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.

Hello all, I have a question about constucting thousands of clones, and scope.
In my code, I'm looping through a database, say 200k+ objects, and creating a clone of each object (we need to evaluate a modified clone of the object, but not account for what's on disk).
In this edition of InterSystems IRIS2020.1 Tech Talks, we put the spotlight on Integrated Development Environments (IDEs). We'll talk about InterSystems latest initiative with the open source ObjectScript extension to Visual Studio Code, discussing what workflows are particularly suited to this IDE, how development, support, and enhancement requests will work in an open source ecosystem, and more.
As discussed in previous parts of Package Manager stories to turn your IRIS application into a deployable package you just need to introduce the module.xml file into the root folder of the repository and describe all the resources.
I’m pleased to introduce you to a new project template on Open Exchange which contains examples of how to make different types of resources of your InterSystems IRIS application a part of the ObjectScript package and so make the deployable ObjectSctipt package.
Let's see how you can describe your application resources using this template project as an example.
Using the IRIS native API for Node.JS was the opportunity to present a MicroService operating in a Docker container. A demo video is now also available to watch the demo in operation.
I have a class that writes to an external SQL Server database. When the field is empty, it does not write the column and the column has the value NULL. In some cases, I want the column to be the value of the empty stringinstead of NULL.
So we have seen that we could create a class, to sign a document, and store the sign inside that new class. We have also seen that there are some different algorithms to choose from, like sha1.
I have a bit of code that does a find and replace on a "template" and inserts additional content. For example it replaces the @DATA@ with an html table:
We are getting CoClass not available [80040111] when using %Net.SSH.Session. Does anyone know if there is a security setting that would disable this object?
If you define a Persistent Class / Table the class compiler generates for you an appropriate Storage definition. A different option is to define a SQL mapping for an already existing Global storage. This has been excellently explained already in a different series of articles. The Art of Mapping Globals to Classes 1 of 3
I believe the simplest is (to work with csv delimited by ";"):
set file = ##class(%File).%New( "data.csv" )
set sc = file.Open( "R" )
if $$$ISERR(sc) quit ; or do smth
while 'file.AtEnd {
set str=file.ReadLine()
for i=1:1:$length( str, ";" ) {
set id=$piece( str, ";" ,i )
write !, id // or do smth
}
}
do file.Close()
Possible options:
different variants of error handling with sc code.

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.
Hope most of you already familiar with project CachéQuality from @Daniel Tamajon. For those who don’t know about it, it is a static syntax analyzer for your code written for InterSystems products. It may help you to find and solve many different types of issues in your code, and even possible bugs before clients will find it in production. So, with help of CachéQuality you will be able to deliver a better product. You can find the complete list of rules used to check ObjectScript code here.
It was already available in Studio. And now it is also available in VSCode.
Some weeks ago, I was reading a book by Stephen Hawking and Leonard Mlodinow, The Grand Design. At a certain point, trying to define why do we exist? , why do we use the models we use in physics?, ...those kind of things you know... they pointed at the Game of Life example invented by the mathematician John Coward in 1970... Basically he wanted to show that a system with really basic fundamental laws (Physics) could evolve and "live" to become a more complex system (Chemistry) in which "something" (humans) could work out its own model and complex rules to explain its reality… the rules for this deterministic model that he exposed were so basic that I thought it could be funny to implement them in ObjectScript when I had some spare time... there are others implementations in JavaScript and other languages... but not in ObjectScript... and that had to be corrected!!… so here you are!
I'm new to the Intersystems development world and I've been trying to figure out how to make a REST API using ObjectScript. I found a tutorial that I've been following that has been great and I'm trying to translate what I've learned to live data.
Are there any tools to check the code coverage and to do a lint check for cache object script? Developers will be working with HealthConnect (IRIS based)
