work is a small script which attaches to a particularly named tmux session if available, and creates it if not.

# The purpose of this script is to attach to a tmux session of a
# particular name if it exists, or create it if it does not.
#

# SESSION is the name of the tmux session.
SESSION="$USER-work"

# If possible, simply reattach.
tmux has-session -t "$SESSION"
if [ $? -eq 0 ]; then
	echo "Attaching to \"$SESSION\""

# Because we'll need to create a number of panes, define a function to
# do it.

# Arguments:
#  command to run in the new pane (will close the pane when terminated)
#  pane to split from (of the form "1" or "2")
#  direction in which to split ("h" or "v")
addpane() {
	tmux split-window -$3 -t "$SESSION":1.$2 "$1"
}

# The first pane is created along with the session, and can be given a
# command. It is important to note that if the command terminates, so
# too will the session. Leave it blank for a shell.

# Any additional panes will be added with the "addpane" command as
# defined above. The arguments to this are, in order, "command",
# "pane", and "direction." Note that when the command terminates, the
# pane will be removed. Leaving it blank will spawn a shell. The
# "pane" argument is the number of the pane to split from, such as 0
# or 1. Finally, the direction is either "h" or "v", which are
# "horozontal" and "vertical" respectively.

# 1 - emacs
#tmux new-session -d -s "$SESSION" #"command"
tmux new-session -d -s "$SESSION" "emacs -nw"

# 2 - zshp
#addpane "command" [0123...] [hv]
addpane "" 1 h

# 3 - irc
addpane "weechat-curses" 2 v

# Now all of the windows should be set up. Now, attach.
echo "Created and attaching to \"$SESSION\""
sleep 1
tmux select-window -t "$SESSION:0"
tmux attach -t "$SESSION"
