You can use $System.OBJ.Export() for it.

For every project where I need it I have a project cheatsheet file, where I have:

s list="MyPackage*.INC,MyPackage*.CLS,Folder*.DFI"
D $System.OBJ.Export(list,"release"_$tr($zd($h,3),"-","")_".xml")

So when I need to export the whole project into importable xml file I call these two lines in terminal.

We can change the email in Global Masters to make it compatible with DC to let us count points in GM for your DC contributions. Would it work?

At least you can have the benefits of Caché Web terminal itself: 

Code completion (methods, classes, properties, etc), code highlighting, nice SQL shell, endless history, etc.

I think it would be a great thing. 

So in case you have open ssh port, you would be able to work in a handy, good looking, fool functional terminal with class code completion, code highlighting and SQL shell.

Definitely, makes sense to me.

Hi, Francisco!

I'm not sure we can modify the email.

But you can register as a new member with another email. Would it work for you?

Iterating over indexed value can be very helpful. 

We have IndexOpen and IndexExists autogenerated methods (article on autogenerated methods) for persistent classes. I'm using these very handy methods a lot.

It would be great if somebody introduce Next/Prev autogenerated methods too e.g. via some NavigationAdapter class to derive from.

HI, Mike!

You don't have to. DC Telegram Channel is introduced for those who loves Telegram  mobile app as a way to communicate.

It is yet another channel to deliver DC content which is already posted on DC or DC YouTube.

But, we plan to introduce DC bot which can be interesting and unique for DC Telegram Channel.

Thanks, Vitaly!

That looks exactly like what I want. I'll give it a try. Except with not very clear magic with SQLStorage. 

Is there any way to "generate" compatible storage? And why SQLStorage? Why not default CachéStorage, but copy-pasted from Class A?

VIews work for SQL access. I really need a kind of view, but for classes paradigm: so I could have access to Class B property P2 with Caché object access.

When I've seen "ORM javascript" in the feature list I remembered yet another very interesting approach which is in fact the result of Hachathon took place in  Moscow two years ago: CNDO (Caché Node Data Object), project made by [@Nikita Savchenko], Anton Gnibeda and [@Irene.Mikhaylova].

Thanks, Dan!

That definitely makes sense.

What I like about object callbacks is the code readability. Compare:

Method %OnBeforeSave(insert as %Boolean) As %Status [ Private, ServerOnly = 1 ]

{

if insert s ..CreationDate=$H

q $$$OK }

And 

Property CreationDate As %TimeStamp [ SqlComputeCode = { set {*}=$zdt($h,3) }, SqlComputed, SqlComputeOnChange = %%INSERT ];

What if I would need to refer to other properties in

{*)=expression()

Or the expression would be complex and if I want to debug it?

Is there a way to keep callbacks readability and have the callback methods  be fired for object and SQL access both?

Something like:

Property CreationDate As %TimeStamp [ SqlComputeCode = { set {*}=..%OnBeforeSave(1) }, SqlComputed, SqlComputeOnChange = %%INSERT ];

Thank you, Rubens, Fabian, Sean.

Agreed, that Initial expression is the best option here. And thanks for the explanations on the callbacks!

Thanks, Sean!

JSON-RPC library

Would be great to look into this if you want to expose it some day.

Hi, Vineeth!

See the sample of exporting and importing global to zip file on the fly from @Eduard Lebedyuk post:

set ^dbg=123
set s=##class(%Stream.FileBinaryGzip).%New()
do s.LinkToFile("1.xml")
do $System.OBJ.ExportToStream("dbg*.GBL", s)
do s.%Save()
kill
kill ^dbg
set s=##class(%Stream.FileBinaryGzip).%New()
do s.LinkToFile("1.xml")
do $System.OBJ.LoadStream(s)
write ^dbg
>123

Hope that helps.
