|
# 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"
|
