What happens when there are multiple formatters for one language? This can be a problem when different formatters' actions contradict. Likewise, the editor will disable the formatting actions when displaying documents for which no formatter is registered. With that information, the editor can enable the formatting actions when for example, an HTML document is open. When an extension registers as a formatter with registerDocumentFormattingEditProvider, it indicates with a DocumentSelector which programming languages it supports. Multiple FormattersĪ common misunderstanding is that when contributing a formatter, you must support all programming languages. Tip: To take advantage of this, a formatting extension needs to be registered using the registerDocumentFormattingEditProvider API call. An extension properly implementing the formatting API supports this feature without any new code. Recently, we added the "Format on Save" feature. registerCommand ( 'extension.format-foo', () => ) □ formatter implemented as separate command vscode. The best practice is to use the formatting API and not create a new action, such as "Format Foo File." The full extension example can be found on GitHub. The code snippets below show what to do and what not to do when implementing a formatter. Using the API leads to a consistent user experience across all formatter extensions. These actions are available in the editor context menu, bound to keyboard shortcuts, and visible in the Command Palette. The core benefit of using the extension API for implementing a formatter comes from the exposure of the Format Document and Format Selection actions. The common pattern is for VS Code to provide the UI around a feature and the extensions provide the necessary data to make it shine. The essence of these principles is that VS Code provides the skeleton and extensions provide the "smarts". VS Code's extension API follows a set of guiding principles. We wrote this blog to explain the best practices for implementing formatters. The first language extensions we built, for example TypeScript, C# and Go, used the formatting API. Novemby Johannes Rieken, its introduction, the Visual Studio Code extension API has provided support for source code formatters.
