# originally written by "mhwombat": https://bbs.archlinux.org/viewtopic.php?id=71938&p=2
# Based on "snippy" by "sessy"
# (https://bbs.archlinux.org/viewtopic.php?id=71938)
#
# You will also need "dmenu", "zenity", "xsel" and "xdotool". Get them from your linux
# distro in the usual way.
#
# To use:
# 1. Create the directory ~/.snippy
#
# 2. Create a file in that directory for each snippet that you want.
#    The filename will be used as a menu item, so you might want to
#    omit the file extension when you name the file.
#
#    TIP: If you have a lot of snippets, you can organise them into
#    subdirectories under ~/.snippy.
#
#    TIP: The contents of the file will be pasted asis, so if you
#    don't want a newline at the end when the text is pasted, don't
#    put one in the file.
#
# 3. Bind a convenient key combination to this script.
#
#    TIP: If you're using XMonad, add something like this to xmonad.hs
#      ((mod4Mask, xK_s), spawn "/path/to/snippy")
#
# 4. Set variables in ~/.snippy.conf. for example
#    MENU_ENGINE="dmenu"
#    DMENU_ARGS=' -p snippy -fn arial -sf green'
#    ZENITY_ARGS='--list --hide-header --column=Snippet --text=snippy'
#    GUIPASTE="xdotool key ctrl+v"
#    CLIPASTE="xdotool key ctrl+shift+v"

# smarty like template engine which executes inline bash in (bashdown) strings (replaces variables with values e.g.)

# @example: echo 'hi $NAME it is $(date)' | bashdown
# fetches a document and interprets bashsyntax in string (bashdown) templates

This snippy actually works best for me, other snippy.sh scripts keep pasting other clipboard content previously copied.

Thanks!
