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.
Curious if there is a string function which can transform a delimited string into an array without looping through $Piece...such as "a,b,c,d,e,f" into array(0)=5,array(1)="a",array(2)="b" etc
I have great news for you. A few days ago, GitHub was updated with the latest version of linguist project, which is being used to recognize source code types in repositories. It helps to determine which programming language had been used in every file of the repository. Repository statistics section shows the results of this module work.
Also, you can search across all available GitHub repositories for any chosen language.
Say you have a DICOM document with an input information sequence with many sequence items. You could access every item one by one by looping and querying the path by passing it to the GetValueAt method as demonsrated below.
This works but there are some performance issues on my system if the document has to be read for each query (as far as I know, that is the case on my system). Is there a way of querying a path, which would return the sequence items as an array? I think I am missing something. With 900 items the process takes around 20 seconds currently.
I have very good news for the developers, who are using GitHub to host projects with InterSystems ObjectScript. GitHub introduced the support of InterSystems ObjectScript this week!
How does it work?
Now all the .cls files in your repository are considered as InterSystems ObjectScript and highlighted according to the language rules of ObjectScript. For example WebTerminal, Samples-Data.
During testing your code you are often confronted with the need to examine the actual content of an object. Either using ZWRITE or $system.OBJ.Dump() you get a picture of simple properties as "--- attribute values ---" while "--- swizzled references ---" are more confusing than informative and with "--- calculated references ---" you are just left in the lurch.
This small helper class allows you to dump an object to terminal or e.g in background to some stream for later review. By default, you see just properties with content,
I have a custom process that is parsing HL7 and inserting it into a table. Periodically the inserts fail with # due to error: ERROR #5803: Failed to acquire exclusive lock on instance of....
Traditional databases would wait until the lock is removed then do the insert, but cache fails. I'm sure it's my coding approach.
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:

I want to search a process ID in Object Script using the reference variable e.g. 1119102928 and kill that process ID. Please guide how it can be achieved.
PHP, from the beginning of its time, is renowned (and criticized) for supporting integration with a lot of libraries, as well as with almost all the DB existing on the market. However, for some mysterious reasons, it did not support hierarchical databases on the globals.
Globals are structures for storing hierarchical information. They are somewhat similar to key-value database with the only difference being that the key can be multi-level:
In the documentation it says to set the username and password properties of the connection object but these properties don't exist and without authentication I can't connect to the MQ queue.

I believe my current villain is “incremental compiling.” I was able to compare early compile output with later compile output:
Compilation started on 04/10/2019 10:46:32 with qualifiers 'cuk'
Compiling class UnitTests.Task3496 incremental compile detected
Compiling routine UnitTests.Task3496.2
Compilation finished successfully in 0.800s.
Have some free text fields in your application that you wish you could search efficiently? Tried using some methods before but found out that they just cannot match the performance needs of your customers? Do I have one weird trick that will solve all your problems? Don’t you already know!? All I do is bring great solutions to your performance pitfalls!
As usual, if you want the TL;DR (too long; didn’t read) version, skip to the end. Just know you are hurting my feelings.
Hi! I've been fiddling with linked tables to get data from other servers, and I encountered a problem that I'm curious about. Maybe I'm not using these tools as intended or there's more going on, so I'm asking here.
I'm running a query on linked table A, something simple like this:
I was trying to create a query that can be exposed as a stored procedure (function actually) that would return a resultset with a random number of columns.
Unfortunately, it seems that unless I specify the ROWSPEC annotation on the Query method, I won't get any columns exposed. I was hoping to implement QueryNameGetInfo method and specify the names and number of columns I would be returning dynamically. But it seems that GetInfo information is simply ignored.

Well, we now have two different platforms Caché and IRIS. With so many changes, that it makes so many difficulties to have the same sources for both platforms. I'm not arguing about the reasons for it. Some of the changes are really reasonable.
It's good when I can import code from Caché to IRIS and get it worked after all background job was done. In Caché we have %CacheStorage type used for Storages. In IRIS it automatically converts to %Storage.Persistent. So, If I develop on IRIS, I will have incompatible sources for Caché.

I am still new to cache objectscript and am trying to figure out how I would go about removing the escape characters from my JSON below. When I call the $toJSON method it's adding the "\" character in the file path.
I have a need to dynamically create a web application definition in a namespace using ObjectScript. I am having trouble finding a cache class or routine that let's me do this.
