pane-border-status is set to "top" or "bottom" (rather than "off"),
every pane has a permanent top or bottom border containing the text from
pane-border-format.
Based on a diff sent long ago by Jonathan Slenders, mostly rewritten and
simplified by me.
uint64_t and converting UTF-8 to Unicode on input and the reverse on
output. (This allows key bindings, there are still omissions - the
largest being that the various prompts do not accept UTF-8.)
around, we can't use file descriptors for the working directory because
we will be unable to pass it to a privileged process to tell it where to
read or write files or spawn children. So move tmux back to using
strings for the current working directory. We try to check it exists
with access() when it is set but ultimately fall back to ~ if it fails
at time of use (or / if that fails too).
the main loop after events that may have changed the pane, but do so at
most once every 500 millis. If the pane changed too soon, use a timer to
ensure that a check happens later.
can't do the name check every loop, because that is too expensive, and
we can't make sure it only happens infrequently because we have no idea
when the next change will happen.
but that can only happen when we have already been woken up by a read
event, so there is no need for a timer, we can just check the changed
flag on the end of that read event (we already loop over the windows to
check for bells etc anyway).
a notification which will get confused because the reference count is
already zero and end up back in window_destroy and a double
free. Instead, just destroy the layouts directly. Noticed by Thomas
Adam.
server at a time; it may be toggled or cleared with select-pane -m and
-M (the border is highlighted). A new target '~' or '{marked}' specifies
the marked pane to commands and it is the default target for the
swap-pane and join-pane -s flag (this makes them much simpler to use -
mark the source pane and then change to the target pane to run swapp or
joinp).
multiple times, also remove the default space in window_flags and use a
conditional to add it in window-status-format (this means additional
flags can be added in the option without extra spaces). From Thomas Adam
with tweaks by me.
options for "mouse-this" and "mouse-that", mouse events may be bound as
keys and there is one option "mouse" that turns on mouse support
entirely (set -g mouse on).
See the new MOUSE SUPPORT section of the man page for description of the
key names and new flags (-t= to specify the pane or window under mouse
as a target, and send-keys -M to pass through a mouse event).
The default builtin bindings for the mouse are:
bind -n MouseDown1Pane select-pane -t=; send-keys -M
bind -n MouseDown1Status select-window -t=
bind -n MouseDrag1Pane copy-mode -M
bind -n MouseDrag1Border resize-pane -M
To get the effect of turning mode-mouse off, do:
unbind -n MouseDrag1Pane
unbind -temacs-copy MouseDrag1Pane
The old mouse options are now gone, set-option -q may be used to
suppress warnings if mixing configuration files.
split-window, respawn-window or respawn-pane, pass them directly to
execvp() to help avoid quoting problems. One argument still goes to "sh
-c" like before. Requested by many over the years. Patch from J Raynor.
irritating flaws:
a) The old way of always using the top or left if the choice is
ambiguous is annoying when the layout is unbalanced.
b) The new way of remembering the last used pane is annoying if the
layout is balanced and the leftmost is obvious to the user (because
clearly if we go right from the top-left in a tiled set of four we want
to end up in top-right, even if we were last using the bottom-right).
So instead, use a combination of both: if there is only one possible
pane alongside the current pane, move to it, otherwise choose the most
recently used of the choice.
options with a single foo-style option. For example:
set -g status-fg yellow
set -g status-bg red
set -g status-attr blink
Becomes:
set -g status-style fg=yellow,bg=red,blink
The -a flag to set can be used to add to rather than replace a style. So:
set -g status-bg red
Becomes:
set -ag status-style bg=red
Currently this is fully backwards compatible (all *-{fg,bg,attr} options
remain) but the plan is to deprecate them over time.

descriptors rather than strings.
- Each session still has a current working directory.
- New sessions still get their working directory from the client that
created them or its attached session if any.
- New windows are created by default in the session working directory.
- The -c flag to new, neww, splitw allows the working directory to be
overridden.
- The -c flag to attach let's the session working directory be changed.
- The default-path option has been removed.
To get the equivalent to default-path '.', do:
bind c neww -c $PWD
To get the equivalent of default-path '~', do:
bind c neww -c ~
This also changes the client identify protocol to be a set of messages rather
than one as well as some other changes that should make it easier to make
backwards-compatible protocol changes in future.
When clearing WINLINK_ALERTFLAGS for all sessions, we must also, for
that window, clear the window->flags as well, otherwise sessions may
well still see flags for winlinks long since cleared.
This therefore introduces WINDOW_ALERTFLAGS to help with this.

window or unzoom (restored to the normal layout) if it already zoomed,
bound to C-b z by default. The pane is unzoomed on pretty much any
excuse whatsoever.
We considered making this a new layout but the requirements are quite
different from layouts so decided it is better as a special case. Each
current layout cell is saved, a temporary one-cell layout generated and
all except the active pane set to NULL.
Prompted by suggestions and scripts from several. Thanks to Aaron Jensen
and Thiago Padilha for testing an earlier version.

Fix up window reference counting and don't crash if the rename timer
fires while the window is dead but still referenced. Fixes problem
reported by Michael Scholz.
Instead of numbering choose mode items 0-9a-z and then nothing, number
them all and if there are more than 10 use a prompt when 0-9 is
pressed. From Thomas Adam.
Add a simple form of output rate limiting by counting the number of
certain C0 sequences (linefeeds, backspaces, carriage returns) and if it
exceeds a threshold (current default 50/millisecond), start to redraw
the pane every 100 milliseconds instead of making each change as it
comes. Two configuration options - c0-change-trigger and
c0-change-interval.
This makes tmux much more responsive under very fast output (for example
yes(1) or accidentally cat'ing a large file) but may not be perfect on
all terminals and connections - feedback very welcome, particularly
where this change has a negative rather than positive effect (making it
off by default is a possibility).
After much experimentation based originally on a request Robin Lee
Powell (which ended with a completely different solution), this idea
from discussion with Ailin Nemui.
