-# Description:
-# Script enabling keyboard-based dmenu copy/paste between multiple different
-# st/surf instances. Designed to be used in combination with the surf & st
-# externalpipe-signal patches.
-#
-# Note: by default assumes you've patched both st & surf for SIGUSR1 with
-# signal patches and shares 1 buffer for convience. Comment if using just st or surf.
-#
-# Upon executing dmenu_copy/dmenu_type, SIGUSR1 is sent to st & surf.
-# St/surf then additionally call this script w/ "{surf,st}_strings_read" arg.
-# This loads up the $BUFFER_FILE (FIFO or file) with the contents filtered
-# for what should appear in dmenu. If using (BUFFER_FILE_FIFO=true), dmenu
-# is then immediatedly invoked reading from $BUFFER_FILE as STDIN; if not
-# using a FIFO, BUFFER_FILE_R_DELAY is waited on before reading file / invoking dmenu.
-#
-# Highly reccomended for quick feedback: set BUFFER_FILE_FIFO=true & use dmenu
-# non_blocking_stdin patch: tools.suckless.org/dmenu/patches/non_blocking_stdin/
-#
-# Install:
-# - Add script to $PATH
-# - Use "externalpipe_buffer.sh dmenu_type" as a hotkey (in surf/st/wm).
-# - Use "externalpipe_buffer.sh st_strings_read" as st externalpipe-signal command.
-# - Use "externalpipe_buffer.sh surf_strings_read" as surf externalpipe-signal command.
