Bash Parse Arrays From Config File

Question

[array0]
value1=asdf
value2=jkl

[array1]
value1=1234
value2=5678

I want t

Answer 1

with bash v4, using associative arrays, store the properties from the config file as actual bash variables:

$ while read line; do 
    if [[ $line =~ ^"["(.+)"]"$ ]]; then 
        arrname=${BASH_REMATCH[1]}
        declare -A $arrname
    elif [[ $line =~ ^([_[:alpha:]][_[:alnum:]]*)"="(.*) ]]; then 
        declare ${arrname}[${BASH_REMATCH[1]}]="${BASH_REMATCH[2]}"
    fi
done < config.conf

$ echo ${array0[value1]}
asdf

$ echo ${array1[value2]}
5678

$ for i in "${!array0[@]}"; do echo "$i => ${array0[$i]}"; done
value1 => asdf
value2 => jkl

$ for i in "${!array1[@]}"; do echo "$i => ${array1[$i]}"; done
value1 => 1234
value2 => 5678
