Here is a bash-only YAML parser that leverages sed and awk to parse simple yaml files:

function parse_yaml {
   local prefix=$2
   local s='[[:space:]]*' w='[a-zA-Z0-9_]*' fs=$(echo @|tr @ '\034')
   sed -ne "s|^\($s\):|\1|" \
        -e "s|^\($s\)\($w\)$s:$s[\"']\(.*\)[\"']$s\$|\1$fs\2$fs\3|p" \

-e "s|^($s)($w)$s:$s(.*)$s$|\1$fs\2$fs\3|p" $1 |
