Editor:
Stable CodeLens:
VS Code now optimistically caches CodeLens locations and restores them immediately after switching editors. This fixes an issue where CodeLens lines would shift slightly when switching between editors.
Languages:
Lower rank for CSS property values with vendor prefix:
CSS property values prefixed with dash '-' (such as -moz-grid or -ms-grid), now come after grid in auto completion.
Debugging:
debug.showSubSessionsInToolBar
We have introduced the setting debug.showSubSessionsInToolBar which controls whether the debug sub-sessions are shown in the debug tool bar. When this setting is false, the stop command on a sub-session will also stop the parent session. This setting default is false.
Tasks:
Terminate all tasks:
The Tasks: Terminate Task command has a new option to terminal all tasks if there are multiple tasks running. If this is an action you do often, you can create a keyboard shortcut for the command with the terminateAll argument.
Automatically show Problems panel:
The new revealProblems task property allows you to automatically show the Problems panel. The property values are always, never, and onProblem.
Contributions to extensions:
Preview: Remote Development:
Note: The Remote Development extensions require Visual Studio Code Insiders.
Visual Studio Code Remote Development allows you to use a container, remote machine, or the Windows Subsystem for Linux (WSL) as a full-featured development environment.
The extensions in the Remote Development extension pack run in the context of the remote workspace while VS Code feels like it does when you run locally.
Vetur:
The Vetur extension now offers semantic diagnostics, hover information, jump to definition, and find references for the JavaScript expression inside Vue's template interpolation region
Other improvements include reduced memory usage and import path completion. You can learn more about them in the Vetur changelog.
Extension authoring:
Multi-extension debugging:
In this milestone, we've added support for debugging more than one extension at a time. This is useful if you are developing a set of tightly coupled or interdependent extensions.
Previously this feature was only surfaced via the command-line interface of VS Code, now the argument --extensionDevelopmentPath can be specified more than once. Typically --extensionDevelopmentPath is used in the launch configuration of an extension. When developing more than one extension, we recommend combining the individual extension projects into a multi-folder workspace and create a new launch configuration (stored in the workspace .code-workspace file) that uses multiple --extensionDevelopmentPath arguments for the individual extensions.
Please note that in this release, it is not possible to create a preLaunchTask that builds both extensions by combining the preLaunchTasks of the individual extension projects.
Command links in notifications:
It was always possible to include links in notification messages via the syntax [link name](
http://link), but this only worked for links that open in a browser. Now you can also invoke a command from a link with the syntax [link name](command:<command id>). The command with the provided identifier will be triggered when the user clicks the link.
Links in notifications allow for title:
You can now add a title to links in notifications that will be shown when the user hovers over the link. The syntax is [link name](link "<the title>").
Proposed extension APIs:
Every milestone comes with new proposed APIs and extension authors can try them out. As always we are keen on your feedback. This is what you have to do to try out a proposed API:
You must use Insiders because proposed APIs change frequently.
You must have this line in the package.json file of your extension: "enableProposedApi": true.
Copy the latest version of the vscode.proposed.d.ts file into your project.
Note that you cannot publish an extension that uses a proposed API. We may likely make breaking changes in the next release and we never want to break existing extensions.
vscode.workspace.workspaceFile:
There is a new workspace property returning the location of the workspace file. For example: file:///Users/name/Development/myProject.code-workspace or untitled:1555503116870 for a workspace that is untitled and not yet saved.
Depending on the workspace that is opened, the value will be:
undefined when no workspace or a single folder is opened.
The path of the workspace file as Uri.
If the workspace is untitled, the returned URI will use the untitled: scheme.
One use of the workspace file location is to call the vscode.openFolder command to open the workspace again after it has been closed:
vscode.commands.executeCommand('vscode.openFolder', uriOfWorkspace);
Note: It is not recommended using the workspace.workspaceFile location to write configuration data directly into the file. You can use workspace.getConfiguration().update() which will work both when a single folder is opened as well as an untitled or saved workspace.
Machine-specific settings
If you have settings that allow users to customize an executable path and if these paths need to be scoped to the machine they are running on, you can now classify such settings as machine scoped. Extension authors set the scope property when contributing to the configuration extension point. Machine-specific settings can only be configured for User settings.
Engineering:
Rewritten filesystem provider for local files:
Extensions ave been able to provide their own filesystem implementations for custom resources (read more here). However, VS Code's own implementation for local files was not implemented with the same extension APIs. This resulted in subtle differences when dealing with local file resources compared to resources coming from extensions. Over the last two milestones, we rewrote our local file system provider to use the extension APIs for consistency.
New documentation:
Python Azure Functions:
There is a new Deploy Python to Azure Functions tutorial that describes how to create and deploy Python serverless Azure Functions.
Miscellaneous:
Language Server Protocol:
The Language Server Protocol has proposed support for the following new features:
Selection ranges: to compute selection ranges for an array of positions. Sent from client to server.
Call hierarchy: to compute a call hierarchy for a given symbol. Sent from client to server.
Progress: to initiate progress reporting from the server. Sent from server to client.
The new features are available in the next versions of the vscode-languageclient and vscode-languageserver npm modules.
Notable fixes:
Explorer Respects Trash Capability from FileSystemProvider
Call Stack "Paused On Breakpoint" UI not visible for long thread names
Terminal window crashes in Mac OS
Debug Console render newlines unnecessary
Scrolling in debug window is behaving strange
Error revealing files in the explorer
Report issue’ button on ‘Running extensions’ causes tens of duplicate issues
