What's the best way to replace character groups?

I want not to remove character groups as $zstrip does but to replace them with whitespaces.

$translate needs explicit character list.

Effectively I want to remove any characters besides letters, numbers and a small (known) subset of punctuation characters, replacing everything else with whitespaces.

Code golf is a type of recreational computer programming competition in which participants strive to achieve the shortest possible source code that implements a certain algorithm.

Here's a list of Code Golf competitions we had on Developers Community.

• Output 9876543210 without using numbers
• How can I make my text behave in accordance with gravity?
• Drawing Boxes
• FizzBuzz

And some interesting challenges:

• Can you crack the Black Box?
• Convert Cyrillic to Latin

Is there a way to set null in dynamic object without using %Set methods?

I have this method and I need to set NULL as, well, null and not string.

ClassMethod node(name) [ CodeMode = expression ]
{
{
    "name":(name),
    "content":($case(##class(%Dictionary.ClassDefinition).%ExistsId(name), $$$YES:"mycontent", $$$NO:"NULL"))
}
}

I want to execute initialization code on the start of my business process.

I thought OnInit is a way to go, but apparently not - ^dbg global remains empty:

Class Test.BP Extends Ens.BusinessProcess
{
Method OnInit() As %Status
{
    Set ^dbg = 1
    Quit $$$OK
}
}

Ideas?

I have two local instances:

• IRIS for Windows (x86-64) 2018.1.2 (Build 626_3U) Wed Jun 12 2019 19:07:59 EDT
• IRIS for Windows (x86-64) 2019.1 (Build 510U) Thu Mar 14 2019 14:13:37 EDT

I'm using Java Gateway to talk to external system.

Both instances are using the same:

• jar
• generated class
• java version

They are calling the same method with this java signature:

I have this fact table

And the cube which is pretty much 1:1.

I have build an MDX:

When I describe InterSystems IRIS to more technically-minded people, I always start with how it is a multimodel DBMS at its core.

In my opinion that is its main advantage (on the DBMS side). And the data is stored only once. You just choose the access API you want to use.

I have one persistent, xml-enabled class.
I need to convert objects of this class to XML.
However I need to project each object in different ways (depending on
where I send it), for example:

• Different list of attributes are projected
• Attributes have different names
• ...

Is there a way to do that with XML Adaptor?
