Add a TTY_OPENED flag and tidy a little.
|
| |
|
|
|
|
| |
Drop the no_stop argument to tty_close and tty_free in favour of a flag in the
tty struct.

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.

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.

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 session 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.

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.

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 contains 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.

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.

Using the alternative screen (smcup/rmcup) should also preserve the current
colours and attributes. Found thanks to a report from Taylor Venable.
While here also nuke a couple of extra blank lines.

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

Rename struct hdrtype to msgtype which is a better name and can be used even
when struct hdr disappears.

Final pieces of mode key rebinding: bind-key and unbind-key now accept a -t
argument to modify a table.
|
| |
|
|
|
|
|
|
| |
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).
|
| |
|
|
|
|
| |
If select-layout is not given an argument, reapply the last layout used in the
window, if any.

Remove an unused entry in the mode keys command enum and rename
MODEKEYCOPY_QUIT to _CANCEL to match the others.
|
| |
|
|
|
|
|
|
|
| |
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.
|
| |
|
|
|
| |
Get rid of empty mode_key_free function.

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.

Tidy client message return slightly: convert flags into an enum, and merge
error string into struct client_ctx as well.

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.

window_add_pane cannot fail, so remove the unused cause argument and don't
bother to check for a NULL return.

tty_write is relatively short and the only function left in tty-write.c so
move it into tty.c.
|
| |
|
|
|
|
| |
More tty code tidying: move the saved cursor/region position (from before the
screen was updated) out of struct screen and into struct tty_ctx.
|
| |
|
|
|
|
|
| |
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.
|
| |
|
|
|
|
| |
There are relatively few arguments to tty_cmd_* functions now, so tidy them up
by using a struct rather than hiding everything with varargs.
|
| |
|
|
|
|
| |
tty_cmd_raw is only used once, for raw UTF-8 output, so rename it to
tty_cmd_utf8character and eliminate the size argument.
|
| |
|
|
|
|
| |
Make some functions which return unused values void (mostly found by lint) and
tweak a redundant expression in window_pane_set_mode.
|

Remove a couple of unused functions and fix a type ("FALLTHOUGH"), found by
lint.

__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.
|

Tidy up keys: use an enum for the key codes, and remove the macros which just
wrap flag sets/clears/tests.

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.
