# Set your terminal's color palette to match the Solarized color scheme by
# using escape sequences.  Uses OSC 4 to set colors.
#
# This will work with many terminal emulators, but not all.

set -o nounset

# This next line would set the colors in the 256 color pallette which normally approximate
# solarized.  Not a universal solution, but it helps with getting vim to look
# right! Stick this in your .vimrc just before "colorscheme solarized":
# let g:solarized_termtrans=1
# let g:solarized_termcolors=256
# See https://github.com/altercation/solarized/issues/8 for more information.
