Hi Community!

I have very good news for the developers, who are using GitHub to host projects with InterSystems ObjectScript. GitHub introduced the support of InterSystems ObjectScript this week!

How does it work?

Now all the .cls files in your repository are considered as InterSystems ObjectScript and highlighted according to the language rules of ObjectScript. For example WebTerminal, Samples-Data.

I have a custom process that is parsing HL7 and inserting it into a table. Periodically the inserts fail with # due to error: ERROR #5803: Failed to acquire exclusive lock on instance of....

Traditional databases would wait until the lock is removed then do the insert, but cache fails. I'm sure it's my coding approach.

How can I work around this? A Try/Catch loop?

Thanks in advance.

hi, i am new to Studio and also new to objectscript, but i am not new to programming and

want to implement some synonymfunctions e.g. LOCATE should be used as InStr (.. like in much languages ;o)

more generally spoken, i want to implement a library for my string routines BUT of course i want an need autocomplete.

defining a macro $$$InStr does no autocomplete when i type $$$In<CTRL-SPACE>

example: my lib is called STRINGS and the functions are: InString, Split, ...

Hello,

I assume there is a simple explanation for this, but I do get <OBJECT DISPATCH> error, when I am trying to set a global to a value.

My example is huge, but I reproduced it using Samples namespace:

First I delete the Title from ##class(Cinema.Film) - 3

Secondly:

SAMPLES>s ref=##class(Cinema.Film).%OpenId(3)
SAMPLES>w ref.Title

SAMPLES>set ^AK(1)=$G(ref.Title)

SET ^AK(1)=$G(ref.Title)
^
<OBJECT DISPATCH> *Property 'Title' in class 'Cinema.Film' must be MultiDimensional

Hello all,

I have a Recordset object which contains data from a table "XYZ".

Currently i use this object to extract data using %Get(COL1,COL2...) in a loop and than pass it to a function which inserts the data into another dynamically created Table "ABC" for each record. This takes a lot of time when 100's of records.

Is there a way i can directly copy a RecordSet to a dynamic table without looping through..?

Something like copy Recordset (COL1,COL2..)--> "ABC"

Thanks,

Jimmy

Hi all,

I am trying to create multiple tasks all in a single task.

For instance MyApp has three tasks.

One to send a email if a limit is exceeded = MyApp-check-credits

One to purge files = MyApp-purge

One to auto delete files = MyApp-Del

I would love to get all tasks MyApp-check-credits, MyApp-purge, MyApp-Del into a single parent task called MyApp-AllTasks.

Is there anyone that could give me guidance of how to complete this it would be much appreciated.

Tortoise GIT Setup

We are currently trying to implement TortoiseGIT into Cache Studio as per the following Github project

https://github.com/intersystems-ru/cache-tort-git

Our architecture is as follows:

- A server with Ensemble installed on

- Team of several members connect to the server and perform their code build

TortoiseGIT was installed on the server, however, should the REPO location be:

- on the server itself (as a shared path)?

In the previous parts (1, 2) we talked about globals as trees. In this article, we will look at them as sparse arrays.

A sparse array - is a type of array where most values assume an identical value.

In practice, you will often see sparse arrays so huge that there is no point in occupying memory with identical elements. Therefore, it makes sense to organize sparse arrays in such a way that memory is not wasted on storing duplicate values.

In some programming languages, sparse arrays are part of the language - for example, in J, MATLAB. In other languages, there are special libraries that let you use them. For C++, those would be Eigen and the like.

Globals are good candidates for implementing sparse arrays for the following reasons:

In our table, we have a column cities, which has a filter which displays the cities of a state depending on the state

For simplicity let's assume we have a page

Property State As %String = "CA"

Our filter should run this query to show all cities of state ca
