New post

Hi, Community!

We are fixing groups, tags and message types for the several last year's postings.

So that's why you are getting "strange" notifications now with no any new comment.

As a result, you'll get better tagging and for the DC articles and questions.

Anyway, you can turn off the "OnUpdate" notifications as it is described here.

Hi!

Today DC supports the notifications for the posts' updates. It means if someone changes the post text, title, group or tag you can be notified about that.

But this notifications just inform that there were updates, but do not show what exactly was changed in the post.

So through this, you can get the notifications for the posts from previous years without any reason what's happened.

I would suggest to turn off this types of notifications until we'll implement the details in notifications, what exactly was changed in the post and why did you get it.

DeepSee cubes building troubleshooting

Hi!

Sometimes you see that call to DeepSee cube building method:

w ##class(%DeepSee.Utils).%BuildCube("CubeName")

does nothing.

Here are my 2 cents on possible reasons.

1. Run DeepSee Reset method in certain Namespace:

NAMESPACE> w ##class(%DeepSee.Utils).%Reset()

and try again.

2. Make sure, that all the indices in your base class for the cube are rebuilt, rebuild them and run it again:

Hi, Community!

You know, that when we build hierarchies in DeepSee dimension all the members of lower level should be the part of one member of the higher level.

If not you'll get some empty results in MDX queries with this hierarchy.

With Time dimensions the obvious valid hierarchy is Year->Month->Day, cause every Month consists of one Year and every day consists of one month.

Debug: using locks for breakpoints

Hi, Community!

Want to share with you one debugging approach from the Russian forum.

Suppose I want to debug the application and I want it to stop the execution on a particular line.

I add in code this line:

l +d,-d

When I want to start debugging in this line I block d in terminal

USER> l +d

And execute the app.

The app stops on this line and lets me connect to it with Studio debugger.

Hi!

I believe the simplest is (to work with csv delimited by ";"):


set file = ##class(%File).%New( "data.csv" )
    set sc = file.Open( "R" ) 
    if $$$ISERR(sc) quit    ; or do smth

    while 'file.AtEnd {
        set str=file.ReadLine() 
        for i=1:1:$length( str, ";" ) {
            set id=$piece( str, ";" ,i ) 
            write !, id  // or do smth
        }
    }
    do file.Close()

Possible options:

different variants of error handling with sc code.

Embrace while loop into try/catch block.

And what's yours?

Hi!

Want to share with you code snippet of try catch block I usually use in methods which should return %Status. 


{ 
 try {
  	$$$TOE(sc,StatusMethod())
 }
 catch e {
 	set sc=e.AsStatus()
 	do e.Log()
 }

Quit sc 
}

Here $$$TOE is a short form of $$$TROWONERROR macro.

Inside macro StatusMethod is any method you call which will return %Status value. This value will be placed into sc variable.
