#Coding Guidelines

I have a class with a projection that creates some persistent classes (chunks) and a non-persistent "Daemon" class that I want to have running in the background, doing some processing. The daemon needs to look at the "chunk" classes, and I want it to be simple to start the daemon -- I am currently calling the daemon's start method at the end of the CreateProjection method. When I do this, I get a <CLASS DOES NOT EXIST> error from the daemon when it tries to query against one of the chunk tables. But, if I add a "HANG 5" at the beginning of the daemon start method, this runs fine.

Hello everybody ! 
My colleagues and I were wondering why the varstring class is hidden in the Intersystems documentation.
Is it "safe" to use ? We tried looking it up in the forum and it seems like it is used by other developpers. Is there anything we should know before using it ? 

Thanks!

Hi.
This is my first post on this forum; I've tried to open an issue on the official repo , but it seems inactive from more than a year, so I can't receive an answer from there.
I would like to know if someone use that extension and know how to use it when working server-side on an IRIS server.
I have no problem when coding on a file saved locally.
Thanks in advance

Hi folks,

We are in the process of migrating from Ensemble to IRIS.

After the migration I would like to find all usages of deprecated classes and methods in all of our code. This is to align with the changes in package like %SYSTEM.SQL for example.

Is there an easy way to do this, or maybe a tool that can assist?

Thanks.

Hello My Friends,

I have a problem with my script, In another code it works fine, but in this script It not display anything in InterSystems portal, when I try to debug, it gives the data, but why in portal it show nothing?

Can anyone help me please? Thank you

in Portal it show nothing

When I'm writing code in Intersystems Studio code completion is different than in VS Code. It would be greate if VS Code would react the same way on code completion .. This happens is studio

When I do this in VS Code it doesn't show the object but it shows ??  all possible items ?? 

We need to resize existing images already in %GlobalBinaryStream  to create thumbnails.

The requirement is also to use the method to resize new images that are uploaded.

Does anyone have a solution for this ?

Does any one could tell me how can I access the target properties from inside SQL in DTL Subtransform? For example, if I use the following statement:

SELECT ID INTO :target.SetIDPID  FROM firstlook.person WHERE  FirstName = 'Paul' - as said in documentation :

  SELECT Name INTO :target.Name FROM MainFrame.EmployeeRecord WHERE SSN = :source.SSN AND City = :source.Home.City

I get an Error: ERROR <Ens>ErrException: <PROPERTY DOES NOT EXIST>

But if I pass the value for a variable "SetIDPID" I can use it in a set action without any problem: 

SELECT ID INTO :SetIDPID  FROM firstlook.

I have created a Class method to list employees that are subordinated to a certain boss. But I don´t know how to relate the data in the way it was given to me.

For Example:

• ^Employee(IdEmployee) = Name

                  ^Employee(1) = "Jessica"

                    ^Funcionario(10) = "Rose"

• ^HistEmployee(IdEmployee, Date) = Salary^Job^IdEmployeeBoss

                    ^HistEmployee(10, 64628) = "3500^Secretary^1"

So, based on this seetings, Jessica is Rose's boss. But I don't know how I can make a relation between that string and the subscript. Can someone help me?

Hi! I am working on a project where I use record map to transform a flat file and split it into two output text file and in the future will need to split four output files.

I only want to use one  target business operations instead of multiple. Is there a way to set the output file and the target folder path in my business process class?

Any advice on how I can achieve this or is this possible? Thanks!

Hello everyone,

I have an issue with using "Open" function.

My goal is to execute a shell script with parameters like as:

/trak/FRXX/config/shells/transportIDE.sh "login|password|NOMUSUEL|PRENOM|NOMDENAISSANCE|1234567891320|199999999999999999999999|09%2099%2099%2099%2099|31%2F12%2F1999|242%20IMPASSE%20DES%20MACHINCHOOOOOOOOSE%20||99999|SAINT%20BIDULETRUC%20DE%20MACHINCHOSE|isc%24jhu|123456|123456798"" 2>&1"

But when some parameters are too long, I have a <NAMEADD> error.

Hello community,

Our organization is looking to expand our Coding Standards to be more in alignment with best practices.

I was wondering if the there are developers here that would not mind sharing any existing documents. Our scope would be this document be applicable to new hires learning Cache all the way up the chain.

Thanks in advance,

Hi community!

Is it possible generate HTML documentation to my project ObjectScript classes (.cls)?

In Java we use Javadoc to do it. Javadoc get class comments and java metadata information and when I execute javadoc -d doc src\*, I get whole html documentation to my classes. Has IRIS something like javadoc? Is it documatic? If yes, how can I use it?

I have multiple files with different columns, first 9 values are fixed, so i want to ignore the first value, and next 8 values i want to combine into one value using ^ sign

Current Format

|||||||||||^^||||||^^|||||||||||||||||
|||||||||||^^||||^^|||||||||||||||||||||||
|||||||||||^^|||^^||||||||

Desired Format

^^^^^^|||^^||||||^^|||||||||||||||||
^^^^^^|||^^||||^^|||||||||||||||||||||||
^^^^^^|||^^|||^^||||||||

Reading each line from the file use below code.

#dim line as %String = tInput.ReadLine(, .

Any syntax help, i want to check different msg types and then reach out to the value in that particular segment. Here is example, i want to get SSNNumber from a method. Trying to use NOTIN, and Lookup

Class Training.RulesFunctionSet Extends Ens.Rule.FunctionSet

{

ClassMethod getEmiratesId(pHL7 As EnsLib.HL7.Message) As %String
{
SET msgType = pHL7.GetValueAt("MSH:MessageType.TriggerEvent")
 

IF msgType NotIn "A39,A40,O01,O11,O09,R01" {
return pHL7.GetValueAt("PID:SSNNumberPatient")}

IF msgType In "A39,A40" {
 return pHL7.GetValueAt("PIDgrp(1).

Hello,

I work on deploying IRIS inside Docker container. I really like %Installer class can automate many steps. I want to establish an ECP connection to a mirror database and then define a remote database on the application server. I have already seen we can create local database and namespace in %Installer. What code is needed to establish ECP connection?

I have been looking into using abstract classes and methods. In other languages, if a superclass is defined as abstract, subclasses inheriting from the superclass will not compile until all abstract methods have been implemented in the subclass.
I have created the following classes to try this in Cache:
Class User.Music.AbstractClass [ Abstract ]
{

             Method testabs(inp As %String) [ Abstract ]{}

}

Class User.Music.AbstractTest Extends (User.Music.AbstractClass, %Persistent)

{    

           Method testabs(inp1 As %Integer) { w !!,"Input:",$g(inp,"undefined") }

}

When I compile User.

Hi all,

I'm wonder what could be the best way convert the sentence "Switch" C# into Cache code.

int caseSwitch = 1;

switch (caseSwitch)
{
    case 1:
    Console.WriteLine("Case 1");
    break;

    case 2:
    Console.WriteLine("Case 2");
    break;

    default:
    Console.

Hi everyone,

Are there any tools to check the code coverage and to do a lint check for cache object script? Developers will be working with HealthConnect (IRIS based)

Thanks.

I understand RecordMaps can be used to send delimited files through a production without custom coding. The data segments are delimited by tilde character followed by $Char(10) in Linux/Unix. When I test the same IO data in Windows, I have $Char(13) and $Char(10) instead of just $Char(10). I like to use just tilde character for record delimiter and ignore $Char(13) and $Char(10) between the tilde and the leading data of the next segment / record. Is this good idea or not if someone wants to generate classes will it override code? I believe in X12 schema it ignored leading control characters.

Hi,

I have a method that has multiple parameters and is normally used from other classes in ObjectScript. Most of the parameters have default values. Withing the server code that's perfect. In some areas I can call myMethod(,,"sometext") or myMethod(tVariab) and thats fine... I use it as it's required in each place.

But now I want to expose it as a REST service so I need to buld a kind of wrapper.

Hi guys,

I have never used regular expressions with caché object script before, so I've read through the documentation, but I am struggling with things that I'd like some help on.

My need is to identify specific html tags and transform them out to something else. Example:
I need to identify those guys in a wider string:
"<span style=\""font-family: '';font-weight: bold;\"" >BOLD TEXT</span>"
"<span font-style:italic;\" >ITALIC TEXT</span>"

And then they'll become:
"<b>BOLD TEXT</b>"
"<i>ITALIC TEXT</i>"

I started off by using this regex pattern https://community.intersystems.

Say I have a property in  a persistent class that stores list of colours and I would like to query that field and return  a list and be able to loop that list to get individual colours how will l go about achieving this I have tried something like this but its not working as expected

 &sql(SELECT colour INTO :colourList FROM favouritecolours)
 While (SQLCODE = 0) 
{
 for i=1:1:$LENGTH($P(colourList,","))
 {
 set fvalue=$P(colourList,",",i) 
write "the first"_fvalue,i, 
} 
}

the query returns colours but its just a string no delimiter eg;

green red blue

I have tried with

&sql(SELECT LIST(colour) INTO :colourList FROM favouritecolours)  

but still same results .

I am new to Intersystems Cache, so please bear with me. We are using HealthShare 2013.1. 

I have a routine to compare databases from separate instances where I want to ignore values that begin with %sqlcq. I thought this would be easy with pattern matching operator '?' but it is proving difficult and it seems to be because of the percent character. 

For example:

set x = "%sqlcq.something.value.foo"

#;does not evaluate as true. 
if x?1P1"sqlcq" {write "valid"}

set y="sqlcq.something.value.bar"

if y?1"sqlcq".E {write "valid"}
valid
if x?1"sqlcq".

Our development server is set up to automatically keep the .INT code of compiled classes and routines, but the live servers are set to not keep the .INT code.

I know how to set the system to keep this code ($SYSTEM.OBJ.SetQualifiers() ?)  but what are the ramifications of keeping this code on the live servers?  Is it just a space issue?  I always thought it was to keep the code more private.

Method1(){

Set OID1=##class(Table).%OpenId(100)

// do Kill OID

}

&SQL(Update Table Set  Column=88)

Method2(){

Set OID2=##class(Table).%OpenId(100)

// Or do %Reload()

Set OID.Column=99

Do OID.%Save()

}

// Column 1 still holds value as 1

For getting the updated value I should do Kill OID in Method1

Documentation here lists the kinds of members a class definition may contain. In summary:

• Parameters
• Methods
• Properties
• Class queries
• XData blocks
• Projections
• (and some that are relevant only for persistent classes):
  • Storage definitions
  • Indices
  • Foreign keys
  • SQL triggers

Later in the same document, a section headed "Class Member Names" contains this warning:

So I'm interested to hear how other DC members handle this.

1. Do you comply (or at least attempt to comply) with this?
2. If so, do you use any tools or naming conventions to assist you?

I am trying to write an application that will take some information on the database make a call to the Google API distance matrix and get the information to use with rest of the application without using the ensemble part of the development is this possible and how can I do my communication with the  API from a cache class thanks in  advance

I need to create a standards document for new developers who are coming to Cache from other backgrounds.

Does anyone have an in-house document they could share with me?

Regards

Mike
