# Attempt to detect the windowing environment we're operating in
#
# We try to load modules from the windowing_modules str-list option in order,
# stopping when one of the modules loads successfully. This ensures that only
# a single module is loaded by default.
#
# On load each module must attempt to detect the environment it's appropriate
# for, and if the environment isn't appropriate it must fail with an error.
# In addition, each module must check for the length of the windowing_modules
# str-list option defined below, and must /not/ check for an appropriate
# environment if the list is empty. An example of this test:
#
# evaluate-commands %sh{
#     [ -z "${kak_opt_windowing_modules}" ] || [ -n "$TMUX" ] || echo 'fail tmux not detected'
# }
#
# Each module is expected to define at least two aliases:
#  * terminal - create a new terminal with sensible defaults
#  * focus - focus the specified client, defaulting to the current client
#
