To fuzzy search through passwords managed with passage, I’ve written the following script that is inspired by the upstream version which is using fzf.

fd --type=file --base-directory="${PASSAGE_DIR:-${HOME}/.passage/store}" .age --exec echo '{.}' | \
  sk --cycle --layout=reverse --tiebreak=score --no-multi | \
  xargs --replace --max-args=1 --no-run-if-empty \
    passage show --clip=1 {}

This version requires fd, skim, xargs, and passage itself of course. The detailed breakdown on how it works is as follows:

1. Use fd to find all files within ${PASSAGE_DIR} that end in .age. Each password in passage is inside that folder and has such a file extensions, therefore we are selecting every password we have.
2. Using both --base-directory and --exec echo '{.}' ensures that passwords are returned in such form that they can be passed back into passage again. The placeholder '{.}' is a feature provided by fd which strips the file extension from each returned value.
3. All passwords are then passed into sk to allow to fuzzy search across them all. Setting --no-multi ensures that only a single password can be selected.
4. Finally, xargs calls passage and replaces the curly braces with the selected password. Thanks to --clip=1, the first line in the selected password entry will be copied to the clipboard and automatically cleared after 45 seconds.

To call that script, I’ve saved it as passage-fuzzy-search.sh in my .local/bin folder and added some checks into it to verify that every required software is actually installed.

#!/usr/bin/env zsh

if ! (( ${+commands[passage]} )); then
    echo 'passage not installed. Please install passage.'
    exit
fi
if ! (( ${+commands[sk]} )); then
    echo 'sk not installed. Please install skim.'
    exit
fi
if ! (( ${+commands[fd]} )); then
    echo 'fd not installed. Please install fd-find.'
    exit

fd --type=file --base-directory="${PASSAGE_DIR:-${HOME}/.passage/store}" .age --exec echo '{.}' | \
  sk --cycle --layout=reverse --tiebreak=score --no-multi | \
  xargs --replace --max-args=1 --no-run-if-empty \
    passage show --clip=1 {}

Since typing passage-fuzzy-search.sh is way too long, I have added an alias like this:

alias pp='passage-fuzzy-search.sh'
