Hi Community,

We have some exciting news! It's time for the next InterSystems technical article writing competition!

✍️ Technical Article Contest: InterSystems IRIS Tutorials ✍️

Write an article that can be considered a tutorial for InterSystems IRIS programmers of any level: beginner / middle / senior from February 19th to March 17th. We've extended the submission deadline till the 24th of March!

🎁 Prizes for everyone: A special prize for each author participating in the competition!

The purpose of this post is to raise the profile of a powerful mechanism that has long been available to us, and to open a discussion about ways in which it can be used or abused.

You can read more detail about the mechanism here. To summarize, your class definition can use the Projection keyword to reference one or more projection classes. A projection class can implement methods that get invoked at key points in the lifecycle of your class.

Caché offers a number of methods for going through a collection and doing something with its elements. The easiest method uses a while-loop and lets you fulfill the task in an imperative manner. The developer needs to take care of the iterator, jumping to the next element and checking if the loop is within the collection.

Hey Developers,

This week is a voting week for the InterSystems Multi-Model Contest! So, it's time to give your vote to the best solutions built with InterSystems IRIS.

🔥 You decide: VOTING IS HERE 🔥

I am trying to determine the write-access to a windows-directory, using the method %File.Writeable(). But, this method always returns the boolean "true", even when I have revoked the write-access of Healthshare-user in this directory.

Note:
1) When the same ensemble-service tries to write a file in this directory (which it says is "writeable"), it fails.
2) The method %File.Writeable(...) works perfectly in the case of files.

Any help is appreciated.
Thanks in advance... :-)

I want to consume external websocket api, URL looks like this:

wss://site.com/ws/v2/?&token=<token>

Checked with external tool (Simple WebSocket Client) that websocket works and I can consume the data.

In Cache the relevant functionality is offered by %IO.Socket class.

set sock = ##class(%IO.Socket).%New()
set sock.SSLConfig = "MyEmptySSLConfig"
set sock.TranslationTable="UTF8"
do sock.Open("site.com/ws/v2/?&token=<token>","443", 10,.sc)

However I get this error:

All responses are appreciated. I am new to both scripting and CACHE so please bear with me. I am setting up a nightly backup script for freezing cache then backing it up and then thawing it back out. Currently when I enter the freeze command I am getting a response of access denied even though my id has %all access. I've tried passing the userid/password as a parameter in the externalfreeze command and passing it from a file. I've used my id and lastly I used the _system id in the file. What ID should I use for this or am I passing it wrong?

I have a %Stream that I want to insert some text into the middle of. I create a new stream called pNewContentStream from the original stream, then I do a MoveTo in pNewContentStream to get to the byte position I want to insert into but when I do my Write, my pNewContentStream gets obliterated with only the text that I wrote, the original content goes away and all I'm left with is my Write text.

Hi developers!

Could you please advice what is the easiest way to download globals from a particular server?

I have the access to it, I know which globals I need to download/copy (5-7 globals per name). This is to perform then analysis in IRIS BI.

When I run the following cmd in Ubuntu 18.04

the container is created and stays running

But when I run this cmd, the container is created but exits immediately

Hi Community,

I would like to present my last package OpenAPI-Suite, this is a set of tools to generate ObjectScript code from an OpenAPI specification version 3.0. In short, these packages allow to:

• Generate server-side class. It’s pretty similar to the generated code by ^%REST but the added value is the version 3.0 support.
• Generate HTTP client classes.
• Generate client production (business services, business operation, business process, Ens.Request, Ens.Response) classes.
• A web interface to generate and download the code or generate and compile directly on the server.
• Convert specification from version 1.x, 2.x to version 3.0.

I would like to examine the contents of my OBX-5 field and not route the message if it contains alphabetic characters. I've tried various combinations of the Match and Contains functions, with no luck. Should I be using the COS ? operator or plaini regular expressions?

e.g.

OBX-5 Contains "\D"

OBX-5 Contains "?.A"

OBX-5 Contains "[A-Z]"

Does anyone NOT use a debugger? I can't remember the last time I did. It's not because I don't dislike them, I just don't need to use them. The main reason for this is because I have a certain development methodology that either produces less bugs, catches them at a unit test level, or makes tracking them down much easier.

Here are my tips...

1. Write your own COS cheat-sheet.
