A little shell script that helps you rename a templated Phoenix project (note: might be out of date with current version of Phoenix)

rename_phoenix_app.sh

#!/bin/bash

rename_cwd() {
  cd . || return
  new_dir=${PWD%/*}/$1
  mv -- "$PWD" "$new_dir" &&
    cd -- "$new_dir"
}


if grep -R -l rename lib > /dev/null; then
  echo ""
else
  read -p "You've already renamed this app. Are you sure you want to rename it
  again? Y/n " -n 1 -r

  echo    # (optional) move to a new line
  if [[ $REPLY =~ ^[Nn]$ ]]; then
    exit 1
  fi
fi

read -p "Need to install tool 'rename' in order to globally rename files in this project. Is that ok? Y/n " -n 1 -r

echo    # (optional) move to a new line
if [[ $REPLY =~ ^[Yy]$ ]]
then
  brew install rename
else
  echo "Aborting"
  exit 1
fi

cat << EOF


What module name would you like to give this app? 

  Example: MyApp would create MyApp and MyAppWeb module prefixes, with a file
    structure like so:

      * lib/my_app/...
      * lib/my_app_web/..
      * test/my_app/...
      * test/my_app_web/...

      Note: it will also be used as the default name for your Heroku app when automatically deploying to Heroku later, ie my-app.herokuapp.com (you can skip this step if you'd like)
