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.
Add (naive) searching and goto line in copy mode. Searching is C-r and C-s with
emacs keys, / and ? with vi; n repeats the search again with either key
set. All searching wraps the top/bottom. Goto line is g for both emacs and vi.
The search prompts don't have full line editing, just simple append and delete
characters.
Also sort the mode keys list in tmux.1.
sys/ttydefaults.h is just a copy of the file from *BSD, taking no account of
the fact that their OWN termios.h uses entirely different indexes into the
array.
I know ttydefaults.h is not meant to be portable, but you'd think it would be
obvious to anyone that no file is better than a broken one...
Send SGR0 when initialising the screen. Fixes problems on terminals with BCE
(like putty) if the background colours is non-default when tmux starts. May
also fix problems when resuming a suspended tmux.
Switch the prompt code to return an empty string when the user enters no
response and reserve NULL for an explicit cancel. Change all callbacks to treat
them the same so no functional change.
Also add cancel key bindings to emacs mode which were missing.
vi(1)-style half page scroll in copy and scroll modes. Move the vi full page
scroll key to C-b instead of C-u and use C-u/C-d for half page scrolling with
vi keys. In emacs mode, half page scrolling is bound to M-Up and M-Down.
Suggested by merdely (about a year ago :-)).
Scroll by two less than the number of lines in the screen, like emacs, rather
than by the entire screen, to make it easier to pull things out from under the
line indicator. Suggested by claudio.
Allowing copy mode to scroll left and right is annoying, so limit it to the
real screen width. To indicate the cursor is at the end of the line rather than
the cell before, put a '$' in the last cell.
Also clear the selection when the terminal is resized to avoid tmux getting
confused.
Rather than telling the client to exit in the function when creating a new
session detached, let the caller do it. Allows "tmux new -d \; attach" to work.
When creating a new session from the command-line where there is an external
terminal, copy the termios(4) special characters and use them for new windows
created in the new session. Suggested by Theo.
It was originally intended that scroll mode would show content that was
currently off-screen due to resize, but somewhere along the way this got
lost. Restore this behaviour to scroll mode by fixing screen_write_copy to read
up to the saved line length rather than the current screen width. Copy mode
remains unaltered for now.
If the client passes zero for the window size in the identify message (which it
can, for example on serial terminals), reset it to 80x25, same as for resize
messages. Problem reported by kettenis@.
A tty context must not be modified as it may be reused to update multiple
clients, so make it const.
Also fix an actual modification which caused a hang when a session was
connected to multiple terminals at least one of which was missing ich/ich1.
imsg closes the fd after sending, so dup() STDIN_FILENO before passing it to
the parent, otherwise TIOCGWINSZ will fail when the window is resized (that
could actually be moved into the server but this is more future-proof and
avoids breaking the protocol).
Initialise log_fd to -1, prevents spurious disconnection of the client when it
ends up as fd 0 (likely if the server is started with "tmux start").
Also add some extra debugging messages to server.c.
