2. Sometimes you WANT and NEED to do the full scan. And my topic was about these cases. In some programming languages, we even can find reserve words for such, e.g. for each.
And again your comment is interesting and helpful and deserves another topic too.
Thanks, Ed! Two remarks:
1. You mention iteration over resultset and introduce an example of iteration over array of columns cortege or record.
2. My question is not about getting values from arrays like list, locals, ppg, globals but what is better to use when you have a case of full scan over the array that in some cases lists are handier vs locals etc.
Though the question of what array is better when you need to get values for keys is interesting too, maybe it's another good topic for discussion. Answering your statement here I agree for LB the choice for value by position if it's not a very large (huge) array, where the global is the only answer.
@David Loveluck, thanks for sharing!
Do you want also to submit the code to Github and Open Exchange?
I was looking at @David Underhill's code for Metrics project and decided that for one level global traversing his code style is the most readable:
s database="" for {
s database=$o(databases(database))
q:database=""
...
}
And in general:
s iter="" for {
s iter=$o(^array(iter)) q:iter=""
// do something
}
So, use for instead of while for global traversing and this is readable and you never miss the next set is in while example.
Cool. And what is better with while $listnext from the performance point of view - local variable or refer to a parameter every time?
Thank you, @Eduard Lebedyuk and @Alexander Koblov! I agree, $lb variant is much better here.
Very rich library and awesome package structure and ObjectScript styling. Perfect work, thank you Richard!
Hi Ed!
Does RestForms leverage %JSON.Adapter functionality to expose classes data to REST via JSON?
Mine is faster ;)

Hi Vivek!
If you want to check for all the required fields instead of checking it on %Save, you better scan the class before %Save on the properties with required flag and check whether you have the value for it.
IMHO, this is the only way to show all the required fields at once.
And!
It worth to mention, that credit in development goes to:
Thank you very much, guys! I hope the list of contributors will be much longer soon!
1 - Is there any plans to automatize the
module.xmlgeneration by using something like a Wizard?
Submit an issue? More over, craft a module which supports that! And PR - it's a Community Package manager.
3 - Is it possible to run pre/post-install scripts as well? Kind of what installer classes do.
I think, this already in place. @Dmitry Maslennikov who contributed a lot will comment.
4 - Is also possible to use the
module.xmlto provide a contextual root?
We maybe can use the code! Thanks! @Dmitry Maslennikov ?
Hi Vandrei!
Als check the video on how to start coding InterSystems Object Script with GitHub and VSCode on IRIS Community Edition. Takes 5 min.
Thanks, Udo!
Another version of KYC - Know Your Community )
Julian, you are welcome!
There is a lot of other good stuff on InterSystems Open Exchange made by this community developers.
Thanks @Julian Matthews !
Also just to add - this situation could be reproduced in a real-world too: this is a Web Terminal made by @Nikita Savchenko , which is quite installable into any IRIS, Caché, Ensemble, etc.
Hi Dmitry!
So the new release on VSCode on Open Exchange.
It says - there is a debugger now.
How to introduce a breakpoint?
Great! Happy to hear that
Hi Salma!
isc dev is a community project. So you either can submit an issue or/and contribute the desired functionality by yourself and PR it to the repo.
Perfect!
So, what is the setting of this parameter to export classes into:
/src/cls
folder?
Sorry Vivek. My code provides you the Id of objExternalUser you save (possible create) above. It's 1).
It's not the latest inserted record. I thought you need:
I need RowId of inserted record.
Out of curiosity: why do you need the latest record?
Hi Vivek!
Instead of &sql ...
you can do:
write objExternalUser.%Id()I agree. I don't know the reasons which caused to limit the MAXLEN to 50 characters...
It steals months (if not more) of developers time to find out what was the bug and why this doesn't work because of MAXLEN=50;
And no "side effects"? )
As I see in your code you already do some "error handling". So you can continue:
Change your code
Do objExternalUser.%Save()to the following:
set stat=objExternalUser.%Save()
if $$$ISERR(stat) {
#; error handling
d $System.OBJ.DisplayError(stat)
}
HTH.
Out of curiosity - you have empty Try-Catch block. Why don't use it?
you could embrace your code into the following:
$$$TOE(objExternalUser.%Save())And catch your error with status in catch then.
Hi @Vivek Nayak!
Always check the status of %Save - it could result in an error. And I think this what was happened in your case.
90% of my "it doesn't save" with %Save caused by MAXLEN of %String property. %String property goes with MAXLEN=50 by default and it's often not enough. Check you have a such ;)
Thanks, @Herman Slagman!
If you want to share this and other items on DC-Innovations issues? Would be great.
Dear @retolik frolki !
If you ask your question on the Spanish Community you have more chances to get an answer.
