This is beautiful! I like $tr!

But wrong )

 E.g. it would not work for this example:

oiii ioii iioi iiio 

it's not valid, but for your example would be valid.

I wonder, guys, how did you solve that the word is Anagram in Day4:

A valid passphrase must contain no two words that are anagrams of each other - that is, a passphrase is invalid if any word's letters can be rearranged to form any other word in the passphrase.

For example:

  • abcde fghij is a valid passphrase.
  • abcde xyz ecdab is not valid - the letters from the third word can be rearranged to form the first word.
  • a ab abc abd abf abj is a valid passphrase, because all letters need to be used when forming another word.
  • iiii oiii ooii oooi oooo is valid.
  • oiii ioii iioi iiio is not valid - any of these words can be rearranged to form any other word.

 

My solution is:

ClassMethod IsAnagram(word,test) as %Boolean {

if $L(word)'=$L(test) return 0

f i=1:1:$L(test) if $seq(test($E(test,i))),$seq(word($E(word,i)))

set a=$O(word(""))

while a'="" {

if word(a)'=$g(test(a)) return 0

set a=$O(word(a))

}

return 1

}

The full solution is here.

Thanks for the answers!

The combined answer is - build it again if you don't care about the time during deployment.

For Caché persistent classes I like this snippet from [@Kyle Baxter] which rebuilds all persistent classes' indexes in a Namespace:

s sql="select Name from %Dictionary.CompiledClass where system=0 and NOT(Name %Startswith '%') AND SUPER [ 'Persistent'"

s rs=##class(%SQL.Statement).%ExecDirect(,sql)

while rs.%Next() { s sc= $classmethod(rs.%GetData(1),"%BuildIndices") w "Built "_rs.%GetData(1)_" with return code = "_sc,! }

This is similar documentation for mapping Routines.

And one note: if you map routines, put the routine name without extension.

E.g. if you want to map MyMacro.inc from USER to %ALL run the following in %SYS namespace:

%SYS>s props("Database")="USER",sc=##Class(Config.MapRoutines).Create("%ALL","MyMacro",.props)

Nevermind, everything works fine!

Just to be clear: your line of code shows how to create the mapping of PackageA in Database SAMPLES to Namespace USER.

Thanks, Dmitry!

Though the parameter for a 'namespace-to-map' with a name "Database" looks weird.

Interesting about MANAGEDEXTENT. 

I'm curious, what are the typical use cases, when MANAGEDEXTENT can be helpful?

Evgeny Shvarov · Nov 27, 2017 go to post

Interesting. Never knew about MANAGEDEXTENT parameter, mentioned by @Robert.Cemper. And yes, backup your globals.

But in your case, @Nikita Savchenko, I would go with the following. Consider you have class A and rename it to class B.

1 - is yours.

1a. When duplicating be SURE, that you take class storage definition from A, not generate it because of compile. Change places with global A  to global B in storage definition and compile class B.

It's MANDATORY to take class A storage def to B class definition and compile after that and not use generated storage definition in class B.

2. Merge data globals from class A to class B. E.g.

USER> m ^BD=^AD

3-4 - yours.

5. Load new scripts and make global merges and test.

6. Is yours.

Thanks, John, Jeff. It's a bug. We have this behaviour but only for Groups. But it seems it works for Tags as well.

Hi, Mike! Will do, but have you tried with WRC via this entrance?

Click on it and you'll be redirected to InterSystems Login

Thanks, Konstantin!

And here is the link to the demo.

Do you want to add an option to share the search? E.g. introduce some share results button in UI which would provide an URL with added search option in URL? It would be very handy if you want to share search results with a colleague.

Thanks, Sergey!

Google it and you'll get thousands. It's a really number of it. I'm using LICEcap.

Thanks, Danny!

Actually, I raised already similar discussion but I still prefer object callbacks because of better code readability.

BTW, if I have both unified Trigger and OnBeforSave callback would they fire both?

And why don't we have unified ObjectScript callbacks?

Hi, Kevin!

I can advise trying Caché Class Explorer which exposes packages, classes, methods with code and interactively points to classes documentation on a given server and can be used to solve your task in my opinion.

Pinging @Nikita Savchenko to provide more information.
