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).
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@.
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.
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 mode key bindings (new
-t argument).
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.
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.
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.
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.
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.
enum tty_cmd is only used as an index into the array of command function
pointers, so remove it and use the function pointers directly to represent
themselves.
__progname is not const, pointed out by deraadt.
And, as a consequence change its declaration for operating systems which
don't provide __progname as well.
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.
If these are enabled (and the monitor-activity, bell-action 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" by default).
- Add support for including the window index, pane index, and window name
in status-left, or status-right.
- Bump protocol version.
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.
decision for whether or not a pane should be drawn out of the layout code and
into the redraw code.
This is needed for the new layout design, getting it in now to make that easier
to work on.
maintain and is only going to get worse as more are used. So instead, add a new
uint64_t member to cmd_entry which is a bitmask of upper and lowercase options
accepted by the command.
This means new single character options can be used without the need to add it
explicitly to the list.
- move the code back into cmd.c and merge with the existing functions where
possible;
- accept "-tttyp0" as well as "-t/dev/ttyp0" for clients;
- when looking up session names, try an exact match first, and if that fails
look for it as an fnmatch pattern and then as the start of a name - if more
that one session matches an error is given; so if there is one session called
"mysession", -tmysession, -tmysess, -tmysess* are equivalent but if there
is also "mysession2", the last two are errors;
- similarly for windows, if the argument is not a valid index or exact window
name match, try it against the window names as an fnmatch pattern and a
prefix.
screen interactive programs to preserve the screen contents. When activated, it
saves a copy of the visible grid and disables scrolling into and resizing out
of the history; when deactivated the visible data is restored and the history
reenabled.
and makes emacs happy when pasting into some modes. A new -r (raw) flag to
paste-buffer pastes without the translation.
From Kalle Olavi Niemitalo, thanks!
argument if the shell command in the first succeeds, for example:
if "[ -e ~/.tmux.conf.alt ]" "source .tmux.conf.alt"
Written by Tiago Cunha, many thanks.
normal eight-bit output is wrong, separate it into a different function. Fixes
spacing when mixing UTF-8 with some escape sequences, notably the way w3m does
it.
status-left/status-right work properly. At the moment any top-bit-set
characters are assumed to be UTF-8: a status-utf8 option to configure this will
come shortly.
highlight the status line if it matches.
- To make this possible, the function cmd_find_window_search from
cmd-find-window.c had to be moved to window.c and renamed window_pane_search.
- While there use three new functions in server.c to check for bell, activity,
and content, to avoid too much nesting.
- change the one layout function into two _refresh and _resize
- create layout-manual.c for manual layout code
- move the fit panes/update panes code from window.c to the new file as it is only used by manual layout now
- move the resize pane code into layout-manual.c as well
- get rid of the direct calls to fit/update and make them go through layout
- rename a couple of variables
This is mainly as a first step before reworking the manual layout code to see if anything breaks.
script which must be run before building.
Still two makefiles but they are a hell of a lot simpler.
HAVE_* also will make it easier to move to $buildsystem if necessary later.
redraw the entire window. Also add a flag to skip updating the window any
further if it is scheduled to be redrawn. This has the effect of batching
multiple redraws together.
issues - particularly, don't mix with manual pane resizing and be careful when
viewing from multiple clients; generally cycling the layout a few times will
fix most problems. Getting this in for testing while I think about how to deal
with manual mode.
Split window as normal and cycle the layouts with C-b space. Some of the
layouts will work better when swap-pane comes along.
as UTF-8 in a separate array, the code does a lookup into this every time it
gets to a UTF-8 cell. Zero width characters are just appended onto the UTF-8
data for the previous cell. This also means that almost no bytes extra are
wasted non-Unicode data (yay).
Still some oddities, such as copy mode skips over wide characters in a strange
way, and the code could do with some tidying.
Split grid into two arrays, one containing grid attributes/flags/colours (keeps
the name grid_cell for now) and a separate with the character data (called
text). The text is stored as a u_short but is treated as a uint64_t elsewhere;
eventually the grid will have two arrays.
I'm not happy with the naming so that might change.
Still need to decide where to go from here. I'm not sure whether to combine
the peek/set functions together, and also whether to continue to treat the
text as a uint64_t (and convert to/from Unicode) or make it a char array
(of size one when UTF-8 disabled, eight when enabled) and keep everything
as UTF-8.
Also since UTF-8 will eventually become an attribute of the grid itself it
might be nice to move all the padding crap into grid.c.
tmux-1000. The default socket is thus /tmp/tmux-UID/default. To start a
separate server, the new -L command line option should be used: this creates a
socket in the same directory with a different name ("-L main" will create
socket called "main"). -S should only be used to place the socket outside
/tmp. This makes sockets a little more secure and a bit more convenient to use
multiple servers.
which may involve changing the cursor position; however, the old (before
redraw) cursor position is necessary for writing to the tty. So, save it before
doing the redraw then update the internal screen then update the tty.
Not sure I like this solution but it does the job for now.
by reading argv[0] from the process group leader of the group that owns the tty
(tcgetpgrp()). This can't be done portably so some OS-dependent code is
introduced (ugh); OpenBSD, FreeBSD and Linux are supported at the moment.
A new window flag, automatic-rename, is available: if this is set to off, the
window name is not changed. Specifying a name with the new-window, new-session
or rename-window commands will automatically set this flag to off for the
window in question. To disable it entirely set the option to off globally (setw
-g automatic-rename off).
