ui/CommandHistory¶

Classes¶

CommandHistory¶

CommandHistory - the console's persisted command history with up/down-arrow navigation, extracted from Console so the navigation semantics are testable without a DOM.

Navigation model: a null index means "fresh input line". previous() walks toward older commands and sticks at the oldest (no cycling); next() walks toward newer commands and finally returns to the fresh line (empty string).
