3ad4de6c8c Add a base-index session option to specify the first index checked when looking
for an index for a new window.

52793e7a3f 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.

bc497dbb92 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.

4310282a4c Have the client pass its stdin fd to the server when identifying itself and
have the server use that rather than reopening the tty. If the fd isn't given,
use the old behaviour (so no need for a version change).

This allows tmux to be used as the shell, so also change so that when working
out the command to execute if default-command is empty (the default), tmux will
try not execute itself.

f0635717b3 Switch tmux to use imsg. This is the last major change to make the
client-server protocol more resilient and make the protocol versioning work
properly. In future, the only things requiring a protocol version bump will be
changes in the message structs, and (when both client and server have this
change) mixing different versions should nicely report an error message.

As a side effect this also makes the code tidier, fixes a problem with the way
errors reported during server startup were handled, and supports fd passing
(which will be used in future).

Looked over by eric@, thanks.

Please note that mixing a client with this change with an older server or vice
versa may cause tmux to crash or hang - tmux should be completely exited before
upgrading.

60db6e3df4 Add flags for 1+2 and 2 arguments to the generic target code, use it for
cmd-set-environment/option/window-option and remove the generic options
parsing.

6491274f60 Infrastructure and commands to manage the environment for processes started
within tmux.

There is a global environment, copied from the external environment when the
server is started and each sesssion has an (initially empty) session
environment which overrides it.

New commands set-environment and show-environment manipulate or display the
environments.

A new session option, update-environment, is a space-separated list of
variables which are updated from the external environment into the session
environment every time a new session is created - the default is DISPLAY.

06ddd3dcf8 Add a flags member to the grid_line struct and use it to differentiate lines
wrapped at the screen edge from those terminated by a newline. Then use this
when copying to combine wrapped lines together into one.

5e01b6d663 Change the way the grid is stored, previously it was:
- a two-dimensional array of cells;
- a two-dimensional array of utf8 data;
- an array of line lengths.

Now it is a single array of a new struct grid_line each of which represents a
line and containts the length and an array of cells and an array of utf8 data.

This will make it easier to add additional per-line members, such as flags.

e89e70e715 If there is an error in the configuration file, don't just exit(1) as this can
cause the client to hang. Instead, send the error message, then mark the client
as bad and start a normal shutdown so the server exits once the error is
written.

This also allows some code duplicating daemon(3) to be trimmed and logging to
begin earlier.

Prompted by Theo noticing the behaviour on error wasn't documented.

04e97e8aef Using the alternative screen (smcup/rmcup) should also preserve the current
colours and attributes. Found thanks to a report from Taylor Venable.

12ef3ceda1 Add a -a flag to set-option and set-window-option to append to an existing
string value, useful for terminal-overrides.

Nicholas Marriott
1673735f02 Add a terminal-overrides session option allowing individual terminfo(5) entries
to be overridden. The 88col/256col checks are now moved into the default
setting and out of the code.

Also remove a couple of old workarounds for xterm and rxvt which are no longer
necessary (tmux can emulate them if missing).

5f13bb0c3a There aren't many client message types or code to handle them so get rid of the
lookup table and use a switch, merge the tiny handler functions into it, and
move the whole lot to client.c.

Also change client_msg_dispatch to consume as many messages as possible and
move the call to it to the right place so it checks for signals afterwards.

Prompted by suggestions from eric@.

071494d8fa Merge pane number into the target specification for pane commands. Instead of
using -p index, a target pane is now addressed with the normal -t window form
but suffixed with a period and a pane index, for example :0.2 or
mysess:mywin.1. An unadorned number such as -t 1 is tried as a pane index in
the current window, if that fails the same rules are followed as for a target
window and the current pane in that window used.

As a side-effect this now means that swap-pane can swap panes between different
windows.

Note that this changes the syntax of the break-pane, clear-history, kill-pane,
resize-pane, select-pane and swap-pane commands.

86785004ba Next step towards customisable mode keys: build each default table of keys into
a named tree on start and use that for lookups. Also add command to string
translation tables and modify list-keys to show the the mode key bindings (new
-t argument).

d95274c5f2 Change mode key bindings from big switches into a set of tables. Rather than
lumping them all together, split editing keys from those used in choice/more
mode and those for copy/scroll mode.

Tidier and clearer, and the first step towards customisable mode keys.

639fbe0392 Detect backspace by looking at termios VERASE and translate it into \177 (which
matches screen's behaviour if not its termcap/terminfo entry). The terminfo kbs
cap is often wrong or missing so it can't be used, and just assuming \177 may
be wrong.

34a82e7629 Make all messages sent between the client and server fixed size.
This is the first of two changes to make the protocol more resilient and less
sensitive to other changes in the code, particularly with commands. The client
now packs argv into a buffer and sends it to the server for parsing, rather
than doing it itself and sending the parsed command data.

As a side-effect this also removes a lot of now-unused command marshalling
code.

Mixing a server without this change and a client with or vice versa will cause
tmux to hang or crash, please ensure that tmux is entirely killed before
upgrading.

5a1a106637 Permit commands to be bound to key presses without the prefix key first. The
new -n flag to bind-key and unbind-key sets or removes these bindings, and
list-key shows them in []s.

96a7cf1e6a Both of cmdclient and curclient CAN be NULL - if the command is executed from
the configuration file. In this case, attach-session can't do much, and
new-session should just assume -d.

6036bdd06c Improved layout code.
Each window now has a tree of layout cells associated with it. In this tree,
each node is either a horizontal or vertical cell containing a list of other
cells running from left-to-right or top-to-bottom, or a leaf cell which is
associated with a pane.

The major functional changes are:

- panes may now be split arbitrarily both horizontally (splitw -h, C-b %) and
  vertically (splitw -v, C-b ");
- panes may be resized both horizontally and vertically (resizep -L/-R/-U/-D,
  bound to C-b left/right/up/down and C-b M-left/right/up/down);
- layouts are now applied and then may be modified by resizing or splitting
  panes, rather than being fixed and reapplied when the window is resized or
  panes are added;
- manual-vertical layout is no longer necessary, and active-only layout is gone
  (but may return in future);
- the main-pane layouts now reduce the size of the main pane to fit all panes
  if possible.

Thanks to all who tested.

fc6a65c620 Add three new session options: visual-activity, visual-bell, visual-content. If
these are enabled (and the monitor-activity, bell-actio and monitor-content
options are configurated appropriately), when activity, a bell, or content is
detected, a message is shown.

Also tidy up the bell/activity/content code in server.c slightly and fix a
couple of errors.

6f5150a943 - New command display-message (alias display) to display a message in the
status line (bound to "i" and displays the current window and time by
  default). The same substitutions are applied as for status-left/right.
- Add support for including the window index (#I), pane index (#P) and window
  name (#W) in the message, and status-left or status-right.
- Bump protocol version.

65deba3a35 Memory could be leaked if a second prompt or message appeared while another was
still present, so add a separate prompt free callback and make the _clear
function responsible for calling it if necessary (rather than the individual
prompt callbacks). Also make both messages and prompts clear any existing when
a new is set.

In addition, the screen could be modified while the prompt is there, restore
the redraw-entire-screen behaviour on prompt clear; add a comment as a
reminder.
