#ObjectScript

Hello everyone
I use cache script, I would like to know from you if there is any function or class in the cache where I can get the start and end date of a given month:
Example: What is the first and last day of the month of February 2015.

Grateful.

I have an ObjectScript class with a Log property of type %Stream.GlobalCharacter.  I need to search the end of each of the logs - is there a way to extract the last 10 lines of the Log stream for each object via SQL? Or is my only option to write an ObjectScript routine to walk the table and inspect each Log property one by one?

Thanks!

As you know ObjectScript has no FOREACH system command nor system function.
But it has a wide room for creativity.

The task is to loop over a global or local array and do something FOR EACH element.

There are 2 possible solutions:
- creating a macro that generates the required code sequences
- creating an Extended Command to perform the action.

Hi everyone.

This is a full example how to use a %ScrollableResultSet for results pagination using %DynamicQuery:SQL and build a JSON response including page details.

Feel free to use, share, comment or improve it.

Kind Regards

Hi,

I'm processing POP3 emails using the standard EnsLib.EMail.InboundAdapter adapter and %Net.MailMessage. I'm basically processing documents that are attached to received emails. This works fine if the document is simply attached to the email itself. But some systems are sending documents that are attached to an attached email which has content-type = message/rfc822.

How do I get the attached file from the attached email?

Our client is a UK-based company with subsidiary operations in the USA, France, Germany and China.

After linking in Oracle Table with Field Column's Data Types of NUMBER, my updates into these table fields are resulting in data that is being rounded to 2 decimal places. I insert a record with 1234.1234 and 1234.12 is stored.

It appears Cache xDBC might be manipulating my values prior to sending to Oracle. Is there a setting or system parameter that is controlling this? If so, is there a way to relax this from occurring so the values I send are being stored in Oracle with the same values?

Hi developers, 

We have just published an update to the Deltanji version control extension for Visual Studio Code.

When used in certain Deltanji workflows, triggering an automatic checkout on first keystroke could result in the developer working on an outdated copy of the code and only being notified of this later when saving their changes. In order to prevent this from happening checkout now reloads the document immediately. 

Error messaging has been improved in two areas - when attempting to cancel code that is not checked out, and when trying to register new code onto a withdraw system. 

We have also improved interoperability between the Deltanji extension and the InterSystems ObjectScript one, as well as its handling of multi-component objects.

If you're already a user of Deltanji then your extension with automatically update. You can find out more information on Deltanji and the latest release here. 

Hi developers!

Just want to share an old but always relevant best practice on namespaces changing @Dmitry Maslennikov shared with me (again).

Consider method:

classmethod DoSomethingInSYS() as %Status

{

set sc=$$$OK

set ns=$namespace

zn "%SYS"

// try-catch in case there will be an error

try {

// do something, e.g. config change

}

catch {}

 zn ns    ; returning back to the namespace we came in the routine

return sc

}

And with new $namespace the method could be rewritten as:

classmethod DoSomethingInSYS() as %Status

{

set sc=$$$OK

new $namespace

set $namespace="%SYS"

// do something

return sc

}

So! The difference is that we don't need to change the namespace manually as it will be back automatically once we return the method.

and we don't need try-catch (at least for this purpose) too.

I have been working within Objectscript for a few months and I am seeking assistance today because all of the help files within the docs.intersystems.com domain are currently down and they wont be back up until next week. (I raised a special ticket for this) 

Hi folks!

Want to share a lifehack with you on ObjectScript highlighiting withing VSCode for script files.

Script files are just files with lines of ObjectScript that we feed anywhere, e.g. into IRIS during Docker baking procedure.

Typical usecase - here is the Scriptfile

here is the Dockerfile where we feed it.

And here is how it looks like usually in VSCode:

Coudl be more beautiful, right?

Hi,

How to check if data string contains Unicode characters?

Thanks

I have a routine tag that takes an argument and I want this argument to be an array reference.  So I try something like:

do mytag(.myarr)

The mytag tag, adds subscripts to myarr.

When I evaluate myarr after the tag call, only the subscripts passed in are retained in myarr.  The subscripts added by mytag are missing.  Is there a way to pass an array so it will behave the way I want it to?
