Functions ​

FunctionDescription

chainCommands

Combines multiple command functions into a single command that executes them sequentially until one succeeds.

This function creates a command that tries each provided command in order. The first command that returns true (indicating success) will stop the chain, and the chained command will return true. If all commands return false, the chained command returns false.

This is particularly useful for creating fallback behavior where you want to try multiple strategies for handling a user action.

Example

typescript
// Create a command that tries to delete selection, then join backward, then select backward
const myBackspaceCommand = chainCommands(
  deleteSelection,
  joinBackward,
  selectNodeBackward,
);

// Use in a keymap
const keymap = {
  Backspace: chainCommands(deleteSelection, joinBackward),
};
