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!

This is a lesson learned, which I would like to share with community.  


Recently I ran into an issue, where I was using %ConstructClone and it kept cloning extra records, which were not needed.  The record for which I was trying to run a clone had many-to-one relationships.  

The solution to this issue was using param -1.  If you run %ConstructClone(-1) it will not clone relationships, but rather just clone single oref as desired in this case.


I hope this information helps someone who is working with similar records.

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 am working on a BPL to take data from a MS SQL database and create an HL7 Materials Message for our EMR.  I have done this plenty of times in the past however I am running into an error.

"Remote Gateway Error: JDBC Gateway SP execute(0) error 0: Access to the remote server is denied because no login-mapping exists."

What is confusing is that this BPL doesn't differ from any of my other BPLs in connecting to MS SQL Server. I know I am missing something..

$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

I've been trying to figure out how to use an ObjectScript class to search other classes for specific strings.  To be very specific, I want to be able to search business rules to see if a particular DTL is in the rule.  We have some orphaned DTL's in our Ensemble productions and I want to make sure that they're not being used.

 

Thanks.

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!

I have a case where I have an external table that lives out in MS SQL. Using Ensemble Security functions has anyone created a csp or cls page that acts like a portal to allow users to Update a multidimensional table without knowing SQL? I could clone the EnsPortal.LookupSettings but that was made for LUT which are only 2 columns.

 

 

I know its a long shot but trying to see if there was anything off the shelf that I can use to help meet the requirements of this project.

Hi All,

I am planning on doing some maintenance in 2020, I was wondering if it is possible to run a query to get a log on when a DTL and/or Business Rules was called in HEALTHSHARE, the idea behind this is to do some cleaning and remove some clutter.

Your help or ideas are highly appreciated.

Please find the code writing to the csv given below.

Hi Developers!

Often when we develop some library, tool, package, whatever on InterSystems ObjectScript we have a question, how we deploy this package on the target machine?

Also, we often expect that some other libraries already installed, so our package depends on them, and often on some particular version of it.

When you code on javascript, python, etc the role of packages deployment with dependency management takes package manager.

So, I'm pleased to announce that InterSystems ObjectScript Package Manager available!

Hello team,

I am trying to do a basic read file of HL7 messages. Need to count how many FT1 segments are there in each file and how many messages are in each file.

Any help will be appreciated. I have the stream object.

Just need to loop through the stream and get the info in some way.

Any help will be appreciated.

Thanks,

Jimmy Christian.

Hi everyone,

I've encountered this annoying issue so many times before, if any one also encounter this issue, please share here if you have any solution.

So, I've been working on a web service project using HealthShare 2015. Sometimes I have to set a debug target to a csp file to debug it. If I pause the debug process about 3 minutes above or so (to examine an object, variable, etc..) the studio will hang.

Hi Developers!

Often we need to use relatively small arrays with constants, static arrays in algorithms, etc where we need to do something with each element of an array. There are several ways to deal with it in ObjectSctipt. 

Previously I used to use globals, locals, PPG for this but not so long time ago figured out that %List is a way too handy.

Indeed, suppose we have an array of months and need to set up and use it in our code.

Hello, InterSystems community!

Lately, you have probably heard of the new InterSystems Package Manager  - ZPM. If you're familiar with it or with such package managers as NPM, Dep, pip/PyPI, etc. or just know what is it all about -- this question is for you! The question I want to arise is actually a system design question, or, in other words, "how should ZPM implement it".
