vscode namespace API

Executes the command denoted by the given command identifier.

• Note 1: When executing an editor command not all types are allowed to be passed as arguments. Allowed are the primitive types string, boolean, number, undefined, and null, as well as Position, Range, Uri and Location.
• Note 2: There are no restrictions when executing commands that have been contributed by extensions.

Retrieve the list of all available commands. Commands starting an underscore are treated as internal commands.

Registers a command that can be invoked via a keyboard shortcut, a menu item, an action, or directly.

Registering a command with an existing command identifier twice will cause an error.

Registers a text editor command that can be invoked via a keyboard shortcut, a menu item, an action, or directly.

Text editor commands are different from ordinary commands as they only execute when there is an active editor when the command is called. Also, the command handler of an editor command has access to the active editor and to an edit-builder.

The currently active debug console.

The currently active debug session or undefined. The active debug session is the one represented by the debug action floating window or the one currently shown in the drop down menu of the debug action floating window. If no debug session is active, the value is undefined.

List of breakpoints.

An event which fires when the active debug session has changed. Note that the event also fires when the active debug session changes to undefined.

An event that is emitted when the set of breakpoints is added, removed, or changed.

An event which fires when a custom DAP event is received from the debug session.

An event which fires when a new debug session has been started.

An event which fires when a debug session has terminated.

Add breakpoints.

Register a debug configuration provider for a specifc debug type. More than one provider can be registered for the same type.

Remove breakpoints.

Start debugging by using either a named launch or named compound configuration, or by directly passing a DebugConfiguration. The named configurations are looked up in '.vscode/launch.json' found in the given folder. Before debugging starts, all unsaved files are saved and the launch configurations are brought up-to-date. Folder specific variables used in the configuration (e.g. '${workspaceFolder}') are resolved against the given folder.

The application name of the editor, like 'VS Code'.

• readonly

The application root folder from which the editor is running.

• readonly

Represents the preferred user-language, like de-CH, fr, or en-US.

Create a diagnostics collection.

Return the identifiers of all known languages.

Compute the match between a document selector and a document. Values greater than zero mean the selector matches the document.

A match is computed according to these rules:

1. When DocumentSelector is an array, compute the match for each contained DocumentFilter or language identifier and take the maximum value.
2. A string will be desugared to become the language-part of a DocumentFilter, so "fooLang" is like { language: "fooLang" }.
3. A DocumentFilter will be matched against the document by comparing its parts with the document. The following rules apply:
   1. When the DocumentFilter is empty ({}) the result is 0
   2. When scheme, language, or pattern are defined but one doesn’t match, the result is 0
   3. Matching against * gives a score of 5, matching via equality or via a glob-pattern gives a score of 10
   4. The result is the maximun value of each match

Samples:

// default document from disk (file-scheme)
doc.uri; //'file:///my/file.js'
doc.languageId; // 'javascript'
match('javascript', doc); // 10;
match({language: 'javascript'}, doc); // 10;
match({language: 'javascript', scheme: 'file'}, doc); // 10;
match('*', doc); // 5
match('fooLang', doc); // 0
match(['fooLang', '*'], doc); // 5

// virtual document, e.g. from git-index
doc.uri; // 'git:/my/file.js'
doc.languageId; // 'javascript'
match('javascript', doc); // 10;
match({language: 'javascript', scheme: 'git'}, doc); // 10;
match('*', doc); // 5

An event that is emitted when the configuration changed.

An event that is emitted when a text document is changed. This usually happens when the contents changes but also when other things like the dirty-state changes.

An event that is emitted when a workspace folder is added or removed.

An event that is emitted when a text document is disposed.

To add an event listener when a visible text document is closed, use the TextEditor events in the window namespace. Note that this event is not emitted when a TextEditor is closed but the document remains open in another visible text editor.

An event that is emitted when a text document is opened.

To add an event listener when a visible text document is opened, use the TextEditor events in the window namespace. Note that:

• The event is emitted before the document is updated in the active text editor
• When a text document is already open (e.g.: open in another visible text editor) this event is not emitted

An event that is emitted when a text document is saved to disk.

An event that is emitted when a text document will be saved to disk.

Note 1: Subscribers can delay saving by registering asynchronous work. For the sake of data integrity the editor might save without firing this event. For instance when shutting down with dirty files.

Note 2: Subscribers are called sequentially and they can delay saving by registering asynchronous work. Protection against misbehaving listeners is implemented as such:

• there is an overall time budget that all listeners share and if that is exhausted no further listener is called
• listeners that take a long time or produce errors frequently will not be called anymore

The current thresholds are 1.5 seconds as overall time budget and a listener can misbehave 3 times before being ignored.

Make changes to one or many resources as defined by the given workspace edit.

When applying a workspace edit, the editor implements an 'all-or-nothing'-strategy, that means failure to load one document or make changes to one document will cause the edit to be rejected.

Returns a path that is relative to the workspace folder or folders.

When there are no workspace folders or when the path is not contained in them, the input is returned.

Creates a file system watcher.

A glob pattern that filters the file events on their absolute path must be provided. Optionally, flags to ignore certain kinds of events can be provided. To stop listening to events the watcher must be disposed.

Note that only files within the current workspace folders can be watched.

Find files across all workspace folders in the workspace.

• sample - findFiles('**/*.js', '**/node_modules/**', 10)

Get a workspace configuration object.

When a section-identifier is provided only that part of the configuration is returned. Dots in the section-identifier are interpreted as child-access, like { myExt: { setting: { doIt: true }}} and getConfiguration('myExt.setting').get('doIt') === true.

When a resource is provided, configuration scoped to that resource is returned.

Returns the workspace folder that contains a given uri.

• returns undefined when the given uri doesn't match any workspace folder
• returns the input when the given uri is a workspace folder itself

Opens a document. Will return early if this document is already open. Otherwise the document is loaded and the didOpen-event fires.

The document is denoted by an uri. Depending on the scheme the following rules apply:

• file-scheme: Open a file on disk, will be rejected if the file does not exist or cannot be loaded.
• untitled-scheme: A new file that should be saved on disk, e.g. untitled:c:\frodo\new.js. The language will be derived from the file name.
• For all other schemes the registered text document content providers are consulted.

Note that the lifecycle of the returned document is owned by the editor and not by the extension. That means an onDidClose-event can occur at any time after opening it.

A short-hand for openTextDocument(Uri.file(fileName)).

• see - openTextDocument

Opens an untitled text document. The editor will prompt the user for a file path when the document is to be saved. The options parameter allows to specify the language and/or the content of the document.

Register a task provider.

Register a text document content provider.

Only one provider can be registered per scheme.

Save all dirty files.

This method replaces deleteCount workspace folders starting at index start by an optional set of workspaceFoldersToAdd on the vscode.workspace.workspaceFolders array. This "splice" behavior can be used to add, remove and change workspace folders in a single operation.

If the first workspace folder is added, removed or changed, the currently executing extensions (including the one that called this method) will be terminated and restarted so that the (deprecated) rootPath property is updated to point to the first workspace folder.

Use the onDidChangeWorkspaceFolders() event to get notified when the workspace folders have been updated.

Example: adding a new workspace folder at the end of workspace folders

workspace.updateWorkspaceFolders(workspace.workspaceFolders ? workspace.workspaceFolders.length : 0, null, { uri: ...});

Example: removing the first workspace folder

workspace.updateWorkspaceFolders(0, 1);

Example: replacing an existing workspace folder with a new one

workspace.updateWorkspaceFolders(0, 1, { uri: ...});

It is valid to remove an existing workspace folder and add it again with a different name to rename that folder.

Note: it is not valid to call updateWorkspaceFolders() multiple times without waiting for the onDidChangeWorkspaceFolders() to fire.
