Hi Community,
This post is to introduce one of my first project in COS, I created when started to learn the language and until today I'm keeping improve it.

The CosFaker(here on Github) is a pure COS library for generating fake data.

cosFaker vs Populate Utils

So why use cosFaker if caché has the populate data utility?

Ok the populate utility has great things, like the SSN Generator for example, but what to do when you have a field with a long description of a product? How to check if that table will list the emails or if that calculated property will count the days of the last user interac

Hi all.

I'm currently working with a system needing results from a lab system, and they can only accept a single OBR per R01 message.

The R01s from the source have multiple OBRs, so I need to be able to send a message per OBR.

I found a similar post where the example was using a BPL, however there's some additional trickery processing that I already have working within an ObjectScript Business Process and would like to avoid trying to recreate in a BPL.

Any sample code will be greatly received 

Hi,

Is there any functionality available to generate FHIR bundle id (GUID)?

Thanks
 

Besides objectscript's own list, array data structure, are there any other data structures that have been implemented, similar to the "collection" package in java, or is there a ready sorting tools for the collection class.

I am working on tweaking our current patient load process. The roster input is in text pipe delimited format, parsed out and transforms it to a standard HS.Message.PatientSearchRequest, and send to business process for patient matching. Result is transformed into a standard ADT HL7 message using EnsLib.HL.Message class. I would like to know if there is another class I can use that will transform my output to a text flat file pipe delimited instead of HL7 format? any advice on how to do this is greatly appreciated.

Thanks!

Greetings, InterSystems community!

I am pleased to announce that the web terminal project, Caché WebTerminal version 4 gets its release! After long period of enhancing this web application from 2013, it came to the version 4, which features major stability and security improvements, intelligent autocomplete and syntax highlighting, convenient SQL mode and a lot of other useful features.

The goal of this article is to spread the knowledge about this project over the InterSystems community.

Hi Developers!

A question to those who use VSCode to code InterSystems ObjectScript.

Suppose you have the ObjectScript code on IRIS server and you want to export it into the desired folder.

And you have VSCode connected to the server.

What is the way to tell VSCode that I want to export classes into some particular folder in /package/class.cls way?

E.g. into:

/project_folder/src/cls/Package/class.cls

and project_folder is opened in VSCode as the folder of the project.

Here are a few examples of conversions and operations you might need, along with links to documentation where you can learn more.

At the time I wrote this, Eastern Daylight Time was in effect for my Caché system.

How Caché keeps the time and date

Caché has a simple time format, with a longer range of recognized dates compared to some other technologies.

The current time is maintained in a special variable $HOROLOG ($H):

USER>WRITE $H64146,54027USER>

The first integer is the count of days since December 31, 1840. The second integer is the count of seconds since midnight of the current d

Hi,

I have the requirement to dump large result sets into files. I am currently using %SQL.Statement and the result set created by it.

The DisplayFormatted is used to write a CSV. The query I used to test does not contain any filters, it is just a select * from a table with 16 million rows.
The file created is 2GB in size. The issue I have is that it takes 8 hours to create this file.

I have seen in the past that file streams write fast at the start. As the file continues to grow, the process' memory usage increases until it reaches the max allowed. After that, the file writing slows down si

Hi all, I am new to IS Objectscript and I would appreciate some assistance regarding this. 

I am trying to find out how to count the number of elements within a dynamic abstract object and I am having some trouble using the size method.

Here is the code below:

The key value pairs are originally in JSON and I would have converted it in to an object for use.

Class JSON.Test {

ClassMethod Test()
{
    set obj = {"byr:":"1937", "iyr:":"2017", "eyr:":"2020", "hgt:":"183cm", "hcl:":"#FFFFFD","ecl:":"grey", "pid:":"028048884"}
    set passport1 = {"ecl:":"grey","pid:":"860033327", "eyr:":"2

I'm looking for a way to get the message header ID for the current message in a Request to a Business Process.

I've located some code that gives me what I need, but it runs the risk of violating the "abstraction layer" ISC has in place around such things. And while I very much appreciate their efforts at keeping things simple for me ... well, sometimes you just have to dig through the guts to get what you want.

Is there a documented, deprecation-resistant method for getting at %Ensemble("%Process").%PrimaryRequestHeader.%Id() from within a  BP?

I've been tasked with an interface that needs to supply some additional metadata for the indexing of HL7v2 messages. After toying with a couple of ideas, I thought that it would be useful to subclass EnsLib.HL7.Message, add a %DynamicObject property, and store the metadata in it (it ends up getting sent to the target in JSON form anyway).

And, well, it seems to work just fine ... so far.

I seem to remember that %DynamicObjects are not persistent, and for that reason not something you would normally stuff into a database. I was a little surprised when things worked as I had hoped. With ZWRITE

for debugging purposes of complex applications.

Hey I am very new to Intersystems Objectscript and I am trying to find a way of extract 4 digit numbers from a stream.

I have a stream full of results 

2334

3434

5543

4334

And I am trying to remove each 4 digit grouping from the stream.

I have tried the following for loop 

for i=1:1:$length(result) {

set curr = $extract(result, i)

write !, curr

set count(curr) = $get(count(curr)) + 1

}

Unfortunately the loop extracts one digit.

Does anyone have any suggestions on how to solve this ?

Hi all

I'm trying to recreate this method below in Cache/IRIS. 

https://en.wikipedia.org/wiki/Luhn_mod_N_algorithm ISO-7812-1 (LUHN-10)

I've been following the javascript example. It seems simple in theory but i'm struggling with which cache methods to pick.

$LENGTH, $System.SQL.FLOOR() - seem ok

$EXTRACT - I think for .charAt (though may need to correct base)

$FIND - for .indexOf

Any suggestion which would be the best ones for the job?

Thanks

Dan

Hi Community,

We're pleased to invite you to the upcoming webinar in Spanish called "Learning ObjectScript from scratch"!

Date & Time: May 25, 4:00 PM (CEST)

Speaker: @David Reche, Manager of the Dev Community in Spanish

The webinar is aimed at:

Awhile back the Developer community helped me with a situation I was having... How to loop through a Repeating Segment and Single Filed, example OBX().5, within a Business Process Rule and compare it against a Data Lookup table.

Well now I need to take it a step further. I need a way to loop through OBR() segment, and loop through OBR().4() and the subfield 4.1 and compare it to a Data Lookup table.

So I thought I could copy my existing function code and add another level to it, but its not returning what I would expect.

ClassMethod DoesValueExistRepeatingSegmentFields(pHL7Msg As EnsLib.H

Hi developers!

I have an existing CSP app and I want to add a role to it. How can I make it programmatically?

I am updating the PV1 segment with values from the database but when I get two values back I dont know how to separate them with a tilde and insert. Any advice for me on that?

so if I get two values returned

my PV1.7 segment should be :  

My current code is as below: It works fine for one value, but when there are more than 2 values returned I need to find a way to include it

Hi Community,

Please welcome the new video on InterSystems Developers YouTube:

⏯ Visual Studio Code for ObjectScript

Following instructions on this page https://docs.intersystems.com/latest/csp/docbook/Doc.View.cls?KEY=D2IMP… I am trying to create a Data Connector to be used as a base class for a cube with update support.
That page suggests that putting an SQL query inside XData block is not suitable for a Data Connector that supports updates.
Later it also suggests that to enable updates your SQL query must include 

WHERE $$$RESTRICT

Providing an example of it in XData block example like this

<sql>SELECT A,B,C FROM MyApp.MyTable WHERE $$$RESTRICT</sql>

Announcing gj :: locate.  A simple extension for VS Code that will help you get to the source of your errors.

In VS Code, using either the Serenji extension or the basic InterSystems objectscript extension, this small add-on will open the appropriate class or routine and position you at the exact line where an error occurred.

No more tedious counting of lines to find <UNDEFINED>zCredit+206^Ledger.Invoice.1.  Instead, with gj :: locate you can get there with just a couple of clicks.

This 20 second video tells it all:

Download now and enjoy getting to the source of your errors.

Hi Community,

I am trying to access another process's content of objects like %request and %session. I am using the class/method "%SYS.ProcessQuery:VariableByPid". Does anyone knows how to get the value of the properties like %request.Data("ID",1)  from one process that is running on the DB server?

Example of what I am trying to do:

        set rs=##class(%ResultSet).%New("%SYS.ProcessQuery:VariableByPid")
        set tsc=rs.Execute(ProcessID,"%request")
        while rs.%Next() { 
            w "Name:"_$g(rs.Data("Name")),!
             w "Value:"_$g(rs.Data("Value")),!
        }
        do rs.C

You may think it isn’t too difficult to get from label+offset^routine to the actual source line responsible for the error.  For an expert it isn't that hard... most of the time.  But there are enough oddities and special rules that even an expert can get it wrong, whilst spending a lot of time trying to get there.

gj :: locate is the latest tool from George James Software – it debugs any error, class or routine by converting the location of an error in compiled .int code to the corresponding location in your source, and then taking you right there.

Image this scenario…

I checked out a Git-Branch and want to Import all Objectscript-Objects to my localhost.

While using Import without Compilation I receive a lot of errors.

request to http://127.0.0.1:57772/api/atelier/v3/TSTCBW/doc/MusLT01LCOD.int?ignore… failed, reason: connect ECONNREFUSED 127.0.0.1:57772

While using Import and Compile I receive much more of this errors.

Is there a setting, that I have to key in?

Or how can I synchronize my namespace to test my changes?

I have a CSP page that is supposed to show some user info (Full name and some other properties retrieved from AD)

I am unable to get them outside of %SYS namespace using Security.Users class. Is there another mechanism to do that, or I am using Security.Users class incorrectly?

Hi folks!

Often while debugging you want to know the values of all the parameters.

Using VSCode Debugger is not an option.

What do you use to know what parameters came to the method?

My hope if you have a "magic" macro that will store all the variables with their names into a global?

And share your approaches, please?
