With what we've done the syntax ends up looking like:

Class DC.Demo.Hierarchy Extends %Persistent [ MemberSuper = AppS.Index.Methods ]
{

Property message As %String;

Property login As %String;

Property parentId As DC.Demo.Hierarchy [ SqlFieldName = parent_id ];

Index parentId On parentId [ Type = bitmap ];

ClassMethod RunDemo()
{
    Do ..%KillExtent()
    &sql(insert into DC_Demo.Hierarchy (message, login, parent_id)
        values ('Bacon ipsum dolor amet pork shoulder ribs', 'User 1', null))
    &sql(insert into DC_Demo.Hierarchy (message, login, parent_id)
        values ('BGouda croque monsieur emmental.', 'User 2', 1))
    &sql(insert into DC_Demo.Hierarchy (message, login, parent_id)
        values ('Manchego fromage frais airedale', 'User 3', 2))
        
    Do ##class(%SQL.Statement).%ExecDirect(,
        "select id, message, parent_id from DC_Demo.Hierarchy "_
        "where id %FIND DC_Demo.Hierarchy_parentIdFind(2,'all descendants')").%Display()
        
    Do ##class(%SQL.Statement).%ExecDirect(,
        "select id, message, parent_id from DC_Demo.Hierarchy "_
        "where id %FIND DC_Demo.Hierarchy_parentIdFind(3,'all related')").%Display()
}

}

Because there's a self-referencing property with a bitmap index, the hierarchy support is automatic via the MemberSuper class. Output is:

d ##class(DC.Demo.Hierarchy).RunDemo()
ID    message    parent_id
2    BGouda croque monsieur emmental.    1
3    Manchego fromage frais airedale    2

2 Rows(s) Affected

ID    message    parent_id
1    Bacon ipsum dolor amet pork shoulder ribs    
2    BGouda croque monsieur emmental.    1
3    Manchego fromage frais airedale    2

3 Rows(s) Affected

There's nothing built-in for this, but you can simulate it via custom class queries or %SQL.AbstractFind. I have an implementation of %SQL.AbstractFind/%Library.FunctionalIndex that does some things with hierarchies but falls short of the capabilities you linked in the Oracle doc. Specifically, it can find all ancestors/descendants/both (the whole tree) in a hierarchy efficiently, but it doesn't follow the same rules around ordering and won't let you do paths and such. (I'd want to clean it up a good deal before sharing, but that's probably worthwhile at some point.)

You can use as modern HTML and CSS as you want.

@Daniel Bertozzi , following up - I downloaded ImageMagick and the following works just fine for me (though I'm a little surprised at how slow it is):

Class DC.Demo.ImageMagick
{

ClassMethod Convert(inFile As %String = "C:\Temp\ImageMagick\inFile.jpg", outFile As %String = "C:\Temp\ImageMagick\outFile.jpg")
{
    Do $zf(-100,"","magick",inFile,"-resize","640x480",outFile)
}

}

I think the likely issue is that ImageMagick isn't on your PATH. You'll need to restart your instance for it to pick up PATH changes, so this might be the root cause if you just installed ImageMagick. Could also be interesting to run with the /SHELL flag and see if that works.

Hopefully this helps!

In communication outside of this thread, turns out the issue stemmed from a failed %Save() - something like:

Class DC.Demo.OREFOIDDemo Extends %Persistent
{

Property Foo As %String(VALUELIST = ",Bar");

ClassMethod RunDemo()
{
    Do ..%KillExtent()
    
    Set thingOne = ..%New()
    Set thingOne.Foo = "Bar"
    Do thingOne.%Save()
    Set thingOne.Foo = "Baz"
    Do thingOne.%Save()
    
    // Later, and elsewhere, because thingOne happens to be in memory,
    // it appears that the value "Baz" has been persisted:
    
    Set thingTwo = ..%OpenId(thingOne.%Id())
    
    Write !,"thingOne = ",thingOne
    Write !,"thingTwo = ",thingTwo
    Write !,"thingOne.Foo = ",thingOne.Foo
    Write !,"thingTwo.Foo = ",thingTwo.Foo
    
    Write !,"thingOne.FooGetStored(thingOne.%Id()) = ",thingOne.FooGetStored(thingOne.%Id())
    
    Do thingTwo.%Reload()
    Write !,"After thingTwo.%Reload(), thingOne.Foo = ",thingOne.Foo
    Write !,"After thingTwo.%Reload(), thingTwo.Foo = ",thingOne.Foo
}

}

Which produces output:

Do ##class(DC.Demo.OREFOIDDemo).RunDemo()
thingOne = 15@DC.Demo.OREFOIDDemo
thingTwo = 15@DC.Demo.OREFOIDDemo
thingOne.Foo = Baz
thingTwo.Foo = Baz
thingOne.FooGetStored(thingOne.%Id()) = Bar
After thingTwo.%Reload(), thingOne.Foo = Bar
After thingTwo.%Reload(), thingTwo.Foo = Bar

Poking around a bit, here's the best explanation I could find for how to implement such behavior: https://stackoverflow.com/a/7317311/2323797

Given that SQLCODE is 100 (in other comment thread), might you have an index on %ConfigName that has not been built?

What do you see from the following queries?

select * from X_X.X where %ConfigName IN ('X_X_X','Y_Y_Y')

select * from %IGNOREINDEX * X_X.X where %ConfigName IN ('X_X_X','Y_Y_Y')

Also, is X_X.X the table corresponding to the class where the property is defined?

Short answer: yes, ZPM can manage whatever you want other than ObjectScript, it just takes a little extra work.

Longer answer:

This "extra work" involves writing a class that extends %ZPM.PackageManager.Developer.Processor.Abstract and overrides OnBeforePhase or OnAfterPhase, then implementing whatever behavior you want. You can see a bunch of classes in the %ZPM.PackageManager.Developer.Processor package that do this.

I'd imagine being able to put something in the Resources element of module.xml like:

<Resource Name="/external-dependencies/some-package" ProcessorClass="MyPackage.AptGetInstall" />

Where MyPackage.AptGetInstall overrides OnAfterPhase and for the "Activate" phase runs apt-get install <name of resource following "/external-dependencies/"

The catch:

If you want to support all operating systems, think about what the Windows equivalent would be and/or add defensive coding to avoid trying to run the command on Windows.

Here's how I'd typically do something like that, going back to my example from one of your earlier questions and expanding a bit. The persistent class as a new %Boolean property named "Toggleable" (not a magical name - you can call it whatever you like), and the tablePane has <column> elements added. The query supplying data for the table has the ID and Toggleable columns added as well. The "Toggleable" column has OnDrawCell defined to provide custom HTML for the cells in the table; this references an ObjectScript method (which doesn't need to be, and in fact shouldn't be, a ZenMethod). That ObjectScript method renders HTML which calls a ZenMethod to actually do the update, using query results from the %query variable (which is a special thing that's available for use in OnDrawCell). No table refresh is needed, but if you refresh the page you'll see that the checkbox values have indeed been persisted.

Here's the Zen XData change:

<tablePane id="myTable" OnCreateResultSet="CreateResultSet" valueColumn="ID">
<parameter value="" />
<parameter value="" />
<parameter value="" />
<column colName="ID" hidden="true" />
<column colName="Name" />
<column colName="SomeDate" />
<column colName="Toggleable" OnDrawCell="DrawToggleCell" />
</tablePane>

And corresponding ObjectScript methods:

/// Note: this doesn't need to be a ZenMethod.
ClassMethod DrawToggleCell(pTable As %ZEN.Component.tablePane, pColName As %String, pSeed As %String) As %Status
{
    &html<<input type="checkbox" #($Case(%query("Toggleable"),1:"checked",:""))# onchange="zenPage.Toggle(#(..QuoteJS(%query("ID")))#,this.checked)" />>
    Quit $$$OK
}

ClassMethod Toggle(pID As %String, pValue As %Boolean) [ ZenMethod ]
{
    Set obj = ##class(DC.Demo.SampleData).%OpenId(pID,,.sc)
    $$$ThrowOnError(sc)
    Set obj.Toggleable = pValue
    $$$ThrowOnError(obj.%Save())
}

Here's the full sample:

Class DC.Demo.SampleData Extends (%Persistent, %Populate)
{

Property Name As %String;

Property SomeDate As %Date;

Property Toggleable As %Boolean;

}

Class DC.Demo.ZenPage Extends %ZEN.Component.page
