Hello fellows, I need you wisdom.

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.

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.

Hi Folks,

I created a persistent class as below 

Class myclass.DataBase Extends %Persistent
{

Property ID As %String;

Property Skill As list Of myclass.SerialTablelist;
}

and Created another Serial class as 

Class myclass.SerialTablelist Extends %SerialObject
{

Property PSkill As %String;

Property OSkill As %String;
}

Now I will save the id as below

do rs.Prepare("Insert into myclass.DataBase(ID)VALUES(?)")
do rs.Execute(ID)

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.

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 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.

Hi Developers!

Sometimes we need to import CSV data programmatically to InterSystems IRIS either from CSV or from URL. And we expect the class with proper datatypes to be created and the data to be imported.

I published a module csvgen on Open Exchange which does exactly that.

If you just need the CSV file be imported into IRIS you can do the following:

USER>do ##class(community.csvgen).Generate("/usr/data/titanic.csv",,"Data.Titanic")

Class name: Data.Titanic
Header: PassengerId INTEGER,Survived INTEGER,Pclass INTEGER,Name VARCHAR(250),Sex VARCHAR(250),Age INTEGER,SibSp INTEGER,Parch INTEGER,Ticket VARCHAR(250),Fare MONEY,Cabin VARCHAR(250),Embarked VARCHAR(250)
Records imported: 891
USER>

Or if you have the CSV on the internet, e.g. COVID-19 Data on Github you can get the data in the following way:

USER>d ##class(community.csvgen).GenerateFromURL("https://raw.githubusercontent.com/CSSEGISandData/COVID-19/master/csse_covid_19_data/csse_covid_19_daily_reports/05-29-2020.csv",",","Data.Covid19")

Class name: Data.Covid19
Header: FIPS INTEGER,Admin2 VARCHAR(250),Province_State VARCHAR(250),Country_Region VARCHAR(250),Last_Update DATE,Lat MONEY,Long_ DOUBLE,Confirmed INTEGER,Deaths INTEGER,Recovered INTEGER,Active INTEGER,Combined_Key VARCHAR(250),Incidence_Rate DOUBLE,Case-Fatality_Ratio DOUBLE
Records imported: 3522
USER>

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.

Hi

I'm using a class which extends %XML.Adaptor adaptor and I want to create an XML file with multiple namespaces, like the following:

<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
</soap>

However, I don't see how to do this with the code I have. So far, I have
