I think the debugging experience in VS Code is actually better than Studio since you can view the properties of OREF's in the variables view in VS Code but not Studio. You can have that developer file an issue report on GitHub, or contact the WRC if you have a support contract.

As for features in Studio but not VS Code, the biggest one is the Inspector. It is very unlikely that it will ever be implemented in VS Code. VS Code also does not support integration with the legacy Zen BPL and DTL editors. VS Code will support integration with the new Angular versions of those editors when they are implemented. VS Code also doesn't support syntax coloring for Cache Basic or MultiValue Basic, but you can still edit those files.

@Anna Golitsyna 
The big plus is that VS Code is in active development, while Studio hasn't seen enhancements in years and now is deprecated. Other than that, here are some benefits of VS Code:

• Supports Mac, Linux and Alpine Linux in addition to Windows.
• Much faster release cycles so you get new features and fixes faster.
• Always forward compatible without needing to install a new version.
• Much better intellisense support. (a large list of features can be found here)
• Modern UI with fully customizable themes.
• Can be connected to multiple server-namespaces in the same window.
• Debugging supports expanding OREF's to see their properties.

Just to clarify for everyone, Studio source control classes that import/export XML files will continue to work and be supported. There just won't be a menu option in VS Code to export files as XML.

@Larry Overkamp 
VS Code does not support exporting or importing source code as XML files. There are existing tools in the terminal and SMP for that. The server-side editing paradigm that John mentioned above is conceptually similar to Studio in that the files you edit are "virtual" and do not need to be exported to the file system to be edited. It supports viewing all files in a namespace like in Studio, and it also supports importing local .cls, .mac, .int and .inc files into that namespace.

Searching for text across those virtual files is supported and the UI is much better than Studio since you can click on the match and jump right to that location in the file. Enabling that feature requires some extra steps due to a VS Code core limitation, but this is something that we anticipate will be resolved in the future.

We have a documentation page that describes some useful features for migrating from Studio that you may find useful.

The server-side editing paradigm in VS Code is conceptually similar to Studio in that the files you edit are "virtual" and do not need to be exported to the file system. This mode supports Studio source control classes, so you can continue using them if you want. We have a documentation page that describes some useful features for migrating from Studio that describes where the Studio source control integration can be found in the VS Code UI.

The vscode-objectscript extension does provide New File commands for Interoperability classes. You can read the documentation here. The SOAP wizard can be accessed from the Server Actions menu. BPL and DTL classes can be edited textually. Support for the graphical editors will be added when they are rewritten using Angular. For a preview of how that would work, you can try out the new Angular Rule Editor in VS Code.

@Alexey Maslov 
That sounds like a bug to me. Can you file a GitHub issue with steps to reproduce? It would also help to know the versions of the extensions you have installed, the version of IRIS you're connected to, and the text of the file that you see the bug in.

@Menno Voerman 
Unfortunately I don't think this is possible. That command is for opening files, and technically the name of the file is "HS/FHIRServer/Interop.HTTPOperation.cls", not "HS.FHIRServer.Interop.HTTPOperation.cls".

@David Hockenbroch 
We just improved the UI for creating a new server-side editing workspace folder. If you have no workspace open, you can follow the steps here to create a new one. If you do, you can add a new folder to you workspace by right-clicking in the file explorer and selecting "Add Server Namespace to Workspace..". That command will follow steps 4 and on. To see CSP files, select "Web Application Files" in the menu from step 8. To see basic files, select "code files in <NS>", then select "Filter", then make sure your custom filter contains the "*.bas" pattern. It can include other file types as well.

@Martin Fukátko 
I tried reproducing your issue but couldn't. I see your using client-side editing (editing a local file). Have you saved that class on the server? The Language Server extension checks for class existence against the list of classes on the server so if yours hasn't been saved, it technically doesn't exist.

@Robert Cemper 
We currently don't have equivalents for Studio Wizards. There is a snippet for a %SQLQuery but not for %Query. Please file an enhancement request issue and we can consider adding a snippet or maybe a very simple UI.

@Ben Spead 
The existing docs here have been updated to reflect the new UI.

I expect that this will work fine. Our 'Open Error Location..." command just goes to the line+offset in the INT routine, it doesn't try to resolve the location in the CLS/MAC/CSP that generated the INT.

Here's a full list of all the MimeTypes that will be correctly colored in VS Code (requires InterSystems Langauge Server version 2.1.1):

• application/json
• text/html
• text/javascript
• text/css
• application/sql
• text/x-java-source
• application/python
• text/x-python
• text/xml
• application/xml

An XData bock with no MimeType will still be colored as XML.

@Rob Schoenmakers @Joel Solon

I just released InterSystems Language Server version 2.2.0, which provides intellisense for variables created by %New(), %Open() or %OpenId(). VS Code should auto-update it for you.
