2017-04-25if-shell doesn't need to queue its error message into a callback, and inNicholas Marriott
fact it can't do so because the item it was working with will have been freed. Reported by Daniel Hahler.
2017-04-22Get rid of the extra layer of flags and cmd_prepare() and just store theNicholas Marriott
CMD_FIND_* flags in the cmd_entry and call it for the command. Commands with special requirements call it themselves and update the target for hooks to use.
2017-04-22Fix if-shell without a client (so in the config file). Reported by TheoNicholas Marriott
Buehler.
2017-04-21Store state shared between multiple commands in the queue in a sharedNicholas Marriott
structure.
2017-04-20If a #() command doesn't exit, use its most recent line of output (itNicholas Marriott
must be a full line). Don't let it redraw the status line more than once a second. Requested by someone about 10 years ago...
2017-03-08Add a helper function for the most common format_create/defaults/expandNicholas Marriott
pattern.
2017-02-03Add a window or pane id "tag" to each format tree and use it to separateNicholas Marriott
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.
2017-01-15It is silly for cmd_list_parse to return an integer error when it couldNicholas Marriott
just return NULL.
2016-10-16Mass rename struct cmd_q to struct cmdq_item and related.Nicholas Marriott
2016-10-16Rewrite command queue handling. Each client still has a command queue,Nicholas Marriott
but there is also now a global command queue. Instead of command queues being dispatched on demand from wherever the command happens to be added, they are now all dispatched from the top level server loop. Command queues may now also include callbacks as well as commands, and items may be inserted after the current command as well as at the end. This all makes command queues significantly more predictable and easier to use, and avoids the complex multiple nested command queues used by source-file, if-shell and friends. A mass rename of struct cmdq to a better name (cmdq_item probably) is coming.
2016-10-13Trying to do hooks generically is way too complicated and unreliable andNicholas Marriott
confusing, particularly trying to automatically figure out what target hooks should be using. So simplify it: - drop before hooks entirely, they don't seem to be very useful; - commands with special requirements now fire their own after hook (for example, if they change session or window, or if they have -t and -s and need to choose which one the hook uses as current target); - commands with no special requirements can have the CMD_AFTERHOOK flag added and they will use the -t state. At the moment new-session, new-window, split-window fire their own hook, and display-message uses the flag. The remaining commands still need to be looked at.
2016-10-10Add static in cmd-* and fix a few other nits.Nicholas Marriott
2016-10-09Pass file/line to new command for if-shell so that errors appearNicholas Marriott
sensibly.
2016-04-29Expand client formats (like run-shell), from Stephen M Coakley.Nicholas Marriott
2016-04-29Final parts of command hooks, add before- and after- hooks to each command.Nicholas Marriott
2016-03-01Remove some more unused variables, and use RB_FOREACH_SAFE inNicholas Marriott
key_bindings_unref_table.
2015-12-14Instead of combined flags for -c, -s, -t, split into different setsNicholas Marriott
using an enum and simplify the parsing code.
2015-12-13Use member names in cmd_entry definitions so I stop getting confusedNicholas Marriott
about the order.
2015-12-13Instead of every command resolving the target (-t or -s) itself, prepareNicholas Marriott
the state (client, session, winlink, pane) for it it before entering the command. Each command provides some flags that tell the prepare step what it is expecting. This is a requirement for having hooks on commands (for example, if you hook "select-window -t1:2", the hook command should to operate on window 1:2 not whatever it thinks is the current window), and should allow some other target improvements. The old cmd_find_* functions remain for the moment but that layer will be dropped later. Joint work with Thomas Adam.
2015-12-11Add cmdq as an argument to format_create and add a format for theNicholas Marriott
command name (will also be used for more later).
2015-12-08Remove format_create_flags and just pass flags to format_create.Nicholas Marriott
2015-11-20Memory leaks and an uninitialized part of utf8_data, from Patrick Palka.Nicholas Marriott
2015-10-31Because pledge(2) does not allow us to pass directory file descriptorsNicholas Marriott
around, we can't use file descriptors for the working directory because we will be unable to pass it to a privileged process to tell it where to read or write files or spawn children. So move tmux back to using strings for the current working directory. We try to check it exists with access() when it is set but ultimately fall back to ~ if it fails at time of use (or / if that fails too).
2015-09-16Rename cmd_q dead flag to a general flags bitmask (will be more flags later).Nicholas Marriott
2015-04-24Set working directory for run-shell and if-shell.Nicholas Marriott
2015-04-21The free callback could end up being fired before the done callbackNicholas Marriott
(happens on Cygwin), so use a reference count instead of a single flag. SF bug 188 reported by "iceboy".
2015-04-21Pass mouse events through to commands for if-shell.Nicholas Marriott
2015-04-19Rewrite of tmux mouse support which was a mess. Instead of havingNicholas Marriott
options for "mouse-this" and "mouse-that", mouse events may be bound as keys and there is one option "mouse" that turns on mouse support entirely (set -g mouse on). See the new MOUSE SUPPORT section of the man page for description of the key names and new flags (-t= to specify the pane or window under mouse as a target, and send-keys -M to pass through a mouse event). The default builtin bindings for the mouse are: bind -n MouseDown1Pane select-pane -t=; send-keys -M bind -n MouseDown1Status select-window -t= bind -n MouseDrag1Pane copy-mode -M bind -n MouseDrag1Border resize-pane -M To get the effect of turning mode-mouse off, do: unbind -n MouseDrag1Pane unbind -temacs-copy MouseDrag1Pane The old mouse options are now gone, set-option -q may be used to suppress warnings if mixing configuration files.
2015-02-05Wrap all the individual format_* calls in a single format_defaultsNicholas Marriott
functions.
2014-12-02Add -F to if-shell to allow it to be used to check for format or optionNicholas Marriott
values rather than executing a command.
2014-10-20Instead of setting up the default keys by building the key structNicholas Marriott
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.
2013-10-10Make cmdq->client_exit a tristate (-1 means "not set") so that ifNicholas Marriott
explicitly set it can be copied from child to parent cmdq by if-shell and source-file. This fixes using attach or new. From Chris Johnsen.
2013-10-10Remove the barely-used and unnecessary command check() function.Nicholas Marriott
2013-03-25Try to establish client for run-shell and if-shell if no -t.Nicholas Marriott
2013-03-25Extend jobs to support writing and use that for copy-pipe instead ofNicholas Marriott
popen, from Chris Johnsen.
2013-03-25Fix if-shell and run-shell if there are no sessions. Batted aroundNicholas Marriott
through several people, finished off by Chris Johnsen.
2013-03-24Add a command queue to standardize and simplify commands that call otherNicholas Marriott
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.
2013-03-24Expand format variables in the run-shell and if-shell shell commands,Nicholas Marriott
from Thiago Padilha.
2013-03-22Add functions to allocate and free command contexts rather than doing itNicholas Marriott
all on the stack.
2012-08-11Remove dead code, from Sean Estabrooks.Nicholas Marriott
2012-07-11Make command exec functions return an enum rather than -1/0/1 values andNicholas Marriott
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.
2012-07-10xfree is not particularly helpful, remove it. From Thomas Adam.Nicholas Marriott
2011-10-27Didn't really think the else behaviour through - requiring argv toNicholas Marriott
contain "else" is silly so just omit that, also some manpage tweaks. From Tiago Cunha.
2011-10-18Add an else clause for if-shell, from "arno-" on SourceForge.Nicholas Marriott
2011-05-25Nuke a redundant if statement, from Tiago Cunha.Nicholas Marriott
2011-01-26Simplify the way jobs work and drop the persist type, so all jobs areNicholas Marriott
fire-and-forget. Status jobs now managed with two trees of output (new and old), rather than storing the output in the jobs themselves. When the status line is processed any jobs which don't appear in the new tree are started and the output from the old tree displayed. When a job finishes it updates the new tree with its output and that is used for any subsequent redraws. When the status interval expires, the new tree is moved to the old so that all jobs are run again. This fixes the "#(echo %H:%M:%S)" problem which would lead to thousands of identical persistent jobs and high memory use (this can still be achieved by adding "sleep 30" but that is much less likely to happen by accident).
2011-01-04Clean up and simplify tmux command argument parsing.Nicholas Marriott
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.
2010-07-24When changing so that the client passes its stdout and stderr as well asNicholas Marriott
stdin up to the server, I forgot one essential point - the tmux server could now be both the producer and consumer. This happens when tmux is run inside tmux, as well as when piping tmux commands together. So, using stdio(3) was a bad idea - if sufficient data was written, this could block in write(2). When that happened and the server was both producer and consumer, it deadlocks. Change to use libevent bufferevents for the client stdin, stdout and stderr instead. This is trivial enough for output but requires a callback mechanism to trigger when stdin is finished. This relies on the underlying polling mechanism for libevent to work with whatever devices to which the user could redirect stdin, stdout or stderr, hence the change to use poll(2) over kqueue(2) for tmux.
2010-07-11Return the command client return code with MSG_EXIT now that MSG_ERROR andNicholas Marriott
MSG_PRINT are unused. New clients should be compatible with old tmux servers but vice versa may print an error.
2009-11-13Get rid of the ugly CMD_CHFLAG macro and use a const string (eg "dDU") in theNicholas Marriott
command entry structs and a couple of functions to check/set the flags.
