# This scripts provides a default configuration for tmux-copyrat options and key bindings.
# It is run only once at tmux launch.
#
# Each option and binding can be overridden in your `tmux.conf` by defining options like
#
#   set -g @copyrat-keytable "foobar"
#   set -g @copyrat-keyswitch "z"
#   set -g @copyrat-match-bg "magenta"
#
# and bindings like
#
#   bind-key -T foobar h new-window -d -n "[copyrat]" '/path/to/tmux-copyrat --window-name "[copyrat]" --pattern-name urls'
#                        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
#
# changing this will probably break integration     -
#
# Just make sure you first open a named window in the background and provide that name to tmux-copyrat.
#
# Don't even try to run tmux-copyrat with run-shell, this cannot work because Tmux launches these processes
# without attaching them to a pty.

# You could also entirely ignore this file (not even source it) and define all options and bindings
# in your `tmux.conf`.
