#Compiler

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?

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

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"

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

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

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.

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.

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?

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'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

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

hi-

Can someone give me an example of how to JOB a class method that requires an array of values to be passed to it by reference.

This is what I tried, but am getting compile errors because of the .params

job ##class(%SYSTEM.OBJ.FM2Class).All(.params)::5

Any thoughts on how to accomplish this, the simplest way. I would like to avoid writing all of this to some global and having to write some wrapper to pick it up and then call the class method, which I certainly could do. but is this the only way to do it?

How do I compile a file through the command line?

I am generating a very basic csp page in a bash shell, it is generating fine and displays what I want to see as long as I go into studio and compile it . This defeats my purpose of having the page and I am having no luck figuring out what I am doing wrong. I think the issue has to do with the file not being included when I compile from command line.

Ver is 2017 running RHEL 7

From command line I see

TST 3f2>DO $SYSTEM.OBJ.Compile("csp.vvmaccessnewrds","h")

When dealing with a support issue of one of our Deltanji source control sites this week I learned that if you're using InterSystems versions earlier than 2018.1 on Unix-type platforms it's possible that a class you export in UDL format will subsequently fail to import. So I'm posting this information here in case it helps other folk.

First, my $ZVERSION:

Cache for OpenVMS/ALPHA V7.x (Alpha) 2010.1.6 (Build 952_2 + Adhoc 17754) 3-JAN-2018 14:32:54.07

Second, my issue:

I believe my current villain is “incremental compiling.” I was able to compare early compile output with later compile output:

Compilation started on 04/10/2019 10:46:32 with qualifiers 'cuk'
Compiling class UnitTests.Task3496 incremental compile detected
Compiling routine UnitTests.Task3496.2
Compilation finished successfully in 0.800s.
