is larger than the client manually. Bound to S-Up, S-Down, S-Left,
S-Right and Delete manually.
Also add aliases for keys DC = Delete, IC = Insert, and make
refresh-client -C accept XxY as well as X,Y to match default-size.
This adds two new options, window-size and default-size, and a new
command, resize-window.
The force-width and force-height options, and the session_width and
session_height formats have been removed.
The new window-size option tells tmux how to work out the size of
windows: largest means it picks the size of the largest session,
smallest the smallest session (similar to the old behaviour) and
manual means that it does not automatically resize
windows. aggressive-resize modifies the choice of session for largest
and smallest as it did before.
If a window is in a session attached to a client that is too small,
only part of the window is shown. tmux attempts to keep the cursor
visible, so the part of the window displayed is changed as the cursor
moves (with a small delay, to try and avoid excess redrawing when
applications redraw status lines or similar that are not currently
visible).
Drawing windows which are larger than the client is not as efficient
as those which fit, particularly when the cursor moves, so it is
recommended to avoid using this on slow machines or networks (set
window-size to smallest or manual).
The resize-window command can be used to resize a window manually. If
it is used, the window-size option is automatically set to manual for
the window (undo this with "setw -u window-size"). resize-window works
in a similar way to resize-pane (-U -D -L -R -x -y flags) but also has
-a and -A flags. -a sets the window to the size of the smallest client
(what it would be if window-size was smallest) and -A the largest.
For the same behaviour as force-width or force-height, use
resize-width -x or -y.
If the global window-size option is set to manual, the default-size
option is used for new windows. If -x or -y is used with new-session,
that sets the default-size option for the new session.
The maximum size of a window is 10000x10000. But expect applications
to complain and higher memory use if you make a window that big. The
minimum size is the size required for the current layout including
borders.
This change allows some code improvements, most notably that since
windows can now never be cropped, that code can be removed from the
layout code, and since panes can now never be outside the size of the
window, window_pane_visible can be removed.
intended as the target client where the message should be displayed but
at some point (perhaps when -p was added), it was used for format
expansion too. This means it can get a bit weird where you have client
formats expanding for a client with a different current session than the
target session.
However, it is nice that display-message can be used to show information
about a specific client. So change so that the -c client will be used if
the session matches the target session (-t or default), otherwise the
best client will be chosen.
automatically zoom the pane when the mode is entered and unzoom when it
exits, assuming the pane is not already zoomed. Add -Z to the default
key bindings.
performance cost with a large history. Instead change back to using a
second grid and copying modified lines over which is much faster (this
doesn't revert to the old code however which didn't support UTF-8
properly). GitHub issue 1249.
colour ("true" or "direct" colour). These consist of new entries (such
as "xterm-direct") which have a different setaf/setab implementation,
colors and pairs set to 0x1000000 and 0x10000, and a new RGB flag.
The setaf/setab definitions seem to be geared towards what ncurses (or
emacs maybe) needs, in that the new versions do only ANSI and RGB
colours (they can't be used for the 256 colour palette); they rely on
the silly ISO colon-separated version of SGR; and they use a weird
multiplication scheme so they still only need one argument. The higher
values of colors and pairs require a recent ncurses to parse.
tmux can use the RGB flag to detect RGB colour support (keeping the old
Tc extension for backwards compatibility for now). However, as we still
want to send 256 colour information unchanged when possible, the new
setaf/setab are awkward. So when RGB is present, reserve setaf/setab
only for ANSI colours and use the escape sequences directly for 256 and
RGB colours. (To my knowledge no recent terminal uses unusual escape
sequences for these in any case.)
background is default (8), introduce an explicit free function and use
it where a free alone is needed. Likewise, use memmove directly rather
than grid_move_lines where it makes sense. Based on a memory leak fix by
Dan Aloni in GitHub issue 1051.
