Hello,

I wonder if there is any way caché studio organize the source code automatically, similar to what the netbeans does.

Weblink availability long-term.

Hi,

I sometimes get asked if Weblink will still be available (as a downloadable ad-on these days) for some versions to come.

I realize that this is old technology now, and that there are better and faster ways to do the same things today.

Thanks

%Library.GlobalCharacterStream deprecated

On the class reference %Library.GlobalCharacterStream is marked as deprecated in favor of %Stream.GlobalCharacter.

How I can migrate the data from class properties defined as %Library.GlobalCharacterStream to the new one %Stream.GlobalCharacter?

Does the %Stream.GlobalCharacter have the same SQL support from %Library.GlobalCharacterStream?

Thanks.

Bootstrap's $navbar

Hi, The ZEN Mojo Widget reference at ../csp/sys/%ZEN.Mojo.WidgetReference.bootstrap33xHomepage.cls is a great reference for viewing the different components available with each helper plugin - and it also supplies snippets of JSON code to use in your layout definitions.

I'm having problems with the Bootstrap $navbar component however. This is layout definition, with a navbar and button contained within the bar.:

Modifying REST.DocServer to use new %Object instead of %ZEN.proxyObject

I was trying to modify the REST.DocServer sample in the SAMPLE namespaces to use the new %Object and %Array system objects (Ensemble 2016.2 build 636) with the following changes:

/// This method returns a list of namespaces for this server

ClassMethod GetNamespaces() As %Status

{

#dim tSC As %Status = $$$OK

#dim tList,tNS,tFilteredList,tValue As %String

#; Get the list of namespaces

Do List^%SYS.NAMESPACE(.tList)

Set tNS="" For {

Set tNS=$Order(tList(tNS),1,tValue) If tNS="" Quit

Syntax for calling label when using extended routine reference

I get NOROUTINE when I try to call a label in a routine in another namespace:

d someLabel^|”OTHERNAMESPACE”|someRoutine(inputVar,.resultByReference)

Two questions:

1. What is wrong with my syntax for calling a label in the other routine, versus just the root of the .int/mac?

2. Can I pass a parameter by reference when using extended routine reference?

Is there a way to run unit tests in a given project which _does not_ require that test classes be exported first?

Hello,

It is time for me to eat my own dog's food and start implementing unit test running with coverage :) I will be inundating IRC with questions at this point, but I have a more general question first.

In this tutorial, it is supposed that your unit tests are exported as XML first... But that's not very practical. Is there a way, instead, to run all tests from a given project without having this export?

My first thought on how to do this would be to:

What is the best practice when the intent is to make a package available to all namespaces?

Hello,

Still related to the unit test with coverage support project, one goal is to make that package available to everyone.

One possible way I already know of is that all fully qualified class names (ie, the package + the class name) start with %, which mean that on installation all classes will end up in the %SYS namespace, but this requires that the install be done as a user with the necessary privileges to write to %SYS.

How to determine SQL access available?

I have two servers in our TEST environment. One with HSBUS and one with HSREGISTRY. Let's call them "HSBUS01" and "HSDB01" respectively.

Now, I can access HSBUS with my SQL client by using the JDBC driver pointed to hsbus01.full.name.com and port 1972 and specifying a namespace of "HSBUS". I am, however, unable to access the HSREGISTRY instance via SQL with a similar combination of information.

Reducing select fields hurts query performance

We have a query that looks something like:

select a, b, c, d, e, f

from tbla inner join tblb on tbla.....

This query runs in the expected 200-400 ms range.

If we run the same query but reduce the select to just:

select a

from tbla inner join tblb on tbla.....

then the query runs for 30 minutes or more.

The rest of the query is identical. Is there a logical explanation for how this can happen?

Thanks.

Pull out characters from the middle of a text string using SQL

I have to disect thousands upon thousands of strings like this:

96842-2-AEV.00001-63561-001958-100728760I-42

I've been able to pull out the first, second and final segments as separated by hyphens, but now I have a predicament where I need to use the second segment, the 2 shown in the example above, in a join to another table. Problem is Cache apparently doesn't like doing that. Just the same, I have to find a way.

Here's the code I'm using to pull that segment out into as separate field in the query results:

iFind index missing data

I've been using iFind indices in one of my applications but this morning discovered that the index is missing data. I confirmed the issue also exists in our test environment and rebuilt the indices there. That seems to have fixed the immediate problem. However I'd like to understand how this came about to avoid it happening in the future.

Has anyone encountered this before and know the cause?

I followed the Documentation instructions to install Caché on my Linux box and it seems to be running fine except when I try to modify the configuration. I keep getting errors that a previous cache.cpf file (e.g., cache.cpf_8503) cannot be opened. Is my Linux "user who owns instance" account deficient in Linux permissions?

Is there a table somewhere of deprecated classes/added keywords/etc and _when_ these changes took place?

Hello,

For CachéQuality I'd love to be able to create issues when the programmer uses classes which are deprecated for this or that version of Caché... But short of reading all the changelogs of all versions, I can't really tell when a command appeared (for instance RETURN; I know now that it appeared in 2014.x, but it took me some time to realize that), or when a (set of) class(es) became deprecated (for instance %GlobalCharacterStream to be replaced with %Stream.GlobalCharacter -- I don't even know since which version this is true :/).
