The tmux-terminal commands typically run
tmux split-window kak -c ${kak_session} </dev/null >/dev/null 2>&1 &
The tmux process runs in the background with output silenced. This is
not necessary because "tmux split-window" is a thin client that
merely forwards its arguments to the tmux server. All our wrappers
for other terminal-servers (kitty, iterm, screen, wezterm, zellij)
simply run in the foreground, not silencing any errors.
The tmux backgrounding was added in 208b91627 (Move client.kak as
x11.kak and change tmux.kak to be its peer, 2015-11-17), probably for
consistency with x11.kak. That one is different however because it
potentially spawns a full terminal, not just a client that briefly
talks to a terminal server - that's why x11-terminal needs to use
"setsid," to avoid killing said terminal when we signal our process
group.
Remove the backgrounding from tmux.kak for consistency and to reduce
surprise.
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++?).
Today I can control "terminal" and "new" by changing the terminal
alias but I always need to choose a concrete implementation, like
"tmux-terminal-horizontal", even when there is otherwise no need to
mention tmux in my config.
Allow to configure windowing system and window placement independently
by introducing dedicated options.
This allows to create mappings that work in any windowing system like
map global user c %{:with-option windowing_placement window new<ret>}
map global user '"' %{:with-option windowing_placement vertical new<ret>}
map global user '%' %{:with-option windowing_placement horizontal new<ret>}
For windowing systems that don't support all placements, you can wrap
the above in try/catch to fall back on the "window" variant which is
defined for all windowing systems.
When using multiple (nested) windowing systems, you might want to
add mappings like
map global user t %{:with-option windowing_module tmux new<ret>}
map global user T %{:with-option windowing_module wayland new<ret>}

This changes the default "terminal" alias for some modules. In
particular, instead of delegating to
iterm-terminal-vertical
screen-terminal-vertical
tmux-terminal-horizontal
wezterm-terminal-vertical
it will now by default delegate to the respective "-window" variant.
We could maintain backwards compatiblity here by setting the
"windowing_placement" option accordingly, but the new behavior seems
more logical?
Also, this removes the "terminal-tab" alias which was only defined
by the kitty module.
We could try to keep the alias approach and implement a "with-alias"
command, however that approach can only capture both dimensions
(windowing system and placement) if we add tons of commands
like "terminal-horizontal" (with implied windowing system) and
"tmux-terminal" (with implied placement).
Side thought: we could also get rid of the "focus" alias and instead
define
define-command focus %{
"%opt{windowing_module}-focus"
}
Closes#3943, #4425
The x11-terminal command spawns a potentially long-lived terminal
process. The terminal can is completely independent of the Kakoune
session that created it.
Due to how it's implemented, the spawned terminals will have
environment variables "kak_opt_termcmd" and "kak_quoted_reg_a"
set. This can be surprising, especially since, by convention, the
environment contains no lowercase variables. Let's stop exporting them.
When launch matches using `id` kitty tries to match against tab id
before matching windows. When there are multiple tabs it's likely to
match a tab before matching a window.
Use `window_id` directly to avoid any possiblity of matching tabs.
This is only needed for `kitty @ launch` for other commands there is
no specific `window_id` field.
Before, sed would add quotes to every line of the single multiline argument,
causing the final quoted argument to "split ... command" or screen to contain
unquoted newlines such as this (from kakoune-cr):
tell application "iTerm"
tell current session of current window
tell (split vertically with same profile command "env PATH='...' 'sh' '-c' ''
' export KAKOUNE_SESSION=$1'
' export KAKOUNE_CLIENT=$2'
' shift 3'
''
' [ $# = 0 ] && set \"$SHELL\"'
''
' \"sh\"'
' ' '--' '51909' 'client0' 'terminal' ") to select
end tell
end tell
Instead of using sed to do this which operates on single lines at a time, simply
use printf to insert ' quotes before and after the entire argument.
Just like the parent commit but for tmux-repl-* commands.
Note that tmux-repl-set-pane without arguments is kind of broken; it
increments the current pane ID, which only works in the most basic
scenarios. We should probably replace it with something better,
with menu completions etc.
The tmux-terminal-window command always spawns windows in the tmux
session where the Kakoune session was started - even if the calling
Kakoune client lives in a different tmux session.
Fix this by always creating the window in the tmux
session of the calling client. We already do the same for
tmux-terminal-{horizontal,vertical}.
I call tmux-terminal-impl with "new-window -a" (instead of
"new-window"), so make sure the fix works for my use case.
I considered retrieving the tmux session ID from the $TMUX environment
variable but the tmux manpage only specifies that $TMUX contains
"some internal data".
A pane's ID is immutable for the lifetime of the tmux server.
Same with window/session IDs.
When creating a new tmux repl, we record all three IDs to later use
them to send text to the repl.
The window/session IDs can be invalidating when a pane is moved to
a different window/session (via "tmux move-pane", "tmux move-window"
etc). This will cause repl-send-text to fail.
Fix this by dropping the redundant and potentially incorrect
window/session IDs. The immutable pane ID is enough.
tmux-send-text would silently fail when the repl is no more. Let's
instead print an error, pointing the user to the *debug* buffer which
has tmux' stderr.
While Wayland offers nothing general to help us support `focus` on all
window managers, WM-specific implementations are generally possible.
Sway is a tiling window manager that mimics i3, and has a reasonably
powerful CLI that can help us achieve this.
In addition to supporting `focus` for Sway, this change paves the way
for additional WM-specific Wayland functionality by adding a detection
step to wayland.kak, in a similar fashion to detection.kak.
currently focus client doesn't work if target pane of the client is in different tab or window from current one.
select window, select tab should be triggered in order to select a pane on a currently not focused tab or window.
