示例1: record
function record(change: Delta, contents: Delta, oldContents: Delta, selection: Selection, oldSelection: Selection) {
const timestamp = Date.now();
const action = getAction(change);
stack.redo.length = 0;
let undoChange = contents.diff(oldContents);
// Break combining if actions are different (e.g. a delete then an insert should break it)
if (!action || lastAction !== action) cutoff();
lastAction = action;
if (lastRecorded && (!options.delay || lastRecorded + options.delay > timestamp) && stack.undo.length > 0) {
// Combine with the last change
const entry = stack.undo.pop();
oldSelection = entry.undoSelection;
undoChange = undoChange.compose(entry.undo);
change = entry.redo.compose(change);
} else {
lastRecorded = timestamp;
}
stack.undo.push({
redo: change,
undo: undoChange,
redoSelection: selection,
undoSelection: oldSelection,
});
if (stack.undo.length > options.maxStack) {
stack.undo.shift();
}
