vscode namespace API

Executes the command denoted by the given command identifier.

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 classes defined in this API. 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 application name of the editor, like 'VS Code'.

• readonly

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

• readonly

A unique identifier for the computer.

• readonly

A unique identifier for the current session. Changes each time the editor is started.

• readonly

All extensions currently known to the system.

Get an extension by its full identifier in the form of: publisher.name.

Get an extension its full identifier in the form of: publisher.name.

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 text document is disposed.

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

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 root.

When there is no workspace root or when the path is not a child of that folder, the input is returned.

Creates a file system watcher.

A glob pattern that filters the file events 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 can be watched.

Find files in the workspace.

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

Get a 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.

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.

This function will be called for each visible code lens, usually when scrolling and after calls to compute-lenses.

Arguments that the command handler should be invoked with.

Creates a new completion item.

An optional command that is executed after inserting this completion. Note that additional modifications to the current document should be described with the additionalTextEdits-property.

A human-readable string with additional information about this item, like type or symbol information.

A human-readable string that represents a doc-comment.

A string that should be used when filtering a set of completion items. When falsy the label is used.

Note: The range must be a single line and it must contain the position at which completion has been requested.

A string that should be used when comparing this item with other items. When falsy the label is used.

• deprecated - Deprecated in favor of CompletionItem.insertText and CompletionItem.range.

An edit which is applied to a document when selecting this completion. When an edit is provided the value of insertText is ignored.

The range of the edit must be single-line and on the same line completions were requested at.

Provide completion items for the given position and document.

Given a completion item fill in more data, like doc-comment or details.

The editor will only resolve a completion item once.
