Hi,

Thanks for your time.

Plain $ZF(-1) and $ZF(-2) calls from Cache Studio or Terminal have stopped launching the OS shell from Win10.

cmd (Windows Command Prompt) should be launched.

Configuration:

Windows 10 Anniversary Update, Ensemble 2016.2.0.585.0 Developer Edition x64

Is this common? I have enabled both %Developer role and a Cache CallOut privilege for all users that operate in this scenario.

In Terminal, W $ZF(-1) prints -1, W $ZF(-2) prints -1

In Studio, W $ZF(-1) hangs the IDE, W $ZF(-2) prints 0

Web Sockets

Hi

I am working on a project that will interact with some software called ROS (Robot Operating System). One of the development challenges we have is as follows:

ROS uses web sockets... So one connect with ws://localhost:9090 to the web socket server. It starts off as http, but then "upgrades" to web socket. It then keeps open this "tunnel" for bi-directional communication..

I need something like a HTTP Outbound adapter, but the Web Socket version of it...

Does anyone have any experience in this area?

Hi, Community!

How do you store the source files of your Caché project? What is the directories structure? What are the benefits?

I prefer the following structure:

/cls/package/subpackage/class.cls

/mac/package/routine.mac

/int/package/routine.int

/inc/macro.inc

/dfi/folder/sample.pivot.dfi

Example

Benefits:

  • folders are packages.
  • easy to understand what type of sources are in the project.

What is your approach?

Dynamic SQL to Dynamic Object

Hello community! I have to work with queries using all kinds of methods like embedded sql and class queries. But my favorite is dynamic sql, simply because of how easy it is to manipulate them at runtime. The downside to writing a lot of these is the maintenance of the code and interacting with the output in a meaningful way.

Standardizing Error Logging

I have been tasked with creating a class that will handle error logging in a consistent manor for an application I am working on. The need is to have all variables in the calling method logged along with some other information.

The example given was zwrite which is exactly what I need, however, I somehow need to capture the output of ZW and put it into a database table. Any easy way to capture this data? I was able to dump ZW to a file, but that is not ideal.

Any help is appreciated!

Making the most of $Query

I ran into an interesting ObjectScript use case today with a general solution that I wanted to share.

Use case:

I have a JSON array (specifically, in my case, an array of issues from Jira) that I want to aggregate over a few fields - say, category, priority, and issue type. I then want to flatten the aggregates into a simple list with the total for each of the groups. Of course, for the aggregation, it makes sense to use a local array in the form:

agg(category, priority, type) = total

Such that for each record in the input array I can just:

An interesting pattern around unique indices came up recently (in internal discussion re: isc.rest) and I'd like to highlight it for the community.

As a motivating use case: suppose you have a class representing a tree, where each node also has a name, and we want nodes to be unique by name and parent node. We want each root node to have a unique name too. A natural implementation would be:

I'm pleased to announce the latest version of extensions for ObjectScript. Just a month has gone since my latest update, and I already have something new to show.

Important. In this version connection to the server will be disabled by default. You have to activate connection through the settings:"objectscript.conn.active" = true.

I have the following problem:

  • There are several classes with method generators, which needs to be compiled during every compilation
  • I have "ckub" qualifiers enabled in studio
  • I don't want to remove "u" qualifier because I need it very much in another namespaces

So how do I force classes with method generators to recompile when "u" qualifier is present?

Hi all,

set statement = ##class(%ResultSet).%New("some_class:query_method"). // here query method is empty and with rowspec some columname

statement.Execute(param1)

I want to fetch data type of column value returned from above. eg - Name - VARCHAR, amount - INTEGER etc.
How can I get it. Or if not possible directly. Is there any other way to validate or get datatype of values returned. Line we have type() in python3

Python has become the most used programming language in the world (source: https://www.tiobe.com/tiobe-index/) and SQL continues to lead the way as a database language. Wouldn't it be great for Python and SQL to work together to deliver new functionality that SQL alone cannot? After all, Python has more than 380,000 published libraries (source: https://pypi.org/) with very interesting capabilities to extend your SQL queries within Python.

Is this available anywhere (for Health Connect)? I've found a few presentations but they are aimed at entry level.

We're looking at supporting more and more FHIR, REST plus OAuth interfaces in future. I've built some of this into older versions of HealthShare and Ensemble but it's desirable to move to supported versions.

We would be using Healthshare as a facade to other systems.

I was searching for the most simple way to connect from visual studio code to my local instance via terminal without having to change any window.

I know this can also be achieved via telnet but seems a bit overhead if you're in your local machine.

For me the simplest sollution is to open a terminal window in VS Code, navigate to the /bin folder of your instance installation and run .\csession.exe INSTANCENAME

For simplicity you can just include your /bin folder in your path so you don't even need to navigate there
