can't figure out how to check if the child process (in $zchild) is still running. $System.Process.State($zchild) always returns "RUN" even once the child process is gone. Is there some better way to check this, short of running another OS-specific command and processing the output (which is just really annoying and unelegant)?
Hi, I am trying to work with visual studio with the extensions offered by InterSystems, but I can't find any option to work locally, is there any way to do it?
I am using VSCode together with IRIS 2021.1. When using Shift+Alt+F to reformat a class file, it pops up with the below message. When I select install formatter, it routes me to the extensions page, where it shows the extensions as being installed. Any advice will be appreciated.
For some years I missed being able to offer, to everybody interested in ObjectScript, a tutorial more or less complete, to start with ObjectScript. Something that could help more and make things easier to those new developers that come to our technology... something intermediate, halfway between the common "Hello World!", that doesn't really get you further, and the "Advanced Training", that is unaffordable because of lack of time,etc.
If there were something truly helpful not only as an introduction to the ecosystem, but as a starting point, as a boost, to really start to walk into ObjectScript and move forward by yourself... wouldn't that be awesome?
So I've been reviewing a lot of questions posted in the InterSystems community regarding NULL properties in JSON. I've also been reviewing the JSON documentation. None of these things have been able to help me so far.
1. We don't seem to have the %JSON.Adaptor class available for us to use in our system.
2. I'm not really confident enough to create JSON Type classes or backporting code, etc.
Recently, I needed to create templates for newsletters. I couldn't find any tools, so I decided to use the CSP (Caché Server Pages) to build the templates.
Let's figure out how to make a newsletter similar to Weekly OEX Digest.
We have a couple of systems that send us a URL link to a PDF instead of base 64 encoding it in the HL7 message. Has anyone ever tired to take that URL, and retrieve the file off of the server to save it off somewhere?
Thanks to everyone for participating in the Advent of Code 2021and coding in InterSystems ObjectScript! We're pleased to introduce the winners and distribute all the prizes!

I was editing the properties of a persistent ObjectScript class the other day and noticed that the storage definition wasn't updating to reflect my latest changes.
In this case, I deleted a property that was no longer needed from the class definition, saved, recompiled, and still saw it in the storage definition.
I've found a couple of methods that will tell me whether a package is mapped from another database, but not which database. Is there such a method/routine?
I have an auditing class that defines some sqlComputed properties and can be extended by other persistent classes to enable auditing of its properties.
I'm curious if it is possible to change the class method to another class?
I call a method of a system class to generate another class. But there is a bug/feature in a library class, so I need to tweak a bit the generated method, e.g. add additional parameter and change the line to "if" the parameter.
I hope to do this programmatically after class generation and change the code in a way I like.
I noticed something interesting in regards to business rule editing. Whenever you use the Management Portal or Studio to edit a business rule, the " characters gets escaped to a ".
I need to store an equivalent of the SNN (Social Security number). I need it to be encrypted and I'll have to be able to search for it once stored.
For what I've seen my options are:
- SHAHash from the %system.encryption library. Simple and easy to implement. My question is, might collisions be a problem? We are talking about a 10 millions entry.
- AES encryption. In this case I'd like to know if there is a standard way for key management in the InterSystems environment.
