#ObjectScript

Hello,

I am trying to grab a specific zip file from a webpage but once I grab the zip file I need to grab a specific file within that zip file and I was hoping someone could explain how to do this or provide an example

With $Property is possible to dynamically get and set values on property of an instanced class and with $ClassMethod is possible to invoke methods from a class. I would like to know: Is there an elegant way to do Write and Set dynamically on variables without using Xecute?

Hi everyone,

I'm having trouble parsing XML containing unicode characters which I receive from an external webservice. I believe my file is saved properly with UTF-8 encoding but the SAX Parser still throws me an error.

I have 2 classmethods: 1 general one (get) to make a request to a webservice and return the date, and 1 (getSportsPerDate) to make a specific call and then parse the data.

ClassMethod getSportsPerDate(language As %String, date As %String){
    #dim cResponse As betradar.uof.api.descriptions.schedule.scheduleEndpoint    #dim res As %Stream.FileCharacter    s res=.

Hi, devs!

Consider you have an arbitrary global with an unknown amount of indexes.

How to print all the values to the terminal with Embedded Python?

Hi folks!

I'm working with a global via Embedded Python as a class method. I init the handler for a global via:

gl=iris.gref("^Global")

What is the way to check the value at index ^Global("x","y")? E.g.:

In ObjectScript I'd do the following:

set result=$data(^Global("x","y"))

How do I do the same in Embedded Python?

I checked the documentation, but haven't found an answer.

Issue

Breakpoints do not work when using VS Code Debug this method feature on a ClassMethod. Debug runs like normal and I can sometimes see 'running' on the CALL STACK menu. In the BREAKPOINTS menu, the breakpoints will start red, like normal, but eventually turn gray. On-hover for a grey breakpoint is the message "Breakpoint Cannot Be Mapped". After the method finishes, the breakpoint turns red again. No error messages appear. This is an intermittent issue, as sometimes it runs fine. So far, I have not been able to figure out the conditions to re-create this issue.

Any suggestions?

If your handling XML then it can often be unformatted for human display.

Using a little bit of XSLT magic you can format the XML in just two lines of code...

When using VS Code for Objectscript, is there a way to directly open % classes, like %Library.String, without needing to search for a property of that type and right clicking->"Go to Definition"?

I know it is possible to use "system=1" in the workspace uri definition to see all the % classes, but that tends to clog up the left side viewer with many extra directories. There is also the option in the settings to selectively hide some by defining files.exclude, but it seems fairly complicated to set up a filter for exactly the relevant directories.

So does anyone know the best workaround?

Hi, ObjectScript experts!

I know that there are auto-generated getter and setter methods for class properties in ObjectScript.

Are there auto-generated getter methods for class parameters?

Hi folks!

We have a bunch of templates on OEX that provide a handy foundation for building a particular application with IRIS.  And the basic principle of each and every template is that we take vanilla IRIS images, load code, and files into the image using Dockerfile, and create a new docker image as a solution. And then we develop running this image and rebuilding it when returning to development.

Some developers ask me why we need to build the docker image to work with the code. Indeed, if at the end of the day I need to develop a ZPM package and not a docker image why don't run the vanilla image and load the code and everything in it? 

The problem I have with the building image approach is that often I can wait a lot to build an image and it fails on some Objectscript problem in the source that I cannot fix as the image is not building. and 

Any thoughts? How do you develop with docker?

Hi,

Let's consider these two ways of passing an obj to a function:

//var is a structured obj
(1) do ..methodX(var)
(2) do ..methodX(.var)

In c++ if we pass an obj by reference like in (2) we save a lot in computation because we are not copying the whole object, and when the object is modified within the function it is modified also for everyone.

In this case does (2) achieve any better performance than (1)? Is passing with the "." save any computation? the object is copied anyway?

Is there a simple way of passing obj to a function?

 Hello Community!

This article gives an overview of the REST JSON webservices developed for TrakCare.

These webservices allow users to access TrakCare data from outside of the software, mainly through external apps.

Hello,

I need to run some clean up routine in the background so loss of my terminal session won't stop the process.

I found the JOB command in the documentation.
JOB | ObjectScript Reference | InterSystems IRIS Data Platform 2022.1
When I try it, it doesn't seem to be doing much. I also expected this to become visible in the Background Tasks but that doesn't happen either.

Probably I am missing something.

This is the command I am running:
JOB ##class(HIHLib.Support.GetHL7MessageStat).ISBListingQuery("2017-01-01","2017-02-01",0,"WAHISCL",-1,0)::10

The same command without the ::10 has the same effect.

Hi All,

Can you help me how to extract SQL table data into a text file and generate the text file in a particular file path 

Thanks,

Is it possible to use integer with a higher precision so that something like this works:

ClassMethod BigNumbers()
{
    Set bigInt1 = 9223372036854775807Set bigInt2 = 9223372036854775808W !,bigInt1
    W !,bigInt2

    Set bigInt3 = 9223372036854775807123456789W !,(bigInt3 # 2)
}

9223372036854775807
9223372036854775810   // should be 9223372036854775808
0                     // should be 1

The docs say ". However, with extremely large numbers (larger than 9223372036854775807E127) it is not always possible to convert a numeric string to a Decimal value.

Thank you.

Is it possible to access (read, write) to an external Oracle database via Cache SQL Gateway using JDBC in Cache Object Script?  I am currently using ODBC successfully but wanted to see if JDBC was an option too.  If it is possible, does anyone have a basic Object Script example(s) that I can review?

Thanks!

We are looking for a 3rd party application that can scan our IRIS based Cache Object Script code for vulnerabilities or coding weaknesses.  There are many, many applications/vendors out there that do code scanning but none seem to support Cache Object Script or scanning the IRIS environment.   If anyone is aware of a company/product that can scan our code / IRIS environment, I would love to hear about it.

Thanks in advance for the help.

Hi, I am passing an EDIFACT file from a service to an operation using the super class. I would like to prepopulate the 'Source' variable with some information, but I’m not sure how to access this variable.

Any pointers much 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

Hi,

I am receiving a JSON File as Stream container Using  pRequest As Ens.StreamContainer and output as  Output pResponse As %Persistent in a Custom Business Operation 

Please find the code below

Method OnMessage(pRequest As Ens.StreamContainer, Output pResponse As %Persistent) As %Status
{
    Set tFilename=..Adapter.CreateFilename(##class(%File).GetFilename(pRequest.OriginalFilename),..Filename)
    Set tSC=..Adapter.PutStream(tFilename, pRequest.Stream)
    Quit tSC
}

Question:How can i extract name,DOB,SSN from the pRequest and save the same values in SQL persistant

I am trying to use the IRIS connection to connect from our LIS to Health Connect (ENSEMBLE) directly.  You can do this in the same namespace using this:

I ##class(Ens.Director).CreateBusinessService(Ensemble Service Name,.theService)
I theService.ProcessInput(TRAN,.response)

I would like to be able to do the same thing across servers using IRIS connection.  I have the following connection:

                set connection = ##class(%Net.DB.DataSource).CreateConnection(host, port, namespace, user, pwd)
                if 'connection.
