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

* Infrastructure and commands to manage the environment for processes startednicm2009-08-081-14/+16
| | | | | | | | | | | | | | | 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.
