* Clean up and simplify tmux command argument parsing.nicm2011-01-041-414/+0
| | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | using -p index, a target pane is now addressed with the normal -t window form but suffixed with a period and a pane index, for example :0.2 or mysess:mywin.1. An unadorned number such as -t 1 is tried as a pane index in the current window, if that fails the same rules are followed as for a target window and the current pane in that window used. As a side-effect this now means that swap-pane can swap panes between different windows. Note that this changes the syntax of the break-pane, clear-history, kill-pane, resize-pane, select-pane and swap-pane commands.
* Make all messages sent between the client and server fixed size.nicm2009-07-261-110/+1
| | | | | | | | | | | | | | 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.

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.
