Bug in Lib Function

[dylancopeland]

Hey there,

There is a bug in get_tmux_cwd() in lib.sh on OS X with tmux 1.7. The line that tries to get the current pane seems to be using the incorrect format specifier, "#D".

local env_name=$(tmux display -p "TMUXPWD_#D" | tr -d %)

In the man-page for tmux(1) it claims that "#D" is the pane unique ID however tmux show-environment doesn't have the ID. I propose that it is changed to use the "#I" and "#S" specifier so the window and pane can string can be constructed. Please see the following output to support this.

$ tmux -V
tmux 1.7
$ tmux display -p "TMUXPWD_#D"
TMUXPWD_%4
$ tmux show-environment
-DISPLAY
-SSH_AGENT_PID
-SSH_ASKPASS
SSH_AUTH_SOCK=/tmp/launch-4qmuFe/Listeners
-SSH_CONNECTION
TMUXPWD_0_0=/Users/dylan
TMUXPWD_1_0=/Users/dylan
TMUXPWD_2_0=/Users/dylan/Projects
TMUXPWD_3_0=/Users/dylan/Projects
-WINDOWID
-XAUTHORITY
$ tmux display -p "TMUXPWD_#I_#S"
TMUXPWD_3_0

Any objections?

Wow, didn't realize that the readme was updated with the new PS1 that uses "#D". My bad! 😄
