# hy — per-prompt history logger + search shortcut for zsh
#
# Source this file from ~/.zshrc:
#     source /path/to/hy.zsh
#
# Logs every command to a daily file:
#     ~/.logs/history-YYYY-MM-DD.log
# Format (tab-delimited, exactly one line per command):
#     TIMESTAMP \t PWD \t COMMAND
# where any tabs/newlines inside COMMAND are encoded as the two-char sequences
# \t and \n so each entry stays single-line and unambiguous.
#
# Defines:
#     __hy_log — runs before every prompt; logs the just-executed command
#                (registered via add-zsh-hook so it coexists with oh-my-zsh,
#                starship, prezto, your own precmd, etc.)
#     hy       — grep across all daily log files (chronological)
#     hyr      — same as hy but newest match first
