vjt's tmux RVM + ViM IDE setup

1-session.sh

#!/bin/sh
#
# IDE Session starter - you should save this script as ~/bin/session, make it
# executable with chmod +x ~/bin/session, and then make a symlink to it for
# every application you want to start.

# E.g. ln -s session ~/bin/members creates a "members" symlink, and when you'll issue
# "members" on the command line this script will:

# Check if a tmux session named "members" exists
# If yes, it'll attach it and exit
# If no, it'll look for a "members" directory inside the defined base directory below
#    and for a ".tmuxrc" file inside it. The script then sets the GEM_HOME and GEM_PATH
#    environment variables, using the RVM environment file (change it if you use rbenv)
#    and it'll start a new tmux session with the application .tmuxrc file.
#    I do use a ".gemset" file in each app directory and my .rvmrc contains only
#    "rvm use `cat .gemset`". In this way only interactive shells will load RVM,
#    while other shells will live happily without it.

  # Change this line if you use something different than RVM.
  # The session needs the GEM_HOME and GEM_PATH variables.

Why do you need to symlink for each app and not to use like session members? Just change from basename $0 to basename $1

@jodosha I always try to save keystrokes :) and I find ln -s ~/bin/NAME session an acceptable tradeoff when starting a new project
