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:

  1. Check out the code from repo
  2. Install/Run local IRIS installation
  3. Create a new namespace/database for a project
  4. Import the code into this new namespace
  5. Setup all the rest environment
  6. Start/continue coding the project 

If you dockerize your repository this steps line could be shortened to this 3 steps:

  1. Check out the code from repo
  2. Run docker-compose build 
  3. 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!

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 name

Same 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.name

Hi Community!

This is the update on what are the new applications submitted on OpenExchange in January and February 2019

CPIPE

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

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.

PMML-Business-Operation

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.

COSFaker 

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 bash

You 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>
