Hi Emmanuel,

This particular extension is for Visual Studio Code only, at the moment. Different IDEs I hope will come in the future. And possible for Visual Studio as well.

VSCode supports Cyrillic, so, don't see any possible issues with Hebrew.

Visual Studio Code and Visual Studio are two completely different projects. There is only one thing between them, both developed by Microsoft. Don't be confused by similar names. 

So, you should not be worried to use VSCode and Visual Studio on the same machine side by side.

Possible reasons

  • Another recommendation is to separate code and data. So, I need at least two databases, code which is always in a container, and data mounted outside.
  • Just to be consistent, some project, and namespace with the same name as the project. With only own configuration. Without anything predefined. In most cases, namespace and any related configuration, supposed to be configured for the particular project. And keeping USER as is and do not touch except for some temporary staff, like import Installer manifest and setup it.
  • One of the reasons for USER still exists, that it is kind of entrypoint, and keep it as is, will keep from anything unexpected.

Just my thoughts

Any IRIS edition includes formerly known as Ensemble feature, which is now is Interoperability (and one of the letters in IRIS).

You may get this error if you work in the namespace where Ensemble was activated. By default for USER was not activated.

When you create a new namespace Ensemble checkbox checked by default and, but you can uncheck it.

to enable namespace manually, do this command

do ##class(%EnsembleMgr).EnableNamespace("YOUR-NAMESPACE")

$listvalid

%SYS>w $listvalid($lb("test"))
1
%SYS>w $listvalid("test")     
0
%SYS>w $listvalid("")    
1

$listbuild is not an object, so, it's not a check as an instance of, it is only possible that variable is valid as $listbuild

$listbuild as just a string with a special format, so, that's why this will also return true

%SYS>w $listvalid($char(1))   
1
%SYS>write $lb()=$c(1)
1

because

%SYS>zzdump $lb()  

0000: 01                                                      .

So, to get own docker-running Cache, is quite easy.

You just need docker desktop installed on your mac. Then when it installed, and running. You'll be able to run it from the terminal by command.

docker run -d --name cache \
  -p 1973:1972 \
  -p 57773:57772 \
  -v $HOME/cache.key:/usr/cachesys/mgr/cache.key \
  daimor/intersystems-cache:2018.1

It supposed that you have valid cache.key in your home directory. And that your ports 1973 and 57773 is free to use. If you would like to change the port just change 1973 and 57773 with any you'd like to use.

This command will download the image (daimor/intersystems-cache:2018.1) from the public repository, and run it in the background.

You can control the running container by commands, wherein all subsequent commands cache is the name of the container from the docker run command.

To see cconsole.log of the container.

docker logs cache

To look at the status of the container

docker ps cache

Stop running container

docker stop cache

This is just an empty instance, to look at how it works. In the real case scenario, some more work should be done.

Docker images for Cache or for Ensemble are provided by me, and it is available for different versions.

Nowadays is best to migrate to IRIS, and use official images provided by InterSystems itself.

And the next step for you would be to use an editor that can be run on macOS, instead of Studio which working only on Windows.  

And you can use VSCode editor with an extension VSCode-ObjectScript, developed by me. 

I would recommend reading here articles tagged by Docker. There much more information about how to best use it. 

As well as about using VSCode.

You can contact me directly, if you need any help with establishing development process, with such modern tools as Docker and VSCode. or migrating to IRIS.
