API to import/export routines

This is an article on the InterSystems FAQ site.

1. Export API

a. Use $system.OBJ.Export() to specify individual routines to export. For example:

do $system.OBJ.Export("TEST1.mac,TEST2.mac","c:\temp\routines.xml",,.errors)

The format to specify is routine name.extension, and the extension is mac, bas, int, inc, obj.

Errors during export are stored in errors.

Code Golf: Parenthesis

Our previous code golf ended with an overwhelming win, so now it's time for another one.
Parenthesis Hell is a Lisp-like esoteric programming language(esolang).
As a Lisp-like language, the code consists only of nested matched pairs of opened and closed parenthesis.
Your task is to write a method that receives a string of parenthesis and returns 1 if the order of the parenthesis is valid. For example, the string of parenthesis (())() is valid because it contains a matched pair of opened and closed parenthesis at each position. The string ()((()))) is not valid because it contains one unmatched parenthesis.

Jupyter and IRIS - The Simple Version

There are several great articles in the community showing how to use Jupyter and InterSystems IRIS together, and I encourage you to check them out in the link at the end of this article for more in depth understanding.

This is just another one, the difference is on the simplicity. Do you want to just start a container where Jupyter is already connected to an IRIS instance? Then this is for you!

Visual Studio Code Development

Please, I am having trouble connecting to one of several Health Share servers using ISC's Visual Studio Code add-on.

Installation seemed to go smoothly. I have InterSystems's Studio and was able to automatically pull in my existing connections. However when I try to make a connection it fails.

Here is a configuration of one connection slightly edited for security:

"xxxx-hsiecommon-base": {

"description": "This has been created by the CCR system export.",

"username": "therock",

Good morning

I'm probably overlooking something very basic, but I'm running on Win2016 with Cache 2016.2 - All the work I am doing is in INT routines, but I'm making some calls to the Host File system using $ZF(-1).

I have a few mapped Network drives that are mapped in Windows, typically these are locations where I want to back up some files.

My process is quite simple:

1. Read data

2. Zip data files using RAR

3. Create folder on Network drive

4. Move RAR files to new network share.

I've tried a few different commands:

Atelier - the first three months

Almost exactly three months ago Atelier 1.0 was released. If you are an early adopter and have any feedback to share, here's a thread we could use.

For instance, during the Field Test I posted this article about the two explorers, Atelier Explorer (AE) and Server Explorer (SE). Presumably more people are now using Atelier, so I'd be interested to hear how it's going.

I installed the Cache client along with Atelier on my mac.

My question is:

How do I access the Management Portal on a mac?

My Atelier stand-alone app allows me to use the Cache instance, but how do I get to the Management Portal to set up security and create new namespaces, etc.?

Also, where to I check to see when Cache is actually running?

Thanks.

I want to limit the length of the value of a textarea in Zen. In HTML the textarea element has a 'maxlength' attribute, but the Zen component doesn't have an equivalent property. Is there any way to add a maximum length in Zen short of creating my own custom component?

Recovering a Mirror after crash

Here we are again with an article related to the Mirror!

In the previous article we saw how we could configure a Mirror between two IRIS instances, one acting as an active node and the other as a passive one. This mirroring system works on the transfer of a journal file that keeps the instance that works as a passive node continuously updated, but what happens if due to some communication failure or permissions of the journal file it is not transferred correctly?

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"))
}

Modifying %Stream contents

I have a %Stream that I want to insert some text into the middle of. I create a new stream called pNewContentStream from the original stream, then I do a MoveTo in pNewContentStream to get to the byte position I want to insert into but when I do my Write, my pNewContentStream gets obliterated with only the text that I wrote, the original content goes away and all I'm left with is my Write text.

I was hoping someone might be able to help me.

I am after some code i can run (preferably in terminal) to return details of an SQL Gateway Connection (ODBC).

Scenario is a forgotten password for a server that needs its connection details replicating on another production.

I know this can be done with Credentials by simply querying the 'Ens.Config.Credentials' class however i cannot seem to find the equivalent.

Good afternoon, I have image files stored on disk. I would like to display those images in an <image> control as the end user clicks on rows in a tablepane. I already do this with image data stored in a cache database:

s imageComp = %page.%GetComponentById("ImgTab"_tLdCnt)
s imageComp.disabled=0
s tId=rsId.Get("ID")
s tPageObj=##class(My.PageObj).%OpenId(tId)
s oid=tPageObj.ImageBLOB.%Oid()
s encryptedOid=..Encrypt(oid)
s imageComp.src="%25CSP.StreamServer.cls?STREAMOID="_encryptedOid

From a browser, an XMLHttpRequest to a CSP page on a different server will obviously hit the CORS security check.

To get around this I can set the Access-Control-Allow-Origin header on that particular CSP class.

However, setting any request headers on the XMLHttpRequest object will trigger a pre-flight OPTIONS request.

This OPTIONS request is not handled by the target CSP page and the Access-Control-Allow-Origin header is never set, triggering a CORS error.

IRIS configurations and user accounts contain various data elements that need to be tracked, and many people struggle to copy or sync those system configurations and user accounts between IRIS instances. So how can this process be simplified?

In software engineering, CI/CD or CICD is the set of combined practices of continuous integration (CI) and (more often) continuous delivery or (less often) continuous deployment (CD). Can CI/CD eliminate all our struggles?
