#ObjectScript

I have SQLCompute with SQLComputeCode on a couple of Properties in my class.

These work fin when I insert/update via ObjectScript or SQL from the ManagementPortal.

However, if I insert (create new record) via my C# app using the Caché ODBC DLL the SQLCompute is ignored, it does not run.

Is this expected InterSystems Caché behaviour? We are on latest IRIS platform.

I'm pleased to announce the latest version of extensions for ObjectScript. Just a month has gone since my latest update, and I already have something new to show.

Important. In this version connection to the server will be disabled by default. You have to activate connection through the settings:"objectscript.conn.active" = true.

Hello Everyone,

I'm want to know, what is more common for your company to use, the abbreviation syntax or the complety name of commands, and why?

Ex. 

S VAR=10 / D FUNC^ROUTINE F 1:1:1000

Set VAR=10 / Do Func^Routine / For 1:1:1000

set var=10 / do func^routine / for 1:1:1000

Here in my company, we are familiar with the abbreviation syntax, because to spell is more faster.

Good Morning- 

I am currently looking for a Cache ObjectScript Developer. Please see job description below. If you are interested please send an email to paul.lilienfeld@libertyits.

Hi Developers!

Often I find questions on how to install IRIS, connect to IRIS from IDE, setup the environment, compile, debug, maintain the repository.

Here below possibly the shortest way to set up all the environment and start development with ObjectScript on InterSystems IRIS.

Prerequisites

Make sure you have Git, Docker, and VSCode installed

Install Docker and ObjectScript extensions into VSCode

Sign in or Create an account on Github

Here we go!

In the previous article, I have demonstrated a simple way to record data changes. At this time I have changed the "Audit Abstract Class" which is responsible for recording audit data and the data structure where the audit log will be recorded.

I have changed the data structure to a parent and child structure where there will be two tables to record the "transaction" and the "fields its values" changed on that transaction.

Take a look at the new data model:

Take a look at the code changed from "Audit Class":

I have a custom written date, setup as myDate in my application, which always behaved fine for years, and now it's acting a little weird. 

When I run SQL in Display mode the date shows as 1/10/1841 for some but not ALL rows.

When I run the same exact query in logical Mode the date shows normal format, in my case, for example 10/1/2019.  When the application is running is shows the incorrect date.  When I run the terminal session and open a ref point and ask to write a date is shows 10/1/2019, but I am expecting internal format here - 65287.   

I was wondering what is causing this issue.

Hello!  I have basic web services application that java clients connect to the cache web services.  Using the browser, the user enters in the following url.

http://localhost:57772/csp/foia/%25SOAP.WebServiceInvoke.cls?CLS=SOAPFoia.SOAPServiceFoiaWeb&OP=FoiaApp30
'

which runs a soap method called FoiaApp30.   I am not sure how to add https  security to the web service calls.  I have reviewed documentation pertaining configuring SST/TTL configuration and other information.   Can somebody please help me out on what I need to do?

GitHub Repository Template To Develop and Debug ObjectScript in InterSystems IRIS

I must be missing something. We have done encoded PDF's in the past with the Encoded PDF in OBX.5.5. When I have used this code in the past I was only working with 1 OBX, but I have a case where I am having multiple OBX's and having to loop through them and I am renumbering the outbound OBX.

<code>
<![CDATA[ // OBX]]></code>
<assign value='1' property='varOBXindex' action='set' />
<assign value='1' property='varOBX1' action='set' />
<foreach property='source.{ORCgrp(1).OBRgrp(1).OBXgrp()}' key='k1' >
<if condition='source.{ORCgrp(1).OBRgrp(1).OBXgrp(k1).

🎯 Creating REST API with InterSystems IRIS, ObjectScript and Docker

I  am reading the following code in ObjectScript:

GitHub repository
 

And there is a sentence which I am facing difficulties to understand:

    kill ^OPNLib.Game.CWLF(..World)

I know that kill removes variables, OPNLib.Game are the package and subpackage, and ..World is a property. However what does CWLF mean?

You could think that it is the class' name, but it is:

Class OPNLib.Game.ConwayLifeGame Extends %Persistent

The class name is ConwayLifeGame

Is CWLF an alias for the class name?

Hi All,

I am encountered <INVALID OREF> error in one of the components in the namespace as we are processing and generating huge files and sending them to downstream systems. One possible way we tried was to allocate more memory for the namespace in ensemble, but this kind of intermittent error still occurred only if processing the huge files. Also we tried to resend the failed message and the error would be gone. Another possible solution is to kill unused local variables to release memory space.

Hi,

I got the <INVALID OREF> error in the component and the error screenshot as follows:

​​​​​​

When I try to debug in the code, I go to the class and view other code in eclipse and find out the error method. How should I determine which line threw the error according to the error? There is the line number"+8" in zProcessRequest method. Is that the line counted from the method name or below? Looking forward to your reply. Thanks.

HI,

I am a newbie so excuse my basic questions.

I have installed Caché on Mac Os High Sierra 10.13.6 and have started the ObjectScript tutorial but I cannot open Terminal in Caché.

The instructions provided on the tutorial don't appear to be for Mac OS as there is no cube icon:

n order to begin practicing using ObjectScript, you need to start the Terminal. Click the Caché cube iconin the task bar and select Terminal from the menu. This brings up the terminal window, and you can see from the prompt that we are in the USER namespace.

Hi Everyone!

New video, recorded by @Stefan Wittmann, is already on InterSystems Developers YouTube:

SQL and Object Access

Hi Developers!

When you prepare your modules for ZPM (InterSystems Package Manager) it expects the certain directory structure for ObjectScript source files.

ObjectScript in your source folder need to be stored by types in the following subfolders. E.g. if you have the source folder named as /src the structure should be as follows:

/src

        /cls - for classes

        /inc - for include files

        /mac - for mac files

        /int - for interpretable files

        /gbl - for globals

And the ObjectScript should be in CLS (a.k.a UDL) and not in XML.

Example.

Ok!

Hi All,

I have a class method, this can be any cache expression to execute (usually a class / method and args) and and args stored in a variable, for example;

set aa = "##Class(Utils.Test).Run(1,2,3)"

do aa

I tried using $classmethod(class,method,args..), by extracting the values but sometimes there can be no arguments, or arguments such as ;

("2019-01-01","1,2,3,4")

which causes issues while running the $classmethod, (i am using $P to extract the Class, Method and args).

Is there any simpler way of doing this?

We have a case where we have 1 message coming in, but then sending two messages out to the same location. Even with FIFO sometimes the messages get out of sequence depending on what is need to be done to the message in the DTL before send. Is it possible to call sleep or Halt or write some kind of a function to put a pause in a routing rule between two sends?

I've created a scheduled task that dumps HL7 messages to flat files. It uses the OutputToLibraryStream() method of EnsLib.HL7.Message. I'd like to be able to run it on a mirror member host whether it's primary or backup.

When run against a database that's mounted read-only, it works fine. However, when I attempt to run it against a mirror backup database, I get the following error:

#5002: Cache error: <PROTECT>%LoadData+7^EnsLib.HL7.Message.1

Tracing that back to the source, I find:

Lock +(^EnsLib.H.

Hi guys!

Was coding today with InterSystems IRIS in a docker container and decided to share with you the commands you may find useful in everyday coding.

# docker-compose build

command to build a container. Remember, it is useful if you have dockerfile in the repo.

if the build is successful call the following to launch it:

# docker-compose up -d

Find IRIS management portal on:

localhost:port/csp/sys/%25CSP.Portal.Home.zen?$NAMESPACE=%25SYS

where the port is what you set in docker-compose.yml - 52775 in this case.

Run the following if you want to launch a terminal session inside IRIS container:

# docker-compose iris iris session iris

gfhj gj 


sdfdsfsdf





USER>

And run the following to shut down the container:

# docker-compose down

Troubleshooting

Is there a system function/method which can create a GUID ?

What's the best way to replace character groups?

I want not to remove character groups as $zstrip does but to replace them with whitespaces.

$translate needs explicit character list.

Effectively I want to remove any characters besides letters, numbers and a small (known) subset of punctuation characters, replacing everything else with whitespaces.

After upgrading I ran a $SYSTEM.OBJ.CompileAllNamespaces("u"). What I got in return was kind of a shock.

In reviewing errors I am seeing code being referenced but no longer applies. It is referring to stuff that might of been defined in the Context , Formal Spec ,Thread , etc.

ERROR #5373: Class 'osuwmc.CPD.DataStructures.TblPharmacyDEA', used by 'osuwmc.CPD.BusinessOperation:SelectProviderTempDEA:FormalSpec', does not exist

I am new to cache programming language . I am facing below issue . please assist.

Question: One persistent class ID column is a combination of its properties (Roll No and Marks) [ Exact: RollNo||Marks]. When i am running the query from Management portal it is displaying data in the same format and data is there. But in the code if i am making below statement, i am getting null value.

Set ExistsID=##Class(User.School).%ExistsId(RollNo_"||"_Marks)

set ID=##Class(User.School).%OpenId(RollNo_"||"_Marks)

ExistsID showing 1, but ID is always displaying as Null but data is there in class with that ID.

We have a customer that is not able to accept HL7 result messages that are missing OBX:3.1. I have been trying to create a function that could return a boolean value of 0 if the message didn't meet the expectations of the function.

ClassMethod IsValued(pHL7Msg As EnsLib.HL7.Message, pSegment As %String, pField As %String) As %Boolean
{
            #dim tSeg as EnsLib.HL7.Segment
            
            set tSegCount = pHL7Msg.

Hello,

I had an issue when using the method Exists, I noticed that if you provide a directory for this method it returns 1. This is really misleading, because sometimes the input could be a directory and the only way to predict this is to also test if the file is a directory.

I didn't tested using the Attributes method, but I supposed that this means could also be a solution for that issue. But still, I expected the Exists method to return 1 for files and 0 for directories, since there's also method called DirectoryExists already.

write ##class(%File).

Is there a way that when you run $system.OBJ.Compileall() that you can make the output written to a file instead of the screen? I am trying to capture all the errors so I can review the code and fix them before we upgrade.

Thanks

Scott
