Hi Community!
With this release, we've introduced the support of companies on Open Exchange.
See the details below.
Hi Community!

New features:
- Open Exchange promo block
- Open Exchange button in Article
- Github and LinkedIn profiles for a member
Plus we solved a few annoying bugs and possibly introduced some new)
See the details below.
Hi guys!
Portrait of Madame X, Gustave Caillebotte.
One of the features I like in InterSystems ObjectScript is how you can process array transformations in a specific method or a function.
Usually when we say "process an array" we assume a very straightforward algorithm which loops through an array and does something with its entries upon a certain rule.
The trick is how you transfer an array to work with into a function.
One of the nice approaches on how to pass the information about an array is using $Name and Indirection operator.
Below you can find a very simple example which illustrates the thing.
Hi Community!
This is the update on what are the new applications submitted on OpenExchange in March 2019
New Applications
isc-tar published by @Dmitry Maslennikov
Compact files as TAR or Extract files from TAR files
Light weight EXCEL download v.1.0 published by @Robert Cemper
This is the working example of a light weight export to EXCEL based on data in SAMPLES namespace. Good old CSP is well equipped to produce HTML tables accepted from EXCEL as input. With modern Browsers you don't even need and tags. So the required code around your SQL result set is really slim. And you are free to add any formatting you need either by HTML or in SQL.
PythonGateway v.0.7 published by @Eduard Lebedyuk
Python Gateway for InterSystems Data Platforms.
Adopted Bitmaps v.1.0 published by @Robert Cemper
This is a running example of the Bitmap Adoption
WebSockets Tutorial v.1.0 published by @Lily Taub
A short tutorial on WebSockets in InterSystems IRIS 2018.1+ and Caché 2016.2+
Sync Data with DSTIME v.1.0.0 published by @Robert Cemper
Other Sync-Tools just work from Caché/IRIS to Caché/IRIS. Synchronizing your data to some external DB you requires some other solution. DSTIME can do it.
HL7 and SMS Interoperability Demo v.1.3 published by @Amir Samary
This demo shows how easy it is to integrate an Electronic Medical Record system that is sending HL7 messages with AWS.

Hi Community!
I think everyone keeps the source code of the project in the repository nowadays: Github, GitLab, bitbucket, etc. Same for InterSystems IRIS projects check any on Open Exchange.
What do we do every time when start or continue working with a certain repository with InterSystems Data Platform?
We need a local InterSystems IRIS machine, have the environment for the project set up and the source code imported.
So every developer performs the following:
- Check out the code from repo
- Install/Run local IRIS installation
- Create a new namespace/database for a project
- Import the code into this new namespace
- Setup all the rest environment
- Start/continue coding the project
If you dockerize your repository this steps line could be shortened to this 3 steps:
- Check out the code from repo
- Run docker-compose build
- Start/continue coding the project
Profit - no any hands-on for 3-4-5 steps which could take minutes and bring head ache sometime.
You can dockerize (almost) any your InterSystems repo with a few following steps. Let’s go!
Hi Community!
How can I enable IRIS Text Analytics (formerly known as iKnow) in a given Namespace programmatically?
Hi Community!
There are two general ways to execute arbitrary SQL in serverside ObjectScript code: EmbeddedSQL and ObjectScript SQL a.k.a. Dynamic SQL.
E.g. if we want to get the value of the property of instance with a certain ID using SQL we can do:
&sql(SELECT Name INTO :name FROM Sample.Person WHERE ID=1)
write nameSame result with %SQL.Statement:
set rs=##class(%SQL.Statement).%ExecDirect(,"SELECT Name as name FROM Sample.Person where ID=1")
do rs.%Next()
write rs.nameHi Community!
This is the update on what are the new applications submitted on OpenExchange in January and February 2019
This is a tiny example of how to run a server command from within Caché / Ensemble / IRIS and get back the full output as seen in any server command shell.
QEWD.js is a Node.js framework for REST APIs, interactive WebSocket and/or Ajax applications, capable of running as a monolithic application or split across MicroServices. Fully supports Cache, Ensemble and IRIS, allowing use of existing Cache ObjectScript code, Cache Objects and Cache SQL, but also allows the database to be abstracted as a persistent JSON / Document database.
With this simple Business Operation, you can easily leverage your predictive models (saved as PMML) in a Production. There's both a generic BO and a utility method that allows you to generate dedicated operation / request / response classes.
Helps to generate fake/test data for development purposes
WsockClient.csp and WsocClient.js
Web socket clients on CSP and InterSystems node.js adapter to collect end manage data transferred to the client in InterSystems IRIS or Caché
CachéQuality for VSCode by @Daniel Tamajon
IDE extension that helps you detect and fix quality issues as you write code. Like a spell checker, this extension squiggles flaws so they can be fixed before committing code. You can get it directly from the VS Code Marketplace and it will then detect new bugs and quality issues as you code (ObjectScript and JavaScript)
Hi Community!
When you run IRIS container out-of-the-box and connect to it via terminal e.g. with:
docker-compose exec iris bashYou see something like:
root@7b19f545187b:/opt/app# irissession IRIS
Node: 7b19f545187b, Instance: IRIS
Username: ***
Password: ***
USER>And you enter login and password every time.
How to programmatically setup docker-compose file to have IRIS container with OS authentication enabled? And have the following while entering the terminal:
root@7b19f545187b:/opt/app# irissession IRIS
Node: 7b19f545187b, Instance: IRIS
USER>

Hi guys!
Suppose you developed a tool, framework, library on InterSystems ObjectScript for InterSystems Data Platform, share it via Open Exchange and want people to install it.
What is the best strategy if it is a library and supposed to be called from different namespaces?
Here are the following thoughts:
1. Tool's developer should be able to use globals to read/store data the tool needs.
2. Tool's consumer should be confident, that the thing he/she installs will not harm the application's data.
3. A tool should be callable from any application's namespace.
4. Tool's installation(in general) should not request manual security changes (e.g. grant the write access to IRISLIB) and %YourClass is not an option.
5. It's easy to uninstall the tool - just delete the namespace/database (maybe delete some web-apps too).
Hi Community!
It's February and we have a new release of DC features!

Hi Community!
We try a new approach to the InterSystems Developers YouTube Videos called "Coding Talks"!
Coding Talks is a short video in which the developer demonstrates a particular feature or functionality of InterSystems Data Platforms which he/she uses to in coding. Typical format: the face on side and editor with ObjectScript.
Check this video I made by myself participating in Advent of Code 2018 and coding with InterSystems ObjectScript in VSCode.
