* Make command exec functions return an enum rather than -1/0/1 values andNicholas Marriott2012-07-11
| | | | | | 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.

* 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.

within tmux. There is a global environment, copied from the external environment when the server is started and each sesssion has an (initially empty) session environment which overrides it. New commands set-environment and show-environment manipulate or display the environments. A new session option, update-environment, is a space-separated list of variables which are updated from the external environment into the session environment every time a new session is created - the default is DISPLAY.
