been a limitation for a long time.
There are 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. The default is
currently largest but this may change. 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). The
offset of the visible portion of the window is shown in status-right.
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-window
-x or -y, and "setw -u window-size" to revert to automatic sizing..
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 much higher memory use if making a window excessively
big. The minimum size is the size required for the current layout
including borders.
The refresh-client command can be used to pan around a window, -U -D -L
-R moves up, down, left or right and -c returns to automatic cursor
tracking. The position is reset when the current window is changed.

some modern features.
Now the common code is in mode-tree.c, which provides an API used by the
three modes now separated into window-{buffer,client,tree}.c. Buffer
mode shows buffers, client mode clients and tree mode a tree of
sessions, windows and panes.
Each mode has a common set of key bindings plus a few that are specific
to the mode. Other changes are:
- each mode has a preview pane: for buffers this is the buffer content
(very useful), for others it is a preview of the pane;
- items may be sorted in different ways ('O' key);
- multiple items may be tagged and an operation applied to all of them
(for example, to delete multiple buffers at once);
- in tree mode a command may be run on the selected item (session,
window, pane) or on tagged items (key ':');
- displayed items may be filtered in tree mode by using a format (this
is used to implement find-window) (key 'f');
- the custom format (-F) for the display is no longer available;
- shortcut keys change from 0-9, a-z, A-Z which was always a bit weird
with keys used for other uses to 0-9, M-a to M-z.
Now that the code is simpler, other improvements will come later.
Primary key bindings for each mode are documented under the commands in
the man page (choose-buffer, choose-client, choose-tree).

command. This is used for the session, window and pane for all commands
in the command sequence if there is no -t or -s.
However, using it for all commands in the command sequence means that if
the active pane or current session is changed, subsequent commands still
use the previous state. So make commands which explicitly change the
current state (such as neww and selectp) update it themselves for later
commands. Commands which may invalidate the state (like killp) are
already OK because an invalid state will be ignored.
Also fill in the current state for all key bindings rather than just the
mouse, so that any omissions are easier to spot.

but there is also now a global command queue. Instead of command queues
being dispatched on demand from wherever the command happens to be
added, they are now all dispatched from the top level server
loop. Command queues may now also include callbacks as well as commands,
and items may be inserted after the current command as well as at the end.
This all makes command queues significantly more predictable and easier
to use, and avoids the complex multiple nested command queues used by
source-file, if-shell and friends.
A mass rename of struct cmdq to a better name (cmdq_item probably) is
coming.

confusing, particularly trying to automatically figure out what target
hooks should be using. So simplify it:
- drop before hooks entirely, they don't seem to be very useful;
- commands with special requirements now fire their own after hook (for
example, if they change session or window, or if they have -t and -s
and need to choose which one the hook uses as current target);
- commands with no special requirements can have the CMD_AFTERHOOK flag
added and they will use the -t state.
At the moment new-session, new-window, split-window fire their own hook,
and display-message uses the flag. The remaining commands still need to
be looked at.
|
|
- Prepare the state again before the "after" hooks are run, because the
command may have killed or moved windows.
- Use the hooks list from the newly prepared target, not the old hooks
list (only matters for new-session really).
- Correctly detect an invalid current state and ignore it in
cmd_find_target ("killw; swapw").
- Change neww, new, killp, killw, splitw, swapp, swapw to update the
current state (used if no explicit target is given) to something more
useful after they have finished. For example, neww changes it to the
newly created window.
Hooks are still relatively new and primitive so there are likely to be
more changes to come.

the state (client, session, winlink, pane) for it it before entering the
command. Each command provides some flags that tell the prepare step
what it is expecting.
This is a requirement for having hooks on commands (for example, if you
hook "select-window -t1:2", the hook command should to operate on window
1:2 not whatever it thinks is the current window), and should allow some
other target improvements.
The old cmd_find_* functions remain for the moment but that layer will
be dropped later.

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).
