#vagrant helper functions for brining up and shutting down the machines
#deps: - vagrant (of course)
       - jq - Command-line JSON processor
       - fzf - command-line fuzzy finder

vagrant_list () {
        tmp=$(cat ~/.vagrant.d/data/machine-index/index | jq '.machines[] | {name, vagrantfile_path, state}' | jq '.name + "," + .state  + "," + .vagrantfile_path'| sed 's/^"\(.*\)"$/\1/'| column -s, -t | sort -rk 2 | fzf )
