u do parse args like this ?

t='"${arg#-?}"' # cut prefix for num only
 declare -A match=(
"-p+([[:digit:]])" "printf 'p %s\\n' $t"
"-g+([[:digit:]])" "printf 'g %s\\n' $t"
-q 'printf q\\n'
 )

set -- -q -g55 -p727

   for arg ; do
  for m in "${!match[@]}" ; do
 if [[ $arg == $m ]] ; then
eval "${match[$m]}"
continue 2
 fi
  done
printf 'nomatch %s\n' "${arg@Q}"
   done

~ $ bash c.1
q
g 55
p 727

How can I handle the aforementioned functionality in a clear and compact
