#ObjectScript

20

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.

The related package avoids adding %JSONAdaptor to each class but uses instead
SQL functions JSON_OBJECT() to create my JSON objects. With this approach, you can
add JSON to any class - even deployed ones - without any need for change or recompiling.

The trigger was the Export of M:N relationships as JSON objects or arrays.

Earlier this year I announced availability of a VS Code extension for coding in ObjectScript, Embedded Python or SQL using the notebook paradigm popularized by Jupyter. Today I published a maintenance release to correct a "getting started" problem.

Here's a video of the installation steps from the extension's README:

Why not try it for yourself?

In the sample below, an image file is encoded into a Base64 string in a class property, saved, decoded again with Base64, and restored to another file.

【Usage class】

Class User.test Extends %Persistent
{
Property pics As %GlobalBinaryStream;
}

Hello developers,

In this article, I'll show you how to run code at compile time with ObjectScript macros.

Here's a use case that recently led me to use this feature:

As part of a medical application developed for more than 20 years, we have a large number of parameters. Although we have procedures for documenting these settings, it can be helpful to have a quick view of which settings are actually used by the application code.

It's a feature of ObjectScript (perhaps widely known, perhaps not) that if you open the same object ID multiple times, you end up with the same OREF. For example:

USER>set obj1 = ##class(Sample.Person).%OpenId(1)
 
USER>set obj2 = ##class(Sample.Person).%OpenId(1)

USER>w obj1,!,obj2
1@Sample.Person
1@Sample.Person

Generally speaking, this is an important feature - you won't end up accidentally modifying the same record via multiple paths and losing some of the changes.

on red hat, but I would also be interested in a wider answer.

after running a benchmark for 40 minutes, I have been asked if any rollbacks occurred in that time. Rollbacks from SQL or objects.

The application does not record this, so I am looking for a system level record.

The journal entries do the necessary reverse sets and commit just like any transaction. So i don't think i can detect them there.

Currently I have a program that is going to be used to compare global nodes between namespaces. Using nested FOR statements I am stepping through global nodes and comparing between the namespaces, if the global values are different I then parse the node comparing each delimited segment.

This is working.

I want to now be able to set what global I am in as a variable to expand on this concept.
