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.
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.
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.
- 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.
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.
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).
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@.
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.
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).
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.
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.
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.
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.
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.
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.
From Tiago Cunha, thanks!
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.
annoying and it is only use for iterating, so use a sentinel to mark the end of
each array instead. Different fix for a problem pointed out by Kalle Olavi
Niemitalo.
