Waaaay to verbose.

Here is a version without all the unecessary stuff around (untested, though):

#!/usr/bin/env bash
name=$([ -n "$1" ] && echo $1 || echo $(basename $(pwd)))

function exists {
  [[ $(tmux ls -F '#S') =~ "$name" ]]
}

if exists && [ -n "$TMUX" ]; then
  tmux attach -t $name
elif exists; then
  tmux switch-client -t $name
else
  tmux new -ds $name && tmux switch-client -t $name
fi

My slight variation would then be:

#!/usr/bin/env bash

name=${1-$(basename $(pwd))}

if [[ $(tmux ls -F '#S') =~ "$name" ]]; then
    if [ -n "$TMUX" ]; then
        tmux attach -t "$name"
    else
        tmux switch-client -t "$name"
    fi
else
  tmux new -ds "$name" && tmux switch-client -t "$name"
fi

I don’t remember where I found it, but I’ve been using this without any issues for quite some time:

#!/usr/bin/env bash

function tnew() {
  if [ -z "$1" ]; then
    session_name=$(basename $PWD:gs/./)
  else
    session_name=$1
  fi
  tmux new-session -As $session_name -n 'main'
}

From the manual: The -A flag makes new-session behave like attach-session if session-name already exists.
