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.
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 ?
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.
Many of you publish your InterSystems ObjectScript libraries on Open Exchange and Github.
But what do you do to ease the usage and collaboration to your project for developers?
In this article, I want to introduce the way how to introduce an easy way to launch and contribute to any ObjectScript project just by copying a standard set of files to your repository.
When you export the Caché ObjectScript code to VCS (Git, SVN, Perforce, etc) do you export the Storage schema for persistent classes? If so, what are the Pro/Contra?
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 :
Embedded SQL is a tool that allows us to execute SQL statements in Caché Object Script. For example, to select the name of a person with a particular SSN from the Sample.Person class we can do the following:
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.
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)
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" }
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:
Hope most of you already familiar with project CachéQuality from @Daniel Tamajon. For those who don’t know about it, it is a static syntax analyzer for your code written for InterSystems products. It may help you to find and solve many different types of issues in your code, and even possible bugs before clients will find it in production. So, with help of CachéQuality you will be able to deliver a better product. You can find the complete list of rules used to check ObjectScript code here.
It was already available in Studio. And now it is also available in VSCode.
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 found one interesting moment in Cache Object Script. It doesn't have(or at least I didn't find) trimming function. By trimming I mean if a string has some whitespaces/tabs/carriage returns from very beginning or/and from very right, this function removes them.
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 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 - $1,000
And we provide winners with high-level badges on Global Masters.
I was wondering if there is any way to count elements from an array. I guess not as an array could be multi-dimensional and that would be a problem to return the number of elements inside the array.
I have a number of Business Process and due to the complexity these were created as "custom code" instead of BPL.
These processes currently invoke other components using SendRequestSync. For a couple of reasons I would like to be able to change these to use SendRequestAsync:
I would like to integrate SQL into our ObjectScript routines in order to illustrate how SQL can be used to minimize development time. However, there are two questions I have.
How does one iterate through the results of a SELECT statement?
(Originally posted on Intersystems CODE by @Eduard Lebedyuk, 10/12/15) The following code snippet outputs all filenames in the file path "dir" in the Cache/IRIS terminal. The class method "test" runs the code:
Class eduardlebedyuk.filenamesInDir Extends %RegisteredObject
{
classmethod test() {
// replace dir with file path you want
set dir = "D:\directory"
set dir = ##class(%File).NormalizeDirectory(dir)
set file=$ZSEARCH(dir_"*")
while file'="" {
write !,file
set file=$ZSEARCH("")
}
}
}
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.
dim msg as %Net.MailMessage = ##class(%Net.MailMessage).%New()
set msg.Charset="UTF-8"
do msg.TextData.Write("Dear "_Username)
do msg.TextData.Write("Line1")
do msg.TextData.Write("Line2")
