Workbench

Support for Multi Root Workspaces

Support for multi-root workspaces is now enabled by default in the Stable release. This was our #1 feature request - it's been a while coming but it's here now.

Multi Root Workspaces

Please refer to our documentation for a full explanation of all of the multiple folder features: improvements to settings, our SCM experience, Tasks, Debugging and more.

NOTE: Extension authors should refer to our wiki that explains the new extension APIs to make your extension fully leverage multi-root workspaces.

Git status in File Explorer

To satisfy another very popular feature request, we added support to the File Explorer to show modified, added, conflicting, and ignored files in a different color and with a badge.

Move confirmation

The Git file decorations can be customized in many ways. You can hide the decorations entirely with the git.decorations.enabled setting and configure to only show colors explorer.decorations.colors or badges explorer.decorations.badges. There are new colors for theme authors which are prefixed with gitDecoration.

There is also a proposed API to allow extension authors to add color decorations to arbitrary resources. We haven't finalized on anything yet but are eager to learn how you would use decorations.

Vertical panels

Per popular user request, we now support a vertical panel layout. Using the actions Move to Right and Move to Bottom in the panel title bar, panels can switch between being displayed on the bottom or the right side.

Vertical Panel

Panel title bar improvements

We have improved the panel title bar such that it is now possible to rearrange and hide panels as well as added overflow support. Overflow with the Additional Views dropdown is particularly useful when the panels are docked vertically and have limited horizontal space.

Panel title

Blue logo for Stable

The VS Code logo for Stable releases is now blue again. You can read all about our icon journey in this blog post.

VS Code Logo

Note: Depending on your platform, you may still see the earlier logo due to operating system caching of the application icon.

Confirmations in File Explorer

We now present a confirmation dialog when moving files or folders in the File Explorer via drag and drop. This should prevent accidentally performing a move when not desired. If you don't want to see the confirmation dialog, you can configure explorer.confirmDragAndDrop to false.

Move confirmation

We also added a new setting, explorer.confirmDelete, to optionally hide our existing delete confirmation dialog.

Note: We will always show a confirmation dialog when deleting a file or folder will bypass your platform's trash bin.

Quick Open applies .gitignore exclusions

Quick Open (kb(workbench.action.quickOpen)) applies the exclusions from .gitignore files when enabled with the "search.useIgnoreFiles" setting.

Editor

Ctrl+D / Cmd+D improvements

Due to popular demand, the Add Selection to Next Find Match (kb(editor.action.addSelectionToNextFindMatch)) action has been modified to behave differently when you start adding multiple cursors with no selected text. In this case, the action will temporarily ignore the Find widget search options and will always search for whole words and case sensitive matches.

Navigate to next / previous symbolic highlight

Thanks to PR #35740 from Krzysztof Cieślak, it is now possible to navigate between highlighted symbols using kbstyle(F7) or kbstyle(Shift+F7) in languages where there is a semantic highlight provider. When you have a symbol selected, you can now quickly move to other instances of that symbol in your file.

Integrated Terminal

Faint text support

The terminal now supports the escape sequence for faint text:

Terminal faint text support

Unset environment keys

You can already set custom environment variables for Integrated Terminal sessions but now you can also clear existing variables by assigning them to null in the terminal.integrated.env.<platform> settings:

"terminal.integrated.env.linux": {
  "HOME": null
}

Improved Windows support

Windows support in the Integrated Terminal has been improved:

  • Deeply nested processes are now properly cleaned up after exiting the terminal session. This happened most frequently with servers launched from Node.js.
  • On Windows, the terminal received lines already wrapped so we don't know which lines are wrapped and which are separated by new lines. We now guess where lines are wrapped by checking the last character of the previous line and flag them as such. This fixes a problem with tasks where problem matchers would break on Windows and is also one of the prerequisites to get multiline links working on Windows.

Languages

TypeScript 2.6.1

VS Code 1.18 ships with TypeScript 2.6.1. This update provides VS Code with several exciting tooling improvements and also fixes a few bugs. You can read more about TypeScript 2.6 here.

Auto Import for JavaScript and TypeScript

Speed up your coding with auto imports for JavaScript and TypeScript. The suggestion list now includes all exported symbols in the current project. Just start typing:

Global symbols are now shown in the suggestion list

If you choose one of the suggestion from another file or module, VS Code will automatically add an import for it. In this example, VS Code adds an import for Hercules to the top of the file:

After selecting a symbol form a different file, an import is added for it automatically

Auto imports requires TypeScript 2.6+. You can disable auto imports by setting "typescript.autoImportSuggestions.enabled": false.

Localizable error messages and Quick Fix descriptions for JavaScript and TypeScript

JavaScript and TypeScript error messages and Quick Fix descriptions are now displayed in your current display language:

TypeScript errors using the display language

The "typescript.locale" setting lets you configure which language is used separately from your editor's display language. To revert to VS Code's 1.17 English only error messages, set "typescript.locale": "en".

Extract local refactoring for JavaScript and TypeScript

VS Code 1.18 adds several new JavaScript and TypeScript refactorings in addition to the extract method refactoring added in VS Code 1.16. The extract constant refactoring creates a new local variable for the currently selected expression:

When working with classes, you can also extract a value to a new property.

Install @types Quick Fix for TypeScript

TypeScript now offers a Quick Fix to npm install missing @types definitions for a given module:

This Quick Fix will install the @types definition locally and add it to the devDependencies in your package.json.

Additional typescript.tsc.autoDetect settings

VS Code automatically generates both build and build+watch tasks for all tsconfig.json files in your workspace. In VS Code 1.18, the typescript.tsc.autoDetect setting now lets you control which kinds of tasks are generated:

"typescript.tsc.autoDetect": "build" // only generate build tasks
"typescript.tsc.autoDetect": "watch" // only generate build+watch tasks
"typescript.tsc.autoDetect": "on"    // Generate both (default)
"typescript.tsc.autoDetect": "off"   // Don't generate tsconfig build tasks

Support for selectively enabling quick suggestions inside of strings and comments

Quick suggestions are disabled inside of strings and comments by default. In some cases, such as in JavaScript template strings, a string or comment may contain blocks of code where quick suggestions should be enabled. Grammars can now hint that VS Code should re-enable quick suggestions by adding a meta.embedded scope on tokens inside of a string or comment:

Quick suggestions in strings

JSON

JSON now supports JSON Schema Draft 06. The most notable additions are the const, contains and propertyNames properties. Read here for a more detailed overview of changes from draft 04.

Source Control

Inline change review

You can now review source code changes right within the standard editor. This feature depends on whether it is supported by the source code provider but it is already enabled for Git repositories out of the box.

Move confirmation

With this new UI, you can not only review your code changes but also navigate, stage or revert them inline.

Git: Conflict marker detection

When staging a file which is flagged as having conflicts due to a merge or rebase, VS Code will check for the standard merge markers (for example <<<<<<<) and alert you if you forget to delete them when you are about to stage the file.

Move confirmation

Git: Improved integration

Recently, there was a patch to Git which enables tools like VS Code to use git status without interfering with other concurrent Git commands. VS Code is now prepared for that upcoming Git change by using the right environment context (GIT_OPTIONAL_LOCKS) when spawning Git.

Extensions

Recommended extensions badge

Recommended extensions now display a badge to easily distinguish them from other extensions in a list. Hover on the badge or click the list item to learn why the extension was recommended to you.

Recommendation badges and reasons

Single view combining workspace and general recommendations

The two views for workspace recommended extensions and general recommended extensions are now combined into a single view with the two kinds of recommendations showing up in a split view. Use the command Extensions: Show Recommended Extensions to see this view.

There is also a handy Install All Workspace Recommendations command on the WORKSPACE RECOMMENDATIONS title bar to install all the extensions that are recommended by other users of your workspace.

You can edit workspace recommendations via the Configure Recommended Extensions (Workspace Folder) command in the same title bar.

Install or Configure Workspace Recommendations

Debugging

Debug in Status Bar

VS Code now shows the active debug launch configuration in the Status Bar. By clicking on the debug status, a user can change the active launch configuration and then start debugging without the need to open the Debug view.

Debug status

Focus actions

We have introduced new actions to easily move keyboard focus to the various Debug sections. This should make it easier for keyboard centric users to navigate while debugging.

These actions are:

  • Focus Variables: workbench.debug.action.focusVariablesView
  • Focus Watch: workbench.debug.action.focusWatchView
  • Focus CallStack: workbench.debug.action.focusCallStackView
  • Focus Breakpoints: workbench.debug.action.focusBreakpointsView

Start without debugging shortcut

The default keyboard shortcut on macOS for Debug: Start Without Debugging changed to kbstyle(Ctrl+F5) to avoid a collision with an existing macOS keyboard shortcut.

Coloring of Debug Console evaluation results based on type

Debug console expressions are now colored based on the type property returned from the debug extension. This is currently supported by the Node.js debug extension.

REPL Color

More WSL support for Node.js

A first glimpse of support for Node.js debugging in the Windows Subsystem for Linux (WSL) was already available in the previous milestone (but only for older versions of Node.js that still support the "legacy" protocol). In this milestone, another pull request by Bartosz Sosnowski (@bzoz) was integrated that adds support for the "inspector" protocol that is used by more recent versions of Node.js. With this update, it is now possible to run Node.js v8 in WSL.

Tasks

Schema improvements

The schema for the tasks.json file version 2.0.0 was updated. The taskName property is deprecated in favor of the label property to make it more consistent with contributed tasks. In addition, there is now a snippet for new tasks. By default, it creates a task of type shell to execute commands in the Integrated Terminal.

workspaceFolder replaces workspaceRoot

Last release, we deprecated the ${workspaceRoot} variable in favor of ${workspaceFolder} to make this consistent with multi-root workspace support. For the same reason, we are deprecating ${workspaceRootFolderName}. Please use ${workspaceFolderBasename} instead. This deprecation applies to debug launch configurations as well.

Performance improvements

Faster editor decorations

Decorations are a fundamental editor concept on which numerous features are built; for example: find matches highlights, diff annotations, word highlights, selection highlights, breakpoints, folding markers, and inline colors. Moreover, numerous extensions make use of decorations to customize the rendering of VS Code's editor. Below is a screenshot with various editor decorations highlighted:

Editor Decorations

PR #36410 reimplements editor decorations as a delta-encoded Interval Tree (an augmented Red-Black tree). Besides reducing the time spent in all operations related to decorations (creating, updating, deleting or querying), the change also brings in some impressive memory usage savings. As an immediate result of these optimizations, we have increased the in-file on type find limit from 1,000 matches to 20,000 matches.

Windows start-up

We are always on the lookout for ways to improve VS Code start-up time. During the last month, we made a variety of improvements that significantly decreased the time of the initial (cold) launch of VS Code.

Extension Authoring

Configuration: Listen to specific changes

Now Configuration change event provides a ConfigurationChangeEvent object that has a method affectsConfiguration to check about configuration changes. You can also check if a configuration has changed for a resource.

/**
 * An event describing the change in Configuration
 */
export interface ConfigurationChangeEvent {

    /**
     * Returns `true` if the given section for the given resource (if provided) is affected.
     *
     * @param section Configuration name, supports _dotted_ names.
     * @param resource A resource Uri.
     * @return `true` if the given section for the given resource (if provided) is affected.
     */
    affectsConfiguration(section: string, resource?: Uri): boolean;
}

Async Input Box validation

The showInputBox function now supports asynchronous validation. Call showInputBox like so:

vscode.window.showInputBox({
  async validateInput(value) {
    return await someLongRunningOperation(value);
  }
});

Folder icons in File Icon Themes

File Icon themes can now disable the default folder icon (the rotating triangle) in tree views and use the folder icons to indicate the expansion state:

Explorer without twisties

To do so, File Icon themes must specify "hidesExplorerArrows":true in the File Icon theme definition file. Thanks to Ari for the PR.

New Context: resourceExtname

There is a new context key to control keybindings and menu items. Its name is resourceExtname and its value will be the extension of the file in question.

New workspace.name property

A new workspace.name property was added that provides (readonly) access to the name of the workspace. The name will be undefined if no workspace is opened.

SCM: New menu: scm/change/title

Along with the new SCM inline change review, a new contributable menu context is now available: scm/change/title. It allows you to contribute commands to the header of an inline change review view.

Move confirmation

Terminal: Setting environment

You can now set the environment of terminal instances launched via the extension API:

window.createTerminal({
  name: 'My session',
  shell: 'zsh',
  env: {
    JAVA_HOME: '<path>'
  }
});

Debug API updates

Command debug.logToDebugConsole is deprecated

With the introduction of a proper vscode.debug.console.append(...) API in the October release, it is no longer necessary to use the debug.logToDebugConsole command to append text to the debug console. Due to that we are deprecating the debug.logToDebugConsole command and plan to drop support for it in the future. If it is difficult for you to move off this feature, please speak up by commenting here.

Note: Currently this API is proposed, so in order to use it you must opt into it by adding a "enableProposedApi": true to package.json and you'll have to copy the vscode.proposed.d.ts into your extension project. Also be aware that you cannot publish an extension to the Marketplace that uses the enableProposedApi attribute.

Command vscode.startDebug has been removed

As announced in the previous release, we have finally removed support for the vscode.startDebug command.

Command vscode.workbench.customDebugRequest has been removed

As announced in the previous release, we have finally removed support for the vscode.workbench.customDebugRequest command.

Debug contributions in package.json

Activation event onDebug:type has been removed

As announced in the previous release, we have finally removed support for the onDebug:type activation event.

Using debuggers.startSessionCommand in package.json has been removed

As announced in the previous release, we have finally removed support for the startSessionCommand command.

Using command with debuggers.initialConfigurations in package.json is deprecated

As announced in the previous release, we have finally removed support for the initialConfigurations command.

Updated documentation and mock-debug example

With this release, most of the command based debug API has been replaced by the proper API available through vscode.d.ts. Consequently, we have updated both the documentation for debug extensions and the underlying mock-debug example for the new APIs.

New commands

Key Command Command id
kb(workbench.action.quickOpenPreviousEditor) Open quick file picker with the second entry selected by default workbench.action.quickOpenPreviousEditor
kb(workbench.action.openFolderAsWorkspaceInNewWindow) Open a folder as workspace in a new window workbench.action.openFolderAsWorkspaceInNewWindow
