and not have to wait for an update when they change pane, we allow
commands to run more than once a second if the expanded form
changes. Unfortunately this can mean them being run far too often
(pretty much continually) when multiple clients exist, because some
formats (including #D) will always differ between clients.
To avoid this, give each client its own tree of jobs which means that
the same command will be different instances for each client - similar
to how we have the tag to separate commands for different panes.

jobs, this means that if the same job is used for different windows or
panes (for example in pane-border-format), it will be run separately for
each pane.
The vi-copy and emacs-copy mode key tables are gone, and instead copy
mode commands are bound in one of two normal key tables ("copy-mode" or
"copy-mode-vi"). Keys are bound to "send-keys -X copy-mode-command". So:
bind -temacs-copy C-Up scroll-up
bind -temacs-copy -R5 WheelUpPane scroll-up
Becomes:
bind -Tcopy-mode C-Up send -X scroll-up
bind -Tcopy-mode WheelUpPane send -N5 -X scroll-up
This allows the full command parser and command set to be used - for
example, we can use the normal command prompt for searching, jumping,
and so on instead of a custom one:
bind -Tcopy-mode C-r command-prompt -p'search up' "send -X search-backward '%%'"
command-prompt also gets a -1 option to only require on key press, which
is needed for jumping.
The plan is to get rid of mode keys entirely, so more to come eventually.
uint64_t and converting UTF-8 to Unicode on input and the reverse on
output. (This allows key bindings, there are still omissions - the
largest being that the various prompts do not accept UTF-8.)
keys. The default key bindings become the "prefix" table and -n the
"root" table. Keys may be bound in new tables with bind -T and
switch-client -T used to specify the table in which the next key should
be looked up. Based on a diff from Keith Amling.
directly with a helper function in the cmd_entry, include a table of
bind-key commands and pass them through the command parser and a
temporary cmd_q.
As well as being smaller, this will allow default bindings to be command
sequences which will probably be needed soon.
commands and allow a command to block execution of subsequent
commands. This allows run-shell and if-shell to be synchronous which has
been much requested.
Each client has a default command queue and commands are consumed one at
a time from it. A command may suspend execution from the queue by
returning CMD_RETURN_WAIT and then resume it by calling cmd_continue() -
for example run-shell does this from the callback that is fired after
the job is freed.
When the command queue becomes empty, command clients are automatically
exited (unless attaching). A callback is also fired - this is used for
nested commands in, for example, if-shell which can block execution of
the client's cmdq until a new cmdq becomes empty.
Also merge all the old error/info/print functions together and lose the
old curclient/cmdclient distinction - a cmdq is bound to one client (or
none if in the configuration file), this is a command client if
c->session is NULL otherwise an attached client.
add a new value to mean "leave client running but don't attach" to fix
problems with using some commands in a command sequence. Most of the
work by Thomas Adam, problem reported by "jspenguin" on SF bug 3535531.
Originally, tmux commands were parsed in the client process into a
struct with the command data which was then serialised and sent to the
server to be executed. The parsing was later moved into the server (an
argv was sent from the client), but the parse step and intermediate
struct was kept.
This change removes that struct and the separate parse step. Argument
parsing and printing is now common to all commands (in arguments.c) with
each command left with just an optional check function (to validate the
arguments at parse time), the exec function and a function to set up any
key bindings (renamed from the old init function).
This is overall more simple and consistent.
There should be no changes to any commands behaviour or syntax although
as this touches every command please watch for any unexpected changes.
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).
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.
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.
