it for panes with some degree of fairness. GitHub issue 2217, with

pane stored in the window. This is can be used with session groups which
allow an independent current window (although it would be nice to have a
flag for this too and remove session groups). The client active pane is
only really useful interactively, many things (hooks, window-style,
zooming) still use the window active pane.

ignore-size) flag - both behaviours are useful in different
circumstances.

which allows formats to be expanded. Any styles without a '#{' are still
validated when they are set but any with a '#{' are not. Formats are not
expanded usefully in many cases yet, that will be changed later.
To make this work, a few other changes:
- set-option -a with a style option automatically appends a ",".
- OSC 10 and 11 don't set the window-style option anymore, instead the
fg and bg are stored in the pane struct and act as the defaults that
can be overridden by window-style.
- status-fg and -bg now override status-style instead of trying to keep
them in sync.

Lots of scope for being more sophisticated left here.

added and using that as a marker for xterm(1)-like, assume that if the
terminfo(5) entry already has XT or the clear capability starts with CSI then
the terminal is VT100-like and it should be safe to send DA requests. The DA
responses trigger additional features being added.
This is all to detect extensions if terminfo(5) is wrong or inadequate. If it
fails, tmux will just fall back to using the capabilities in the terminfo(5)
entry alone.
terminal features, each of which are defined in one place and map to a
builtin set of terminfo(5) capabilities. Features can be specified based
on TERM with a new terminal-features option or with the -T flag when
running tmux. tmux will also detect a few common terminals from the DA
and DSR responses.
This is intended to make it easier to configure tmux's use of
terminfo(5) even in the presence of outdated ncurses(3) or terminfo(5)
databases or for features which do not yet have a terminfo(5) entry.
Instead of having to grok terminfo(5) capability names and what they
should be set to in the terminal-overrides option, the user can
hopefully just give tmux a feature name and let it do the right thing.
The terminal-overrides option remains both for backwards compatibility
and to allow tweaks of individual capabilities.
tmux already did much of this already, this makes it tidier and simpler
to configure.
clear it on the first redraw, and it can't be set when we are finished
or they would be redrawn again, so if the redraw is deferred for a
client, copy the redraw flag into a separate set of bits just for that
client.
the data from the last one, other panes could update while waiting, so
we set the flag to redraw them all when the new redraw actually
happened. But this means a lot of redrawing panes unnecessarily if they
haven't changed - so instead set a flag to say "at least one pane needs
to be redrawed" then look at the invidual pane flags to see which ones
need it.

newlines. This means that for example bind q { a \n b } and bind q "a ;
b" are the same. Also log commands in different groups separated by ;;
rather than ; (a command list like this should never be user visible).
creating a new state for each group of commands, require the caller to
create one and use it for all the commands in the list. This means the
current target works even with list with multiple groups (which can
happen if they are defined with newlines).
reference to it, it isn't necessary that the pane in copy mode is the
same as the one copying from. Add a -s flag to copy-mode to specify a
different pane for the source content. This means it is possible to view
two places in a pane's history at the same time in different panes, or
copy from a pane's history into an editor or shell in the same pane.

This means that stray relies are not left on the terminal if the command

to receive them. Prompted by a problem report from espie@.

double click, even if the timer hasn't expired to confirm it isn't

triple clicks or can make their commands have no side effects to avoid
the double click timer delay.
umask 177 instead of 117 because it may not be in a safe directory like
the default directory in /tmp. The user can chmod it more open after it

use this to add descriptions to the default key bindings. A new -N flag
to list-keys shows key bindings with notes rather than the default
bind-key command used to create them. Change the default ? binding to
use this to show a readable summary of keys.
Also extend command-prompt to return the name of the key pressed and add
a default binding (/) to show the note for the next key pressed

The path is only used internally so there is no real need for
realpath(), remove it and move the get_path function to file.c where all
the callers are.
not attached, the server process asks it to open the file, similar to
how works for stdin, stdout, stderr. This makes special files like
/dev/fd/X work (used by some shells). stdin, stdout and stderr and
control mode are now just special cases of the same mechanism. This will
also make it easier to use for other commands that read files such as
source-file.

Change remain-on-exit and window-style/window-active-style to be pane

This makes select-pane -P and -g unnecessary so no longer document them

parser using yacc(1). This is a major change but is clearer and simpler
and allows some edge cases to be made more consistent, as well as
tidying up how aliases are handled. It will also allow some further
improvements later.
Entirely the same parser is now used for parsing the configuration file
and for string commands. This means that constructs previously only
available in .tmux.conf, such as %if, can now be used in string commands
(for example, those given to if-shell - not commands invoked from the
shell, they are still parsed by the shell itself).
The only syntax change I am aware of is that #{} outside quotes or a
comment is now considered a format and not a comment, so #{ is now a
syntax error (notably, if it is at the start of a line).
This also adds two new sections to the man page documenting the syntax
and outlining how parsing and command execution works.
Thanks to everyone who sent me test configs (they still all parse
without errors - but this doesn't mean they still work as intended!).
Thanks to Avi Halachmi for testing and man page improvements, also to
jmc@ for reviewing the man page changes.
