Hi Developers!

Recently we published on Docker Hub images for InterSystems IRIS Community Edition and InterSystems IRIS Community for Health containers.

What is that?

There is a repository that publishes it, and in fact, it is the same container IRIS Community Edition containers you have on official InterSystems listing which have the pre-loaded ObjectScript Package Manager (ZPM) client.

So if you run this container with IRIS CE or IRIC CE for Health you can immediately start using ZPM and install packages from Community Registry or any others.

What does this mean for you?

It means, that anyone can deploy any of your InterSystems ObjectScript application in 3 commands:

  • run IRIS container;
  • open terminal;
  • install your application as ZPM package.

It is safe, fast and cross-platform.

It's really handy if you want to test a new interesting ZPM package and not harm any of your systems.

Suppose, you have docker-desktop installed. You can run the image, which wiil pull the latest container if you don't have it locally:

Hi Developers!

Many of you are looking for samples on how to work with InterSystems IRIS Analytics, formerly known as DeepSee.

There is a Samples BI module with Patients and Holefoods examples which is available on Github with source code. The installation steps are clear but take time.

Recently we added the option to run IRIS Community Edition containers with ObjectScript Package Manager (ZPM) on board. This simplifies the installation to the "run-one-command" step for the modules submitted to ZPM Community Registry. And thus we can benefit the Samples BI installation with ZPM.

And here is how you can run it on your laptop. Let's go!

Hi Developers!

Often when we install a code package we want to make some post-install settings, e.g. call to a method, set up a configuration file.

This article describes how to do this with the ObjectScript Package Manager.

To make any post-install calls you need to add <Invoke> elements into <Invokes> tag to the module.xml. Each <Invoke> element can have nested <Arg> elements if you want to pass params to the method:

Hi Developers!

I'm pleased to announce that ObjectScript package publishing is now generally available on Open Exchange with this November 2019 release!

If you want your ObjectScript application to be published in ObjectScript Package Manager just enable "Publish in Package Manager" option:

And send the app on approving.

Once the application is approved it will be published automatically in ObjectScript Package Manager Registry and will be available for installation via ZPM client.

See the details below.

Hi Developers!

Suppose you published your application on Open Exchange with version 1.00. And then you've added a new outstanding feature and you make a new release.

You can also make a new release of your application on Open Exchange.

Why make releases on Open Exchange?

This the way for you to highlight the new features of your application. When you publish a new release the following happens:

Release notes appear on the News page of Open Exchange

The version of your app changes

Have you ever needed a math function but could not find what you needed and ended up writing your own? Look no further! ObjectScript-Math is here to solve all your math related function needs.

ObjectScript-Math is an Open Source library for ObjectScript Math functions. It is now available on Open Exchange. This library contains a mix of new functions that are not currently available and functions that are available. The existing functions will be wrapped for use from ObjectScript-Math so that all Math functions can have a central location.

This library will continue to grow, so give it a try and give your feedback!

Don't see what you are looking for? Please feel free to submit requests for additional functions or contribute code yourself!

Portlets that use data from DeepSee


In the previous part of this series, we saw how to reference a web page that will enhance our dashboard experience. Now we will look into referencing data that is already in our cubes.

In this example, we will be referencing the controller object and we will be extracting data from it. This data will then be displayed as text in our Dashboard. In Part 5, we will show how to incorporate this data into other charting libraries.

Creating Portlets in DeepSee

What is a portlet?

The simple answer is: a custom widget. A portlet can exist by itself on a DeepSee dashboard, it can be used along side standard DeepSee widgets, or along side other portlets. The rendering of the custom widget is completely user defined. This means you can embed a web page, create a form to perform any sort of action needed based on the data on your dashboard, use third party charting libraries, or simply display data from outside of a DeepSee cube.

Hi Developers!

For those who want to participate in the Advent of Code 2019 and code with ObjectScript in IRIS, I created a very simple but handy Github Template.

Use the green button

to copy template in your own repo, clone the repo and run in the repo folder:

docker-compose up -d

you will get InterSystems IRIS 2019.4 Community Edition running with the template classes to load input data from files and Day1 solution.

This is also set up to start crafting solutions of Advent of Code 2019 and edit, compile and debug ObjectScript with VSCode addon.

Happy coding with Advent of Code 2019!

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.

Hi Developers!

Recently we announced two new challenges on Global Masters: 'Bugs Bounty' and 'Pull Requests'.

And we are getting a lot of submits to the challenges which are not the thing we are expecting there. So I hope this post will give some shine to this quest.

'Bugs Bounty'

Ok! What are we expecting from 'Bugs bounty'?

There are a lot of Open Exchange solutions that come with public open-source repositories on Github: project and repo, another project and the repo, another one and its repo, and many more on Open Exchange.

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!

Hi Developers!

Those who use Dockerfile to work with InterSystems IRIS often need to execute several lines of ObjectScript. For me, this was a game of "escaping this and that" every time just to shoot a few commands on ObjectScript to IRIS. Ideally, I'd prefer to code ObjectScript without any quotes and escaping.

Recently I found a nice "hack" on how this could be improved to exactly this state. I got this from @Dmitry.Maslennikov's repo and this lets you use Objectscript in a way as you would type it in IRIS terminal.

Here is what you have in dockerfile:

///
COPY irissession.sh /
SHELL ["/irissession.sh"]
RUN \
  do $SYSTEM.OBJ.Load("Installer.cls", "ck") \
  set sc = ##class(App.Installer).setup()
# bringing the standard shell back
SHELL ["/bin/bash", "-c"]
CMD [ "-l", "/usr/irissys/mgr/messages.log" ]
///
