Run every check before merging a PR

.zshrc

lgtm() {
  yarn lint || { echo -e '\n\n \e[31mSomething went wrong: javascript linting\e[m \n\n' && return false }
  rubocop -a || { echo -e '\n\n \e[31mSomething went wrong: ruby linting\e[m \n\n' && return false }
  yarn test || { echo -e '\n\n \e[31mSomething went wrong: javascript testing\e[m \n\n' && return false }
  rspec || { echo -e '\n\n \e[31mSomething went wrong: ruby testing\e[m \n\n' && return false }

  if [[ -n $(git status -s) ]]; then
    git status
    echo -e '\n\n \e[33mAll good, but git status is dirty\e[m \n\n'
  else
    echo -e '\n\n \e[32mAll good, LGTM!\e[m  \n\n'
  fi

  return true
}

rubocop -a -> rubocop, so it forces failure similar to CI

cool
