2020-07-21Fix show-buffer when run from inside tmux, GitHub issue 2314.nicm
2020-04-13Make client -c and -t handling common in cmd-queue.c and try to benicm
clearer about whether the client is the target client (must have a session) or not.
2020-04-13Also move cmdq_item and cmdq_list into cmd-queue.c (this is to make itsnicm
use more clearly defined and preparation for some future work).
2020-04-13Make struct cmd local to cmd.c and move it out of tmux.h.nicm
2019-12-12Rewrite the code for reading and writing files. Now, if the client isnicm
not attached, the server process asks it to open the file, similar to how works for stdin, stdout, stderr. This makes special files like /dev/fd/X work (used by some shells). stdin, stdout and stderr and control mode are now just special cases of the same mechanism. This will also make it easier to use for other commands that read files such as source-file.
2019-06-13Use the right client when working out where to save or load the buffer,nicm

2018-07-11Expand formats in load-buffer and save-buffer.nicm
2017-04-22Memory leaks, from David CARLIER.nicm
2017-02-14Make source-file look for files relative to the client working directorynicm
(like load-buffer and save-buffer), from Chris Pickel. Also break the where-is-this-file code out into its own function for loadb and saveb.
2017-01-06Nits found with clang.nicm
2016-10-16Mass rename struct cmd_q to struct cmdq_item and related.nicm
2016-10-14Add CMD_AFTERHOOK flag to the easy commands that don't need any special ↵nicm
handling.
2016-10-10Add static in cmd-* and fix a few other nits.nicm
2016-03-05Do not use c->cwd or s->cwd if it is NULL, found by Ben Boeckel.nicm
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.
2015-11-14Push stdout and stderr to clients more aggressively, and add an event tonicm
continue if the send fails.
2015-11-10If realpath() fails just try the original path.nicm
2015-11-10Handle absolute paths properly, and don't use resolved path innicm
realpath() fails.
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).
2015-08-29paste_send_pane can be merged into cmd-paste-buffer.c now.nicm
2015-08-29Move struct paste_buffer out of tmux.h.nicm
2015-04-27Rewrite of the target resolution internals to be simpler and morenicm
consistent but with much less duplication, but keeping the same internal API. Also adds more readable aliases for some of the special tokens used in targets (eg "{start}" instead of "^"). Some behaviours may have changed, for example prefix matches now happen before fnmatch.
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.
2014-10-08Add xreallocarray and remove nmemb argument from xrealloc.nicm
2014-05-13Add support for named buffers. If you don't name a buffer, things worknicm
much as before - buffers are automatically named "buffer0000", "buffer0001" and so on and ordered as a stack. Buffers can be named explicitly when creating ("loadb -b foo" etc) or renamed ("setb -b buffer0000 -n foo"). If buffers are named explicitly, they are not deleted when buffer-limit is reached. Diff from J Raynor.
2014-04-24There is no longer a need for a paste_stack struct or for global_buffersnicm
to be global. Move to paste.c.
2014-04-16Memory leak in error path and unnecessary assignment, from clang.nicm
2014-04-07save-buffer needs to use O_TRUNC.nicm
2013-10-10Alter how tmux handles the working directory to internally use filenicm
descriptors rather than strings. - Each session still has a current working directory. - New sessions still get their working directory from the client that created them or its attached session if any. - New windows are created by default in the session working directory. - The -c flag to new, neww, splitw allows the working directory to be overridden. - The -c flag to attach let's the session working directory be changed. - The default-path option has been removed. To get the equivalent to default-path '.', do: bind c neww -c $PWD To get the equivalent of default-path '~', do: bind c neww -c ~ This also changes the client identify protocol to be a set of messages rather than one as well as some other changes that should make it easier to make backwards-compatible protocol changes in future.
2013-10-10Remove the barely-used and unnecessary command check() function.nicm
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.
2013-03-22Fix so capture-pane/save-buffer can work in control clients, from GeorgeNicholas Marriott
Nachman.
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
2012-05-21Instead of passing stdin/stdout/stderr file descriptors over imsg andNicholas Marriott
handling them in the server, handle them in the client and pass buffers over imsg. This is much tidier for some upcoming changes and the performance hit isn't critical. The tty fd is still passed to the server as before. This bumps the tmux protocol version so new clients and old servers are incompatible.
2012-03-21Fix save-buffer usage, from Kazuhiko Sakaguchi.Nicholas Marriott
2011-10-23Try to resolve relative paths for loadb and saveb (first using clientNicholas Marriott
working directory if any then default-path or session wd).
2011-10-23Plug a memory leak and update some comments, from Tiago Cunha.Nicholas Marriott
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.
2010-12-30Change from a per-session stack of buffers to one global stack which isNicholas Marriott
much more convenient and also simplifies lot of code. This renders copy-buffer useless and makes buffer-limit now a server option. By Tiago Cunha.
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.
2010-06-28Send all three of stdin, stdout, stderr from the client to the server, so thatNicholas Marriott
commands can directly make use of them. This means that load-buffer and save-buffer can have "-" as the file to read from stdin or write to stdout. This is a protocol version bump so the tmux server will need to be restarted after upgrade (or an older client used).
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.
2009-10-26Reset the umask right after fopen to avoid leaving it changed on error, noticedNicholas Marriott
by deraadt@.
2009-09-07Give each paste buffer a size member instead of requiring them to beNicholas Marriott
zero-terminated.
2009-07-26Make all messages sent between the client and server fixed size.Nicholas Marriott
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.
2009-07-13Having fixed flags for single-character getopt options is a bit hard toNicholas Marriott
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.
2009-06-01Import tmux, a terminal multiplexor allowing (among other things) a singleNicholas Marriott
terminal to be switched between several different windows and programs displayed on one terminal be detached from one terminal and moved to another. ok deraadt pirofti
