Announcements

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).

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.

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”

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?

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.

Having developed systems using Caché ObjectScript and Ensemble on various projects over the last 4 - 5 years I'm considering trying for some certifications. I've found details of the Caché Systems Administrator and Caché Application Developer certifications but have a couple of questions:

1) Is there a certification for Ensemble Application Developer?

2) Are any sample questions and/or practice exams available?

Thanks

How suitable is Docker for standalone deployment of an Ensemble version and Ensemble application together?

The context is deployment by an application partner of an integration application and the supporting Ensemble version as a single package (single file ideally), to multiple environments and to multiple customer sites.

I don't have experience with Ensemble on Docker so I'm wondering what gaps and pitfalls may exist.

I know this may sound like sour grapes, but really it is not.

I hear all the exciting things about the up coming InterSystem Conference, and I am sure it is.

But it is way, way out of my price range, and I am sure out of the price range of most of the Cache/MUMPS developers, without company backing.

Just wondering what others think.

When I go through the Atelier Cheat Sheet on the connection configuration, it talks about an Eclipse master password and asks for two hints to remember the master password. However, it does not specify the master password. I can only assume the master password is the same as the Cache instance password.

Can anyone shed some light on this master password, where or how it is used, and any other useful information?

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 guys,

I'm curious about the development processes of those of you using Angular. 

The starting point is that, somewhere, there lives an Angular project full of (mostly) typescript files.  Eventually, those files need to be built, and the resulting built files served up to a browser.

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.

Metadata

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:

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.

Documentation here lists the kinds of members a class definition may contain. In summary:

  • Parameters
  • Methods
  • Properties
  • Class queries
  • XData blocks
  • Projections
  • (and some that are relevant only for persistent classes):
    • Storage definitions
    • Indices
    • Foreign keys
    • SQL triggers

Later in the same document, a section headed "Class Member Names" contains this warning:

Are there any BDD testing automation implementations within Mumps/Cache Objects already in existence?

We are looking at using Cucumber for our Java regression test automation and would like to use similar feature file testing with the Cache code.


Looking to use something existing before building it.

Regards,
-Karl

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?

I've tried

Hello, our customer, large industrial company, is considering modernizing their old CSP application so it can run on multiple client device types, using responsive design.

They have a lot of experience with CSP and some ZEN.

They are new to REST and have some limited knowledge of javascript - perhaps not enough to the extent used by client framework.

Does anyone have a framework or a set of templates that you would be willing to share?

Thank you!

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

Scott

When I try to open a DTL in the tabbed editor I always get this error:

You are using Internet Explorer 7. This version is obsolete and is not compatible with diagram editors. Please update Internet Explorer to a recent version.

My actual Internet Explorer is version 11.

I'm running Eclipse Photon.

  Atelier IDE    1.3.141    com.intersystems.atelier.feature.group    InterSystems Corporation

The same error occurred with Atelier 1.2 on Eclipse Oxygen. I've never been able to get this to work.

My understanding is that IRIS is a new technology and does not replace Cache or Ensemble and to that end is more of a modernization than a repackaging. Is that accurate?

Is IRIS and HealthShare heavily penetrated in the payer space of primarily dominate in the provider space? What is the trajectory for InterSystems to penetrate the payer landscape?
