#!/usr/bin/env bash
# Open a dmenu which prompts for any number of whitespace-separated search terms and suggests old
# queries.
# Grep iteratively in a certain hard coded file for lines that contain all of the given search
# terms and the special term '#snippet'.
# From these lines, the trimmed parts before the '#snippet' are presented in a second dmenu pass
# from which the user can select one.
# The raw selected item will be written to the system clipboard.
# This is a neat way of querying and retrieving snippets into any desktop environment.
