#ObjectScript

21

InterSystems ObjectScript is a scripting language to operate with data using any data model of InterSystems Data Platform (Objects, Relational, Key-Value, Document, Globals) and to develop business logic for serverside applications on InterSystems Data Platform.

Documentation.

I'm wondering how I would go about adding headers to a csv file which has already been created. I am unfamiliar with ObjectScript.

For example if I were to use R, I would simply write..

test <- read.csv("file/path/example/Extract.csv", header=FALSE)
colnames(test) <- c("A","B","C","D","E")

I do not have embedded Python installed either as I would know how to do it in that also.

How could I mirror this in ObjectScript please?

My current create file method:

Tutorial - Streams in Pieces

This tutorial is a follow on to Working with %Query
It was displaying the content of the input stream chopped in fixed-size chunks.
But often those streams are structured and have well-defined separators (e.g HL7)
So as a side subject of this tutorial, this chapter shows how to break a stream into PIECES.

It is exactly the same idea as the $PIECE() function for strings with some add-ons.

My previous article introduced you to SQL based Basic Class Query
where a clever wizard created all the required code for you and your essential
contribution was an SQL statement.

Now we enter the real Custom Class Query that provides more freedom but
requires a deeper understanding of the mechanic behind the scene.
The full code example is again on GitHub

At least three different ways to process errors (status codes, exceptions, SQLCODE etc is given in ObjectScript. Most systems have status, but for a range of reasons exceptions are more convenient to manage. You spend some time translating between the various techniques dealing with legacy code. For reference, I use several of these excerpts. It is hoped that they will also support others.

Hi all,

I might be losing my mind or do not understand how ObjectScript does string comparisons, but the following does not look right to me.

Is it really possible that you can't compare non-numerical strings other than with an equals or not equals?

USER>w ("45" < "46")
1
USER>w ("45" > "46")
0
USER>w ("V45" < "V46")
0
USER>w ("V45" > "V46")
0
USER>w ("V45" <= "V46")
1
USER>w ("V45" >= "V46")
1

In Python:

Any ideas on how this can be solved?

I need to use it with some Unicode text, in Docker image. And get this error. And documentation says nothing about it.

USER>do $zf(-100, "/SHELL", "echo", "test")
test

USER>do $zf(-100, "/SHELL", "echo", "test тест")

DO $ZF(-100, "/SHELL", "echo", "test тест")
^
<TRANSLATE>

I know that it works in some Linux environments without Docker, but no idea where is the difference.

Hi:

I don't understand how to use this open exchange item for auto creating deleting items. I think it assumes knowledge in the steps of how to use it which i don't get.

Added the code into dev on SRFT.Utility.DeleteHelper.OnDeleteSuper and SRFT.Utility.DeleteHelper.AddHelper

current class is

Hi Community,

A long time ago, I create a package for a String datatype that works with Regular Expression. It is quite a simple solution.

This can work well with packages like the OpenAPI-Suite, where you can then use the "Regular Expression String" as the type for properties of the validator objects where the Swagger contained a Regular Expression.

I am proposing we start a common package of datatypes for use. The package name to use can be provided by the admins.

Hi Developers!

Suppose you have a persistent class with data and you want to have a simple Angular UI for it to view the data and make CRUD operations.

Recently @Alberto Fuentes described how to build Angular UI for your InterSystems IRIS application using RESTForms2.

In this article, I want to tell you how you can get a simple Angular UI to CRUD and view your InterSystems IRIS class data automatically in less than 5 minutes.

Let's go!

Hello, friends who are developing IRIS. I recently participated in the InterSystems Developer Tools Contest. This time, I made a tool based on the idea described in an article I published earlier as a template for quick query of messages. Currently, you only need to establish entity classes in IRIS, Then record the message corresponding to the entity class in the specified lookup table, and all the key fields generated in the message can be inverted indexed (the concept in ElasticSearch), which is convenient for quick query. The following is the design idea of my program.

Hi all,

In the days when I was still using studio, the indentation character of choice was tab, due to misalignment of code when using non-monospaced fonts.

In VSCode when I create new class files, this defaults to 4 spaces. Where and how do I set the default indentation for ObjectScript class files?

Also, with python it should be spaces. So what is recommended when doing python script inside objectscript classes?

Thank you.

When requesting /MDX2JSON/PivotVariables/Patients?Namespace Patients shoud be passed to a method but its not. When argument passed directly into the method it works.

<Route Url="/PivotVariables/:Cube" Method="GET" Call="WritePivotVariablesForCube"/>

Has something changed in IRIS and this syntax is deprecated, or is there a bug and the colon is ignored? What could it be?

This question is continuation from https://community.intersystems.com/node/534811

In our team, there are several developers working in parallel on different projects. To ensure this distributed collaboration and high-quality code reviews, we rely on version control with Git. Our challenge is to harmonize the unique characteristics of InterSystems products and the possibilities of Git and Docker.
