Config::Std 0.0.4

Config::Std is a Perl module load and save configuration files in a standard format.

SYNOPSIS

use Config::Std;

# Load named config file into specified hash...
read_config demo2.cfg => my %config;

# Extract the value of a key/value pair from a specified section...
$config_value = $config{Section_label}{key};

# Change (or create) the value of a key/value pair...
$config{Other_section_label}{other_key} = $new_val;

# Update the config file from which this hash was loaded...
write_config %config;

# Write the config information to another file as well...
write_config %config, $other_file_name;

This module implements yet another damn configuration-file system.

The configuration language is deliberately simple and limited, and the module works hard to preserve as much information (section order, comments, etc.) as possible when a configuration file is updated.

See Chapter 19 of "Perl Best Practices" (OReilly, 2005) for the rationale for this approach.
