Образец INI-файла

Я буду использовать следующий файл конфигурации INI в следующих примерах.

[main]

description = Sample configuration

timeout = 10

monitoring_interval = 20



[database]

server = db.example.org

port = 3306

username = dbuser

password = dbpass



[monitor]

servers[] = www.example.org

servers[] = proxy.example.org

servers[] = cache.example.org

servers[] = bastion.example.org

Спарсить весь INI-файл

Прочитаем и проанализируем весь INI-файл.

#!/bin/bash

# Read and parse simple INI file 



# Get INI section

ReadINISections(){

  local filename="$1"

  awk '{ if ($1 ~ /^[/) section=tolower(gensub(/[(.+)]/,"\1",1,$1)); configuration[section]=1 } END {for (key in configuration) { print key} }' ${filename}

}



# Get/Set all INI sections

GetINISections(){

  local filename="$1"



  sections="$(ReadINISections $filename)"

  for section in $sections; do

    array_name="configuration_${section}"

    declare -g -A ${array_name}

  done

  eval $(awk -F= '{ 

                    if ($1 ~ /^[/) 

                      section=tolower(gensub(/[(.+)]/,"\1",1,$1)) 

                    else if ($1 !~ /^$/ && $1 !~ /^;/) {

                      gsub(/^[ t]+|[ t]+$/, "", $1); 

                      gsub(/[[]]/, "", $1);

                      gsub(/^[ t]+|[ t]+$/, "", $2); 

                      if (configuration[section][$1] == "")  

                        configuration[section][$1]=$2

                      else

                        configuration[section][$1]=configuration[section][$1]" "$2} 

                    } 

                    END {

                      for (section in configuration)    

                        for (key in configuration[section])  

                          print "configuration_"section"[""key""]=""configuration[section][key]"";"

                    }' ${filename}

        )





}



if [ "$#" -eq "1" ] && [ -f "$1" ]; then

  filename="$1"

  GetINISections "$filename"



  echo -n "Configuration description: "

  if [ -n "${configuration_main["description"]}" ]; then

    echo "${configuration_main["description"]}"

  else

    echo "missing"

  fi

  echo



  for section in $(ReadINISections "configuration.ini"); do

    echo "[${section}]"

    for key in $(eval echo ${'!'configuration_${section}[@]}); do

            echo -e "  ${key} = $(eval echo ${configuration_${section}[$key]}) (access it using $(echo ${configuration_${section}[$key]}))"

    done

  done

else

  echo "missing INI file"

fi

Вывод будет выглядеть так.

$ parseini configuration.ini 

Configuration description: Sample configuration



[database]

  username = dbuser (access it using ${configuration_database[username]})

  server = db.example.org (access it using ${configuration_database[server]})

  password = dbpass (access it using ${configuration_database[password]})

  port = 3306 (access it using ${configuration_database[port]})

[main]

  description = Sample configuration (access it using ${configuration_main[description]})

  timeout = 10 (access it using ${configuration_main[timeout]})

  monitoring_interval = 20 (access it using ${configuration_main[monitoring_interval]})

[monitor]

  servers = www.example.org proxy.example.org cache.example.org bastion.example.org (access it using ${configuration_monitor[servers]})

Парсинг одного раздела в INI-файле

Прочитаем и проанализируем отдельный раздел в INI-файле.

#!/bin/bash

# Read and parse single section in INI file 





# Get/Set single INI section

GetINISection() {

  local filename="$1"

  local section="$2"



  array_name="configuration_${section}"

  declare -g -A ${array_name}

                    if ($1 ~ /^[/)

                    else if ($1 !~ /^$/ && $1 !~ /^;/) {

                      gsub(/^[ t]+|[ t]+$/, "", $1); 

                      gsub(/[[]]/, "", $1);

                      gsub(/^[ t]+|[ t]+$/, "", $2);

                      if (section == members) {
