| | | | | | | | | | | | | | 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. GitHub issue 889; test case reported by Paul Johnson.

| | | | | | | | | | | | | | | | 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.

| | | | | | | | | 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.

* Add a command queue to standardize and simplify commands that call otherNicholas Marriott2013-03-24
| | | | | | | | | | | | | | | | | | | | | | 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.
* Fix error reporting for client commands by adding a flag toNicholas Marriott2013-03-24

| | | | | | 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.

* Do not require a client here, or pipe-pane will not work from theNicholas Marriott2011-07-30

* Change -t on display-message to be target-pane for the #[A-Z]Nicholas Marriott2011-03-29
| | | | replacements and add -c as target-client.
* Move all calls to fcntl(...O_NONBLOCK) into a function and clear theNicholas Marriott2011-01-08
| | | | | flag on the stdio file descriptors before closing them (fixes things like "tmux ls && cat").
* Clean up and simplify tmux command argument parsing.Nicholas Marriott2011-01-04
| | | | | | | | | | | | | | | | | | | 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.

* Do not call event_del() for signals after fork(), just use sigaction()Nicholas Marriott2010-08-19
| | | | | directly instead - calling libevent functions after fork() w/o event_reinit() is a bad idea, even if in this case it was harmless.
* Last change erroneously used the target argument for looking up theNicholas Marriott2010-06-14
| | | | | | | client which caused pipe-pane to fail when used from the command line. Instead pass NULL which should use the current client. Spotted by Tiago Cunha.

* Convert the window pane (pty master side) fd over to use a bufferevent.Nicholas Marriott2009-11-04
| | | | | The evbuffer API is very similar to the existing tmux buffer API so this was remarkably painless. Not many possible ways to do it, I suppose.
