October 2016 (version 1.7)

1.7.2 Recovery Build

We are releasing 1.7.2 today which includes a new version of the TypeScript Server (to 2.0.10). The update to the server will re-enable the Automatic Type Acquisition (ATA) feature by default for JavaScript users. This feature greatly improves the IntelliSense in JavaScript projects and removes the need to manually install TypeScript declaration files (.d.ts files). This feature is powered by a query to the npmjs service to retrieve relevant declaration files for used modules. More details in relation to this feature, including details on how to disable it are included in the relevant section of these release notes.

The 1.7.2 release also adds the final 1.7 translations and fixes several important issues.

1.7.1 Recovery Build

We are releasing a 1.7.1 recovery build to disable the automatic JavaScript typings file acquisition feature. We need to tune the acquisition to avoid unnecessary load on the NPM registry and we're working closely with the TypeScript and npmjs.org teams. We expect to enable this feature in a future release.

If you're curious about the details, you can read our blog post describing the event and NPM and VS Code's mitigations.

October Release Summary

Welcome to the October release of Visual Studio Code. There are a number of significant updates in this version that we hope you will like, some of the key highlights include:

The release notes are arranged in the following sections related to VS Code focus areas. Here are some further updates:

  • Workbench - Some View states now persisted in user settings. Open multiple files from Quick Open.
  • Editor - Keyboard shortcuts reference, finer formatting control.
  • Languages - JavaScript and CSS improvements.
  • Extensions - New categories for Keymaps and Formatters for easier search.
  • Node.js Debugging - Multi-target debugging support, new debugging settings.
  • Extension Authoring - Support for extension CHANGELOG.md files. Add to the editor tab context menu.

Workbench

Horizontal layout

You can now change the layout of editor groups to be either vertical or horizontal. Both layouts behave the same as before allowing you to move and resize editors and editor groups.

Horizontal

To enable horizontal layout for the current workspace, use:

  • The View menu Toggle Editor Group Layout.
  • The Command Palette Toggle Vertical/Horizontal Editor Group Layout.
  • An action in the header of the OPEN EDITORS view.

toggle horizontal layout

There is also a keyboard shortcut (kb(workbench.action.toggleEditorGroupLayout)) to quickly switch between the two layouts.

Once you made your choice for the layout, we persist it for the current workspace and restore it after restart.

Toggle Maximized Panel

We have introduced a global workbench command that maximizes the size of the panel (80% of the total height). If the panel is already maximized, this command will shrink the panel to its previous size. This is really handy when you have lots of output to review quickly. This command is not currently bound to any keyboard shortcut but you can add easily your own keybinding.

Toggle Sidebar and Hide Status Bar now persisted in user settings

We changed some of the toggles in the View menu to update your user settings file instead of persisting their state in the browser. This will make it easier to restore the same state on a different machine by copying the settings file.

The following settings will now be changed in your user settings file when you change them from the View menu:

  • workbench.sideBar.location to control the position of the Sidebar (left or right)
  • workbench.statusBar.visible to control the visibility of the Status Bar

In addition, changing the Zoom level from the View menu now writes to window.zoomLevel.

Open multiple files from Quick Open

Thanks to Will Prater (@wprater), you can now open multiple files from Quick Open by just pressing the Right arrow key. This will open the currently selected file in the background and you can continue selecting files from Quick Open.

Editor

Keyboard Shortcuts Reference

Help > Keyboard Shortcuts Reference brings up a printable PDF reference sheet of VS Code command keyboard shortcuts. Keep this reference handy and you'll be a VS Code power user in no time.

Here's it is for macOS:

Below are links to the three platform-specific versions:

Note: We also added a menu command to go to the Introductory Videos on code.visualstudio.com (Help > Introductory Videos).

Format Document / Format Selection

The editor now has two explicit format actions: Format Document (kb(editor.action.formatDocument)) and Format Selection (kb(editor.action.formatSelection)).

format on context menu

We also added new configuration options to enable/disable the default formatters for JavaScript, TypeScript, JSON, and HTML. Use these options when you have another extension installed that provides formatting for the same language.

We've added a new Formatters category to the Marketplace so you can easily search and find source code formatting extensions.

Languages

Better JavaScript IntelliSense

Note: This feature was disabled in the 1.7.1 build. Read on to learn what's coming in a future release.

VS Code uses the TypeScript language server to provide IntelliSense in JavaScript files. In the past, you had to create a jsconfig.json file. You also had to manually install typings (Type Declaration) files for all the modules and libraries you were using. That's not an easy chore, particularly when you are a pure JavaScript developer.

We talked with our friends on the TypeScript team and they came up with "Automatic Type Acquisition". ATA makes typings files almost invisible. A TypeScript language server that has ATA enabled watches your package.json files and automatically installs the typings files of all dependencies in a cache on your file system. It does the same when it finds references to well known client-side libraries. When you then invoke IntelliSense, the TypeScript server uses the typings files in the cache. The cache is shared between all your workspaces. Without a jsconfig.json file the TypeScript server assumes that everything in your workspace belongs to the same project.

We think this is so cool that we wanted you to get your hands on it as soon as possible. Our integration of ATA is still rough around the edges, but we decided to enable it by default. Should you experience issues, you can switch it off by setting typescript.disableAutomaticTypeAcquisition to true in your user settings.

Here are a few points you should be aware of when using ATA:

  • ATA is backward compatible. If you have a typings folder or you installed typings using npm, then those take precedence over the automatically acquired typings files.
  • ATA acquires the latest available version of the typings files. If you depend on an older version of a library or module then there can be discrepancies between the actual API exposed by the library or module and the API described in the typings file. If you require a specific version of a typings files, you can install it manually: npm install @types/<module name>@x.y.z.
  • An increasing number of npm modules bundle their typings files, meaning the only way to acquire the typings is by installing the module. ATA does not install npm modules for you, so you have to do it yourself.
  • There is a short delay between when a change is made to the dependencies in a package.json file and when the corresponding typings file is acquired and available for IntelliSense.
  • In the implementation, the ATA feature first queries npmjs for a module that includes a list of known declaration files. If your project includes any of these modules, their declaration files will be pulled down and added to the global cache.

CSS completions in HTML

You can now see CSS language features like code completion, validation and color annotation for CSS styles embedded within your HTML.

Improved TypeScript and JavaScript Grammar

TypeScript and JavaScript syntax highlighting is based on the TypeScript textmate grammar authored by the TypeScript team. In the recent months the grammar has been completely rewritten.

The main goal was to tackle as many of reported issues as possible. Additionally, we wanted to provide a better experience with existing color themes by generating scopes closer to what other popular JavaScript grammars such as the Atom grammar do, while still supporting features like the JavaScript React syntax.

As a result of the effort, over 100 issues has been fixed, including the request to report variable and function references. We decided to take advantage of the new scopes and now also colorize variable and function references in our Default Dark and Light Plus themes. We hope you like it!

Note: If you have already been helping us testing the latest grammar using the Latest TypeScript and JavaScript grammar extension: You can uninstall that extension now.

Linter Extensions

The vscode-eslint and vscode-tslint extensions now provide settings to automatically correct fixable warnings on save.

{
    "eslint.autoFixOnSave": true,
    "tslint.autoFixOnSave": true
}

Note: This setting is ignored when files.autoSave is set to afterDelay.

Extensions

Keymaps category

Keyboard shortcuts are vital to productivity and changing keyboarding habits can be tough. To help with this, we added two new extensions and introduced a new category Keymaps to the Marketplace. The purpose is to make it easier to switch between editors by removing the need to learn new keyboard shortcuts.

We built an extension for Atom and Sublime Text. We found some of the most popular keyboard shortcuts and would like your feedback on what we're missing. If we missed a keyboard shortcut, please open an issue or make a PR in the repo.

Keymaps

Additionally, you can create your own keymap extension using the keybindings contribution point and adding it to the Keymaps category.

Formatters category

Many extensions exist that contribute source code formatting functionality. Some of the most popular formatters have more than 100K installs! We wanted to make it easier for you to find formatters so we added a new category to the Marketplace called, naturally, Formatters. Search on the Marketplace and install a Formatter today.

Here are a couple of our favorites:

Disable extensions

Often you have more than one workspace and various extensions installed to support these workspaces. Most of the times, these extensions are exclusive to a single workspace and not needed for others. For example, if you have JavaScript and Go language workspaces, you do not need the JavaScript linting extension in a Go workspace and vice-versa. With this release, you can now run only those extensions which you think are necessary for a workspace and disable rest of them. You can also disable extensions for the complete VS Code application, if you do not want to uninstall them and do not want them to run.

Disable Extension

You can also disable or enable all extensions with few clicks from VS Code.

Disable All Extensions

Extension packs

Last release we introduced 'Extension Packs' which are extensions that depends on other extensions. In this release, we added a new tab to the extension editor to show these dependencies which gets installed when installing the pack.

Extension Pack

When you uninstall an extension pack, all its referenced dependency extensions are also uninstalled.

Node Debugging

Simplified launch configuration

In order to make setting up Node.js debugging as easy as possible, we've tried to simplify the initial 'launch.json' experience:

  • Required but rarely changed attributes are now rendered in gray to make it more obvious that there is no need to change them for the most common scenarios.
  • Less frequently used attributes (with good default values) were removed from the initial configurations to reduce the 'noise'. These attributes are still easily discoverable using IntelliSense.
  • Comments and a link to online documentation were added.
  • Online debugging documentation has been rewritten and improved.

launchjson

Note: Since we are only able to change the built-in Node.js debugger of VS Code, we are relying on the authors of the other debug extensions to do something similar (if needed).

Hit count conditional breakpoints

VS Code now supports setting a 'hit count condition' for a breakpoint (in addition to the 'expression condition' introduced some time ago). The 'hit count condition' controls how many times a breakpoint needs to be hit before it will 'break' execution.

HitCount

Whether a 'hit count condition' is respected and how the exact syntax of the expression looks like depends on the debugger extension used. In this milestone, only the built-in Node.js debugger supports hit counts (but we hope other debugger extensions will follow soon).

The hit count syntax supported by the Node.js debugger is either an integer or one of the operators <, <=, =, >, >=, % followed by an integer.

Some examples:

  • >10 break always after 10 hits
  • <3 break on the first two hits only
  • 10 same as >=10
  • %2 break on every other hit

Multiple target debugging

The October release contains an early implementation of 'multi target debugging', that is multiple debug sessions can be active at the same time within a single instance of VS Code (and a single project folder).

This feature helps with the following scenarios:

  • Debug an extension and its debug adapter and/or language server at the same time.
  • Debug a client and a server from a single project folder.
  • Debug a clustered program.

Note: In this milestone the focus was on getting the internal abstractions for multi target debugging right and not on how to surface this in a UI. So the UI of multi target debugging and how it is set up is highly experimental and will definitely change over the next milestones.

To enable 'multi target debugging' create a new launch configuration with a type composite and add an array typed attribute configurationNames. Under that attribute list the names of other launch configurations that should be launched in parallel.

After launching the composite configuration, the individual sessions show up as top level elements in the CALL STACK view. Actions (e.g. all actions in the floating debug widget) are always performed on the currently selected session in the CALL STACK view.

multiDebug

Debug settings

We have introduced the following new settings:

  • debug.allowBreakpointsEverywhere - Allows breakpoints to be set in any file (and not only in those which are explicitly registered). This is useful if you want to debug a new (transpiled) language with an existing debugger (for example, the Node.js debugger).
  • debug.openExplorerOnEnd - Controls if the Explorer should be automatically opened at the end of a debug session.

Extension Authoring

Breaking Change: MarkedString[] semantics

API related implementations which return MarkedString | MarkedString[] have changed semantics. Each MarkedString will be visually separated from the others with a horizontal line. Both the HoverProvider and Decoration APIs are affected by this.

Changelogs

You can now display your extension's CHANGELOG.md directly in the extension details view.

We recommend extension authors move any existing changelogs from their extension's README.md to a separate CHANGELOG.md file. Similar to README.md, if the CHANGELOG.md is placed in the extension's workspace root, it will be automatically included by the vsce publishing tool.

Provide menu entries for the editor tab context menu

We added an additional place where extensions can contribute menu entries, the context menu of an editor tab (this also works when tabs are disabled). The related menu path for contributing here is editor/title/context.

For example:

"commands": [{
    "command": "doSomething",
    "title": "Do Something"
}],
"menus": {
    "editor/title/context": [
        {
            "command": "doSomething"
        }
    ]
}

onDidChangeVisibleTextEditors event

We added an onDidChangeVisibleTextEditors event which fires whenever the list of visible editors changes.

Update Now: Using latest vscode.d.ts

As ever, the latest and greatest version of our extension API is defined in the vscode.d.ts file.

Note: when you update your extension to use an API version 1.7.0 or newer, make sure you use the latest version of the vscode-node-module (^1.0.3) and make sure to use TypeScript 2.0.

Please read here to learn how to migrate your existing extensions to the latest vscode module.
