InterSystems ObjectScript is a scripting language to operate with data using any data model of InterSystems Data Platform (Objects, Relational, Key-Value, Document, Globals) and to develop business logic for serverside applications on InterSystems Data Platform.
I hereby announce the creation of an IRC channel dedicated to Caché development:
* network: FreeNode (connect to server: irc.freenode.net)
* channel: ##cos (yes, two hashes).
Topic is anything related to Caché development in spite of the name (and the fact that of Caché development I only really know about COS anyway), so sorry in advance for the restrictive channel name :)
Waiting for you here! (my nick is idletask on freenode)
Twilio is a great tool for programmatically initiating and managing phone calls. In this example we'll go over basic account setup, create a Cache Class to manage our interaction with the Twilio API, and initiate a phone call from the Cache Terminal.
The full Class used in this example is available on GitHub as well.
I am currently looking for a Cache ObjectScript Developer. Please see job description below. If you are interested please send an email to paul.lilienfeld@libertyits.com
If you create your own Language Extensions to Object you mostly have to find the proper %ZLANGC00 or %ZLANGV00 or %ZLANGF00 and add the extensions manually. A few utilities do it already automatically (ZPM, ZME, ..) This utility allows you to add your extensions programmatically. (eg. at first run, or during installation) I found this quite useful for my Docker-based demos as it all happens at the start time.
Only a few days to go until the Global Summit! George James Software will be on hand to talk about any projects you may have on the horizon, such as application development, data and platform migration, system integration, training, and support – we can work with you to find practical and maintainable solutions that support the growing needs of your organization.
We're also running a User Group Session on Wednesday, July 22nd at 12pm. It's a great opportunity to find out more about our tools and ask us (and current users!) any questions.
Intersystems is a fascinating yet niche marketed.
We are using it, but we struggle to find good developers to join us to work on Caché or Ensemble products.
Who is interested into joining us? the job will be in Geneva, Switzerland!
How Tax Service, OpenStreetMap, and InterSystems IRIS could help developers get clean addresses
Pieter Brueghel the Younger, Paying the Tax (The Tax Collector), 1640
In my previous article, we just skimmed the surface of objects. Let's continue our reconnaissance. Today's topic is a tough one. It's not quite BIG DATA, but it's still the data not easy to work with: we're talking about fairly large amounts of data. It won't all fit into RAM at once, and some of it won't even fit on the drive (not due to lack of space, but because there's a lot of junk). The name of our subject is FIAS DB: the Federal Information Address System database - the databases of addresses in Russia. The archive is 5.5 GB. And it's a compressed XML file. After extraction, it will be a full 53 GB (set aside 110 GB for extraction). And when you start to parse and convert it, that 110 GB won't be enough. There won't be enough RAM either.
Suppose you have a Github repository with ObjectScript classes but without a Docker environment.
Recently I published a repository with a set of files that form a universal Docker and VSCode environment to let you either import and run your repository in InterSystems IRIS Community Edition on Docker or turn your repository into Docker and VSCode environment for InterSystems IRIS Community Edition.
So in one sentence:
Unpack these files in your folder and you have the Docker and VSCode environment for your InterSystems IRIS ObjectScript application!
This is a coding example working on IRIS 2020.2
It is also NOT serviced by InterSystems Support !
The demo is based on the raw class descriptions. The data classes used are Address, Person, Employee, Company For a more attractive demo, a JSONtoString method by ID was added.
Recently, I needed to create templates for newsletters. I couldn't find any tools, so I decided to use the CSP (Caché Server Pages) to build the templates.
Let's figure out how to make a newsletter similar to Weekly OEX Digest.
I will give you some additional information on my first embedded Python package. it is written as a mix of python and ObjectScript to take the best of both worlds.
I'm pleased to announce the release of version 1.4.4 of the VS Code extension, which contains the following enhancements and bug fixes. Links will take you to the GitHub issue being addressed. As always, if you already have the extension installed, VS Code should automatically update your extension. If you're a new user, use these instructions to get started.
Often when we install a code package we want to make some post-install settings, e.g. call to a method, set up a configuration file.
This article describes how to do this with the ObjectScript Package Manager.
To make any post-install calls you need to add <Invoke> elements into <Invokes> tag to the module.xml. Each <Invoke> element can have nested <Arg> elements if you want to pass params to the method:
Though the access is quite comfortable (in traditional COS sense) there are 2 main restrictions that hurt:
#1) It is not saved to disk unless your application includes code to save it specifically. #2) It cannot be stored in or exposed through SQL tables there are some more I'll show how to overcome these limits
This is a coding example working on IRIS 2020.1 and on Caché 2018.1.3
It will not be kept in sync with new versions
It is also NOT serviced by InterSystems Support !
Every now and then you may encounter a situation where for various reasons ODBC is the only option to access a remote system. Which is sufficient as long as you need to examine or change tables. But you can't directly execute some commands or change some Global.
Special thanks @Anna Golitsyna for inspiring me to publish this.
