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.
I am familiar with $TEXT which can get you any line in the current routine provided you know the offset. For example, $T(+1) will get you the first line of the current routine at the run time. In the same vein, how do I reference the current line number/offset at the run time? Something like $T(+$CURRENTLINENUMBER) where $CURRENTLINENUMBER is not yet known to me function. The sample below would write 3 as the line number.
InterSystems Certification is developing a certification exam for InterSystems IRIS Developer professionals, and if you match the exam candidate description given below, we would like you to beta test the exam.
I am trying to write some code that takes in a string and does a serverside transformation of it to find embedded URLs and replace it with clickable links. I found the following regex for Javascript which is rated highly on StackOverflow;
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?
I have a list property that I query from the database to get the values contained in that list using $LISTFROMSTRING() when the list is returned the list values contain a rectangle like character similar to when you copy past something to the Terminal and it has a preceding space .The problem is I need to compare those values to other values and they do not match because of this value I have tried to use $EXTRACT(value,*W) and *P but this is not striping the preceding character how do I get rid of this character any ideas please.

In the sample below, an image file is encoded into a Base64 string in a class property, saved, decoded again with Base64, and restored to another file.
【Usage class】
Class User.test Extends %Persistent
{
Property pics As %GlobalBinaryStream;
}
I'm doing a REST service for integration between 2 systems. The system that invokes me expects a response object where only one of its attributes changes. It could be something like this:
If you define a Persistent Class / Table the class compiler generates for you an appropriate Storage definition. A different option is to define a SQL mapping for an already existing Global storage. This has been excellently explained already in a different series of articles. The Art of Mapping Globals to Classes 1 of 3
During my search for a snapshot of a persistent object, I met a feature that I would like to share as it could be useful in some special situations. My trigger was to have a before- and an after-image during unit testing.
Hi! I've been fiddling with linked tables to get data from other servers, and I encountered a problem that I'm curious about. Maybe I'm not using these tools as intended or there's more going on, so I'm asking here.
I'm running a query on linked table A, something simple like this:
Today's challenge is about decompressing input that is compressed in an experimental format. In the format, markers indicate how much time a number of characters need to be repeated.
On a persistent class, I have defined an %OnNew method that validate some properties with appropriate status code for each kind of error.
Question is: how do you catch the specific error when %New is called on this class?
Surrounding %New method with a try-catch not seems to work.
In reviewing the documentation found here, it states that there is an Attributes property. Since this is an array, I was wondering how I would go about traversing through the array to review what attributes are available on the file.
I must be missing something. We have done encoded PDF's in the past with the Encoded PDF in OBX.5.5. When I have used this code in the past I was only working with 1 OBX, but I have a case where I am having multiple OBX's and having to loop through them and I am renumbering the outbound OBX.
I am trying to do a basic read file of HL7 messages. Need to count how many FT1 segments are there in each file and how many messages are in each file.
Any help will be appreciated. I have the stream object.
Just need to loop through the stream and get the info in some way.
Background: We have our own SQL map that predates InterSystems'. A program writes an XML file for each table map class as $system.OBJ.Export would. $system.OBJ.LoadDir loads the XML files into .cls files.
The reason is a long story, but we need to update parameter EXTENTSIZE (only) in existing classes. This does not seem to happen. As a test I used $system.OBJ.Export to make an XML file and edited EXTENTSIZE in the two places it appears in the XML:
