1.About this article

Just like Caché pattern matching, Regular Expressions can be used in Caché to identify patterns in text data – only with a much higher expressive power. This article provides a brief introduction into Regular Expressions and what you can do with it in Caché. The information provided herein is based on various sources, most notably the book “Mastering Regular Expressions” by Jeffrey Friedl and of course the Caché online documentation. The article is not intended to discuss all the possibilities and details of regular expressions. Please refer to the information sources listed in chapter 5 if you would like to learn more. If you prefer to read off-line you can also download the PDF version of this article.

Intro

 

Please note, this article is considered deprecated, check out the new revision over here: https://community.intersystems.com/post/tutorial-websockets

The goal of this post is to discuss working with Websockets in a Caché environment. We are going to have a quick discussion of what websockets are and then talk through an example chat application implemented on top of Websockets.

I cannot connect to Cache from node.js  

I have installed in Windows 10 the following: CACHE 2016, node.js v 4.4.7 and  express .

-  where can I get cache.node? The link in the Intersystmes documentation  http://globalsdb.org/downloads/  doesn't work. I found cache0100.node and cache0120.node  in my Cache instance's  \bin directory. But I am not sure if I can use them or not.

 - how to install cache.node ? Where do I place it exactly? 

Can anyone recommend any tutorial or code example with installation instructions?

I have been following the online Zen Quickstart Tutorial using the lastest release documentation. In addition to playing around with the styling and making a few minor functionality tweaks, I wanted to add an additional column that shows a count of the number of phone numbers for that Contact (as shown in the image below).

This article contains the tutorial document for a Global Summit academy session on Text Categorization and provides a helpful starting point to learn about Text Categorization and how iKnow can help you to implement Text Categorization models. This document was originally prepared by Kerry Kirkham and Max Vershinin and should work based on the sample data provided in the SAMPLES namespace.

I have to connect to an external database and I'd like to use the JDBC SQL Gateway.

I followed this tutorial [1] to create a JDBC SQL Gateway and after configured it works as expected, but I don't know

how use this connection into source code. Maybe these other tutorial is related [2] and [3].

I'm new to Cache and trying to follow the Using Cache Studio PDF. In section 2.4.3(Adding a Zen form) it tells you insert the following code;

<button caption="Save" o select="zenPage.saveRecord();" />

Unfortunately that code fails compilation. If you try and use the tools there is no o select option nor a select or onselect option. I was wondering if anyone has used this PDF before and knows what the correct attribute should be?

Hi this is my first post, so a little about my background. I've been programming in PHP/JavaScript for about 10 years.  
I've got quite a bit of knowledge surrounding object orientated programming and know the basics.

Last year I looked into the Mirth integration engine and did some work around that.

I've now moved jobs and I'm doing some work (surprise, surprise) with Ensemble.

New to CSP and Zen.  I've been going through tutorials and have made some progress.  Using the "Contacts" tutorial as an example, I'm trying to create a "ViewContact" page.  I want this to be linkable so I'm using URI Parameters, which I understand.  However, what I'm not sure about is how to retrieve a specific record.  Should I use a SQL statement?  If so, how?
