#ObjectScript

Hi Developers

As you know it's very easy to publish a package to the Developers Community registry.

But how to test it before publishing? How to be sure that everything you introduced into module.xml is installed properly?

See the step-by-step instruction below!

Now the Classes/Rutines/DeepSee files will be automatically exported to the working directory after saving or compiling and files will be automatically deleted .

Installation

To install isc-dev , you just need to download and import the file isc-dev.xml from last release.
Some ways to import isc-dev .xml file:

• Go to Management Portal -> System Explorer -> Classes -> Import and select the XML file.
• Drag the file over Studio.
• Terminal command:

NS>do $system.OBJ.Load("yourpath/isc-dev.xml","ck")

• Get it from Package Manager Client:

NS>zpm
zpm: NS>install isc-dev

How to enable this feature:

• After importing the class in the target namespace, run the following method to set up the working directory:

NS>do ##class(dev.code).workdir("/path/to/your/working/directory/src/")

• Go to Management Portal -> System Administration -> Configuration -> Additional Settings -> Source Control.
• Select the target namespace and set the dev.FileManExtension class as the main one and save it.
• Try to create a new class in the studio and save/compile it
• Enjoy!

Hi Developers!

Many of you publish your InterSystems ObjectScript libraries on Open Exchange and Github.

But what do you do to ease the usage and collaboration to your project for developers?

In this article, I want to introduce the way how to introduce an easy way to launch and contribute to any ObjectScript project just by copying a standard set of files to your repository.

Let's go!

Hi Developers!

Another way to start using InterSystems ObjectScript Package Manager is to use prebuilt container images of InterSystems IRIS Community Edition and InterSystems IRIS for Health Community Edition.

We deploy this IRIS images on DockerHub and you can run it with the following command:

docker run --rm -p 52773:52773 --init --name my-iris -d intersystemsdc/iris-community:2019.4.0.383.0-zpm

Launch a terminal with:

docker exec -it my-iris iris session IRIS

And install zpm-module as:

USER>zpm 

zpm: USER>install objectscript-math

[objectscript-math] Reload START

[objectscript-math] Reload SUCCESS

[objectscript-math] Module object refreshed.

[objectscript-math] Validate START

[objectscript-math] Validate SUCCESS

[objectscript-math] Compile START

[objectscript-math] Compile SUCCESS

[objectscript-math] Activate START

[objectscript-math] Configure START

[objectscript-math] Configure SUCCESS

[objectscript-math] Activate SUCCESS

zpm: USER>

And use same commands for InterSystems IRIS for Health using the tag: intersystemsdc/irishealth-community:2019.4.0.383.0-zpm

The images are being published on IRIS Community Edition and IRIS Community Edition for Health repositories of Docker Hub.

We will update tags with every new release of IRIS and ZPM.

Happy coding!

When do implicit assumptions in code and arithmetic operators pose a real danger, and how can this danger be overcome?

Hi Developers!

Recently we released the updated version 0.1.3 of ObjectScript Package Manager (ZPM) which comes with the support of simplified ObjectScript sources folder structure.

What 'simplified' does mean?

Before 0.1.3 ZPM expected the following structure:

/src

---/cls  - for ObjectScript classes

---/cls/package_name/class_name.cls

---/cls/package_name/class_name2.cls

---/mac - or Mac ObjectScript routines

---/mac/package_name/mac_routine.mac

---/mac/package_name/mac_routine2.mac

---/inc - for ObjectScript macro include files.

---/inc/package_name/include_file.inc

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:

I've been having a blast with the Advent of Code puzzles this year - though I'll be heading into a busy span of time with family soon and will probably drop off toward the end. (At least, that's what always seems to happen - it's a good thing, though!)

$LIST string format and %DynamicArray and %DynamicObject classes

IRIS, and previously Cache, contain several different ways to create a sequence containing a mixture of data values. A data sequence that has been available for many years is the $LIST string. Another more recent data sequence is the %DynamicArray class, which along with the %DynamicObject class, is part of the IRIS support for JSON string representation. These two sequences involve very different tradeoffs.

$LIST String Format

At least three different ways to process errors (status codes, exceptions, SQLCODE etc is given in ObjectScript. Most systems have status, but for a range of reasons exceptions are more convenient to manage. You spend some time translating between the various techniques dealing with legacy code. For reference, I use several of these excerpts. It is hoped that they will also support others.

Hello everyone!

Recently I search how to convert Cyrillic to Latin with Cache Object Script, but didn't find anything and decided to write ourselves,

So here code:
