InterSystems ObjectScript extension for VS Code, version 3.0.1

Am also asking this question on the extension's GitHub page: Request textDocument/documentSymbol failed. Error: name must not be falsy · intersystems-community/vscode-objectscript · Discussion #1530 - but suspect more eyes will see it here, which might help gather additional information.

Tried to compile some legacy ObjectScript code via Import/Compile in VS Code using the vscode-objectscript extension. Getting an error, and the content of the file is left changed on the filesystem simply by being compiled.

Hello Community,

When I compile the Sample.User class for the first time, and include an ObjectGenerator method intended to run certain logic during each compilation, it throws a <CLASS DOES NOT EXIST> error. However, recompiling the same class works as expected.

I understand this happens because the class hasn’t been fully compiled yet during the first pass. To overcome this issue, are there any specific callback methods available that can safely be used after the class is fully compiled?

Hi everyone,

I’m working with an existing InterSystems IRIS server that hosts several web applications and namespace-specific code and data. I’d like to reverse-engineer the current environment into a %Installer.Manifest file so I can store it in Git and manage its changes.

My goal is to:

• Track the application setup and configuration in version control
• Rebuild environments consistently (namespaces, CSP apps, security roles, etc.)
• Possibly automate deployments later on

I have a class with a projection that creates some persistent classes (chunks) and a non-persistent "Daemon" class that I want to have running in the background, doing some processing. The daemon needs to look at the "chunk" classes, and I want it to be simple to start the daemon -- I am currently calling the daemon's start method at the end of the CreateProjection method. When I do this, I get a <CLASS DOES NOT EXIST> error from the daemon when it tries to query against one of the chunk tables. But, if I add a "HANG 5" at the beginning of the daemon start method, this runs fine. I am assuming

I was thinking about how to create a new parameter in a method, similar to Output or ByRef...

What documentation can I read to learn more about this?

I want to create a parameter customized.

The first developer previews of InterSystems IRIS^® data platform, InterSystems IRIS^® for Health, and HealthShare^® Health Connect 2025.1 have been posted to the WRC developer preview site.  Containers can be found on our container registry and are tagged latest-preview.

These developer previews include the feature to migrate to IBM "Open XL C/C++ for AIX" 17.x compiler ensuring compatibility with future AIX builds as older compilers approach end-of-support. This migration focuses on the aixopenssl30 target, supporting SSL3 on AIX 7.2 and 7.3.

I'm experiencing an issue while compiling code in Visual Studio Code with "cuk" qualifiers.

When I try to compile, the following message appears after a while:

In VSC, the "cuk" qualifiers are always used as default and the following message is shown in the Output panel of VSC when a compilation is successful:

I'm unsure if it is possible to replace the cuk qualifiers with something else.

The issue doesn't occur when compiling the same class in InterSystems Studio, where, in this case, the qualifiers "cuk /checkuptodate=expandedonly" are used as default:

Hello,

Since version 1.93 of VS Code, the “import and compile” process has been very slow (more than an hour).
Have you encountered this issue and do you know how to resolve it?

Thank you,

Maxime

I created and then compiled a routine using the %Routine library 

s routine = ##class(%Routine).%New(fileName_"."_extension)
d routine.Write(parsedRule)
//s status = routine.Save()
s status = routine.SaveStream(,.refresh)
if ($$$ISERR(status)) throw status

Now the routine compiles successfully and as a result it is saved on the database.
I can now use from anywhere:

set r = ##class(%Routine).%New("myGeneratedCode.mac")

w r.SizeGet()

Is CR/LF changes to DTL files edited/committed to git via VS Code a known issue?

We had an issue with exporting files from one server and importing on another, using XML code exported from Studio: ERROR #6301: SAX XML Parser Error. Turns out that issue was down to CR/LF changes made when transferring the XML from one server to the other.

Hi folks,

We are in the process of migrating from Ensemble to IRIS.

After the migration I would like to find all usages of deprecated classes and methods in all of our code. This is to align with the changes in package like %SYSTEM.SQL for example.

Is there an easy way to do this, or maybe a tool that can assist?

Thanks.

I have a class with two methods

Class Foo.Bar
{

ClassMethod Helper()
{
// do something
}

ClassMethod Generated() [ CodeMode = objectgenerator ]
{
do ..Helper()
// do something else
}

}

Since the method Generated is run before the class is compiled, the call to do ..Helper() fails. Is there a way around this other than manual inlining?

I'm trying to learn M programing for an Epic db class prerequisite. They said to download the IRIS Studio software to do the testing. I'm having a very difficult time finding information the language. I'm trying to run some examples that Epic has provided (like in below) but the compiler complains that it isn't valid. Of course, it doesn't tell you why it isn't valid.

r !,"Enter the hour: ",hr  
 r !,"Enter the minute: ",min 
 r !,"Enter the second: ",sec 
 s Mtime=$$ConvertToMTime(hr,min,sec)
 w !,"Equivalent M time: ",Mtime  
 q
ConvertToMTime(h,m,s)
 q (h*3600)+(m*60)+(s)

I get these errors:

Hi, please let me know where i find details on Objectscript internal implementation - is it an interpreted language ? - compiled into binary code (how - which compiler/toolchain ?) ? - support of LLVM ? thanks a lot Frank

*** updated from a comment as original question may not have been clear**

To clarify my question this is the library property helper class Library property helper when you look at the documentation for computed from documentation here Computed documentation

ClassMethod FullNameComputation(cols As %Library.PropertyHelper) As %String
{
    return cols.getfield("FirstName")_" "_cols.getfield("LastName")

Hello dear developers,

I am currently doing an internship and learning about InterSystems IRIS and ObjectScript and have downloaded and installed the community version of IRIS.

I have not made any changes in the Management Portal.
In Visual Studio Code I have loaded the InterSystems ObjectScript Extension Pack.

If I now want to compile a file, VSC throws an error:
"ERROR #16006: Document name 'x.csp' is invalid"

The name of the file is "index.csp"
This error also appears when I try to compile other files.
I have noticed that the first 4 characters of the name are always missing.

Occasionally, in VSCode, compile errors stop displaying. I'll be getting errors on compile all along (expected, and it compiles while saving using CTRL+S), until they'll suddenly stop. I haven't found any solution, including restarting VSCode and restarting my user session in Fedora. I'm running IRIS locally on Fedora and running VSCode also on the same machine. The only solution I've found is to restart IRIS. It's a solo dev environment and relatively small, so restarting isn't anything but an annoyance.

Are there any known bugs around this or any other solutions?

How to understand what's wrong with compilation if the compilator just hides errors?

Compilation started on 05/15/2023 15:58:11 with qualifiers 'cuk'

Detected 1 errors during compilation in 0.003s.

Compilation started on 05/15/2023 15:58:51 with qualifiers 'cuk'

40 errors, and what do I have to do with this so valuable information?

In elder versions of IRIS/Cache numeric overflow was detected during the syntax check:

RITE sW$COMPILE(s,0,e),!! ZWRITE e
       ^

while in IRIS 2022.1 it is not:

Exported contents of a namespace on one server (classes, include files and lookup tables). Importing that code into a newly created namespace on another server. Both servers Ensemble 2018.1, same build. Export was via InterSystems Studio. Export is around 18Mb in total (XML file sizes).
When importing and compiling on the new server, getting errors as below - with #6301: SAX XML Parser error prominent - on a number of the imported files, all containing data transformations or business processes.

Hey all,

I have been creating a class to handle file encryption by using GPG keys. I pushed my code out today and my encrypt and decrypt methods weren't working. About a half an hour later in troubleshooting I found out that it needed to be a syntax change. My method has three parameters to it. Examples below:

This is how I was calling it in the test system with no issues:

do gpg.Encrypt()

This is how I was having to call it in my production system to work with no issues:

do gpg.Encrypt("","","")

1.Background

        1.1 I met a few project that their interface servers were crashed. Cutoms wanted resume server as fast as we can. their servers are running at lan,and they can't use git,there are some namesapce in the server running different service,and usualy there is only one server.

        1.2 In the message,it has property in type of characterstream,as you know,the message search page doesn't support filtering with  property of characterstream,so it's so hard to find the messge you want.

        1.3 Other workmate may update the code on the server,and mybe their is something wrong.

It's well-known that Studio and probably VS Code have options to expand ObjectScript commands and functions to their full names (Ctrl-E and Ctrl-Shift-E in Studio), therefore some methods to accomplish this should exist. The question is: how to do it programmatically?

If I'm using an objectgenerator, is there a way to check the compile flags and have it behave differently based on which flags are set?

And as a tangent, is there a list somewhere of what compile flags there are?

Hello programmers !!
I'm learning COS and Ensemble and also I started to work with this technology and I did set up vscode to program,
but I don't know how to set up the vscode terminal for COS.
Could anyone help me?
I'm a beginner with this technology

When overwriting the Read method (that has a %CacheString return type) on a new class that inherits %Stream.FileCharacter class, returns an error about incorrect return type, must be Binary, even if it matched the real signature.

Looking at the compile global information we can see:

^oddCOM("%Stream.FileBinary","m","Read",42)="%Library.Binary"

After further investigation we realise that there is a generator method looking at the OdbcType class definition.

Setting LONGVARCHAR results in:

^oddCOM("User.CStream","m","Read",42)="%Library.String"

We found out recently that when compiling an objectscript class that has a java projection, using the -d flag, it ignores it for the projection part:

After talking with intersystems luckily the've provided a solution that will be included in the next release:

We're upgrading to IRIS 2020.1 from Ensemble 2018.x.

I have a lookup table class that compiles fine in Ensemble but in IRIS causes the following compilation error: "ERROR #9101: Global name 'HH.LookupLabResultsToPhysiciansD' for 'IDLocation' is too long, must be no more than 31 characters in length."

Is this length limitation a new restriction or could I have done something years ago to increase the maximum character length.

Thanks,

Jim

Hi, Community!

Please share your experience on code deployment on production site. Do you compile ObjectScript on Production? Is it OK? 

Or you only compile on Test site and copy cache.dat to a Production?

In my previous article, we reviewed possible use-cases for macros, so let’s now proceed to a more comprehensive example of macros usability. In this article we will design and build a logging system.

Logging system

Logging system is a useful tool for monitoring the work of an application that saves a lot of time during debugging and monitoring. Our system would consist of two parts:

• Storage class (for log records)
• Set of macros that automatically add a new record to the log
