#InterSystems IRIS

In this series of articles, I'd like to present and discuss several possible approaches toward software development with InterSystems technologies and GitLab. I will cover such topics as:

• Git 101
• Git flow (development process)
• GitLab installation
• GitLab Workflow
• Continuous Delivery
• GitLab installation and configuration
• GitLab CI/CD
• Why containers?
• Containers infrastructure
• CD using containers
• CD using ICM
• Container architecture

In this article, we would talk about building your own container and deploying it.

Hi Everyone!

If you are attending VMworld Las Vegas remember to look for two sessions on InterSystems IRIS in the content catalog!

As a result of Evgeny's recent questions regarding the use of QEWD.js with IRIS in another post, I thought it would be a good idea to create a separate post focusing specifically on how to use QEWD.js to create REST APIs for IRIS.

QEWD.js is, of course, a Node.js framework, and all the REST API code can be written entirely in JavaScript.

Hi Community!

Coding guidelines discussion. Consider you have For with one command in the cycle. Here are the options:

One

For i=1:1:1000 set ^Test(i)=""

Two

For i=1:1:1000 {
 set ^Test(i)=""
}

Same for the "If":

if a set b=a

or

if a {
 set b=a
}

Your choice? Or maybe even other options?

This code snippet allows for a file on the web to be saved into the file system. Specify the server and GET request, as well as the directory the file should be saved to. The class method "test" runs the code:

Class objectscript.saveFileHTTP Extends %RegisteredObject
{
    classmethod test() {
        Set httprequest = ##class(%Net.HttpRequest).%New()
        Set httprequest.Server = "docs.intersystems.com"
        Do httprequest.Get("documentation/cache/20172/pdfs/GJSON.pdf")
        
        Do $System.OBJ.Dump(httprequest.HttpResponse)
         
        Set stream=##class(%FileBinaryStream).%New()
        Set stream.Filename="c:\test.pdf"

        Write stream.CopyFrom(httprequest.HttpResponse.Data)
        Write stream.%Save()
    }
}

Did you know that Caché (and now InterSystems IRIS) has available parser for ObjectScript ?

Well, technically, lexer. It hides under the name of %SyntaxColor class. This class provides API to the DLL used by Studio to do syntax highlighting. As a result if works only under Windows.

This code snippet changes all passwords in a system to a specified string. The two literal strings at the beginning of the snippet can be adjusted to edit the system or password string. The class method "test" runs the code:

Hi Community!

I'm pleased to announce that InterSystems IRIS is available on Microsoft Azure Marketplace!

→ InterSystems IRIS on Azure Marketplace

This is the second public cloud offering of InterSystems IRIS after recently announced Google Cloud Platform support.

IRIS is a powerful platform and one of the new features is the Java Business Host (DOC: Connecting Systems Using Java Business Hosts) that allow you to develop Business Services and Business Operations directly in Java (JavaDocs of the InterSystems Gateway Package).

Hi Community!

We try a new approach to the InterSystems Developers YouTube Videos called "Coding Talks"!

Coding Talks is a short video in which the developer demonstrates a particular feature or functionality of InterSystems Data Platforms which he/she uses to in coding. Typical format: the face on side and editor with ObjectScript.

Check this video I made by myself participating in Advent of Code 2018 and coding with InterSystems ObjectScript in VSCode.

Hi

Totally new to IRIS and Cache.

Trying to evaluate it and work out how we could use it.

As a standard application database. Object or relational etc. does not matter.

Issue is ObjectScript.

So:

1) Can we develop, maintain and use an IRIS database and never use ObjectScript i.e. use only Java, Python, C++ interfaces etc. (exactly which one does not matter)? Would that make designing and using the IRIS database more prone to inefficiency and error?

(Originally posted by Timur Safin on Intersystems CODE, 3/2/15) This code snippet is a routine that parses options saved in an arguments array. The subroutine "test" runs the code:

The following code snippet includes a class method "test" that runs code to find a class based on the class's name. "test" takes one argument, which is the name of the table:

Class objectscript.findTable Extends %RegisteredObject
{
    classmethod test(name as %String="mytable")  
    {
            #Dim result as %ResultSet
            #Dim tName as %String
            #Dim contain as %Integer
     
            Set contain=0
            Set result = ##class(%ResultSet).%New("%Dictionary.ClassDefinition:Summary")
            Do result.Execute()

            While(result.Next()) 
            {
                Set tName=$get(result.Data("Name"))
                &sql(select position (:name in :tName) into :contain)
                Write:contain'=0 tName, " ... ", name, " (", contain,")", !
            }
            Return $$$OK
     }
}
