Show HN: A shell-native cd-compatible directory jumper using power-law frecency
Summary
Show HN discusses SD-switchdir, a shell-native directory jumper that uses a power-law frecency ranking over a visit history to determine the best directory matches for cd-like navigation. It supports multiple shells (ksh, bash, zsh) and offers a companion ds for inspection, with configurable memory window and log retention to balance recency and history.
