2016-02-12Expand client formats in run-shell.nicm
2015-12-14Instead of combined flags for -c, -s, -t, split into different setsnicm
using an enum and simplify the parsing code.
2015-12-13Use member names in cmd_entry definitions so I stop getting confusednicm
about the order.
2015-12-13Instead of every command resolving the target (-t or -s) itself, preparenicm
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 thenicm
command name (will also be used for more later).
2015-12-08Remove format_create_flags and just pass flags to format_create.nicm
2015-10-31Because pledge(2) does not allow us to pass directory file descriptorsnicm
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).nicm
2015-04-24Set working directory for run-shell and if-shell.nicm
2015-02-05Wrap all the individual format_* calls in a single format_defaultsnicm
functions.
2014-10-20Instead of setting up the default keys by building the key structnicm
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.
2014-04-17Remove the "info" message mechanism, this was only used for about fivenicm
mostly useless and annoying messages. Change those commands to silence on success like all the others. Still accept the -q command line flag and "quiet" server option for now.

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.
2013-03-24Add 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.
2013-03-22evbuffer_readline returns allocated storage, don't leak it.Nicholas Marriott
2013-03-22Add functions to allocate and free command contexts rather than doing itNicholas Marriott
all on the stack.
2012-11-27Allow cmd-run-shell to accept -t to specify the pane to display theNicholas Marriott
output, requested by Alexander Tsepkov.
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
2011-01-26Simplify 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.
2010-05-25Don't die if the client has been detached when the job finishes, justNicholas Marriott
don't display the output.
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.
2009-11-04Switch jobs over to use a bufferevent.Nicholas Marriott
2009-11-01Add a flag for jobs that shouldn't be freed after they've died and use it forNicholas Marriott
status jobs, then only kill those jobs when status-left, status-right or set-titles-string is changed. Fixes problems with changing options from inside #().
