Hi Community,

I'm pleased to announce DEVBOX, the code anywhere IDE for IRIS.

Please watch the video and let me know what you think. Would you use it?

All the best,
Sean.

I want to embed the DTL editor in a third party web application.

If I open up the DTL editor then the full management portal banner is displayed.

http://localhost:52773/csp/healthshare/user/EnsPortal.DTLEditor.zen?DT=Foo.NewDTL1.dtl

If I open the same DTL in studio then I get just the editor, the banner is not displayed.

The DTLEditor page has the property studioMode that controls the banner display, but its not obvious how this is set.

In this article, we will explore the development of an IRIS client for consuming RESTful API services that have been developed to the OData API standard.

We will be exploring a number of built-in IRIS libraries for making HTTP requests, reading and writing to JSON payloads, and seeing how we can use them in combination to build a generic client adaptor for OData. We will also explore the new JSON adapter for deserializing JSON into persistent objects.

Hi Community,

I'm looking for a new contract with immediate availability.

I have 20 years experience with InterSystems technologies in areas such as Healthcare integration and single page web development.

I can work almost anywhere in the UK as well as remote work from my office in Exeter.

If you know of any opportunities or could pass on my LinkedIn details to anyone that might be looking then it would be very much appreciated.

I've been looking at the idea of developing a Time Travel Debugger utility.

It would take a debug target and have a few options such as stack depth and disclude system code.

The debugger would either be started from an external tool, or triggered from a line of code inserted into a method that I want to record.

The debugger would execute the code from start to end and record the full stack on each step to the configured depth.

It was mentioned in an earlier version of the IRIS documentation that IRIS and Cache should not be installed on the same physical server (port clashes?).

I can't see this warning in the current version of the documentation.

Could someone clarify if this has been resolved in the latest release of IRIS?

Question

Detecting Source Code Change?

Is there a responsive way to detect a source code change without using a source control hook?

Update

I have my own custom unit test tool which has lots of extra functions that I find useful such as Asserting HL7 Transformers and REST targets.

I have a studio hook that will send an event signal to my test runner that will automatically re-run a specific test class or test suite, for which I have a test runner viewing page that updates with the results.

I can directly order over a MultiDimensional property, e.g.

set key=$order(obj.prop(key))

However I have a generic method that has to use the $property method, if I know the keys then I can just fetch a value with...

set value=$property(obj,"prop","key")

But if I don't know the keys then I am not aware of a solution to do this, e.g.

set key=$order($property(obj,"prop",key))

will not work.

If your looking to develop a Node.JS to Caché library then you might want to consider using a pure TCP connection with a custom message transport protocol. This bypasses the native Caché connector libraries that can get stale with a new release.

Node.JS is very good at non blocking code development, so building a performant solution isn't that complex.

Has anyone tried adding syntax highlighting to GitHub for Caché CLS files?

Looking at the list of supported languages and extensions...

https://github.com/github/linguist/blob/master/lib/linguist/languages.yml

It looks like Mumps is supported, and there is also an existing language with a .cls extension, which would account for why I see some very odd highlighting going on with some of my code.

There is a page on contributing a new language here...

Runtime type detection

SOLVED

tl;dr how can you tell if a number is really a string

The original question has been updated/improved.

Equality comparisons on floating point numbers will produce different results...

"1.1"=1.1 //is true!

"0.1"=0.1 //is not true :(

This second comparison can be fixed with...

+"0.1"=+0.1 // is true!

If you want to dynamically serve images as a property of JSON then there is no perfect encoding solution. One method used frequently is to Base64 encode the image. Whilst there are some negatives to doing this, such as data inflation, there are some positives to working with Base64 images inside the browser.

Let's say you have an image placeholder on a web page...

tl;dr I have discovered that using $THIS in a very specific way will make persistent objects go stale.

I found that it only happens when using $get on an array that contains the OID reference of $THIS. I assume that this is an unwanted feature and have raised a WRC. The problem can be recreated following the steps below, I have also posted the workaround that I am currently testing and looks to be working fine.

1. Create a persistent class...
