Actually, the case is very practical.

We need to know, which of the tags in DC relate to InterSystems Products and Services.

Every post on DC has a Tags field, which is a comma delimited string,  consists of  any of 150+ tags.

We need to form a Big Tag field, which is filtered Tags field with only the following values:  Caché, Ensemble, HealthShare, Intersystems IRIS, DeepSee, iKnow, Atelier, Online Learning, Documentation, WRC.

E.g. this particular post has Tags: Beginner, Caché

Big Tags will be: Caché

My variant is the following. General function of extracting subtag from tagsring which contains certain tags (intag):

ClassMethod SubTag(intag, tag, dlm As %String) As %String

{



for i=1:1:$L(intag,dlm) set intag($p(intag,dlm,i))=""

for i=1:1:$L(tag,dlm) {

set t=$p(tag,dlm,i)

if $D(intag(t)) set subtag($Seq(subtag))=t

}


while $d(subtag($Seq(l))) {

set $p(subtag,dlm,l) = subtag(l)

}

return $G(subtag)

}

And the calling function:

ClassMethod BigTag(tag As %String) As %String

{

set intag="Caché,Ensemble,HealthShare,Intersystems IRIS,DeepSee,iKnow,Atelier,Online Learning,Documentation,WRC"

return ..SubTag(intag,tag,",")

}

Usage:

USER>w ##class(Utils.Strings).BigTag("Beginner,Caché,Ensemble")
Caché,Ensemble
USER>w ##class(Utils.Strings).BigTag("Beginner,Caché")
Caché
USER>

Sorry, Alexey )

They are clickable for real but on the leaderboard pages. Here is the ObjectScript leaderboard, which you can join if you register on Advent of code site with email - and you'll have normal "white" name, and "green clickable one", if you join via Github or any other applicable for Advent site OpenID provider.

E.g. see the overall "world-wide" leaderboard which is available without authentication.

Hi, Alexey! Greens are clickable )

Here is the final Leaderboard for the contest is:

1st place - @Fabian.Haupt

2nd place -@Bert.Sarens

3rd place - @Dmitry Maslennikov

Congrats to winners and to all the participants!

We'll provide all the prises shortly and would appreciate if you share your repos (a lot of participants already did).

It would be great to know how people solve the same tasks with ObjectScript independently. Thanks in advance!

Thanks Sean, very interesting! Looking forward to see your Python-to-ObjectScript transcompiler.

Interesting thoughts, thank you, Fab!

@Bert.Sarens, @Timothy Leavitt, @Dmitry Maslennikov, @Michael Breen,@Sean Connelly, @ivo Ver Eecke and others - and what are your top places by days?

And your comments about ObjectScript and how could we perform better e.g. next year are very welcome too!

Cool battle! Congrats, to all participants and @Fabian.Haupt as a winner!

@Bert.Sarens, @Fabian.Haupt - you have more than 1,000 points both in ObjectScript leaderboard: why don't you listed on a general leaderboard?

Hi David! Thanks for reporting this. Our support team will contact you via GM direct messaging.

Hurry up to get your $100 from December Caché and IRIS campaign from Gartner and InterSystems! ;) Only 12 days left!

The recipe is the following: 

1. You are our current customer of Caché or/and InterSystems IRIS.

2. Make the review using this link.

3. Get your $25 for Caché or InterSystems IRIS review ($50 for both).

4. Save the screenshots of reviews and submit it in Global Masters - get another $25 for every Caché and InterSystems IRIS from Global Masters.

5. Merry Christmas and have a great new year 2019!

Hi Rob! 

Thanks for the update!

Is it only for Caché or is QEWD-up is suitable for InterSystems IRIS as well?

Also, why don't you publish QEWD on Open Exchange?

Hi Gevorg!

Is this fair for InterSystems IRIS as well? 

This is the current leaderboard:

Though leaders are high, the nature of the contest lets anyone who'll join the game today to win the contest!

So, join and win with InterSystems ObjectScript )

Hi Ramya!

Also see the discussion and this video - I show how to create namespace and database in terminal.

I decided to participate too!

Here is my repo.

And here is a short "Coding talks" Video on how to code Advent of Code and use Github and VSCode.

Hi Bert!

I think you are right twice. First, no one can stop cheating in the world and the second no one can win this contest with cheating. And of course no one can stop copy-n-paste in coding :) On the other hand, there is a chance to know something new even with copy-pasting.

As a community manager, I would love to see more open repositories with ObjectScript and I like what we had last year - the open discussion of Advent of Code problems solved with ObjectScript. Thanks for sharing your repo! 

Speaking about the prize it's clear that it can be interesting only to people who develop with InterSystems Data Platforms and I believe this is the key motivation to win.  

As we see it now the competition is active and healthy, we don't plan to change any rules but encourage the fair play.

Available on Open Exchange! So fast!

Jean, could it be ported for InterSystems IRIS too?

If you are interested in GraphQL maybe you want to check an implementation for InterSystems IRIS. And two articles about it - first, second.

Hi Marco!

It supports GraphQL as far as I know. Pinging @Rob Tweed.

Cool staff, Jean!

Do you want to publish it on Open Exchange?

Yet another great example of a repo for Advent of Code in ObjectScript
