clipmenu is a simple clipboard manager using dmenu and xsel. Launch this
when you want to select a clip.

All arguments are passed through to dmenu itself.

Environment variables:

- $CM_LAUNCHER: specify a dmenu-compatible launcher (default: dmenu)
- $CM_DIR: specify the base directory to store the cache dir in (default: $XDG_RUNTIME_DIR, $TMPDIR, or /tmp)
EOF
    exit 0
fi

if [[ "$CM_LAUNCHER" == rofi ]]; then
    # rofi supports dmenu-like arguments through the -dmenu flag
    set -- -dmenu "$@"
fi

# It's okay to hardcode `-l 8` here as a sensible default without checking
# whether `-l` is also in "$@", because the way that dmenu works allows a later
# argument to override an earlier one. That is, if the user passes in `-l`, our
# one will be ignored.
chosen_line=$(
    cat "$cache_file_prefix"_* /dev/null | sort -rnk 1 | cut -d' ' -f2- |
        awk '!seen[{{&blob}}]++' | "$CM_LAUNCHER" -l 8 "$@"
)

[[ $chosen_line ]] || exit 1

file=$cache_dir/$(cksum <<< "$chosen_line")

if ! [[ -f "$file" ]]; then
    # We didn't find this in cache
    printf 'FATAL: %s not in cache\n' "$chosen_line" >&2
    exit 2
fi

    xsel --logfile /dev/stderr -i --"$selection" < "$file"
