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).
socketpair and setting it to -1 to mark when the other side is
closed. This avoids closing it while the libevent bufferevent still has
it (it could try to add it to the polled set which some mechanisms don't
like). Fixes part a problem reported by Bruno Sutic.
use event_once to queue a callback to deal with them. Also dead clients
with references would never actually be freed because the wrap-up
functions (the callback for stdin, or status_prompt_clear) would never
be called. So call them in server_client_lost.
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.
consistent but with much less duplication, but keeping the same internal
API. Also adds more readable aliases for some of the special tokens used
in targets (eg "{start}" instead of "^"). Some behaviours may have
changed, for example prefix matches now happen before fnmatch.
keys. The default key bindings become the "prefix" table and -n the
"root" table. Keys may be bound in new tables with bind -T and
switch-client -T used to specify the table in which the next key should
be looked up. Based on a diff from Keith Amling.
