Example #1
Source File: editor.ts    From starboard-notebook with Mozilla Public License 2.0 6 votes vote down vote up 
function tabKeyRun(t: { state: EditorState; dispatch: (transaction: Transaction) => void }): boolean {
  if (t.state.selection.ranges.some((r) => !r.empty)) {
    return indentMore({ state: t.state, dispatch: t.dispatch });
  }
  // So we can tab past the editor we don't tab if the cursor is at the very start of the document.
  // Note: this can be improved, we could instead see if we have pressed any keys since focusing the editor and decide
  // based on that.
  const r = t.state.selection.ranges[0];
  if (r && r.to === 0 && r.from === 0) {
    return false;
  }
  t.dispatch(
    t.state.update(t.state.replaceSelection("\t"), {
      scrollIntoView: true,
      annotations: Transaction.userEvent.of("input"),
    })
  );
  return true;
