Hi! I have a promblem with ##class(%File).Exists -method and scandinavian characters.

Ensemble: Cache for UNIX (Red Hat Enterprise Linux for x86-64) 2018.1.2 (Build 309_5U)

I have a business service (EnsLib.EDI.XML.Service.FileService (charset=binary)) which reads XML-files from the server and transmits those to the business process. BP request class is EnsLib.EDI.XML.Document. In BP I have code block

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

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:

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

Hi Developers!

Often when we develop some library, tool, package, whatever on InterSystems ObjectScript we have a question, how we deploy this package on the target machine?

Also, we often expect that some other libraries already installed, so our package depends on them, and often on some particular version of it.

When you code on javascript, python, etc the role of packages deployment with dependency management takes package manager.

So, I'm pleased to announce that InterSystems ObjectScript Package Manager available!

Why gj :: locate?

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?ignoreC... 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?

anyone know of a simple way to search a blob of text from a list of keywords in one fell swoop, without having to iterate through each keyword and perform an individual search? Ex. 

s keywords="This,blob,text"

s text = "This is a sample blob of text"

i text[keywords w "hit"

We have a Unicode installation of Cache'. A client wants to send us documents that will be machine-read and loaded, automatically. They want to create the documents in ISO-8859-1 ("Latin-1"). We'd need to convert the text to UTF8 for our system. I saw the documentation on the $ZCONVERT function, but I didn't see this option. How should it be done?

Thanks!

End Session programmatically

We have a background job that keeps an eye on our ongoing CSP sessions, counts licenses used and some other tasks. Question: If I know the session ID (something like "wuuZ2Gwgxw"), how do I (find and) end that particular session programmatically in ObjectScript - i.e., the equivalent of %session.EndSession=1 in the csp page code?

Thanks!

If you create your own Language Extensions to Object you mostly have to find the
proper %ZLANGC00 or %ZLANGV00 or %ZLANGF00 and add the extensions manually.
A few utilities do it already automatically (ZPM, ZME, ..)
This utility allows you to add your extensions programmatically. (eg. at first run, or during installation)
I found this quite useful for my Docker-based demos as it all happens at the start time.

Background: We have our own SQL map that predates InterSystems'. A program writes an XML file for each table map class as $system.OBJ.Export would. $system.OBJ.LoadDir loads the XML files into .cls files.

The reason is a long story, but we need to update parameter EXTENTSIZE (only) in existing classes. This does not seem to happen. As a test I used $system.OBJ.Export to make an XML file and edited EXTENTSIZE in the two places it appears in the XML:

Hi Developers!

Recently we released the updated version 0.1.3 of ObjectScript Package Manager (ZPM) which comes with the support of simplified ObjectScript sources folder structure.

What 'simplified' does mean?

Before 0.1.3 ZPM expected the following structure:

/src

---/cls  - for ObjectScript classes

---/cls/package_name/class_name.cls

---/cls/package_name/class_name2.cls

---/mac - or Mac ObjectScript routines

---/mac/package_name/mac_routine.mac

---/mac/package_name/mac_routine2.mac

---/inc - for ObjectScript macro include files.

---/inc/package_name/include_file.inc

Hi Developers!

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.

Let's go!

Tips for debugging with %Status

Introduction

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).

Terminal Multi-Line Command Editor

The Command extension enables the execution of Multi-Line Commands from Terminal prompt.

Terminal Multi-Line Input with Edit, Insert, Delete, Print extension for IRIS and Caché
IRIS and Caché have just single command lines in terminal available
This Multi-Line Commands Editor also will execute the Multi-line Commands.
In addition, it is independent of access to %SYS and can be installed in any namespace

Special thanks to @Jeffrey Drumm  who inspired me to this and supported me as beta-tester.

SQL for ^ERROR Global
This is a coding example working on Caché 2018.1.3 and IRIS 2020.2 
It will not be kept in sync with new versions 
It is also NOT serviced by InterSystems Support !

Standard error logs in IRIS / Caché / Ensemble are written global ^ERRORS.
As this piece dates back some decades back to previous millennium its structure
is far from the typical SQL storage structures.

Making the most of $Query

I ran into an interesting ObjectScript use case today with a general solution that I wanted to share.

Use case:

I have a JSON array (specifically, in my case, an array of issues from Jira) that I want to aggregate over a few fields - say, category, priority, and issue type. I then want to flatten the aggregates into a simple list with the total for each of the groups. Of course, for the aggregation, it makes sense to use a local array in the form:

agg(category, priority, type) = total

Such that for each record in the input array I can just:

Hey everyone.

I have a process where I create a new %Stream.FileCharacter object, specify the filename (including it's path), write data to the stream, and then save. However for some reason, if the user account does not have write access to the directory, the %Save method is still returning true even though it was unable to actually write the file to the folder.

The location is a UNC path, and I'm wondering if this is tripping me up?

I have  a SQL query that I want to run against MS SQL from cache ensemble using the SQL outbound adapter. If I run this query direct from MS SQL Studio it take about 7 seconds MAX and returns about half a million rows. The row only contains one column it is a number all same size and if I run this query in the production in ensemble it takes for ever the production finishes without getting the response back. The same query run in cache outside the ensemble environment writing results to a file it returns results taking about 3minutes to complete.

I had a challenge recently where I was asked to parse and iterate JSON to find a patient that has a forename = "Bill" and try to make the function that iterates through the code re-usable.

Being working in Healthcare there isn't much experience or demand for parsing JSON, as most of my work is HL7.

I took this on using the documentation and worked out a way to parse the JSON (see posts below for code and source data).
