It's been a while (and everyone is well-rested after Advent Of Code!) so let's run another round of Code Golf.

Your task is navigating in a grid-like labyrinth in a clockwise spiral pattern. As it traverses the matrix, it collects characters, revealing a secret message.
Your challenge: find the shortest, most elegant code to decode this spiral cipher.
Input:
1. A multidimensional string array with comma separated characters (n x n)
2. Starting coordinates X and Y

Output:
The decoded message as a single string

Hi,

We are developing a .NET6 application using Iris database. We would like to use ORM for easier code maintenance.

I saw a doc about Entity Framework: https://docs.intersystems.com/iris20231/csp/docbook/DocBook.UI.Page.cls?KEY=BNET_eframe, but even it's newest Iris version, the Entity Framework is very old .NET Framework (2013) and not supported by Microsoft anymore. Are there any plans to support Entity Framework Core?

We currently have a couple of Shell scripts we have written to EnableConfigItem from a Unix (Red Hat) command line, so we can control when a Service/Operation is running via the cron in Unix. We do this by calling

:>iris session xxxxx

using _system user.

During our Security audit it was mentioned that we need to lock down some of the cache users.

VSCode interop

When we add a new class in VSCode, the name automatically is set to <Folder>.<Filename>.

Because we are doing interoperability, we remove the default and type "interop" to get assistance on creating the class. This works fine on some machines, however on others it generates:

Hello everybody,

In the documentation I read the following:

Alerts are messages generated by production components. InterSystems IRIS automatically writes the alerts to a log file and sends then to the production component named Ens.Alert. If your production does not have a component named Ens.Alert, then InterSystems IRIS writes alerts to the log file but does not send them to any component. The component named Ens.Alert can be of any class. The most frequently used classes for Ens.Alert are:

I am reading file values by position with comma-separated string and it gives me incorrect values on the below line because there is a comma within double quotes within a string.

I would like to remove any text that has quotes with object script or alternatively separate each value with pipe-delimited so that I can return position 8 as code and position 9 as a description

Hi,

I wonder if anyone could help me.

I'm used to writing Microsoft SQL database queries, but at the moment I am also trying to write reports on an IRIS database (used to be cache) in Microsoft BIDS.

My chief headache is parameters. They don't behave the "normal way" in BIDS, in that you can't rename them. Therefore, referencing them in the main code is a nightmare for me.

Say my report has two parameters. If i want to refer to both in a dataset, I have to list them in the order they are in the report and both by using a question mark, ie:

using Procedure Parameters with ODBC/JDBC

Hi,

I was struggling with a procedure that was meant to receive a string and use it as a filter, I've found that since I want the procedure to do some data transformation and return a dataset, I needed to use objectScript language.

I've created the procedure using the SQL GUI in the portal, and everything works fine when calling the procedure from the SQL GUI but not through a JDBC connection here is the call "call spPatientOS('2024-04-07T12:35:32Z')"

Hi,

I trying to find out the procedure to kill off a currently printing Cache job.

The user wants to cancel the job as they put the wrong start date. The start date was set to be generated from the default date of 1 Jan 1900.

As the start date was such a long time ago, the report generation would take a long time.

I think the printing uses this "production" on the print server:

Report.Print.Service.CachePrintService

Hey Community,

In this webinar, we’ll discuss how you can now easily integrate Apache Kafka within InterSystems IRIS data platform, including via interoperability productions and programmatically via API calls, as both a producer as well as a consumer of Apache Kafka messages:

A framework yes, but a suitable framework

How can IRIS productions be deployed more quickly and with greater peace of mind?

The aim of interoperability productions is to enable you to connect systems in order to transform and route messages between them. To connect systems, you develop, configure, deploy and manage productions that integrate several software systems.

In my previous articles, I described my Command Line Extension to NativeAPI.
Of course, this is also available for any other NativeAPI package.
So I created this example as a demo for the actual Java Contest.
<--break->
The package contains also an IRIS server in Docker for the demo
It is evident that it also works with any remote IRIS server.
You just have to provide it with my NativeAPI CommandLine Extension.

How to overload methods in ObjectScript

InterSystems FAQ rubric

The InterSystems ObjectScript language does not allow you to define methods of the same name with different arguments. It is generally classified as a programming language called a dynamic language.

In ObjectScript, you can freely control which arguments are used when executing a method, so unlike languages ​​such as Java, which are not dynamic programming languages, there is no need to strictly distinguish methods by the number of arguments at the compilation stage.
