CompletionProvider

The completion provider interface defines how extensions should communicate code completion suggestions in CodeEdit.

Registering a Completion Provider

codeedit.extensions.registerCompletionProvider(myCompletionProvider)

CompletionProvider Interface

class CompletionProvider {
  provideCompletionItems(editor, context) {
    ...
    
    return completionItems;
  }
}

It is expected that every CompletionProvider class include a provideCompletionItems method, the role of which is to return an array of CompletionItem objects. This array of objects is used to determine relevant completion suggestions as the user types inside the editor.

In the case of the CompletionProvider, the provideCompletionItems method will be called each time the user types in the editor while the activation event conditions are met. CodeEdit will then determine the relevant suggestions.

The provideCompletionItems method expects an editor and context as arguments. These objects provide the extension with information about the state when a completion is triggered, including the scope of the current cursor position.

Using the context object, additional completion criteria can be defined by limiting the results returned by the provideCompletionItems method based on the current context. For example, a completion suggestion that is a CSS class name, should only be returned when the current context is within a valid HTML class attribute.
