Short list of usernames, for wemux session only

README.txt

I mostly work in a wemux session so that my coworkers can SSH in and join me on
short notice, and have configured my tmux status bar to show the usernames of
everyone who's logged in.  However, I also sometimes have tmux sessions open with
personal projects, and don't need to see usernames in *those* sessions.  Also,
some people have really long usernames, so I want to assign them nicknames so
the entire list doesn't get truncated.

tmux.conf

set -g status-right " #[fg=green]#(wemux_user_list) #[fg=yellow]%R"

wemux_user_list

#!/usr/bin/env ruby

NICKNAMES = {
  'samlivingston-gray' => 'samlg',
}

def in_wemux_session?
  tmux_session = `tmux display-message -p '#S'`.strip
  tmux_session == 'wemux'
end

def short_user_list
  list = `wemux status_users`.strip.split(/\s+/)
  nicknames = list.map {|name| NICKNAMES[name] || name[0...6] }
  nicknames.join(', ')
end

puts short_user_list if in_wemux_session?
