InterSystems Caché is a multi-model DBMS and application server
Some may think it's a strange / daft idea, but just today the Raspberry Pi folks have announced that they've now sold more than 10 million of them..and counting. That's a huge potential marketplace, and a great platform for getting people to hear about Cache and try it out. Given its focus on the education sector, another great way of getting heard about.
I have a Cache classes with %TimeStamp (e.g. 2016-04-18 12:29:11) and %Date (eg. 64027) properties. And I have a javascript client app, which needs full CRUD over this properties.
But in javascript date/time are defined by ISO8601 (e.g. timestamp 2016-04-18T12:29:11Z, date 2016-04-18).
Hi, Community!
Last weekend we held the Final of InterSystems Contest on InterSystems Caché and DeepSee as a part of IT Planet Student Championship in Sochi. BTW, this year we had about 2 000 participants in InterSystems Contest.
Let's have a round of CodeGolf!
As usual the goal is to write the shortest solution for a specified problem.
Today we have one of the classics: FizzBuzz.
Write a program that prints the numbers from 1 to 100.
But for multiples of three print “Fizz” instead of the number and for the multiples of five print “Buzz”.
For numbers which are multiples of both three and five print “FizzBuzz”
After enabling archiving log functions, Oracle can get real-time change data through CDC.
Can Cache database realize such functions?
My requirement is to take incremental data from the cache database regularly every day and synchronize it to other relational databases.
Incremental data can be text files.
Hi Community!
Sometimes I meet a method which accepts 10+ parameters.
And often I need only the 8th parameter to pass. And I call the method something like:
do ##class(Some.Feature).Method(,,,,,,,"flag")And I don't like this method when I call it like this cause, you know, often I just miss the number of commas and raise some other flag I wanted.
How do you avoid this situations?
If you meet such a code, how do you call it and sure that you didn't miss the number of ","?
What is a good number of parameters in a method and f you need to pass more parameters in a method what do you do?
Hello everyone!
Does anyone know of a library that can be used to create Mock objects for Objectscript classes?
Right now, my team has been building mock objects by hand to help circumvent dependencies when writing and executing unit tests, but I always wondered if someone had ever created a Mock library like Mockito to help quicken the process.
Thanks!
Hi all!
I'm developing a mini-framework to implement annotations in Cache. I want to support two kind of annotations: metadata and method decorators. I've got stuck trying to implement the second one.
With metadata annotations I can add metadata to any kind of target. A target can be a method/classmethod, parameter, property and class.
For example:
I'm finding that in a mobile app setting, that Cache is causing the worst User Experience that I have ever seen in a mobile app - I'm just saying this hoping that someone will be able to help me out, my intent is not to criticise Intersystems.
We have a Xamarin Forms mobile app that consumes web pages that are created by Cache. The app compiles into iPhone, iPad, Android Phone, Android Tablet, UWP (Windows 10, all of phone, tablet, and desktop), as well as MacOS.
I have a classname and a property name. I want to know, when I get object value directly from a global, which property corresponds to which position in the $lb structure.
Here's what I got so far:
Hi -
I'm trying to create a method that will automatically create something I can save and use later, which will let me automate data migration from one version of a class to the next.
In Cache 2013.1.6.950.1 I have a ZEN dataGrid which works fine except if I use the mouse wheel to scroll through it.
It is my understanding that when a routine accesses a global it is temporarily stored in global memory. While the global is within global memory, any other routine would be able to readily access the global from memory and not from disk so long as the same node is being utilized.
Hi Community!
Suppose you have a working system on 8-bit Caché database and need to transfer the solution to Unicode database.
How do you manage that?
Has anyone called any outside Javascript code from inside their class files? I asked a long time ago if there was a way to manipulate an image within Cache Object Script, and since Cache doesn't have any image libraries its not really possible. However I have found Javascript to resize an image and wonder how hard it would be to mesh the two together.
Can anyone share any examples?
Thanks

Hello, guys.
I have an external file that contains data in UDL format(as in Studio, not XML) and I need to somehow overwrite my source file with that file.
I tried to use this snippet for .mac file
Hi,
Can we create a new class in the studio using any command rather then using the Menu Item Option from Menu Bar in Studio .
Requirement : Create/Draft a new class and able to extends the other classes using a command in Cache Class .
In other words , I want to Dig in the Menu Item class from which Menu bar is created in studio and option are provided Like New..., Open..., etc
Thanks,

Problem: I have a REST broker, and if I hit a code block, which does IO redirection, the REST reply becomes broken in one of the following ways:
Consider the following REST broker:
Hi.
It is easy to receive JSON representation or dynamic Array from %ListOfDataTypes:
set l=##class(%ListOfDataTypes).%New()
do l.Insert("a")
do l.Insert("b")
do l.Insert("c")
set arrStr=l.$toJSON()
zwrite arrStr
set arr=l.$compose([])
zwrite arr
How to make backward conversion? How to receive %ListOfDataTypes from dynamic Array an JSON string?

Hi,
I know you're doing a big effort to build a new IDE in Eclipse ecosystem but Visual Studio Code is a new an even better and faster tool for coding... did you have any plans to release any COS extension for it in the near future? There you can already find extensions for all current more common progrmaming languages and it would be great to have COS as one of them.
Thanks
Hello everyone,
I have discussed extensively with Andrew Cheshire, the author of the Atelier parser (which I'll be able to hack on and reuse for CachéQuality -- yay!), and while we were at it, we also discussed code coverage.
We ended up talking about the ZBREAK command and its /TRACE option.
This post is originally posted on GitHub.
This discussion is open to anyone who use or know about WebTerminal project. It is a result of a long story of the project development, testing and maintaining.
This question came on the Ensemble in Healthcare email list. It's a great question. I'm working on an answer, but am posting it here to get any other input. I'll also address the option of using %CSP.REST.
Hello everyone,
Hello community!
I am trying to set up Startup Tag^Routine field for the UnknownUser as follows:
And my simple routine is the next:
I want to determine what service (eg. %Service_Console) is used for current process.
I can probably use some workarounds, i.e.
But is there any centralised way to get current service?
I understand this is a rather broad topic (and at times involves religious sentiments) yet I would like to look at it from the Caché perspective:
I have a %Net.Request object and I want to get a full URL of the request sent (preferably after all redirects, but even full initial one would be good). For example, I have the following method:
I want to override the Get and Set methods of a class property. The class maps to a pre-existing global. The property is defined like so:
Property Invalid As %Library.Boolean;
with the property mapping to a node like ^GLOBAL(Code,"INVALID")=1
Code is a property in the same class.
The value can be 0 or 1 or the node might not exist. When it doesn't exist I want the value of the SQL field to come out as 0 (false).
I know that Cache files can be stored as XML and UDL based files. Is there any way to determine in which format the file(class, routine, dfi and so on) is stored? Because you can easily name your XML based file as class.cls and it will be perfectly valid.
I know that one way to check whether this file is in XML format is just try to parse it like
Set st = ##class(%XML.TextReader).ParseStream(contentStream)
if $$$ISERR(st) return $$$NO
else return $$$YES
However, is there a better way?
If you had to choose Angular 1 or 2 for a new web project using Caché/Ensemble as a backend, Which one would you choose?
I'm trying to figure this out with a short pros/cons list:
