#ObjectScript

I am working on setting up our Failover techniques as we move to a Mirror Environment with a Arbiter, 2 Failover Nodes, and a Async (DR) Node. There are some system commands that I would like to call when the Mirror moves, and I am working on a ZMIRROR routine for that, but I also wanted to create an additional step if we wanted to manually shutdown and for the Mirror to move. So I was looking at using ZSTOP to call a couple of different items while shutting down, while the documentation has an example a couple of questions come to mind about using ZSTOP.

I'm wondering how I would go about adding headers to a csv file which has already been created. I am unfamiliar with ObjectScript. 

For example if I were to use R, I would simply write..

test <- read.csv("file/path/example/Extract.csv", header=FALSE)
colnames(test) <- c("A","B","C","D","E")

I do not have embedded Python installed either as I would know how to do it in that also.

How could I mirror this in ObjectScript please?

My current create file method:

Hi,
is there a way to know where IRIS or CACHE current instance is installed from objectscript?

Something like "iris list"

It will be easy to make a $ZF, iris qlist, and get the info, but i hope that there's something less complex than that.

Thanks

Is there a way to escape a comma in a comma delimited list? (ObjectScript)

Example: In("Connected, Connected, but issues, Not Connected")

(How) can I escape the comma in the 2nd value?

Thanks,

The following code snippet uses GZIP to compress/decompress a file. Choose a file by specifying a file path in the "filename" variable.

Class objectscript.GZIP Extends %RegisteredObject
{
	classmethod test() {
		//Export Global(s) uncompressed
		set filename="C:\Temp\myglobal.xml"
		do $System.OBJ.Export("^oddEXTR.gbl",filename)
		//Open exported Globals
		set uncompressed = ##class(%FileBinaryStream).%New()
		set uncompressed.Filename=filename
		Set compressed = "C:\temp\mycomglobal.

At least three different ways to process errors (status codes, exceptions, SQLCODE etc is given in ObjectScript. Most systems have status, but for a range of reasons exceptions are more convenient to manage. You spend some time translating between the various techniques dealing with legacy code. For reference, I use several of these excerpts. It is hoped that they will also support others.

///Status from SQLCODE:
set st = $$$ERROR($$$SQLError, SQLCODE, $g(%msg))  //embedded SQL
set st = $$$ERROR($$$SQLError, rs.%SQLCODE, $g(rs.

Hi,

I need to add a large number of users to TrakCare.

Is there a programatically way of adding users to TrakCare using ObjectScript?
If so, can you please send me an example.

Thanks 

Over the years, I have found myself needing to create multiple HL7 messages based on a single inbound message. Usually these take the form of an order or result from a lab. Each time I have approached it, I have tried to start from scratch under the belief that the previous attempt could have been done better.

Recently, the need arose again and I was able to create a solution that I wasn't ashamed of. My main concern was that I would always either find myself getting buried in a BPL, or use ObjectScript and attempt to edit messages using the SetValueAt Method for the HL7 Message Class.

Hi all,

I might be losing my mind or do not understand how ObjectScript does string comparisons, but the following does not look right to me.

Is it really possible that you can't compare non-numerical strings other than with an equals or not equals?

Any ideas on how this can be solved?

I need to use it with some Unicode text, in Docker image. And get this error. And documentation says nothing about it.

USER>do $zf(-100, "/SHELL", "echo", "test")
test

USER>do $zf(-100, "/SHELL", "echo", "test тест")

DO $ZF(-100, "/SHELL", "echo", "test тест")
^
<TRANSLATE>

I know that it works in some Linux environments without Docker, but no idea where is the difference. 

Morning all,

I got access to the new Bing this morning and thought I would try out some things on it. Below are a series of screenshots of what I searched and the results.
Please share your experiences here too.

Hi:

I don't understand how to use this open exchange item for auto creating deleting items. I think it assumes knowledge in the steps of how to use it which i don't get. 

Added the code into dev on  SRFT.Utility.DeleteHelper.OnDeleteSuper and  SRFT.Utility.DeleteHelper.AddHelper  

current class is 

Class Messages.XML.GenericWif.fileparameters Extends (%Persistent, %XML.Adaptor)
{

Property revisionnumber As %String;

Property primarylink As Messages.XML.GenericWif.primarylink;

Property additionalindexes As Messages.XML.GenericWif.

Hi Community,

A long time ago, I create a package for a String datatype that works with Regular Expression. It is quite a simple solution.

This can work well with packages like the OpenAPI-Suite, where you can then use the "Regular Expression String" as the type for properties of the validator objects where the Swagger contained a Regular Expression.

I am proposing we start a common package of datatypes for use. The package name to use can be provided by the admins.

The old package of mine can be removed, as it is also on a very old git profile on an email I no longer have.

XData blocks in Caché classes has a MimeType property, and dcoumentation says

MimeType — The MIME type (more formally, the internet media type) of the contents of the XData block. The default is text/xml

But unfortunately I can't set any other values, such as text/html or application/javascript, because XData still expect only XML. 

So, question is, for what reasons this property was appeared?

It would be very usefull to set in this property anything other then text/xml, and Studio would highlighted it as developer expected.

Hi folks,

I am announcing a new package I have loaded on the OEX, which I am also planning on entering into the contest this month.

In a nutshell, what it offers you are the following.

• Base classes to use on Persistent (table) classes for InterSystems IRIS to keep record history  
• These classes enable the historizing of persistent class records into another persistent class when touched.  
• This provides for a full history of any record. 
• It allows for record rollback to a specific version.  
• It can automatically purge old history records.

Do you need it?

Very simple, how to debug? The settings recommended in the docs don't work. I need a convenient way to keep track of what a function returns, like in other languages, by displaying it in the console.

Hi Developers!

Suppose you have a persistent class with data and you want to have a simple Angular UI for it to view the data and make CRUD operations.

Recently @Alberto Fuentes described how to build Angular UI for your InterSystems IRIS application using RESTForms2. 

In this article, I want to tell you how you can get a simple Angular UI to CRUD and view your InterSystems IRIS class data automatically in less than 5 minutes.

Let's go!

Hello, friends who are developing IRIS. I recently participated in the InterSystems Developer Tools Contest. This time, I made a tool based on the idea described in an article I published earlier as a template for quick query of messages. Currently, you only need to establish entity classes in IRIS, Then record the message corresponding to the entity class in the specified lookup table, and all the key fields generated in the message can be inverted indexed (the concept in ElasticSearch), which is convenient for quick query. The following is the design idea of my program.

Hi all,

In the days when I was still using studio, the indentation character of choice was tab, due to misalignment of code when using non-monospaced fonts.

In VSCode when I create new class files, this defaults to 4 spaces. Where and how do I set the default indentation for ObjectScript class files?

Also, with python it should be spaces. So what is recommended when doing python script inside objectscript classes?

Thank you.

Hey Community,

Hi everyone,

I have been reading up a bit on projection. I found a reference made to %Projection.Monitor on this page.

However, I cannot find any further information on %Projeciton.Monitor. What is it? How does it work? How do you use it? What value does it add?

Thank you.

We have created a number of REST adapters that extend %CSP.REST and these have been working fine.  However, we are now facing a problem with a new one where very large XML documents are being posted.  This is the pattern we are following:

Set inMsg = %request.Content.Read()

Set tSC = ##class(Ens.Director).CreateBusinessService("Epro_ItkHttp",.tBusinessService)

Set tSC = tBusinessService.ProcessInput(inMsg, .tBusinessServiceOutput)

However, when the %request is particularly long, it is being truncated, and working with %XML.Reader then fails in the business service class.

When requesting /MDX2JSON/PivotVariables/Patients?Namespace Patients shoud be passed to a method but its not. When argument passed directly into the method it works.

Has something changed in IRIS and this syntax is deprecated, or is there a bug and the colon is ignored? What could it be?
This question is continuation from https://community.intersystems.com/node/534811

I have a system that is sending Line Breaks\Carriage Returns within the text of a field that is breaking the parsing of the message. Does anyone have a way to get around this?

here is what I receive...

Hi *,

I want to dynamically generate the arguments of a method during compile time.

'For example, I want the following method

ClassMethod DoCleverStuf() As %Status [ CodeMode = objectgenerator ]
{
    do %code.WriteLine("    Set tSC = $$$OK")
    ...
}

to look like this in the .int code.

ClassMethod DoCleverStuf(pValue1 As %Integer, pValue2 As %String) As %Status [ CodeMode = objectgenerator ]
{
    // some generated code will be here
}

Is this possible? Or alternativel;y, can I generate a whole method at compile time?

Thanks.

Hi Guys

I've been using the example code %SQL.ExportMgr taken from here (an example from the intersystems community) an am having a few problems with it.

The code I have is below, and I'm having the following problems:

• Regardless of the dateformat property I use (e.g.  Set mgr.DateFormat = 1),  date data is always exported with format in YYYY-MM-DD
• Regardless of the timeformat property I use (e.g.     Set mgr.

Hi Community,

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?

Dear Friends

Please help me to create  %ZEN.proxyObject same in below example:

Hi all,

I am trying to use some process private variables (percent variables) in Triggers.

I am referring to values from $System.Process, like the ClientIPAddress and CSPSessionID.
These do to not contain values and I suspect it is bacause of scope. I also checked, and the %session variable is not available if the change originated from a CSP request.
I know that in triggers the scope of the variables are to be kept local, that is why NEW is to be used.

Is there a way to access the Process Private Variables in Triggers or get $System.Process to return the correct values?

Thanks.

Hi All,

Hopefully  someone can help me with this case. I need to encrypt a text(querystring) with an AES265 encryption. An other vendor is decrypting this information. I have a working class in C#. I've tried to build the same in Objectscript for the encrypt part but there's a missing link somewhere.  What's the difference between the C# and Objectscript implementation?

Objectscript code (until now):

Class TEST.ENCRYPT
{

// Symmetric Keys sample to encrypt

ClassMethod DoAESCBCEncrypt() As %Status
{
	set key="pZR8qfrz7t47G+dboyJCH4NnJRrF+dJbvxq37y/cLUo="
	set iv=##class(%PopulateUtils).
