Today "with-option foo bar command-that-fails" fails with Error: 1:1: 'evaluate-commands': 1:1: 'with-option': 2:5: 'evaluate-commands': 4:9: 'evaluate-commands': 1:2: 'no-such-command': no such command but leaks the option value. Fix this by resetting the option and rethrowing the error. Unfortunately the original stack trace is lost (questionable behavior inherited from C++?).

# 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
|
|
#

Possible values:

- "window" (default) - new window

This executes "%opt{windowing_module}-terminal-%opt{windowing_placement}" with the given arguments.
|
|
If the windowing module is 'wayland', 'sway' or 'x11', then the 'termcmd' option is used as terminal program.

Example usage:

|
|
terminal sh
|
|
with-option windowing_placement horizontal terminal sh
