# bm.sh — shell wrapper for bmrk (bash / zsh)
#
# For fish, use bm.fish instead — fish has its own function-file format and
# cannot source this file.
#
# The TUI renders to stderr (visible in terminal); stdout carries the path.
# This wrapper captures stdout, and if it is a directory, cd's to it.
# All other output (help, version, bookmark list, confirmations) is printed normally.
#
# INSTALLATION
# ────────────
# bash / zsh — add ONE of these lines to ~/.bashrc or ~/.zshrc:
#
#   source /path/to/bm.sh
#
#   — or inline (no extra file needed):
#
#   bm() { local r x="$PWD"; if [ "$1" = "-" ]; then [ -n "$BMRK_PREV_DIR" ] && { cd "$BMRK_PREV_DIR" && BMRK_PREV_DIR="$x"; } || { echo "bm: no previous directory" >&2; return 1; }; return; fi; r=$(bmrk "$@"); if [ -n "$r" ] && [ -d "$r" ]; then cd "$r" && BMRK_PREV_DIR="$x"; elif [ -n "$r" ]; then echo "$r"; fi; }
#
# After editing your shell config, reload it:
#   source ~/.bashrc    # bash
#   source ~/.zshrc     # zsh

bm() {
    local result prev_dir="$PWD"

    # Return to previous directory
    if [ "$1" = "-" ]; then
        if [ -n "$BMRK_PREV_DIR" ] && [ -d "$BMRK_PREV_DIR" ]; then
            cd "$BMRK_PREV_DIR" || return 1
            BMRK_PREV_DIR="$prev_dir"
        else
            echo "bm: no previous directory" >&2
            return 1
        fi
        return
    fi

    result=$(bmrk "$@")
    local exit_code=$?

    if [ -n "$result" ] && [ -d "$result" ]; then
        cd "$result" || return 1
        BMRK_PREV_DIR="$prev_dir"
    elif [ -n "$result" ]; then
        echo "$result"
    fi

    return $exit_code
}
