From "Oops" to "Aha!" - Avoiding Beginner Mistakes in ObjectScript

#Globals #Languages #ObjectScript #Caché #Ensemble #Global Masters #HealthShare #InterSystems IRIS #InterSystems IRIS for Health #Other

Starting out with ObjectScript, it is really exciting, but it can also feel a little unusual if you're used to other languages. Many beginners trip over the same hurdles, so here are a few "gotchas" you'll want to watch out for. (Also few friendly tips to avoid them)

NAMING THINGS RANDOMLY

We have all been guilty of naming something Test1 or MyClass just to move on quickly. But once your project grows, these names become a nightmare. 

➡ Pick clear, consistent names from the start. Think of it as leaving breadcrumbs for your future self and your teammates.

MIXING UP GLOBALS AND VARIABLES

Globals (^GlobalName) can be confusing at first. They're not just normal variables. They live in the database and stick around even after your code stops running.

➡ Use them only when you really need persistent data. For anything else, stick with local variable. (This also saves storage.)

FORGETTING TRANSACTIONS

Imagine updating a patient record, and your session crashes halfway. Without a transaction, you are left with half-baked data.

➡ Wrap up important updates in TSTART/TCOMMIT. It is like hitting "save" and "undo" at the same time.

BUILDING SQL IN STRINGS

It is tempting to just throw SQL into strings and execute it. But that quickly gets messy and hard to debug.

➡ Use embedded SQL. It's cleaner, safer and easier to maintain.

EXAMPLE:

❌ Building SQL in Strings

Set id=123
Set sql="SELECT Name, Age FROM Patient WHERE ID="_id
Set rs=##class(%SQL.Statement).%ExecDirect(,sql)

✅ Using Embedded SQL

&SQL(SELECT Name, Age INTO :name, :age FROM Patient WHERE ID=:id)
Write name_" "_age,!

SKIPPING ERROR HANDLING

Nobody likes seeing their app crash with a cryptic message. That usually happens when error handling is ignored.

➡Wrap risky operations in TRY/CATCH and give yourself meaningful error messages.

IGNORING BETTER TOOLS

Yes, the terminal works. But if you only code there, you are missing out.

➡ Use VS Code with the ObjectScript extension. Debugging, autocomplete, and syntax highlighting make life so much easier.

REINVENTING THE WHEEL

New developers often try writing their own logging or JSON handling utilities, not realizing ObjectScript already has built-in solutions.

➡ Explore%Library and dynamic objects before rolling your own.

WRITING "MYSTERY CODE"

We have all thought "I'll remember this later."

⚠️SPOILER: YOU WON'T! 

➡ Add short, clear comments. Even a single line explaining why you did something goes a loooong way.

 

FINAL THOUGHTS : )

Learning Objectscript is like learning any other new language. It takes a little patience, and you will make mistakes along the way. The key is to recognize these common traps early and build good habits from the start. That way, instead of fighting the language, you will actually enjoy what it can do. :)

ExportUDL adds extra line at the end of class

#Git #ObjectScript #VSCode #InterSystems IRIS

Hi,

so we introduced GIT in our workflow and we exported all files with $SYSTEM.OBJ.ExportUDL

Everything fine so far. But for some reason the export adds an extra line for classes (Routines are OK as far as I can see):

On Serverside it isn't there

 

The Problem is now that when we checkout a branch and a class changed we automatically compile it from the repository to a namespace that is made for the developer. E.g. DEV_001, DEV_002 and so on. 

Now when the class get's compiled the objectscript plugin replaces the local version with the version that the server compiled, so the last line get's removed. And now GIT says there is a change in the file:

Discarding the change in GIT  results in a new change in the file wich is detected by the plugin and starts a new compile. Again, the compile removes the last line. So we are in a loop. 

What are we doing wrong here? Can't be working as intended. 

 

Objectscript-Plugin Version 3.0.6

 

BR

Abu Dhabi City Tour Journeys Through History and Modern Life

#Terminal #Other

Abu Dhabi, the capital of the United Arab Emirates, offers travelers an exceptional blend of heritage, modern architecture, and cultural richness.
