#Code Snippet

8

Code snippet is a programming term for a small region of re-usable source code, machine code, or text.

I'm aware of two ways to get list of files in a dir:

set dir = "C:\temp\"
set rs = ##class(%File).FileSetFunc(dir, , , 1)
do rs.%Display()

and:

set dir = "C:\temp\"
set file=$ZSEARCH(dir_"*")
while file'="" {
   write !,file
   set file=$ZSEARCH("")
}

Yet they bot return only files and directories in a current directory, but not files in subdirectories.

I suppose I call one of these recursively, but maybe there's a better solution?

Drawing boxes

Hello, Community!

Here's an interesting task I found on the Internet.

Problem description

Write a method that would draw a box of a specified size.

The goal is to write the shortest method.

Here's a method signature (it can't be modified):

ClassMethod main(s As %Integer = 10)

And call sample:

>do ##class(ITPlanet.Task4).main(5)
#####
## ##
# # #
## ##
#####

>do ##class(ITPlanet.Task4).main(10)
##########

Hello,

First of all; thanks for your time reading this post, and thanks for your answers and help. I am really grateful.

We have the following need: Send a DICOM Find Document to get the complete list of a patient's studies from an Outbound System, which we simulate with the tool called "dcm4che" specifically with these two commands:

1º.Initialize a DICOM database in simulator. We will use this database to run queries using DICOM C-FIND commands:

$CASE For Long Stories

Hi, Community!

$CASE is a fine syntax sugar for "Ifs" with one-line/one-word expressions, like in docs:

SET daynum=$ZDATE($HOROLOG,10)
  WRITE $CASE(daynum,
              1:"Monday",2:"Tuesday",3:"Wednesday",
              4:"Thursday",5:"Friday",
              6:"Saturday",0:"Sunday",:"entry error")

But if my expression for a current case is a multi-line business logic? Can I use "{}" somehow or better go with "IF" instead?

Hello.

For debugging purposes I sometimes need to display stack information to the current device or save it (to a global for example).

There is this snippet offered in documentation:

ClassMethod StackToDisplay()
{
    For loop = 0:1:$Stack(-1) {
        Write !, "Context level:", loop, ?25, "Context type: ", $Stack(loop)
        Write !, ?5, "Current place: ", $Stack(loop, "PLACE")
        Write !, ?5, "Current source: ", $Stack(loop, "MCODE")
        Write !
    }
}

And to save stack to a global there's always an exception method:

I have a requirement to update the Ensemble Host Settings Programmatically. Mainly the "AlertOnError,QueueCountAlert,QueueWaitAlert,InactivityTimeout" settings.

I used Ens_Config.Item (persistent) class to get the settings (list object) and then update it. But for some of the Business Host's, I dont see the above settings in the table, but present in Settings of that particular Host in Ensemble Management Portal. So my logic is not working.

Handling Errors

I have a case where our EMR is sending data, but not all the values needed for the Ancillary are valued properly and causes that message to error/halt processing on the Ancillary system, not ideal but its what they do. I would expect them to still process the message except that 1 field, but they don't.

I want to add validation to make sure certain fields are valued correctly for the Vendor.

So I add some statements to take those items that don't pass this validation out to a batch file with headers.

Standardizing Error Logging

I have been tasked with creating a class that will handle error logging in a consistent manor for an application I am working on. The need is to have all variables in the calling method logged along with some other information.

The example given was zwrite which is exactly what I need, however, I somehow need to capture the output of ZW and put it into a database table. Any easy way to capture this data? I was able to dump ZW to a file, but that is not ideal.

Any help is appreciated!

Operators as Variables

We have the need to write a function that can loop through say a field in an OBX segment within HL7 and compare it to a string passed. Is it possible to have the user enter the Operator ( >,<,=,<>) as a variable inside Cache object script? Does anyone have any examples they can share?

Hi all, I am new to IS Objectscript and I would appreciate some assistance regarding this.

I am trying to find out how to count the number of elements within a dynamic abstract object and I am having some trouble using the size method.

Here is the code below:

The key value pairs are originally in JSON and I would have converted it in to an object for use.

Hello Everyone,

I was wondering about the best way to initialize several variables, or several lists of variables.

Would it be better to write it like:

set (var1, var2, var3) = "value1"
set (var4, var5) = "value2"
set (var6,var7,var8) = "value3"

or

set var1="value1", var2="value1", var3="value1", var4="value2", var5="value2", var6="value3", var7="value3", var8="value3"

Hi Team,

I have a requirement to delete the Ensemble interfaces , as per User request. I would like to write a routine for that and once I execute, it should remove the interface components through code.
Could you please provide code samples for the following actions ?

  • Deleting an individual rule from a rule class
  • Deleting a class from Ensemble
  • Deleting a Host (Service/Operation/Process) from the Production.

Appreciate the help.

Thanks,

Replacing character groups

What's the best way to replace character groups?

I want not to remove character groups as $zstrip does but to replace them with whitespaces.

$translate needs explicit character list.

Effectively I want to remove any characters besides letters, numbers and a small (known) subset of punctuation characters, replacing everything else with whitespaces.

Hello,

We would like to learn how would you approach this task.

We would need to check every day a set of folders which are outside our server (in fact we could see them as if they were "inside" the server), then we need to check for modified or created files in the last day, and move all the ones which match the criteria to just one folder in our server.

We have thought about doing the following:
