of storing a full grid_cell with UTF-8 data and everything, store a new
type grid_cell_entry. This can either be the cell itself (for ASCII
cells), or an offset into an extended array (per line) for UTF-8
data.
This avoid a large (8 byte) overhead on non-UTF-8 cells (by far the
majority for most users) without the complexity of the shadow array we
had before. Grid memory without any UTF-8 is about half.
The disadvantage that cells can no longer be modified in place and need
to be copied out of the grid and back but it turned out to be lot less
complicated than I expected.
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).
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.
1. In vi mode the selection doesn't include the last character if you
moved the cursor up or left.
2. In emacs mode the selection includes the last character if you moved
the cursor to the left.

much as before - buffers are automatically named "buffer0000",
"buffer0001" and so on and ordered as a stack. Buffers can be named
explicitly when creating ("loadb -b foo" etc) or renamed ("setb -b
buffer0000 -n foo"). If buffers are named explicitly, they are not
deleted when buffer-limit is reached. Diff from J Raynor.
store it in struct mouse_event, reduce the scroll size the 3 but allow
shift to reduce it to 1 and meta and ctrl to multiply by 3 if the
terminal supports them, also support wheel in choose mode. From Marcel
Partap.
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.
