Using Gravatar, It is a good idea.

But, I think there is a some problem with it. Most of accounts here uses corporate e-mails, but in any other places we are using our private e-mail, I do so. And I hava gravatar for years, and it uses only my private addresses, and sure most of people here too.

Unfortunately, no one file can be downloaded, with 404 error

In Amazon for example as I know, you may use private network with machines without any public IPs, only private static or dynamic address by your own dhcp setver. And in this case I don't see any troubles in using Mirrors in cloud. I think any others cloud prividers have such possibilites. 

In our company, all developers usess their own installation of Ensemble. We develop web-application, and most of our changes we do on server-side code, and support only one version of Caché. In a team with more then one developer, but on one server much easier to disturb to others developers on this server.  And with a web-based application, you also need to change some static files, such as  JS or CSS, so in this case you can't split changes from different developers if you use any source control system. On his own server developer have a full control on development environment. 

Only in cases, where server uses only to store some data or with so small changes of server's code, and client works via network, possible to work on single server for all developers.

Since Atelier now has a client side folder, for edited files, you can't just edit server's files.
You should copy such classes or routines to the project before, by menu Copy to project. In dialog you should choose already existed project, and after Finish button, that files will be available for edit.

If you think, that really need some new language in Caché. You can add with some limitiations, if Studio already can highlight that language. Now you can do it only in Studio, Atelier does not support it. I've already wrote a short post about something like you want. And about javascript-like language which can be executed on server side, because compiles into COS, yet in russian, and it will be transleted in english some time later. In that my article, I used as an example code

// hello
console.log('Hello World!');

var name='';
read('What is your name? ', name);
println('Hello ' + name + '!');

which compiles to

    Write "Hello World!",!
    new name
    set name = ""
    read "What is your name? ", name,!
    Write "Hello "_ name _"!",!

Thanks a lot

You may call RunTest with /noload parameter, but you still have to set a valid directory  as a value in ^UnitTestRoot

Set ^UnitTestRoot = "C:\UnitTests"
Do ##class(%UnitTest.Manager).RunTest("mytests:MyPackage.Tests", "/noload/nodelete")

Or so, here you can specify: suit, class and method if you want

Do ##class(%UnitTest.Manager).DebugRunTestCase("mytests","MyPackage.Tests","","")

This call does not load any classes from any directories nor does it delete any classes from Caché. And executes the tests contained in MyPackage.Tests. The optional third argument is for specifying an individual test method within the test class to execute.

Yes, it is possible, but you should be ready to change it after all updates of Caché

Read about it in documentation  - Localizations

In first you should export current localization 

DO ##class(%Library.MessageDictionary).ExportDomainList("messages_sqlcode_en.xml","%SqlCode","en")

here %SqlCode, it as a domain for Sql Codes. And any language which you want to change.

then you can change any text in this xml, and should keep all off tags with their Id attribute, if you delete some tag, you will loose their localization. And then you can import your new localization. As it system localization, you have to allow writing to CACHELIB database.

do ##class(%MessageDictionary).Import("messages_sqlcode_new_en.xml")

You have to remember that it is a system localization, and InterSystems can change it, add or remove anything here, and in every new version, you should follow theri changes.

Or much simple way, it just set new value directly to  the global.

USER>set ^%qCacheMsg("%SqlCode","en","SqlCode139") = "TEST Concurrency failure on update: row versions not the same"
 
USER>Write $SYSTEM.SQL.SQLCODE(-139)
TEST Concurrency failure on update: row versions not the same

There are some ways to concat values in a cloumn in Caché: CONCAT and STRING.

CONCAT concatenates two strings to return a concatenated string. You can perform exactly the same operation using the concatenate operator (||).

STRING converts one or more strings to the STRING format, and then concatenates these strings into a single string. No case transformation is performed.

Thanks, and what about spoiler blocks ?

I just have found that $system.OBJ.Load() supports loading in an UDL format. And found $system.OBJ.ExportUDL() which can export classes and routines in UDL format. So, it means that we can easily organize work in Studio and in Atelier at the same time. What we should, it is to export all files in Studio hook at the same manner as it doing Atelier.

With this new possiblility, will be much easier to migrate from Studio to Atelier.
Thanks.

Well, we got very exciting feature.
But how about some more methods for arrays, such as:  $unshift, $pop, $shift, $concat, $join, $slice ?
It would be very helpful.

And as we have $listbuilds in Caché, I want to easily convert it to json array like below
set array = ([]).$from($lb(1,2,3))

do array.$toJSON()

[1, 2, 3]
 

As you may already know, tables in Caché is a classes. And Class defintion stores in %Dictionary Package.

SELECT * FROM %Dictionary.PropertyDefinition where parent='Sample.Person'

Ok then, how to manage to get it worked with REST in Caché. For example. My application uses REST dispatch class for csp application. This class returns static files from disk in development, or from XData in production. And then I need to use WebSocket as well, but all requests catch by REST class. And in REST route map, i want to have path '/websocket', and send it to my WebSocket class.
