#ObjectScript

20

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.

Documentation.

I need to automate the handling of usernames passwords, serverNames etc for use in the sending and receiving of emails, logging into SFTP servers etc etc for use within COS code
To manage external passwords we could use LastPass or any other proprietary password loggers, but I need to be able to call them as part of the automation (COS code) and occasionally visually look them up to "remind" the staff of their passwords.

any suggestions as to the best class data constructs to handle this scenario. Should the whole table be encrypted, only the passwords etc.

Code migration using VSCode

I am fairly new to using VSCode. I have used VSCode to create some files on our Test Server, now I need to move them to Production.

Looking through the VSCode extension documentation, maybe I missed it but how to I migrate code from one workspace to another. In Studio I was use to exporting the code into an XML and just being able to import it on the Production server version of Studio.

Thanks

Breaking a string into words

Is there any ObjectScript or a basic function that takes a string and separates it into words + punctuation/spaces array/list? Just not to reinvent the wheel. Say, process "It is a test, after all" into "It", space, "is", space, "a", space, "test", ", ", "after", space, "all". Or something to that effect.

Hello!

I wonder if anyone has a smart idea to extract an XML fragment inside a text document (incoming from a stream)?

The XML fragment is surrounded by plain text.

Example:

text...........
text...........
<?xml version="1.0" encoding="UTF-8 ?>
<Start>
...etc
</Start>
text...........
text...........

The XML is not represented by any class or object in the Namespace.

The XML can look different from time to time

Hello fellows, I need you wisdom.

In my organization we code in ObjectScript and .int everyday. When I joined nobody knew barely nothing about classes and their use was almost only for storage definition purpose. During my self-learning in caché I discovered the object oriented programming and class developing was possible in caché and started to code in .cls . Being something self-taught, I may have some basic doubts I'd have missed in my documentation readings.

Timing of Database look up

We use a lot of external MS SQL calls to look up numerous things when it comes to HL7. I am running into an issue where the outbound calls are queued but the message is sent onto the next process before it gets a response. How do I get it to wait till the response gets back from the MS SQL call before sending it onto the next process?

Below is a screen shot of what I am trying to explain...Select Research Study executes at 8:33 the message is sent to the next process at 8:34, but the response of the MSSQL call doesn't come till 9:31.

I got a problem to resolve, to sum it up I need to extract a function body from a JS file with cos.
I already got the JS code in a string and the function name but I'm kinda stuck as to how to get my function body, I already tried a few things (regEx, counter bracket) but there are comment and strings that block them from functioning. Is there a javascript parser or a good way to do it except by creating a javascript parser?

Hi,

I have a situation where I write a character stream to a file. The file content gets signed and the signature is sent to a service provider together with the file content.

The signing is done using openssl.

This works perfectly on a dev PC, which is runnning Windows and has a little-endian architecture.

The problem is as soon as I do this on the server, which has a big-endian architecture, the signed value is incorrect according to the service provider.

The content is signed using RSA SHA256 with PSS padding.

I have a serial object:

Class EmbedObj Extends %SerialObject

which is stored as a property of another object

Class ContainerObj Extends %Persistent

Property InnerObj As EmbedObj;

Property Foobar As %String;

Question:

From within the context of an instance of EmbedObj, how can I navigate to the containing instance of "ContainterObj" and find that value of its Foobar property?

Hide or make routines binary?

Sorry, somewhat of novice here, but how is a mac or a routine created into a binary or is there a way to hide your routines so that no other user can edit them? Like remove source code and have an executable?

I would like to do this MAC and CSP pages

Hi,

My doubt is about the SQL Query in Caché:

I don't want to take all results from the table and orgainze them manually, for example: I have a table with 50 records, but I only want to select 10 records, being from tenth until the twentieth and this without knowing their IDs.

So, how can I do this, without losing performance, there is any way?

Good day, every process in my software is about to update 3 specific globals in row when the process is called to do some job. I need to guarantee that during updating of those globals with multiple processes there is only one process that is actually working with those globals. Moreover I need my globals unreadable if other process is in critical area.

Cache Ensemble

Hello,

Working on to learn very basic CUSTOM Business Service which sends to a EnsLib.File.PassthroughOperation.

But operation is not writing to File and erroring out (No Stream contained in StreamContainer Request")'.

How do convert the object to STREAM and wrap in the StreamContainer so the operation does not error and write to a file.

Thanks.

Was wondering if anyone had a simple way of calling ##class(Ens.Director).EnableConfigItem() within a Business Process or adding code to a Custom Service to start or stop the object?

The use case is that I have a Process that uploads a file into a external SQL table. When it is finished I want it to kick off another Service that does the processing of the data that it just uploaded. Once it is finished the response is sent back to the service and when the service receives the response from the process, I want to stop that service from running.

so...

Hoping someone can help.

I need to convert a timestamp from the following format (YYYYMMDDhhmmss e.g. 20160105125915) to UTC time in the same format.

I presume I need to convert it to the system format ( like $HOROLOG ) and then use something like ConvertTimeStampToHorolog or perhaps LocalWithZTIMEZONEtoUTC but not sure of the syntax.

Thanks,

Conor
