Hey Developers,

Advent of Code 2020 is over! Thanks for participating in InterSystems ObjectScript marathon!

And now we're pleased to introduce the winners and distribute all the prizes!

Big applause goes to these winners:

@Kevin An (w/ repo)

@Fabian Haupt (w/ repo )

@Yuval Golan (w/ repo )

And here's the final InterSystems leaderboard:

Hi Community,

This post is to introduce one of my first project in COS, I created when started to learn the language and until today I'm keeping improve it.

The CosFaker(here on Github) is a pure COS library for generating fake data.

cosFaker vs Populate Utils

So why use cosFaker if caché has the populate data utility?

Hi everyone.

This is a full example how to use a %ScrollableResultSet for results pagination using %DynamicQuery:SQL and build a JSON response including page details.

Feel free to use, share, comment or improve it.

Kind Regards

In this article I would like to tell you about macros in InterSystems Caché. A macro is a symbolic name that is replaced with a set of instructions during compilation. A macro can “unfold” in various instruction sets each time it is called, depending on the parameters passed to it and activated scenarios. This can be both static code and the result of ObjectScript execution. Let's take a look at how you can use them in your application.

Hi Community

In this article, I will introduce my application irisChatGPT which is built on LangChain Framework.

First of all, let us have a brief overview of the framework.

The entire world is talking about ChatGPT and how Large Language Models(LLMs) have become so powerful and has been performing beyond expectations, giving human-like conversations. This is just the beginning of how this can be applied to every enterprise and every domain!

When creating a PRA (Privileged Routine Application; which by the way is not relevant just for Routines but also for Classes/Methods), it is important to make sure you include a new $ROLES, before calling

After many sleepless nights it's a pleasure to announce the newer, better, moderner ObjectScript compiler which implemented pretty much everything you ever wanted to have in modern ObjectScript:

• Design objective of this new compiler is to parse reasonable subset of current ObjectScript syntax which will look readable for stranger, and not scare them with 1 letter syntax. The good start for compiler was the old-good COS Guidelines from here https://github.com/intersystems-ru/cos-guidelines
• For reasons we mentioned above we do not parse 1 letter syntax. It's declared evil;
• We do not handle dotted syntax for the same reason - modern syntax with {} is proper replacement for dotted syntax blocks;

But we not only parse the modern ObjectScript syntax, we have implemented finally the long-standing request which we always dreamed about. Closures!

Introduction

In the next few weeks, my coworkers are planning to start using VSCode to code with InterSystems' products. Among the many advantages of that, I would emphasize being able to connect with other technologies, such as GitHub, with ease. Besides, VSCode also offers an extensive extensions store, where you can find many free add-ons that make coding faster and more efficient. Last but not least, to conquer the heart of every developer, it is open source.

Hi Developers!

InterSystems Online Programming Contest is over. Thank you all for participating in our IRIS Competition!

As a result - 20 great apps! And now it's time to announce the winners!

Some time ago I got a WRC case transferred where a customer asks for the availability of a raw DEFLATE compression/decompression function built-in Caché.

When we talk about DEFLATE we need to talk about Zlib as well, since Zlib is the de-facto standard free compression/decompression library developed in the mid-90s.

Zlib works on particular DEFLATE compression/decompression algorithm and the idea of encapsulation within a wrapper (gzip, zlib, etc.).

Disclaimer: This article uses Russian language and Cyrillic alphabet as examples, but is relevant for anyone who uses Caché in a non-English locale.
Please note that this article refers mostly to NLS collations, which are different than SQL collations. SQL collations (such as SQLUPPER, SQLSTRING, EXACT which means no collation, TRUNCATE, etc.) are actual functions that are explicitly applied to some values, and whose results are sometimes explicitly stored in the global subscripts. When stored in subscripts, these values would naturally follow the NLS collation in effect (“SQL and NLS Collations”).

Hi all, I have released the latest version of VSCode extension for ObjectScript already a month ago, and finally a time for the info about this new release.

So, what's new in the release:

What's new in this version

• added export setting "objectscript.export.addCategory" if enabled uses the previous behaviour, adds category folder to export folder, disabled by default
• added Server actions menu, by clicking on server info from status bar. Open Management portal, Class Reference and toggle connection.
• Class Suggestion in ##class, Extends, As, CompileAfter, DependsOn, PropertyClass
• $SYSTEM suggestion by Classes from %SYSTEM
• Import and compile folder or file by context menu in File Explorer
• Server Explorer, now possible to open any other namespace
• Macros suggestion

For details how it works now, look further.

@Ming Zhou asked a great question in https://community.intersystems.com/post/how-get-all-properties-defined-c... and the answer sums up exactly why ObjectScript is my favorite.

Is anyone in the fine community of developers who work with ISC technologies looking at Microsoft's Visual Studio Code offering?

One of Bill McCormick's recent posts about Atelier referred to Visual Studio being considered the best IDE. Granted, Code is far less of a tool than VS, and probably always will be. But it claims to be open source and cross-platform, i.e. Linux and OS X as well as Windows.
