# ------------
# Installation
# ------------
#
# First, assuming you've previously installed XQuartz from macosforge.com,
# unload and remove the existing launch agents:
#
#   $ sudo launchctl unload /Library/LaunchAgents/org.macosforge.xquartz.startx.plist
#   $ sudo launchctl unload /Library/LaunchDaemons/org.macosforge.xquartz.privileged_startx.plist
#   $ sudo rm /Library/LaunchAgents/org.macosforge.xquartz.startx.plist
#   $ sudo rm /Library/LaunchDaemons/org.macosforge.xquartz.privileged_startx.plist
#
# (You will need to log out for the above changes to take effect.)
#
# Then install xquartz from nixpkgs:
#
#   $ nix-env -i xquartz
#   $ xquartz-install
#
# You'll also want to add the following to your shell's profile (after you
# source nix.sh, so $NIX_LINK points to your user profile):
#
#   if [ "$(uname)" = "Darwin" -a -n "$NIX_LINK" -a -f $NIX_LINK/etc/X11/fonts.conf ]; then
#     export FONTCONFIG_FILE=$NIX_LINK/etc/X11/fonts.conf
#   fi

# A note about dependencies:
# Xquartz wants to exec XQuartz.app, XQuartz.app wants to exec xstart, and
# xstart wants to exec Xquartz, so we must bundle all three to prevent a cycle.
# Coincidentally, this also makes it trivial to install launch agents/daemons
# that point into the user's profile.
