ZPMshow, a helper for tired fingers

The offer of ZPM is growing daily and the short names and
acronyms of the offer are sometimes hard to understand and
also hard to type with my lazy fingers.

So I decided to have

  • a listing with the descriptions from the repository,
  • split in short junks to avoid backscroll,
  • controlled forward / backward scrolling,
  • the option to select my packages by number,
  • to install or uninstall with limited typing.

It runs with do ^zpmshow

A snapshot from the screen:

It would be interesting if there is some recommended documentation about best practices using Healthshare for interoperability.

Also, some how-tos or frequently asked questions about ObjectScript.

Or event better, if there are experienced developers who would like to share some common habits on their work with Studio / ObjectScript, which are valuable to do the developing work better.

For example, How to get the XML of a class and write it into a REST operation:

Fast JSON formatting (IRIS)

t's also an example for a customized command extension (ZZJSON) in IRIS

IRIS has a nice %JSON.Formatter class.
But for debugging it is not really handy.
see:

ZWRITE js1  
js1="{""Name"":""Cunningham,John C."",""SSN"":""294-11-9150"",""DOB"":""1933-01-08"",""Home"":{""Street"":""4249 Ash Street"",""City"":""Tampa"",""State"":""MD"",""Zip"":""30176""},""FavoriteColors"":\[""White"",""Red"",""Green""]}"

so you proceed for the most simple case

I need to set and use some context variables in a transformation (written in DTL), but the code is manually written.

When writing the same as BPL I define context variables and they are visible in transformations called by that process.

In something like this my.DTLtransform sets HL7 message fields to values in context variables:

DTL vs. ObjectScript

As I've become a little more familiar with HealthShare, I'd like to start exploring different ways of doing things. To date, the bulk of my data transformations have been using DTL; only using ObjectScript for a few operations that write to external SQL tables that were largely based on examples provided by my sales engineer.

I'm working with VS Code on Centos 8. When I install the ObjectScript extension the installation succeeds, but the InterSystems icon never appears in the left-side panel. I can change settings for the extension - set the server info, etc. No errors show-up in the VS Code debug log.

UPDATE: the same thing happens on MacOS when using VS Code 1.46.1 and InterSystems ObjectScript extension 0.8.6

Can anyone suggest next steps for me to troubleshoot? Is there another log I should check?

Hi all

Does anyone have an easy way of reading the cdata in the xml response returned buy a Webservice?

At the moment I have a XML class and then I use read.Correlate() to read through that XML bit.

However, depending on the message I have different things in the CData and I don't want to create a class for each one of these.

The API returns the cddata as KeyValueOfstringstring.
