#ObjectScript

16

InterSystems ObjectScript is a scripting language to operate with data using any data model of InterSystems Data Platform (Objects, Relational, Key-Value, Document, Globals) and to develop business logic for serverside applications on InterSystems Data Platform.

Documentation.

Hi Community,

A long time ago, I create a package for a String datatype that works with Regular Expression. It is quite a simple solution.

This can work well with packages like the OpenAPI-Suite, where you can then use the "Regular Expression String" as the type for properties of the validator objects where the Swagger contained a Regular Expression.

I am proposing we start a common package of datatypes for use. The package name to use can be provided by the admins.

I'm trying to read the response to a long (indefinitely) running HTTP response with Transfer-Encoding: chunked. Ideally I'd be able to read the individual chunks from the response and do something with them as they arrive rather than needing to wait for the response to finish (because it never will) - ultimately I'm thinking to wrap these back up over a WebSocket connection which seems cleaner from an API perspective.

So far it looks like my options are:

I have the following method call (have included html and css as well). when I debug the code in a browser, JavaScript seems to work fine. Loading image is coming up, table is getting hidden. But when I close the debug and just load the page and run it, loading image is not coming up, neither the table is hidden. Not sure what is going on? I need help to understand what I am doing wrong?

<style type="text/css">

#loading {width: 100%;height: 100%;top: 0px;left: 0px;position: fixed;display: block; z-index: 99}

Macros in the InterSystems Caché

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.

With help from others here I had developed some code to take a Base64 PDF within a OBX.5 and save it locally to the file structure on the server.

I had to make a change to the code to return me a String so I can pass the Path back into Ensemble to use it in the message. When I made this change I am getting " ERROR #5034: Invalid status code structure ("/ensemble/data/transfer/AncillaryPDF/TMSAUDIO/Apr-11-1/980512729TMSAUDIO1046784936436537800.pdf")"

Here is the code...

I am trying to pull the word count from Microsoft Word document into Cache. Is there anyway to get the values of the extended file properties without opening the word document? If I right click on a word document (Word does not need to be installed) I can see the additional properties that I want to reference however don't know how to access these without calling out to VBA or poweshell.

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

I’m excited to announce that InterSystems will be joining the open source community for InterSystems ObjectScript extension to Visual Studio Code. Early this year I posted that we were on a journey to redefine the future of our IDE strategy, and what came out of that is Visual Studio Code is the IDE that can support that future.

Is there a way to exclude specific members from a class when exporting to an XML or UDL file? Bonus question: is there a way to import from that file without overwriting those members that were excluded?

The use case is to export an interoperability production class without the ProductionDefinition XDATA. We plan to source control the production items through the Ensemble Deployment Manager, but we still need to export any custom code in the class definition itself.

Hello community!

Is there any method/property/way in Caché to obtain something like unique identifier for installed Caché system? The idea is to get the identifier that will differ on any other installation/machine/etc, but will forever remain the same for the current installation, even if $zv changes (in case of update) or any data is removed from the database.

Hi Developers!

As discussed in previous parts of Package Manager stories to turn your IRIS application into a deployable package you just need to introduce the module.xml file into the root folder of the repository and describe all the resources.

I’m pleased to introduce you to a new project template on Open Exchange which contains examples of how to make different types of resources of your InterSystems IRIS application a part of the ObjectScript package and so make the deployable ObjectSctipt package.

Let's see how you can describe your application resources using this template project as an example.

See the details below.

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:

We are running Batch job in scheduled task and the messages are picking in single session and it is not easy to trace the record.

I used the Set ..%SessionId= "" at before sending the message to BP but I see the session Id is '1' created for each message.

Is there anyother way to create new session for each message sending to BP?

Thanks,

HI *,

So last night I was doing a deployment which had a query to select from a large dataset of joined tables, to iterate through and populate data in a new table.

This was done in a classmethod using embedded SQL and the %PARALLEL keyword.
On a testing environment with the same dataset, this worked perfectly a few days earlier.

I'm wondering what the best practice is for handling %Status values within the terminal. 
1. set tSC=...
    do $SYSTEM.Status.DisplayError(tSC)
 
2. set tSC=...
   zwrite tSC

3. An alternative?

Is there a meaningful difference between the two? Should one be used over the other for any reason? Should something else be used?

Hello everyone,

Recently, I've been working on a Business Process that processes a large JSON FHIR message containing up to 50k requests in an array within the JSON.

Currently, the code imports the JSON as a dynamic object from the original message stream, obtains an iterator from it, and processes each request one at a time in a loop.
