Don't call tty_free unless the client is a terminal, otherwise tty_init hasn't
been called and it may end up doing close(0). From Kalle Olavi Niemitalo.
Add a choose-client command and extend choose-{session,window} to accept a
template. After a choice is made, %% (or %1) in the template is replaced by the
name of the session, window or client suitable for -t and the result executed
as a command. So, for example, "choose-window "killw -t '%%'"" will kill the
selected window.
The defaults if no template is given are (as now) select-window for
choose-window, switch-client for choose-session, and detach-client for
choose-client (now bound to D).
Add some other obvious variables to update-environment (WINDOWID SSH_ASKPASS
SSH_AUTH_SOCK SSH_AGENT_PID SSH_CONNECTION) so they are updated in the session
environment on new/attach.
When using source-file, run the commands in the context of the source-file
command rather than with no context. This makes things like attach work from a
file.
When moving up or down in copy mode, save the cursor position and size of the
last line with content (width != 0) and use it to determine if the cursor
should be at the end of the line. Fixes problem of the cursor always jumping to
the end of the line when scrolling past a blank line.
A few trivial optimisations: no need to check for zero size if calling
buffer_ensure in buffer.c; expand grid lines by a greater increase than one
each time; and don't read UTF-8 data unless it actually needs to be checked
when overwriting a cell.
Extend command-prompt with a -p option which is a comma-separated list of one
or more prompts to present in order.
The responses to the prompt are replaced in the template string: %% are
replaced in order, so the first prompt replaces the first %%, the second
replaces the second, and so on. In addition, %1 up to %9 are replaced with the
responses to the first the ninth prompts
The default template is "%1" so the response to the first prompt is processed
as a command.
Note that this changes the behaviour for %% so if there is only one prompt,
only the first %% will be replaced. Templates such as "neww -n '%%' 'ssh %%'"
should be changed to "neww -n '%1' 'ssh %1'".
From Tiago Cunha.
Instead of just checking for an empty buffer, which may not be the case if
there is unconsumed data, save the previous size and use it instead. This means
that activity monitoring should work in this (unlikely) event.
Also remove a debugging statement that no longer seems necessary.
options_get_number() is relatively expensive and a check for dead panes happens
a lot more often than actually finding one, so instead of getting the option
for every check, get it for every dead window found.
Now that pane targets (-t) are supported, switch some commands to use them
where it makes sense: clock-mode, copy-mode, scroll-mode, send-keys,
send-prefix.
