#ObjectScript

14

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.

Here is what is currently used.

..CurrentDateTime("%Y%m%d%H%M%S")

The format is not the issue.

I need to make it our current time as it is five hours ahead.

How can I access the header property of either of these.

Or, if I can't do that, subtract five hours or the equivalent time in seconds.

example, if I receive 20201224161922, how can I make it 20201224111922?

Thanks,

Jonathan

Embeddedpy-bridge: A Toolkit for Embedded Python

Overview

Embedded Python is a game-changer for InterSystems IRIS, offering access to the vast Python ecosystem directly within the database. However, bridging the gap between ObjectScript and Python can sometimes feel like translating between two different worlds.

Hi developers!

There is a very neat variable in IPM ${ipmdir} that lets packages be installed on a particular IRIS server and ensures that the data and resources they bring don't mess around as ${ipmdir} variable during the installation transforms into:

iris installation dir/ipm/package_name/version/whatever_you_install_here

It is very convenient, e.g., to bring some data and resource files that can be useful during the installation setup, e.g., via FILECOPY. Indeed, suppose you bring some csv_file, e.g. titanic.csv via FILECOPY as:

<FileCopy Name="data/titanic.csv" Target="${ipmdir}data/titanic.csv"/>

or even the whole folder of data in the source code repo into the package:

<FileCopy Name="data/" Target="${ipmdir}data/"/>

And in the case of Iris in Docker it resides in:

/usr/irissys/ipm/package_name/1.0.0/data/titanic.csv

This is all great, but is there any way for the installed code to determine the location of the data files? It'd be neat to let the installed app know somehow where is the data that came with it? Could it be the method in the IPM client that will resolve ${ipmdir} for the app?

Hi developers!
Happy holidays!

In ObjectScript there is neat option to log errors - call Log() method of an exception intance, e.g.:

ClassMethod MyMethod() {

Try {

w 1/0

}

Catch e {

do e.Log() // logging error in the app log

write "the error happened: "_e.DisplayString()

}

}

Is there anything like that for Embedded Python? e.g:

ClassMethod MyMethod() [Language = python] {

 try:

   print(1/0)

 except ZeroDivisionError as e:

   // how can I log e into IRIS App Error Log here?

   print("Caught exception: " + str(e))

}

Any ideas?
