Variables

read onlyfs:FileSystem

A {@link FileSystem file system} instance that allows to interact with local and remote files, e.g. vscode.workspace.fs.readDirectory(someUri) allows to retrieve all entries of a directory or vscode.workspace.fs.stat(anotherUri) returns the meta data for a file.

read onlyisTrusted:Bool

When true, the user has explicitly trusted the contents of the workspace.

read onlyname:Null<String>

The name of the workspace. undefined when no workspace has been opened.

Refer to https://code.visualstudio.com/docs/editor/workspaces for more information on the concept of workspaces.

read onlynotebookDocuments:ReadOnlyArray<NotebookDocument>

All notebook documents currently known to the editor.

read onlyonDidChangeConfiguration:Event<ConfigurationChangeEvent>

An event that is emitted when the {@link WorkspaceConfiguration configuration} changed.

finalonDidChangeNotebookDocument:Event<NotebookDocumentChangeEvent>

An event that is emitted when a {@link NotebookDocument notebook} has changed.

read onlyonDidChangeTextDocument:Event<TextDocumentChangeEvent>

An event that is emitted when a {@link TextDocument text document} is changed. This usually happens when the {@link TextDocument.getText contents} changes but also when other things like the {@link TextDocument.isDirty dirty}-state changes.

read onlyonDidChangeWorkspaceFolders:Event<WorkspaceFoldersChangeEvent>

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

Note: this event will not fire if the first workspace folder is added, removed or changed, because in that case the currently executing extensions (including the one that listens to this event) will be terminated and restarted so that the (deprecated) rootPath property is updated to point to the first workspace folder.

read onlyonDidCloseNotebookDocument:Event<NotebookDocument>

An event that is emitted when a {@link NotebookDocument notebook} is disposed.

Note 1: There is no guarantee that this event fires when an editor tab is closed.

Note 2: A notebook can be open but not shown in an editor which means this event can fire for a notebook that has not been shown in an editor.

read onlyonDidCloseTextDocument:Event<TextDocument>

An event that is emitted when a {@link TextDocument text document} is disposed or when the language id of a text document {@link languages.setTextDocumentLanguage has been changed}.

Note 1: There is no guarantee that this event fires when an editor tab is closed, use the {@linkcode window.onDidChangeVisibleTextEditors onDidChangeVisibleTextEditors}-event to know when editors change.

Note 2: A document can be open but not shown in an editor which means this event can fire for a document that has not been shown in an editor.

read onlyonDidCreateFiles:Event<FileCreateEvent>

An event that is emitted when files have been created.

Note: This event is triggered by user gestures, like creating a file from the explorer, or from the {@linkcode workspace.applyEdit}-api, but this event is not fired when files change on disk, e.g triggered by another application, or when using the {@linkcode FileSystem workspace.fs}-api.

read onlyonDidDeleteFiles:Event<FileDeleteEvent>

An event that is emitted when files have been deleted.

Note 1: This event is triggered by user gestures, like deleting a file from the explorer, or from the {@linkcode workspace.applyEdit}-api, but this event is not fired when files change on disk, e.g triggered by another application, or when using the {@linkcode FileSystem workspace.fs}-api.

Note 2: When deleting a folder with children only one event is fired.

read onlyonDidGrantWorkspaceTrust:Event<Void>

Event that fires when the current workspace has been trusted.

read onlyonDidOpenNotebookDocument:Event<NotebookDocument>

An event that is emitted when a {@link NotebookDocument notebook} is opened.

read onlyonDidOpenTextDocument:Event<TextDocument>

An event that is emitted when a {@link TextDocument text document} is opened or when the language id of a text document {@link languages.setTextDocumentLanguage has been changed}.

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

  • The event is emitted before the {@link TextDocument document} is updated in the {@link window.activeTextEditor active text editor}
  • When a {@link TextDocument text document} is already open (e.g.: open in another {@link window.visibleTextEditors visible text editor}) this event is not emitted

read onlyonDidRenameFiles:Event<FileRenameEvent>

An event that is emitted when files have been renamed.

Note 1: This event is triggered by user gestures, like renaming a file from the explorer, and from the {@linkcode workspace.applyEdit}-api, but this event is not fired when files change on disk, e.g triggered by another application, or when using the {@linkcode FileSystem workspace.fs}-api.

Note 2: When renaming a folder with children only one event is fired.

finalonDidSaveNotebookDocument:Event<NotebookDocument>

An event that is emitted when a {@link NotebookDocument notebook} is saved.

read onlyonDidSaveTextDocument:Event<TextDocument>

An event that is emitted when a {@link TextDocument text document} is saved to disk.

read onlyonWillCreateFiles:Event<FileWillCreateEvent>

An event that is emitted when files are being created.

Note 1: This event is triggered by user gestures, like creating a file from the explorer, or from the {@linkcode workspace.applyEdit}-api. This event is not fired when files change on disk, e.g triggered by another application, or when using the {@linkcode FileSystem workspace.fs}-api.

Note 2: When this event is fired, edits to files that are are being created cannot be applied.

read onlyonWillDeleteFiles:Event<FileWillDeleteEvent>

An event that is emitted when files are being deleted.

Note 1: This event is triggered by user gestures, like deleting a file from the explorer, or from the {@linkcode workspace.applyEdit}-api, but this event is not fired when files change on disk, e.g triggered by another application, or when using the {@linkcode FileSystem workspace.fs}-api.

Note 2: When deleting a folder with children only one event is fired.

read onlyonWillRenameFiles:Event<FileWillRenameEvent>

An event that is emitted when files are being renamed.

Note 1: This event is triggered by user gestures, like renaming a file from the explorer, and from the {@linkcode workspace.applyEdit}-api, but this event is not fired when files change on disk, e.g triggered by another application, or when using the {@linkcode FileSystem workspace.fs}-api.

Note 2: When renaming a folder with children only one event is fired.

finalonWillSaveNotebookDocument:Event<NotebookDocumentWillSaveEvent>

An event that is emitted when a {@link NotebookDocument notebook 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 {@link NotebookDocumentWillSaveEvent.waitUntil 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.

read onlyonWillSaveTextDocument:Event<TextDocumentWillSaveEvent>

An event that is emitted when a {@link TextDocument 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 {@link TextDocumentWillSaveEvent.waitUntil 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.

read onlyrootPath:Null<String>

Deprecated: "Use `workspace.workspaceFolders` instead."
Deprecated:

Use {

The uri of the first entry of {@linkcode workspace.workspaceFolders workspaceFolders} as string. undefined if there is no first entry.

Refer to https://code.visualstudio.com/docs/editor/workspaces for more information on workspaces.

@linkcode workspace.workspaceFolders workspaceFolders} instead.

read onlytextDocuments:ReadOnlyArray<TextDocument>

All text documents currently known to the editor.

read onlyworkspaceFile:Null<Uri>

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 is opened the path of the workspace file as Uri otherwise. if the workspace is untitled, the returned URI will use the untitled: scheme

The location can e.g. be used with the vscode.openFolder command to open the workspace again after it has been closed.

Example:

vscode.commands.executeCommand('vscode.openFolder', uriOfWorkspace);

Refer to https://code.visualstudio.com/docs/editor/workspaces for more information on the concept of workspaces.

Note: it is not advised to use workspace.workspaceFile to write configuration data into the file. You can use workspace.getConfiguration().update() for that purpose which will work both when a single folder is opened as well as an untitled or saved workspace.

read onlyworkspaceFolders:Null<ReadOnlyArray<WorkspaceFolder>>

List of workspace folders (0-N) that are open in the editor. undefined when no workspace has been opened.

Refer to https://code.visualstudio.com/docs/editor/workspaces for more information on workspaces.

Methods

applyEdit(edit:WorkspaceEdit, ?metadata:Null<WorkspaceEditMetadata>):Thenable<Bool>

Make changes to one or many resources or create, delete, and rename resources as defined by the given {@link WorkspaceEdit workspace edit}.

All changes of a workspace edit are applied in the same order in which they have been added. If multiple textual inserts are made at the same position, these strings appear in the resulting text in the order the 'inserts' were made, unless that are interleaved with resource edits. Invalid sequences like 'delete file a' -> 'insert text in file a' cause failure of the operation.

When applying a workspace edit that consists only of text edits an 'all-or-nothing'-strategy is used. A workspace edit with resource creations or deletions aborts the operation, e.g. consecutive edits will not be attempted, when a single edit fails.

@link WorkspaceEditMetadata metadata} for the edit.

Parameters:

edit

A workspace edit.

metadata

Optional {

Returns:

A thenable that resolves when the edit could be applied.

asRelativePath(pathOrUri:EitherType<String, Uri>, ?includeWorkspaceFolder:Bool):String

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

When there are no {@link workspace.workspaceFolders workspace folders} or when the path is not contained in them, the input is returned.

@link Uri.fsPath fsPath} is used.

Parameters:

pathOrUri

A path or uri. When a uri is given its {

includeWorkspaceFolder

When true and when the given path is contained inside a workspace folder the name of the workspace is prepended. Defaults to true when there are multiple workspace folders and false otherwise.

Returns:

A path relative to the root or the input.

createFileSystemWatcher(globPattern:GlobPattern, ?ignoreCreateEvents:Bool, ?ignoreChangeEvents:Bool, ?ignoreDeleteEvents:Bool):FileSystemWatcher

Creates a file system watcher that is notified on file events (create, change, delete) depending on the parameters provided.

By default, all opened {@link workspace.workspaceFolders workspace folders} will be watched for file changes recursively.

Additional paths can be added for file watching by providing a {@link RelativePattern} with a base path to watch. If the path is a folder and the pattern is complex (e.g. contains ** or path segments), it will be watched recursively and otherwise will be watched non-recursively (i.e. only changes to the first level of the path will be reported).

Note that paths that do not exist in the file system will be monitored with a delay until created and then watched depending on the parameters provided. If a watched path is deleted, the watcher will suspend and not report any events until the path is created again.

If possible, keep the use of recursive watchers to a minimum because recursive file watching is quite resource intense.

Providing a string as globPattern acts as convenience method for watching file events in all opened workspace folders. It cannot be used to add more folders for file watching, nor will it report any file events from folders that are not part of the opened workspace folders.

Optionally, flags to ignore certain kinds of events can be provided.

To stop listening to events the watcher must be disposed.

Note that file events from recursive file watchers may be excluded based on user configuration. The setting files.watcherExclude helps to reduce the overhead of file events from folders that are known to produce many file changes at once (such as .git folders). As such, it is highly recommended to watch with simple patterns that do not require recursive watchers where the exclude settings are ignored and you have full control over the events.

Note that symbolic links are not automatically followed for file watching unless the path to watch itself is a symbolic link.

Note that the file paths that are reported for having changed may have a different path casing compared to the actual casing on disk on case-insensitive platforms (typically macOS and Windows but not Linux). We allow a user to open a workspace folder with any desired path casing and try to preserve that. This means: if the path is within any of the workspace folders, the path will match the casing of the workspace folder up to that portion of the path and match the casing on disk for children if the path is outside of any of the workspace folders, the casing will match the case of the path that was provided for watching In the same way, symbolic links are preserved, i.e. the file event will report the path of the symbolic link as it was provided for watching and not the target.

Examples

The basic anatomy of a file watcher is as follows:

const watcher = vscode.workspace.createFileSystemWatcher(new vscode.RelativePattern(<folder>, <pattern>));

watcher.onDidChange(uri => { ... }); // listen to files being changed
watcher.onDidCreate(uri => { ... }); // listen to files/folders being created
watcher.onDidDelete(uri => { ... }); // listen to files/folders getting deleted

watcher.dispose(); // dispose after usage

Workspace file watching

If you only care about file events in a specific workspace folder:

vscode.workspace.createFileSystemWatcher(new vscode.RelativePattern(vscode.workspace.workspaceFolders[0], '**​/*.js'));

If you want to monitor file events across all opened workspace folders:

vscode.workspace.createFileSystemWatcher('**​/*.js');

Note: the array of workspace folders can be empty if no workspace is opened (empty window).

Out of workspace file watching

To watch a folder for changes to *.js files outside the workspace (non recursively), pass in a Uri to such a folder:

vscode.workspace.createFileSystemWatcher(new vscode.RelativePattern(vscode.Uri.file(<path to folder outside workspace>), '*.js'));

And use a complex glob pattern to watch recursively:

vscode.workspace.createFileSystemWatcher(new vscode.RelativePattern(vscode.Uri.file(<path to folder outside workspace>), '**​/*.js'));

Here is an example for watching the active editor for file changes:

vscode.workspace.createFileSystemWatcher(new vscode.RelativePattern(vscode.window.activeTextEditor.document.uri, '*'));

@link GlobPattern glob pattern} that controls which file events the watcher should report.

Parameters:

globPattern

A {

ignoreCreateEvents

Ignore when files have been created.

ignoreChangeEvents

Ignore when files have been changed.

ignoreDeleteEvents

Ignore when files have been deleted.

Returns:

A new file system watcher instance. Must be disposed when no longer needed.

findFiles(include:GlobPattern, ?exclude:GlobPattern, ?maxResults:Int, ?token:Null<CancellationToken>):Thenable<Array<Uri>>

Find files across all {@link workspace.workspaceFolders workspace folders} in the workspace.

@example findFiles('**​/.js', '​/node_modules/*', 10)

@link GlobPattern glob pattern} that defines the files to search for. The glob pattern will be matched against the file paths of resulting matches relative to their workspace. Use a {@link RelativePattern relative pattern} to restrict the search results to a {@link WorkspaceFolder workspace folder}. @link GlobPattern glob pattern} that defines files and folders to exclude. The glob pattern will be matched against the file paths of resulting matches relative to their workspace. When undefined, default file-excludes (e.g. the files.exclude-setting but not search.exclude) will apply. When null, no excludes will apply. @link workspace.workspaceFolders workspace folders} are opened.

Parameters:

include

A {

exclude

A {

maxResults

An upper-bound for the result.

token

A token that can be used to signal cancellation to the underlying search engine.

Returns:

A thenable that resolves to an array of resource identifiers. Will return no results if no {

getConfiguration(?section:String, ?scope:ConfigurationScope):WorkspaceConfiguration

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 scope is provided configuration confined to that scope is returned. Scope can be a resource or a language identifier or both.

Parameters:

section

A dot-separated identifier.

scope

A scope for which the configuration is asked for.

Returns:

The full configuration or a subset.

getWorkspaceFolder(uri:Uri):Null<WorkspaceFolder>

Returns the {@link WorkspaceFolder 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

Parameters:

uri

An uri.

Returns:

A workspace folder or undefined

openNotebookDocument(uri:Uri):Thenable<NotebookDocument>

openNotebookDocument(notebookType:String, ?content:NotebookData):Thenable<NotebookDocument>

Open a notebook. Will return early if this notebook is already {@link notebookDocuments loaded}. Otherwise the notebook is loaded and the {@linkcode onDidOpenNotebookDocument}-event fires.

Note that the lifecycle of the returned notebook is owned by the editor and not by the extension. That means an {@linkcode onDidCloseNotebookDocument}-event can occur at any time after.

Note that opening a notebook does not show a notebook editor. This function only returns a notebook document which can be shown in a notebook editor but it can also be used for other things.

@link NotebookDocument notebook}

Parameters:

uri

The resource to open.

Returns:

A promise that resolves to a {

openTextDocument(uri:Uri):Thenable<TextDocument>

openTextDocument(?options:{language:Null<String>, content:Null<String>}):Thenable<TextDocument>

openTextDocument(path:String):Thenable<TextDocument>

Opens a document. Will return early if this document is already open. Otherwise the document is loaded and the {@link workspace.onDidOpenTextDocument didOpen}-event fires.

The document is denoted by an {@link Uri}. Depending on the {@link Uri.scheme scheme} the following rules apply: file-scheme: Open a file on disk (openTextDocument(Uri.file(path))). Will be rejected if the file does not exist or cannot be loaded. untitled-scheme: Open a blank untitled file with associated path (openTextDocument(Uri.file(path).with({ scheme: 'untitled' }))). The language will be derived from the file name. * For all other schemes contributed {@link TextDocumentContentProvider text document content providers} and {@link FileSystemProvider file system providers} are consulted.

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

@link TextDocument document}.

Parameters:

uri

Identifies the resource to open.

Returns:

A promise that resolves to a {

registerFileSystemProvider(scheme:String, provider:FileSystemProvider, options:{isReadonly:Null<Bool>, isCaseSensitive:Null<Bool>}):Disposable

A notebook serializer must be contributed through the notebooks extension point. When opening a notebook file, the editor will send the onNotebook:<notebookType> activation event, and extensions must register their serializer in return.

@link Disposable} that unregisters this serializer when being disposed.

Parameters:

notebookType

A notebook.

serializer

A notebook serialzier.

options

Optional context options that define what parts of a notebook should be persisted

Returns:

A {

Returns:

A {

save(uri:Uri):Thenable<Null<Uri>>

Saves the editor identified by the given resource and returns the resulting resource or undefined if save was not successful or no editor with the given resource was found.

Note that an editor with the provided resource must be opened in order to be saved.

Parameters:

uri

the associated uri for the opened editor to save.

Returns:

A thenable that resolves when the save operation has finished.

saveAll(?includeUntitled:Bool):Thenable<Bool>

Save all dirty files.

Parameters:

includeUntitled

Also save files that have been created during this session.

Returns:

A thenable that resolves when the files have been saved. Will return false for any file that failed to save.

saveAs(uri:Uri):Thenable<Null<Uri>>

Saves the editor identified by the given resource to a new file name as provided by the user and returns the resulting resource or undefined if save was not successful or cancelled or no editor with the given resource was found.

Note that an editor with the provided resource must be opened in order to be saved as.

Parameters:

uri

the associated uri for the opened editor to save as.

Returns:

A thenable that resolves when the save-as operation has finished.

updateWorkspaceFolders(start:Int, deleteCount:Null<Int>, workspaceFoldersToAdd:Rest<{uri:Uri, name:Null<String>}>):Bool

This method replaces deleteCount {@link workspace.workspaceFolders 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.

Note: in some cases calling this method may result in the currently executing extensions (including the one that called this method) to be terminated and restarted. For example when the first workspace folder is added, removed or changed the (deprecated) rootPath property is updated to point to the first workspace folder. Another case is when transitioning from an empty or single-folder workspace into a multi-folder workspace (see also: https://code.visualstudio.com/docs/editor/workspaces).

Use the {@linkcode onDidChangeWorkspaceFolders 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 {@link updateWorkspaceFolders updateWorkspaceFolders()} multiple times without waiting for the {@linkcode onDidChangeWorkspaceFolders onDidChangeWorkspaceFolders()} to fire.

@link WorkspaceFolder workspace folders} from which to start deleting workspace folders.

Parameters:

start

the zero-based location in the list of currently opened {

deleteCount

the optional number of workspace folders to remove.

workspaceFoldersToAdd

the optional variable set of workspace folders to add in place of the deleted ones. Each workspace is identified with a mandatory URI and an optional name.

Returns:

true if the operation was successfully started and false otherwise if arguments were used that would result in invalid workspace folder state (e.g. 2 folders with the same URI).
