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.
The question has come up several times and I saw mixed answers and no quick example
My personal preference is using CPIPE device as you get back exactly the output you will get at the command line interface of your OS . The tricky thing is to stop reading in time. The example just displays what you normally see in your console. it becomes useful if you look for things that you can't get from any $system.whatever()
I'm having trouble parsing XML containing unicode characters which I receive from an external webservice. I believe my file is saved properly with UTF-8 encoding but the SAX Parser still throws me an error.
I have 2 classmethods: 1 general one (get) to make a request to a webservice and return the date, and 1 (getSportsPerDate) to make a specific call and then parse the data.
If you're solving complex problems in ObjectScript, you probably have a lot of code that works with %Status values. If you have interacted with persistent classes from an object perspective (%Save, %OpenId, etc.), you have almost certainly seen them. A %Status provides a wrapper around a localizable error message in InterSystems' platforms. An OK status ($$$OK) is just equal to 1, whereas a bad status ($$$ERROR(errorcode,arguments...)) is represented as a 0 followed by a space followed by a $ListBuild list with structured information about the error. $System.Status (see class reference) provides several handy APIs for working with %Status values; the class reference is helpful and I won't bother duplicating it here. There have been a few other useful articles/questions on the topic as well (see links at the end). My focus in this article will be on a few debugging tricks techniques rather than coding best practices (again, if you're looking for those, see links at the end).
In this article I would like to tell you about macros in InterSystems Caché. A macro is a symbolic name that is replaced with a set of instructions during compilation. A macro can “unfold” in various instruction sets each time it is called, depending on the parameters passed to it and activated scenarios. This can be both static code and the result of ObjectScript execution. Let's take a look at how you can use them in your application.
There are many ways to generate excel files using Intersystems, some of them are ZEN reports, IRIS reports ( Logi reports or formally known as JReports), or we can use third party Java libraries, the possibilities are almost endless.
But, what if you want to create a simple spreadsheet with only Caché ObjectScript? (no third party applications)
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.
First of all, let us have a brief overview of the framework.
The entire world is talking about ChatGPT and how Large Language Models(LLMs) have become so powerful and has been performing beyond expectations, giving human-like conversations. This is just the beginning of how this can be applied to every enterprise and every domain!
In March we are starting our first InterSystemsIRIS Programming Contest! It's a competition in creating open-source solutions using InterSystems IRIS Data Platform.
The topic for the first contest is InterSystems IRIS, Docker and ObjectScript!
The contest will last three weeks: March 9-31, 2020.
Prizes:
There will be money prizes for Experts Nomination - winners will be determined by a specially selected jury:
🥇 1st place - $2,000
🥈 2nd place - $1,000
🥉 3rd place - $500
Also, there will be Community Nomination - an application that will receive the most votes in total:
🏆 1st place - $1,000
And we provide winners with high-level badges on Global Masters.
It is with great pleasure that the CIUSSS de l'Estrie - CHUS is sharing the mocking framework it developed and presented at the InterSystems Summit 2017. I will update this post with more detailed instructions in the next few weeks but I wanted to share the code and presentation quickly :
I have come across several cases where I need to set a Date filter to send only send any admit/scheduled date past a certain point. We have a couple different date comparison functions but none looking at the true date. Most of them are date + 15 or etc. Does anyone have a good date function they have written to say if x > 20170102 ?
We are working on creating a metadata file to accompany PDF documents produced by one of our third party systems for ingestion into our DMS. One of the pieces of data that the metadata file must contain is the number of pages of the PDF document.
In Cache ObjectScript does anybody know if there is currently a way of counting the number of pages within a file (specifically a PDF) without invoking a non-Caché ObjectScript program/function from within Caché ObjectScript?
My Business process connector receive a Oru_01 hl7 message with an ED segment inside (Base64 pdf). How is it possible to extract it and create a pdf file within?
Here is the sample of function I have. I know it doesn't work but if you could help me, it would be perfect. Here is my function, the goal would be it create the file where I want and return me the link of the file.
Caché offers a number of methods for going through a collection and doing something with its elements. The easiest method uses a while-loop and lets you fulfill the task in an imperative manner. The developer needs to take care of the iterator, jumping to the next element and checking if the loop is within the collection.
I have a number of Business Process and due to the complexity these were created as "custom code" instead of BPL.
These processes currently invoke other components using SendRequestSync. For a couple of reasons I would like to be able to change these to use SendRequestAsync:
Sometimes, it comes in very handy (especially for the EAV model) to use array properties in a class and be able to qickly search by their elements: both the key and the value.
At the global summit in Phoenix, we (Lite Solutions) will be presenting a tool performing static code analysis on ObjectScript source files. You can see it in action at this URL:
I would like to know how to detect in Caché ObjectScript if data saved in string is number and furthermore, if it's type is integer.
I maybe found a solution:
set value = "44.2d3"
try{ set status = $INUMBER(value,"") if ('$FIND(+value,".")){ w "your variable: '"_value_"' is number and integer" }else{ w "variable is number but no integer" } }catch(e){ w "variable is not number" }
All time
