# You will also need "dmenu", "zenity", "xsel", "sponge" 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")
