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.
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.
2009-10-10Add "grouped sessions" which have independent name, options, current window andNicholas Marriott
so on but where the linked windows are synchronized (ie creating, killing windows and so on are mirrored between the sessions). A grouped session may be created by passing -t to new-session. Had this around for a while, tested by a couple of people.
2009-09-20Nuke unused variables and fix stupid error message.Nicholas Marriott
2009-09-20Move some common and untidy code for window link/unlink into generic functionsNicholas Marriott
instead of duplicating it in move/link window..
2009-08-13Add a base-index session option to specify the first index checked when lookingNicholas Marriott
for an index for a new window.
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.
2009-07-13Tidy up and improve target (-t) argument parsing:Nicholas Marriott
- move the code back into cmd.c and merge with the existing functions where possible; - accept "-tttyp0" as well as "-t/dev/ttyp0" for clients; - when looking up session names, try an exact match first, and if that fails look for it as an fnmatch pattern and then as the start of a name - if more that one session matches an error is given; so if there is one session called "mysession", -tmysession, -tmysess, -tmysess* are equivalent but if there is also "mysession2", the last two are errors; - similarly for windows, if the argument is not a valid index or exact window name match, try it against the window names as an fnmatch pattern and a prefix.
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
