"IF THEN - $SELECT - $CASE" - What is the best way?

Hi all,

I'm wonder what could be the best way convert the sentence "Switch" C# into Cache code.

int caseSwitch = 1;

switch (caseSwitch)
{
    case 1:
    Console.WriteLine("Case 1");
    break;

    case 2:
    Console.WriteLine("Case 2");
    break;

    default:
    Console.WriteLine("Default case");
    break;

}

My first attempt was:

%Status vs Other Return Values in Caché ObjectScript Methods

Hi, folks!

There is an interesting discussion in the neighboring topic which raises a question for me: is there any reason to have %Status as a return value for COS method?

n00b questions

Hello,

I have some beginner questions as I am working through the InterSystems Cache learning path:

- Where I work, we us Cache, but we often learning about and train on MUMPS. No one really talks about or mentions MUMPS here, but my understanding is that ObjectScript is basically MUMPS plus whatever new things InterSystems put on top of it. Is that a fair assessment?

Get variables list

Hello!

In Caché there is a way to print all current variables using write command without arguments:

USER>set Einstein = 1879
USER>set Mozart = 1756
USER>write
Einstein=1879
Mozart=1756

But is there a way to get a list of this variables? I am looking for something that would return value like $LB("Einstein", "Mozart") for this case.

Thanks!

Cache annotations mini-framework

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:

Http Response Parsing JSON string or stream

Hello community,

I am trying to parse the below HttpResponse in Cache. Cannot get the Iterator to work. Is there a single loop which can parse both or single messages and grab the error?

{
error:[
{ txt1:'error msg1'},

{ txt2:'error msg2'},
]
}

{
error: {
txt1:[
'error msg1',

'error msg2'
]
}

Thanks,

Git behavior

We are going to start using Git within Cache.

One question came up - if the branch that you checked out does not have the class or mac file, what is the correct thing to do?

Should we delete from Cache or should we just keep it?

I'm leaning more towards deleting it because Cache should reflect what is in your work folder in git. But other team members are saying to keep it.

Bizarre Behaviour when generating HTML to Android Phone

Hi,

We are using Cache to generate HTML pages (complete with Javascript), which we are reading in an Android phone App's WebView.

If, when we generate HTML as follows:

<html>

<body bgcolor='red'>

Hello World

</body>

</html>

Reading this is iPad gets what you would expect, a red page with Hello World written in it.

However in Android phone, the page is both white and blank.

How to sync Server and local cache code using Visual Studio Code

Hi all,

I wonder how to sync my server code to my local code using Visual Studio Code.

Previously, using Atelier, you could open a view of server and can copy the code to the current project, also if I change a BP, I could sync the code because I had a signal that It's warning me that there was a change and it needs to be updated.

I thing i shouls opening the ObjectScript: Explorer and select the code directaly, and right click -> Import and compile current file (Ctrl + F7)

Is it possible to pass ClassMethods as arguments to another ClassMethod?

just wondered if there was a way to pass functions for execution to another function so that events can occur before and after?

like :

d ..MethodA(
   ..Method1("var"),
   ..Method2(0),
   ...
)

edit:

I managed to get it working with execute but is there a cleaner (easier way)?

Is there a function similar to Oracle's CDC in the cache database?

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.

Include CSP in CLS.

Is there any way to include a CSP page within a CLS?
Example: #Include file.csp

Context: I work with a legacy that most screens are built using only CLS. I'm trying to change this by separating the frontend layers to be built only with CSP and backend layers using CLS. I improvised a method that injects an iframe to render the CSP in CLS through that iframe, but I'm still not happy. I need to know if there is any way to include this CSP using some specific resource for this.

Healthshare/Ensemble/Cache deployment tool? Anyone every created one?

I'm working on a proposal for a deployment tool development project and I was wondering if anyone had any experience with such a thing.

We use Healthshare and implementations for new clients are tedius and lengthy. Lots of ensemble service, registry value, lookup tables, namespaces and other things have to be created and configured.

I would like to create a Zen or CSP page based deployment tool that can do all this with a few parameters and some custom code.

What Is the Best Object Callback for Insert Operations: %OnBeforSave(), %OnAddToSaveSet(), %OnAfterSave()

Hi!

I'm saving object instance using RestForms.

RESTFormsUI calls %Save() for me, which is great. But I want to set the property CreationDate with the current date for every new record being inserted.

So object callback implementation seems as a reasonable option. I did the following:

WebSockets vs Long Polling vs Short Polling?

WebSockets look to be supported reasonably well in Cache. I have yet to use them in production so I am wondering how well it has worked for other developers.

In particular what happens when the browser does not support WebSockets, or when a firewall blocks the connection.

Have you had to write your own long polling fall-back?

I've read the documentation and found this interesting article...

Are there any short ways of serializing COS entity to the string? I am searching for something like .$toJSON() , but I need Caché 2013.* support.

The one way I supposed to work is to use $listbuild:

set list = $LISTFROMSTRING(str,",")

list=$lb("1","2","3","","","5")

ISCAgent Auto-Startup in a Mirror Configuration on a Veritas Cluster

ISCAgent is automatically installed with Cache, runs as a service and can be configured to
start with the system. This is fine – but the complication comes when this is on VCS clusters with
Mirroring on. When installing a Single Instance of Cache in a Cluster, point number 2. Says “Create
a link from /usr/local/etc/cachesys to the shared disk. This forces the Caché registry and all
supporting files to be stored on the shared disk resource you have configured as part of the
service group.”
