Breaking a string into words

Is there any ObjectScript or a basic function that takes a string and separates it into words + punctuation/spaces array/list? Just not to reinvent the wheel. Say, process "It is a test, after all" into "It", space, "is", space, "a", space, "test", ", ", "after", space, "all". Or something to that effect.

Caution with Mixing OO and SQL

Mixing Object syntax with SQL is one of the nice features in Object Script. But in one case, it gave strange results, so I decided to isolate the case and describe it here.

Let's say you need to write a classmethod that updates a single property on disk. Usually, i would write that using SQL like this :

I'm pleased to announce the release of version 1.4.4 of the VS Code extension, which contains the following enhancements and bug fixes. Links will take you to the GitHub issue being addressed. As always, if you already have the extension installed, VS Code should automatically update your extension. If you're a new user, use these instructions to get started.

This example demonstrates the difference you may experience when you write to
Gllobals directly from Embedded Python compared to native ObjectScript.

To make this demo useful I start 2 background jobs that simply write sequentially
to a dedicated global. A common control method signals for a synchronous start.
Similar a common stop & view interrupts data feeding.

That's the principle process:

Hi folks!

I'm curious if it is possible to change the class method to another class?

I call a method of a system class to generate another class. But there is a bug/feature in a library class, so I need to tweak a bit the generated method, e.g. add additional parameter and change the line to "if" the parameter.

I hope to do this programmatically after class generation and change the code in a way I like.

What are the options?

Hi, Community!

Open Exchange (OEX) is getting more and more popular and more and more developers consider publishing their apps in the public package manager registry.

This is really great!

So the topic of thoughtful naming convention is getting more important and even critical. Let's discuss?

Hi developers,

We have just published an update to the Deltanji version control extension for Visual Studio Code.

When used in certain Deltanji workflows, triggering an automatic checkout on first keystroke could result in the developer working on an outdated copy of the code and only being notified of this later when saving their changes. In order to prevent this from happening checkout now reloads the document immediately.

Error messaging has been improved in two areas - when attempting to cancel code that is not checked out, and when trying to register new code onto a withdraw system.

We have also improved interoperability between the Deltanji extension and the InterSystems ObjectScript one, as well as its handling of multi-component objects.

If you're already a user of Deltanji then your extension with automatically update. You can find out more information on Deltanji and the latest release here.

Announcing gj :: locate. A simple extension for VS Code that will help you get to the source of your errors.

In VS Code, using either the Serenji extension or the basic InterSystems objectscript extension, this small add-on will open the appropriate class or routine and position you at the exact line where an error occurred.

No more tedious counting of lines to find <UNDEFINED>zCredit+206^Ledger.Invoice.1. Instead, with gj :: locate you can get there with just a couple of clicks.

This 20 second video tells it all:

I have a quick question regarding swizzled objects.

I have an original object, say Object a, I am working with.

I set a property a.something.somethingother.somethingelse.myNewProperty to some value x.

Then at some point I am saving a and continuing to work with it. I assume here by saving a, I saved myNewProperty as well. (as it should work)

Creating and listing XData definitions

Hi InterSystems Community!

The ObjectScript language of InterSystems IRIS has the ability to extend classes using a very interesting feature called XData.

It is a section in your class that can be used to create custom definitions to be used within the class itself and also externally.

To create one or more XData definitions for your class is very easy, see the example:

Hi Devs!

A few months ago I raised a discussion on the naming convention for ZPM modules.

And you free to put your name or your organization name for the packages you want to have your personal or company's brand.

But if you contribute to community, we suggested to have "community." package for all such libraries.

But the name is too long.
